One-person grocery shoppers
A 200g or 220g tin is worth considering when you want beans for one meal or side dish without routinely storing the remainder. Check the weight rather than assuming every single tin is a single serving.
Who might choose each tin?
Shoppers planning more than one portion
A 410g or 420g tin can work when you will share it or use what remains. The essential Waitrose 420g listing describes two servings and says to refrigerate unused contents and use them within two days.
Shoppers comparing recipes
Check the exact tin’s ingredients, allergen information and nutrition panel if sugar, salt or a particular ingredient matters to you. The Heinz No Added Sugar 200g recipe, for example, lists steviol glycosides and 0.80g salt per can on the Waitrose listing.
What should you check before ordering?
Start with the amount you will use, then compare the exact recipe and the substitution choices offered for your order.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Compare the stated net weights: cited small tins are 200g or 220g, while standard examples are 410g or 420g. For a larger tin, read its instructions for unused contents. | I would rather open a smaller tin for one meal, or I can share a larger one and use any remainder within the time on its label. |
| Recipe and salt | Compare salt on the same stated basis, such as per can, per serving or per 100g. The Waitrose listing gives 0.80g per can for Heinz No Added Sugar 200g and lists steviol glycosides. | If I choose a no-added-sugar recipe, I also want to know its salt value and whether it contains a sweetener. |
| Ingredients and allergens | Read the ingredient and allergen information for the exact recipe. Check the delivered tin too, especially if a different product arrives. | My choice depends on what is in this particular tin, not on an assumption that all baked beans have the same ingredients. |
| Substitutions | Review whether the retailer allows substitutions and compare any replacement’s weight, recipe and label before accepting it. | I want the size and formulation I ordered. In a March 2026 Which? survey of more than 3,500 supermarket shoppers, 20% reported receiving a substitution in their most recent online grocery order; that figure is not specific to baked beans. |
What can catch you out?
-
Reading “single tin” as “single serving”
A single can may contain 200g, 220g, 410g or 420g in the cited listings. The essential Waitrose 420g tin is described as two servings.
Check the net weight against the meal you are making. If you expect leftovers, follow that tin’s storage instructions.
-
Assuming no added sugar means no salt or sweetener
The Heinz No Added Sugar 200g listing gives 0.80g salt per can and includes steviol glycosides. Its formulation differs from the conventional Heinz single-serve tin.
Read the ingredient list and compare nutrition values using the serving basis printed on each tin.
-
Accepting a replacement as an equivalent tin
A substitute can differ in pack weight, ingredients and nutrition information, even when it is also labelled baked beans.
Review substitution settings when ordering, then check any replacement against the features that matter to you.
-
Relying only on the listing seen when ordering
The tin delivered may not be the recipe you selected if your order is substituted, and product information can change.
Check the final order and the delivered pack’s label before using it, particularly for ingredients and allergens.

Branston Baked Beans in Tomato Sauce 220g
This 220g can is a smaller-pack option when you do not want a 410g to 420g tin. Decide whether 220g fits your meal; the pack size alone does not establish a serving.

This 390g can suits a larger planned portion or sharing rather than the smaller-tin choice. Its listed recipe contains cheese and milk; check the delivered label if you need to avoid milk, and follow its instructions for any leftovers.
Frequently asked questions
Is a 200g tin always one serving?
No. Waitrose labels its Heinz Baked Beans 200g tin “Single Serve”, but the amount that fits your meal is a separate decision. Check the pack weight and its nutrition panel rather than treating every 200g tin as the right portion for everyone.
Does “no added sugar” mean the Heinz tin contains no salt?
No. The Waitrose listing for Heinz Baked Beans No Added Sugar Single Serve 200g gives 0.80g salt per can and lists the sweetener steviol glycosides. Compare the full label with the recipe you would otherwise choose.
What if my online order contains a different tin?
Check whether the substitute still meets your requirements for weight, recipe, ingredients and allergens before accepting it. Which? reported in March 2026 that 20% of more than 3,500 surveyed supermarket shoppers received a substitution in their most recent online grocery order; the figure is not specific to baked beans.
Where should I check allergens for an online order?
Check the exact product information when ordering and the label on the tin that arrives, particularly if it has been substituted. Do not assume that two baked-beans recipes have identical ingredients or allergen information.
What should I do with beans left in an opened tin?
Follow the instructions on that product’s label. The cited essential Waitrose 420g listing says to refrigerate unused contents and use them within two days; instructions may differ for another tin.
