How to Make Mushroom Stuffed Chicken Breast

Prepare the Chicken

1. Preheat your oven to 200°C / 390°F (180°C fan).
2. Carefully cut a deep pocket into the side of each chicken breast without cutting all the way through.
3. Season the inside and outside of the chicken with salt and black pepper.

Tip: Aim for a wide pocket so you can add plenty of filling without tearing the meat.

Make the Mushroom Filling

1. In a heavy, oven-safe skillet, melt butter over high heat.
2. Add mushrooms and cook about 3 minutes until they begin to brown.
3. Stir in garlic, thyme, and remaining seasoning. Cook another 2 minutes until golden and fragrant.
4. Add spinach and stir just until wilted. Remove from heat.

Tip: Avoid overcrowding the pan so the mushrooms brown instead of steaming.

Stuff and Seal

1. Spoon the mushroom mixture into each chicken breast.
2. Add slices of mozzarella on top of the filling.
3. Secure the openings with toothpicks to keep the filling inside while cooking.

Sear the Chicken

1. Wipe out the skillet and heat olive oil over medium-high heat.
2. Sear the stuffed chicken breasts about 1½ minutes per side, until lightly golden.

Tip: Searing locks in juices and adds beautiful color before baking.

Bake

1. Transfer the skillet to the oven.
2. Bake for about 15 minutes, or until the internal temperature of the chicken reaches 74°C / 165°F.

Rest and Serve

1. Remove chicken from the oven and loosely cover with foil.
2. Let rest 5 minutes before serving to keep it juicy.

Serve warm and enjoy every tender, flavorful bite.

Tips for Success

• Pat chicken dry before seasoning to help it brown better.
• Don’t overfill the pockets; this helps prevent leaks.
• Let the chicken rest after baking so juices redistribute.
• Use an oven thermometer for perfectly cooked, juicy chicken.

Equipment Needed

• Sharp knife
