Expert Tips for Properly Storing Mussels Overnight: A Complete Guide

Mussels are a delicious and healthy seafood option that can be cooked in many different ways. If you’re planning to cook mussels for a special dinner or event, you may need to store them overnight before cooking. Proper storage is crucial to ensure the safety and quality of your mussels. In this blog post, we will share some tips on how to store mussels overnight.

Buy fresh mussels

The first step in storing mussels overnight is buying fresh ones. When purchasing mussels, look for tightly closed shells and avoid those with cracked or broken shells. Check the smell as well; fresh mussels should have a briny scent.

How-to-tip: Smell Test

To perform a smell test, put the shellfish close to your nose and take a whiff. Fresh shellfish has an oceanic aroma while decaying ones have an unpleasant odor.

Clean your Mussels

Before storing your mussels, it’s essential to clean them properly. Scrub off any debris or barnacles from the shells under running water using a stiff brush like nylon-bristled brush.

How-to-tip: Debeard Mollusks

Mussel ‘Beards’ refer to hairy filaments sticking out between their two halves of shells which they use for attaching themselves onto rocks or other substrates in their habitat.
1) Hold each mussel firmly by its hinge
2) Grab onto the beard
3) Move it back toward the hinge until it comes off

The best way store Mussles Overnight

After cleaning, place your fresh live mussel into an open container such as Tupperware containers covered lightly with moist towels/napkins over them but not sealing completely since they must breathe through tiny openings found at the tip of their shells. To keep them fresh, make sure they stay in a cool environment with temperatures between 1-4 Celsius.

How-to-tip: Keep Mussels in Water

Place mussels inside a large bowl filled with salted water and cover it with cling film or plastic wrap that has air holes to allow some ventilation. You can also place ice on top of the wrapped container to keep it cooler.


Storing mussels overnight requires proper handling from purchasing until cooking. Remember always to buy fresh ones, clean, and store them properly in an open container covered lightly with moist towels/napkins before placing them into the fridge where temperature is optimum for preservation purposes only! With these tips, you’ll be sure to have deliciously cooked mussels every time you decide to prepare them at home!
