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, stirring occasionally until they’re beautifully caramelized and golden brown. Add a splash of water if they begin to stick.
Mix Chicken Ingredients: In a mixing bowl, combine ground chicken with half of the beef base, Worcestershire sauce, salt, and pepper. Mix well, ensuring everything is evenly incorporated.
Combine with Onions: Add the seasoned ground chicken to the skillet with caramelized onions. Cook on medium heat, breaking the chicken apart as it browns, until fully cooked through (about 7-10 minutes).
Preheat Oven: Set your oven to 350°F (175°C) and lightly grease a large baking sheet to prevent sticking.
Assemble Sliders: Line the baking sheet with slider buns; scoop the chicken mixture generously onto the bottoms, top with Gruyère cheese slices, and then place the tops of the buns.
Add Butter Mixture: In a small saucepan, melt remaining butter and mix in Worcestershire sauce. Brush this blend over the tops of the buns, then sprinkle with sesame seeds and fresh thyme for extra flavor and crunch.
Bake: Place the assembled sliders in the preheated oven and bake for about 20 minutes, or until the buns are golden brown and the cheese is nicely melted.
Serve: Let the sliders cool for a few minutes before slicing into them for easier serving. Enjoy the comforting flavors of your freshly made French Onion Chicken Sliders!

Optional: Serve with a side of tangy pickles for a delightful crunch.
