Ingredients You Need

Chicken

4 boneless skinless chicken breasts, medium size, about 6 to 7 ounces each
1 to 1½ teaspoons kosher salt, divided
½ teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon Italian seasoning or dried mixed herbs

Mushroom filling

2 tablespoons olive oil or avocado oil
1 tablespoon unsalted butter, optional but adds flavor
8 ounces cremini or baby bella mushrooms, finely chopped
- White button mushrooms also work, they just taste a bit milder.
½ small yellow onion, finely diced
3 cloves garlic, minced (use jarred minced garlic if you like shortcuts)
½ teaspoon kosher salt
¼ teaspoon black pepper
½ teaspoon dried thyme or Italian seasoning
¼ teaspoon red pepper flakes, optional for a little heat
2 tablespoons fresh parsley, chopped, plus more for garnish
3 ounces cream cheese, softened
- Use full fat or light; both work.
½ cup shredded mozzarella cheese
- Pre shredded mozzarella works fine, but fresh shredded melts smoother.
¼ cup grated Parmesan cheese
- Shelf stable grated Parmesan works, but real Parmigiano or Grana Padano tastes better.

For searing and finishing

1 to 2 tablespoons olive oil
1 tablespoon butter, optional
½ cup low sodium chicken broth
Juice of ½ lemon, optional but brightens the sauce

Equipment

Sharp chef’s knife
Cutting board
Large skillet that goes in the oven (cast iron or stainless steel)
Small mixing bowl
Spoon or small spatula
Toothpicks or small skewers to secure the chicken
Instant read thermometer, very helpful for juicy chicken

Quick Tips & substitutions

Pat the chicken dry so it browns well and holds the seasoning.
Slice a pocket in the thick side of each breast and stop about ½ inch from the other side so the filling stays inside.
Use finely chopped mushrooms so they cook fast and fit easily in the chicken.
Swap cream cheese with Boursin or herbed goat cheese for extra flavor.
Use pre sliced mushrooms and pre minced garlic to save prep time.
Choose low moisture mozzarella so the filling stays thick and not watery.
Season the mushroom mixture generously; bland filling means bland chicken.
Do not overstuff the chicken; leave a little space so the filling does not spill out.
Secure the opening with 2 to 3 toothpicks per breast to keep the filling in place.
Sear the stuffed chicken in a hot skillet, then finish in the oven for juicy results.
Pull the chicken at 160 to 162°F internal temperature; it will reach 165°F as it rests.
Use chicken thighs instead of breasts if you prefer darker meat; adjust cook time slightly.

How to Make Mushroom Stuffed Chicken Breast Recipe

Prep the chicken

Use a sharp knife and slice a deep pocket in each chicken breast. Start at the thickest side and cut horizontally, keeping the knife parallel to the cutting board. Stop before you cut all the way through so the breast stays in one piece.

Season the outside and inside of each pocket with salt, pepper, garlic powder, onion powder, and Italian seasoning. Set the chicken aside while you cook the filling so the seasoning starts to work into the meat.

Cook the mushroom filling

Heat olive oil and butter in a large skillet over medium high heat. Add the chopped mushrooms and onion, then spread them in an even layer. Let them cook without stirring for 2 to 3 minutes so they brown.

Stir and cook the mushrooms and onion until they release their moisture and the pan looks mostly dry. Add garlic, salt, pepper, thyme, and red pepper flakes. Cook 1 to 2 minutes until the garlic smells fragrant.

Turn the heat to low. Stir in cream cheese, mozzarella, and Parmesan until the mixture turns creamy and thick. Add chopped parsley, taste, and adjust salt or pepper if needed. Transfer the filling to a bowl and let it cool for 5 to 10 minutes so it thickens more.

Stuff the chicken

Spoon the cooled mushroom mixture into each chicken pocket. Press the filling in gently with the back of the spoon so it reaches the back of the pocket. Use toothpicks to pin the open side closed.

Season the outside again lightly with a pinch of salt and pepper if needed. You want good flavor on the crust as well as inside.

Sear the stuffed chicken

Wipe out the skillet if needed, then add a little more oil and butter over medium high heat. When the fat shimmers, place the stuffed chicken breasts in the skillet. Lay them in carefully so you do not knock out the filling.

Sear each side for about 3 to 4 minutes until the chicken turns golden brown. Turn the chicken gently with tongs and keep the heat at medium to medium high so it browns but does not burn.

Finish in the oven

Heat your oven to 375°F while you sear the chicken. After both sides look golden, pour chicken broth into the skillet around the chicken. Add lemon juice if you like a bright, light sauce.

Move the skillet to the oven and bake for 12 to 18 minutes, depending on thickness. Check the internal temperature in the thickest part of the chicken, not the filling. Pull the chicken when it reaches about 160 to 162°F.

Let the chicken rest in the skillet for 5 to 8 minutes. The temperature will rise to 165°F, and the juices will redistribute so the meat stays moist. Spoon a little of the pan juices over the top before serving.
