Ingredients

Instructions

  1. Step 1: Preheat oven to 275°F. Rub 3 pounds beef brisket evenly with 1 tablespoon salt, 1 tablespoon black pepper, 2 teaspoons smoked paprika, 1 teaspoon garlic powder, and 1 teaspoon onion powder to create a spice crust.
  2. Step 2: Heat 2 tablespoons olive oil in a large oven-safe skillet over medium-high heat. Sear the brisket for 3-4 minutes per side until a deep brown crust forms, then remove from heat.
  3. Step 3: In a bowl, whisk together 1/4 cup yellow mustard, 1/4 cup apple cider vinegar, 1/2 cup ketchup, 2 tablespoons brown sugar, 1 tablespoon Worcestershire sauce, 1 teaspoon liquid smoke, and 1 teaspoon chili powder until smooth and well combined.
  4. Step 4: Brush the entire surface of the seared brisket with half of the barbecue sauce. Cover the skillet tightly with foil and roast in the preheated oven for 4 hours, basting with remaining sauce every hour.
  5. Step 5: After 4 hours, remove foil and roast uncovered for an additional 30 minutes to caramelize the glaze, until the sauce thickens and the edges are slightly crispy.
  6. Step 6: Let the brisket rest for 15 minutes before slicing thinly against the grain. Serve with extra BBQ sauce on the side.
