Preheat the oven to 375 degrees F (190 degrees C).

Mix turkey, bread crumbs, Parmesan cheese, egg, parsley, and salt together in a large bowl. Form meat mixture with wet hands into balls about 1 1/2 inches in diameter without handling or packing too hard.

Bake in the preheated oven until browned, about 20 minutes. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).
