Soak chicken breasts in milk for at least 30 minutes.
Preheat oven to 400 degrees. In a 9x13 baking dish, slice the butter into about 8-10 pieces and place around dish. Melt in oven while other steps are completed.
In a large bowl, place flour, season all, pepper, and paprika and mix with a wooden spoon. Take each piece of chicken and shake off excess milk, and dip into flour mixture. Flip it until it's covered in the mixture. Place each piece of chicken in prepared baking dish, making sure not to overlap pieces.
Bake for about 20 minutes, then flip each piece. Bake for another 20 minutes, or until chicken is no longer pink. Cut into a few pieces to ensure they are cooked thoroughly, and the juices run clear - internal temperature should be 165 degrees. If any side of the chicken is soggy, broil for 30 seconds to 1 minute (watch carefully).
