• 4 skinless, boneless chicken breasts
• Salt & pepper, to season
• 1 teaspoon onion powder

• ¼ cup fresh grated Parmesan cheese

• 1 tablespoon olive oil
• 2 large garlic cloves, minced
• 1 tablespoon Dijon mustard

How to Make Cheesy Garlic Butter Mushroom Stuffed Chicken

This dish comes together in a few simple steps, but every step adds depth and flavor.

1. Prepare the Mushroom Filling

Start by melting butter in a large, oven-safe skillet. Add minced garlic and sauté until fragrant. Add sliced mushrooms, parsley, salt, and pepper, and cook until tender. These mushrooms are incredibly flavorful and form the rich, savory base of the stuffing.

2. Prepare the Chicken

Pat the chicken dry and season generously with salt, pepper, onion powder, and dried parsley. Slice a pocket into each chicken breast and stuff it with mozzarella slices, a spoonful of mushrooms, and a sprinkle of Parmesan. Secure with toothpicks — this keeps all that goodness from spilling out during cooking.

3. Sear and Bake

Use the same skillet you cooked the mushrooms in — it’s already infused with flavor. Sear the stuffed chicken on both sides until golden brown. Cover and transfer the skillet to a preheated 400°F oven. Bake for about 20 minutes, or until the chicken is fully cooked.

4. Make the Creamy Garlic Parmesan Sauce

Once the chicken is done, remove it from the skillet. Add more garlic to the pan juices and sauté. Stir in Dijon mustard, half and half, remaining mushrooms, and Parmesan. If you prefer a thicker sauce, add the optional cornstarch slurry. Finish with fresh parsley.

Return the chicken to the pan and spoon that silky sauce over the top.

Tips for Perfect Stuffed Chicken

🧀 Use good-quality cheese. Fresh mozzarella melts beautifully and helps create that signature cheesy pull.
🍄 Don’t overcrowd the mushrooms. Let them cook down properly for deeper flavor.
🔥 Use an oven-safe skillet. This allows you to sear and bake in one pan.
🔪 Cut chicken pockets carefully. Keep the sides intact so the filling doesn’t escape.
⏱️ Let the chicken rest. Just a few minutes helps keep the meat juicy.

What to Serve With Mushroom Stuffed Chicken

This dish pairs wonderfully with:

• Garlic mashed potatoes
• Buttered noodles or fettuccine
• Steamed or roasted broccoli
• Sautéed spinach
• Herb rice or risotto
• A crisp Caesar or garden salad

The creamy sauce tastes amazing drizzled over sides!

Storage and Reheating Tips

• Store: Keep leftovers in an airtight container for up to 3 days.
• Reheat: Warm gently on the stovetop or in the oven at 325°F to maintain juiciness.
• Freezing: You can freeze the cooked chicken (without the sauce) for up to 2 months. Reheat and add freshly made sauce.
