Small-kitchen snack makers
If you usually make one or two portions, the usable tray area, controls and space needed around the oven matter more than a large stated capacity.
Who is this for?
Crispness-first home cooks
If you want thin slices to brown evenly, look closely at airflow, the supplied cooking surface and whether your portion can be spread in one layer. KitchenAid’s sweet potato chip recipe calls for an even, single layer.
Multifunction oven users
If chips are only one of several regular uses, bake, toast, grill and additional cooking levels may justify a larger countertop appliance.
What matters when choosing?
Check whether the cooking surface fits your usual batch before comparing cavity capacity. Then weigh the counter space, extra functions and cleaning routine you are willing to accommodate.
| Concern | What to check | Who this matters to |
|---|---|---|
| Crisp, even chips | Check for an air-fry or high-airflow convection setting and a mesh or perforated surface with room for one layer. | If crispness is my priority, I want the slices spread out rather than piled together. Around 33% of consumers would put this need first. |
| Counter space | Compare exterior dimensions, usable tray area and the clearance required by the model’s instructions, not litres alone. | With a small kitchen and snack-sized portions, I need the oven to fit where I can use it safely. About 27% of consumers would prioritise counter space. |
| Everyday versatility | Check the listed cooking functions, included racks and number of cooking levels against the other meals you plan to make. | If I will also bake, toast or grill regularly, I can make use of more than a chip-cooking setting. Roughly 20% of consumers would put multifunction use first. |
| Cleaning and setup | Check which accessories can be removed and how to clean them; follow the manual’s placement and hot-surface instructions. | When I cook with oil or seasoning, I want a manageable cleanup and a safe place for the hot appliance. Around 20% of consumers would make this their primary concern. |
Buying pitfalls
-
Choosing by litre capacity alone
A larger cavity does not tell you whether your usual portion will fit on the supplied tray in a single layer. Extra cooking levels are more useful if you also make larger portions or other foods.
Check the supplied basket or tray and its usable cooking area, then measure the appliance and the space needed around it.
-
Following a conventional-oven recipe unchanged
An air-fry setting may need different timing and temperature from a conventional-oven recipe. Thin sweet potato slices can brown before the original recipe’s cooking time is up.
Use recipe conversions as a starting point, check the chips early and turn them if needed. Instant Pot UK advises adjusting temperature and time when converting oven instructions for fresh food.
-
Overlooking heat clearance and crumbs
Countertop ovens need a suitable surface and space for heat to flow. Russell Hobbs’ instructions for its 26680 also call for regular crumb-tray cleaning.
Measure the intended spot, follow your model’s clearance and hot-surface instructions, and clean its crumb tray as directed.
Relevant brands to consider
Russell Hobbs
Its Express range offers two different routes: the 12.6L Express Mini Oven 26090 and the 20L Express Air Fryer Mini Oven 26680.
- Russell Hobbs lists an air-fry setting and mesh rack for the 26680, alongside bake, grill, toast and keep-warm functions.
- The 26090 is a compact convection alternative, but its listed functions do not include a dedicated air-fry setting. Check the supplied tray arrangement if that is your preferred route.
Instant
The 13L Vortex Plus Air Fryer Oven is a compact oven-style option with an air-fry setting and multiple cooking levels.
- Instant describes perforated trays and 360° hot-air circulation, both relevant when arranging chips for airflow.
- Its extra trays and rotisserie features may be more than you need if you will only cook one small tray of chips.
Tefal
The Easy Fry FW606840 is a 20L air-fryer oven aimed at uses beyond a single snack batch.
- Tefal lists air-fry and bake functions, three cooking levels and two racks for the FW606840.
- Consider whether you will use its additional cooking space often enough to accommodate a 20L appliance.
Ninja
The Foodi DT200UK is a larger multifunction countertop oven for people who expect to prepare meals as well as chips.
- SharkNinja lists 10 cooking functions and two-level cooking for this model.
- Its family-meal focus makes exterior size and regular use of the additional capacity important checks for a small kitchen.
Sage
The Smart Oven Air Fryer SOV860BSS4GUK1 is a multifunction countertop oven with an air-fry setting.
- Sage describes dual-speed convection and a Super Convection mode intended for high airflow.
- If you mainly want occasional chips, decide whether you will use its broader cooking functions and controls.

Common questions
Do I need an air-fry setting to make sweet potato chips?
No. A convection oven can bake sweet potato chips without a dedicated air-fry setting. If crispness is your priority, check the available airflow setting and cooking surface, and spread the slices in a single layer, as KitchenAid’s sweet potato chip recipe advises.
How do I adapt an oven recipe for an air-fryer oven?
Treat the recipe’s settings as a starting point and check the chips early. Instant Pot UK’s general guidance for fresh food suggests reducing the oven temperature by about 20°C and cooking time by around 20–25% when converting to air frying; slice thickness, moisture, load and appliance can change the result.
What space does a countertop oven need?
Allow the clearance specified for your exact model and use a suitable heat-resistant surface. For example, the Russell Hobbs 26680 manual specifies a stable, level, heat-resistant surface and 150 mm of space around the appliance for heat flow; do not apply that measurement to other models without checking their instructions.
Can I plug a countertop oven into an extension lead?
Check the oven’s instructions and the extension lead’s rating before use; do not assume every combination is suitable. Electrical Safety First advises against overloading extension equipment or connecting extension leads in a chain.
How should I clean an air-fryer oven after making chips?
Let the appliance cool, then follow its manual for the crumb tray and cooking accessories. The Russell Hobbs 26680 instructions call for regular crumb-tray cleaning and for the tray to remain fitted during use; check the instructions for your own model before putting any rack or basket in a dishwasher.
