Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Using a sharp knife, carefully cut a deep pocket into each of the 4 chicken breasts without cutting all the way through.
  2. Step 2: Heat 2 tbsp olive oil in a skillet over medium heat. Add 2 minced garlic cloves and 2 cups chopped fresh spinach, cooking for 3-4 minutes until spinach wilts and garlic is fragrant. Remove from heat.
  3. Step 3: In a bowl, mix the sautéed spinach and garlic with 4 oz softened cream cheese and 1 cup shredded mozzarella cheese until well combined.
  4. Step 4: Stuff each chicken breast pocket evenly with the spinach-cheese mixture. Secure with toothpicks if needed. Season the outside of each breast with 1 tsp salt, 1/2 tsp black pepper, and 1 tsp dried Italian seasoning.
  5. Step 5: Place chicken breasts in a baking dish and bake uncovered for 25-30 minutes until chicken is cooked through and juices run clear. Let rest 5 minutes before serving.
