In the last 5 minutes, add thyme leaves and beef broth (if using) to deglaze the pan and intensify the flavor.
Remove from heat and let cool slightly.
In a bowl, mix the caramelized onions with Gruyère and Parmesan cheese.
The key to perfect caramelized onions is low and slow cooking. Don't rush this step – it's what gives the dish its signature French onion flavor!
Stuffing and Cooking the Chicken
Preheat your oven to 375°F (190°C).
Using a sharp knife, carefully cut a pocket into each chicken breast. Don't cut all the way through!
Season the inside and outside of each chicken breast with salt and pepper.
Stuff each pocket with the French onion filling, being careful not to overfill.
Secure the openings with toothpicks if needed.
Heat a tablespoon of oil in an oven-safe skillet over medium-high heat.
Sear the stuffed chicken breasts for 3-4 minutes on each side until golden brown.
Transfer the skillet to the preheated oven and bake for 15-20 minutes, or until the internal temperature reaches 165°F (74°C).
Notes
Remember, the cooking time may vary depending on the size of your chicken breasts. Always use a meat thermometer to ensure they're fully cooked!
