Kellie’s Note
Souper Chicken Recipe
French onion chicken is basically like French onion soup, in main dish form. This recipe brings all the rich, savory flavor you love to tender, pan-fried chicken. If your family is bored of the same old chicken breast recipes, I can’t think of a better remedy than deeply caramelized onions and nutty gruyere cheese. (Try this Cheesy Spinach Stuffed Chicken Breast too!)
The key to this recipe is to really caramelize the onions. And that takes some time! But I’m gonna keep it real with you, I’m not going to be lie and tell you that you can caramelize the onions in 7 to 8 minutes. (Those are sautéed onions, friends, and don’t let anyone try to make you believe otherwise.)
The caramelized onions are sweet, jammy, and bring so much depth and flavor to this recipe. French onion chicken is decadent and indulgent in a way most other chicken dishes aren’t—and I wouldn’t have it any other way. This is the kind of recipe you serve to impress, whether it’s guests, your family, or yourself. If you love this chicken recipe, you need to try my French Onion Pork Chops
Why You’ll Love This French Onion Chicken
- French onion soup flavor in dinner form: Sweet caramelized onions, beef stock, herbs, Worcestershire, and Gruyere give this dish classic French onion flavor.
- No canned soup: This version builds the sauce from scratch for deeper flavor.
- Tender, juicy chicken: The chicken is seared first, then finished in the sauce so it stays moist.
- Perfect comfort food: Serve it over mashed potatoes, noodles, rice, or with crusty bread.
- Great for entertaining: It feels special but is made with simple ingredients
Ingredients for French Onion Chicken
- Chicken: Boneless skinless chicken breasts work best when sliced in half horizontally. For even cooking, aim for pieces that are similar in thickness. Boneless skinless chicken thighs can also be used, but they may need a few extra minutes to cook through.
- Onions: Sweet onions or yellow onions both work well. Slice them evenly so they soften and caramelize at the same rate.
- Gruyere cheese: Gruyere gives this recipe the most classic French onion soup flavor. Swiss, provolone, mozzarella, fontina, or gouda can be used if needed.
- Red wine: Use a dry red wine like Merlot, Pinot Noir, or Cabernet Sauvignon. To make it without wine, replace the wine with additional beef stock.
- Beef stock: Beef stock gives the sauce a deeper French onion soup flavor. Chicken stock can be used, but the sauce will taste lighter.
- Worcestershire sauce: Soy sauce or coconut aminos can be used instead for a similar savory flavor.
Best Onions for French Onion Chicken
Yellow onions and sweet onions are the best choices for French Onion Chicken. Yellow onions have a savory flavor that deepens as they cook, while sweet onions caramelize beautifully and add extra sweetness to the sauce.
For the best texture, slice the onions about 1/4 inch thick and keep the slices as even as possible. If the onions are too thick, they will take longer to soften. If they are too thin, they may burn before they become jammy and caramelized.
How to Make French Onion Chicken
- Prep the chicken: Pat the chicken dry and slice the breasts in half horizontally. Season and dredge in the flour-Parmesan mixture.
- Sear the chicken: Cook the chicken in olive oil and butter for about 3 minutes per side, just until golden. It does not need to be cooked through yet.
- Start the onions: Add butter and olive oil to the same skillet, scraping up the browned bits from the bottom of the pan.
- Caramelize the onions: Add the onions and cook until softened. Stir in the herbs and garlic, then cover and cook low and slow until the onions are sweet and jammy.
- Build the sauce: Add the wine and reduce by half. Stir in the flour, then add the beef stock and Worcestershire sauce. Simmer until slightly thickened.
- Bake with cheese: Return the chicken to the skillet, spoon the onions and sauce over the top, sprinkle with Gruyere, and bake until the cheese is melted and the chicken reaches 165°F.
- Serve: Garnish with fresh thyme and serve with mashed potatoes, noodles, rice, green beans, or crusty bread.
Kellie’s Tips for Making French Onion Chicken
These tips will help you make sure your French onion chicken turns out perfect.
- Swap out the wine. If you prefer not to use red wine, you can substitute it with more beef stock.
- Slice the onions to the same size. Thicker slices of onion won’t get as soft, so you want to make sure all of your onions are thinly and uniformly sliced. A mandoline slicer makes this easy if you have one.
- Don’t rush the onions. True caramelized onions need time. If the heat is too high, they can brown on the outside before they become soft and sweet.
- Use the browned bits. After searing the chicken, scrape up the browned bits from the bottom of the pan when you start the onions. They add a lot of flavor to the sauce.
- Watch the sauce thickness. The sauce should be glossy and spoonable, not watery. If it seems thin, simmer it for a few extra minutes before adding the chicken back to the skillet.
- Use a thermometer. Chicken is done when the thickest part reaches 165°F.
- Shred your own cheese. Freshly shredded Gruyere melts smoother than pre-shredded cheese.
- Use an oven-safe skillet. A cast iron skillet is perfect. If you’re not sure if your cookware is oven-safe, look in the manual or online. It’s better to be safe than sorry! And if you’re still not sure, just transfer the sauce and chicken to a casserole dish before baking.
French Onion Chicken Variations
- Creamy French Onion Chicken: Stir a splash of heavy cream into the sauce before adding the chicken back to the skillet.
- Mushroom French Onion Chicken: Add sliced mushrooms when the onions are nearly caramelized and cook until tender.
- No-Wine French Onion Chicken: Replace the red wine with additional beef stock.
- Chicken Thighs: Use boneless skinless chicken thighs instead of breasts and cook until they reach 165°F.
- Extra Cheesy: Add a mix of Gruyere and provolone or mozzarella for an extra melty topping.
- French Onion Soup Chicken Bake: Transfer the chicken and sauce to a baking dish before adding the cheese if your skillet is not oven-safe.
Storage, Freezing, and Reheating
- Store leftover French Onion Chicken in an airtight container in the refrigerator for up to 3 days.
- To reheat, warm the chicken gently in a covered skillet over medium-low heat or in a baking dish covered with foil at 325°F until heated through. Add a splash of beef stock if the sauce has thickened too much.
- The microwave works in a pinch, but it can make the chicken rubbery, so use short intervals and heat just until warmed through.
- To freeze, let the chicken and sauce cool completely, then store in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating. For best texture, add fresh cheese after reheating if possible.
What to Serve With French Onion Chicken

Equipment
- 1 oven safe skillet
Ingredients
Chicken
- 3 large boneless skinless chicken breasts, sliced in half horizontally
- 1 Tablespoon Italian seasoning
- ½ Tablespoon garlic powder
- 1 cup flour
- ¼ cup Parmesan cheese grated
- ½ teaspoon kosher salt
- 1/4 teaspoon black pepper
- 3 Tablespoons olive oil
- 1 Tablespoon butter
Sauce
- 2 Tablespoons butter
- 1 Tablespoon olive oil
- 4 cups thinly sliced sweet onions or other yellow onions, 1/4 inch thickness
- 1 teaspoon fresh chopped thyme
- 1 teaspoon fresh chopped rosemary
- 3 cloves garlic minced
- ½ cup red wine
- 2 Tablespoons flour
- 2 cups beef stock
- 1 tablespoon Worcestershire sauce, soy sauce or coconut aminos
- 2 cups shredded gruyere cheese, mozzarella, provolone, Swiss, cheddar, fontina, gouda can be substituted.
Instructions
Prepare the Chicken
- Pat the chicken dry and set aside. Whisk together the Italian seasoning, garlic powder, flour, cheese, salt and pepper.
- Dredge the chicken in the flour mixture shaking off the excess before moving to the next step.
- Heat 3 Tbsp. oil and 1 Tbsp. butter over medium-high heat. Add the chicken to the pan and cook the chicken for about 3 minutes on each side, until golden brown. Add a little additional olive oil as needed.
- Transfer the chicken to a platter and keep warm. The chicken does not need to be cooked all the way through at this point, it will finish cooking in the sauce.
Caramelize the Onions
- Melt the butter and olive oil over medium heat. Using a wooden spoon or spatula to scrape the brown bits from the bottom of the skillet, this adds more flavor to the sauce.
- Add the sliced onions and toss to coat. Cook for 5 minutes or until beginning to soften. Add the herbs and garlic.
- Cover and reduce heat to low. Cook for 30 minutes, stirring occasionally.
- Remove the lid and increase the heat to medium. Cook for 10 more minutes, stirring frequently.
Make the Sauce
- Preheat oven to 450˚F.
- Add the wine to the skillet. Cook uncovered until the wine is reduced by 1/2.
- Add flour and toss to coat. Cook for 1-2 minutes. Add the beef stock and increase the heat to medium-high bringing the sauce to a low boil. When the sauce begins to thicken, reduce the heat for 3-5 minutes. Remove from heat.
Bake
- Return the chicken back to the skillet and top with cheese. Bake at 450 for 15 or until the top begins to brown and is bubbling. Chicken is done when the thickest part reaches 165°F on an instant read thermometer.
- Remove from the oven and garnish with fresh thyme. Serve over egg noodles, rice or mashed potatoes.
Notes
- Chicken doneness: Chicken is fully cooked when the thickest part reaches 165°F on an instant-read thermometer.
- Wine substitute: Replace the red wine with additional beef stock if preferred.
- Cheese substitute: Gruyere gives the most classic French onion flavor, but Swiss, provolone, mozzarella, fontina, or gouda can also be used.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Freezing: Freeze cooled chicken and sauce in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating: Reheat gently in a covered skillet over medium-low heat or in a covered baking dish at 325°F. Add a splash of beef stock if needed.

I made this recipe. It was delicious and will make it again.
Thank you! I’m happy you liked it and appreciate the comment.
This French Onion Chicken recipe was phenomenal! I love a lot of sauce, so I doubled the sauce ingredients. The flavors in this recipe made us go crazy. My husband, who never complements my cooking, said the flavor was amazing. Normally, if he gets seconds, then I know he loves something I made, but for him to speak up was remarkable! This chicken was so tender. I served it over mashed potatoes but this sauce made the best onion gravy for those potatoes! Yum!!
I’m so happy you liked it! We love a lot of sauce, too, so doubling it was a good move.
