Divide each chicken breast into two or three strips depending on size. Place the pieces in a bowl and submerge them in milk. Allow the chicken to marinate for at least 30 minutes or, for deeper flavor, overnight in the refrigerator.
Preheat the oven to 375°F.
In a separate bowl, blend the Greek yogurt with half of the grated parmesan, salt, garlic powder, onion powder, paprika, and freshly ground black pepper to taste.
Arrange the marinated chicken in a 9×13-inch baking dish and season lightly with additional salt if desired. Evenly coat each piece with the yogurt mixture, then scatter the remaining parmesan over the top.
Finish with a light dusting of paprika. Bake for 40 minutes, then briefly broil until the top develops a golden hue.
