Ingredients

Instructions

  1. Step 1: In a food processor, combine 1/2 cup fresh basil leaves, 1/4 cup pine nuts, 1/4 cup grated parmesan cheese, 3 garlic cloves, and 1/3 cup olive oil. Pulse until a coarse pesto forms, scraping down sides as needed.
  2. Step 2: Mix the pesto with 3 tablespoons Dijon mustard, 2 teaspoons kosher salt, 1 teaspoon black pepper, 1 teaspoon smoked paprika, and 1 teaspoon onion powder to form a thick rub.
  3. Step 3: Trim excess fat from 5 pounds beef brisket and pat dry. Rub the mustard-pesto mixture all over the brisket evenly, pressing it into the meat.
  4. Step 4: Preheat your smoker to 225°F. Place the brisket fat-side up on the smoker grate and smoke for approximately 10-12 hours or until the internal temperature reaches 203°F, spritzing with apple juice every 2 hours to maintain moisture.
  5. Step 5: Remove the brisket from the smoker and wrap tightly in butcher paper. Let rest for 1 hour before slicing thinly against the grain. Serve with your favorite sides.
