What matters when choosing
Start with the number of slices you normally cook and the flat space they need. Then decide whether you need a separate appliance at all, or whether oven-style functions or independently controlled zones would earn their worktop space.
Basket air fryer
Choose it when: You regularly cook one or two portions and the usable basket or rack fits your slices.
Trade-off: A capacity stated in litres does not tell you how much flat space the slices have.
Countertop oven
Choose it when: A tray-style format and functions such as baking and grilling matter beyond this small batch.
Trade-off: Check whether the appliance's footprint is justified by how often you will use those functions.
Existing full-size oven
Choose it when: You are filling a larger tray or cooking aubergine alongside a larger meal.
Trade-off: Energy Saving Trust says an air fryer is generally cheaper to run for the same small meal, so occasional batches alone may not justify buying another appliance.

What to check |
Who this matters to |
| Small-meal energy use |
Consider how often you cook one or two portions rather than filling a full oven tray. |
I usually make only a few slices and would rather not heat the full-size oven for that meal. Around 42% of consumers put small-meal energy use first. |
| Slice layout and versatility |
Compare usable basket, rack or tray dimensions with your normal slice count; check the cooking functions you would use. |
I need the slices to fit in a practical arrangement and want the appliance to handle other oven-style cooking too. For around 33% of consumers, that layout and versatility are the primary concern. |
| Worktop space and mixed meals |
Check the appliance footprint, specified clearances and whether separate zones have independent controls. |
Aubergine is often just one part of my meal, but worktop width is limited. Keeping space for both foods is the main priority for around 25% of consumers. |
Joybuy products for these cooking formats
These air fryers and a countertop air-fryer oven offer different ways to cook a small batch of aubergine slices. Compare their usable cooking space and worktop footprint with your routine; the larger and multi-zone options make more sense if you also cook other foods or bigger batches.

Common questions
Do I need an air fryer for a few aubergine slices?
No: your existing oven remains an option, particularly when you are cooking other food with the slices. Energy Saving Trust says an air fryer is generally cheaper to run for the same small meal, while a full electric oven is better suited to batch cooking or larger groups; consider how often you would use a separate appliance.
Which dimensions matter for aubergine slices?
Check the usable flat area of the basket, rack or tray against the number of slices you normally cook. A capacity stated in litres does not show whether they will fit in your preferred arrangement, so ask for internal dimensions before choosing between formats.
Can I cook aubergine and another food at different settings?
Yes, if the appliance has independently controlled cooking zones. The Joybuy listing for Ninja SL300UK describes two drawers with separate controls and a Sync feature for coordinating finish times; check the controls on the particular model you intend to buy.
How should I power a countertop oven or air fryer safely?
Follow the model's instructions for electrical supply and placement, and do not use a damaged plug or cable. Scottish Fire and Rescue Service also advises against overloading sockets; check the manufacturer's clearance requirements before positioning the appliance.
