Ninja AF100UK Air Fryer – Compact Powerhouse for Healthier, Faster Cooking
For those seeking a balance between healthy cooking and convenience, the Ninja AF100UK Air Fryer offers a highly practical solution. With its 3.8-litre capacity, four versatile functions, and rapid cooking performance, this air fryer is designed to suit small to medium households that want delicious, crispy results without relying on oil.
Stylish, Compact Design
At first glance, the Ninja AF100UK stands out with its modern grey and black finish and compact, upright design that saves counter space. Measuring H34.5 cm x W27.9 cm x D33.8 cm, it fits comfortably in most UK kitchens, even where worktop space is limited. Despite its small footprint, it feels sturdy and well-built, weighing 4.4 kg—a manageable size to move or store when not in use.
The control panel is digital, clear, and easy to operate. Each function is well-labelled, and the bright display allows you to monitor cooking time and temperature at a glance. The basket and crisper plate are coated with a durable non-stick finish and are dishwasher safe, making cleanup effortless after every use.
Energy-Saving Performance
Energy efficiency is one of this model’s standout features. The Ninja AF100UK can save up to 55% on your energy bills compared to conventional ovens, based on typical UK testing using the air fry function. The smaller cooking chamber and powerful heating system mean it uses less energy while cooking food faster—a welcome advantage for households aiming to reduce both time and costs.
During tests with everyday meals—chips, chicken, sausages, and vegetables—the air fryer consistently produced hot, evenly cooked food in significantly less time than a fan oven. For instance, fish fingers cooked perfectly crisp in about 10 minutes, compared to nearly 20 in an oven.
Healthier Cooking with Little to No Oil
Air frying is all about crisp texture with minimal fat, and the Ninja delivers. Its rapid air circulation technology cooks food quickly and evenly, creating that golden-brown finish associated with deep frying but with up to 75% less fat (compared to traditional deep-fried methods).
The 3.8 L basket accommodates up to 900 g of fries or a 1.35 kg whole chicken, making it ideal for 2–4 people. Whether preparing family dinners, snacks, or sides, the air fryer can handle everyday cooking with ease. I found that vegetables retained their natural flavour and colour while meats came out juicy inside and crisp outside, even without preheating oil.
Four Cooking Functions for Versatility
One of the Ninja AF100UK’s best features is its 4-in-1 functionality, offering much more than just air frying.
-
Air Fry – The core function delivers crispy chips, chicken wings, and roast vegetables with minimal oil.
-
Roast – Ideal for meats, potatoes, or baked vegetables, producing even browning and tender results.
-
Reheat – Revives leftovers without making them soggy. Pizza, chips, and pastries regain their crisp texture in minutes.
-
Dehydrate – A rare addition at this price point. Perfect for drying fruit, herbs, or homemade snacks like apple chips or beef jerky.
Switching between functions is seamless via the digital control panel. Each mode maintains accurate temperatures and consistent airflow for even cooking across the basket.
Cooking Experience
Cooking with the Ninja AF100UK is straightforward. Simply set the time and temperature (adjustable for all modes), place your food in the basket, and let the machine do the rest. You’ll appreciate how quietly it runs, with only a soft fan hum during operation.
In practice, chips took around 20 minutes to reach a golden crunch, while chicken breasts cooked perfectly in 15 minutes. The air fryer reheats leftovers in just 3–5 minutes—ideal for busy days or late-night snacks.
The non-stick coating ensures food doesn’t cling to the basket, and cleaning afterward is simple—just remove the basket and plate, pop them in the dishwasher, and you’re done.
Convenience & Ease of Use
-
Fast preheat: The unit reaches temperature quickly, often within a minute, unlike traditional ovens that may take 10 minutes or more.
-
Simple controls: Time and temperature adjustments are intuitive. Even first-time users will feel comfortable within minutes.
-
Portable and easy to store: Its compact body means it fits neatly into most cupboards if you don’t want it on display full time.

Chef-created recipe guide: Included with the appliance, it helps you explore a range of meal ideas from day one.
Practical for Everyday UK Homes
The Ninja AF100UK is well-suited to couples, small families, or busy professionals. It replaces several appliances in one—acting as a mini oven, fryer, reheater, and dehydrator—all while using less energy. For households mindful of electricity use, this is a strong advantage, especially when energy costs remain high.
It’s also perfect for smaller kitchens, flats, or student homes, where space efficiency matters. The quiet operation and easy cleaning make it ideal for regular daily use without hassle.
Durability & Warranty
The build quality feels premium for its class. The non-stick coating remains intact after repeated use, and the crisper plate retains its shape and performance. The air fryer comes with a 2-year guarantee upon registration (UK & ROI only), reflecting the brand’s confidence in product longevity.

The Ninja AF100UK Air Fryer strikes a near-perfect balance between compact design, fast performance, and healthy results. It’s energy-efficient, versatile, and easy to clean—everything you want in a kitchen appliance that simplifies mealtime.
