Blend all dry ingredients from the panko crumbs to the lemon zest in one medium sized bowl.
In a second medium sized bowl, beat the eggs.
Heat the butter and oil to hot on the stove OR pre-heat your oven to 400 degrees.
Begin dipping the fish filets in the beaten eggs.
Dip egg-washed fish filets into the panko-herb breading.
Dip AGAIN into the eggs.
Dip AGAIN into the breading.
Place the breaded fish filets into the hot butter-oil, cover with a lid.
Fry for about 3 to 4 minutes on each side, depending on the heat of the oil.
Keep your eyes on the fish so that they cook until a nice golden brown color on each side.
For the dipping sauce, melt the butter and add lemon juice and garlic.
If you bake the fish, place them in a baking pan that has been sprayed with cooking oil.
Bake until golden brown.
Garnish with lemon slices or wedges.
Serve with lemon-garlic butter and/or tartar sauce.
