For one or two portions of onion soup on a tight worktop, start with a slow cooker below 3L and compare its external width and depth, not just its capacity. Consider a larger pot if leftovers matter more than the smallest footprint; either way, check lid clearance, pot care and where the plug will reach before buying.
If you usually make only a couple of portions, a small pot is worth considering—but it still has to fit where you will use it. The product information places slow cookers below 3L with small meals for one or two people; the Cookworks 1.5L model is listed at 21cm wide and 20.3cm deep.
If the next day’s lunch is part of the plan, capacity may matter more than finding the smallest appliance. The product information associates the 3–4.9L size range with everyday meals and leftovers, though the dimensions of the particular cooker still determine whether it fits.
If you want to prepare the soup earlier and keep cleanup manageable, look beyond litres. Check the exact model’s controls, removable-pot care instructions and any timer or keep-warm function rather than assuming those features come together.
Decide how many portions you normally make, then measure the available worktop area. Capacity, external dimensions and day-to-day handling need to work together.
| Concern | What to check | Who this matters to |
|---|---|---|
| Worktop fit | Compare the exact model’s width and depth with the space available, allowing room to lift the lid and reach the socket. | If I have one small spot for the cooker, I need to know the whole appliance will fit there, not merely that its pot holds less soup. Around 42% of consumers would put worktop fit first. |
| Portions and leftovers | Check the stated capacity and portion guidance against the amount you usually cook. The product information places sub-3L cookers with small meals for one or two, and 3–4.9L cookers with everyday meals and leftovers. | When I want another serving for tomorrow, the smallest pot could leave me making soup more often. Roughly 33% of consumers would make portion capacity their main concern. |
| Controls and cleanup | Check for the controls you will use, including keep-warm or a timer, and read the pot and lid care instructions. | If I prepare soup ahead of time, I want serving and washing up to remain manageable. About 25% of consumers would prioritise that day-to-day ease. |
Pot capacity cannot tell you whether the cooker, its lid and its lead will fit the intended spot. The Cookworks 1.5L example measures 21cm wide by 20.3cm deep, but other models need their own dimension checks.
Measure the available area and compare it with the exact model’s external dimensions, leaving space to remove the lid and access the socket.
The Cookworks 1.5L pot is not suitable for hob or oven use. A removable pot does not, by itself, let you brown onions in the same vessel before slow cooking.
If one-vessel browning matters, check the exact pot’s instructions and whether it is compatible with your hob.
The Cookworks 1.5L bowl is removable, but the product information lists the pot and lid as hand-wash only.
Read the care instructions for each component of the model you are considering.
A small kitchen can make water, hot surfaces and trailing leads harder to avoid. Electrical Safety First advises against using electrical equipment with wet hands, overloading sockets or leaving appliances on and unattended.
Choose a position away from the sink where possible, keep the socket accessible, inspect the lead and plug, and follow the cooker’s operating instructions.
The Cookworks 1.5L compact slow cooker is a reference point for one or two portions where worktop fit comes first.
Crockpot spans smaller and larger slow-cooker formats. The product information associates the brand’s 1.8–3.5L range with single meals or couples.
Morphy Richards has 3.5L and 6.5L slow-cooker options in the UK range considered here, making its models more relevant if extra portions take priority over the smallest pot.
These options are for cooks considering a 3.5L slow cooker or a 5L multi-cooker rather than choosing solely for the smallest pot. Compare each appliance with your available worktop and usual soup portions.

Consider this 3.5L cooker if you want more than the smallest one- or two-portion format and have room for it on the worktop.
The product name specifies three heat settings, a removable pot and cool-touch handles. Check the space needed to open the lid and the care instructions for the pot and lid.

Consider this larger multi-cooker if you want one appliance with slow-cook and soup options, and have room for a 5L pot.
Its product name identifies it as a 14-in-1 model and lists both slow cooking and soup making. Check its external dimensions, lid clearance and guidance on the amount of soup you plan to make.

Consider this 3.5L model if timed controls matter and you can accommodate its width on the worktop.
The product name specifies a removable aluminium pot, LED display, delay function and timer. If you want to brown onions in the pot, check your hob first: the stated hob-use guidance excludes induction.
Start by comparing models below 3L if you usually make one or two portions and worktop space is tight. The product information places that size range with small meals for one or two; the Cookworks 1.5L model is listed for the same portion range. Check the appliance’s external dimensions as well as its capacity.
A larger pot is worth considering if you regularly want soup left over and can fit the appliance. The product information associates 3–4.9L slow cookers with everyday meals and leftovers; compare the dimensions and follow the chosen model’s guidance for the quantity you intend to cook.
Only if that particular pot is approved for your hob. The Cookworks 1.5L pot is not suitable for hob use, while hob-searing is described for relevant Crockpot Sizzle & Stew models. Check both the exact model and your hob type before planning to brown onions in the pot.
Choose a stable position with room for the lid and an accessible socket, away from the sink where possible. Electrical Safety First advises against wet-hand operation, overloaded sockets and leaving electrical appliances on and unattended; also follow the instructions for your cooker.
