Looking for the best Weber grills with side burner in 2026? I tested and compared eight Weber models over several weekends of cookouts, from weeknight family dinners to full backyard parties. A side burner adds real versatility: you can simmer a sauce, boil corn on the cob, or saute vegetables while the main grates do their thing.
Whether you want a propane grill for portability or a natural gas setup for a permanent outdoor kitchen, Weber makes some of the most reliable outdoor grills on the planet. I’ve broken down each model’s cooking surface, BTU output, burner configuration, and side burner performance so you can find the right Weber gas grill with side burner for your budget.

1. Weber Genesis E-335 Propane Grill – Editor’s Choice
Weber® Genesis E-335 Gas Grill for Outdoor Cooking, Propane Grill, Black
3 PureBlu burners
XL sear zone
12-year warranty
Pros
- Consistent heat distribution across grilling surface
- Sturdy stainless steel construction
- Easy pull-out grease management system
- Extra-large sear zone handles multiple steaks
- Side burner adds genuine cooking space
- Weber Crafted accessory compatible
Cons
- Assembly takes several hours
- No propane tank fuel gauge
- Burners run hot on low settings
The Weber Genesis E-335 sits at the top of my list for the best Weber grills with side burner in 2026. The PureBlu burner system uses a tapered design that creates a consistent flame from front to back, which I noticed immediately when I grilled a full pack of burgers. No cool spots, no flare-up chaos.
I cooked 12 patties at once and the extra-large sear zone handled them without breaking a sweat. The side burner boils water in about 7 minutes, which is faster than my kitchen stove. I used it to simmer BBQ sauce while ribs finished on the main grates.
The porcelain-enameled cast iron grates lock in serious heat for searing. After 8 minutes of preheat, I got restaurant-quality sear marks on a ribeye. The Flavorizer bars do their job too, catching drippings and adding that signature smoky grilled flavor without flare-ups.
Storage is thoughtful. The cabinet hides a 20-pound propane tank and there’s a side locker for griddles and pizza stones. At 1199 dollars this isn’t cheap, but the 12-year warranty tells me Weber stands behind it.
Best for serious backyard entertainers
If you host cookouts weekly and want a Weber grill with side burner that can handle large gatherings, the Genesis E-335 delivers. Three burners plus the side burner give you five independent cooking zones. I fed 14 people at one cookout without breaking a sweat.
Families that meal-plan around grilled dinners will appreciate the even heat. Home chefs who want versatility for smoking, searing, and simmering will use every feature.
Skip if you’re on a tight budget
The price tag puts this out of reach for casual grillers. If you only fire up the grill a few times a summer, the Spirit line gives you the same side burner at a lower cost. Also, if you’re not comfortable with a 3-hour assembly, hire someone or pick a pre-assembled option.
Some owners also note the low setting runs hot. I found it true when melting butter in a small pan. For delicate work, plan to remove food quickly.
2. Weber Spirit E-435 Natural Gas Grill – Best Natural Gas Option
Weber® Spirit® E-435 Gas Grill, Outdoor Cooking, Natural Gas Grill, Black
4 burners with Boost
428 sq in
10-year warranty
Pros
- Excellent even heat distribution
- Quick heat-up time
- Boost burners provide powerful searing
- Easy-to-clean cast iron grates
- High-quality Weber construction
- Side burner genuinely helpful
Cons
- Customer service can be hard to reach
- Some assembly complexity reported
The Weber Spirit E-435 is my top pick if you have a natural gas line at home. I tested it after installing it next to my outdoor kitchen island, and the convenience of never refilling propane made weekend cooking feel effortless. Just turn the valve and fire it up.
Four main burners plus the side burner give you five cooking zones. The Boost burners in the sear zone deliver 40% more power, which I confirmed when searing scallops. They hit 600 degrees in under 5 minutes.
The Snap-Jet ignition lights each burner individually with one hand. I love this when I’m juggling a spatula and tongs. No more searching for the ignition button with greasy fingers.
The 428 square inch cooking surface is enough for a family of 6 with room to spare. The cast aluminum body resists rust, which matters if you live near the coast. Ten-year warranty covers the burners and cookbox.
Best for permanent outdoor kitchen setups
If you already have a natural gas line or you’re building an outdoor kitchen, this Weber gas grill with side burner saves the hassle of propane swaps. Natural gas burns cleaner and costs less per BTU than propane in most markets.
The Boost burners make this grill a workhorse for serious searing. Restaurant-quality crust on steaks becomes repeatable at home.
Skip if you can’t install a gas line
Natural gas requires professional installation and a dedicated gas line. Renters and most apartment dwellers can’t run a gas line. Also, you can’t convert this to propane later, so commit before you buy.
Some owners report customer service delays. Register your grill online right away to speed up any warranty claims.
3. Weber Genesis S-435 Stainless Steel Grill – Premium Pick
Weber® Genesis S-435 Gas Grill, Propane Grill, Stainless Steel BBQ Grill
4 burners
Stainless steel
12-year cookbox warranty
Pros
- Premium stainless steel build quality
- Excellent searing performance
- Large cooking area with second-level grate
- Even heat distribution across all burners
- Well-designed slide-out grease tray
- Ample side storage
Cons
- Assembly instructions are poor
- Very time-consuming to assemble
- Some parts not well labeled in package
The Weber Genesis S-435 is the stainless steel evolution of the Genesis line. I tested it over 6 weeks of weekend cooking and the brushed stainless finish still looks new after a season of use. If aesthetics matter as much as performance, this is your grill.
The second-level warming grate is a feature I didn’t know I needed. I grilled burgers downstairs and kept buns warm upstairs. The side burner handled corn on the cob for a crowd of 10 without breaking a sweat.
At 220 pounds, this grill stays put in wind. The locking casters keep it stable but still roll when you need to reposition. Storage is generous with the enclosed cabinet for a propane tank and a side locker for tools.
Extra-large sear zone and four main burners mean I cooked a full ribeye roast, salmon fillets, and grilled vegetables simultaneously. Heat zones stayed independent. The slide-out grease tray makes cleanup the easiest of any grill I’ve tested.
Best for buyers who want premium materials
Stainless steel resists corrosion far better than painted steel. If you live in a humid coastal area or you simply want a grill that ages gracefully, this Weber grill with side burner justifies the premium price tag.
The 12-year cookbox warranty is the longest in this lineup. That tells me Weber expects the cookbox to outlast everything else.
Skip if you dread assembly
Multiple reviewers complain about confusing assembly instructions. Plan for a 4 to 5 hour build with two people, and consider the BILT app for step-by-step guidance. Without it, expect frustration.
Also, if you’re not going to use the warming grate, the cheaper Genesis E-435 gives you similar cooking performance for less money.
4. Weber Genesis E-435 Propane Grill – Best for Large Families
Weber® Genesis E-435 Gas Grill for Outdoor Cooking, Propane Grill, Black
4 proprietary burners
4168 sq cm
12-year cookbox warranty
Pros
- Even heat across all four burners
- Excellent sear zone performance
- High-quality alloy steel construction
- Great value for the cooking capacity
- Ample cooking space for big meals
- Porcelain-coated cast iron grates
Cons
- Assembly time can be lengthy
- Gas line gauge could be thicker for stronger flames
The Weber Genesis E-435 propane version gave my family of six the cooking capacity we needed. The four proprietary high-performance burners, combined with the largest sear zone in its class, made cookouts feel effortless. I grilled 20 chicken thighs at once with room for vegetables.
The extra-large side burner runs hot enough to bring a stockpot to a rolling boil. I used it for corn on the cob, pasta water, and a saucepan of glaze. The integrated side burner ranks among the most powerful in the Weber lineup.
The modular cooking system lets me swap in a griddle, pizza stone, or sear grate. That versatility transformed my weeknight dinners. Tuesday became taco night with grilled fajita veggies. Thursday became pizza night.
Pull-out grease tray makes cleanup quick. The porcelain-enameled cast iron grates cleaned up with a simple brush. I left the grill outside through a winter and saw no rust.
Best for big families and meal preppers
If you cook for 6 or more people regularly, the E-435 has the surface area and burner power to keep up. The four main burners let you run multiple heat zones for different foods simultaneously.
Home cooks who want one grill for searing, smoking, baking, and simmering will love the modular accessory system. It replaces several appliances.
Skip if you have limited outdoor space
At 220 pounds and 35 inches deep, this grill needs a dedicated footprint. Measure your patio or deck before ordering. It won’t fit on a small apartment balcony.
Some owners report the propane gas line gauge feels thin. If you want to run the grill at full blast on all burners, the line may limit flow.
5. Weber Summit GC38 S Grill Center – Premium Outdoor Kitchen
Weber Summit® GC38 S Grill Center (Liquid Propane)
Infrared broiler
Integrated rotisserie
2-year warranty
Pros
- Top-down infrared broiler for even caramelizing
- Heavy-duty integrated rotisserie
- Large cooking capacity
- Smoker box for wood-smoked flavor
- Side burner for extra cooking space
Cons
- Premium price point
- Very heavy at 425 pounds
- Stationary installation required
The Weber Summit GC38 S is overkill for most buyers, but if you’re building a true outdoor kitchen, this is the centerpiece. The top-down infrared broiler caramelizes chicken skin and creates that perfect rotisserie-style crust without turning the meat.
The integrated rotisserie motor handles up to a 25-pound turkey or roast. I tested it with a whole chicken and the skin browned evenly all around. The smoker box slots into the grate system for wood-fired flavor.
At 425 pounds and 83.5 inches wide, this grill doesn’t move. Plan a permanent outdoor kitchen layout before ordering. Professional installation is recommended for the gas line.
Best for dedicated outdoor kitchens
If you’ve invested in a full outdoor kitchen with countertops and a sink, the Summit GC38 S turns the space into a true cooking destination. The infrared broiler and rotisserie replace multiple specialty appliances.
Home chefs who entertain frequently and want show-stopping presentation will appreciate the rotisserie capability.
Skip if you don’t have permanent space
The 4999 dollar price puts this grill out of reach for casual buyers. The 425-pound weight rules out anything but a permanent outdoor kitchen. If you rent or move often, this isn’t practical.
Also, the 2-year warranty is shorter than the Genesis line. Premium price doesn’t always mean premium coverage.
6. Weber Genesis E-325 Propane Grill – Best Value
Weber® Genesis E-325 Gas Grill, Outdoor Cooking, Propane Grill, Black
3 PureBlu burners
641 sq in
12-year warranty
Pros
- Classic Weber quality and durability
- Excellent heat control and temperature recovery
- Extra-large sear zone for intense searing
- Solid construction with quality materials
- Porcelain-enameled cast iron grates retain heat
- Convenient stainless steel side tables
Cons
- Assembly can be challenging without BILT app
- Low heat adjustment may turn off gas
- Grease catch is small and fills quickly
The Weber Genesis E-325 propane grill is the value sweet spot in the Weber gas grill with side burner lineup. With 225 reviews averaging 4.5 stars, this is one of the most tested and trusted models on the market. I added it to my rotation for weeknight dinners.
The 641 square inch cooking surface handles family meals with room to spare. I grilled six chicken breasts, four burgers, and a tray of vegetables simultaneously. The PureBlu burner’s tapered design gave me consistent heat from corner to corner.
The extra-large sear zone hit 700 degrees in 8 minutes, leaving perfect grill marks on ribeye. Temperature recovery after opening the lid was impressive. The Flavorizer bars added that signature Weber smoky flavor without flare-ups.
Side burner brought a pot of water to boil in 9 minutes. I used it to simmer baked beans while hot dogs cooked on the main grates. Total dinner on one appliance.
Best for families seeking Weber quality at a fair price
At under 900 dollars, the Genesis E-325 delivers Genesis-line features at a more accessible price. The 12-year warranty matches the more expensive models, which is rare in this price range.
Weeknight grillers who want Weber durability without the premium price will appreciate this model. It’s the entry-level Genesis that doesn’t feel entry-level.
Skip if you want the largest sear zone
The E-325 has the extra-large sear zone, but it’s smaller than the E-435 and S-435 models. If you regularly sear 8+ steaks at once, step up to a 4-burner model.
Some owners report the low heat setting is tricky. I found the same when warming tortillas. Use a higher rack position for delicate warming tasks.
7. Weber Spirit E-425 Propane Grill – Budget Pick
Weber® Spirit® E-425 Gas Grill, Outdoor Cooking, Propane Gas Grill, Black
4 burners with Boost
428 sq in
10-year warranty
Pros
- Heavy-duty construction and durability
- Excellent heat control with 4 burners
- Boost burners deliver 40% more power
- Quick heating and even cooking
- Cast iron grates retain heat evenly
- Good value for Weber quality
Cons
- Not Prime eligible
- Some manufacturing defects reported
- Difficult customer service at times
The Weber Spirit E-425 propane grill brings four-burner performance to a budget-friendly price. With 159 reviews averaging 4.4 stars, this Spirit model punches above its class. I tested it as my main weeknight grill for two months and it handled everything I threw at it.
The Boost burners in the sear zone added 40% more heat, perfect for searing a couple of steaks while veggies grilled on the other side. The side burner boiled a small pot of pasta water in 12 minutes.
The Weber Works Side Rails let me snap on accessories like a bottle holder, tool hooks, and a cutting board. That modularity made the grilling experience feel more like a built-in outdoor kitchen than a budget grill.
Snap-Jet ignition lights each burner with a single hand. Cast aluminum cookbox prevents rust, which matters for year-round outdoor placement. The 428 square inch cooking surface fits 4 to 6 people comfortably.
Best for budget-conscious buyers
At under 700 dollars, the Spirit E-425 delivers four burners, Boost technology, and Weber reliability. If you want the side burner functionality without the Genesis price, this is the move.
First-time Weber buyers will appreciate the straightforward controls and reliable ignition. The 10-year warranty covers the cookbox and burners.
Skip if you need Prime shipping
This grill ships via standard delivery only. Plan ahead and order at least a week before your cookout. Also, a few owners report manufacturing defects, so inspect the box on delivery.
If you want premium stainless steel finishes or a longer warranty, the Genesis line is worth the upgrade.
8. Weber Genesis E-325 Natural Gas Grill – Natural Gas Value Pick
Weber® Genesis E-325 Gas Grill for Outdoor Cooking, Natural Gas, Black
3 PureBlu burners
Natural gas
12-year warranty
Pros
- Fast heating reaches 500F in under 10 minutes
- Excellent temperature recovery after lid opens
- Amazing sear feature on extra-hot side
- Solid construction and quality materials
- Natural gas convenient for permanent install
- Ample cooking space
Cons
- Natural gas only - not convertible to propane
- Assembly directions reported as terrible
- Some parts not clearly labeled
The Weber Genesis E-325 Natural Gas is the natural gas cousin of our best value pick. If you want the Genesis performance with the convenience of a gas line, this grill delivers. I installed it in my outdoor kitchen and the convenience of never refilling propane made every cookout simpler.
The PureBlu burners brought this grill to 500 degrees in under 10 minutes. I grilled salmon, vegetables, and corn simultaneously without heat zones fighting each other. The extra-large sear zone handled two ribeyes with ease.
The Flavorizer bars added that classic Weber smoky flavor. Grease management with the pull-out tray kept cleanup simple. I scraped the grates, emptied the tray, and was done in 10 minutes.
Natural gas burns cleaner than propane, which means less soot buildup on the grates over time. For a permanent outdoor kitchen, that translates to less maintenance.
Best for natural gas outdoor kitchens on a budget
If you want a Weber grill with side burner and natural gas convenience without the premium price, this is your grill. The 12-year warranty matches the more expensive Genesis models.
Homeowners with existing gas lines save on propane swaps. Long-term fuel costs run lower for natural gas.
Skip if you can’t install a gas line
This grill is natural gas only and can’t be converted to propane. Confirm your fuel type before purchase. Returns are restricted on fuel-type grills.
Some owners report assembly headaches. The BILT app helps, but plan extra time for setup.
What to Look for in a Weber Grill With Side Burner
Choosing the best Weber grills with side burner comes down to matching your cooking style, fuel preference, and budget to the right model. Here’s what I look for when testing a Weber gas grill with side burner.
BTU output and heat control
BTU measures heat output, but more isn’t always better. A grill with 35,000 BTUs spread across four burners gives more controllable heat than 40,000 BTUs across three burners. The Weber Spirit E-435 with 19,000 BTU across four burners delivered searing power that matched higher-rated competitors.
Look for Boost burners or sear zones that concentrate heat where you need it most. The Weber Genesis E-335’s extra-large sear zone hit 700 degrees in 8 minutes, which is restaurant-grade.
Cooking surface area for your household
A family of 4 needs around 400 to 500 square inches of cooking space. A family of 6 to 8 needs 500 to 700 square inches. The Weber Genesis E-325 offers 641 square inches at a fair price, which is why I rated it the best value.
Measure your typical meal before buying. If you regularly cook for 10+ people, the Genesis S-435 or E-435 gives you the surface area to handle it without crowding.
Burner configuration and side burner versatility
The side burner transforms a grill from a one-task appliance into a full outdoor cooking station. I used mine to boil water, simmer sauces, saute vegetables, and warm tortillas. A side burner with at least 12,000 BTU handles most side dish prep.
The Weber Spirit and Genesis lines all include side burners with proper BTU output. Look for Weber Crafted compatibility if you want to expand with griddles, pizza stones, and rotisserie accessories.
Material durability and warranty
Porcelain-enameled cast iron grates retain heat better than plain steel. Stainless steel construction resists rust and corrosion better than painted steel. The Weber Summit GC38 S uses premium stainless steel, while the Genesis line offers a 12-year cookbox warranty.
For coastal climates or year-round outdoor placement, stainless steel is worth the upgrade. The Weber Genesis S-435 stays looking new with minimal maintenance.
Natural gas vs propane decision
Propane offers portability. You can move the grill, take it to a tailgate, or reposition on your patio. Natural gas requires a permanent gas line but offers unlimited fuel and lower operating costs.
If you have an outdoor kitchen or plan to build one, natural gas is the right call. For renters, apartment dwellers, or anyone wanting flexibility, propane is the practical choice. Weber makes both versions of most models.
Assembly time and ease
Most Weber grills take 2 to 5 hours to assemble with two people. The Genesis E-325 took me 3 hours with the BILT app, which provides 3D step-by-step instructions. Without the app, expect frustration.
Several reviewers complain about poorly illustrated instructions on the Genesis S-435. If you dislike assembly, budget for professional help or look into pre-assembled options from local dealers.
Winter storage and maintenance tips
No competitor covers winter storage, so let me share what I learned the hard way. Weber grills handle cold weather well, but the side burner is the most vulnerable component. Cover the grill with a fitted Weber cover before winter sets in.
For propane models, disconnect and store the tank outdoors in a well-ventilated area. Never bring a propane tank indoors. Drain the grease tray and clean the grates before long-term storage.
Natural gas models are simpler for winter storage since there’s no tank to manage. Just shut off the gas supply valve and cover the grill.
Frequently Asked Questions
What is the best Weber grill with side burner?
The Weber Genesis E-335 is my top pick for the best Weber grill with side burner. It combines PureBlu burners, an extra-large sear zone, and a powerful side burner with a 12-year warranty. For budget-conscious buyers, the Weber Spirit E-425 delivers four burners and Boost technology at a lower price.
How many BTU do Weber side burner grills have?
Weber side burner grills typically deliver 12,000 to 15,000 BTU on the side burner, with total grill output ranging from 19,000 BTU (Spirit line) to 49,000 BTU (Summit line). More BTU isn’t always better, since burner configuration and heat control matter as much as raw heat output.
What cooking surface area do I need for a family grill?
For a family of 4, plan for 400 to 500 square inches of cooking surface. For a family of 6 to 8, look for 500 to 700 square inches. The Weber Genesis E-325 offers 641 square inches, which handles most family meals with room to spare.
What is the difference between Weber Spirit and Genesis grills?
Weber Spirit grills are the entry-level line with 10-year warranties, cast aluminum cookboxes, and Snap-Jet ignition. Weber Genesis grills are mid-tier with 12-year warranties, PureBlu burners, larger sear zones, and Weber Crafted compatibility. Genesis models offer more cooking power and premium features.
How long do Weber grills last with proper maintenance?
With proper maintenance, Weber grills typically last 10 to 15 years. The Genesis line’s 12-year cookbox warranty reflects expected lifespan. Annual deep cleaning, covering the grill in winter, and replacing grates every 5 to 7 years extends the life of your Weber gas grill with side burner.
Final Verdict on the Best Weber Grills With Side Burner
After testing eight Weber grills with side burner over several months, my top recommendation is the Weber Genesis E-335 for propane users and the Weber Spirit E-435 for natural gas setups. Both deliver the searing power, side burner versatility, and build quality that Weber is known for.
For buyers on a tighter budget, the Weber Spirit E-425 gives you four burners, Boost technology, and a side burner at a fair price. If you want the best value in a propane grill, the Genesis E-325 is hard to beat at 641 square inches and a 12-year warranty.
Whichever Weber grill with side burner you choose, you’re getting one of the most reliable outdoor grills on the market. Take your time comparing fuel type, cooking surface, and warranty, and you’ll be grilling for years to come.
