Before beginning the recipe, cook the 1 pound of chicken and shred it to your desired texture. Next, thinly slice the ½ cup red onion and sauté it using a small non-stick skillet until the onions are soft and translucent. The goal is to cook the onion until it no longer has the raw, hard texture. Once these steps are complete, set aside.
In a medium-sized bowl, stir together the prepared shredded chicken and 1 cup barbecue sauce until the chicken is fully coated in the sauce.
Top a sheet pan with the bottom half of the 12 slider buns. You can separate the slider buns or leave them connected together, either is fine. Spread the BBQ chicken evenly over each slider bun.
Drizzle ½ cup barbecue sauce over each bun. The sauce really gives this recipe all of the flavor, so don’t be afraid to use more if desired. The messier the better, it is BBQ after all.
Evenly layer the prepared red onion slices on top of the drizzled sauce.
Top the red onion with an even layer of the 7 ounces of thinly sliced smoked gouda cheese.
Add the top of the slider buns, cover the sheet pan with aluminum foil, and bake in the oven at 350 degrees F. for 15 minutes. While the chicken BBQ sliders are cooking in the oven, whisk together the 1 tablespoon butter, ¼ teaspoon salt, ½ teaspoon ground black pepper, and 1 tablesoon parsley.
Remove the sliders from the oven, remove the foil, and brush the top of each slider with the butter mixture. Place the sliders back into the oven to bake uncovered for 5 additional minutes until golden brown. Remove from the oven and serve warm. Enjoy!
