Ingredients Notes

The beauty of this dish lies in its simplicity. Each ingredient plays a key role in delivering maximum flavor and perfect texture.

Chicken Breasts: Use boneless, skinless chicken breasts that are thick enough to create a pocket for the stuffing. You’ll want them to hold up well during cooking without splitting open.
Mushrooms: Baby bella mushrooms are my go-to for their rich, earthy flavor. Dice them finely so they cook evenly and blend seamlessly with the cheese.
Cheese: Mozzarella provides a creamy, gooey melt, while Parmesan adds a sharp, nutty contrast. You can experiment with other cheeses, but this combination is foolproof.
Garlic: Fresh garlic is essential for both the stuffing and the butter sauce. Its robust flavor complements the mushrooms and enhances the buttery richness.
Butter: A high-quality unsalted butter makes all the difference, creating a luscious sauce that coats the chicken beautifully.

Optional equipment: A sharp knife for creating a pocket in the chicken and toothpicks to secure the filling during cooking.

How To Make This Cheesy Garlic Butter Mushroom Stuffed Chicken

Creating this Cheesy Garlic Butter Mushroom Stuffed Chicken is easier than you might think. Follow these steps for a foolproof result:

Prepare the Chicken
Start by carefully slicing each chicken breast to create a pocket. Be sure not to cut all the way through. Season the chicken inside and out with salt and pepper to enhance the flavors.
Make the Filling
In a skillet, sauté diced mushrooms in a little olive oil over medium heat until tender. Add minced garlic and cook until fragrant, about 1 minute. Remove from heat and mix the mushrooms with shredded mozzarella and Parmesan cheese.
Stuff the Chicken
Spoon the mushroom and cheese mixture into each chicken breast, filling them generously. Secure the edges with toothpicks to keep the filling from spilling out during cooking.
Sear the Chicken
Heat a large skillet with a splash of olive oil over medium-high heat. Sear the stuffed chicken breasts for 2-3 minutes per side until golden brown. This step locks in the juices and adds a beautiful crust.
Bake to Perfection
Transfer the chicken to a baking dish and brush generously with melted garlic butter. Bake in a preheated oven at 375°F (190°C) for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).

The result? Perfectly cooked chicken with gooey cheese spilling out and a garlicky butter glaze that’s impossible to resist.

Storage Options

If you’re lucky enough to have leftovers, this dish stores beautifully!

Refrigerator: Store leftover chicken in an airtight container for up to 3 days.
Freezer: Wrap each piece in foil and place in a freezer-safe bag. Freeze for up to 2 months. Thaw in the fridge overnight before reheating.

To reheat, bake in a preheated oven at 350°F (175°C) until warmed through. Avoid microwaving as it can make the chicken rubbery and the filling less appealing.

Variations and Substitutions

One of the best things about this recipe is its versatility. Here are a few ideas to customize your Cheesy Garlic Butter Mushroom Stuffed Chicken:

Swap the Mushrooms: Not a fan of mushrooms? Try spinach or sun-dried tomatoes for a fresh twist.
Change the Cheese: Experiment with cheeses like Gouda, Fontina, or even blue cheese for a bold flavor.
Add Herbs: Fresh parsley, thyme, or rosemary in the garlic butter sauce can add depth to the dish.
Make It Spicy: Add a pinch of red pepper flakes to the filling for a little heat.
Go Low-Carb: Serve with cauliflower mash or zucchini noodles for a keto-friendly meal.
