How to Cook Mussels: Methods, Times & Recipes
Mussels cook in about 5-7 minutes and are done when the shells open. The most popular methods are steaming. Below are step-by-step guides for every way to cook mussels, with exact times and temperatures.
The best way to cook mussels
You can cook mussels by steaming. Clean and debeard mussels just before cooking, and discard any that stay shut after steaming.
There is no single “best” method — it depends on the cut and the result you want. Quick, high-heat methods like searing and grilling give colour and a little char, while gentler methods like baking, steaming and poaching keep mussels moist and forgiving. Each guide below walks through one method in full, with the exact timing and doneness cues for it.
How to tell when mussels is done
The single most important thing with mussels is not to overcook it. Seafood goes from perfectly done to tough and dry in a matter of seconds, and it keeps cooking from residual heat even after it leaves the pan. Watch for the visual cue — mussels are ready when the shells open — and take them off the heat a touch before they look completely done so carry-over heat can finish the job.
Buying and storing Mussels
Live mussels need to stay alive until you cook them, so keep them cold in a bowl loosely covered with a damp cloth — never sealed in a plastic bag or submerged in fresh water, both of which will kill them. Before cooking, tap any that are open; a live one closes up, and any that stay open (or have cracked shells) should be thrown out. After cooking, discard any that never opened. Use mussels within a day or two of buying for the best flavour and safety.
