Start by preheating your oven to 375°F (190°C). Make sure the rack is positioned in the center of the oven for even cooking.

In a medium bowl, combine the chopped roasted red peppers, chopped fresh spinach, shredded mozzarella cheese, garlic powder, paprika, and a pinch of salt and pepper. Mix everything together until well combined.

Place each chicken breast on a cutting board and, using a sharp knife, carefully slice horizontally into the side of the chicken breast to create a pocket. Be careful not to cut all the way through - you want to create a pocket that will hold the filling.
04 -
Divide the filling mixture evenly between the four chicken breasts, stuffing each pocket generously. You can secure the openings with toothpicks if needed to keep the filling from spilling out during cooking.

Heat the olive oil in a large oven-safe skillet over medium heat. Once hot, add the stuffed chicken breasts and sear for 3-4 minutes on each side until golden brown. This step helps seal in the juices and gives the chicken a beautiful color.

Transfer the skillet with the seared chicken directly to the preheated oven. Bake for 25-30 minutes, or until the chicken is cooked through and the internal temperature reaches 165°F (75°C) when checked with a meat thermometer.
07 -
Remove the skillet from the oven (remember to use oven mitts as the handle will be hot!). Let the chicken rest for 5 minutes before slicing. This allows the juices to redistribute throughout the meat, resulting in more tender chicken. Remove any toothpicks before serving.
