This French Onion Chicken transforms the classic soup into a hearty, comforting main dish. Juicy seared chicken is smothered in deeply caramelized onions, rich broth, and topped with melted cheese for a savory, restaurant-quality meal at home.
Ingredients (Servings: 4)
- 4 boneless, skinless chicken breasts
- 2 tablespoons olive oil
- 2 tablespoons butter
- 3 large onions, thinly sliced
- 3 cloves garlic, minced
- 1 teaspoon sugar
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon dried thyme
- 1 cup beef broth
- ½ cup dry white wine (optional)
- 1 tablespoon Worcestershire sauce
- 1½ cups shredded Gruyère or Swiss cheese
👨🍳 Instructions
1️⃣ Sear the chicken:
Season chicken with salt and pepper. Heat olive oil in a large skillet over medium-high heat. Sear chicken 4–5 minutes per side until golden brown. Remove and set aside.
2️⃣ Caramelize the onions:
In the same skillet, melt butter and add sliced onions. Cook over medium-low heat, stirring occasionally, for 20–25 minutes until deeply golden and caramelized. Add sugar and a pinch of salt to help the process.
3️⃣ Build the sauce:
Stir in garlic and thyme, cooking for 1 minute. Add white wine (if using) and scrape up browned bits. Pour in beef broth and Worcestershire sauce, then simmer for 5 minutes.
4️⃣ Combine and cook:
Return chicken to the skillet, nestling it into the onions. Spoon sauce over the top and simmer for 10–12 minutes until chicken is cooked through.
5️⃣ Add cheese and melt:
Sprinkle shredded Gruyère over the chicken. Cover and cook until melted, or place under a broiler for 2–3 minutes for a bubbly, golden top.
6️⃣ Serve:
Serve hot with extra onions and sauce spooned over the chicken. Great with mashed potatoes or crusty bread.
