One-person desk-lunch buyers
A 200–220g tin may be easier to use in one sitting. If you choose a larger tin, plan where you will refrigerate the remainder and follow that product’s opened-pack instructions.
Who is each option for?
People stocking the cupboard for several lunches
A larger tin or multipack is worth considering when you will use its contents across meals. Check the size of each individual tin, not just the total pack weight.
Shoppers comparing sugar and salt labels
Look for the reduction’s stated comparison product, then compare sugars, salt and ingredients per 100g on the exact tins you are considering.
What should you check?
Start with how much you will use at lunch, then check the recipe and what you can do with an opened tin.
| Priority | What to check | Your needs |
|---|---|---|
| Tin size | Compare the weight of each tin, including tins within a multipack. Check the labelled number of servings if you intend to use only part of one. | A smaller tin suits me if I want one lunch without an opened tin to take home. I can consider a larger one if I will use the remainder. |
| Recipe | For reduced sugar or salt claims, read the named comparison recipe, ingredients and per-100g sugars and salt. Sainsbury's says its 400g reduced recipe has 30% less of each than its own standard baked beans; that is not a comparison with other brands. | I want to know what the stated reduction means for the particular tin I am buying, rather than relying on its front-of-pack wording alone. |
| Leftovers | Read the exact pack’s instructions for transferring, refrigerating and using opened contents. The checked Heinz and M&S product instructions give different use-within periods. | If I cannot refrigerate an unfinished tin, I would rather choose an amount I can use at lunch. |
| Heating | Check the product’s heating directions and whether you have a suitable dish and the required facilities at work. The checked Sainsbury's and Heinz instructions call for a microwaveable dish or container. | I need a way to prepare the beans with the equipment available at my desk-lunch location. |
Common buying mistakes
-
Assuming a smaller tin is always the practical choice
A small tin avoids an opened remainder, while a larger one can cover more than one meal if you can store it as directed.
Decide how much you will eat at lunch and whether you can use the rest before choosing a size.
-
Treating reduced-recipe claims as interchangeable
Sainsbury's states a reduction against its own standard beans; the checked Heinz No Added Sugar recipe uses different wording and lists a sweetener. The claims do not describe the same comparison.
Read the named comparator, ingredients and per-100g sugars and salt on each tin.
-
Leaving unused beans in an opened tin
The checked product instructions call for unused contents to be transferred to a suitable container and refrigerated, with a use-within period that varies by product.
Follow the instructions on your tin. If you cannot store leftovers as directed, choose a smaller format or share a larger one.
-
Counting a larger serving as multiple 5 A Day portions
The NHS says beans and pulses count as no more than one 5 A Day portion per day, regardless of the amount eaten.
If you are counting portions at lunch, do not count extra beans as an additional portion.
Brand and range references
Tesco
Tesco lists standard and reduced sugar and salt own-label baked beans in 420g tins.
- Both listed recipes offer the same tin size for a like-sized choice.
- Check the exact recipe label rather than assuming their ingredients and nutrition are identical.
Waitrose Essential
The Essential range includes listed 420g standard and reduced salt and sugar baked-bean tins.
- The two listed 420g formats let you compare standard and reduced recipes at the same pack weight.
- Confirm the recipe and pack size of the individual tin you select.
Sainsbury's
Its 400g reduced sugar and salt baked beans state 30% less sugar and 30% less salt than Sainsbury's standard baked beans.
- The Sainsbury's product label lists 2.8g sugars and 0.29g salt per 100g.
- The stated reduction is against Sainsbury's own standard recipe, not every standard tin.
Heinz
Heinz has standard and No Added Sugar baked-bean recipes among the checked listings.
- The checked No Added Sugar label lists 1.9g sugars and 0.4g salt per 100g.
- No Added Sugar describes that recipe; check its ingredients and label rather than treating it as interchangeable with the standard tin.
M&S
The checked range includes a 400g standard tin and a 220g Only 7 Ingredients tin.
- The two listed sizes offer different amounts to consider for one lunch.
- Follow the storage directions for the exact product: the checked standard and 220g tins have different opened-pack use-within periods.

Desk-lunch questions
Is a 400–420g tin one lunch portion?
Not necessarily. Sainsbury's describes its checked 400g reduced-recipe tin as two servings. If you expect to eat only part of a larger tin, check how you will store the remainder; a 200–220g format may avoid that step.
Do reduced-sugar-and-salt labels mean the same thing across brands?
No. Sainsbury's states that its checked reduced recipe has 30% less sugar and salt than its own standard baked beans, while the checked Heinz product is labelled No Added Sugar and has its own ingredients and nutrition values. Compare each tin’s per-100g label and the stated basis for any reduction.
Can baked beans count towards 5 A Day?
Yes. NHS guidance includes baked beans in tomato sauce, but says beans and pulses count as no more than one 5 A Day portion per day, regardless of how much you eat.
How should I store beans left in an opened tin?
Follow the instructions for that product, including transferring unused beans to a suitable container and refrigerating them. The checked Heinz instructions say to use leftovers within two days; the checked M&S standard product gives three days, so do not apply one tin’s period to another.
Can I microwave baked beans in the tin?
No. Transfer them to a suitable microwaveable dish or container and follow the pack’s heating directions. The checked Sainsbury's and Heinz instructions specify a microwaveable dish or container rather than the tin.
