Ingredients You’ll Need
The beauty of Cheesy Garlic Butter Mushroom Stuffed Chicken is in its carefully chosen, everyday ingredients. Each one brings something special, whether that’s creaminess, bite, or irresistible aroma—so don’t skip a thing!
- Boneless skinless chicken breasts (4): The perfect blank canvas, they cradle the delicious filling and stay moist through baking.
- Salt (1 teaspoon): Essential for bringing out the flavors in both the chicken and the filling.
- Black pepper (1/2 teaspoon): Adds a gentle heat and depth to every bite.
- Olive oil (2 tablespoons): For that gorgeous sear and subtle Mediterranean fragrance.
- Unsalted butter (2 tablespoons): Makes the mushroom filling rich and buttery without overwhelming the dish.
- Garlic, minced (3 cloves): The key to a deeply aromatic, appetizing stuffing.
- Mushrooms, sliced (8 oz): Earthy and juicy, they soak up the garlic butter beautifully.
- Fresh thyme leaves (1 teaspoon) or dried thyme (1/2 teaspoon): Brings a lovely herbal brightness to the filling.
- Shredded mozzarella cheese (1/2 cup): Melts into stretchy, gooey ribbons for that authentic cheesy experience.
- Grated Parmesan cheese (1/4 cup): Adds nutty, salty complexity and helps bind the filling together.
- Fresh parsley, chopped (1 tablespoon, optional): A dash of green freshness to finish everything off beautifully.
How to Make Cheesy Garlic Butter Mushroom Stuffed Chicken
Step 1: Prep the Chicken Breasts
Start by carefully slicing a pocket into the side of each chicken breast. Take your time with this step: use a sharp knife and make sure not to cut all the way through. Season the inside and outside of the chicken generously with salt and pepper to make sure every bite is flavorful.
Step 2: Sauté the Mushrooms and Garlic
Heat olive oil and butter in a large, oven-safe skillet over medium heat. When the butter is melted and just starting to froth, toss in your minced garlic and sliced mushrooms. Sauté for about 5–6 minutes, stirring occasionally, until the mushrooms are gloriously golden and softened and that garlicky aroma fills the kitchen. Sprinkle in the thyme and give everything one last toss, then take the pan off the heat to cool slightly.
Step 3: Mix the Cheesy Mushroom Filling
Once the mushroom mixture is just cool enough to handle, stir in the mozzarella and Parmesan cheeses. Don’t hold back—a generous hand with the cheese is what makes Cheesy Garlic Butter Mushroom Stuffed Chicken truly magical. The heat from the mushrooms will begin to melt the cheeses, letting everything meld together.
Step 4: Stuff the Chicken
Spoon the mushroom-cheese mixture into each chicken pocket, filling them as much as you can without overflowing. If your chicken breasts are on the smaller side, just squeeze in as much filling as fits securely. Use toothpicks to hold everything in place—think of them as your secret tool to keep all that cheesy goodness where it belongs.
Step 5: Sear for Flavor
Wipe out any excess bits from your skillet, add a little more olive oil if needed, and crank up the heat. Sear the stuffed chicken breasts for 3–4 minutes on each side, just until they pick up a lovely golden crust. This quick step builds unbelievable flavor before baking finishes the job.
Step 6: Bake to Perfection
Pop the whole skillet (or transfer the chicken to a baking dish if your handle isn’t oven-safe) into the preheated oven. Bake for 15–20 minutes, or until the chicken reaches 165°F (74°C) at its thickest point. Let it rest briefly, then gently remove any toothpicks before serving.
How to Serve Cheesy Garlic Butter Mushroom Stuffed Chicken

Garnishes
Finish your Cheesy Garlic Butter Mushroom Stuffed Chicken with a generous sprinkle of freshly chopped parsley or even a little extra Parmesan. A squeeze of lemon over the top just before serving adds a bright, zippy contrast to the rich filling—and looks gorgeous on the plate.
Side Dishes
This dish loves classic sides. Creamy mashed potatoes, simple buttered pasta, or a crisp green salad are all wonderful partners. Roasted vegetables or garlicky green beans also soak up those cheesy, buttery pan juices perfectly.
Creative Ways to Present
Slice the chicken breasts crosswise before plating for a beautiful spiral effect that shows off the cheesy mushroom filling. Arrange on individual plates with a drizzle of pan juices—or serve family-style on a rustic platter surrounded by roasted potatoes for an impressive centerpiece.
Make Ahead and Storage
Storing Leftovers
Leftover Cheesy Garlic Butter Mushroom Stuffed Chicken stores beautifully. Let the chicken cool completely, then wrap tightly or transfer to an airtight container. Refrigerate for up to 3 days—the flavors get even cozier overnight!
Freezing
You can freeze the cooked stuffed chicken for up to 2 months. Wrap each piece individually in foil and place them in a freezer-safe bag. Thaw overnight in the fridge before reheating; the texture remains amazingly tender.
Reheating
For best results, reheat the chicken gently in a 325°F oven, loosely covered, until warmed through (about 15 minutes). If you’re in a hurry, a quick zap in the microwave works too—just cover with a damp paper towel to keep it moist.
FAQs
Can I use chicken thighs instead of breasts?
Absolutely! Boneless, skinless chicken thighs work well, though you’ll need to adjust the stuffing amount and cooking time—thighs are smaller and sometimes cook a little faster.
What other cheeses work in the stuffing?
Feel free to experiment! Gruyère, Fontina, Swiss, or even sharp cheddar all melt beautifully and pair deliciously with mushrooms and garlic.
How do I prevent the filling from leaking out?
Be sure to slice a deep but not too wide pocket into your chicken and secure the edges tightly with toothpicks. Don’t over-stuff and you’ll keep those cheesy treasures hidden inside.
Is this recipe gluten-free?
Yes, Cheesy Garlic Butter Mushroom Stuffed Chicken is naturally gluten-free. Just check your cheeses and any seasonings to ensure they’re free from additives or cross-contamination.
Can I prepare it ahead of time?
Definitely! You can stuff and assemble the chicken up to a day in advance and keep it covered in the fridge. Add a couple of extra minutes to the baking time when cooking straight from the fridge.
