Garlic Butter Mushroom Chicken fills four butterflied breasts with browned mushrooms and mozzarella, sears them until golden, then finishes them in the oven. A warm garlic-butter drizzle with parsley and optional lemon gives the stuffed chicken a bright, savory finish.
The recipe serves 4 and takes about 40 minutes, split between 20 minutes of preparation and 20 minutes of cooking. Careful butterflying, cooled filling, secure toothpicks, and a 165°F center keep the cheese inside and the chicken juicy.
Garlic Butter Mushroom Chicken Ingredients
For the filling, use 1 tablespoon butter, 1 tablespoon olive oil, 1½ cups finely chopped button or cremini mushrooms, 2 minced garlic cloves, ½ teaspoon dried thyme, ¼ teaspoon salt, and ¼ teaspoon black pepper.
For the chicken, use 4 boneless skinless breasts, 1 teaspoon salt, ½ teaspoon pepper, 1 teaspoon paprika, 1 teaspoon garlic powder, 1 tablespoon olive oil, 4 mozzarella slices, and toothpicks or twine. For the sauce, use 2 tablespoons butter, 2 minced garlic cloves, 1 tablespoon chopped parsley, and optional juice of ½ lemon.

How to Make Garlic Butter Mushroom Chicken
- Heat 1 tablespoon butter and 1 tablespoon oil over medium heat. Cook mushrooms 5 to 6 minutes until browned and soft.

- Heat the oven to 375°F. Butterfly all 4 breasts without cutting through. Season with 1 teaspoon salt, ½ teaspoon pepper, paprika, and garlic powder.
- Divide mushroom filling among the breasts, add one mozzarella slice to each, fold closed, and secure.
- Heat 1 tablespoon oil in an oven-safe skillet. Sear chicken 3 to 4 minutes per side.
- Bake 15 to 20 minutes, until 165°F inside.
- Melt 2 tablespoons butter, cook the other 2 garlic cloves 1 to 2 minutes, then add parsley and optional lemon juice. Remove fasteners, rest chicken 5 minutes, and drizzle with sauce.

Brown the Mushroom Filling
Finely chop the full cup and a half of mushrooms. Small pieces fit neatly inside a breast and are less likely to push open the seam. Heat one tablespoon each butter and olive oil, then cook the mushrooms for 5 to 6 minutes.
Let their moisture evaporate and their edges brown. Add the first two minced garlic cloves, thyme, quarter teaspoon salt, and quarter teaspoon pepper. Cook only 1 to 2 minutes more, then move the filling off heat so it can cool slightly.

Butterfly Without Cutting Through
Place one hand flat over a breast and guide a sharp knife horizontally through the side, stopping before the opposite edge. Open it like a book. Repeat with all four breasts, creating a broad pocket rather than two separate cutlets.
Season inside and outside with the chicken's measured salt, pepper, paprika, and garlic powder. Keeping the hinge intact helps contain the filling and gives toothpicks or twine a secure edge to close.
Stuff Four Equal Portions
Divide the cooled mushrooms into four portions. Spoon one portion into each opened breast and place exactly one mozzarella slice over it. Fold the chicken closed without forcing filling toward the edge.
Secure each seam with toothpicks or kitchen twine. Count the toothpicks used so all can be removed later. If the filling is still hot, it can soften the cheese prematurely and make the closed breast difficult to handle.
Sear Before Baking
Heat the remaining tablespoon olive oil in an oven-safe skillet over medium-high heat. Place the four breasts in carefully and sear 3 to 4 minutes per side, until the outside is golden.
Searing builds color and flavor, but it does not finish the thick stuffed centers. Turn with tongs rather than piercing the chicken, and keep the fastened seams supported. Use the same skillet in the oven to preserve the flavorful browned surface.
Bake to a Safe Center
Transfer the skillet to the 375°F oven and bake for 15 to 20 minutes. Insert a thermometer into the thickest chicken area, avoiding the mozzarella pocket and metal pan. The chicken is ready at 165°F.
Stuffed breasts vary in thickness, so temperature is more reliable than exterior color. Remove individual pieces as they reach the target if necessary rather than extending every portion until the largest is far overcooked.
Prepare the Garlic Butter
While the chicken bakes, melt two tablespoons butter in a small saucepan. Add the remaining two minced garlic cloves and cook for 1 to 2 minutes until fragrant, not brown. Stir in the tablespoon chopped parsley.
The juice of half a lemon is optional. Add it off heat for brightness if desired. Keep the sauce warm without boiling, since high heat can darken the garlic and dull the fresh parsley.
Rest and Remove Every Fastener
Rest the baked breasts for 5 minutes before slicing. This pause lets juices settle and gives the melted cheese a moment to become less fluid. Remove every toothpick or piece of twine before the chicken reaches a plate.
Drizzle the garlic butter over the top just before serving. Slice at a slight angle if you want to show the mushroom and mozzarella center, using a sharp knife so the filling remains inside each portion.
Serving and Storage
Serve one stuffed breast per person with a simple green vegetable, roasted potatoes, or rice. The mushroom filling and butter sauce are rich, so straightforward sides keep the plate balanced and leave the chicken as the focus.
Refrigerate cooled leftovers in a covered container for up to three days. Reheat gently in a covered 325°F oven until hot. Remove all fasteners before storage and avoid repeated reheating, which can dry the chicken and make mozzarella rubbery.
Prevent Leaks and Dry Chicken
Leaks usually result from overfilling, hot mushroom mixture, an incomplete chicken hinge, or loose fasteners. Dry chicken comes from relying on time after the center has already reached 165°F.
Cool the filling, divide it evenly, secure each seam, and use a thermometer. These practical controls preserve the exact ingredient quantities while producing four golden breasts with moist centers and a visible mushroom-cheese filling.
Conclusion
Brown chopped mushrooms with butter, oil, garlic, and seasonings. Butterfly and season four breasts, fill each with mushrooms and one mozzarella slice, secure, and sear 3 to 4 minutes per side. Bake at 375°F for 15 to 20 minutes to 165°F, rest 5 minutes, remove fasteners, and add garlic butter.
