Cooking frozen clams is just as simple as fresh. First, you'll need to thaw them. So, set them in the fridge overnight, or in the morning. They won't take long to thaw, just a few hours, being that they're pretty thin. There are tons of fantastic clam recipes on our page, check them out and get to your clam dinner! Or appetizer! So, let's ditch the "what can I do with frozen razor clams" and get to making this clam spaghetti with wine sauce. Or try clam jalapeno poppers, clam dip, and of course, Mediterranean clam ceviche is a fan favorite!
