How to Make Mushroom Stuffed Chicken Breast
Ingredients:
- 2 x 220g / 7oz chicken breasts, 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 / 3 oz mozzarella, sliced (or other melting cheese)
- 1 tbsp olive oil
Directions:
- Preheat your oven to 200°C/390°F (180°F fan).
- Cut pockets into each chicken breast, being careful not to cut all the way through. Cut on the side with the fold in the meat, keeping 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 the mushrooms and cook for 3 minutes until they start to turn golden. Then add garlic, thyme, and the remaining salt and pepper. Continue cooking for another 2 minutes until the mushrooms are nicely golden.
- Add the baby spinach to the skillet and stir until wilted, which takes about 30 seconds.
- Stuff the mushroom mixture into the pocket of each chicken. Top with cheese. Seal them with toothpicks as best as you can.
- Wipe the pan 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 reaches 65°C/149°F.
- Remove the chicken from the oven and place it on a plate. Loosely cover it with foil and let it rest for 5 minutes before serving.
This dish pairs beautifully with creamy baked lemon herb risotto and a fresh baby spinach salad with balsamic dressing.
