Save This French Onion Chicken Bake is a comforting masterpiece that marries the savory depth of classic French onion soup with juicy, pan-seared chicken. Imagine tender chicken breasts nestled in a bed of sweet, jammy caramelized onions, all blanketed under a bubbling layer of rich Gruyere cheese. It is a sophisticated yet soulful dish that brings the elegance of a French bistro straight to your home kitchen.
Save The secret to the incredible flavor in this bake is the deglazing process. After the onions have been patiently caramelized to a deep mahogany hue, adding a splash of dry white wine helps release all the flavorful browned bits from the bottom of the pan. This creates a light, fragrant sauce that keeps the chicken incredibly moist as it finishes cooking in the oven.
Ingredients
- Chicken: 4 boneless, skinless chicken breasts, 1 teaspoon kosher salt, ½ teaspoon freshly ground black pepper, 1 tablespoon olive oil.
- Onions: 3 large yellow onions (thinly sliced), 2 tablespoons unsalted butter, 1 tablespoon olive oil, ½ teaspoon salt, 1 teaspoon sugar, 2 cloves garlic (minced), ½ teaspoon dried thyme, ¼ cup dry white wine (optional), ½ cup beef or chicken broth (gluten-free if needed).
- Topping: 1½ cups (about 150 g) Gruyere cheese (shredded), 2 tablespoons fresh parsley (optional).
Instructions
- Step 1: Prep and Sear the Chicken
- Preheat your oven to 375°F (190°C). Season the chicken breasts on both sides with salt and pepper. Heat 1 tablespoon of olive oil in a large ovenproof skillet over medium heat and sear the chicken for 2–3 minutes per side until golden. Remove the chicken and set aside.
- Step 2: Caramelize the Onions
- In the same skillet, melt the butter with the remaining olive oil. Add the sliced onions and salt, cooking and stirring for 15–20 minutes. Sprinkle sugar over the onions and continue to cook for 10 more minutes until they are deeply caramelized. Stir in the minced garlic and thyme, cooking for 1 minute.
- Step 3: Deglaze and Simmer
- Pour in the white wine (if using) to deglaze the pan, scraping the bottom to release the fond. Simmer until the liquid reduces by half, then stir in the broth and simmer for 2 minutes more.
- Step 4: Bake and Garnish
- Nestle the seared chicken back into the skillet and spoon some onions over the top. Sprinkle the shredded Gruyere evenly over the chicken and onions. Bake uncovered for 20–25 minutes until the chicken reaches 165°F (74°C). Let the dish rest for 5 minutes and garnish with fresh parsley before serving.
Zusatztipps für die Zubereitung
For the best results, use a high-quality ovenproof skillet and a sharp chef's knife for thin, uniform onion slices. If you want the cheese to be extra bubbly and brown, you can briefly place the skillet under the broiler for the last 1-2 minutes of cooking, but watch it closely to prevent burning.
Varianten und Anpassungen
This recipe is naturally gluten-free if you ensure your broth is certified gluten-free. If Gruyere is unavailable, Swiss or Emmental cheese are excellent substitutes that maintain the dish's French-inspired flavor profile. For an extra boost of savory umami, try adding a small splash of Worcestershire sauce when you stir in the broth.
Serviervorschläge
To make this a heartier meal, serve the chicken and onions over a bed of creamy mashed potatoes or alongside a stack of warm, crusty bread to soak up every drop of the onion-infused sauce. A crisp green salad with a sharp vinaigrette also helps to balance the richness of the melted cheese.
