Langostino
Langostino is the meat from a small crustacean (genus Munida and related squat lobsters) that lives on the ocean floor off the coasts of Chile and South America. Despite the name meaning 'little lobster' in Spanish, langostino is not a baby lobster or a type of shrimp; it's its own species, distantly related to both. The tail meat is what's sold, usually already cooked and frozen, and it has a texture between shrimp and lobster with a sweeter, more delicate flavor than either.
Varieties
What's sold as 'langostino' in the US almost always comes from squat lobster species (Munida gregaria and related types) caught off Chile, not the spiny lobster or Norway lobster (which is actually where the name 'langoustine,' a different word, comes from). Langoustine, with the extra 'u,' is a separate creature entirely, closer to a small clawed lobster, and the two names get confused constantly on menus.
Buying tips
Look for it in the freezer section, usually labeled 'langostino tail meat' or sold under brand names as a lobster substitute. Check the bag for excessive ice crystals, a sign of thawing and refreezing. Some products blend langostino with lobster meat, so read the ingredient list if you want the real thing.
Substitutes
Cooked lobster tail meat, chopped — 1:1
Closest flavor match and the classic swap in dishes like langostino rolls, though it costs considerably more.
Large shrimp or prawns, cooked and chopped — 1:1
Firmer texture and slightly less sweet, but widely available and much cheaper.
Bay scallops — 1:1
Different flavor profile but a similar small, tender bite size for salads and pasta.
Crab meat, lump or claw — 1:1
Sweeter and more delicate than shrimp, a reasonable stand-in for langostino salad or cakes.
Storage
Langostino is almost always sold pre-cooked and frozen. Keep it frozen at 0°F (-18°C) or below until ready to use, up to about 9 months. Once thawed, store in the refrigerator and use within 1-2 days; do not refreeze.
How to use
Because it's pre-cooked, langostino only needs to be warmed through, not cooked from raw. Fold into pasta with garlic and butter, toss into salads, pile onto a roll with mayonnaise for a langostino roll, or fold into dips and crab-cake-style patties. Add it near the end of cooking, just long enough to heat, since extended cooking makes the small tails tough.
What it pairs with
Pairs well with butter, garlic, lemon, tarragon, and white wine, the same flavors used with lobster and scallops. Also works with mild cheeses in baked pasta dishes and with avocado in cold salads.
Nutrition
Langostino is low in fat and calories with a high protein content, similar to shrimp and lobster. A 3-ounce serving provides roughly 90-100 calories and around 18 grams of protein, along with some cholesterol typical of shellfish.
FAQ
Is langostino a shrimp or a lobster?
Neither. It's a squat lobster, a crustacean more closely related to hermit crabs than to true lobsters or shrimp, though its texture and flavor sit somewhere between the two.
Why is langostino always sold cooked?
Langostino spoils quickly after being caught, so it's typically boiled and frozen on fishing vessels or shortly after landing, which is also why most recipes only need to reheat it.
Can langostino be used raw?
Generally no. Nearly all commercially available langostino has already been cooked; look specifically for 'raw' or 'sashimi-grade' labeling if a recipe calls for cooking it from raw, which is uncommon.
Is langostino the same as langoustine?
No, despite the similar name. Langoustine (also called Norway lobster or scampi) is a small clawed lobster relative from European and North Atlantic waters, while langostino is a squat lobster from the Pacific coast of South America.
