Who are these sizes suitable for?

Students having lunch without access to a kitchen

Pre-cooked canned lentils can be served cold according to the instructions or heated if you have access to the right equipment, making lunch easy to prepare with very little. A small can means you won’t have to deal with leftovers.

Students planning several meals

A large can can be split between two meals, provided you can transfer the leftovers to a suitable container and refrigerate them as instructed on the product.

Shoppers who pay close attention to ingredients

Check the ingredients, salt content and allergen information for each product: plain lentils and a ready-made recipe won’t necessarily have the same ingredients.

What should you check before buying?

Small cans of plain lentils

Choose these: for an individual lunch when you have no reliable way to store leftovers.

Bear in mind: you’ll need to add your own seasoning or side dish.

Large can of plain lentils

Choose this: for several meals or a shared lunch, if you can refrigerate the leftovers.

Bear in mind: the storage instructions after opening are especially important.

Ready-made lentils

Choose these: when a pre-seasoned recipe better suits the time you have available.

Bear in mind: the ingredients and salt content depend on the specific recipe.

Mistakes to avoid

  • Opening a large can for one lunch without planning what to do with the rest

    A 530 g can may leave you with more than you can use if you don’t have access to a fridge. The Auchan and d’Aucy product information cited for certain products says to transfer leftovers to a suitable container, refrigerate them and eat them within two days.

    If you haven’t planned a second meal, consider a smaller size instead. Otherwise, follow the instructions on the can you buy as soon as you open it.

    Any portion that can’t be stored may end up being thrown away.

  • Confusing plain lentils with ready-made lentil recipes

    The Auchan ready-made recipe cited here contains carrots and onions, among other ingredients. Its product information lists 0.93 g of salt per 100 g, compared with 0.58 g for the 530 g Auchan plain lentils checked. These figures apply to those two products, not to every canned product in their categories.

    Choose based on how much preparation you want to do, then compare the ingredients and nutritional information for the products you’re considering.

  • Going by the can’s total weight alone

    When lentils are packed in liquid, the total weight includes the liquid. The drained weight helps you compare how many lentils you’ll get for your meal; the DGCCRF states that this information appears on the labels of relevant food products.

    Check the drained weight and compare it with the number of meals you plan to make.

  • Assuming the word ‘lentils’ tells you which allergens are present

    Depending on the product, the Auchan and Bonduelle product information checked mentions that traces of cereals containing gluten or soya may be present.

    If you need to avoid an ingredient, check the ingredients list and allergen information on the can you receive.

Brands to compare

Bonduelle

Plain lentils in 265 g and 530 g sizes, to suit the number of meals you’re planning.

  • Bonduelle says its 530 g Lentilles Jus Nature are pre-cooked and can be served cold or heated.
  • The Carrefour product information for 265 g Bonduelle lentils mentions that traces of soya and cereals containing gluten may be present. Check the specific product you buy.

Carrefour Classic'

A pack of three cans, each with a drained weight of 130 g, worth considering if you want to split your lunches into separate portions.

  • Each can is a separate portion to open for one meal.
  • Check the ingredients and instructions for the product you choose before deciding how to serve it.

ECO+ / E.Leclerc

A 530 g can of lentils to consider if you’re planning several meals or a shared lunch.

  • You can split the 530 g size between meals if you follow the storage instructions for leftovers.
  • For an individual lunch, check how much will be left and what the instructions say about storage after opening.

Auchan

Two products suit different needs: 530 g of plain lentils and a 400 g ready-made recipe with carrots and onions.

  • The choice between plain and ready-made lentils lets you decide whether to add your own seasoning.
  • Ingredients may vary between products, so check the label of the one you receive, especially for salt and allergens.

Frequently asked questions

Can you eat canned lentils cold at uni?

Yes, if they’re pre-cooked and the instructions say they can be served that way. The product information for Auchan plain lentils recommends draining and rinsing them before serving cold; always follow the instructions on your can.

What should you do with leftover lentils after opening?

Follow the storage instructions on the can you buy. For the Auchan and d’Aucy products mentioned, these say to transfer the leftovers to a suitable container, refrigerate them and eat them within two days.

Do you have to throw away a can if its best-before date has passed?

No, not automatically if the packaging is intact. The DGCCRF distinguishes between a best-before date and a use-by date. Check the condition of the can and follow the product instructions before using it.

How can you compare the amount of lentils in two cans?

If the lentils are packed in liquid, compare their drained weights rather than their total weights. This makes it easier to match the amount of lentils to the number of meals you’re planning.

Are canned lentils always free from gluten and other allergens?

No. It depends on the product and its labelling. Some Auchan and Bonduelle product information mentions that traces of cereals containing gluten or soya may be present. If you need to avoid these ingredients, check the specific product packaging.
