Tender slow cooker BBQ beef sandwiches with a deep smoky flavor and quick homemade pickled onions that add a tangy crunch. Perfect for an easy, hearty meal with minimal prep.

Ingredients

Scale
  • 3 to 4 pounds beef chuck roast, trimmed of excess fat
  • 1 ½ cups BBQ sauce (store-bought or homemade)
  • ½ cup beef broth
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon smoked paprika
  • Salt and pepper to taste
  • 1 medium red onion, thinly sliced
  • ½ cup apple cider vinegar
  • ½ cup granulated sugar
  • 1 teaspoon salt
  • ½ teaspoon black peppercorns
  • Optional: pinch of red pepper flakes
  • Soft sandwich buns or brioche rolls

Instructions

  1. Pat dry the chuck roast and season generously with salt, pepper, onion powder, garlic powder, and smoked paprika.
  2. Place the seasoned roast in the slow cooker. Pour BBQ sauce and beef broth evenly over the top and spread around the sides.
  3. Cover and cook on low for 8 to 10 hours or on high for 5 to 6 hours, avoiding frequent lid opening.
  4. While the beef cooks, thinly slice the red onion. In a bowl, combine apple cider vinegar, sugar, salt, black peppercorns, and optional red pepper flakes. Stir until sugar dissolves, pour over onions, and let sit at room temperature for at least 30 minutes.
  5. Once the roast is fork-tender, remove it and shred the meat using two forks or tongs. Return shredded beef to the slow cooker and stir to coat with juices.
  6. Toast buns if desired. Assemble sandwiches by piling shredded beef on buns and topping with pickled onions.

Notes

For best tenderness, cook on low heat. Let beef rest 10 minutes before shredding to retain juices. If beef seems dry, add a splash of beef broth before serving. Pickled onions can be made ahead and stored refrigerated for up to 2 weeks. Use gluten-free buns or wraps for gluten-free option. Opening the slow cooker lid frequently extends cooking time.
