In a large Dutch oven or cast-iron pan, heat about 3” of vegetable oil to medium-high heat, until oil reaches 350 degrees F.
Prepare three separate bowls: one with all-purpose flour, one with buttermilk, and one with seasoned flour. Dip chicken wings in all-purpose flour, then in buttermilk, and then in seasoned flour.
Fry wings in small batches until golden brown and warmed throughout, about 5 to 7 minutes.
Once chicken wings are done, place on wire rack and lightly season with kosher salt.
In a large bowl, place cooked wings, garlic butter, Parmesan cheese and Italian parsley; toss lightly until well coated.
Finish plate by sprinkling more Parmesan on top wings.
