Caprese Chicken Sandwich with Basil Pesto Mayo

Lightly seasoned chicken breast is topped with mozzarella cheese, juicy ripe tomatoes, and garden fresh basil. This Caprese Chicken Sandwich is served on a buttery brioche roll and smothered in basil pesto mayo.

  • Total Time: 25 minutes
  • Yield: 4 servings 1x


  • 1 pound thin-sliced boneless skinless chicken breast (at least 4 slices)
  • Salt & pepper
  • 1/4 cup mayonnaise
  • 1/4 cup basil pesto
  • 4 brioche buns
  • 1 ounce fresh basil leaves
  • 8 ounces fresh mozzarella cheese - sliced
  • 2 medium-sized tomatoes - sliced


  1. Season both sides of the chicken breast slices with salt and pepper.  Cook your chicken breast on the stovetop in an oiled pan over medium heat, for about 4 minutes per side.  Cook the chicken until it has reached an internal temperature of at least 165°F.  Remove from heat and set aside.   
  2. Combine the 1/4 cup of mayonnaise and the 1/4 cup of basil pesto in a small mixing bowl.  Mix together until fully combined.
  3. Assemble your Caprese Chicken Sandwiches.  Open the brioche buns. Evenly spread the pesto mayo on the inside of the bun.  Place the cooked chicken breast on the bottom half of the bun.  Top the chicken breast with sliced mozzarella, tomato slices and fresh basil leaves and top with the remaining half of the brioche bun. Serve and enjoy!


  • Grilling instructions - Grill chicken breast on a hot grill that is heated to about 425°F.  Cook for about 5 minutes per side or until the internal temperature has reached at least 165°F.
  • Optional step - Toast the inside of the brioche buns in melted butter in a frying pan on the stove.  Toasting the inside of the buns makes them golden brown and crispy.  Melt about 1 tablespoon of butter in a large frying pan.  Place the brioche buns into the frying pan cut side down.  Toast for about 5 minutes or until golden brown.
