Oysters substitute

Substitutes for Oysters with ratios

1. 2Bay scallops

   Different taste

   Use the same amount by count or weight

   Add them off the heat at the end of a stew, or nestle them into a gratin for the final few minutes.

   What changes

   Never let them boil.

   Best for

   oyster stew, gratins, Rockefeller-style baked dishes, chowder

   The closest textural match on this list, because a bay scallop is soft, plump and slightly custardy in the way a cooked oyster is. The flavor gap is wide: scallops are sweet and clean where oysters are saline and mineral, so add a good pinch of salt and a teaspoon of clam juice per serving. Overcook them and they go squeaky.

2. 3Mussels

   Taste and texture differ

   Use the same amount by count

   Steam open, pull the meat out, and use it wherever the recipe wanted shucked oysters.

   What changes

   Keep the strained steaming liquor and use it as the oyster liquor.

   Best for

   Rockefeller-style baked dishes, stew, stuffing, pasta

   Mussels bring genuine brine, which is the thing most swaps miss, and their steaming liquor is a good proxy for oyster liquor. The meat is firmer, sweeter and chewier and holds its shape rather than melting into the dish, so a stuffing made with mussels has distinct little bites in it instead of soft folds.

3. 4Chopped clams, fresh or canned with juice

   Different texture

   Use the same amount by weight, plus the juice

   Stir in during the last minute of cooking.

   What changes

   Use the clam juice as the liquid the oyster liquor would have provided.

   Best for

   oyster stuffing, stew, fritters, chowder, dips

   Salinity and mineral character land nicely, and canned clams are available anywhere. What changes is bite and body: clams are chewy and springy rather than silky, and they do not soften into the surrounding dish, so the finished stuffing or stew feels more textured and less rich.

4. 5Smoked oysters from a tin

   Taste and texture differ

   Use 3 to 4 chopped smoked oysters for every 6 fresh oysters

   Chop and fold into a stuffing, dip or chowder at the end, with a little of the oil.

   What changes

   Use half what you think you need and taste.

   Best for

   stuffing, dips, chowder, spreads

   The only pantry item that will genuinely make a dish taste of oyster, which is why it is worth keeping a tin. The smoke is assertive and will take over a delicate cream stew, so use it in something robust, and count on it reading as smoky-savory depth rather than as fresh oyster.

5. 6Oyster mushrooms + kombu (shellfish-free)

   Different taste

   Use 6 oz torn mushrooms + a 3-inch strip of kombu for every 12 oysters

   Tear the mushrooms, brown them hard in butter or oil until the edges crisp, and simmer the kombu in the stock or cream for 10 minutes before building the dish.

   What changes

   Best for

   vegan stuffing, shellfish allergy versions, vegetarian chowder, baked gratins

   Silky, savory and satisfying, and browning the mushrooms hard is what makes it work. Say it plainly though: mushrooms are not briny, so the kombu is doing the sea work, and a pinch of kelp powder or a splash of soy sauce at the end helps. Shellfish allergy is serious, so do not swap in another bivalve, and do not use a broth that held shellfish.
