How to Make Cheesy Garlic Butter Mushroom Stuffed Chicken

Prep the Filling First

Start by making the flavorful mushroom filling. In a skillet, melt 4 tablespoons of butter over medium heat. Add 8 ounces of sliced brown mushrooms and cook them down until they release their moisture and become golden brown about 5–7 minutes. Add 4 cloves of minced garlic, 2 tablespoons of chopped fresh parsley, and a pinch of salt and pepper. Sauté everything together for another 1–2 minutes until fragrant.

Here’s the key: Don’t rush this part. Mushrooms hold a lot of water, and if they’re not fully cooked down, your cheesy garlic butter mushroom stuffed chicken can turn soggy. Once done, set the filling aside to cool slightly while you prepare the chicken.

Stuff, Sear, and Bake to Perfection

Now let’s get to the star of the show. Use 4 skinless, boneless chicken breasts. Slice a pocket into the side of each breast without cutting all the way through. Season both sides with salt, pepper, onion powder, and dried parsley.

Stuff each pocket with a spoonful of the mushroom mix, then add 2 slices of mozzarella and a sprinkle of parmesan cheese. Secure the openings with toothpicks if needed.

In an oven-safe skillet, heat a bit of olive oil and sear the chicken on both sides until golden about 3 minutes per side. Then transfer the skillet to a preheated oven at 375°F and bake for 15–20 minutes, or until the internal temperature hits 165°F.

Once out of the oven, let the chicken rest for 5 minutes. This helps the juices redistribute and keeps your filling from spilling out the moment you cut in.

Garlic Parmesan Sauce & Expert Tips for Perfect Results

The Signature Garlic Parmesan Cream Sauce

While the chicken bakes, it’s time to make the sauce that brings this whole dish together. Don’t wipe out the skillet! Those golden, caramelized bits left from searing the chicken are flavor gold.

Here’s how to make the sauce in just a few steps:

1. In the same pan, heat a tablespoon of olive oil.
2. Add minced garlic and sauté until fragrant (about 30 seconds).
3. Stir in Dijon mustard and pour in half-and-half or cream.
4. Whisk gently, then add parmesan cheese and season with salt and pepper.
5. Let the sauce simmer for a few minutes until slightly thickened.
6. Optional: Add a cornstarch slurry (½ tsp cornstarch + 2 tsp water) for extra body.
7. Finish with freshly chopped parsley and spoon over the chicken to serve.

Let the sauce thicken slightly before spooning it over the chicken the result is rich, velvety, and ties every element of the meal together.

Pro Tips to Avoid Common Mistakes

These quick expert insights can help you avoid the most frequent pitfalls and make sure your dish turns out beautifully every single time:

• Don’t skip searing. It locks in moisture and adds depth of flavor before baking.
• Use a meat thermometer. Pull your chicken at exactly 165°F to prevent dryness.
• Avoid cutting too deep. Make a pocket, not a flap. This holds the filling in place.
• Let the mushrooms cook down fully. Wet filling = soggy results.
• Let the chicken rest. A 5-minute rest keeps it juicy and stops the cheese from leaking.
• Cut against the grain when slicing. It makes the meat more tender and easier to serve.
• Short on time? Prep and stuff the chicken ahead, refrigerate, and cook when ready.
• Use toothpicks to secure if needed. Especially if overstuffing this dish.
