KitchenAid KCO128CU

Manufacturer: KitchenAid

The KitchenAid KCO128CU is an oven-style air fryer designed for countertop use, offering a 21-litre cooking capacity that accommodates a range of meal sizes. It supports eight labelled cooking modes — air fry, roast, broil, toast, bake, keep warm, dehydrate, and reheat — spread across 12 total functions, covering a broad spectrum of everyday cooking tasks. A viewing window and interior light allow users to monitor food during cooking without opening the door.

The unit runs on 1800W and covers a cooking temperature range from 27°C up to 232°C, with a preheat function and dual heating elements for more even heat distribution. Controls are not digital, and there is no shake reminder feature. It has no smart home integration — neither Alexa nor Google Assistant compatibility is supported — and smartphone remote control is absent. The basket and accessories are not listed as dishwasher-safe. Physically, the KCO128CU measures 432 mm wide, 406 mm deep, and 287 mm tall, weighing approximately 7.2 kg, and it comes with a 1-year warranty.

Pros
  • A 21-litre oven-style capacity accommodates larger quantities of food than many compact air fryers
  • 12 functions covering air fry, roast, broil, toast, bake, keep warm, dehydrate, and reheat reduce the need for multiple appliances
  • Dual heating elements help distribute heat more evenly throughout the cooking chamber
  • A viewing window combined with an interior light allows food to be checked without interrupting the cooking cycle
  • A preheat function ensures the oven reaches the target temperature before cooking begins
  • The temperature range extends down to 27°C, enabling low-heat tasks like proofing or gentle warming
Cons
  • The basket and cooking accessories are not dishwasher-safe, requiring manual cleaning after each use
  • There are no digital controls, which may make precise temperature and time adjustments less convenient
  • No shake reminders are provided, so users must track timing manually for foods that need turning
  • The appliance has no smart home integration and does not support Alexa, Google Assistant, or smartphone remote control
  • At 7.2 kg and with a 432 mm wide footprint, it occupies a considerable amount of countertop space
Who is this for?

The KCO128CU suits home cooks who want a single countertop appliance capable of handling a varied cooking workload, thanks to its 12 functions spanning air frying, roasting, baking, dehydrating, and more. The 21-litre oven-style capacity makes it a practical fit for households that regularly prepare meals for multiple people, where a smaller basket-style unit would fall short. Users who appreciate being able to monitor their food mid-cook without lifting a lid will find the interior light and viewing window genuinely useful. The wide temperature range down to 27°C also makes it suitable for those who occasionally need low-heat functions like gentle warming.

Who is this NOT for?

Users who prefer straightforward digital controls for precise time and temperature input will find the absence of digital controls a drawback, as manual adjustments may be less accurate or intuitive. Those who cook foods that require regular shaking or turning will need to track timing themselves, since no shake reminders are included. Anyone with limited counter space may struggle to accommodate the appliance's 432 mm width and roughly 7 kg weight. Finally, users who rely on smart home ecosystems for kitchen automation will find this unit unsuitable, as it offers no compatibility with Alexa, Google Assistant, or any smartphone remote functionality.

The KCO128CU measures 432 mm wide, 406 mm deep, and 287 mm tall, giving it a moderately substantial countertop footprint. It weighs approximately 7.2 kg, which makes repositioning manageable but not effortless. The basket and cooking accessories are not dishwasher-safe, so cleaning must be done by hand.

Final Verdict

The KitchenAid KCO128CU positions itself as a versatile, multi-function countertop oven for households that want more than a single-purpose air fryer. Its 21-litre capacity paired with 12 cooking functions — ranging from air fry and bake to dehydrate and keep warm — make it a genuinely flexible kitchen tool for everyday cooking needs. Some trade-offs come with the territory: the lack of digital controls, no smart home integration, and the need for hand-washing the accessories will matter to certain users. For those who prioritise cooking versatility and capacity over app connectivity or automated reminders, the KCO128CU offers a well-rounded specification set that should serve a busy household kitchen reliably.
