Soak catfish in milk for approximately 1 hour, in the refrigerator. In a bowl, mix together white and yellow cornmeal. Spice up the cornmeal with salt, red and black pepper, granulated garlic, thyme, and Cajun seasoning, to taste.
Preheat oven to 400 degrees F.
Take the fish out of the milk and shake off the excess milk. Dip the fish fillets in the spiced cornmeal mixture. Put the fillets on a buttered cookie sheet and drizzle butter over the fish. Or you can use a butter spray. Bake fish in oven for approximately 10 minutes. Time may vary depending on the thickness of fillet. Fish should get a nice crusty, golden color. Serve with tartar sauce.
