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: Combine 2 tbsp kosher salt, 1 tbsp black pepper, 1 tbsp paprika, and 1 tsp garlic powder; rub this spice mix evenly over the entire 4 lbs beef brisket. Let it rest at room temperature for 30 minutes.
3. Step 3: Place the brisket fat side up on the smoker grate, add the soaked hickory chips to the smoker box, and smoke for about 6 hours, maintaining 225°F, until the internal temperature reaches 195°F.
4. Step 4: While the brisket smokes, halve and char 1 large onion over a grill or gas flame until blackened on the edges, about 5 minutes per side. Dice the charred onion.
5. Step 5: Heat 2 tbsp olive oil in a saucepan over medium heat, add the diced charred onion, and sauté for 3 minutes until fragrant. Stir in 1/4 cup apple cider vinegar, 1/2 cup ketchup, 2 tbsp brown sugar, 1 tsp smoked paprika, 1 tsp hot sauce, and 1/4 cup water. Simmer gently for 10 minutes until the sauce thickens and coats the back of a spoon.
6. Step 6: Remove the brisket from the smoker and let it rest for 20 minutes before slicing against the grain. Serve the sliced brisket with the charred onion barbecue sauce spooned over the top.
