- 4 boneless skinless chicken breasts: Perfectly lean protein that soaks up all the delicious flavors.
- 2 tablespoons olive oil: Helps caramelize the onions to golden perfection while adding richness.

- 1/2 teaspoon dried thyme: Brings aromatic earthiness to the layers of flavor.
- 1 cup low-sodium beef broth: Provides the savory, comforting base that soaks into the chicken and onions.
- 1 cup shredded Gruyère cheese (or Swiss cheese): Adds a nutty, melt-in-your-mouth cheesy topping.
- 1/2 cup shredded mozzarella cheese: Melts beautifully to create a bubbly, golden crust.

How to Make French Onion Chicken Bake Recipe
Step 1: Caramelize the Onions
Start by preheating your oven to 375°F (190°C). Heat olive oil in a large oven-safe skillet over medium heat. Add the thinly sliced onions and cook them slowly for 20 to 25 minutes, stirring often until they turn a deep golden-brown and become soft and sweet. This caramelizing process is the secret to the rich flavor that defines the French Onion Chicken Bake Recipe.
Step 2: Season and Simmer
Once the onions are perfectly caramelized, stir in the balsamic vinegar, salt, black pepper, garlic powder, and dried thyme. If you want a thicker, more velvety sauce, sprinkle the flour over the onions and mix well. Then pour in the beef broth and let everything simmer for 2 to 3 minutes, allowing the flavors to meld beautifully into a rich, savory base.
Step 3: Arrange Chicken and Bake
Gently nestle the chicken breasts into the onion mixture, spooning some of those luscious caramelized onions right on top of each piece. Cover the skillet tightly with foil and pop it into the oven. Bake for 25 minutes to let the chicken start absorbing all those wonderful flavors.
Step 4: Add the Cheese and Finish Baking
After 25 minutes, remove the foil and generously sprinkle the shredded Gruyère and mozzarella cheese over the chicken breasts. Return the dish to the oven uncovered and bake for an additional 10 to 15 minutes, or until the cheese is melted, bubbly, and golden, and the chicken is fully cooked through with an internal temperature of 165°F.
How to Serve French Onion Chicken Bake Recipe
Garnishes
Fresh thyme or parsley sprinkled over the top adds a pop of color and a hint of herbal brightness that complements the richness of the baked chicken and cheese.
Side Dishes
This French Onion Chicken Bake Recipe pairs beautifully with creamy mashed potatoes, fluffy rice, or a crusty baguette to soak up every ounce of that savory onion sauce. A simple green salad can also provide a crisp, refreshing contrast.
Creative Ways to Present
For an elegant touch, serve each chicken breast on a bed of garlic mashed cauliflower or roasted veggies. If you’re feeling playful, turn this into a casserole by layering the chicken and onions with slices of toasted baguette before adding the cheese.
Make Ahead and Storage
Storing Leftovers
Store any leftover French Onion Chicken Bake Recipe in an airtight container in the refrigerator for up to 3 days. The flavors tend to deepen after resting, making leftovers even more delicious.
Freezing
You can freeze the bake before adding cheese by cooling the caramelized onions and chicken mixture completely, then transferring it to a freezer-safe container. Freeze for up to 2 months. When ready, thaw overnight in the fridge and bake fresh with cheese to maintain that gooey topping.
Reheating
Reheat leftovers gently in the oven at 350°F for about 15 to 20 minutes, or until heated through. Cover the dish with foil to prevent the cheese from over-browning while warming.
FAQs
Can I use other types of cheese for this French Onion Chicken Bake Recipe?
Absolutely! While Gruyère adds a nutty richness, Swiss or provolone cheese are excellent alternatives that melt beautifully and complement the flavors just as well.
Is it necessary to use beef broth?
Beef broth lends that signature savory depth reminiscent of French onion soup, but you can substitute chicken broth if preferred, keeping the dish lighter yet still flavorful.
Can this recipe be made gluten-free?
Yes! Simply omit the all-purpose flour or use a gluten-free flour blend to thicken the sauce without compromising taste.
How do I know when the chicken is cooked through?
The internal temperature should reach 165°F. A meat thermometer is the best tool to ensure perfectly cooked, juicy chicken every time.
Can I use frozen chicken breasts?
It’s best to use fresh or fully thawed chicken breasts to ensure even cooking and proper absorption of the sauce flavors.

- 2 tablespoons olive oil
- 2 large yellow onions, thinly sliced

- 1/2 teaspoon garlic powder
- 1/2 teaspoon dried thyme
- 1 cup low-sodium beef broth

Garnish

Instructions
- Preheat the oven: Preheat your oven to 375°F (190°C) ensuring it’s ready for baking once your skillet is prepared.
- Caramelize the onions: In a large oven-safe skillet, heat the olive oil over medium heat. Add the thinly sliced onions and cook, stirring frequently, for about 20 to 25 minutes until they become soft and caramelized with a rich golden-brown color.

- Prepare the chicken: Nestle the chicken breasts directly into the onion mixture in the skillet, spooning some of the onions over the chicken to coat them evenly.
- Bake with foil: Cover the skillet tightly with aluminum foil and transfer it to the preheated oven. Bake for 25 minutes to cook the chicken through gently.
- Add cheese and finish baking: Remove the foil and evenly sprinkle the shredded Gruyère and mozzarella cheese over the chicken breasts. Return the skillet to the oven and bake uncovered for an additional 10 to 15 minutes until the cheese is melted, bubbly, and golden, and the chicken reaches an internal temperature of 165°F (74°C).
