Regular onion batch-cookers
If you cook onions often or in larger batches, you need to manage the change to low heat and stay nearby to stir. Tesco Real Food’s onion recipe calls for a low-heat stage with regular stirring after the initial cook.
Who this choice affects
Shared-kitchen safety planners
When several people use the hob, control locks and hot-surface warnings deserve attention alongside a rule that someone stays with the cooking. Buckinghamshire Fire & Rescue Service advises turning off the heat if you need to leave the room.
Cookware- or installation-constrained households
Existing pans, the worktop opening and the available electrical connection may determine which hob is practical. Bosch UK says induction requires magnetic cookware; connection arrangements also differ between individual models.
What to check before buying
Induction
Choose it when: Your onion pan has a magnetic base and you want prompt heat changes between the initial cook and the low-heat stage.
Trade-off: Non-magnetic pans will not work; a plug-in model and a hardwired model also call for different electrical checks.
Radiant ceramic
Choose it when: Keeping a mixture of existing pans, including non-magnetic ones, is the deciding need.
Trade-off: NEFF Home UK warns that a ceramic cooking surface remains hot to touch after use, so everyone sharing it needs to recognise when a zone is still hot.
| Concern | What to check | Who this matters to |
|---|---|---|
| Low-heat control | Try the controls in the product instructions and check that your onion pan works with induction if choosing it. | I want to turn the heat down after the onions begin cooking, then adjust it while stirring through the low-heat stage. Around 33% of consumers put this control need first. |
| Shared-use safety | Check for a control lock and residual-heat indication; agree who stays with the pan while it cooks. | If housemates use the hob between cooks, I want to reduce accidental control changes and make hot zones easier to recognise. This is the first concern for around 27% of consumers. |
| Cookware and installation | Check the pan base, the required worktop cut-out and the exact model’s electrical instructions. | I need a hob that works with the pans and kitchen I already have, rather than discovering a fit problem after ordering. Around 27% of consumers prioritise this need. |
| Shared clean-up | Check the control layout and agree who cleans spills once the surface is cool. | When several people cook in the same space, I want spills dealt with without anyone touching a hot zone. For around 13% of consumers, straightforward upkeep comes first. |
Mistakes to avoid
-
Assuming every frying pan works on induction
Induction needs a magnetic pan base, according to Bosch UK. A pan’s material name alone is not a dependable compatibility check.
Check the manufacturer’s induction marking or whether a magnet adheres to the base of the pan you use for onions.
Changing to induction may also mean obtaining compatible cookware if the household’s existing pans do not work.
-
Measuring only the visible width of a built-in hob
Hobs described as 60 cm models can have different worktop and connection requirements. For example, Electrolux UK specifies a 560 × 490 mm cut-out and hardwired-only connection for the LIB60420C.
Measure the opening and check the chosen model’s clearance, ventilation and electrical instructions before ordering. In a rented or managed kitchen, confirm permission before arranging a replacement.
A mismatched opening or electrical arrangement can mean worktop changes or electrical installation work.
-
Treating a switched-off ceramic zone as cool
NEFF Home UK warns that ceramic surfaces stay hot to touch after use. A control lock does not remove that heat.
Look for residual-heat indication and agree that nobody places items on, touches or cleans a zone until it has cooled.
Relevant brands to consider
Bosch
Its PUG61RAA5B induction and PKE61RAA8B ceramic models illustrate the cookware and hot-surface choices within one brand’s hob range.
- Bosch UK lists the PUG61RAA5B as a four-zone Plug & Play induction hob with PowerBoost and ChildLock.
- The induction model needs magnetic cookware; the ceramic model’s cooking surface remains hot after use.
AEG
The TN64IA04FB is an induction option for households considering individual-zone touch controls and a pause function.
- AEG UK specifies four zones, a UK moulded plug, PowerBoost, pause and a child lock for this model.
- Check magnetic pan compatibility and the specified 560 × 490 mm cut-out against the kitchen.
Electrolux
The LIB60420C is a four-zone induction model for a kitchen suited to its built-in dimensions and hardwired connection.
- Electrolux UK specifies child lock, residual-heat indicators and automatic switch-off for this model.
- Its hardwired-only connection needs to suit the kitchen’s electrical arrangement.
NEFF
Its ceramic range is relevant when keeping existing non-magnetic cookware is a priority.
- NEFF Home UK says models in its ceramic range can offer up to 17 power settings and residual-heat indicators; check the features of the particular model.
- NEFF warns that the ceramic surface becomes hot to touch after use.

Frequently asked questions
Is induction or ceramic more suitable for caramelising onions?
Induction suits a magnetic frying pan when prompt heat changes matter; ceramic suits a household that needs to keep non-magnetic pans. Tesco Real Food’s onion recipe moves to low heat and calls for regular stirring, so neither hob type removes the need to stay with the pan. A ceramic surface also remains hot after switch-off.
Will my frying pan work on an induction hob?
It will work if its base is magnetic and the pan is suitable for induction. Bosch UK advises using magnetic cookware for induction; check the pan maker’s marking or whether a magnet adheres to its base.
Does a plug-in hob avoid installation checks?
No. Even a plug-in model must suit the worktop opening, ventilation requirements and intended electrical supply. Check the exact hob’s installation instructions and seek qualified electrical advice if the kitchen’s supply is uncertain.
What should we do while onions cook in a shared kitchen?
Someone should stay with the cooking and turn off the heat if they need to leave the room. Buckinghamshire Fire & Rescue Service also advises keeping flammable items away from the hob; agree who is responsible for the pan and wait for hot zones to cool before cleaning.
