Heat 2-3 inches of oil in a Dutch oven to 350°F.
In a shallow dish whisk together buttermilk, egg and hot sauce. (adjust amount of hot sauce to taste)
In a separate shallow dish whisk together cornmeal, flour, seasoned salt, lemon pepper or black pepper, garlic, onion powder and paprika.
Add oysters to buttermilk mixture, let soak for 5-10 minutes.
Remove the oysters from the buttermilk allowing the excess to drip off. Dredge in the dry ingredients coating on all sides.
Drop oysters in hot oil, cooking in batches for around 2 minutes or until golden brown and crispy, turning as needed for even browning.
Remove from the oil using a stainless steel spider or slotted spoon to a paper towel-lined plate, platter or sheet pan to drain. Sprinkle lightly with additional seasoned salt.
Serve immediately with a remoulade, tarter sauce or cocktail sauce for dipping, garnished with lemon wedges.
