Place chicken strips in a bowl and cover with buttermilk. Refrigerate for 20–30 minutes.
Preheat oven to 400°F. Cut butter into pieces and place in a 9x13-inch baking dish. Put the dish in the oven until the butter melts. Swirl to coat the bottom.
In a bowl or Ziploc bag, mix flour, salt, seasoned salt, pepper, and paprika.
Remove chicken from buttermilk, letting excess drip off. Coat each piece in the flour mixture.
Arrange coated chicken pieces in the buttered baking dish.
Bake for 20 minutes, flip, and bake for another 20 minutes or until chicken reaches 170°F internally.
Remove from oven and let rest 5 minutes before serving.
