Instructions

  1. Step 1: Preheat oven to 375°F. Using a sharp knife, carefully cut a pocket into each of the 2 boneless skinless chicken breasts. Stuff each pocket with 1/4 cup shredded mozzarella cheese and 3 chopped fresh basil leaves. Secure with toothpicks if needed.
  2. Step 2: Heat 1 tbsp olive oil and 1 tbsp unsalted butter in an oven-safe skillet over medium-high heat until hot. Season stuffed chicken breasts with 1/2 tsp salt and 1/4 tsp black pepper, then sear for 3-4 minutes per side until golden brown.
  3. Step 3: Transfer the skillet to the oven and bake the chicken breasts for 15-18 minutes until cooked through and internal temperature reaches 165°F.
  4. Step 4: While chicken bakes, melt 2 tbsp unsalted butter in a separate pan over medium heat. Add 8 oz sliced cremini mushrooms and 1 minced garlic clove, sautéing for 5-6 minutes until mushrooms are browned and tender.
  5. Step 5: Pour 1/2 cup heavy cream into the mushroom mixture, stir, and simmer for 3-4 minutes until the sauce thickens and coats the back of a spoon. Season with 1/2 tsp salt and 1/4 tsp black pepper.
  6. Step 6: Remove toothpicks from chicken, plate, and spoon creamy mushroom sauce over the top before serving.
