Instructions

  1. Step 1: Mix 2 tbsp kosher salt, 1 tbsp black pepper, 1 tbsp garlic powder, and 1 tbsp onion powder, then rub evenly over all sides of 5 lbs beef brisket. Let rest uncovered in the fridge for 4 hours.
  2. Step 2: Prepare your smoker to 225°F and add 3 large hickory or oak wood chunks for smoke.
  3. Step 3: Place the brisket fat side up on the smoker grate and smoke for 8-10 hours until internal temperature reaches 195°F, maintaining steady temperature.
  4. Step 4: While the brisket smokes, whisk together 1/2 cup yellow mustard, 1/3 cup apple cider vinegar, 2 tbsp honey, and 1/2 cup gluten-free BBQ sauce in a bowl until smooth.
  5. Step 5: Once done, wrap brisket in foil and let rest for 30 minutes. Slice against the grain and serve with the tangy mustard BBQ sauce on the side.
