Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Using a sharp knife, carefully slice 8 oz boneless skinless chicken breast horizontally to create a pocket without cutting all the way through.
  2. Step 2: Heat 1 tbsp olive oil in a skillet over medium heat. Add 1 minced garlic clove and 1 cup chopped fresh spinach, sautéing for 2-3 minutes until wilted and fragrant. Remove from heat.
  3. Step 3: In a small bowl, mix sautéed spinach, 2 tbsp softened cream cheese, 1/2 cup shredded mozzarella cheese, 1/2 tsp salt, 1/4 tsp black pepper, and 1/2 tsp dried Italian herbs until well combined.
  4. Step 4: Stuff the chicken breast pocket evenly with the spinach mixture, securing with toothpicks if needed. Place on a baking dish and bake for 25-30 minutes until chicken is cooked through and juices run clear.
