1-Getting Started with Prep Work: First, pat the 3 boneless, skinless chicken breasts (about 2 lbs) dry and season them with 1 teaspoon coarse salt, 1 teaspoon ground black pepper, and 1 teaspoon garlic powder. Place them in the slow cooker for an easy start. While you’re at it, slice the jalapeño and measure out the other items like BBQ sauce and vinegar to keep things organized.

2-Mixing the Sauce: Next, combine 1 ½ cups BBQ sauce, 2 tablespoons apple cider vinegar, 1 tablespoon Worcestershire sauce, 1 teaspoon Italian seasoning, 2 tablespoons brown sugar, and ½ teaspoon crushed red pepper flakes in a bowl. Stir it all together until it’s well mixed, then pour it over the chicken in the slow cooker. This step infuses everything with that spicy, tangy goodness you’ll love.

3-Cooking and Shredding: Now, set your slow cooker to high and let it cook for 4 hours until the chicken shreds easily. Once it’s done, use two forks to pull the meat apart right in the pot. This keeps all those flavors locked in, making your spicy slow cooker BBQ chicken sandwich extra juicy. Keep an eye on it so it doesn’t overcook timing is key for perfect results.

4-Assembling Your Sandwich: After shredding, place a slice of pepper jack cheese on each of the 4 halved pretzel buns and toast them until the cheese melts and the buns turn golden. Add the shredded chicken on top and finish with the sliced jalapeño. It’s that simple! For more chicken inspiration, try our easy chicken tacos recipe.
