If you are looking for a fun way to jazz up your next weeknight chicken dinner, this Skillet French Onion Chicken with Mushrooms is easy and delicious to make!
This one-skillet dinner offers a fun twist on the beloved French Onion soup. Tender chicken breasts nestle in a French onion soup-inspired caramelized onion sauce that has mushrooms in it to add some veggies to this one-skillet dinner. The juicy chicken is then topped with gruyere cheese and baked to melty perfection. It’s the perfect protein-forward version of the classic soup!
Aside from the main items in the dish — the chicken, the onions, the mushrooms, and the cheese — the ingredient list remains pretty short. A few extra ingredients like the addition of Dijon, fresh thyme, and white wine amp up the dish, making it even more fabulous. The chicken is browned in the skillet before adding the additional layers of flavor, then it is transferred to the oven to finish roasting and to get the cheese nice and melty. I always love when dishes finish in the oven, giving me just enough time to tidy up the kitchen and set the table for dinner. So rich in flavor yet so easy to make!
As far as pairings go, this dish pairs well with so much! I like to serve mine with wild rice and a roasted vegetable this is in season, preferably Brussels sprouts, broccolini, or asparagus. You can also keep it simple and serve it with a side salad! You really cannot go wrong here.
Also, while photos show only 3 chicken breasts, there is definitely enough sauce for 4 chicken breasts depending on their size! I used three larger breasts here that equaled about 1 1/2 pounds, as listed in the recipe below.
I hope you and your family love this skillet chicken dinner as much as mine does!

Skillet French Onion Chicken with Mushrooms
Ingredients
- 4 boneless, skinless chicken breasts (about 1 1/2 pounds)
- 1 ½ teaspoon kosher salt
- ½ teaspoon freshly ground black pepper
- ½ teaspoon smoked paprika
- 1 ½ tbsp cassava flour
- 3 tablespoons extra virgin olive oil
- 1 small yellow onion halved and thinly sliced
- 8 ounces thinly sliced baby bella mushrooms
- 2 garlic cloves, minced
- 2 teaspoons dijon mustard
- 2 teaspoons fresh thyme leaves
- ½ cup dry white wine
- ¼ cup low-sodium beef or chicken broth
- ½ cup freshly grated gruyere cheese
Instructions
- Preheat the oven to 375F.
- Place the chicken breasts on a cutting board and cover with parchment paper or plastic wrap. Using a meat mallet or the bottom of a heavy skillet, pound the chicken until it is a uniform ½-inch thickness. Pat dry with paper towels.
- Season both sides of the chicken evenly with the salt, pepper and smoked paprika.
- Add the cassava flour to a shallow bowl and dredge both sides of the chicken into the flour so that it evenly coats all over. Shake off excess.
- Heat the oil in a large, oven safe skillet over medium-high heat. Add the chicken and cook until golden-brown on both sides, 2 to 3 minutes per side. Transfer the browned chicken to a clean plate and set aside.
- Reduce the heat to medium, add the onion, mushrooms and garlic and cook, stirring, until tender, 5 to 7 minutes.
- Stir in the dijon and fresh thyme until combined. While stirring, add the white wine and broth and stir until well combined.
- Nestle the chicken back into the skillet and top with the gruyere cheese. Transfer to the oven and bake until the chicken is cooked through and the cheese is lightly browned and bubbly, about 10 minutes.
- Remove from the oven, serve and enjoy!

Currently making this for the second time because we absolutely loved it the first! It tastes like it’s way more difficult to make than it actually is, which is the best kind of dish!
Agreed, my favorite type of meal! Thanks for commenting.
This was delicious!!! I followed the recipe to a T. If you love french onion soup, you’ll love this! I made homemade oven baked french fries as a side, and the extra sauce was so yummy with that too – kind of like a poutine. So good.
This was amazing. So good. My husband loved it. I omitted the wine and cheese to make it whole 30-compliant.
Awesome!!
Ma’am. You’ve outdone yourself with this one!
I’m late to the comment party but I finally made this for lunch today because I had some chicken that needed to be used. I am blown away by how easy and delicious it was…it’s like something I’d expect to have in a restaurant.
I subbed a few items based on what I had on hand, all-purpose flour instead of cassava, chicken bullion instead of broth, squeeze of lemon instead of white wine (because it’s the middle of a work day, lol) and Herbes de Provence instead of thyme, which really took it up a notch! I did not have any fresh mushrooms but will be running to the store to get some so I can repeat this dish ASAP! I also used thin-sliced chicken cutlets I had purchased at Sprouts, which made things easier. I know they usually cost a little more but it’s always worth it to me!
Bravo and my compliments to the chef!
I am so delighted that you love it!!! Thanks for sharing!
This looks really good and I want to make it. Unfortunately I do not have an oven safe skillet at the moment. Would it be fine to cook this meal stovetop?
What do you think of using chicken thighs instead of breasts?
Will be delicious with thighs!
Is this kid/toddler friendly? Asking because it has white wine? Is there a substitute for wine?? Thank you!
You can swap out the white wine for more beef broth! Cooking with wine + feeding your family is something you’ll have to research and determine if you feel comfortable/safe doing so.
Not to be dramatic, but this is one of the BEST meals I’ve ever cooked. I’d marry me.
The recipe calls for 1 1/2 tablespoons of flour, but in the video I saw on TikTok it looked like much more than that. Is it 1.5 TBS cassava flour?
1.5 tbsp of cassava is the correct amount! 🙂
That’s the same thing 😅
Alex this was SO incredibly good. I’m always amazed at how delicious and easy your meals are. I honestly prefer them to eating out! Thank you for another incredible meal
So yummy! Easy to make and delicious!!!
I normally don’t comment but I felt compelled to compliment you on this recipe. My wife and I have been cooking your dishes for a couple of years and you always hit it out of the park! Our kids really liked it too!
I subbed a bit more broth and about a tablespoon of champagne vinegar and it had a nice snap to it.
Why thank you so very much for taking the time to comment!! I really appreciate you and SO happy to hear it was a hit!
