Ingredients

Scale
  • 5 lbs beef brisket, trimmed of excess fat (USDA Choice recommended)
  • 2 tbsp kosher salt
  • 2 tbsp coarsely ground black pepper
  • 2 tbsp smoked paprika
  • 1 tbsp garlic powder
  • 1 tbsp onion powder
  • 1/2 cup beef broth or water (for spritzing during smoking)
  • 1 large red onion, thinly sliced
  • 1/2 cup apple cider vinegar
  • 1/2 cup water
  • 1 tbsp sugar
  • 1 tsp kosher salt
  • 1/2 tsp black peppercorns
  • Pinch of red pepper flakes (optional)
  • 1/2 cup mayonnaise
  • 2 tbsp ketchup
  • 1 tbsp prepared horseradish
  • 1 tsp smoked paprika
  • 1 tsp Worcestershire sauce
  • 1 tsp hot sauce (like Tabasco)
  • 1 tsp lemon juice
  • Salt and pepper to taste
  • 12 slider buns, lightly toasted (brioche buns recommended)
  • Optional: fresh arugula or pickles for extra crunch

Instructions

  1. Prepare the brisket rub by combining kosher salt, black pepper, smoked paprika, garlic powder, and onion powder in a small bowl.
  2. Pat the brisket dry with paper towels and rub the spice mixture evenly all over the meat. Let rest at room temperature for 30 minutes.
  3. Preheat the smoker to 225°F (107°C) and place soaked wood chips (hickory or oak) for smoke aroma.
  4. Place the brisket fat side up on the smoker rack once steady smoke appears.
  5. Insert a meat thermometer into the thickest part of the brisket and smoke for 6-8 hours, spritzing with beef broth or water every hour to keep moist.
  6. Smoke until the internal temperature reaches 195°F (90°C) for tender, pull-apart brisket.
  7. Remove the brisket and wrap loosely in foil or butcher paper. Let rest for at least 1 hour to redistribute juices.
  8. Make the pickled onions by heating apple cider vinegar, water, sugar, salt, peppercorns, and red pepper flakes in a small saucepan until sugar dissolves.
  9. Pour the hot pickling liquid over sliced onions in a jar or bowl. Let cool and refrigerate for at least 1 hour.
  10. Prepare the comeback sauce by whisking together mayonnaise, ketchup, horseradish, smoked paprika, Worcestershire sauce, hot sauce, lemon juice, salt, and pepper. Refrigerate until ready to use.
  11. Slice the rested brisket thinly against the grain.
  12. Assemble sliders by spreading comeback sauce on the bottom half of toasted buns, adding brisket slices, topping with pickled onions, and finishing with the bun tops.
  13. Add arugula or pickles if desired.

Notes

If you don’t have a smoker, use a charcoal grill with wood chips or cook the brisket low and slow in the oven at 250°F wrapped in foil. Slice brisket against the grain for tenderness. Spritz brisket lightly every hour to keep moist but avoid washing away the rub. Pickled onions can be made a day ahead for more tang. Toast buns lightly to prevent sogginess. For gluten-free, use gluten-free buns or lettuce wraps; for dairy-free, use vegan mayo in the comeback sauce.
