Servings 24 sliders


  • 3 yellow onions, sliced
  • 3 tablespoons olive oil
  • 24 King's Hawaiian rolls
  • 3 cups rotisserie chicken
  • 2 tablespoons plus 1 teaspoon BBQ seasoning, divided
  • 1/2 cup BBQ sauce
  • 8 large slices cheddar or pepper jack cheese (8 oz)
  • 1/4 cup butter, melted
  • Cooking spray


  • Heat a large nonstick skillet to medium-low heat. Add olive oil and onions. Cook, stirring occasionally, for 45 minutes to 1 hour or until very soft and brown.
  • Preheat oven to 375° F. Coat the bottom of a 9x13 baking dish with cooking spray.
  • Break rolls in half so that there are two sections of 12 rolls. While keeping rolls connected, slice each section in half horizontally using a large serrated knife. Place bottoms of rolls in prepared dish.
  • Place chicken in a bowl then add 2 tablespoons of BBQ seasoning. Toss to combine. Spread evenly over rolls in the pan. Drizzle 1/2 cup BBQ sauce over the chicken. Add caramelized onions evenly across the top. Add cheese slices then place tops of rolls on.
  • Add 1 teaspoon BBQ seasoning to the melted butter and stir. Brush tops of rolls with butter mixture. Cover with foil and place in oven for 10 minutes. Remove foil. Bake 5-10 more minutes until golden brown. Serve immediately.


  1. If onions start to get dry, add about 1 tablespoon of water to the pan.
  2. Optional: Add a teaspoon of sugar to the onions to speed up the process.
