French Onion Chicken Slider Ingredients
For the Sliders
- Ground Chicken – Forms the heart of the sliders; substitute with shredded rotisserie chicken for a quick alternative.

- Worcestershire Sauce – Infuses an umami punch; opt for a vegetarian version if making plant-based sliders.
- Slider Buns – The perfect vessel for your sliders; select whole wheat or gluten-free buns as a tasty alternative.

How to Make French Onion Chicken Sliders
- Caramelize Onions: In a skillet, melt butter over medium-low heat. Add sliced sweet onions and cook, stirring occasionally, for about 25-30 minutes until they turn golden brown and fragrant. If necessary, add a splash of water to prevent sticking.
- Prepare Chicken Mixture: In a bowl, mix ground chicken with Worcestershire sauce, onion powder, garlic powder, and half of the caramelized onions. Stir until well combined, then add to the skillet and cook over medium-high heat until no longer pink, about 5-7 minutes.
- Preheat Oven: While the chicken is cooking, preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Assemble Sliders: Place slider buns on the prepared baking sheet. Layer each bun with the chicken mixture, a generous amount of remaining caramelized onions, and a slice of gruyere cheese. Top with the bun lids.
- Butter Glaze: Melt any remaining butter and brush it over the tops of the buns. Add a sprinkle of sesame seeds and fresh thyme for extra flavor.
- Bake: Place the sliders in the preheated oven and bake for about 20 minutes or until the cheese is bubbly and the tops are golden brown.
- Cool & Serve: Allow the sliders to cool for a minute before serving warm for that perfect bite.
Optional: Serve with a side of tangy coleslaw for a refreshing contrast.

Expert Tips for French Onion Chicken Sliders
- Onion Perfection: Cook onions slowly over low heat to achieve that sweet, caramelized flavor—rushing can lead to burnt bits or bitterness.
- Grease Control: Be sure to drain excess grease from the chicken mixture before assembling to prevent soggy buns; no one wants a mushy slider!
- Cheese Variety: Experiment with different cheeses; while gruyere is classic, a blend of mozzarella and cheddar offers a deliciously melty alternative.
- Advance Prep: Consider caramelizing onions and cooking the chicken mixture a day ahead to save time; flavors deepen when they sit overnight!
- Slider Sizing: Choose bun sizes wisely—mini sliders are perfect for parties, but larger buns can double as hearty meals.
- Fun Toppings: For added flavor, experiment with toppings like caramelized peppers or fresh herbs, which complement the sliders’ rich essence beautifully.
