French Onion Chicken Ingredients
• Gather everything you need for a flavorful feast!
For the Chicken
- Chicken breasts – choose boneless, skinless for easy cooking and a tender bite.
- Kosher salt – enhances the chicken’s natural flavors; adjust to your taste.
- Black pepper – freshly cracked adds warmth and depth to the seasoning.
For the Onions
- Unsalted butter or olive oil – both work beautifully; butter offers a rich flavor, while olive oil adds a healthier twist.
- Sweet yellow onions – their natural sweetness caramelizes beautifully, resulting in a rich sauce.
- Garlic – fresh minced garlic brings aromatic flavors that elevate the dish.
- Fresh chopped thyme – a fragrant herb that complements the richness of the onions.
- Red chili flakes (optional) – add a pinch for a zesty kick to the dish!
For the Sauce
- Dry white wine or chicken broth – use for deglazing the pan and intensifying the flavors; chicken broth is a great substitution if avoiding alcohol.
- Cornstarch or tapioca flour – acts as a thickener to give your sauce a luxurious consistency.
- Chicken broth – enriches the overall flavor profile of your French Onion Chicken.
For Topping
- Shredded gruyere, mozzarella, or white cheddar cheese – these cheeses melt beautifully, adding creaminess and richness on top.
- Sliced sourdough or French baguette (optional) – perfect for soaking up the luscious sauce and completing your meal!
How to Make French Onion Chicken
- Preheat: Start by preheating your oven to 400°F (200°C). This will ensure your French Onion Chicken bakes evenly to perfection.
- Prepare the Chicken: Pat the chicken breasts dry using a paper towel to remove excess moisture. Pound them to an even thickness to ensure that they cook uniformly. Season both sides generously with kosher salt and black pepper.
- Sear the Chicken: In a large, oven-safe skillet, melt 1 tablespoon of butter or olive oil over medium-high heat. Once hot, add the chicken breasts and sear for about 2 minutes on each side until golden brown. Remove them to a clean plate to rest.
- Cook the Onions: Turn down the heat to medium and add the rest of the butter or oil (3 tablespoons). Toss in the thinly sliced onions, cooking for about 5 minutes. Pour in a splash of white wine or chicken broth and keep stirring until the alcohol evaporates. Then, let the onions cook for another 10 minutes until they’ve turned a lovely golden hue.
- Add Flavor: Toss in the minced garlic, fresh thyme, and optional red chili flakes, stirring frequently for another 5-10 minutes. You want the onions to be deeply caramelized and incredibly fragrant, so keep an eye on them!
- Thicken the Sauce: In a separate bowl, mix the cornstarch with the chicken broth, ensuring there are no lumps. Pour this mixture over the caramelized onions, letting it simmer until it thickens slightly and reaches a jam-like consistency.
- Nestle the Chicken: Remove the pan from the heat and return the seared chicken breasts to the pan. Burrow them into the luscious onions, and ladle any remaining caramelized onions on top.
- Add Cheese and Bake: Generously sprinkle shredded cheese over each chicken breast. Bake in the preheated oven for 6-8 minutes, until the chicken reaches an internal temperature of just below 165°F and the cheese is beautifully melted and bubbling. If you love a crispy cheese top, broil for an additional 1-2 minutes.
- Garnish and Serve: Remove from the oven and garnish with fresh thyme or chopped parsley for an added touch of color. Serve alongside the extra sauce and onions your taste buds will thank you!
Optional: Pair with crusty bread for the ultimate comfort food experience.

Tips for the Best French Onion Chicken
Use Fresh Onions: Fresh, sweet yellow onions caramelize better than older ones, giving your French Onion Chicken an incredible depth of flavor.
Watch the Heat: Cooking onions patiently over medium heat allows them to caramelize properly. If the heat is too high, they’ll burn instead of caramelizing.
Don’t Skip the Wine: Using dry white wine adds complexity to the dish; however, chicken broth works great for a non-alcoholic version. Just remember to deglaze for extra flavor!
Thickening Consistency: Be sure to mix cornstarch with the chicken broth until smooth before adding it prevents clumps in your sauce for that luxurious texture.
Check Chicken Temperature: Avoid overcooking by checking the internal temperature; 165°F is perfect for juicy chicken every time.
Cheese Choices Matter: Gruyere offers traditional taste, but mozzarella or white cheddar melts beautifully too. Choose what you love for a personalized touch!

Make Ahead Options
These French Onion Chicken Bake preparations will save you precious time on busy weeknights! You can slice the onions and marinate the chicken breasts in salt, pepper, and a splash of wine or broth up to 24 hours in advance, keeping them refrigerated to lock in flavor. Additionally, caramelizing the onions can be done a day ahead; just store them in an airtight container to prevent them from drying out. When you’re ready to bake, simply reheat the onion mixture briefly, then nestle the marinated chicken back in, top with cheese, and bake as instructed. This way, you’ll have a delectable and comforting meal ready with minimal effort!
How to Store and Freeze French Onion Chicken
Fridge: Store leftover French Onion Chicken in an airtight container for up to 3 days. This will keep the chicken tender and the flavors intact.
Freezer: For longer storage, freeze the cooled chicken in airtight containers for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating: To reheat, place in a preheated oven at 350°F (175°C) until warmed through, about 20 minutes. This retains the creamy texture and melted cheese topping beautifully.
Assembly Tip: If freezing, consider storing the sauce separately to keep it fresh; combine right before reheating for the best taste!
French Onion Chicken Recipe FAQs

How should I store leftover French Onion Chicken?
Very easy! Store any leftovers in an airtight container in the refrigerator for up to 3 days. Just be sure to allow the dish to cool completely before sealing it to preserve its tenderness and flavor. When you’re ready to enjoy it again, gently reheat in the oven for the best results.
Can I freeze French Onion Chicken?
Of course! To freeze your French Onion Chicken, allow it to cool completely before placing it in airtight containers or freezer bags. It will keep well for up to 3 months.
