Rub the brisket with salt, pepper, garlic powder, cumin, and chili powder.
Let it sit for 30 minutes to absorb the flavors.
Step 2: Sear the Brisket
Preheat oven to 300°F (150°C).
In a large Dutch oven or oven-safe pot, heat olive oil over medium-high heat.
Sear the brisket on all sides, about 4–5 minutes per side, until browned. Remove and set aside.
Step 3: Cook the Aromatics
In the same pot, sauté onion, bell pepper, and garlic for 5 minutes until softened.
Add diced tomatoes, beef broth, smoked paprika, cumin, and cayenne. Stir to combine.
Step 4: Slow-Cook the Brisket
Return the brisket to the pot, cover with a lid or foil.
Bake for 3–4 hours, until the brisket is fork-tender.
Step 5: Shred and Toss
Remove brisket from the pot and shred with two forks.
Toss shredded beef in the juices from the pot to soak up the flavors.
Step 6: Assemble Tacos
Warm tortillas.
Fill with shredded brisket and top with diced onions, cilantro, lime, salsa, avocado, and optional lettuce or cabbage.
