Ingredients You’ll Need
What I love most about Cheesy Garlic Butter Mushroom Stuffed Chicken is that it relies on simple, fresh staples—each playing a starring role in taste and texture. Whether you’re impressing guests or just treating yourself to something wonderful, these key ingredients make every bite utterly delicious.
- Chicken breasts: Choose boneless, skinless breasts for easy stuffing and perfect juiciness; medium-to-large works best so you’ll have enough room for that delicious filling.
- Olive oil: Adds richness to both the mushroom sauté and chicken, and keeps everything from sticking in the pan.
- Unsalted butter: Gives the mushrooms incredible flavor and a silky texture as they cook down.
- Mushrooms: Baby bellas or cremini are especially tasty, bringing earthy depth and moisture to the filling.
- Garlic: A generous amount infuses every component with aromatic, irresistible flavor.
- Fresh thyme: Adds a fragrant, herby brightness that wakes up the mushrooms (dried works too if that’s what you have).
- Mozzarella cheese: Shreds melt beautifully, ensuring every forkful is gooey and satisfying.
- Parmesan cheese: Brings salty, nutty complexity and helps brown the crust of the stuffing.
- Salt and black pepper: The basic seasonings to enhance everything without overpowering the other flavors.
- Toothpicks: Essential for securing your stuffed chicken and keeping all that goodness inside while it cooks.
How to Make Cheesy Garlic Butter Mushroom Stuffed Chicken
Step 1: Prep the Chicken Breasts
Let’s start with the foundation: carefully cut a deep pocket into the side of each chicken breast, making sure not to slice all the way through. This gives you a beautiful little envelope to stuff full of deliciousness. Season each breast generously with salt and black pepper—this is your chance to pack in flavor from the very start!
Step 2: Sauté the Mushrooms and Garlic
Heat olive oil and unsalted butter in a skillet over medium heat until the butter is melted and foamy. Toss in your sliced mushrooms and cook, stirring occasionally, until golden and softened (about 5–6 minutes). Sprinkle in the minced garlic and fresh thyme, letting everything cook for 30 seconds longer to release those beautiful aromas. Set aside to cool slightly (no one wants to melt the cheese too soon!).
Step 3: Stuff the Chicken
Spoon a generous portion of your mushroom mixture into each chicken pocket, then pile in the mozzarella and Parmesan. Don’t hesitate to really stuff them—you want an explosion of cheese and mushrooms in every bite! Use toothpicks to secure the openings so the filling stays put during cooking.
Step 4: Sear to Lock in Flavor
Set your skillet back over medium heat. Arrange the stuffed chicken breasts seam side up, and sear each side for 3–4 minutes until they develop a lovely golden-brown crust. This step adds rich flavor and keeps the chicken ultra-juicy inside.
Step 5: Bake to Finish
Transfer the entire skillet to a 375°F oven, or use a baking dish if your skillet isn’t oven-safe. Bake for 15–20 minutes, or until the chicken reaches an internal temperature of 165°F. The cheese should be bubbling, and the kitchen smells simply irresistible. Remove the toothpicks before serving, and get ready to dig in!
How to Serve Cheesy Garlic Butter Mushroom Stuffed Chicken

Garnishes
For a fresh pop of color and added flavor, I love topping each chicken breast with a sprinkle of chopped parsley or thyme leaves just before serving. A touch of grated Parmesan over the top is never a bad idea either!
Side Dishes
This dish pairs beautifully with everything from buttery mashed potatoes and fluffy rice to simply roasted veggies or a crisp green salad. The rich, savory flavors of Cheesy Garlic Butter Mushroom Stuffed Chicken are especially comforting with sides that soak up some of that irresistible sauce.
Creative Ways to Present
If you want to make things restaurant-fancy, slice each stuffed chicken breast on a diagonal and fan out the slices on a platter. Drizzle any extra pan juices over the top, then scatter fresh herbs for a showstopping main course that will impress any guest!
Make Ahead and Storage
Storing Leftovers
Place any leftover Cheesy Garlic Butter Mushroom Stuffed Chicken in an airtight container and refrigerate for up to 3 days. The flavors deepen as they sit, making for a delicious lunch or quick dinner the next day.
Freezing
You can freeze these stuffed chicken breasts either before or after baking. Let them cool completely, then wrap tightly with foil and place in a freezer bag. They’ll keep well for up to 2 months—just remember to label and date them for easy meals down the road.
Reheating
To reheat, thaw overnight in the fridge if frozen, then bake in a 325°F oven (covered with foil) until heated through. The cheese will melt again, and the chicken will stay juicy. A quick zap in the microwave works too for a fast lunch!
FAQs
Can I use a different cheese instead of mozzarella?
Absolutely! Cheesy Garlic Butter Mushroom Stuffed Chicken tastes fantastic with provolone, fontina, or even sharp white cheddar—just use a melty cheese for that signature gooey texture.
What type Main Course
Baby bella or cremini mushrooms are my favorites for their rich, earthy flavor, but white button or even wild mushrooms also work beautifully in this dish.
How do I keep the filling from falling out?
Make sure to cut a deep enough pocket without slicing all the way through, then stuff gently and secure well with toothpicks. Searing seam side up first helps seal everything in, too!
Can I make Cheesy Garlic Butter Mushroom Stuffed Chicken ahead of time?
Yes! You can assemble the stuffed, uncooked chicken up to a day in advance and keep it in the fridge. When ready to cook, sear and bake as directed for a fresh and easy meal.

Yes, Cheesy Garlic Butter Mushroom Stuffed Chicken is naturally gluten-free as written, so it’s perfect for anyone avoiding gluten or aiming for a low-carb dinner.
