Freeze and thaw oysters to effortlessly open their shells They'll die, and the second they thaw, they open," Croxton told Food & Wine. Croxton advises completely freezing the oysters, then moving them to the refrigerator. Once thawed, the shells pop open on their own.
Oysters may be frozen, but once thawed, the texture of the meat, becomes softer and the oysters are generally not suitable for raw consumption. Frozen oysters, however, are quite acceptable when they are cooked.
Freezing and thawing is the easiest hands-off method of opening oysters, according to Croxton.
To defrost for half shell consumption: Place in the fridge on a sheet pan on a single layer, defrosting can take up to 18 hours. Do not place at room temperature or thaw in water. After thawed you can slurp right away, frozen oysters are consumable for 2-3 days after thawing in the fridge.
If the shell remains shut after cooking, that just means the muscle that holds the shell together is working! Sometimes that means it's still alive and just hasn't been cooked enough to die yet, or the muscle is so joined to the shell that it's not letting go even after cooking and killing the oyster.
“We know that oysters open their valves when there is food,” she says, and previous research has shown that the movement of plankton, which oysters filter out of seawater and consume, is influenced by moonlight.
Freezing does change the texture and flavor of oysters. These oysters may be best used in casseroles or stews. This document was extracted from "So Easy to Preserve", 6th ed. 2014.
Remove oysters from the freezer and submerge them in a pot of ice water with the plastic bag for 10 minutes for every dozen of oysters. We do not recommend soaking the oysters directly in the water. Clean and scrub the oysters shell to remove any sand or shell fragments.
If you know you aren't going to eat the oysters for a bit, just shuck and freeze them. Use a freezer safe container, shuck them, stick as much liquor in the container as you can and then add water to cover the oysters. If you want to store them in a cooler for whatever reason, that is perfectly fine.
Five minutes in a hot oven makes oysters pop right open—no brute strength or raw-bar expertise required. Published Oct. 7, 2021. With the right technique, a proper knife, and a little muscle, most anyone can pry open an oyster's tightly clamped shell—but it takes practice to do it efficiently and confidently.
They freeze beautifully. You can freeze the oysters directly in the jar or bag they arrived in or you can transfer them to a ziplock freezer bag. Try to use within 3 months. Some of our favorite recipes for shucked oysters include fried, oyster casserole, or in an oyster roll.
Oysters will die if they sit in fresh water. You can keep them on a tray of ice for an hour or so but avoid letting them sit in a puddle of fresh water.
Storing Oysters
You can refrigerate freshly-shelled oysters in their own liquor (the liquid they sit in) for two days, but use them as quickly as you can. You can freeze shucked oysters but never freeze oysters in their shells. Frozen raw shucked oysters will keep for up to three months.
Can You Refreeze Oysters? No, you should only freeze oysters once, like most shellfish. Generally, the best way to enjoy oysters is when they're fresh out of the water and can be enjoyed raw. However, if you want to keep them for more than a couple of days, freezing them is your best option.
Unless you are going to eat your oysters straight away, it's better to buy them unopened. Given the proper care, oysters will live for 5-7 days after being harvested. You can keep live oysters in the fridge. To ensure maximum quality, put them under a wet cloth.
Once people have polished off the first round of oysters, dump out the semi-melted crushed ice in the serving bowl, and replenish with the extra crushed ice you processed earlier. Transfer the second round of shucked oysters from the sheet tray to the bowl of crushed ice. Rinse and repeat until you're out of oysters.
Additionally, freezing oysters can alter their flavor so that it tastes a little more fishy, and the texture can turn softer and become mushy, affecting how you can use them (via canyoufreezethis.com). The National Center for Home Food Preservation cautions that you should only freeze oysters still in the shell live.
Crunchy outside and juicy inside, Deep-fried Crumbed Oysters is one of the best ways of eating oysters in my view. Shucked oysters are very fresh but expensive, so I used frozen oysters to make Deep-fried Crumbed Oysters.

Cover the oysters with a damp paper towel or damp cloth and place them in the fridge. They should keep for up to seven days like this, but it's best to eat them within a day or two.
The ice keeps the oysters upright so that they don't lose their shell liquor and it keeps them cold. Chilled oysters safer to eat and they taste better. Any cocktail, mignonette, or other sauces should also be chilled. Shuck the oysters and carefully place them on the ice.
"When you slurp back oysters raw, they are still alive or just freshly killed or shucked prior to serving, which is why you oftentimes see them on ice," says Alex Lewis, RD, LDN, a dietitian for Baze. This ensures they are fresh when eating, so they maintain the right flavor profile, texture and nutrient density.
In the case of oysters, this little mollusk contains so much zinc that it should only be eaten occasionally. Eating them once or twice a week should land you in a nutritional sweet spot. Make sure you balance your zinc intake with enough copper — especially if you really enjoy oysters!
