FRENCH ONION BAKED CHICKEN
It’s no secret that I love comfort food, and french onion flavor is one of my all-time favorites. A few years back I combined french onion flavor with pork chops and it’s been a reader-favorite ever since!
The French Onion Smothered Pork Chop recipe doesn’t use traditional caramelized onions, and I knew I wanted to share a recipe that would use true caramelized onions, in all their jammy goodness!
Enticingly sweet and savory, this baked chicken recipe is absolutely amazing and so easy to make. The onions take a long time to cook, but they can be prepared days ahead of time.
HOW TO MAKE FRENCH ONION BAKED CHICKEN
- Caramelize the onions.
- Add part of the onions and beef broth to baking dish.
- Top with chicken breasts (raw).
- Top with remaining onions and cheese.
- Bake.
In terms of steps, it’s very simple! The hardest part is caramelizing the onions, and that’s really just a test of your patience.
COOKING TIPS FOR FRENCH ONION CHICKEN
- Don’t salt the onions – if you add salt right away to the onions, they’ll release their liquids too early and won’t caramelize properly.
- Be patient – I know, it’s hard for me too. Caramelized onions take time, plain and simple. There’s no secret way to instantly get gloriously brown and jammy onions. Trust me, it’s SO worth the wait! If you’re looking for a great visual representation of the stages of caramelizing onions, this is a great resource!
- Shred your own cheeses – it’s the best way to get amazingly gooey cheese.
- Get some crusty bread – there will be plenty of saucy onion broth after the chicken cooks, and there’s nothing better than soaking it up with amazing bread! We love this easy no-knead artisan bread.
VARIATIONS OF FRENCH ONION BAKED CHICKEN
- One Pan – if you have an oven-safe skillet, you can make this dish entirely in one pan! See the recipe notes section below (after the written recipe) for details.
- Seared – if you prefer, you can sear the chicken breasts before or after cooking the onions. This adds extra flavor, but isn’t necessary.
- Other protein – this recipe is fantastic with pork chops or even steak!
MAKING BAKED CHICKEN AHEAD OF TIME
I think this baked chicken recipe tastes best when made fresh, however, you can prep a couple things ahead of time to make the cooking time considerably shorter.
- Trim chicken breasts of any extra fat and keep refrigerated in an airtight container.
- Caramelize onions and garlic and keep refrigerated in an airtight container.
- Combine salt, pepper, thyme and garlic powder and keep on the counter in an airtight container.
This will cut your cook time in half, since the onions are already done!
STORING FRENCH ONION CHICKEN
Leftovers should be refrigerated and consumed within 2-3 days for best flavor.
Leftover caramelized onions should be refrigerated and consumed within 1-4 days. They can also be frozen, for up to 2 months.

This was a winner with my family! I used Tarragon in place of Thyme – don’t know how I ran out of that staple – and it was delicious. The time put into cooking the onions is the longest and I’ll try doing that ahead of time as the dish was a great combination of flavor and the chicken was tender and moist. I had really large chicken breasts so I cooked three instead of four and had to lengthen the time by 15 minutes to get them up to temperature. Thermometers make a difference!
Thanks for an alternative everyone enjoyed!
Jessica says
I have a household full of picky eaters and even the pickiest of the bunch enjoyed this. We’ve made it twice so far and it’s been great both times with my own little tweaks.
Julie says
This has become a sought after dish in my house, along with the stick of butter rice! Everyone loves it. I do add beef consommé and extra garlic to my sauce, and top with blend of Swiss and mozzarella, but either way is delicious
Steve says
This looks amazing, will the cheese burn before the chicken is done cooking?
The Chunky Chef says
I’ve never had an issue with the cheese burning, but if you’re worried, you could always cover it loosely with foil if you notice the cheese getting too golden for your liking.
Steve says
Thank you so much for this recipe, it was Amazing! one of my new favorite Chicken dishes, we will be making all the time!
Kyle says
This looks amazing! We cannot wait to try it as we love your other recipes, can this be made without balsamic vinegar, we do not have any? If so, is there a substitution you recommend?
Sam says
Can I use chicken broth instead of beef? My family can’t do beef broth.
The Chunky Chef says
Yes 🙂
Anna says
Very good! Followed the receipe exactly. Thank you for sharing. I will make again.
Christine says
I made this recipe for dinner tonight. I try new chicken recipes every week. My husband and I both thought this recipe was very good. It had a lot of flavor and was pretty easy to make. Also, it did not require a lot of ingredients.

Gr8!
Kim says
I absolutely love your recipes and this one was divine! So yummy served over mashed potato’s and the onions were so so good! Easy to make and a definite family pleaser. This might make it into the regular rotation for us. Thanks!
Melissa says
This was amazing!!!!
Bas says
I made it according to the directions with a longer baking time because the chicken breasts were huge. It was delicious. I served it over rice to absorb those delightful juices. Will make it again.
Dontay Lesser says
I can’t wait to make it and try it for myself
Raevenne says
I made this exactly as the recipe stated, and was really disappointed. I don’t know how your sauce and onions turned out so dark and lovely looking, but ours was really watery from the juices in the chicken, and the onions were nowhere near caramelized in that amount of cooking time, and just swam in this weak liquid at the end. This is definitely not something I’ll try making again.
Amanda says
Oh no, I’m sorry you didn’t have a good experience! This recipe will have a fair amount of juice in the pan, as any baked chicken recipe will, and you can see that in my photos. The onions are caramelized in a skillet before adding to the baking dish, so it sounds like our stovetops cook a bit differently. Unfortunately I can’t be in the kitchen with my readers, and I can’t account for every variance… I can only share what worked for me and my recipe testers. Best of luck to you in the future!
