How to Make French Onion Stuffed Chicken

Step 1: Caramelize the Onions

Start by thinly slicing the yellow onions and cooking them low and slow in a mixture of butter and olive oil. Stir frequently until they turn a deep golden brown and sweetly fragrant, which usually takes about 15 to 20 minutes.

Step 2: Prepare the Chicken Breasts

While the onions caramelize, carefully slice a pocket into each chicken breast without cutting all the way through, creating space to stuff the filling. Lightly season the chicken inside and out with salt and pepper.

Step 3: Stuff the Chicken

Once the onions are ready and slightly cooled, mix them with shredded Gruyere cheese and fresh thyme. Spoon this mixture evenly into each chicken breast pocket. Secure the openings with toothpicks or kitchen twine to hold the filling in place during cooking.

Step 4: Cook the Chicken

Heat a skillet over medium-high heat with a little olive oil and sear each stuffed chicken breast for 3-4 minutes on each side until golden brown. Then, transfer the skillet to a preheated oven at 375°F (190°C) and bake for 15 minutes more, or until the chicken is fully cooked and cheese is melted inside.

Step 5: Rest and Serve

Allow the chicken to rest for 5 minutes after baking to keep the juices locked in. Remove the toothpicks or twine, slice if desired, and plate it with your chosen sides.

Pro Tips for Making French Onion Stuffed Chicken

• Properly caramelize onions: Patience is key; don’t rush or increase heat too much to avoid burning and bitterness.
• Slice chicken carefully: Use a sharp knife to create a pouch without cutting all the way through, preventing leaks.
• Secure the filling: Toothpicks work great, but kitchen twine ensures a tighter seal during cooking.
• Use a meat thermometer: To guarantee perfectly cooked chicken, aim for an internal temperature of 165°F (74°C).
• Let it rest: Resting the chicken after cooking lets the juices redistribute, making the meat juicy and tender.

How to Serve French Onion Stuffed Chicken

Garnishes

Fresh thyme sprigs or a light sprinkle of chopped parsley add a wonderful burst of color and subtle herbal freshness that complements the rich stuffing perfectly.

Side Dishes

Serve with creamy mashed potatoes, a crisp green salad, or roasted asparagus to balance the meal with fresh, crisp, or velvety textures.

Creative Ways to Present

Slice the stuffed chicken diagonally for a beautiful reveal of the cheesy onion filling, and drizzle a simple pan sauce made from the skillet drippings for an elegant touch.

Make Ahead and Storage

Storing Leftovers

Keep any leftover French Onion Stuffed Chicken in an airtight container in the refrigerator for up to 3 days to maintain moisture and flavor.

Freezing

To freeze, wrap each stuffed chicken breast tightly in plastic wrap and then foil before placing in a freezer bag. Freeze for up to 2 months, thawing overnight in the fridge before reheating.

Reheating

Reheat gently in the oven at 325°F (163°C) until warmed through to preserve texture, or microwave covered on medium power to avoid drying out.
