Beat the egg and pour it onto a large plate, big enough to coat the fish fillets.

Mix all the dry ingredients together and spread them out on a separate plate.

Heat a skillet over medium heat until hot.

Pat the fish fillets dry with a paper towel, dip them in the beaten egg, then coat them in the prepared flour mixture, and place them in the hot oil to fry.

Let the fillets cook thoroughly on one side before flipping them. Flip when the coating starts to turn golden brown.

Once cooked on both sides, place the fillets on a thick paper towel to drain excess oil.
