Ingredients
Method
- Prepare the Chicken: Lay your chicken breasts on a clean cutting board. Using a sharp knife, carefully slice a deep pocket into the thickest part of each chicken breast, being careful not to cut all the way through the sides or ends. You want to create a space for the generous filling. Place each chicken breast between two pieces of plastic wrap. Using a meat mallet or the bottom of a heavy pan, pound the chicken gently until it's about 1/2 to 3/4 inch thick. This ensures even cooking and creates more surface area for the stuffing. Season both sides of the pounded chicken generously with salt, pepper, and optional paprika.
- Make the Mushroom Filling: Heat 2 tablespoons of butter in a large skillet over medium heat. Add the finely chopped mushrooms and minced garlic. Sauté for 5-7 minutes, stirring occasionally, until the mushrooms are tender and have released most of their liquid. Remove the skillet from the heat and let the mushroom mixture cool slightly.
- Combine the Filling: In a medium bowl, combine the cooled mushroom mixture, softened cream cheese, shredded mozzarella cheese, grated Parmesan cheese, and chopped fresh parsley. Mix everything together thoroughly until well combined.
- Stuff the Chicken: Take one pounded chicken breast. Spoon about 1/4 of the mushroom and cheese mixture onto one half of the chicken. Fold the other half of the chicken over the filling, creating a crescent shape. Gently press the edges together to seal the stuffing inside. If needed, secure the edges with toothpicks to prevent the filling from escaping during cooking. Repeat with the remaining chicken breasts and filling.
- Sear the Chicken: Heat 1 tablespoon of olive oil in an oven-safe skillet (cast iron works wonderfully) over medium-high heat. Once hot, carefully place the stuffed chicken breasts into the skillet. Sear for 3-4 minutes per side until beautifully golden brown.
- Bake to Perfection: Transfer the oven-safe skillet with the seared chicken to a preheated oven at 375°F (190°C). Bake for 15-20 minutes, or until the internal temperature of the thickest part of the chicken reaches 165°F (74°C) on an instant-read thermometer. The cheese inside will be wonderfully melty and gooey.
- Rest and Serve: Once baked, remove the skillet from the oven. Let the Cheesy Garlic Butter Mushroom Stuffed Chicken rest for 5-10 minutes before slicing. This allows the juices to redistribute, ensuring tender and moist chicken. Remove any toothpicks before serving. Drizzle with any pan juices, if desired, and garnish with extra fresh parsley. Enjoy this magnificent Cheesy Garlic Butter Mushroom Stuffed Chicken!
Notes
Pound chicken breasts to an even thickness (1/2 to 3/4 inch) for uniform cooking.
Don't overstuff to prevent cheese leakage; use about 1/4 cup filling per breast.
Secure edges with wooden toothpicks if needed, remembering to remove them before serving.
Allow sautéed mushroom mixture to cool slightly before mixing with cheeses to prevent it from becoming too runny.
Searing creates a golden-brown crust and locks in juices.
Use an oven-safe skillet or transfer seared chicken to a baking dish.
Avoid overcooking; use an instant-read thermometer to reach 165°F (74°C).
Rest chicken for 5-10 minutes after baking for juicier results.
Leftovers store in an airtight container in the refrigerator for 3-4 days.
Cooked chicken can be frozen for 2-3 months, thaw before reheating.
Uncooked, stuffed chicken can be frozen for 1 month, thaw completely before cooking.
To reheat, use oven at 325°F (160°C) for 15-20 minutes (covered with foil) or microwave for 1-2 minutes, ensuring 165°F (74°C) internal temperature.
Prep stuffing up to a day ahead, or stuff chicken up to 24 hours ahead; bring to room temperature before cooking.
Thicker chicken breasts are ideal for stuffing.
