Tips & Variations
- Use a thermometer to ensure the chicken is cooked perfectly without drying out.
- Try swapping mozzarella for provolone or Swiss cheese for a different flavor.
- You can add chopped sun-dried tomatoes to the filling for a tangy twist.

Store any leftover stuffed chicken breasts in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently in the oven at 160°C / 320°F until heated through to maintain juiciness. Avoid microwaving if possible to prevent dryness.

Stuffing
- 30g / 2 tbsp unsalted butter
- 200g / 7 oz mushrooms, sliced 3mm (1/8″) thick (~2 heaped cups)
- 2 garlic cloves, finely minced
- 1/2 tsp thyme leaves

- 80g / 3oz mozzarella, sliced (or other melting cheese)
Cooking
- 1 tbsp olive oil
Instructions
- Preheat Oven: Preheat your oven to 200°C/390°F (180°F fan) to prepare for baking the stuffed chicken.
- Prepare Chicken Pockets: Cut pockets into each chicken breast on the side with the fold in the meat, ensuring not to cut all the way through, keeping the smooth side intact for stuffing.
- Season Chicken: Season both inside and outside of the chicken breasts with half of the salt and pepper to enhance flavor throughout.
- Cook Mushroom Filling: Melt butter in a heavy-based oven-proof skillet over high heat. Add mushrooms and cook for 3 minutes until they begin to turn golden. Add minced garlic, thyme, and remaining salt and pepper, cooking for another 2 minutes until mushrooms are fully golden.
- Add Spinach: Stir in the baby spinach into the mushroom mixture and cook until wilted, about 30 seconds, melding flavors together.
- Stuff Chicken: Fill each chicken breast pocket with the mushroom and spinach mixture, then place sliced mozzarella cheese on top of the filling.
- Seal Chicken: Seal the pockets mostly with toothpicks to hold the stuffing in place, without needing a perfect seal like Chicken Kiev.
- Sear Chicken: Wipe the skillet clean, heat olive oil over medium-high heat, and sear each side of the stuffed chicken breasts for 1 1/2 minutes until golden brown, creating a flavorful crust.
- Bake in Oven: Transfer the skillet with the seared chicken breasts to the preheated oven and bake for 15 minutes or until the internal chicken temperature reaches 65°C/149°F, ensuring the chicken is fully cooked but juicy.
- Rest and Serve: Remove chicken from the skillet, place on a plate, cover loosely with foil, and let rest for 5 minutes before serving to allow juices to redistribute for maximum tenderness.
Notes
- Use fresh mushrooms for best flavor and texture in the stuffing.
- Ensure not to cut through the chicken breasts when creating pockets to keep the stuffing inside.
- Resting the chicken allows juices to redistribute, making the chicken moist and tender.
- Internal temperature of 65°C/149°F ensures safe consumption while maintaining juiciness.
- You can substitute mozzarella with any good melting cheese like provolone or fontina.
- Serve with creamy baked lemon herb risotto and baby spinach with balsamic dressing for a complete meal.
