Ingredients You Need

Chicken

• 4 medium boneless skinless chicken breasts
  • Choose thicker pieces so you can slice a pocket easily.
  • If the chicken looks very large, plan to cut each cooked breast in half for serving.

Mushroom garlic filling

• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 8 ounces cremini or baby bella mushrooms, finely sliced
  • White button mushrooms also work, they just taste a little milder.
• 4 cloves garlic, minced
• 1 teaspoon Italian seasoning
• 1 teaspoon fresh thyme leaves or 1/2 teaspoon dried thyme
• 1/2 teaspoon onion powder
• 1/2 teaspoon kosher salt, plus more to taste
• 1/4 teaspoon black pepper

Cheesy stuffing

• 3/4 cup shredded mozzarella cheese
  • Use low moisture, part skim for better melt and less grease.
• 1/4 cup grated Parmesan cheese
  • Pre-grated works fine, but fresh grated tastes sharper.
• 2 tablespoons softened cream cheese
  • This helps the filling stay creamy and not leak out.
• 1 tablespoon chopped fresh parsley (optional, for color and freshness)

Chicken seasoning

• 1 tablespoon olive oil
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper
• 1 teaspoon smoked or sweet paprika
• 1 teaspoon garlic powder
• 1/2 teaspoon onion powder

Garlic butter for cooking

• 2 tablespoons unsalted butter
• 2 cloves garlic, minced or grated
• 1 tablespoon olive oil
• Juice of 1/2 lemon (about 1 tablespoon)
• 1/4 cup low sodium chicken broth
  • You can use water with 1/4 teaspoon bouillon powder as a shortcut.

Optional garnish

• Extra chopped parsley
• Extra grated Parmesan

Equipment

• Large oven-safe skillet (cast iron or stainless steel)
• Sharp knife and cutting board
• Small mixing bowl for the cheese filling
• Spoon or small spatula for stuffing
• Toothpicks to secure the chicken pockets
• Instant-read thermometer for perfect doneness

Tips & Mistakes

• Slice the chicken pocket slowly and stop before you cut through the other side.
• Pat the chicken dry so the seasoning sticks and the outside browns nicely.
• Do not overstuff the chicken; leave a little space so the cheese does not spill out.
• Secure the open side with 2 to 3 toothpicks so the filling stays inside.
• Cook the mushrooms until they release liquid and that liquid cooks off, or the filling turns watery.
• Let the mushroom mixture cool slightly before you mix in the cheese so it does not turn greasy.
• Season the outside of the chicken well; bland chicken ruins great filling.
• Sear the chicken on medium heat, not high heat, so the outside browns without burning.
• Move the skillet to the oven once the outside looks golden so the inside cooks gently and stays juicy.
• Check the internal temperature and pull the chicken at 165°F in the thickest part.
• Let the chicken rest 5 to 7 minutes before slicing so the juices stay inside.
• Remove toothpicks before serving so nobody crunches into a surprise.

How to Make Cheesy Garlic Butter Mushroom Stuffed Chicken Recipe

Prep the chicken

1. Lay the chicken breasts on a cutting board and pat them dry with paper towels.
2. Place your hand flat on top of one breast and use a sharp knife to slice a pocket horizontally from the thicker side, stopping about 1/2 inch from the other edge.
3. Repeat with the remaining chicken breasts and set them aside.

Cook the mushroom garlic mixture

4. Heat 2 tablespoons butter and 1 tablespoon olive oil in a large skillet over medium heat.
5. Add the sliced mushrooms and cook, stirring often, until they soften and release their liquid, about 5 to 7 minutes.
6. Add the minced garlic, Italian seasoning, thyme, onion powder, salt, and pepper, then cook 1 to 2 minutes until fragrant and most liquid evaporates.
7. Taste and adjust salt if needed, then transfer the mushroom mixture to a plate and let it cool for about 5 minutes.

Mix the cheesy filling

8. In a small bowl, combine mozzarella, Parmesan, cream cheese, and parsley.
9. Stir until the mixture looks smooth and evenly combined.
10. Add the cooled mushroom mixture to the bowl and mix until everything distributes evenly.

Stuff and season the chicken

11. Spoon the cheesy garlic mushroom filling into each chicken pocket, dividing it evenly.
12. Press the edges together and secure each breast with 2 to 3 toothpicks along the opening.
13. In a small dish, mix salt, pepper, paprika, garlic powder, and onion powder.
14. Rub 1 tablespoon olive oil over the outside of the chicken, then sprinkle the seasoning mix all over both sides.

Sear the stuffed chicken

15. Preheat your oven to 375°F.
16. In the same skillet, heat 2 tablespoons butter and 1 tablespoon olive oil over medium heat.
17. Add the minced garlic for the garlic butter and cook about 30 seconds, just until fragrant.
18. Place the stuffed chicken breasts in the skillet and sear 3 to 4 minutes per side until golden brown.

Finish in the oven

19. Add chicken broth and lemon juice to the skillet around the chicken.
20. Spoon some of the garlicky butter mixture over the tops of the chicken.
21. Transfer the skillet to the oven and bake 12 to 18 minutes, depending on thickness, until the internal temperature reaches 165°F.
22. Remove the skillet from the oven and let the chicken rest in the pan for 5 to 7 minutes.

Slice and serve

23. Remove the toothpicks carefully.
24. Spoon some of the pan juices over the chicken.
25. Slice each breast into thick pieces so the cheesy garlic mushroom filling shows.
26. Sprinkle with extra parsley and Parmesan if you like, then serve hot.

Variations I've Tried

• Spinach mushroom version: Add 1 cup chopped fresh spinach to the skillet during the last minute of cooking the mushrooms, then stir until it wilts and mix it into the cheese filling.
• Bacon mushroom version: Cook 3 to 4 slices of chopped bacon in the skillet first, remove the bacon, then cook the mushrooms in some of the bacon fat and mix the crisp bits into the filling.
• Spicy kick version: Add 1/2 teaspoon red pepper flakes to the mushroom mixture and use pepper jack cheese in place of mozzarella.
• Herb lover version: Swap Italian seasoning for a mix of fresh basil, parsley, and chives, and add extra lemon zest to brighten the flavor.

How to store

• Fridge: Cool leftovers completely, then store in an airtight container in the refrigerator for up to 3 to 4 days.
