In a separate bowl, combine the Panko breadcrumbs, grated parmesan, melted butter, and salt.
Now dredge each chicken breast into the mayonnaise mixture.
Then transfer it to the bowl of breadcrumbs. Evenly coat each chicken breast with the bread crumbs.
Place the coated chicken breast onto a baking sheet lined with parchment paper.
Bake at 375 for 35-40 minutes. Use an instant-read thermometer to check the thicket part of the chicken. It should read at least 165°F. This is the best way to ensure that the chicken is fully cooked, perfectly juicy, and tender.
