1 package dry onion soup mix
1 cup panko bread crumbs
4 skinless, boneless chicken breast halves
1/2 cup mayonnaise
Preheat an oven to 425 degrees F.
Combine the soup mix and panko in a mixing bowl; set aside.
Line a baking sheet with foil.
Coat the chicken breasts all over with mayonnaise, then press into the panko mixture.
Place the chicken on the baking sheet.
Cook the chicken until no longer pink in the center and the juices run clear, about 25 minutes.
