Who is this for?

Students cooking one dinner

If a recipe uses only part of a tin, decide whether you can use the rest in another meal. That makes the choice between a standard 400g tin and a smaller one more useful than judging the tin size in isolation.

Students sharing a flat dinner

A 400g tin can provide the tomato base for two portions. Asda describes its standard 400g chopped tomatoes as two servings, while the other ingredients determine the finished meal.

Cooks choosing for texture or ingredients

Chopped, finely chopped and plum tomatoes offer different starting forms for a recipe. Compare the exact product names and ingredient lists when the form of the tomatoes matters more than simply having a tin in the cupboard.

What should you check?

Start with the amount and form of tomato the recipe calls for, then plan what you will do with any unused contents.

Priority What to check Your needs
Tin size Compare the recipe quantity with the net contents. Tesco lists both 227g and 400g chopped-tomato tins; Asda describes its standard 400g tin as two servings. I am cooking for two, or I can put the remainder of a 400g tin to use in another meal. If neither applies, a smaller tin may fit the recipe better.
Tomato form Check whether the tin contains chopped, finely chopped or plum tomatoes. These are distinct product descriptions, not interchangeable promises about how a finished sauce will turn out. For a recipe calling for finely chopped tomatoes, I would choose that form deliberately rather than assume every tin has the same texture.
Ingredients and label Read the ingredients, nutrition information per 100g and any allergen information on the actual pack. Asda Groceries lists tomatoes and salt for Mutti Finely Chopped Tomatoes 400g. I need to check whether a particular ingredient suits my recipe or dietary requirements, rather than assume all tinned tomatoes have the same formulation.
Leftovers Read the tin’s instructions for transferring, covering and refrigerating unused contents, including its stated timeframe. Marks & Spencer instructs buyers to use its opened Chopped Italian Tomatoes within three days. If I will use only part of the tin tonight, I can plan a second dish and follow the instructions on the one I buy.

Common buying mistakes

  • Choosing a tin size without checking the recipe

    A 227g tin and a 400g tin leave different amounts available for the meal. A smaller tin may avoid an unwanted remainder, but may not supply enough tomato for a recipe planned around 400g.

    Check the recipe quantity before choosing the tin, and decide whether any remainder has a second use.

  • Assuming every tin has the same texture and ingredients

    Finely chopped tomatoes and plum tomatoes start in different forms. Ingredient lists can differ too: Asda Groceries lists tomatoes and salt for Mutti Finely Chopped Tomatoes 400g.

    Choose the tomato form your recipe calls for and read the specific pack if its ingredients or nutrition information matter to you.

  • Leaving the remainder in an opened tin

    Storage instructions and stated timeframes are product-specific. Marks & Spencer says to transfer its opened Chopped Italian Tomatoes to a non-metallic container, refrigerate them and eat them within three days.

    Before opening a tin you will not finish, check its label and prepare a suitable covered container for the remainder.

Brand and retailer ranges to compare

These examples show differences in tin size, tomato form and labelling; they are not a ranking of how the products taste.

Asda / Just Essentials by Asda

Both ranges include a 400g chopped-tomato tin for recipes using a standard-sized tomato base.

  • Asda describes its standard 400g tin as two servings.
  • Check the label of the particular Asda variant you choose rather than treating the two ranges as the same product.

Tesco

Tesco lists both 400g and 227g chopped-tomato tins, giving shoppers a choice of quantity for a single recipe.

  • The smaller tin is worth considering when the recipe calls for less tomato and the remainder of a larger tin would go unused.
  • Check that 227g is enough before substituting it into a recipe written for 400g.

Sainsbury's / Stamford Street Co.

Sainsbury's lists a 400g Stamford Street Co. chopped-tomato product in tomato juice.

  • Its 400g format can be compared with other standard-sized tins for a two-portion recipe.
  • Read the chosen tin’s ingredients and storage directions rather than applying another range’s instructions to it.

Napolina

Napolina Chopped Tomatoes comes in a 400g tin. Sainsbury's describes the pack as approximately two 200g portions.

  • The stated portion guide can help when planning how much tomato to use in a shared meal.
  • A portion guide describes the tomatoes, not a complete dinner or a cooking result.

Mutti

Mutti Finely Chopped Tomatoes 400g is an option when a recipe specifically calls for finely chopped tomatoes.

  • Asda Groceries lists its ingredients as tomatoes (99.8%) and salt.
  • Check the label if the added salt or the precise ingredient list affects your choice.

M&S

M&S lists a 400g Chopped Italian Tomatoes product.

  • Marks & Spencer provides a specific three-day instruction for its opened product.
  • The instruction also calls for a non-metallic container and refrigeration; check the pack before storing leftovers.

Frequently asked questions

Is one 400g tin enough for a dinner for two?

A 400g tin can provide the tomato base for two portions: Asda and Napolina describe their respective 400g products as approximately two servings. Check what else your recipe requires, since the tomatoes alone are not the finished dinner.

When does a smaller tin make sense?

Choose a smaller tin when the recipe needs less tomato and you would not use the remainder of a 400g tin. Tesco lists a 227g chopped-tomato tin, but check the recipe quantity before substituting it for a standard-sized one.

How should I store tomatoes left after opening a tin?

Follow the instructions on the specific pack, including its container, refrigeration and timeframe directions. For example, Marks & Spencer says to move its opened Chopped Italian Tomatoes to a non-metallic container, refrigerate them and eat them within three days.

What if I need to avoid a particular ingredient?

Read the ingredients and allergen information on the actual tin you intend to use. Product formulations differ, so a brand name or another variant’s ingredient list is not a substitute for that pack’s label.
