This French Onion Chicken skillet recipe is just as ooey, gooey, and cheesy as your favorite French onion soup but is packed with lean protein to keep you full. The best part is that it’s made in one skillet for easy cleanup and it’s ready in about 45 minutes!
One of my favorite things to do when I have time on the weekend is to go for a long drive with no destination in mind. We’ll find a small town and grab a meal at a local restaurant. We’ve found some real gems over the years!
I don’t have a typical order, and usually get whatever on the menu calls to me. But the one thing I can never seem to resist is French Onion soup. There’s just something about the rich broth, sweet onions, and gooey cheese that always hits the spot!
This French onion chicken skillet takes the best parts of French onion soup and transforms it into a simple yet filling weeknight dinner. That classic flavor always brings back so many memories!
But aside from being utterly delicious, it’s:
- Easy to cook;
- Freezer friendly, perfect for families on the go;
- A one-pot meal with minimal clean up;
- Full of cheesy goodness in every bite!
French Onion Chicken Skillet Ingredients
- Chicken Breasts. Boneless, skinless chicken breasts are the base of this recipe. Thinner breasts will cook faster. Mine here were HUGE so I split them crosswise before cooking.
- Chicken or Beef Broth. Your choice — use whatever you have on hand! I used chicken both this time because I had a carton open already.
- Fresh Thyme. I absolutely love the flavor of fresh thyme and think it’s non-negotiable when it comes to getting that classic onion soup flavor.
- Flour. Just a little bit, to thicken the broth.
- Yellow Onions.
- Baking Soda.
- Dijon Mustard.
- Gruyere Cheese.
How to Make French Onion Chicken
Start by browning your chicken breasts in a hot pan. Don’t worry about cooking them all the way through right now, since they’ll finish cooking in that delicious onion gravy. Right now, you just want to get some color on them. Transfer the chicken to a plate and save for later.
Next, caramelize your onions. This is the longest step of this recipe, but I shared some tips below that will help speed things up.
Once your onions are soft and jammy, add the flour and seasoning. Cook for a minute or two, then whisk in the broth.
Return the chicken to the pan and bring everything to a simmer until the chicken is cooked through. (Use a meat thermometer to get the perfect temperature and avoid overcooking)
Smother with the shredded cheese and pop the pan under the broiler for a few minutes until bubbling and browned.
How to caramelize onions quickly
Properly caramelizing onions can take a really long time, which I don’t usually have.
The secret to speeding things up? Add a pinch of baking soda to the pan!
This changes the Ph of the onions, helping them soften and brown more quickly. It also brings out their natural sweetness. Adding a splash of water to the pan during the first few minutes of cooking also helps the onions soften more quickly.
Pro-Tip: If you’re really impatient, you can also make a big batch of caramelized onions (I love this method for slow cooker caramelized onions) and freeze them for later. Then just pull some out when you want to make this chicken! You can cut about 10 minutes off the total cooking time.
FAQs
This skillet dinner is so versatile! It’s delicious with rice, quinoa, or farro; over mashed potatoes; or with a green vegetable. I love steaming green beans or broccoli in the microwave while the chicken is broiling. It’s so effortless!
Yes! Similar to chicken parmesan and other saucy recipes, these French onion chicken breasts freeze beautifully. To reheat, bake at 325F for 20 minutes, or until heated through.
Gruyere gives this recipe its classic flavor, but you can definitely swap in other good melting cheeses. I’ve made this with:
Provolone
Fontina
Mozzarella
They’re all delicious!
I’d avoid sharper Swiss cheeses, which lack creaminess and can overpower the other flavors in this recipe. They don’t typically melt well either.
Definitely!
I personally love boneless, skinless chicken thighs but I developed this recipe to be made with chicken breasts since I know they’re more popular.
If you want to use thighs, follow the same instructions but keep an eye on the cooking time since they’re generally smaller and cook faster than breasts do.
You’ll need a skillet that can go under the broiler. I recommend stainless steel or cast iron.
