The Full French Onion Chicken Bake Recipe
Ingredients
- 3–4 boneless skinless chicken breasts (about 8 ounces each)
- Kosher salt and fresh ground black pepper, to taste
- 1 tablespoon olive oil
- 3 tablespoons unsalted butter
- 2 large yellow onions, thinly sliced
- 3 sprigs fresh thyme
- 3 garlic cloves, minced
- 1 1/2 tablespoons all-purpose flour
- 1/4 cup white wine (No alcoholic drinks allowed, please substitute with a non-alcoholic option.)
- 1 cup low-sodium chicken broth
- 1/2 teaspoon Worcestershire sauce
- ~1 cup shredded Gruyère and/or Swiss cheese (optional)
Instructions
- Preheat your oven to 350°F (175°C).
- Season the chicken breasts with salt and pepper on both sides. In a large oven-safe skillet over medium-high heat, warm the olive oil. Brown the chicken breasts on both sides for about 4-5 minutes each. Remove the chicken from the pan and set aside. Tip: Make sure not to overcrowd the pan to achieve a nice golden brown.
- Reduce the heat to medium-low and add the butter to the same pan. Once melted, add the sliced onions and thyme sprigs with a pinch of salt. Cook the onions for about 20 minutes until soft and slightly golden. Remove the thyme sprigs. Cooking Tip: Stir the onions occasionally to prevent burning.
- Add the minced garlic to the pan and cook for another minute. Stir in the flour and cook for an additional minute. Pour in the white wine and cook for 2-3 minutes. Add the chicken broth and Worcestershire sauce, stirring until the sauce thickens slightly. Tip: If you prefer a thicker sauce, let it simmer a bit longer.
- Return the chicken to the pan, nestling it in the onion sauce. Transfer the skillet to the preheated oven and bake for 15-20 minutes until the chicken reaches an internal temperature of 165°F (74°C).
- Optional: Sprinkle the shredded cheese over the chicken during the last 5 minutes of baking for a bubbly, cheesy top.
- Let the chicken rest in the sauce for at least 5 minutes before serving. Slice the chicken and serve with the onion sauce. Serving Suggestion: This dish pairs wonderfully with rice, mashed potatoes, pasta, or steamed vegetables.
Serving Suggestions and Variations for French Onion Chicken Bake
This dish can be served over a bed of fluffy rice or creamy mashed potatoes to soak up the delicious onion sauce. For a healthier option, consider serving it alongside steamed broccoli or a fresh garden salad. If you’re feeling adventurous, try adding a splash of balsamic vinegar for a tangy twist or substituting the chicken with pork for a different flavor profile. For a lighter version, use a reduced-sodium chicken broth.
