Ingredients
Scale
Main Protein:
- 4 boneless, skinless chicken breasts
Vegetables and Aromatics:
- 3 large yellow onions
- 2 teaspoons fresh thyme leaves
Flavor Enhancers and Cheese:
- ½ cup beef broth
- 1 tablespoon balsamic vinegar
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 cup shredded Gruyere cheese
- ¼ cup grated Parmesan cheese
- 2 tablespoons olive oil
- 1 tablespoon butter
- Fresh parsley (optional)
Instructions
- Warm your oven to exactly 375°F and lightly coat a 9×13 inch baking dish with cooking spray.
- Pour 2 tbsp olive oil and 1 tbsp butter into a large skillet. Sauté 3 thinly sliced yellow onions over medium heat for 18-20 minutes until deep golden and caramelized.
- Stir 2 tsp fresh thyme leaves, 1 tbsp balsamic vinegar, ½ tsp salt, and ¼ tsp black pepper into your caramelized onions. Remove from heat.
- Season 4 chicken breasts with additional salt and pepper. Quickly sear them in the same skillet for 2-3 minutes on each side until light golden.
- Nestle seared chicken breasts into your prepared baking dish. Spread caramelized onions evenly across the top of each breast.
- Pour ½ cup beef broth around the chicken pieces, ensuring liquid surrounds but doesn’t completely cover the meat.
- Sprinkle 1 cup shredded Gruyere cheese and ¼ cup Parmesan cheese generously over each chicken breast.
- Cover the baking dish tightly with aluminum foil. Bake at 375°F for exactly 20 minutes.
- Remove foil and continue baking for 12-15 minutes until cheese turns golden and chicken reaches 165°F internal temperature.
- Allow the dish to rest for 5 minutes. Optionally garnish with chopped fresh parsley before serving.
Notes
- Caramelizing onions takes patience, so don’t rush the process and let them slowly develop that deep golden color for maximum flavor.
- If Gruyere cheese is too expensive, swap it with Swiss or provolone for a similar rich and melty texture.
- Salt the chicken before searing to help develop a beautiful golden crust and lock in moisture during baking.
- For a lower-carb version, serve the chicken over cauliflower rice or alongside roasted vegetables instead of traditional sides.
