Hosts cooking at the last minute
If you can’t plan ahead for defrosting, Picard’s product information says its fillets can be cooked straight from frozen, including in a frying pan, in the oven or by steaming.
For last-minute cooking, choose fillets whose product information says they can be cooked from frozen. If you’re planning the meal in advance, fillets that need to be defrosted in the fridge may be a good option. Then check the pack size, whether they have skin or bones, and the product-specific instructions. Raw or lightly cooked preparations need extra care: the word ‘frozen’ alone doesn’t mean a fillet is safe to serve raw.
If you can’t plan ahead for defrosting, Picard’s product information says its fillets can be cooked straight from frozen, including in a frying pan, in the oven or by steaming.
If you have time to defrost the fillets in the fridge before cooking, écomiam recommends defrosting them for 4 to 6 hours, followed by cooking in a frying pan, on the barbecue or in the oven.
If you want to serve portions more easily to guests who are concerned about bones, look for an explicit ‘boneless’ label. Pomona PassionFroid offers a product labelled this way, but it comes in a 3 kg case.
Start by considering how much time you have before cooking. Then check the pack size and storage instructions against the number of guests and the space in your freezer.
| Criteria | What to check | Who is it for? |
|---|---|---|
| Cooking plans | Check whether the product information says the fillets can be cooked from frozen or need to be defrosted in the fridge, as well as the cooking methods listed. | When I’m preparing dinner that same evening, I want to be able to cook the fillets without waiting several hours. Around 42% of consumers prioritise this flexibility. |
| Storage and cooking | Check the storage and defrosting instructions on the pack. For a raw or lightly cooked dish, don’t assume that freezing is enough. | If I’m preparing the fillets in advance, I want to manage their storage safely until serving. This is the main concern for around 33% of consumers. According to the Anses, cooking and freezing do not destroy histamine that has already formed. |
| Bones and pack size | Look for an explicit ‘boneless’ label if needed, then check whether the fillets have skin and compare pack weights. | When serving portions with less picking through at the table, I look for clear information about bones and a pack size that suits the number of guests. Around 25% of consumers put this need first. |
These products have different storage requirements and need different preparation. So if a recipe calls for a raw fillet to be cooked, don’t choose a product based only on the word ‘mackerel’.
Look for the frozen-food label and check the condition of the fish and the cooking instructions before you buy.
A product’s instructions may only recommend cooking. For fish eaten raw, the Anses recommends freezing it at −18 °C for at least seven days to protect against certain parasites. The word ‘frozen’ alone doesn’t tell you whether these conditions have been met.
If your recipe calls for raw or lightly cooked fish, check the precautions for that preparation rather than assuming it’s suitable because it’s frozen.
The products featured here range from 500 or 600 g bags to a 3 kg case. The larger size needs more freezer space and some planning around your meal.
Compare the weight with the number of guests and the space available in your freezer. Once defrosted, follow the product’s instructions.
The word ‘fillet’ alone doesn’t confirm that a product is boneless. Pomona PassionFroid’s product information makes this clear, while you’ll need to check the details for the other fillets individually.
If this matters when serving, look for an explicit ‘boneless’ label on the product you choose.

The fact that they’re labelled as frozen isn’t enough to decide whether to serve them raw. For fish eaten raw, the Anses recommends freezing it at −18 °C for at least seven days to destroy certain parasites. You should also take particular care if serving raw fish to anyone who is sensitive to it.
Poor storage can encourage histamine to form in mackerel. According to the Anses, neither cooking nor freezing destroys histamine that has already formed. Follow the storage instructions and don’t leave defrosted fillets at room temperature.
For unprocessed fishery products in France, the DGCCRF lists details including the commercial name, scientific name, production method, fishing area, fishing gear category and whether the product has been defrosted. When choosing your fillets, also check the weight, whether they have skin or bones, and the product-specific preparation instructions.
Picard’s product information says never to refreeze a defrosted product. For other products, follow the instructions on the pack and defrost only the amount you need for your meal.
