For pie and mash night, a 4 x 400g pack makes sense if you expect to use several cans across this meal and later meals: you can open one can at a time. Choose standard chopped tomatoes for a sauce you are happy to break down yourself, or finely chopped tomatoes for a finer starting texture. Check each product’s instructions for storing any contents left after opening.
Four separately sealed 400g cans let you open the amount needed for the sauce and keep the remaining cans unopened. A 4 x 400g pack contains 1.6kg in total, but the number of portions depends on your recipe and how much sauce you serve.
If another tomato-based meal is planned, a multipack keeps more 400g cans ready without requiring you to open them all for pie and mash night. Choose the pack quantity around the meals you expect to make.
Finely chopped tomatoes may suit a sauce where visible tomato pieces are less welcome. Cirio describes its Polpa Finissima as very finely chopped and thick; that is the manufacturer’s description, not a comparison of finished sauces.
Start with the amount of sauce you plan to make, then choose the tomato cut and check what the label says about any contents left after opening.
| Priority | What to check | Your needs |
|---|---|---|
| Pack format | Check the number of cans and weight per can. Four 400g cans contain 1.6kg in total, but a labelled serving size does not tell you how much sauce your recipe will make. | I want enough tomatoes for this meal while keeping cans I do not need unopened for another recipe. |
| Tomato cut | Check whether the tomatoes are standard chopped, finely chopped or whole peeled. Whole tomatoes need breaking down if the recipe calls for a finer sauce. | For a less chunky sauce, I would rather start with a fine cut than break down larger pieces myself. |
| Ingredients | Read the ingredients on the particular can. Tesco and Sainsbury’s describe their standard chopped examples as tomatoes in tomato juice; descriptions for other products may differ. | I want to know what is in the tomato base before adding it to my pie and mash sauce. |
| After opening | Follow the individual product’s storage and open-life instructions. Sainsbury’s directs shoppers to refrigerate its opened chopped tomatoes and use them within 2 days; instructions differ between products. | If a can is not used up at dinner, I need a plan for the remaining contents that follows its label. |
A four-can pack keeps its unused cans sealed, but opening a can starts the product-specific storage period for its contents.
Open only what the sauce needs. If any contents remain, transfer and refrigerate them as the label directs, and plan when you will use them.
Descriptions of thick or finely chopped tomatoes describe a product’s starting texture; they do not establish how every finished pie and mash sauce will taste.
Choose the cut you want to cook with, and consider a single can if you are trying an unfamiliar texture for the first time.
GOV.UK distinguishes best-before dates, which concern quality, from use-by dates, which concern safety. A date on an unopened can does not replace its instructions for storing contents after opening.
Check the can and follow its storage directions, including the stated period for using opened contents.
These examples describe particular tomato products, not every product made by each brand.
Tesco Italian Chopped Tomatoes are listed as a 4 x 400g own-label pack.
Sainsbury’s Italian Chopped Tomatoes are listed in four separate 400g cans.
Napolina Chopped Tomatoes are listed in a 4 x 400g pack for cooks who want standard chopped tomatoes.
Cirio Polpa Finissima is a 4 x 400g finely chopped tomato option.
Mutti Polpa is listed as a finely chopped tomato product, including a 4 x 400g pack.
These packs offer chopped, finely chopped and whole peeled tomatoes for planning a pie and mash sauce. Most contain four 400g cans; the six-can Napolina pack is a larger option for cooks who expect to use more tomatoes.

Four 400g cans let you open chopped tomatoes for the sauce as needed. The product description identifies tomatoes in tomato juice; follow the label’s directions for transferring and refrigerating opened contents and using them within 2 days.

This four-can pack offers a finer tomato cut as a starting point for sauce. The product description directs you to refrigerate opened contents and use them within 5 days; check the can label for its instructions.

Four 400g cans provide a multipack quantity, but these are whole peeled plum tomatoes rather than chopped tomatoes. Break them down if your sauce needs a finer texture. The product description directs you to cover and refrigerate opened contents and use them within 2 days.

These four 400g cans contain peeled tomatoes for a sauce in which you are prepared to break down whole tomatoes. Check the current can label for ingredients, allergens and storage instructions, particularly if allergens matter to your household.

Six separate 400g cans suit a plan that uses chopped tomatoes beyond pie and mash night; this is a larger pack than the four-can options. The product description directs you to transfer and refrigerate opened contents and use them within 2 days.
A 4 x 400g pack contains 1.6kg of tomatoes in total, with each can sealed separately. Do not treat a labelled serving count as the amount of pie and mash sauce you will make: that depends on your recipe and portion sizes.
Choose standard chopped tomatoes if you are happy to simmer or break down the pieces to reach your preferred texture. Finely chopped tomatoes provide a finer starting cut; a manufacturer’s texture description is not a guarantee of how your finished sauce will taste.
Follow that product’s label rather than applying one storage period to every brand. Sainsbury’s instructs shoppers to transfer its opened chopped tomatoes to a non-metallic container, refrigerate and use within 2 days; other product instructions differ. GOV.UK also advises following the manufacturer’s open-life instructions.
GOV.UK says a best-before date concerns food quality, whereas a use-by date concerns safety. Check the condition of the can and its label, and follow the product’s storage instructions, especially after opening; the best-before date is not an opened-can storage period.
