This mouthwatering Cheesy Garlic Butter Mushroom Stuffed Chicken transforms ordinary chicken breasts into an extraordinary dinner that looks and tastes like restaurant quality. The combination of savory mushrooms, creamy cheese, and aromatic garlic creates a flavor explosion in every bite while keeping the chicken incredibly moist and tender.
I first created this recipe when trying to elevate our usual chicken dinner routine. My husband now requests it whenever we have company over because it never fails to impress even the pickiest eaters in our circle.

How To Make Cheesy Garlic Butter Mushroom Stuffed Chicken
- Prep the chicken:
- Create deep pockets in each chicken breast by cutting horizontally with a sharp knife being careful not to slice all the way through. This creates the perfect pocket for maximum filling while keeping everything contained during cooking.
- Make the filling:
- Combine the chopped mushrooms cream cheese mozzarella minced garlic and dried herbs in a bowl. The softened cream cheese works as the perfect binding agent while the mushrooms provide earthy flavor that pairs perfectly with the garlic and herbs.
- Stuff the chicken:
- Fill each pocket generously with the mushroom mixture pushing it deep into the pocket. For best results try to distribute the filling evenly throughout the entire pocket rather than just in the center.
- Sear to perfection:
- Heat butter in a skillet until bubbling then carefully place each stuffed breast into the hot pan. Allow each side to develop a deep golden crust which seals in juices and adds tremendous flavor through caramelization.
- Bake to completion:
- Transfer the seared chicken to a baking sheet sprinkle with parmesan and bake until the internal temperature reaches 165°F. This two step cooking process ensures a beautiful exterior and perfectly cooked interior without drying out the chicken.
The mushroom filling is truly the star of this dish. I discovered that finely chopping the mushrooms rather than slicing them creates a better texture and allows them to release more flavor into the cream cheese base. My family initially claimed they disliked mushrooms until I served this dish which converted even the strongest mushroom skeptics.
Make Ahead Options
This stuffed chicken recipe is perfect for meal planning. You can prepare the stuffed chicken breasts up to 24 hours ahead of time and keep them covered in the refrigerator. Simply take them out about 15 minutes before cooking to take the chill off for more even cooking. The mushroom mixture can also be made up to 2 days in advance and stored separately which makes assembly quick and easy when ready to cook.
Serving Suggestions
While this Cheesy Garlic Butter Mushroom Stuffed Chicken is certainly hearty enough to be the star of your meal it pairs beautifully with simple sides that complement without competing. A fresh green salad with a light vinaigrette balances the richness perfectly. For a more substantial meal roasted asparagus or broccoli works wonderfully as does a side of garlic mashed potatoes to soak up any extra sauce from the chicken. For a lower carb option consider serving with cauliflower rice or mashed cauliflower.

Troubleshooting Tips
Sometimes stuffed chicken can present challenges to even experienced cooks. If your filling keeps escaping during cooking try securing the openings with toothpicks before searing. Remove them before serving of course. For chicken breasts that vary greatly in thickness consider pounding them to an even thickness before cutting the pocket which helps them cook more evenly. If your chicken looks done on the outside but you are unsure about the inside use an instant read thermometer to check for the safe internal temperature of 165°F without cutting into the chicken and losing precious juices.

- → How do I know when the chicken is fully cooked?
