Instructions

  1. Step 1: Preheat oven to 375°F. Using a sharp knife, cut a horizontal pocket into each of 2 boneless skinless chicken breasts, being careful not to slice all the way through.
  2. Step 2: In a bowl, combine 1 cup chopped fresh spinach, 3 oz softened cream cheese, 1/2 cup shredded mozzarella cheese, 1/4 tsp salt, and 1/4 tsp black pepper. Mix well.
  3. Step 3: Stuff each chicken breast pocket evenly with the spinach and cheese mixture, securing with toothpicks if needed. Season the outside of the breasts with remaining 3/4 tsp salt and 1/4 tsp black pepper.
  4. Step 4: Heat 2 tbsp olive oil in an oven-safe skillet over medium-high heat. Sear the chicken breasts for 3-4 minutes per side until golden brown.
  5. Step 5: Mix 3 tbsp softened unsalted butter, 1 tbsp finely chopped fresh parsley, and 1 minced garlic clove. Dollop the herb butter evenly over the seared chicken breasts.
  6. Step 6: Transfer the skillet to the preheated oven and bake for 15-18 minutes until the chicken is cooked through and internal temperature reaches 165°F.
  7. Step 7: Let rest for 5 minutes before serving, spooning any melted herb butter from the pan over the chicken.
