If there’s one soup that gets a lot of love it has to be french onion soup. It’s legit on every restaurant menu in America. Dare I say it might be more popular than chicken noodle soup? Ok, ok that might be taking it too far. Anyway, French onion soup is loved by a lot of people, especially me and so I decided to take the classic soup recipe for a spin by making it into a chicken dish. You guys know how much I love chicken and I love nothing more than recreating traditional recipes into something new. By taking some key elements of the French onion soup and tweaking them a bit for this dish, I came up with the most delicious, mouth-watering dish that makes everyone at the dinner table happy and satisfied. This recipe is good ya’ll. I have no idea why it took me so long to share it on the blog officially but I’m glad I’m doing it now so that it can be here for years to come. If you are a French onion soup lover and want to enjoy those traditional flavors you have to take this recipe for a spin.

Ingredients for my french onion chicken skillet recipe:

To season chicken thighs:
Bone-in chicken thighs
salt, pepper, onion powder, garlic powder, Italian seasoning

For caramelized onions:
Vidalia onions thinly sliced
Dry thyme
Kosher salt
Olive oil

For sauce:
Chicken broth
Heavy cream
Chopped parsley
Kosher salt and pepper to taste
Splash of dry white wine such as pinot grigio or a dry rose *optional

To finish the dish:
Shredded Gruyere cheese..sub with white cheddar if needed
sprinkle of fresh parsley

Tools you’ll need:
Cast iron skillet

Can I use boneless chicken?

Yes, you can but be careful not to dry the chicken out, monitor the internal temperature, and remove it from the oven as soon as it hits 165. Dark meat retains more moisture and I find it to be more complimentary to this dish.

Can I use any white cheese for the topping?

You can but to get that traditional flavor you find in Fench onion soup you want to use Gruyere cheese.

Can I use any type of onions?
I would suggest white onions as they get sweeter the longer you cook them and that works well here for the caramelization process.

Why does it take so long to carmelize onions?
Enough moisture has to evaporate from the pan to allow the onions to start to release natural sugars, which will then cause the onions to change colors and caramelize. In order for this to happen, you have to monitor the heat of the pan and be sure you aren’t causing the onions to burn. Doing it on a low steady heat will yield the best result. According to if you’re in a hurry, you can speed up the process a little by adding a pinch of sugar, which kick-starts caramelization, or baking soda, which breaks down the onions’ cell walls faster so you can simmer out more moisture.

    Delicious Keyo friendly chicken worthy of a 5* restaurant. I served it with cauliflower rice cooked with roasted garlic. This is a keeper. Our first Keto meal. I am certain it will be put in rotation.
