- 4 –6 bone-in or boneless chicken thighs or breasts
- 3 large yellow onions thinly sliced
- 3 tbsp butter
- 1 tbsp olive oil
- 3 garlic cloves minced
- 1 tsp fresh thyme or ½ tsp dried
- 1 bay leaf
- 1 cup beef broth or chicken broth
- ½ cup dry white wine optional but recommended
- 1 tbsp Worcestershire sauce
- Salt and black pepper to taste
- 1 tsp sugar helps caramelize onions
- 1½ cups shredded Gruyère cheese

Caramelize the onions
Heat butter and olive oil in a large skillet over medium-low heat. Add sliced onions, salt, and sugar. Cook slowly for 25–35 minutes, stirring often until golden brown and soft.
Add flavor base
Stir in garlic and thyme. Cook for 1–2 minutes until fragrant.
Deglaze the pan
Pour in white wine (if using) and scrape up browned bits. Let reduce for 2–3 minutes.
Add broth & seasoning
Stir in beef broth, Worcestershire sauce, and bay leaf. Simmer for 5 minutes.
Brown the chicken
Season chicken with salt and pepper. In a separate pan (or push onions aside), sear chicken for 2–3 minutes per side until lightly golden.
Braise
Nestle chicken into the onion mixture. Cover and transfer to a preheated oven at 375°F (190°C). Bake for 25–35 minutes until chicken is fully cooked.
Add cheese
Sprinkle Gruyère over the top and broil for 2–4 minutes until melted and bubbly.
Serve
Garnish with parsley and serve hot.
- For extra richness, add a splash of cream to the onion sauce.
- Gruyère can be substituted with Swiss or mozzarella, but Gruyère gives the most
- authentic French onion flavor.
- Best served with toasted baguette, mashed potatoes, or rice.
