2tablespoonsButterRoom temperature or melted for sautéing
8ouncesMushroomsSliced (about 2 cups)
4clovesGarlicMinced
1/2cupShredded mozzarella cheesePacked
1/4cupGrated Parmesan cheeseFreshly grated if possible
2tablespoonsChopped fresh parsleyFor garnish
Instructions
Preheat the oven to 400°F (200°C). Lightly grease a baking dish or line with foil for easy cleanup.
Using a sharp knife, cut a pocket into each chicken breast: place the breast flat and slice horizontally into the thick side, stopping about 1/2 inch from the edge.
Season both the inside and outside of each chicken breast generously with salt and pepper.
In a large skillet, heat 1 tablespoon olive oil over medium-high heat until shimmering.
Add 2 tablespoons butter to the skillet and let it melt, swirling to coat the pan.
Add the sliced mushrooms and cook, stirring occasionally, until they are golden brown and tender, about 5 to 7 minutes.
Add the minced garlic to the skillet and cook for an additional 1 to 2 minutes, stirring constantly.
Remove the skillet from heat and let the mushroom-garlic mixture cool slightly.
In a small bowl, mix together the shredded mozzarella and grated Parmesan until evenly combined.
Stuff each chicken breast pocket with a spoonful of the mushroom mixture and then the cheese mixture, pressing gently.
Place the stuffed chicken breasts seam-side down in the prepared baking dish. Bake for 25 to 30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
Remove from oven, let rest for 5 minutes, then garnish with chopped fresh parsley before serving.
Notes
For a lighter version, swap half the mozzarella for part-skim cheese or use less butter in the sauté.
