These chicken sliders are topped with garlic butter and baked until golden and oozing with melted cheese, tender chicken, red onion, and BBQ sauce.
Gather all ingredients. Preheat the oven to 350 degrees F (175 degrees C).
Place roll bottoms on a baking sheet. Divide chicken, Cheddar cheese, BBQ sauce, onion, and parsley equally over rolls.
Cover with roll tops; brush with melted butter. Sprinkle Parmesan cheese and garlic on top.
Bake in the preheated oven until golden brown and cheese is melted, about 20 minutes. Slice and serve.
Enjoy!
