how to make Mushroom Stuffed Chicken Breast
Ingredients:
- 2 x 220g / 7oz chicken breast, skinless boneless (Note 1)
- 3/4 tsp salt
- 1/4 tsp pepper
- 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 (Note 2)
- 2 cups baby spinach (Note 3)
- 80g / 3oz mozzarella, sliced (or other melting cheese)
- 1 tbsp olive oil
Directions:
- Preheat oven to 200°C/390°F (180°F fan).
- Cut pockets into each chicken breast, being sure not to cut all the way through. Cut on the side with the fold in the meat to keep the smooth side intact.
- Season the inside and outside of the chicken with half the salt and pepper.
- For the mushroom filling, melt butter in a heavy-based oven-proof skillet over high heat. Add mushrooms and cook for 3 minutes until they start to turn pretty golden. Then add garlic, thyme, the remaining salt and pepper, and cook for another 2 minutes until mushrooms are nice and golden.
- Add baby spinach to the pan and stir until wilted—about 30 seconds.
- Stuff the mushroom mixture into the pocket of each chicken and top with cheese.
- Seal with toothpicks as best you can; it doesn’t need to be fully sealed.
- Wipe the pan quickly with paper towels. Heat oil over medium-high heat and sear each side of the chicken breast for 1.5 minutes until golden.
- Transfer the skillet to the oven and bake for 15 minutes, or until the internal temperature of the chicken is 65°C/149°F (chicken flesh, not the mushroom filling).
- Remove from the oven and let it rest for 5 minutes, loosely covered with foil. Serve!
