Ingredients

Instructions

  1. Step 1: Preheat your smoker to 225°F and soak 2 cups of hickory wood chips in water for 30 minutes.
  2. Step 2: Spread 1/4 cup yellow mustard evenly over the entire 5 lb beef brisket to help the rub adhere and add tangy flavor.
  3. Step 3: In a small bowl, combine 2 tbsp kosher salt, 1 tbsp black pepper, 1 tbsp paprika, 1 tbsp garlic powder, and 1 tbsp onion powder. Rub this spice mixture evenly over the mustard-coated brisket.
  4. Step 4: Place the brisket fat-side up on the smoker grate, add the soaked hickory wood chips to the smoker box, and smoke for about 8 hours, or until internal temperature reaches 195°F and the meat is tender.
  5. Step 5: Remove the brisket and wrap tightly in butcher paper. Let it rest for 1 hour before slicing across the grain into 1/4-inch thick slices.
