- 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.
