Instructions

Step 1: Preheat your smoker to 225°F and add 2 cups soaked apple wood chips for smoke flavor. Rub 4 lbs beef brisket flat cut evenly with 1 tbsp kosher salt, 1 tbsp black pepper, and 1 tbsp garlic powder.
Step 2: Place the brisket on the smoker rack fat side up and smoke for approximately 7 hours, maintaining 225°F until the internal temperature reaches 195°F and the meat is tender.
Step 3: While the brisket smokes, prepare pickled onions by combining 1 cup apple cider vinegar, 1 cup water, and 1 tbsp sugar in a small pot. Bring to a simmer until sugar dissolves, then pour over 1 medium thinly sliced red onion in a jar. Let sit at room temperature for at least 1 hour.
Step 4: Remove brisket from smoker and let rest for 20 minutes. Slice thinly against the grain.
Step 5: Toast 6 burger buns until golden brown. Spread 2 tbsp yellow mustard on each bun bottom, layer sliced brisket, drizzle 2 tbsp barbecue sauce, and top with pickled onions.
Step 6: Cover with bun tops and serve warm for a smoky, tangy brisket sandwich experience.
