Creating spinach stuffed chicken breasts is a straightforward process. Follow these simple steps for success:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C).
2. Prepare the Filling: In a large bowl, combine the chopped spinach, ricotta cheese, mozzarella cheese, and minced garlic. Season with salt and pepper to taste. Mix well.
3. Prepare the Chicken: Using a sharp knife, carefully slice a pocket into each chicken breast. The pocket should not cut all the way through.
4. Stuff the Chicken: Fill each chicken breast pocket with the spinach filling. Be generous, but be sure to not overfill.
5. Secure the Filling: Use toothpicks to secure the openings of the stuffed chicken breasts to keep the filling from spilling out during cooking.
6. Sear the Chicken: In an oven-safe skillet, heat a drizzle of olive oil over medium-high heat. Sear the chicken breasts for about 3-4 minutes on each side until golden brown.
7. Bake: Once the chicken is nicely browned, transfer the skillet to the preheated oven. Bake for 25-30 minutes or until the internal temperature reaches 165°F (74°C).
8. Rest: Remove the chicken from the oven and let it rest for about 5 minutes to allow the juices to redistribute.
9. Serve: Slice each chicken breast and enjoy the beautiful, cheesy filling!
