• 4 boneless, skinless chicken breasts
  • 1 tsp salt
  • ½ tsp black pepper
  • 1 tsp garlic powder
  • 2 tbsp olive oil (or butter)

For the Mushroom Filling:

  • 8 oz cremini or baby bella mushrooms, finely chopped
  • 2 cloves garlic, minced
  • 2 tbsp unsalted butter
  • ¼ cup grated Parmesan cheese
  • ½ cup shredded mozzarella or cheddar cheese
  • ¼ tsp dried thyme
  • Salt and pepper to taste

For the Garlic Butter Sauce:

  • 4 tbsp unsalted butter
  • 4 cloves garlic, minced
  • 2 tbsp heavy cream or half-and-half (optional, for richness)
  • Fresh parsley, chopped (for garnish)

🔪 Step-by-Step Instructions

Step 1: Prep the Chicken

Butterfly each chicken breast by slicing horizontally through the center (don’t cut all the way through). Open them up like a book and season the inside with salt, pepper, and garlic powder.

Step 2: Make the Filling

In a skillet over medium heat, melt the butter. Add garlic and mushrooms and sauté for 5–6 minutes until softened and golden. Stir in Parmesan, mozzarella, thyme, salt, and pepper. Remove from heat.

Step 3: Stuff the Chicken

Divide the mushroom mixture evenly among the chicken breasts, mounding it in the center. Fold the chicken closed and secure with toothpicks or skewers if needed.

Step 4: Sear the Chicken

Heat olive oil or butter in a large oven-safe skillet over medium-high heat. Sear the chicken for 3–4 minutes per side until golden brown.

Step 5: Bake Until Tender

Transfer the skillet to a preheated oven at 375°F (190°C) and bake for 15–20 minutes , or until the chicken is fully cooked and juices run clear.

Step 6: Make the Garlic Butter Sauce

While the chicken bakes, melt butter in a small saucepan. Add minced garlic and cook for 1–2 minutes until fragrant. Add cream (if using) and simmer slightly.

Step 7: Serve & Enjoy

Top each chicken breast with garlic butter sauce and fresh parsley. Serve hot with mashed potatoes, rice, or roasted vegetables.
