Induction Hobs for Red Lentil Soup: Small Worktop Fit

Who each format suits

One-pot cooks with almost no spare worktop

If soup is usually the only dish on the hob, a portable single zone can be put away afterwards. Check where the appliance will sit during cooking as well as where you will store it.

Cooks who want to control the simmer

After bringing the soup to a boil, you want a way to reduce the heat. Look for manual low-power settings or a slow-cook or stew function, alongside a suitable pan.

Small-kitchen cooks who regularly use two pans

A portable dual-zone hob can accommodate another component alongside the soup, provided its larger footprint fits your available worktop.

What matters when choosing

For red lentil soup with limited worktop space, check the hob’s in-use and storage dimensions first, then its heat controls and fit with your saucepan.

Concern	What to check	Who this matters to
Worktop and storage fit	Measure the clear space for cooking and the place where the hob will be stored; thickness alone does not describe its full footprint.	I have little room to leave a hob out after making soup, so it needs a place to go between meals. Around 36% of consumers put worktop and storage fit first.
Simmer control	Check the manual low-power settings and whether the hob offers slow-cook or stew controls.	Once the lentils reach a boil, I want to lower the heat rather than rely on a boil preset. For around 29% of consumers, simmer control is the main concern.
Saucepan compatibility	Check that the base is magnetic and that its diameter falls within the chosen hob’s stated range.	I want to keep using my soup pan, but its labelled size may describe the rim rather than the base. Roughly 21% of consumers place pan compatibility first.
Second-pan capacity	Measure the space for a dual-zone hob and check that both pans meet its cookware requirements.	If I regularly prepare another component alongside soup, one cooking zone will not do both jobs at once. Around 14% of consumers prioritise second-pan capacity.

Mistakes to avoid

Assuming any metal saucepan will work

Induction cookware needs a suitable magnetic base, and a saucepan’s advertised diameter may refer to its rim. The base also needs to meet the chosen hob’s size requirements.

Judge suggests testing the external base with a magnet as a preliminary check. Measure that base and compare it with the exact hob model’s stated pan range before buying.
Choosing two zones without measuring the worktop

A second zone is useful when two pans must cook together, but a dual-zone appliance occupies more of the working surface than a single-zone plate.

Decide whether the second pan is a regular part of the meal, then measure the space available for the hob during use.
Relying on a boil programme for the whole soup recipe

A preset boiling cycle may not suit every pan, liquid quantity or recipe. Soup also needs heat reduced after the initial boil.

Check the programme conditions in the chosen model’s instructions, and use adjustable controls to manage the cooking stage that follows.
Overlooking the identity of the appliance and seller

A 2025 Office for Product Safety and Standards report identified a particular induction cooker with a serious fire risk linked to its plug fuse; that finding does not describe all portable hobs.

Buy from a traceable seller, inspect the appliance and plug on arrival, and consult the UK product recalls and alerts service if the model raises a safety concern.

Brands to consider

These brands provide useful points of reference for comparing portable hob formats and cookware requirements; check the specifications of the particular model you are considering.

Tefal

Its Everyday IH201840 and Everyday Slim IH210840 are portable single-zone options for one-pan cooking.

Tefal UK lists soup and stew functions for the IH201840; the IH210840 has a stated thickness of 45 mm and includes slow-cook and stew functions.
Both models cook on one zone, so neither accommodates a second pan at the same time.

VonShef

Its portable range includes a 2000 W single-zone hob and a 2800 W dual-zone hob.

VonShef lists power settings from 200 W to 2000 W for the single hob; its dual model has two plates rated at up to 1400 W each.
The dual-zone format needs more worktop space, so measure before choosing it for a small kitchen.

Judge

Judge’s cookware guidance is useful when assessing an existing soup saucepan for induction use.

Judge recommends a magnet check on the pan’s external base and explains that a saucepan’s quoted size may be measured at the rim.
A cookware check does not replace the selected hob model’s own pan-size requirements.

Common questions

Will my existing saucepan work on a portable induction hob?

It may work if its base is magnetic and fits the chosen hob’s stated pan-size range. Judge recommends a magnet test on the external base as a preliminary check; measure the base rather than relying only on a rim diameter. Tefal UK states a compatible pan range of 12 cm to 26 cm for the IH201840 and IH210840.

Which controls matter for red lentil soup?

Look for a way to lower the heat after bringing the soup to a boil, such as manual low-power settings or a slow-cook or stew function. Tefal UK lists soup and stew programmes for the IH201840, while the IH210840 includes slow-cook and stew functions; check how the chosen model’s controls work with your pan and recipe.

Can someone with a pacemaker use a portable induction hob?

Do not assume an induction hob is suitable for someone with a pacemaker or similar medical device. Tefal’s induction-cooker instructions say people fitted with such devices should stay away while the cooker is connected to power and should consult a medical practitioner if unsure.

What safety checks are useful when buying a portable induction hob?

Choose a traceable seller and keep the appliance’s model identification so you can check relevant safety notices. The Office for Product Safety and Standards publishes UK product recalls and alerts; inspect the appliance and plug on arrival, and check its notices if a model raises concern.
