Preparing Frozen Half Shell New Zealand Greenshell™ Mussels

Frozen New Zealand Greenshell™ Mussels should be thawed before cooking.

Conventional thawing can be achieved by placing mussels or sealed bag in the refrigerator for 5-8 hours. Draining off excess liquid once thawed.

Alternatively quick thawing can be achieved by running cold water over mussels for 10 minutes, moving them around to ensure all are properly defrosted.

Cooking Methods

Care should be taken not to overcook New Zealand Greenshell™ Mussels with the best results achieved when cooked until just heated through.

To Steam

Place two cups of water in a large pot and cover with a tight fitting lid. Bring to the boil and add the mussels, replace the lid and over a high heat, steam for 3-5 minutes before removing from the pot.

To Bake

Set the half shell mussels on to a baking tray. Place into the oven (approx 160°C/320°F) & allow to bake for approx 5-7 minutes, or until all the mussels are evenly hot.

To Grill

Place the half shell mussels with topping of choice under a hot grill (or bake in a hot oven 180 °C / 350 °F). The amount of cooking time will vary depending on the topping, however as an indication should take around 2 – 5 minutes.


Once thawed, use New Zealand Greenshell™ Mussels immediately. New Zealand Greenshell™ Mussels must not be refrozen.

Frozen New Zealand Greenshell™ Mussels will retain their quality until the specified pack expiry date if stored correctly at or below 0°F (-18°C).
