Grouper substitute

Substitutes for Grouper with ratios

1. 2Halibut

   Different taste

   Use the same amount by weight

   Thick, dense, premium flatfish sold as steaks or thick portions.

   What changes

   Best for

   grilling, roasting and baking, pan-searing, poaching, special-occasion plates

   The most exact texture match on this list, with the same thick firm flake that makes grouper worth the money, and a similar or higher price. It is sweeter and cleaner tasting than grouper, and considerably less forgiving: halibut is very lean and turns dry and cottony within a minute or two past done, so pull it at 130F to 135F and rest it. Grouper, by comparison, stays moist over a wider window. Deep-frying halibut inside a thick batter is a waste of the fish.

2. 3Mahi mahi or swordfish

   Different taste

   Use the same amount by weight

   Firm warm-water fish sold in thick steaks that behave like meat on a grill.

   What changes

   Best for

   grilling, kebabs and skewers, blackened fish, fish tacos, searing in cast iron

   The right choice if the recipe puts the fish over fire, since both are firmer than grouper and will not break or stick. Mahi is milder and leaner with a large flake, so it is the closer of the two; swordfish is denser, meatier and slightly richer and reads almost like a pork chop in a taco. Both are lean and should come off at 135F to 140F. Neither has grouper's soft-flaking quality, so they are less suited to a chowder or a stew where you want the fish to break into moist petals.

3. 4Cod or haddock

   Taste and texture differ

   Use the same amount by weight

   Lean cod-family white fish, the most available and affordable option.

   What changes

   Best for

   fried grouper sandwiches, battered fish, baked fillets, chowder, fish tacos, blackened fish in a pan

   Excellent fish and the honest budget answer, with one real limitation. Cod and haddock are sweeter and cleaner tasting than grouper and their flake is just as large, but they are much softer and wetter, so a thick fillet can slump in a pan, break when you turn it, and fall through grill grates. Cut the pieces thick, blot them very dry, dredge them in flour before any batter, and choose frying or baking over grilling. In a chowder they will flake apart sooner than grouper, so add them in the last five to eight minutes.

4. 5Monkfish, amberjack, striped bass or hake

   Close match

   Use the same amount by weight

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

   What changes

   Best for

   stews and chowders, grilling, kebabs, blackened fillets, pan-searing, Caribbean brown stew fish

   The best value substitutes for grouper's structural job. Monkfish is the firmest fish here, dense and slightly sweet and often compared to lobster, and it holds cubes through a long simmer better than grouper does. Amberjack is steaky and often sold in the same Gulf markets. Striped bass is a shade softer but sears beautifully skin-on. Hake is the softest of the four and the closest in price to cod. All taste a little more of themselves than grouper does, which is generally welcome.

5. 6Catfish or tilapia

   Taste and texture differ

   Use the same amount by weight, with a shorter cook

   Cheap farmed fillets, useful for fried preparations only.

   What changes

   Best for

   fried fish sandwiches, cornmeal-crusted fish, fish tacos, breaded fillets

   Said plainly, this is the biggest step down on the list, and it is fine in exactly one context: a fried sandwich or a battered fillet, where the coating and the tartar sauce set the tone. Catfish is much the better of the two here because it is denser and firmer; tilapia is thin, soft and bland. Both cook in three or four minutes rather than eight to twelve, and neither will survive a grill, a stew or a plated dish where the fish is meant to be admired. Season them more heavily than the recipe says.
