Ingredients You’ll Need

Chicken

• 4 medium boneless skinless chicken breasts
  • Choose thicker breasts so you can slice a pocket without cutting through.
• 1 teaspoon kosher salt
• ½ teaspoon black pepper
• ½ teaspoon smoked paprika or regular paprika
• ½ teaspoon garlic powder

Mushroom & Garlic Butter Filling

• 2 tablespoons unsalted butter
  • Use salted butter if you like, then reduce added salt slightly.
• 1 tablespoon olive oil
• 8 ounces cremini or baby bella mushrooms, finely sliced
  • White button mushrooms also work, but cremini bring deeper flavor.
• 4 cloves garlic, minced
• ½ teaspoon Italian seasoning or dried oregano + dried basil mix
• ¼ teaspoon crushed red pepper flakes (optional, for a mild kick)
• ¼ teaspoon salt, more to taste
• Freshly ground black pepper, to taste

Cheese

• 1 cup shredded mozzarella cheese
  • Pre-shredded works, but fresh shredded melts smoother.
• ½ cup shredded Parmesan cheese
  • Use real Parmigiano Reggiano or a good domestic parmesan, not the green can.
• 2 ounces cream cheese, softened
  • This adds extra creaminess and helps the filling stay put.

Garlic Butter Basting Sauce

• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 2 cloves garlic, minced
• ¼ cup chicken broth or stock
• 1 tablespoon fresh parsley, chopped (or 1 teaspoon dried parsley)
• Juice of ½ lemon (about 1 tablespoon)

Optional Garnishes

• Extra chopped parsley
• Extra grated Parmesan
• Lemon wedges

Equipment

• Large oven-safe skillet (cast iron or stainless steel works great)
• Cutting board and sharp knife
• Small mixing bowl
• Tongs
• Toothpicks or small skewers to secure the stuffed chicken
• Meat thermometer (helps you avoid dry chicken)

Tips & Tricks

• Slice chicken pockets carefully and stop about ½ inch from the edge so the filling stays inside.
• Pat chicken dry with paper towels so seasoning sticks and browning happens nicely.
• Use room temperature cream cheese so it mixes smoothly with the other cheeses.
• Chop mushrooms small so they fit easily inside the chicken and cook evenly.
• Cook mushrooms until they release moisture and turn golden so the filling tastes rich, not watery.
• Let the mushroom mixture cool slightly before mixing with cheese so it does not melt the cheese into soup.
• Season both the outside and inside of the chicken for maximum flavor.
• Do not overstuff the chicken; leave a little space so the filling does not spill out while cooking.
• Secure the opening with toothpicks and insert them horizontally so you can sear both sides easily.
• Sear the stuffed chicken on medium heat so the outside browns without burning while the inside cooks through.
• Finish the chicken in the oven if the breasts feel thick; this keeps the outside from over-browning.
• Baste the chicken with the garlic butter sauce during the last few minutes for extra flavor and shine.
• Check doneness with a meat thermometer; pull chicken at 165°F in the thickest part.
• Let the chicken rest 5 minutes before slicing so juices redistribute and stay inside.
• Use leftover filling as a quick topping for toast or a baked potato if you have extra.

How to Make Cheesy Garlic Butter Mushroom Stuffed Chicken Recipe

Prep the Chicken

1. Place the chicken breasts on a cutting board and pat them dry with paper towels.
2. Hold a sharp knife parallel to the board and slice a pocket into the thickest side of each breast.
3. Stop about ½ inch from the opposite side so you do not cut through.
4. Season the outside and inside of each pocket with salt, pepper, paprika, and garlic powder.

Cook the Mushrooms

1. Heat 2 tablespoons butter and 1 tablespoon olive oil in a large skillet over medium heat.
2. Add the sliced mushrooms and spread them into an even layer.
3. Let them cook without stirring for 2 to 3 minutes so they brown.
4. Stir and continue cooking until the mushrooms release their liquid and turn golden, about 5 to 7 minutes total.

Build the Garlic Mushroom Filling

1. Add minced garlic, Italian seasoning, crushed red pepper flakes, salt, and pepper to the mushrooms.
2. Cook 1 to 2 minutes until the garlic smells fragrant and the mixture thickens slightly.
3. Taste and adjust seasoning; you want a bold, savory flavor here.
4. Transfer the mushroom mixture to a bowl and let it cool for 5 minutes.

Mix the Cheesy Center

1. Add mozzarella, Parmesan, and softened cream cheese to the bowl with the cooled mushrooms.
2. Stir until the cheeses and mushrooms combine into a thick, scoopable mixture.
3. If the mixture feels too stiff, add 1 tablespoon chicken broth to loosen it slightly.
4. If it feels too loose, add a little extra shredded mozzarella.

Stuff the Chicken

1. Spoon the cheesy garlic mushroom mixture into each chicken pocket.
2. Press the filling gently inside and spread it evenly from end to end.
3. Use toothpicks to secure the open side of each breast so the filling stays inside.
4. Set the stuffed chicken on a plate while you prep the skillet again.

Sear the Stuffed Chicken

1. Wipe out the skillet lightly if it holds any burnt bits, but keep the flavorful browned bits.
2. Add 1 tablespoon olive oil and heat over medium to medium-high.
3. Place the stuffed chicken breasts in the skillet, smooth side down.
4. Sear 4 to 5 minutes until the surface turns deep golden.

Flip and Start the Garlic Butter Sauce

1. Flip each chicken breast carefully with tongs.
2. Add 2 tablespoons butter and the minced garlic for the sauce to the skillet around the chicken.
3. Let the butter melt and stir the garlic into it so it cooks gently.
4. Pour in the chicken broth and scrape up any browned bits from the bottom of the pan.

Finish in the Oven

1. Preheat your oven to 375°F if you have not already.
2. Spoon some of the garlic butter sauce over the tops of the chicken.
3. Transfer the skillet to the oven and bake 10 to 15 minutes, depending on thickness.
4. Check with a meat thermometer; pull the chicken when the center reaches 165°F.

Rest and Serve

1. Remove the skillet from the oven and squeeze lemon juice over the chicken.
2. Baste the chicken again with the pan sauce for extra flavor.
3. Let the chicken rest 5 minutes on a cutting board or in the skillet.
4. Sprinkle with chopped parsley and extra Parmesan, then slice and serve with more sauce spooned over the top.
