How to Make Easy One Pan French Onion Stuffed Chicken Recipe
Step 1: Caramelize the onions to golden perfection
Start by heating your cast iron skillet over medium heat then melting the butter. Add the thinly sliced onions along with fresh thyme, salt, and pepper. Stir them regularly, and be patient—the slow cooking brings out their natural sweetness. This usually takes about 20-25 minutes. You’ll know they’re ready when they’re soft, deeply golden, and smell irresistible.
Step 2: Prepare and stuff the chicken breasts
While the onions finish, combine your shredded mozzarella or gruyere with the parmesan cheese in a bowl. Once the onions are golden, scoop some together with the cheese and stuff it inside each butterflied chicken breast. Secure the openings with toothpicks so the filling stays put while cooking. It helps to press the filling down gently but don’t overfill!
Step 3: Brown the chicken for that beautiful crust
In the same skillet, add olive oil over medium-high heat and place the stuffed chicken breasts seam-side down first. Sear them for about 3-4 minutes on each side until they develop a nice golden crust. This step locks in flavor and creates an appetizing color.
Step 4: Bake with remaining onions and stock
Remove the chicken temporarily, add the remaining caramelized onions back into the skillet, and pour in the stock to deglaze the pan. Nestle the browned chicken breasts back into the skillet, tuck in a few fresh thyme sprigs, and transfer it to a preheated oven at 350°F (175°C). Bake for 20 minutes or until the chicken is fully cooked through and juices run clear.
Step 5: Rest and serve
Once out of the oven, let the chicken rest for 5 minutes—this keeps it juicy. Remove the toothpicks carefully, then plate each breast with the luscious onions and pan juices spooned over the top. Serve immediately and prepare to be amazed.
Pro Tips for Making Easy One Pan French Onion Stuffed Chicken Recipe
- Take Your Time on Onions: Don’t rush caramelizing—this is where you get that rich depth of flavor.
- Secure the Filling Well: Toothpicks are a must to keep the cheesy onions inside; double-tuck if needed.
- Use a Cast Iron Skillet: It helps brown the chicken evenly and can go from stovetop to oven seamlessly.
- Adjust Baking Time: Thicker chicken breasts may need extra minutes—always check that juices run clear.
How to Serve Easy One Pan French Onion Stuffed Chicken Recipe
Garnishes
I usually finish this dish with a simple sprinkle of fresh thyme leaves or a tiny drizzle of balsamic glaze to add brightness. It’s those little touches that make it feel extra special without much effort.
Side Dishes
My go-to sides include creamy mashed potatoes or wild rice pilaf that soak up the pan juices perfectly. Steamed green beans or a crisp side salad add a refreshing crunch to balance the richness.
Creative Ways to Present
For a special occasion, I like to slice the stuffed chicken into medallions and fan them out over a bed of caramelized onions and herbs. It makes for a beautiful presentation that gets guests talking!
Make Ahead and Storage
Storing Leftovers
Leftover chicken stores well in an airtight container in the fridge for up to 3 days. I recommend keeping the pan juices separate and pouring them warm over leftovers to revive that fresh-from-the-pan taste.
Freezing
I’ve frozen stuffed chicken before by wrapping each portion tightly in plastic wrap and then foil. When ready to eat, thaw overnight and reheat gently in the oven to preserve texture and flavor.
Reheating
Reheat leftovers in a 350°F oven for about 15 minutes, covered loosely with foil to avoid drying out. Reheat the onions separately in a pan, then spoon over the chicken for the best experience.
FAQs
-
Can I use chicken thighs instead of breasts for this recipe?
Absolutely! Boneless, skinless chicken thighs work well here and tend to remain juicier. Just adjust cooking times since thighs can be a bit thicker and fattier. Make sure to butterfly the thighs similarly to create a pocket for stuffing.
-
How do I know when the chicken is fully cooked?
The best way is to use a meat thermometer inserted into the thickest part of the chicken; it should read 165°F (74°C). Alternatively, you can cut into the chicken and check that juices run clear without any pink meat inside.
-
Can I make the caramelized onions ahead of time?
Yes! Caramelized onions keep well in the fridge for up to a week. Making them ahead saves time on busy days and enhances the flavors as they develop even further when stored.
-
What if I don’t have Gruyere cheese?
No worries—mozzarella and parmesan alone still deliver great flavor. You can also swap in Swiss or fontina cheese for a similar melty texture and mild nuttiness.

Description
This Easy One Pan French Onion Stuffed Chicken recipe combines tender, butterflied chicken breasts stuffed with a savory mix of caramelized onions and melted cheeses. Cooked in a single skillet with rich pan juices, this dish offers a comforting and flavorful meal perfect for weeknight dinners or special occasions.
Ingredients
For Caramelized Onions:
- 3 tablespoons butter
- 5-6 large onions, thinly sliced
- 1 teaspoon fresh thyme
- a pinch each of salt and pepper
For Chicken:
- 4 boneless, skinless chicken breasts, butterflied
- 1 cup shredded mozzarella or gruyere cheese
- 1/4 cup freshly grated parmesan cheese
- 2 tablespoons olive oil
- 1/3 cup chicken or beef stock
- a few sprigs of fresh thyme
Instructions
- Caramelize the Onions: Heat a large cast iron skillet over medium heat and melt the butter. Add the thinly sliced onions, fresh thyme, and a pinch of salt and pepper. Stir regularly and cook slowly until the onions turn a deep golden brown and develop a rich, sweet flavor, about 25 minutes.
- Prepare the Chicken: In a bowl, combine the shredded mozzarella or gruyere cheese with the grated parmesan. Carefully butterfly each chicken breast and stuff them evenly with the cheese mixture and a generous amount of the caramelized onions. Secure each stuffed chicken breast with toothpicks to keep the filling inside during cooking.
- Cook the Chicken: Preheat the oven to 350°F (175°C). In the same skillet used for the onions, heat olive oil over medium-high heat and brown the stuffed chicken breasts on both sides until golden, about 3-4 minutes per side. Remove the chicken from the skillet temporarily, add any remaining caramelized onions and the chicken or beef stock to the pan, stirring to combine and deglaze the skillet. Return the chicken breasts to the skillet, placing them on top of the onions and stock, and place the pan in the oven to bake for 20 minutes or until the chicken is cooked through.
- Serve: Remove the chicken from the oven and let it rest for a few minutes. Carefully remove the toothpicks, plate the stuffed chicken breasts, and spoon the onions and pan juices over the top. Serve immediately.
Notes
- Make sure to properly secure the filled chicken breasts with toothpicks to prevent the filling from spilling out during cooking.
- You can customize the cheese blend to your preference, using mozzarella, gruyere, or parmesan individually or combined.
- Adjust the baking time based on the thickness of the chicken breasts to ensure they are fully cooked and reach an internal temperature of 165°F (74°C).
