Sugar-label-first shoppers
If avoiding added sugar is your priority, the claim on the front of a jar is only part of the choice. Compare the declared sugars per 100g across similar sauces to see what each contains.
Who is choosing this sauce?
Family breakfast cooks
For a dish shared by several people, a smooth texture, vegetable ingredients, flavour and stated serving count may matter alongside the sugar label.
Small-household jar users
If breakfast uses only part of a jar, check the pack size and how soon the label says to use the remainder after opening.
What matters when buying?
For a tomato sauce, settle the sugar-label requirement first, then choose a flavour and jar size that fit the dish and the amount your household will use.
| Concern | What to check | Who this matters to |
|---|---|---|
| Sugar wording and amount | Read the exact claim and compare ‘of which sugars’ per 100g across similar ready-to-use sauces. | If avoiding added sugar comes first, I still want to know how much sugar the tomato sauce contains. About 46% of consumers put understanding the claim and sugar figure first. |
| Flavour and portions | Check the ingredients, texture and stated servings against the dish you plan to make. | For a breakfast dish shared with family, I need a flavour and texture people will want to eat, with enough sauce to go round. About 36% of consumers make that fit their primary concern. |
| Using the opened jar | Compare pack size with the amount you will use, and follow the jar's refrigeration and use-within instructions. | When I need only a little sauce, I do not want the remainder to sit open longer than its label allows. Around 18% of consumers put managing leftovers first. |
What is easy to overlook?

Reading ‘no added sugar’ as ‘no sugars’
Tomato sauces with a no-added-sugar claim can still declare sugars. The checked Sainsbury's, Loyd Grossman and Tesco products list 3.9g, 4.0g and 4.5g sugars per 100g respectively.
Read both the claim and the nutrition panel, comparing similar sauce types on a per-100g basis.
-
Buying more sauce than the meal needs
The checked jars differ in size and in their stated periods for use after opening. A larger jar is less practical if you cannot use the remainder within its label instructions.
Choose a pack size that fits your plans, then check how the opened jar must be stored and when it must be used.
-
Assuming the sugar figure tells you the salt figure
The checked Sainsbury's, Tesco and Loyd Grossman sauces list different amounts of salt per 100g, from 0.61g to 0.73g. The sugar claim does not settle that comparison.
If salt also matters to your choice, read its per-100g value and consider the portion you intend to use.

Relying on an older product listing
A Tesco listing for Dolmio Original Bolognese Pasta Sauce No Added Sugar 500g was marked out of stock when checked; that does not establish its availability now.
Confirm the current listing and read the label on the exact jar before substituting it for another sauce.

- Its after-opening instruction says to refrigerate and use within 7 days.
Asda
Asda Groceries lists a 350g Loyd Grossman No Added Sugar Tomato & Basil sauce; this is a branded product sold by Asda, not an Asda own-label sauce.

Joybuy product selection
This carbonara pasta-bake sauce is an option for a cooked weekend dish. It is a different sauce style from the tomato products above, so its sugar figure should not be treated as a like-for-like tomato-sauce comparison.

Homepride No Added Sugar Carbonara Pasta Bake 485g
Consider this 485g carbonara pasta-bake sauce if that flavour fits your cooked dish rather than a tomato sauce. Check the ingredient and allergen information, the nutrition panel and the instructions for using the jar after opening before buying.
Questions about labels and storage
Does ‘no added sugar’ mean a pasta sauce contains no sugars?
No. The checked no-added-sugar tomato sauces from Sainsbury's, Tesco and Loyd Grossman still list between 3.9g and 4.5g sugars per 100g. Read the nutrition panel as well as the claim.
Are ‘reduced sugar’ and ‘no added sugar’ interchangeable when shopping?
No. If avoiding added sugar is your requirement, look for that exact wording on the product you intend to buy, then read its ingredients and declared sugars per 100g. A sugar figure alone does not establish that nothing was added.
How long can I keep an opened jar?
Follow the instructions on the exact jar. The checked Tesco sauce says to consume within 14 days after opening, the Sainsbury's sauce within 7 days and the Loyd Grossman sauce within 3 days; each directs refrigeration after opening.
What else should I check for a breakfast-style dish?
Check whether the sauce's flavour, ingredients, allergens, pack size and cooking instructions fit the dish you plan to make. If you will use only part of the jar, include its after-opening instructions in that decision.
