🛒 Ingredients
For the Chicken:
- 4 boneless, skinless chicken breasts
- 1 tablespoon olive oil
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
For the Caramelized Onions:
- 3 large yellow onions, thinly sliced
- 2 tablespoons butter
- 1 tablespoon olive oil
- ½ teaspoon salt
- 1 teaspoon sugar (optional, to enhance caramelization)
- ¼ cup beef broth (or chicken broth)
For Topping:
- 1 cup shredded Gruyère cheese (or Swiss, provolone, or mozzarella)
- ½ cup shredded Parmesan cheese
- Fresh thyme or parsley, for garnish
🔪 Instructions
Step 1: Prepare the Chicken
- Preheat your oven to 400°F (200°C).
- Season chicken breasts with salt, pepper, and garlic powder.
- Heat 1 tablespoon of olive oil in a large oven-safe skillet or cast iron pan.
- Sear chicken for 2–3 minutes per side until golden brown (don’t cook fully yet). Remove from the pan and set aside.
Step 2: Caramelize the Onions
- In the same skillet, add butter and olive oil.
- Add sliced onions and cook over medium-low heat, stirring frequently.
- Sprinkle in salt and sugar to help with browning.
- Continue cooking for 20–25 minutes, until onions are deeply golden and sweet.
- Pour in the beef broth to deglaze the pan, scraping up any flavorful bits. Simmer for 2 minutes until slightly thickened.
Step 3: Assemble and Bake
- Return the seared chicken breasts to the skillet, nestling them into the onions.
- Spoon some onions over each piece of chicken.
- Top generously with Gruyère and Parmesan cheese.
- Transfer the skillet to the oven and bake uncovered for 20–25 minutes, until the cheese is bubbly and the chicken reaches an internal temperature of 165°F (74°C).
Step 4: Serve
- Garnish with fresh thyme or chopped parsley.
- Serve hot with a side of mashed potatoes, roasted green beans, or a crisp salad.
