Solo cooks short on worktop space
If you usually make one or two portions, storage and washing-up may matter more than room for a large batch. The product information suggests its 3L Instant Pot Duo 3 Mini for one or two portions.
Who is this for?
Solo cooks planning leftovers
If you cook once for several meals, a larger bowl may be worth storing. Instant Pot describes its 3.8L Classic Mini as making up to four portions; the capacity still needs to suit your usual recipe.
Buyers replacing other cooking appliances
If soup is only one job for the cooker, extra modes may justify a larger appliance. The product information lists the 6L Ninja Foodi OP350UK for up to three or four people, making its size an important consideration for a one-person kitchen.
What matters when choosing?
Decide how many portions you normally want and where the cooker will live. Then weigh up washing-up and extra functions against the space they require.
| Concern | What to check | Who this matters to |
|---|---|---|
| Portions and storage | Compare suggested portions, working capacity and dimensions; check the manual’s liquid and fill limits. | I usually want just one bowl and need somewhere to put the cooker afterwards. Around 36% of consumers put portion fit and storage first. |
| Cooking and clean-up | Check the controls you would use for soup and which removable parts the maker says are dishwasher-safe. | On a regular soup night, I want straightforward controls and a pot I can clean without fuss. For around 29% of consumers, that routine convenience is the main concern. |
| Planned leftovers | Choose capacity for the number of servings you intend to make, not just the immediate meal. | I live alone but prefer to cook several portions at once for later meals. That need comes first for around 21% of consumers. |
| Other cooking modes | Identify the additional functions you would actually use and allow space for the appliance. | Soup is only one of the meals I want to make, so extra modes may earn their place in my kitchen. Around 14% of consumers prioritise those functions. |
Buying pitfalls
-
Treating a litre label as a serving guarantee
Capacity alone does not tell you whether a particular single-serving recipe meets the cooker’s operating requirements. The product information suggests the 3L Duo 3 Mini for one or two portions, while Instant Pot describes the 3.8L Classic Mini as making up to four.
Start with your usual serving count, then check working capacity, kitchen fit and the exact model’s recipe and fill guidance.
-
Filling lentil soup too high
Soup needs room in the pot during pressure cooking. The Instant Pot Duo manual limits normal filling to two-thirds of capacity and foods that expand to one-half.
Follow your model’s markings and instructions for expanding ingredients, minimum liquid and pressure release; do not fill a smaller pot to the rim to fit a larger recipe.
-
Choosing extra modes without allowing for the appliance
Air-frying and grilling may be useful if you will use them; the product information lists the Ninja Foodi OP350UK as a 6L appliance weighing 9.5kg. That is a different storage commitment from choosing a cooker chiefly for one bowl of soup.
Decide which modes will see regular use before accepting a larger cooker and its additional parts.
-
Using keep-warm in place of storing leftovers
Keeping soup warm is not the same task as cooling it for a later meal. GOV.UK guidance on cooking food calls for checking that food is thoroughly cooked before serving; its food-hygiene guidance for businesses says reheated food should be steaming hot throughout.
If you make extra soup, cool and refrigerate the leftovers promptly, then reheat them thoroughly rather than merely warming them.
Brands to consider for this use
Instant Pot
Its compact UK multicookers include a 3L Duo 3 Mini in the product information for one or two portions and a 3.8L Classic Mini that Instant Pot describes as making up to four portions.
- These two sizes offer a choice between an immediate small meal and deliberately making extra soup.
- Check the manual for the chosen model: portion descriptions do not establish the liquid and fill limits for every lentil recipe.
Tefal
The Turbo Cuisine CY756140 is a 4.8L electric pressure multicooker for someone considering soup alongside other meals. Tefal lists 10 automatic programmes.
- Its dial-led controls and range of programmes offer an alternative to the smaller formats.
- A 4.8L bowl takes more room than a 3L cooker when a single serving is the usual goal.
Ninja
The Foodi OP350UK combines pressure cooking with other modes, including air frying, for buyers who expect to use more than soup functions.
- The additional modes may be relevant when one appliance is intended to cover several cooking tasks.
- The product information lists this model at 6L and 9.5kg, so allow for its size and weight in a solo kitchen.

Frequently asked questions
What size pressure cooker should I consider for lentil soup for one?
A compact model is a practical starting point if you normally want one or two portions:the product information suggests the 3L Instant Pot Duo 3 Mini for that serving range. A smaller or larger cooker may also suit your recipe, but check its working capacity and model-specific liquid and fill requirements rather than relying on litres alone.
Can I make lentil soup in an electric pressure cooker without using the hob?
Yes, an electric pressure cooker provides its own pressure-cooking function, while the available additional modes depend on the model. Follow a recipe suited to your cooker and its instructions for liquid, cooking settings and pressure release.
How full can the cooker be when making lentil soup?
Follow the fill markings and instructions for your exact cooker, particularly for ingredients that expand. The Instant Pot Duo manual sets a normal maximum of two-thirds of capacity and a maximum of one-half for expanding foods; do not assume those markings or a recipe quantity transfer unchanged to another model.
What should I do with leftover lentil soup?
Cool and refrigerate soup intended for a later meal, then reheat it until steaming hot throughout rather than merely warm. GOV.UK food-hygiene guidance for businesses also advises reheating food only once; keep-warm is not a substitute for storing leftovers.
