Ingredients Needed to Make Southern Fried Fish Fillets

You don’t need a long grocery list to make incredible fried fish. Here’s everything you’ll need, broken down by component:

The Fish

Fresh or fully thawed fish fillets (speckled trout or catfish) — the star of the show
Paper towels — for patting the fish dry before coating

The Egg Wash

Eggs — bind the breading to the fish and help create a thick, even coating
Milk — thins the egg wash for better coverage
Creole seasoning, to taste — the backbone of Southern flavor
Garlic powder, to taste — adds savory depth
Onion powder, to taste — rounds out the seasoning
Paprika, to taste — adds color and mild sweetness

The Breading

Zatarain’s Fish Fry — the gold standard Southern fish fry coating
Zatarain’s also offers a gluten-free fish fry — a great option for those with celiac disease or gluten sensitivity

For Frying

Vegetable oil or peanut oil — peanut oil has a higher smoke point and adds a subtle richness

How to Fry Fish Fillets Southern Style

This recipe moves fast once the oil is hot, so read through all the steps before you start. The whole process from prep to plate, takes under 30 minutes.

Step 1: Prep the Fish

If your fish was frozen, make sure it’s fully thawed before you start. Pat every fillet dry with paper towels, both sides. This is a step most people skip, but it makes a real difference. Excess moisture creates steam when the fish hits the hot oil, which leads to soggy, uneven breading instead of a crisp, golden crust.

Step 2: Make the Egg Wash

In a wide, shallow bowl, whisk together the eggs, milk, Creole seasoning, garlic powder, onion powder, and paprika. Season generously, this is where the flavor goes into the fish. The egg wash should taste well-seasoned on its own. Don’t be shy with the Creole seasoning; it’s doing the heavy lifting here.

Step 3: Coat the Fish

Add the fish fillets to the egg wash and turn each piece to coat thoroughly on both sides. Let them sit in the wash for a minute or two, this helps the coating adhere better and gives the seasonings time to penetrate the fish slightly.

Step 4: Bread the Fish

Pour Zatarain’s Fish Fry into a large zip-lock bag. Lift the fillets from the egg wash one at a time, letting excess drip off, and place them in the bag. Seal the bag and shake gently until each fillet is completely and evenly coated. The zip-lock method is cleaner than a plate and gives you a more even coat than dredging.

Step 5: Heat the Oil

Pour enough oil into a deep, heavy skillet (cast iron is ideal) to reach about ½ inch deep, roughly 3 to 4 cups for a standard 10–12 inch skillet. Heat the oil over medium-high heat until it reaches 350°F. Use a thermometer if you have one; the temperature matters more than people realize. Oil that’s too cool means greasy fish, and oil that’s too hot means burnt breading with a raw center.

Step 6: Fry the Fish

Working in batches to avoid crowding the pan, carefully lower the breaded fillets into the hot oil. Don’t stack or overlap the fish, crowding drops the oil temperature and leads to steaming instead of frying. Cook until the fish is golden brown on the bottom, then flip once. The fish is done when it floats to the top of the oil, the breading is deep golden brown all over, and the flesh flakes easily when tested with a fork. This typically takes 3–5 minutes per side depending on the thickness of the fillet.

Step 7: Drain

Remove the cooked fillets from the oil with a slotted spatula or spider strainer and place them on a wire rack set over a baking sheet, or on a plate lined with paper towels. A wire rack is preferred, it lets air circulate under the fish and keeps the crust crispier longer. Season lightly with a pinch of salt immediately while still hot.

Storing and Reheating

Fried fish is best eaten fresh and hot, that’s just the truth. The crust is at its peak crunch the moment it comes out of the oil, and nothing fully replicates that. That said, leftovers can still be delicious if handled correctly.

Store leftover fried fish in an airtight container in the refrigerator for up to 2 days. Do not leave fried fish at room temperature for more than 2 hours. To reheat, skip the microwave — it will steam the crust and make it soft and rubbery. Instead, reheat fillets in an air fryer at 375°F for 3–4 minutes, or in a 400°F oven on a wire rack for about 8–10 minutes, until the crust crisps back up and the fish is heated through. A hot skillet with just a touch of oil also works well for stovetop reheating.

Freezing is not recommended for already-fried fish — the breading tends to separate from the fillet and become mushy after thawing. If you want to prep ahead, you can freeze the raw, breaded fillets on a sheet pan, then transfer to a freezer bag. Fry directly from frozen, adding a few extra minutes to the cook time.
