Step 1: Prepare the Chicken Breasts

• Preheat your oven to 375°F (190°C).

• Place the chicken breasts on a cutting board and pat them dry with paper towels.

• Using a sharp knife, carefully cut a horizontal slit into the thickest part of each chicken breast to create a pocket for the filling. Be careful not to cut all the way through.

Step 2: Season the Chicken

• In a small bowl, mix salt, black pepper, garlic powder, and paprika.

• Rub the seasoning mixture evenly over both sides of the chicken breasts.

Step 3: Make the Spinach Filling

• In a mixing bowl, combine chopped spinach, cream cheese, mozzarella, Parmesan, minced garlic, Italian seasoning, and red pepper flakes. Mix until well combined.

Step 4: Stuff the Chicken Breasts

• Spoon the spinach filling into the pockets of each chicken breast. Use toothpicks or kitchen twine to secure the openings.

Step 5: Cook the Chicken

• Heat olive oil in an oven-safe skillet over medium-high heat.

• Sear the chicken breasts for 2-3 minutes on each side until golden brown.

• Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).

Optional Step:

• During the last 5 minutes of baking, top the chicken with marinara sauce and extra mozzarella cheese for a cheesy finish.
