Cooks using milk in roast sides
If you want milk in mash or another side without choosing a higher-fat milk, skimmed milk is an option. NHS guidance describes it as a lower-fat milk choice for older children and adults.
Who is this choice for?
Households using only a little milk
If Sunday lunch calls for just a small amount, check whether you will use the rest in time. The reviewed Sainsbury’s chilled milk states three days after opening; Arla Cravendale and the reviewed Waitrose filtered milk state seven days.
Buyers concerned about a light-tasting mash
Arla positions its protein-enriched B.O.B skimmed milk as tasting like semi-skimmed milk. That may make it worth considering if taste is decisive, but the claim does not establish how it will taste in your recipe.
What should you check before buying?
Start with the amount your recipe needs, then compare the exact pack’s opened-life and the type of milk you want to cook with.
| Priority | What to check | Your needs |
|---|---|---|
| Milk choice | Check the milk type and nutrition panel on the pack. NHS guidance identifies skimmed milk as a lower-fat choice for older children and adults. | I want milk for mash or a sauce, but I am not choosing a higher-fat milk for that part of the meal. |
| Taste | Separate a brand’s taste claim from a tested result. Arla says its protein-enriched B.O.B skimmed milk tastes like semi-skimmed milk and can be used in cooking. | A light-tasting mash might not be what I want, so I would rather try a formulation aimed at a fuller taste than assume all skimmed milks taste alike. |
| Pack and storage | Match the pack size to planned use and read its opened-life. The reviewed Sainsbury’s chilled milk states three days after opening; Arla Cravendale and the reviewed Waitrose filtered milk state seven days. Follow each pack’s refrigeration instructions. | There may be milk left after Sunday lunch. I need a pack I can use within its own storage instructions. |
| Cupboard backup | Check preparation and storage after mixing. Sainsbury’s skimmed milk powder specifies 20g powder mixed with 200ml cold water; once mixed, it must be refrigerated and used within two days. | If I only need milk for occasional cooking, I may prefer to prepare the amount required rather than open a fresh bottle. |
| Dates and diners | Read the date mark, storage instructions and allergen declaration. GOV.UK distinguishes safety-related use-by dates from quality-related best-before dates. NHS guidance distinguishes cooking with skimmed milk for children over 12 months from giving it as a main drink to children under five. | Before serving a family roast, I need to check who can have milk and whether the pack can still be used as directed. |
What can catch you out?

Assuming skimmed milk guarantees a rich mash
The milk is only one part of the recipe; butter, cream and the cooking method also affect the result. Arla’s semi-skimmed-like taste description for B.O.B is its own claim, not a comparison of finished mash.
If taste is the deciding factor, try the milk in your usual recipe before relying on it for a larger meal.
-
Opening more milk than the meal needs
Opened-life varies by product: the reviewed Sainsbury’s chilled bottle states three days, while the reviewed Cravendale and Waitrose filtered bottles state seven days.
Check the recipe quantity and the exact pack’s instructions before choosing its size or format.
Milk left beyond the pack’s stated opened-life may have to be discarded.
-
Treating date marks as interchangeable
GOV.UK explains that use-by dates relate to food safety, whereas best-before dates relate to quality. Storage instructions still matter after opening.
Read both the date mark and refrigeration directions; do not use smell alone to decide whether food past a use-by date is safe.
-
Overlooking who will eat the roast
Skimmed cow’s milk contains milk, which matters for diners with a milk allergy. NHS guidance also says skimmed milk may be used in cooking for children over 12 months but should not be their main drink when they are under five.
Check the pack’s allergen information and consider each diner’s needs before adding milk to a shared dish.
Relevant brands and ranges
These references describe particular products and ranges, not how every milk from each brand will taste or how long every pack will keep.
Cravendale
Arla’s filtered skimmed milk is an option for planning to use an opened bottle over several days.
- Arla states that its 2L bottle keeps for up to three weeks unopened and seven days after opening when stored as directed.
- Those timings apply to this product; filtering does not establish a preferred taste.
Arla B.O.B
A protein-enriched skimmed milk aimed at buyers interested in the brand’s fuller-taste proposition.
- Arla lists 4.6g protein per 100g for its 2L skimmed milk and says it can be used in cooking.
- Arla’s claim that it tastes like semi-skimmed milk is not an independent sensory comparison.
Tesco
Tesco’s skimmed-milk range includes different formats for different storage and cooking plans.
- Tesco Groceries listed standard chilled, filtered and UHT skimmed milk, alongside branded products, in its skimmed-milk results.
- Check the chosen product’s own pack size, dates and storage directions rather than applying one format’s instructions to another.
Sainsbury’s
Its reviewed products offer a choice between ready-to-pour chilled skimmed milk and milk powder for occasional cooking.
- The reviewed 2.272L chilled milk is pasteurised skimmed milk and states three days after opening.
- The powder needs mixing; Sainsbury’s says to refrigerate it after preparation and use it within two days.
Waitrose
Waitrose describes its reviewed 2L skimmed milk as British, free-range and filtered.
- The retailer states up to one month unopened and seven days after opening, with refrigeration as directed.
- These are claims for the specified product; check the current pack and local availability before planning around it.
M&S
Its reviewed 568ml skimmed milk is a smaller chilled-bottle reference for a modest recipe quantity.
- M&S lists 0.3g fat per 100g and storage at 0°C to 5°C for this product.
- The retailer advises that it is best consumed within three days after opening.
Joybuy skimmed milk options
These Morrisons UHT skimmed-milk options suit a plan to keep milk for a future roast and use it in cooking. Choose between a single 1-litre carton and a six-pack according to how much you expect to use; neither listing establishes a particular level of mildness in the finished dish.

Morrisons British UHT Skimmed Milk, 1 litre × 6
The six-pack is worth considering if you expect to use more than one carton across future meals, rather than opening them all for one roast. The listing says to refrigerate a carton after opening and use it within three days. Check the carton’s allergen and child-use warnings before serving.

Morrisons British UHT Skimmed Milk, 1 litre
The single carton avoids committing to a six-pack when you need milk for one roast or a few other recipes. The listing says to refrigerate it after opening and use it within three days. Check the carton’s allergen and child-use warnings before serving.
Frequently asked questions
Can I use skimmed milk in mash for a Sunday roast?
Yes, if skimmed milk suits the result you want from your recipe. It will not itself supply the richness associated with adding higher-fat milk, butter or cream.
Which skimmed milk suits a roast I cook only once a week?
Consider how much milk you will use after opening. Arla Cravendale and the reviewed Waitrose filtered milk each state seven days after opening, while the reviewed Sainsbury’s standard chilled milk states three days; follow the exact pack’s dates and storage instructions.
Will Arla B.O.B make mash taste creamier?
That cannot be assumed from its formulation alone. Arla says its protein-enriched skimmed milk tastes like semi-skimmed milk and can be used in cooking, but this is the brand’s taste claim, not a comparison of mash made with different milks.
Can young children have skimmed milk in a roast dish?
NHS guidance says skimmed or 1% milk may be used in cooking for children over 12 months, but should not be given as the main drink to children under five. Check milk allergy and the needs of everyone eating the dish.
How should I store opened skimmed milk?
Follow the exact pack’s refrigeration and opened-life instructions. GOV.UK advises keeping food at 5°C or below if its after-opening instructions require refrigeration, and distinguishes safety-related use-by dates from quality-related best-before dates.
