Buy mussels the day you plan to cook them, they're alive after all and don't last long. At the store, look for tightly closed shells or shells that snap shut when tapped; any that stay open are dead and should be skipped. Farm-raised PEI mussels are the easiest to find and the cleanest. They're rope-grown, so they have less grit and smaller beards. Store them in the fridge in a bowl covered with a damp paper towel (never sealed in a bag or submerged in water as they'll suffocate). Plan to cook within 24 hours of buying. Frozen mussels are great and even easier because you don't usually have to clean or sort. Good option for people who don't live near good seafood.
Mussels are one of the fastest proteins you'll ever cook, 3 to 5 minutes from pot to plate. They're a great weeknight dinner because they're fast and the cooking liquid is almost like a built-in sauce. The actual cooking is almost impossible to mess up if you follow some simple guidelines. Where people go wrong is what they do before they turn on the heat: skipping the sorting (toss any that won't close when you tap them) or not debearding properly. Get the prep right and the rest takes care of itself. Below you'll find times for steaming, roasting, and grilling.
Mussels don't have a target internal temperature; the shell opening is your doneness indicator. When the shells pop open, the meat inside has reached a safe temperature from the steam. The real food safety work happens before and after cooking. Before: tap any open mussels on the counter. If they close, they're alive and safe. If they stay open, they're dead — throw them out. Also toss any with cracked or broken shells. After: discard any mussels that stayed closed during cooking. A mussel that won't open after 5-7 minutes of heat was dead before it hit the pot and isn't safe to eat. And one more thing: mussels are highly perishable. Eat them the day you buy them and refrigerate leftovers immediately. Cooked mussels last about a day in the fridge, not longer. There's an old wives' tale about only eating shellfish September through April, but that's just a tale.
