Who is this for?

Large-pan batch cooks

If you caramelise onions in a wide sauté pan or cook other components at the same time, usable zone space matters more to you than a compact hob footprint.

Low-heat control seekers

If your main worry is onions catching during a long cook, you may value readily adjustable controls or a model-specific temperature-assistance feature. Pan choice and stirring still matter.

Kitchen-fit upgraders

If you are replacing a hob, the new appliance must suit your worktop opening, electrical connection and onion pan. Those checks can narrow the choice before extra cooking features do.

What matters when choosing?

60 cm ring-zone induction

Consider it when: your pan base fits one zone and retaining a standard-width hob is the priority.

Trade-off: a conventional ring-zone layout does not join zones for an unusually wide pan.

Wider bridge-zone induction

Consider it when: a wide pan needs joined cooking zones, or you want room to use other pans alongside it.

Trade-off: a wider built-in model may require worktop changes; AEG UK specifies a 750 × 490 mm cut-out and hardwired connection for its IKX84443CB.

Flex-zone induction with a frying sensor

Consider it when: flexible pan placement and temperature assistance are priorities during multi-pan cooking.

Trade-off: NEFF UK describes these features on its T68FUV4L0, but they do not establish how it will caramelise onions in your pan or remove the need to stir.

Concern What to check Who this matters to
Avoiding scorching Look for controls you can adjust readily during a long cook. If you want temperature assistance, confirm that the exact model has a frying sensor. If onions tend to catch while I am managing a large batch, I want to adjust the heat without relying on boost power; around 40% of consumers put avoiding scorching first.
Usable pan area Measure the pan base and check the zone layout. For a wide or rectangular base, confirm whether the model can join zones or offers a suitable flex area. When my onion pan takes up substantial space, I need a layout that also accommodates the other pans I use; roughly 30% of consumers prioritise large-pan or multi-pan space.
Kitchen and pan fit Compare the specified cut-out and connection with your kitchen, then check that the pan has a suitable induction-compatible base. Before replacing my hob, I need to know that it can be installed and will work with my main pan; about 30% of consumers put installation and cookware fit first.

Buying pitfalls

  • Assuming a larger glass surface fits any pan

    The usable cooking area depends on the zones and the pan base, not just the overall hob width. Induction also requires suitable cookware.

    Measure the base rather than the rim, check whether a magnet is attracted to it and compare it with the exact model’s zone guidance. For a particularly wide pan, verify that the model has the bridge, combi or flex feature you need.

    You may need a different pan if your existing one is unsuitable for the chosen induction hob.

  • Choosing a wider hob before checking the opening

    A wider hob cannot be assumed to fit a worktop opening made for a 60 cm model. AEG UK specifies a 750 × 490 mm cut-out and hardwired connection for the IKX84443CB.

    Compare the appliance and cut-out dimensions with your kitchen, check the connection instructions for the exact model and seek installation advice appropriate to where it will be fitted.

    Changing the worktop opening or arranging electrical installation may add work to the replacement.

  • Leaving boost power on for the long cook

    Boost is a rapid-heating feature, not a substitute for controlling heat as onions cook over time.

    Use rapid heating only when it suits the pan and ingredients, then move to a controllable setting and stir regularly. If temperature assistance matters to you, check for it on the exact model.

  • Scrubbing residue with abrasive materials

    AEG UK warns that abrasive cleaners and scouring pads can scratch an induction hob’s surface.

    Allow the zones to cool and follow the model’s cleaning instructions, using a suitable hob-cleaning method and scraper where appropriate.

Brands to consider for these hob layouts

AEG

AEG UK’s 80 cm IKX84443CB illustrates a built-in bridge-zone option for a wide pan.

  • Its Bridge function joins two zones; the cited four-zone model also has a minute minder and pause function.
  • The IKX84443CB has no assisted cooking sensor, requires a 750 × 490 mm cut-out and is hardwired only.

NEFF

NEFF UK’s 80 cm T68FUV4L0 illustrates a five-zone model for buyers interested in flexible pan placement and temperature assistance.

  • NEFF states that this model has a flex zone that detects cookware placement and an Extended Frying Sensor that monitors the selected temperature.
  • Those model-specific features are not independent evidence of caramelising results; check its installation requirements and whether they suit your cooking routine.

Bosch

Bosch UK’s 60 cm PIE631BB5E illustrates a conventional four-ring-zone layout; its PWP611BB5B is a separate 60 cm CombiZone option.

  • Bosch lists PowerBoost, QuickStart and restart functions for the PIE631BB5E, and a CombiZone for the PWP611BB5B.
  • The PIE631BB5E does not join zones for a wide pan, so check that your pan base fits one of its ring zones.

Joybuy product choices for batch cooking

These induction hobs cover two relevant approaches: a 77 cm model with a bridge zone for wider-pan use and a 60 cm ring-zone model for a pan that fits a single zone. Check the pan and installation requirements of whichever layout you choose.

Belling IHL773 BLK induction hob

Belling IHL773 BLK 77 cm bridge-zone induction hob

Consider this model if a wider pan or cooking alongside other pans makes a bridge zone useful. Its stated configuration has four cooking zones, a flexible bridge, touch controls and boost mode. Check the zone dimensions against your pan base and confirm the connection and installation instructions before ordering.

Bosch PIE631BB5E Series 4 induction hob

Bosch PIE631BB5E Series 4 60 cm induction hob

Consider this conventional four-zone layout if your onion pan fits a single ring zone and a 60 cm hob suits your kitchen. Bosch UK lists PowerBoost for this model, but controllable heat matters more during the long cooking stage. The listed variant is hardwired; check the cut-out and zone dimensions and arrange installation advice before purchase.

Frequently asked questions

Will my existing onion pan work on an induction hob?

It can work if its base is attracted by a magnet and is flat and appropriately sized for the intended zone. NEFF UK advises that cookware quality affects heating results, so compare your pan base with the guidance for the exact hob.

Do I need a bridge or flex zone to caramelise onions?

No: a standard ring zone can be sufficient when the pan base fits it. A bridge or flex zone is worth considering for a wider or unusually shaped pan, or when you need more flexible space for other batch-cooking pans; AEG UK describes joined zones on the IKX84443CB, while NEFF UK describes flexible cookware placement on the T68FUV4L0.

Will PowerBoost improve the long caramelising stage?

PowerBoost is intended for faster initial heating, not for maintaining the gentle, controlled cook needed over time. Bosch UK describes it as a faster-heating feature on the PIE631BB5E; during caramelising, adjust the heat to suit the pan and stir the onions regularly.

How should I clean an induction hob after cooking onions?

Allow the cooking zones to cool, then follow your model’s instructions for removing residue with a suitable scraper or non-abrasive cleaning method. AEG UK advises against abrasive cleaners and scouring pads because they can scratch the surface.
