Ingredients

4 boneless, skinless chicken breasts (approx. 6–8 oz / 170–225g each)

4 oz (115g) cream cheese, softened to room temperature

1 cup (100g) shredded mozzarella cheese (or provolone)

2 cups (60g) fresh baby spinach, chopped (or 1/2 cup frozen spinach, thawed and squeezed dry)

2 cloves garlic, minced

1 tbsp olive oil (for cooking)

1 tsp garlic powder

1 tsp onion powder

1 tsp Italian seasoning

1 tsp sea salt

1/2 tsp freshly ground black pepper

Instructions

🟢Prepare the Filling:

    In a medium mixing bowl, combine the softened cream cheese, shredded mozzarella, chopped spinach, minced garlic, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper. Mix until smooth and well integrated.

      🟢Prep & Cut the Chicken:

        Pat the chicken breasts dry with paper towels. Place your hand flat on top of a chicken breast and use a sharp knife to cut a deep horizontal pocket into the thick side, being careful not to cut all the way through to the other edge.

          🟢Season the Outside:

            In a small dish, mix the garlic powder, onion powder, Italian seasoning, remaining 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Rub olive oil lightly over the outside of each chicken breast, then coat evenly with the seasoning mix.

              🟢Stuff the Chicken:

                Spoon 1/4 of the spinach-cheese mixture into the pocket of each chicken breast. Secure the open edges with toothpicks (2–3 per breast) to keep the filling enclosed.

                  🟢Sear & Bake:

                    Preheat your oven to 375°F (190°C).

                      Heat 1 tablespoon of olive oil in an oven-safe skillet (like cast iron) over medium-high heat. Add the stuffed chicken breasts and sear for 3 to 4 minutes per side until golden brown.

                        🟢Finish Cooking & Rest:

                          Transfer the skillet to the preheated oven and bake for 12 to 15 minutes, or until the internal temperature reaches 165°F (74°C) at the thickest part of the meat. Remove toothpicks, let rest for 5 minutes, and serve warm!

                            Notes

                            • Cheese Swap: Replace mozzarella with sharp cheddar, Swiss, or crumbled feta for a bolder, tangier flavor profile.
                            • Greens/Filling Add-ins: Swap fresh spinach with chopped sun-dried tomatoes, roasted red peppers, or artichoke hearts for a Mediterranean variation.
                            • Cooking Method (Air Fryer Alternative): Instead of oven baking, place stuffed chicken breasts in a preheated air fryer at 360°F (180°C) for 16–18 minutes, flipping halfway through.
