How to Make French Onion Chicken Sliders

Caramelize Onions: In a skillet, melt butter over medium-low heat. Add sliced sweet onions and cook for 25-30 minutes until they’re beautifully golden brown. Stir occasionally and add a splash of water if they begin to stick.
Mix Chicken Filling: In a bowl, combine ground chicken with half of the chicken base, Worcestershire sauce, onion powder, garlic powder, salt, and pepper. Mix in the caramelized onions, then cook in the skillet over medium-high heat until the chicken is no longer pink. Drain off any excess grease.
Assemble Sliders: Preheat your oven to 350°F. Place the slider bottoms on a greased baking sheet. Spread the chicken mixture evenly over each bottom and generously sprinkle shredded Swiss or Gruyère cheese on top. Cap with the slider buns.
Prepare Butter Glaze: Melt any remaining butter and mix it with the leftover chicken base and Worcestershire sauce. Brush this mixture over the top of each bun and sprinkle with sesame seeds if desired.
Bake: Bake in the preheated oven for about 20 minutes, or until the cheese is melted and the tops of the buns are golden brown. Once out of the oven, let cool slightly before serving.

Optional: Serve with a dollop of your favorite dipping sauce for an extra flavor bomb!
