Ingredients
Scale
- 4 boneless, skinless chicken breasts
- Salt and black pepper to taste
- 2 tablespoons olive oil
- 3 large onions, thinly sliced
- 3 cloves garlic, minced
- 1 teaspoon sugar
- 1 teaspoon dried thyme
- 1 cup beef broth
- 1/2 cup white wine
- 1 cup Gruyère cheese, shredded
- Fresh parsley, chopped for garnish
Instructions
- Preheat and Prep: Start by preheating your oven to 375°F (190°C). Season the chicken breasts with salt and pepper.
- Sear Chicken: Heat olive oil in a large oven-proof skillet over medium-high heat. Add the chicken and sear until golden on both sides, about 3-4 minutes per side. Remove and set aside.
- Caramelize Onions: In the same skillet, reduce heat to medium, add onions, garlic, sugar, and thyme. Cook, stirring occasionally, until onions are golden and soft, about 15-20 minutes.
- Deglaze: Pour in the white wine and scrape up any browned bits from the pan. Add beef broth and bring to a simmer.
- Combine and Bake: Return the chicken to the skillet, nestling it into the onions. Top with shredded Gruyère cheese. Bake in the preheated oven for 20-25 minutes, until the chicken is cooked through and the cheese is bubbly and golden.
- Garnish and Serve: Sprinkle chopped parsley over the top before serving.
