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:

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:

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.

Love this recipe and have made it several times. Has anyone tried it with pork chops? Was wondering if the chops should be browned first.
If you’d like to, you could. Yet I also have a French Onion Pork Chops recipe posted as well. 🙂
I was looking for something refreshing to make and luckily came across this recipe of fresh onion and chicken bake. Delectable and creamy, this is perfect for my kids and in fact, they loved it. I made it when I had some guests at my place and they appreciated it too.
The recipe of French onion chicken bake is definitely a must-have during a cheerful Sunday brunch. I recommended it to my friends as well. I am surely going to make it again because my kids are pestering me for it everyday. The sweet caramelized onions drizzled all over the cheesy parmesan baked chicken tasted so good!
This recipe was delicious. I added 1 packet of liption onion soup to the onion mixture. Next time I would cut the chicken breast so they were thinner and would double the recipe. The cheese on top is SO good. I will add more cheese when I make it again.
Good addition! 🙂
With the summer season getting out of hand and a couple of guests coming over during the weekend, I was looking for something easy and delicious when this recipe came to my rescue of gooey French onions and cheesy chicken bake. Everyone was happy and content at the table.
This turned out great! Made a few tweaks due to my hubby’s low sodium diet and it was still really good. This was so easy and def a keeper!
This recipe was delicious. I tried this, and my mom just loved it. Thanks for sharing.
How many pounds of chicken breasts do you use? This recipe is AWESOME! My girls didn’t like onions and now they love them. Thank you!!
I always go with the number of breasts and don’t actually notice the weight. Haha.
Is the balsamic vinegar a glaze?!
no it is a type of vinegar
This recipe has been a family favorite since we tried it. The cheese we use varies, but we prefer provolone. I must admit, I also cheat and use a can of french onion soup in place of the beef broth. Comes out fantastic!
Me too!!
My husband’s birthday is coming up & I always make him something he loves. Usually it’s a boring chicken parmigiana! Ugh! But I suggested the French onion chicken & he was thrilled that I’m making this dish again!
Thanks for this delicious recipe! It’s in my favorites on Pinterest!
I made it and used Gruyère cheese and parm. Everyone enjoyed it so it will be on my list more often.
Delicious recipe and easy! I only had thin sliced chicken breasts at my grocery store. If this is you also, can reduce cook time by about 5 minutes or so. I’m definitely going to try reg size chicken breast’s next time as I can’t wait to make this again! Thanks for the recipe!
I don’t understand why 15g of carbs
Oh it’s not. I think it’s a glitch in the card itself. Darn technology.
I made this for dinner tonight and it was absolutely delicious!!
I used gouda instead of mozza and gave it an added depth of flavour, thank you, I will definitely be making this again.
