Ingredients
For the Chicken:
2 chicken breasts (220g or 7oz each, skinless and boneless)
3/4 teaspoon salt
1/4 teaspoon black pepper
2 tablespoons unsalted butter (30g)
7 oz mushrooms, sliced about 1/8″ thick (approximately 2 full cups, 200g)
2 cloves garlic, finely minced
1/2 teaspoon thyme leaves
2 cups fresh baby spinach
3 oz mozzarella cheese, sliced (or any cheese that melts well, 80g)
1 tablespoon olive oil
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Directions
Step 1: Preheat Oven and Prepare Chicken
Preheat your oven to 200°C/390°F (or 180°C fan-forced).
Using a sharp knife, carefully cut a pocket into each chicken breast on the side with the fold. Be careful not to cut all the way through – aim for a 3-4 inch wide pocket that doesn’t go all the way through the chicken.
Season both the inside and outside of each chicken breast with half of the salt and pepper.
Step 2: Prepare the Mushroom Filling
Heat 2 tablespoons butter in a heavy-based, oven-proof skillet over medium-high heat.
Add the sliced mushrooms and cook for about 3 minutes until they start to become golden.
Add the minced garlic, thyme leaves, and the remaining salt and pepper. Cook for another 2 minutes until the mushrooms are golden and fragrant.
Add the baby spinach to the skillet and cook until it wilts, which should take about 30 seconds.
Step 3: Stuff and Seal the Chicken
Stuff each chicken breast pocket with the mushroom mixture.
Top the mushroom filling with slices of mozzarella cheese.
Use toothpicks to seal the chicken breasts. It’s not necessary to seal them completely—just enough to hold the filling in.
Step 4: Sear the Chicken
Wipe the skillet with a paper towel to clean it, then heat 1 tablespoon olive oil in the same skillet over medium-high heat.
Add the stuffed chicken breasts and sear each side for about 1 to 1.5 minutes or until golden brown.
Step 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. Be sure to measure the temperature of the chicken, not the filling.
Step 6: Rest and Serve
Once the chicken is cooked, remove it from the oven and place it onto a plate.
Loosely cover the chicken with foil and let it rest for about 5 minutes before serving.
What to Serve With Stuffed Chicken Breast?
Since the stuffed chicken is rich and flavorful, I recommend pairing it with lighter sides:
Creamy Baked Lemon Herb Risotto complements the savory flavors perfectly.
Baby spinach with balsamic dressing offers a refreshing and healthy balance to the richness of the chicken.
You can also pair it with roasted veggies like asparagus or broccoli for a healthy and hearty meal.
Storage Instructions
Keep Fresh: Store leftover stuffed chicken breasts in an airtight container in the fridge. They will stay fresh for up to 3 days.
Freeze: Let the chicken cool completely, then wrap each stuffed chicken breast individually in plastic wrap and place them in a freezer bag. These can be frozen for up to 3 months.
Reheat: To reheat, place the chicken in the oven at 350°F (175°C) for 15-20 minutes, or until thoroughly heated.
