Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F. Season 1.5 lbs beef brisket with 1/2 tsp salt and 1/4 tsp black pepper. Heat 1 tbsp olive oil in a Dutch oven over medium-high heat, sear brisket on all sides until browned, about 5 minutes per side.
  2. Step 2: Remove brisket, add 1 diced onion and 3 minced garlic cloves to pot, sauté for 3 minutes until fragrant. Return brisket to pot, add 1 cup beef broth, 1 tsp cumin, 1 tsp smoked paprika, and remaining 1 tbsp olive oil.
  3. Step 3: Cover and transfer to oven. Braise for 3.5 hours until fork-tender. Remove brisket, let rest 15 minutes, then shred with two forks.
  4. Step 4: Warm 8 corn tortillas in a dry skillet over medium heat for 30 seconds per side. Assemble tacos: place shredded brisket on tortillas, top with 1 cup pickled red onions, 1 sliced avocado, and 1/4 cup chopped cilantro.
