Substitutes for Catfish with ratios

  1. 2Basa, swai or pangasius

    Close match

    Use the same amount by weight

    Farmed Southeast Asian catfish relatives, sold frozen as boneless fillets.

    What changes
    Best for
    fried fish, baked fillets, curries and stews, fish sandwiches, any catfish recipe

    Genuinely the closest thing on a shelf, because these are catfish in the broad sense, farmed the same way and sold for the same money. The fillets are thinner than American channel catfish and a little softer and slightly oilier, so they stay moist when baked but need a firm hand when frying. They are also blander, without much of the sweetness or earthiness catfish carries, so season a touch more heavily. Press them very dry after thawing.

  2. 3Cod, haddock or pollock

    Taste and texture differ

    Use the same amount by weight

    Lean cod-family ocean fish, sold fresh or frozen almost everywhere.

    What changes
    Best for
    fried fish, baked fish, chowder, fish sandwiches, fish tacos, blackened fillets

    Very good fish and a clear flavor change: cleaner, sweeter and unmistakably of the sea, with none of catfish's freshwater earthiness. The flake is much larger and looser, which looks handsome on a plate but makes them fragile, so a piece of battered cod is more likely to break in the fryer or fall apart when lifted out. Chill the fillet, blot it dry and dredge firmly in flour before the cornmeal or batter. In a stew they will flake apart much sooner than catfish, so add them in the last five to eight minutes.

  3. 4Grouper, redfish, drum or striped bass

    Different taste

    Use the same amount by weight

    Firm-fleshed fish that keep their shape in liquid and on a grill.

    What changes
    Best for
    etouffee, court bouillon, gumbo, grilled fillets, blackened fish, fried fish sandwiches

    The right choice whenever the fish has to survive being simmered or turned, which is where catfish's density is doing the real work. All four hold in cubes without collapsing and take blackening seasoning beautifully, and redfish and drum are the traditional Louisiana choices for exactly these dishes. They cost more than catfish, sometimes a great deal more in the case of grouper, and they are cleaner and sweeter tasting, so a court bouillon made with them is brighter and less earthy.

  4. 5Freshwater trout, perch or walleye

    Different texture

    Use the same amount by weight, with a shorter cook

    Other freshwater fish, matched to catfish on flavor rather than on price.

    What changes
    Best for
    pan-fried fish, cornmeal-crusted fillets, fish fry, baked fillets, shore lunches

    Choose these if you want catfish's specific freshwater character and cannot get catfish. All three share that slightly sweet, faintly earthy, non-oceanic taste, and perch and walleye in particular are classic fish-fry material. They are considerably more delicate and thinner, so they cook in three or four minutes rather than six or seven and will fall apart if you fuss with them. Trout is oilier and richer than catfish, which makes it excellent pan-fried in butter and less suited to a deep fry.

  5. 6Alligator, shrimp or crawfish tails, for Louisiana dishes

    Taste and texture differ

    Use the same amount by weight, added near the end

    Non-fish proteins that fit the same regional recipes.

    What changes
    Best for
    etouffee, gumbo, court bouillon, fried appetizers, sauce piquante

    Worth knowing because in Louisiana cooking the sauce is the dish and the protein is interchangeable. Shrimp and crawfish belong in every one of these recipes already, are sweeter than catfish, and cook in two or three minutes, so add them at the very end. Cubed alligator tail gives you a firm springy bite and almost no flavor of its own, so it leans entirely on the seasoning. None of these will work in a cornmeal-fried fish plate where the point is a fillet, although fried shrimp is a fine substitute plate in its own right.

What is Catfish?

Catfish is a freshwater fish sold mostly as thick boneless fillets from US farms, denser, firmer and a little sweeter and richer than most white fish, with a mild earthy note that Southern cooking leans on and that some people would rather avoid.

Cooking tips

  • Soak the fillets in milk or buttermilk for thirty to sixty minutes before cooking, then drain and pat dry. This is standard Southern practice and it does two things: it softens the muddy or earthy note, which is far stronger in wild river catfish than in farmed, and it gives the cornmeal something to stick to. If you substitute trout, perch or alligator, keep the soak for the same reason.
  • Cornmeal, not flour, is the Southern coating, and it needs a dry fillet to grip. Mix cornmeal with a little flour, salt, cayenne and black pepper, press it on firmly and fry at 350F to 360F, allowing five to seven minutes for a thick catfish fillet. A wetter, softer substitute such as cod or pollock will shed the coating unless you blot it hard and dredge it in plain flour first.
  • Catfish is thicker than most cheap white fish, which changes every timing in a recipe. A one-inch farmed fillet takes six or seven minutes in the fryer and twelve to fifteen minutes at 400F in the oven, while a tilapia fillet at half that thickness is done in half the time. When you substitute, look at the fillet rather than at the clock.
  • If you are using wild or river catfish, trim the dark reddish strip along the lateral line and any yellow fat. That is where the muddy flavor concentrates, and removing it makes a much bigger difference than any soak. Farmed catfish is bred and fed to be mild and usually needs no trimming at all.
  • In a stew, catfish holds its shape longer than most white fish, so if you switch to cod, haddock or tilapia, add them in the last five to eight minutes rather than simmering them for twenty. If you want cubes of fish that stay intact through a long etouffee, use grouper, redfish or drum instead.

Frequently asked questions

What fish tastes closest to catfish?

Basa or swai, which are farmed relatives and the nearest match in texture and price, followed by freshwater trout, perch or walleye if it is the slightly sweet, faintly earthy freshwater character you are after. Tilapia is the easiest swap to buy and is close in role though blander and thinner. Ocean fish such as cod and haddock are excellent but taste clearly different, cleaner and more marine.

Does catfish taste muddy, and how do I avoid that?

Farmed American catfish is bred and fed specifically to be mild and rarely tastes muddy at all. Wild river catfish can, because the flavor concentrates in the fat and in the dark strip along the lateral line, so trim both away. A thirty to sixty minute soak in milk or buttermilk mellows it further. If you simply do not like the flavor, tilapia, basa or cod are the substitutes to choose, since all three are milder.

Can I use tilapia to make fried catfish?

Yes, and it is a common substitution. Use the same buttermilk soak and the same seasoned cornmeal, but blot the fillets very dry first because tilapia holds more water, and cut the frying time to about three or four minutes since the fillets are much thinner. The result is lighter and flakier, with a smaller piece on the plate and a less dense bite, and it will taste more of the cornmeal and seasoning than of the fish.

Can I just leave the catfish out of an etouffee?

The dish needs a protein, but it does not need this one. Shrimp and crawfish are the classic choices for etouffee and are arguably more traditional than catfish, and either can be stirred in during the last two or three minutes. Chicken thigh also works. What you should not do is simply omit the protein and serve the sauce over rice on its own, since the roux and the trinity need something to carry.

Is frozen catfish as good as fresh, and how should I thaw it?

Most catfish sold outside the South is frozen and it holds up well, since the flesh is dense. Thaw it overnight in the fridge on a rack so the melt water drains off, then blot both sides firmly and give it the milk soak if you are frying. Do not thaw it in warm water and do not fry it while still damp, or the cornmeal will slide off in the oil.
