Instructions

  1. Step 1: Combine 2 tbsp kosher salt, 2 tbsp black pepper, 1 tbsp smoked paprika, 1 tbsp garlic powder, and 1 tbsp onion powder in a bowl. Rub this spice mix evenly over all sides of the 4 lb trimmed beef brisket. Let rest at room temperature for 1 hour.
  2. Step 2: Prepare pickled onions by mixing 1 cup apple cider vinegar, 1 cup water, and 1 tbsp sugar in a jar until sugar dissolves. Add 1 large thinly sliced red onion and let sit for at least 30 minutes.
  3. Step 3: Preheat smoker or grill to 225°F. Place brisket fat-side up on the smoker and smoke for approximately 8-10 hours, or until internal temperature reaches 200°F and meat is tender.
  4. Step 4: Remove brisket and let rest for 30 minutes before slicing thinly against the grain.
  5. Step 5: Warm 8 soft sandwich buns and spread each with 2-3 tbsp Kansas City-style BBQ sauce. Pile sliced brisket on buns and top with pickled onions. Serve immediately.
