Who this choice suits

Small-portion cooks with little worktop space

If you make gratin occasionally for one or two people, a compact basket model may be worth considering. Measure your dish, including its handles, before relying on the capacity figure. Instant Pot UK lists its Vortex Compact 5L at 34.8 × 26.7 × 27.9 cm externally; those measurements do not establish the space inside its basket.

Regular gratin and tray-bake cooks

If you often cook in a baking dish, an oven-style air fryer offers a rack-based layout to investigate. The Instant Pot Vortex Plus 13L Air Fryer Oven and Tefal Easy Fry Multifunction Oven FW556DG0 list Bake and multi-level trays or racks. Check dish fit and the space each appliance needs on your worktop.

Cooks who want one appliance for several meals

If gratin is only one of the meals you plan to make, compare the exact model’s cooking programmes and cleaning arrangements alongside dish fit. The Instant Pot models considered here offer different combinations of baking, reheating and other functions; the programme list depends on the model.

What to check before buying

Basket air fryer

Consider it when: You make smaller gratins and can confirm that your dish fits the usable basket with the required clearance.

Trade-off: A deep basket may be awkward for a broad, shallow dish, even when the stated capacity looks sufficient.

Oven-style air fryer

Consider it when: You regularly bake in dishes and want a model with Bake and a rack-based cooking layout.

Trade-off: Allow for its external size as well as ventilation space; racks do not remove the need to check your dish against the usable chamber dimensions.

ConcernWhat to checkWho this matters to
Gratin dish fit Measure the oven-safe dish including handles; check usable basket or rack dimensions and the model’s required airflow clearance. I need my usual gratin dish to sit safely inside the appliance without blocking airflow. Around 42% of consumers put dish fit first.
Worktop space Compare external width, depth and height with the intended position, allowing the ventilation space specified in the instructions. In my small kitchen, the appliance has to fit where I can use it safely, not merely where I can store it. Worktop space comes first for around 33% of consumers.
Everyday use Check the exact model’s programmes and included accessories against the meals you cook beyond gratin. If this will be my appliance for several meals, I want its other functions to suit my routine as well. Around 25% of consumers prioritise that versatility.

Mistakes to avoid

  • Choosing by litre capacity alone

    Capacity does not tell you the usable width or depth available for a shallow gratin dish.

    Measure the dish including its handles, then check the model’s internal dimensions and required clearance in its manual or with the manufacturer.

  • Assuming a basket works like an oven rack

    A basket and a rack-based oven have different layouts. Neither format guarantees that your particular dish will fit.

    For regular gratins, compare usable rack and chamber measurements; for occasional small portions, compare the basket’s usable measurements.

  • Letting a liner obstruct airflow

    Loose paper, foil or an unsuitable accessory can interfere with the arrangement specified for the appliance.

    Follow the exact model’s instructions for dishes and liners, and keep any permitted liner secure.

  • Overlooking model-specific recalls

    A product-safety action concerns the models identified in its notice, rather than every appliance from the same brand.

    Search the Office for Product Safety and Standards recall service using the exact brand and model, particularly when buying second-hand, and follow any instructions that apply to your appliance.

Frequently asked questions

Is a 5L air fryer large enough for potato gratin?

It can be, but 5L does not establish whether your oven-safe dish fits. Measure the dish including handles, then check the model’s usable basket dimensions and required clearance.

Should I choose a basket air fryer or an air-fryer oven for gratin?

A basket model is worth considering for small, occasional gratins when the dish fits safely. For regular dish-based baking, an oven-style model with Bake and racks offers a layout to consider, provided you can accommodate its external size and confirm internal dish clearance.

Can I use baking paper or foil around a gratin dish?

Use them only in an arrangement permitted by the exact appliance instructions. Check that any permitted liner stays secure and does not obstruct airflow or reach a heating element.

How should I position an air fryer in a small kitchen?

Place it on a stable surface with the clearance specified for the model. Cheshire Fire and Rescue Service advises leaving sufficient space around an air fryer to avoid overheating and not plugging it into an extension lead.

How can I check whether an air fryer has been recalled?

Search the Office for Product Safety and Standards product recalls and alerts service using the exact brand and model number. If a notice identifies your model, follow its corrective-action instructions rather than assuming the notice applies to every product from that brand.
