Ingredients

Scale

For the Chicken:

  • 3/4 tsp salt
  • 2 boneless, skinless chicken breasts (7 oz each)
  • 1/4 tsp black pepper

For the Mushroom Stuffing:

  • 2 tbsp unsalted butter
  • 7 oz mushrooms, sliced (about 1/8″ thick)
  • 2 cloves garlic, freshly minced
  • 1/2 tsp thyme leaves
  • 2 cups fresh baby spinach (steamed and squeezed dry)
  • 3 oz mozzarella cheese, sliced (low-moisture part-skim preferred)

For Cooking:

  • 1 tbsp olive oil (or neutral oil like canola)

Instructions

  1. Preheat Oven and Prepare Chicken: Preheat your oven to 200°C (390°F) or 180°C fan-forced. Carefully cut a pocket into the side of each chicken breast without cutting all the way through. Season the inside and outside of each breast with half of the salt and pepper.
  2. Prepare the Mushroom Filling: In a heavy-based, oven-proof skillet, melt the butter over high heat. Add sliced mushrooms and cook for about 3 minutes until they start turning golden. Add minced garlic, thyme leaves, and the remaining salt and pepper, cooking for another 2 minutes until the mushrooms are golden. Stir in the steamed baby spinach and cook until wilted, about 30 seconds.
  3. Stuff and Seal the Chicken: Stuff each chicken breast pocket with the mushroom mixture, then top with slices of mozzarella cheese. Use toothpicks to mostly seal the openings to keep the filling inside during cooking.
  4. Sear the Chicken: Wipe the skillet clean with paper towels and heat olive oil over medium-high heat. Sear each side of the stuffed chicken breasts for about 1.5 minutes until golden brown.
  5. Bake the Chicken: Transfer the skillet with the seared chicken breasts to the preheated oven. Bake for 15 minutes or until the internal temperature of the chicken reaches 65°C (149°F), measuring in the thickest part of the chicken.
  6. Rest and Serve: Remove chicken from the oven and place on a plate. Loosely cover with foil and let rest for 5 minutes before serving. Serve warm, paired with creamy baked lemon herb risotto and a side of baby spinach with balsamic dressing for a complete meal.

Notes

  • Be careful not to cut all the way through the chicken when making the pocket to prevent the filling from leaking out.
  • Using low-moisture part-skim mozzarella helps avoid excess moisture and creates a better texture.
  • Measure the internal temperature of the chicken, not the stuffing, to ensure proper doneness.
  • Allowing the chicken to rest helps retain juices for a moist, tender result.
  • Toothpicks are optional but help keep the filling intact during cooking.
