Recipe Ingredients
Boneless Skinless Chicken Breast: you can easily swap the chicken breast for thighs if you’d like.
Olive Oil: this helps sauté the onions and forms the base of the sauce. Choose a great-tasting olive oil that you love.
Yellow Onions: I prefer the sweet flavor of yellow onions, but white onions will also work in a pinch.
Fresh Garlic: plenty of fresh garlic adds the perfect flavor to the sauce.
Chicken Broth: I like to use low-sodium chicken broth so that I can better control the amount of sodium in the dish. You could also swap veggie or beef broth if you prefer.
Arrowroot Starch: this is a grain free thickening agent that’s similar to cornstarch. It helps thicken the sauce so that it coats each piece of chicken.
Gruyère Cheese: one of the best parts of this recipe is the gooey melty cheese on top. If you can’t find Gruyère cheese, Swiss cheese is a great substitute.
How to Make This French Onion Chicken Recipe
Step One: Heat a large oven-safe braising pan with a lid over medium-high heat. Once hot, add 2 tablespoons of olive oil.
Step Two: Liberally season both sides of the chicken breasts with salt and pepper. Then, add the chicken to the skillet, and cook for 4 to 5 minutes on each side until the chicken is golden and cooked through. It should reach an internal temperature of 165 degrees!
Step Three: Remove the chicken from the pan, and reduce the heat to medium-low. Next, add the onions, and stir to coat them in the oil. Cover the pan with the lid, and let the onions cook for 20 to 30 minutes, stirring every 5 minutes or so until they’re golden brown.
Step Four: Add in the garlic, and cook for 1 minute. Be careful not to burn! Sprinkle the arrowroot starch over the onions, and stir to combine.
Step Five: Pour in the chicken broth, thyme, salt, and pepper. Stir until well combined. Then, increase the heat, and bring the sauce to a simmer. Let it simmer uncovered for 3 to 5 minutes or until it thickens slightly. Remove the pan from the heat.
Step Six: Add the chicken breast back to the pan, and spoon the onions and sauce on top. Top each chicken breast with a generous amount of shredded Gruyère cheese. Then, place it under a broiler just until the cheese is melted. Top with fresh thyme, and serve!
Side Dish Suggestions
I love to serve this French onion chicken recipe over mashed potatoes to soak up all the sauce. It’s also great with pasta, rice, or crispy smashed potatoes.
If you want to add a side, try pairing it with a refreshing salad, brown butter maple roasted carrots, or roasted garlic lemon broccoli.
How to Store, Freeze, and Reheat
Store: store any leftovers in an airtight container in the fridge for up to 3-4 days.
Freeze: let the French onion baked chicken cool completely. Then, transfer it to a freezer-safe container. Leftover chicken will stay fresh in the freezer for up to 3 months.
Reheat: to reheat leftovers, first let them thaw in the fridge overnight. Then, warm in the microwave or a skillet over medium heat until heated through.
