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 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.
What to Serve with French Onion Chicken:

To align with this keto chicken dish, try this Roasted Garlic Cauliflower Mash or cauliflower rice.

Yet this is a great recipe to pair these Baking Powder Biscuits with.
Of course this chicken dish is wonderful with white wine to drink.
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.

Hi! Can you substitute butter if dairy free? Do you have a suggestion? Thanks!
Hello, I haven’t tried a substitute for this. Maybe someone has a suggestion and can comment.
Did anyone use Swiss cheese to top the chicken?
Wow! I made this last night. Fairly easy recipe with ingredients that I keep in my kitchen. I used boneless, skinless, chicken thighs. This was delicious. My husband was “wowed” too! Thanks for giving us a great way to prepare chicken.
I made this tonight and it was INCREDIBLE. I’m already thinking of the guests I want to make this for soon! My husband sounded like Bill Murray in “What about Bob” while eating it ?
haha, love that! 🙂
Never seen a site like this. Can’t see all the ingredients!! I don’t have time for this
EVERY blog has a recipe card, like this one. How can you not see it?
Thank you so much for sharing this great recipe! My ma’s an *extremely* picky eater with some dietary restrictions and it makes finding recipes she’ll enjoy incredibly difficult. I made this and managed to persuade her to try a little before she headed out to work. Before she was even able to get out her rare positive review – I already knew from the look on her face it was a hit! Thank you, thank you, thank you! ❤
I carmelized the onions for an extra 20 minutes at the beginning to really get that rich French onion flavor and added extra cheese at the end (Can you ever have too much cheese?) but other than that I followed the recipe as written. It was out of this world! My whole family devoured it. Will definitely be making again
Amazing!
Will it taste similar if I substitute the mozzarella with Cheddar cheese? Thank you
I swap for this sometimes. I love mozza on this but in a pinch I’d do it.
YUM! This would be great for changing up plain old chicken dinners.
I have had this pinned for quite sometime. Wishing now I had made it sooner. This was a delicious meal. The only thing did different was I used chicken bouillon vs beef, per the recipe. This recipe will definitely be going on my rotation. When the hubby and daughter devour a meal, it is a definite must for the rotation. Thank you so much, Tammi, for the great recipe.
OMG! This is DELICIOUS!!! ?? Hubby called it a grand slam & wants it in regular rotation! I added a dash of red wine, dash of Worcestershire sauce and served it w/rice & fresh green beans. Yum! (I also had some wedges of Laughing Cow light Swiss/garlic cheese, and added those in place of some of the mozzarella.)
I made this tonight and it was delicious! The chicken was so tender and flavorful. I sprinkled some poultry seasoning on the chicken before topping with the onions and cheese and I didn’t salt as figured the broth was adding enough salt. I love French onion soup and this recipe is a keeper . Thank you for sharing!
Just tried this and it truly is an amazing recipe! Thanks so much!
Do you bake this covered or uncovered?
I bake uncovered personally
Hi I made it, no covering needed.
I made this last night. It really is good! The beef broth is necessary for the French Onion Soup flavor. I had a leftover leek and 3 shallots and just added them to the onions. The only thing we will change next time is cutting down the amount of thyme. It is definitely needed for the flavor but it seemed to overpower the subtle yumminess of the caramelized onions. Will definitely make it again!
YAY!
Can you use chicken broth instead of beef broth? I don’t eat beef.
Sure!
