Start by softening the cream cheese so it mixes easily. In a large bowl, combine spinach, chopped artichokes, cream cheese, mozzarella, parmesan, sour cream, garlic, salt, and black pepper. Stir everything until smooth and evenly combined.
The filling should look creamy and thick. If it feels too loose, add a little extra parmesan cheese. I like chilling the filling for a few minutes because it becomes easier to stuff into the chicken.
Place each chicken breast on a cutting board. Using a sharp knife, carefully cut a deep pocket into the thickest side without slicing all the way through.
Try to make the pocket large enough for plenty of filling. I usually leave about half an inch around the edges so the stuffing stays inside while cooking.
Sprinkle both sides of the chicken breasts with salt and black pepper. This simple seasoning helps flavor the chicken itself and balances the creamy filling.
You can also add paprika, garlic powder, or Italian seasoning for extra flavor. I sometimes use smoked paprika because it adds a subtle smoky taste.
Spoon the spinach artichoke mixture into each chicken pocket. Avoid overfilling because the filling expands slightly during cooking.
Secure the openings with toothpicks if needed. This helps keep most of the cheesy filling inside while the chicken cooks in the skillet and oven.
Heat olive oil in an oven-safe skillet over medium heat. Once the pan is hot, place the stuffed chicken breasts presentation-side down.
Cook for about 5 minutes until golden brown. Flip carefully and cook the other side for another 3 minutes to create a flavorful crust.
Transfer the skillet to a preheated 375°F oven. Bake the chicken for 10 to 15 minutes or until the internal temperature reaches 165°F.
The filling should be hot and bubbly when finished. Let the chicken rest for about 5 minutes before serving so the juices stay inside.
Remove the toothpicks carefully before serving. Sprinkle chopped parsley over the top for freshness and color.
I love serving this chicken straight from the skillet because it looks rustic and inviting. The melted cheese inside makes every slice look incredible.
