Creating Gouda & Mushroom Stuffed Chicken is simple if you follow these straightforward steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C) and prepare a baking dish by lightly greasing it with cooking spray or a drizzle of olive oil.
2. Sauté Mushrooms: In a skillet over medium heat, add the olive oil. Once hot, add the diced mushrooms and garlic. Sauté for about 5-7 minutes until the mushrooms are tender and golden.
3. Mix Filling: In a bowl, combine the sautéed mushrooms, shredded Gouda cheese, onion powder, salt, and black pepper. Stir until well mixed.
4. Prep Chicken Breasts: Carefully cut a pocket into each chicken breast by slicing horizontally, ensuring you don’t cut all the way through.
5. Stuff Chicken: Spoon the Gouda and mushroom mixture into each chicken breast pocket. Use toothpicks or kitchen twine to secure the openings if necessary.
6. Bake Chicken: Place the stuffed chicken breasts in the prepared baking dish. Bake in the preheated oven for 30-35 minutes or until the chicken is cooked through and the internal temperature reaches 165°F (75°C).
7. Rest Chicken: Once done, remove the chicken from the oven and let it rest for 5 minutes before serving. This helps retain the juices and flavors.
8. Garnish and Serve: If desired, sprinkle with fresh parsley for a pop of color before slicing and serving.

By following these steps, you’ll create a delicious and impressive meal that is sure to please everyone at the table.
