Creating your Irresistibly Juicy Spinach Stuffed Chicken Breast is simple if you follow these straightforward steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Spinach Mixture: In a bowl, combine the chopped spinach, cream cheese, mozzarella, Parmesan, garlic, Italian seasoning, salt, and pepper. Mix until well incorporated.
3. Prepare the Chicken: Using a sharp knife, carefully slice a pocket into each chicken breast. Ensure not to cut all the way through.
4. Stuff the Chicken: Generously fill each chicken breast pocket with the spinach mixture. Use toothpicks to secure if necessary.
5. Sear the Chicken: In a large oven-safe skillet, heat olive oil over medium-high heat. Add the stuffed chicken breasts and sear for about 3-4 minutes on each side until golden brown.
6. Bake the Chicken: Transfer the skillet to the preheated oven. Bake for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F (75°C).
7. Rest and Serve: Remove from the oven and let the chicken rest for 5 minutes before slicing. This helps retain the juices.
8. Garnish: Optionally, sprinkle fresh parsley on top for a pop of color and added freshness.

With these steps, you’ll effortlessly create a dish that is both delicious and visually appealing!
