How to Make French Onion Stuffed Chicken
-
Preheat the oven to 400°F (200°C). Lightly grease a 9×12-inch baking dish and set it aside to ensure your chicken doesn’t stick while it bakes.
-
Melt the butter in a large skillet over medium-high heat. Add the onions, seasoning them with salt, pepper, and half of the fresh chopped thyme. Cook for 5-8 minutes until they become soft and translucent.
-
Reduce the heat to medium and continue cooking, stirring occasionally. Let the onions caramelize until they turn a deep golden brown, which should take about 15 minutes. If the pan gets too dry, pour in 1/4 cup of broth to keep them moist.
-
Deglaze the pan (optional) with white wine, sherry, or balsamic vinegar, scraping up any tasty bits stuck to the bottom. Allow it to cook for a minute until the sauce thickens slightly, adding another layer of flavor to the onions.
-
Stir in the minced garlic and cook for about 1 minute until fragrant. Then, turn off the heat and let the mixture cool slightly to prepare for stuffing.
-
Cut the chicken breasts in half horizontally to create pockets. Season the chicken inside and out with salt, pepper, garlic powder, and ground thyme, ensuring every bite is full of flavor.
-
Spoon 1-2 tablespoons of caramelized onions into each pocket. Then, stuff each chicken breast with both cheeses and seal the pockets with toothpicks to keep the filling inside while cooking.
-
Transfer the remaining caramelized onions from the skillet to the prepared baking dish, mixing in the remaining 1/4 cup of broth to create a sumptuous bed for the chicken. Set aside.
-
Heat the oil in the same skillet over medium-high heat. Sear the stuffed chicken breasts for about 4 minutes on each side until they develop a lovely golden crust (they won’t be fully cooked yet).
-
Arrange the browned chicken on top of the caramelized onions in the baking dish. Drizzle some of the sauce over each breast and top with the rest of the chopped thyme. Bake for 15-20 minutes or until the chicken is fully cooked and the cheeses are melty and bubbly.
-
Discard the toothpicks. Serve the chicken hot, accompanied by the delicious pan juices and onions to elevate each bite.
Optional: Garnish with fresh thyme leaves for a beautiful presentation.
