French Onion Chicken Bake
Those that love classic french onion soup, such as my Easy French Onion Soup recipe, will fall head over heals in love with this easy baked chicken dish.
I love simple chicken dinners, especially when it’s in casserole form like my Chicken Stuffing Bake.
Not only are they a true comfort food, but chicken casseroles like these fit so well into chaotic daily life.
One might think this would be the ideal recipe for fall, and it is.
Yet I made this recently, on a cool rainy summer day.
It was just the recipe to combat the gloominess.
This french onion smothered chicken recipe produces juicy and tender chicken breasts topped with caramelized onions.
Then glorious melted cheese is a blanket, both mozzarella and parmesan cheese.
It’s a taste that is really distinct and flavourful, it’s a favorite recipe. We’ve also taken a similar taste into a beef dish, French Onion Meatballs.
Best of all, you can serve this with pretty much any side dish like salad, Honey Glazed Carrots, and Oven Roasted Red Potatoes.
Since this is a perfect keto or low carb chicken dish, you can also serve these juicy chicken breasts alongside Roasted Garlic Cauliflower Mash. It’s a good choice.

How to Make French Onion Chicken Casserole:

- When onions are caramelized, place about 1/3 of the mixture into the bottom of the greased baking dish.

How to Caramelize Onions:
This French Onion Baked Chicken recipe includes a topping of beautiful sweet caramelized onion.
The buttery caramelized onions really makes the recipe, and ordinary sliced onions will not be the same. Here’s how to make them great:
- Sauté Onions In Butter Until Transparent and Soft: This first step is essential. Once they are soft, transparent and start to brown a little, they are done.
- Add Beef Broth and Balsamic Vinegar: This not only adds flavour but also stops the onions from drying out while they cook. In a pinch you can use chicken broth yet I’d prefer using beef.
- Garlic and Spices: More flavour is infused while the onions take on a sweet, jam-like consistency. Make sure to scrape up any of those browned bits from the onions when you stir.

Storage
Place chicken leftovers into an airtight container or cover with plastic wrap, and refrigerate for up to 5 days.
I like to reheat in a microwave-safe container, yet you can also bake in the oven to reheat completely.

What can I use in place of thyme, I have a friend that avoids this spice?
You can just leave it out if you wish!
Wouldn’t rosemary work? Chicken and rosemary, yum!
I sometimes use half olive oil and half butter and it works just fine although I haven’t tried it for this recipe.
I made it before and lived it ,,, Can I make ahead and freeze.?
I would totally make it, cooking and all – and then freeze. Make sure to thaw completely before reheating. Let me know how it turns out!
Does this freeze good?
Hola, I just answered that to Kay!
This was DELICIOUS!! Thank you!
My husband and I absolutely love this meal. However, this recipe is like three meals for us. Can I freeze any of this recipe for a later date so we are not eating this 3 days in a row?
Hi Kathy. I’m sorry to not have gotten back to you sooner. How did you make out with the leftovers?
My husband and I just finished eating this recipe and we both LOVED it. He said that this chicken recipe is one of the best I’ve made. Deff making this again. Thank you for sharing.
My daughter and I made this tonight and the whole house smelled amazing. And it was delicious Thank You
I made this but substituted a few things based on my health restrictions. Used boneless chicken thighs, glazed balsamic vinegar, poultry seasoning and vegan cheese. It smells so good! We enjoyed it too.
Hi Tammi… Can you substitute olive oil to carmelize the onions? Trying to avoid butter where possible.
I haven’t tried it, yet I do know many that use oil instead of butter to carmelize! 🙂
? Please .At any time is the chicken covered while cooking?
I don’t yet if the top is getting too crispy you can place some foil over top. It all depends on where your rack placement is.
I have alpha gal and can’t have anything to do with beef products what would you recommend instead of beef broth?
I would use chicken stock in this case.
Amazeing way to prepare chicken.. i had this at The Olde Hide House in Acton Ontario
Tried to duplicate it but used orange juice and soya sauce for that little of tart. Never thought to use balsamic vinegar glad i found this recipe
I’m glad you did as well! 🙂
I made this exact with glaze balsamic and I used a tbsp of the better than bouillon onion base in my onions. Perfect. Second time making it tonight !!
I made this tonight and my husband and I loved it. I made 4 thin sliced breasts, so we could have some leftovers. I added a small can of mushrooms also. It was done in about 25 minutes. I will be making this again, for us and or company, that’s how yummy it was. Thank you!!!
This was a BIG Hit tonight! My husband isn’t a onion fan so I was a little leery serving it. Turns out he Loved It & my 2yr old son did also! I only had 2 chicken breasts so I used 3 onions instead of 4 & I didn’t have shredded Parmesan so I used a little extra mozzarella & poured some Kraft Parmesan in. Thanks, this will be on rotation now!
Do you recommend chicken breasts, or can theey be replaced by thighs with this recipe?
I used boneless skinless chicken breasts, but you can totally use boneless skinless thighs too!
Is boneless chicken tenders just as good as breasts? Tenders are thinner
You can use those! 🙂
Second time in the making. I can get my chicken hateing family to eat this delicious recipe! Thank you.
It doesn’t matter. your preference. I use chicken thighs which was boneless and skinless
Delicious! I waited to add the cheese until ten minutes before the end of cooking time and it was perfect.
Just made this recipe as written. My family absolutely loved this meal!!!! It tasted amazing especially on this beautiful Fall day?. Thanks for sharing this great recipe. It’s a keeper!
This was really good! Instead of 2 T. off balsamic I used 1Tbsp of balsamic vinegar and 1 Tbsp of Red wine vinegar and I waited to add the cheese about 10 minutes before cooking was done. Very tasty! Thank you!
I just made this and it is yummy. It smells like onion soup in the house! Feels like autumn is there already… I roasted vetetables on a sheet pan with this. Simple to make and yet, very healthy and comforting. Thank you very much for this great idea. The bf loved it as well. 🙂

I made for dinner absolutely delicious. The only thing I need cut the salt back. Great recipe. My husband absolutely loved it
