Ingredients
For the Onions:
- 8 tablespoons butter
- 2 pounds yellow onions, thinly sliced
- 1 teaspoon salt
For the Chicken:
- 1¼ pounds chicken breast cutlets
- 3 tablespoons flour
- 1 teaspoon salt
- ¼ teaspoon black pepper
- 3 tablespoons butter
For the Sauce and Topping:
- ½ cup chicken broth
- ¼ cup red wine
- 1 tablespoon fresh thyme, chopped (plus sprigs for garnish)
- 8 ounces gruyere cheese, shredded
Instructions
- Wilt the Onions: Add 8 tablespoons of butter to a heavy-bottomed pot over low heat. Once melted, add the sliced onions and 1 teaspoon of salt. Stir to combine, cover with a lid, and let the onions wilt gently for 30 minutes.
- Caramelize the Onions: Remove the lid and turn the heat up to medium-low. Toss the onions in the butter and cook uncovered for 45 minutes, stirring occasionally and scraping the pot to prevent sticking. This slow caramelization develops a deep sweet flavor. Once caramelized, remove the onions from the pot and set aside.
- Prepare the Chicken: Preheat the oven to 375°F (190°C). Dust the chicken breasts evenly with flour, 1 teaspoon salt, and black pepper on both sides.
- Sear the Chicken: Turn the heat to medium-high and add 3 tablespoons of butter to the same pot. Once melted, sear the chicken breasts for 3-4 minutes per side until a golden brown crust forms. Remove the chicken from the pot and set aside.
- Make the Sauce: Add the caramelized onions back into the pot along with the red wine and chicken broth. Stir well and let the mixture simmer for 5-6 minutes until it thickens and reduces slightly.
- Bake the Chicken: Nestle each chicken breast into the onion mixture in the pot or an oven-safe dish. Ensure each piece is thoroughly covered with the onions. Top each breast with shredded gruyere and a sprig of fresh thyme. Transfer to the preheated oven and bake for 10 minutes to melt the cheese and finish cooking the chicken.
- Serve: Remove from the oven, let the dish cool slightly, then serve warm and enjoy the savory, rich flavors.
Notes
- Use thinly sliced yellow onions for the best caramelization and sweetness.
- Red wine can be substituted with additional chicken broth if preferred, but it adds depth of flavor.
- Ensure the chicken is seared well to lock in juices before baking.
- This recipe works best in a heavy-bottomed oven-safe skillet or Dutch oven.
- Gruyere cheese is preferred for its melting quality and nutty flavor, but Swiss cheese can be used as a substitute.
