Who is this guide for?

Hosts who want oysters to take centre stage

You’d rather let guests season the mackerel themselves than serve a sauce that everyone has to use. Auchan’s listings for Petit Navire and Saupiquet plain mackerel multipacks show mackerel, water and salt as the ingredients.

Guests planning a second course

You’re planning to serve the mackerel separately, with bread, salad or potatoes. A grilled or olive oil variety already has its own seasoning, so choose one to suit your guests’ tastes.

Shoppers who check ingredients carefully

You’re stocking up for a meal with others and want to know what’s in each variety before serving it. Depending on the product, the ingredients may include mustard or sulphites. Check the specific tin, not just the brand.

What should you look for?

First, decide whether the mackerel should be a subtle accompaniment or a separate course. Then check the ingredients, how much you’ll need to open and the storage instructions.

What to considerWhat to checkWho this matters to
Its place in the meal Choose a plain variety if you want to season it separately, or a grilled or sauced variety for a separate course. If oysters are the main event, I want to serve the mackerel without a set sauce. Around 36% of consumers would make this their top priority.
Ingredients Read the ingredients for the specific variety. Some mustard or white wine varieties also list mustard or sulphites. For a meal with others, I want to know what’s in each tin before serving it. Checking the ingredients would be a priority for around 29% of consumers.
Multipack size Compare the tin weight and, if listed, the drained weight with the portions you’re planning. If the mackerel is just an accompaniment, I’d rather open the right amount and keep the other tins sealed. Around 21% of consumers would put pack size first.
Leftovers after opening Check the storage time and temperature on the packaging before opening several tins. I want to be able to use any leftovers as directed, without opening more mackerel than I need. Around 14% of consumers would prioritise this.

Mistakes to avoid

  • Assuming every variety from a brand is the same

    Auchan’s listing for Petit Navire plain fillets shows mackerel, water and salt, while Carrefour’s listing for Petit Navire mackerel with mustard also includes mustard.

    If you’re serving it as part of a meal with others, check the ingredients for the specific variety and pack size you plan to serve.

  • Looking only at the three tins in the multipack

    The sizes listed by Auchan and Carrefour include 3 × 95 g, 3 × 110 g, 3 × 120 g and 3 × 169 g. So the same number of tins doesn’t necessarily mean the same amount of mackerel.

    Compare the total weight with the number of portions you need, and check the drained weight too if it’s shown on the label.

  • Storing an opened tin as if it were still sealed

    Auchan’s listings for Petit Navire and Saupiquet plain mackerel say to refrigerate the product after opening and eat it within two days or 48 hours, depending on the product.

    Follow the instructions on your tin and transfer any leftovers to a suitable food container.

    Opening too many tins at once can lead to waste if you don’t use the leftovers within the stated time.

Brands to know when comparing varieties

Petit Navire

Multipacks of plain, simply grilled and mustard mackerel fillets let you choose how much seasoning you want.

  • Auchan and Carrefour listings include multipacks of plain fillets at 3 × 95 g, simply grilled fillets at 3 × 110 g and mustard fillets at 3 × 169 g.
  • Ingredients vary by variety. In particular, check whether the product you’re considering contains mustard.

Saupiquet

The brand offers a plain multipack as well as grilled fillets in olive oil, giving you two distinct ways to serve mackerel.

  • Auchan and Carrefour listings show the plain multipack at 3 × 169 g and the grilled olive oil variety at 3 × 120 g, respectively.
  • Which multipack you choose depends on the portions you need and how much of an oil-packed variety you want to serve with the meal.

Carrefour Extra

This own-brand range includes several mackerel varieties, including a plain option.

  • Comparing the variety names helps you tell a plain preparation from one that’s already seasoned.
  • Before choosing a multipack, check its size and ingredients on the listing for the specific product.

Pêche Océan / Marque Repère

These own brands are worth comparing when looking at the everyday mackerel varieties sold by E.Leclerc.

  • The variety you choose will determine whether you serve the mackerel simply or as a dish that’s already seasoned.
  • Don’t assume one product has the same ingredients as another. Always check the label on each product.

Auchan

Auchan’s own-brand range includes a 120 g pack of plain mackerel fillets.

  • Its listing states that it contains 99% mackerel fillets and salt, so you can choose how to season it when serving.
  • The same listing says to refrigerate the product after opening and eat it within two days.

Frequently asked questions

Which mackerel variety should I serve with oysters?

Plain fillets let you choose the condiments when you serve them. The Petit Navire and Saupiquet products listed by Auchan contain mackerel, water and salt. If you’re planning a separate course, a grilled, oil-packed or sauced variety could also work, depending on your guests’ tastes.

Will a pack of three tins be enough for dinner?

The number of tins alone won’t tell you; it depends on the portions you’re planning and how the mackerel fits into the meal. The multipacks listed by Auchan and Carrefour range from 3 × 95 g to 3 × 169 g. Compare the drained weight too, if it’s given.

How long can you keep mackerel after opening?

Follow the storage time and temperature on the packaging for your product. Auchan’s listings for Petit Navire and Saupiquet plain fillets say to refrigerate them and eat them within two days or 48 hours of opening.

Can mackerel contain allergens other than fish?

Yes. Ingredients vary by variety: Carrefour’s listing for a Petit Navire mustard variety includes mustard, while an E.Leclerc listing for mackerel in white wine mentions sulphites. Before serving, check the ingredients and any ‘may contain’ warnings on the specific packaging.
