This Stuffed Chicken Caprese Sandwich is our favorite summer grill recipe! Chicken breasts stuffed with fresh mozzarella, basil, and tomato, marinated in balsamic reduction, grilled, and made into a delicious chicken sandwich. AMAZING!
Print Recipe


  • 2 cups balsamic vinegar
  • 3 tablespoons honey
  • 4 large boneless skinless chicken breasts
  • salt pepper, and garlic powder to taste
  • 4 large slices tomato
  • 8 small slices fresh whole milk mozzarella
  • 8 large leaves fresh basil
  • 4 Cobblestone Bread Co.™ hamburger buns we used the Sesame Twist…yum!


  • In a small saucepan, heat the vinegar and honey over medium/high heat. Bring to a boil and then reduce to a simmer, stirring regularly. When it starts to thicken and has reduced by about half (approximately 10 minutes), remove from the heat and set aside.
  • Season each chicken breast with salt, pepper, and garlic powder to taste. Cut each breast lengthwise, but not all the way, forming a “pita” shape. This is where you will place the mozzarella, basil, and tomato later.
  • Place the chicken in two large ziplock bags and pour some of the balsamic reduction into each bag, reserving a small amount for garnish. Allow to marinate in the fridge for at least 30 minutes before grilling.
  • When ready to grill, spray your cooking grid with non-stick spray or brush with canola oil. Stuff each chicken with one slice tomato, 2 leaves basil, and 2 slices fresh mozzarella. Use a toothpick to seal the opening if desired, this will make flipping the chicken easier.
  • Grill the chicken over medium/high heat, approximately 450 degrees, for 5-7 minutes on each side or until chicken is cooked through. This will determine on the thickness of the chicken you picked. When the chicken is white throughout, it’s done!
  • Place chicken onto the bottom bun and drizzle with a bit more of the reserved balsamic reduction. Top with the top part of the bun.
  • Enjoy!
