Ingredients

Instructions

  1. Step 1: Prepare quick pickled red onions by combining 1/2 cup apple cider vinegar, 1/2 cup water, and 1 tablespoon granulated sugar in a small saucepan. Heat over medium heat until sugar dissolves, about 3 minutes. Pour over 1 medium thinly sliced red onion in a jar and let cool to room temperature, then refrigerate for at least 30 minutes.
  2. Step 2: In a bowl, toss 1 lb boneless skinless chicken thighs with 1/2 cup BBQ sauce, 1 teaspoon smoked paprika, 1/4 teaspoon cayenne pepper, 1/2 teaspoon salt, and 1/4 teaspoon freshly ground black pepper until evenly coated.
  3. Step 3: Heat 1 tablespoon olive oil in a grill pan over medium-high heat. Cook chicken thighs for 5-6 minutes per side until internal temperature reaches 165°F and edges are slightly charred and smoky.
  4. Step 4: Let chicken rest for 5 minutes, then chop into bite-sized pieces and toss again with any remaining BBQ sauce.
  5. Step 5: Assemble sliders by placing chopped chicken on 8 mini slider buns, topping with pickled red onions, and closing with the bun tops. Serve immediately for a spicy, tangy bite.
