Set your oven to 350°F (175°C) and let it heat up.
02 -
Lay a chicken breast flat on your board. With a sharp knife, cut into the thinner side of the breast. Slice carefully across, but leave the far end uncut to form a pocket for stuffing.
03 -
Press the thawed spinach between paper towels (or use a cheese cloth) to remove all the extra water. In a bowl, mix the spinach, cream cheese, shredded Mozzarella, chopped artichoke hearts, minced garlic, oregano, ¾ teaspoon salt, and ¼ teaspoon pepper until combined.
04 -
Scoop about ⅓ to ½ cup of the spinach mix into each pocket you cut into the chicken breasts earlier. Sprinkle the outside of the chicken with the rest of the salt (½ teaspoon) and pepper (¼ teaspoon).
05 -
Pour oil in a big oven-safe skillet and warm it up over medium heat. Once the oil is hot, add the stuffed chicken breasts so they sit in a single layer. Let them brown on one side for 4-5 minutes, then carefully turn them over.
06 -
Place the skillet in the hot oven and cook for 22-24 minutes. The chicken is done when the middle reaches 165°F (74°C).
07 -
Sprinkle chopped parsley over the chicken before serving, if you'd like. Serve while it's still warm.
