Notes

Ingredients

2 boneless, skinless chicken breasts (about 220g/7oz each)
¾ teaspoon salt
¼ teaspoon black pepper
2 tablespoons (30g) unsalted butter
200g (7oz) mushrooms, sliced (about 2 heaping cups)
2 garlic cloves, minced
½ teaspoon dried thyme (or fresh thyme leaves)
2 cups baby spinach
80g (3oz) mozzarella cheese, sliced (or any melting cheese)
1 tablespoon olive oil

Instructions

Preheat the oven to 200°C (390°F) or 180°C (fan-forced).
Prepare the chicken: Slice a pocket into each chicken breast, being careful not to cut all the way through. Season both the inside and outside of the chicken with half of the salt and pepper.
Make the mushroom filling:
- Heat butter in an ovenproof skillet over high heat.
- Add mushrooms and cook for about 3 minutes until golden.
- Stir in the garlic, thyme, and remaining salt and pepper, cooking for another 2 minutes.
- Add baby spinach and stir until wilted (about 30 seconds).
Stuff the chicken: Fill each chicken pocket with the mushroom-spinach mixture and top with cheese. Secure with toothpicks if needed.
Sear the chicken:
- Wipe the skillet clean and heat olive oil over medium-high heat.
- Sear the chicken for about 1½ minutes per side until golden brown.
Bake: Transfer the skillet to the oven and bake for 15 minutes, or until the internal temperature of the chicken reaches 65°C (149°F).
Rest & Serve: Remove the chicken from the oven, cover loosely with foil, and let it rest for 5 minutes before serving.

Notes:

Chicken breast is ideal for this recipe since it holds the filling well. Other cuts like thighs won’t work the same way.
Herb substitutes: You can swap thyme for dried oregano, rosemary, or parsley.
Vegetable variations: Instead of baby spinach, try chopped kale, Swiss chard, or even shredded cabbage.

1. How do I properly cut a pocket in the chicken breast for stuffing?
Lay the chicken breast flat and, using a sharp knife, make a horizontal incision along the thicker side, being careful not to cut all the way through. This method creates ample space for the filling while preventing leaks during cooking.

2. What can I use to secure the filling inside the chicken breast?
Toothpicks work well to keep the stuffed chicken breast closed during cooking. Insert them near the opening to hold the edges together, ensuring the filling stays intact. Just remember to remove all toothpicks before serving.

3. How can I prevent the chicken from drying out during cooking?
Using a meat thermometer is key. Bake the chicken until it reaches an internal temperature of 165°F (74°C). Overcooking can lead to dryness, so monitoring the temperature ensures juiciness.

4. Are there alternative fillings I can use?
Absolutely! While mushrooms and spinach are classic choices, you can experiment with other fillings like sun-dried tomatoes, different cheeses, or sautéed vegetables to suit your taste.

5. Can I prepare the stuffed chicken breasts in advance?
Yes! You can assemble the stuffed chicken breasts a day ahead and refrigerate them. When ready to cook, let them sit at room temperature for about 15 minutes before baking to ensure even cooking.
