Instructions

  1. Step 1: Preheat oven to 375°F. Slice 4 boneless skinless chicken breasts horizontally to create a pocket, being careful not to cut all the way through.

  5. Step 5: Sear the chicken breasts for 3 minutes on each side until golden brown.
  6. Step 6: Melt 3 tbsp unsalted butter in the skillet, add 3 minced garlic cloves, and cook for 1 minute until fragrant.
  7. Step 7: Transfer the skillet to the preheated oven and bake for 15-18 minutes until chicken is cooked through (internal temperature 165°F).
