Ingredients

For the Mushrooms:

  • 8 tbsp butter
  • 8 oz brown mushrooms, sliced
  • 4 cloves garlic, minced
  • 2 tbsp fresh parsley, chopped
  • Salt and pepper, to taste

For the Chicken:

  • 4 skinless, boneless chicken breasts
  • Salt and pepper, to taste
  • 1 tsp onion powder
  • 1 tsp dried parsley
  • 8 slices mozzarella cheese
  • ¼ cup fresh Parmesan cheese, grated

For the Creamy Garlic Parmesan Sauce (Optional):

  • 1 tbsp olive oil
  • 2 large garlic cloves, minced
  • 1 tbsp Dijon mustard
  • cup alf-and-half (or substitute with ¾ cup whole milk + ¾ cup reduced-fat cream)
  • ½ cup Parmesan cheese, finely grated
  • Salt and pepper, to taste
  • ½ tsp cornstarch mixed with 2 tsp water (optional, for thickening)
  • 2 tbsp fresh parsley, chopped

Instructions 

1. Prepare the Mushrooms:

  • Preheat the oven to 400°F (200°C).
  • Heat butter in a large oven-safe skillet over medium heat.
  • Add garlic and sauté for about 1 minute until fragrant.
  • Stir in mushrooms, salt, pepper, and parsley. Cook until mushrooms soften.
  • Set aside to cool while you prepare the chicken.

Prepare the Chicken:

  • Pat chicken breasts dry with a paper towel.
  • Season with salt, pepper, onion powder, and dried parsley, rubbing to coat evenly.
  • Slice a pocket into the thickest part of each chicken breast.
  • Stuff each pocket with 2 slices of mozzarella and a portion of the mushroom mixture.
  • Sprinkle 1 tbsp Parmesan cheese on top of the mushrooms in each breast.
  • Secure the opening with 2–3 toothpicks to keep the filling in place.

3. Cook the Chicken:

  • In the same skillet with leftover garlic butter, heat over medium-high heat.
  • Sear the stuffed chicken on both sides until golden brown.
  • Cover the skillet and transfer it to the preheated oven.
  • Bake for 20 minutes or until the chicken is cooked through (internal temp: 165°F/75°C).
  • Remove from the oven and let rest while you prepare the sauce (if making).

4. Make the Cream Sauce (Optional):

  • In the same skillet, heat olive oil over low heat.
  • Add garlic and sauté for 1 minute until fragrant.
  • Stir in Dijon mustard and half-and-half (or cream substitute).
  • Bring to a gentle simmer, then add any remaining mushrooms and Parmesan cheese.
  • Let the sauce cook until the Parmesan melts slightly.
  • (Optional) For a thicker sauce, add the cornstarch mixture and stir quickly to combine.
  • Season with salt and pepper, then stir in fresh parsley.
  • Return the chicken to the pan and coat with the sauce before serving.

5. Serve & Enjoy:

  • Half-and-half substitute: If you don’t have half-and-half, use ¾ cup whole milk + ¾ cup reduced-fat cream.
  • Make it low-carb: Serve with zucchini noodles, cauliflower rice, or a simple green salad.
