Ingredients

Instructions

  1. Step 1: Preheat your grill to medium-high heat (about 400°F). Rub 2 lbs beef brisket evenly with 2 tbsp olive oil and 2 tbsp Cajun seasoning, massaging the spices into the meat.
  2. Step 2: Grill the brisket directly over the heat for 5-6 minutes per side, then move to indirect heat and cook for an additional 45 minutes covered, until the internal temperature reaches 195°F and the meat is tender.
  3. Step 3: While the brisket cooks, thinly slice 1 medium red onion into rings. In a bowl, combine 1/2 cup apple cider vinegar, 1 tbsp sugar, and 1 tsp salt; stir until dissolved. Add the sliced onions and let them pickle for at least 30 minutes, stirring occasionally.
  4. Step 4: Warm 8 corn tortillas on the grill for about 30 seconds per side until pliable and slightly charred.
  5. Step 5: Slice the rested brisket thinly against the grain. Assemble the tacos by placing brisket slices on tortillas, topping with pickled onions and 1/4 cup chopped cilantro. Serve with lime wedges for squeezing over the top.
