Langostinos in garlic butter sauce

For this recipe, we are making a quick garlic butter sauce. Not simply adding garlic to melted butter, which is perfectly fine, but not exactly a sauce.

First, we will make a roux by combining melted butter with a bit of flour. Then fresh lemon juice and a bit of stock are added to make our lemony garlic butter sauce.

Fear not, this silky garlic butter sauce is super simple and takes only a few minutes to come together. The langostinos are already cooked, so all you have to do is add them to the sauce to heat through and that’s it! This recipe is fast, easy and incredibly delicious.

We love langostinos, so when I spot them at Costco or Trader Joes, I grab them. Luckily, we are both seafood lovers in this house. Because they are sold frozen, it’s easy to grab a couple of pounds and stash them in the freezer until I’m ready to use them.

How to cook langostino

Langostinos are sold already peeled and cooked, then frozen. That is the best part of making a langostino recipe. To add them to your recipe all you have to do to prepare them is thaw and drain them well.

If you are unfamiliar with langostinos, the flavor is similar to lobster, but they look a bit like crayfish. This delicate crustacean is super versatile and incredibly tasty. You can substitute langostinos in recipes that call for lobster or shrimp.

Langostino is a term that can be used for a few varieties of crustaceans, depending where you are in the world. It can refer to a species of shrimp or to a certain species of lobster, although they are technically related to a crab. A langoustine is in the lobster family and is different from a langostino.
