Ingredients
Chicken
- 2 x 220g / 7oz chicken breasts, skinless boneless
- 3/4 tsp salt
- 1/4 tsp pepper
- 1 tbsp olive oil
Mushroom Filling
- 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
- 2 cups baby spinach
- 80g / 3oz mozzarella cheese, sliced (or other melting cheese)
Instructions
- Preheat Oven: Preheat your oven to 200°C/390°F (180°F fan) to prepare for baking the chicken.
- Create Chicken Pockets: Cut pockets into each chicken breast on the side with the fold, being careful not to cut all the way through to keep the smooth side intact.
- Season Chicken: Season both inside and outside of the chicken breasts with half of the salt and pepper.
- Prepare Mushroom Filling: Melt butter in a heavy-based ovenproof skillet over high heat. Add mushrooms and cook for 3 minutes until they start turning golden. Add garlic, thyme, remaining salt and pepper, then continue cooking for another 2 minutes until mushrooms are nicely golden.
- Add Spinach: Stir in baby spinach and cook until wilted, about 30 seconds.
- Stuff Chicken: Fill each chicken pocket with the mushroom and spinach mixture, then top with sliced mozzarella cheese.
- Seal Chicken: Use toothpicks to mostly seal the pockets, ensuring the filling stays inside without needing a full seal.
- Sear Chicken: Wipe the pan with paper towels, heat olive oil over medium-high heat, and sear each side of the chicken breast for 1 1/2 minutes until golden brown.
- Bake: Transfer the skillet to the preheated oven and bake for 15 minutes, or until the internal temperature of the chicken reaches 65°C/149°F (measure the chicken flesh, not the filling).
- Rest and Serve: Remove the chicken from the skillet onto a plate, loosely cover with foil, and let rest for 5 minutes before serving to allow juices to redistribute.
Notes
- Be careful not to cut through the chicken breasts completely when making the pockets.
- Searing the chicken before baking ensures a nice golden crust and locks in juices.
- Use an instant-read thermometer to check for doneness at 65°C/149°F for safe and juicy chicken.
- Substitute mozzarella with other melting cheeses like provolone or Monterey Jack if preferred.
- To prevent the toothpicks from burning in the oven, soak them in water for 10 minutes before use if desired.
