Choose the cooking layout before comparing stated litre capacities: a removable-divider model gives you one continuous area for a squash batch and separate zones for other meals. A large single basket suits cooks who mainly roast one food, while fixed dual drawers suit squash alongside another dish but divide the available space. Whichever layout you choose, check how loosely your usual portion will fit rather than assuming total capacity tells you how many wedges can roast at once.
Who is this for?
Weekly meal-prep cooks
If you roast squash for several meals, prioritise a basket or continuous zone that holds your usual portion without tight packing. Its usable shape matters more to this task than a longer list of cooking programmes; Tower Housewares advises leaving food loosely packed.
Mixed-meal batch cooks
If squash often cooks alongside another food needing different settings, separate zones may be useful. Check that the drawer reserved for squash still holds the portion you intend to make.
Small-kitchen batch cooks
If worktop space and cleaning effort affect whether you will use the appliance regularly, compare its external dimensions, basket shape and cleaning instructions before choosing by total litres.
What matters when choosing?
Start with whether your usual cooking session needs one open area for squash or separate areas for two foods. Then compare usable basket dimensions and the space the appliance needs on your worktop.
Removable-divider basket
Choose it when: you alternate between a large squash batch and meals that need two cooking zones.
Bear in mind: its stated total capacity does not tell you how many wedges fit loosely in the continuous area.
Large single basket
Choose it when: roasting one food at a time is your main use and you do not need separate programmes.
Bear in mind: cooking another food at a different setting calls for a separate cycle.
Fixed dual drawers
Choose them when: squash regularly shares a meal with another food needing its own settings.
Bear in mind: the capacity is split between drawers, so a large squash portion may take more than one batch.

What to check |
Who this matters to |
| Room for loose wedges |
Check the usable basket footprint and the maker’s loading guidance, not just total litres. |
I want to roast my usual squash portion without squeezing the wedges together or planning extra cycles. For around 50% of consumers, fitting a loose batch is the primary concern. |
| Two-food flexibility |
Check whether zones have separate settings and whether a divider can be removed. |
When squash accompanies another dish, I need to manage their cooking separately. Being able to do that comes first for around 30% of consumers. |
| Worktop and upkeep |
Compare external dimensions, cleaning instructions and the space needed around the appliance. |
I need an appliance I can accommodate and clean between batch-cooking sessions, even if that means making smaller batches. Around 20% of consumers put manageable ownership first. |
Pitfalls to avoid
-
Equating litres with a loose layer of squash
Drawers with similar stated capacities can have different shapes, and two fixed drawers do not provide one continuous cooking area. Tower Housewares advises against packing food tightly.
Compare internal dimensions with the amount and thickness of the wedges you normally prepare, leaving room around the food.
-
Choosing fixed dual drawers for one large batch
Separate drawers are useful for foods needing different settings, but the split can limit the space available for one uninterrupted squash batch.
If squash is usually the only food you are roasting, compare a large single basket or removable-divider design before settling on fixed drawers.
-
Blocking airflow with foil or a liner
Instant Pot’s Vortex 5L manual warns against covering the basket, cooking tray or other appliance parts with foil because of overheating risk. Instructions for accessories can differ by model.
Follow your exact model’s manual, keep airflow paths clear and ensure any permitted liner cannot contact the heating element.
-
Cooking ahead without a storage plan
Batch cooking does not end when the squash leaves the basket. GOV.UK advises refrigerating leftovers within two hours and eating them within 48 hours or freezing them.
Divide the squash into portions so it cools promptly, then refrigerate or freeze it within that window. Reheat a portion until it is steaming hot throughout.
If you cannot eat the refrigerated portions in time or freeze them, food may have to be discarded.
Brands to consider for these layouts
Ninja
Ninja offers both a removable-divider layout and fixed dual zones in the models relevant here.
- Joybuy lists the AF500UK with a divider that can be removed to make one 10.4L MegaZone; Ninja Kitchen UK lists the AF400UK with two separate zones and a stated 9.5L total capacity.
- The AF400UK’s fixed division may be less convenient for one continuous batch. Neither stated total capacity establishes how many squash wedges fit loosely.
Instant Pot
The Vortex range includes convertible and fixed two-basket formats for different cooking routines.
- Instant Pot UK describes its VersaZone format as usable as one basket or divided into two; its Vortex Dual 8L has two 4L baskets.
- Check the dimensions and loading guidance for the particular model and variant, especially if a large squash batch matters more than separate foods.
Tefal
The Easy Fry Mega EY855D40 is a single-basket option for cooks who mainly want one cooking area.
- Tefal UK Shop states a 7.5L capacity, manual temperature control from 80°C to 200°C and a timer of up to 60 minutes.
- A single basket does not provide independently controlled zones. Check its internal and external dimensions against your portion and worktop space.
Tower
Tower’s loading advice is relevant when assessing any air fryer for wedges.
- Tower Housewares advises avoiding tightly packed food, a useful reminder when comparing basket layouts.
- Check the capacity and layout of the particular Tower model rather than assuming the same features apply across its range.

Common questions
How large should an air fryer be for batch-roasted squash wedges?
Choose by usable basket space, not litres alone. Decide whether you need one continuous area or separate drawers, then compare the internal footprint with your usual amount of squash and leave room between wedges; Tower Housewares advises against tight packing.
Can I use foil or a liner for squash wedges?
Only use an accessory in the way your exact air fryer’s manual permits. Instant Pot’s Vortex 5L manual warns against covering the basket, cooking tray or appliance parts with foil because of overheating risk; keep airflow clear and any permitted liner away from the heating element.
How should I store squash cooked ahead for meals?
Divide the cooked squash into smaller portions so it cools promptly, then refrigerate it within two hours. GOV.UK advises eating refrigerated leftovers within 48 hours or freezing them; reheat a portion until it is steaming hot throughout.
Should I use an air fryer’s preset for squash wedges?
Use the instructions and recipe guidance for your chosen model as a starting point rather than assuming a preset will suit every batch. Check the wedges during cooking and adjust how much you load if they are too tightly packed.
