Step By Step Instruction To Make Brisket Fajitas With Sautéed Onions and Bell Peppers
This recipe is quick to make and easy to customize. Just a few simple steps and you’ll have restaurant-worthy fajitas on your plate.
Step 1: Prepare the Brisket
If using leftover or pre-cooked brisket, slice it thinly across the grain. Place it in a bowl and toss with olive oil, cumin, chili powder, smoked paprika, salt, pepper, and lime juice. Let it sit at room temperature while preparing the vegetables.
Step 2: Sauté the Onions and Peppers
Heat olive oil in a large skillet over medium-high heat. Add the sliced onions and cook for 2–3 minutes until they begin to soften. Add the bell peppers, garlic powder, salt, and pepper. Cook for another 6–8 minutes, stirring occasionally, until vegetables are tender and slightly charred.
Step 3: Warm and Sear the Brisket
In a separate skillet over medium-high heat, warm the brisket slices until heated through and slightly crisp on the edges, about 4–5 minutes. If using fresh, uncooked brisket, sear the meat on both sides until fully cooked and browned, then slice thinly.
PRO TIP: For extra char and flavor, cook the onions and peppers in a cast iron skillet and finish the brisket under a broiler for 1–2 minutes.
Step 4: Assemble and Serve
Warm the tortillas on a hot skillet or directly over a gas flame until soft and slightly toasted. Fill each tortilla with sliced brisket, sautéed onions, and bell peppers. Add your favorite toppings like sour cream, salsa, guacamole, or a squeeze of fresh lime juice.
