Ingredients
  

For the Chicken
  • 4 pieces boneless, skinless chicken breasts Juicy and tender, these will cradle the delicious filling.
  • ½ cup beef or chicken broth To infuse the dish with rich flavors.
  • 1 cup shredded Gruyère cheese Nutty and creamy cheese that is the star of the filling.
  • ½ cup sour cream Adds creaminess and tang.
  • 1 tablespoon Dijon mustard For a subtle kick.
  • 1 tablespoon chopped parsley For garnish.
For the Onion Filling
  • 2 large onions, thinly sliced They will caramelize to create a sweet flavor profile.
  • 2 tablespoons butter Adds richness and depth to the onions.
  • 1 tablespoon olive oil To help sauté the onions and keep things healthy.
  • 3 cloves garlic, minced Introduces a lovely aromatic element.
  • 1 teaspoon dried thyme For a hint of earthiness.
  • 1 teaspoon salt To enhance all the flavors.
  • ½ teaspoon black pepper For a pinch of heat.

Method
 

Preparation
  1. Preheat the oven to 375°F (190°C).
  2. In a large skillet, melt butter and olive oil over medium heat. Add sliced onions and cook for 15-20 minutes, stirring frequently until they are golden brown.
  3. Stir in minced garlic and dried thyme. Cook for an additional minute until fragrant, then remove from heat.
  4. In a mixing bowl, combine the caramelized onions, shredded Gruyère cheese, sour cream, and Dijon mustard. Mix until well blended.
  5. With a sharp knife, carefully slice each chicken breast horizontally to create a pocket, being careful not to cut all the way through.
  6. Generously fill each chicken breast with the onion and cheese mixture, ensuring it’s packed but not overflowing.
  7. Season the outside of the chicken breasts with salt and pepper.
Cooking
  1. In the same skillet, add a little more oil if needed, and brown each chicken breast for about 3-4 minutes on each side.
  2. Pour broth into the skillet, then place the browned chicken breasts in the oven for 20-25 minutes, or until the chicken is cooked through.
  3. Once cooked, remove from the oven and let it rest for a few minutes. Garnish with fresh parsley before slicing open and serving.

Notes

Low and slow is key to achieving beautifully caramelized onions. Experiment with different cheeses and be careful not to overstuff the chicken. Searing the chicken on a hot skillet creates a nice golden crust.
