Air fryers work by convection, meaning they circulate hot air around your food, ensuring every bit of surface area is exposed to the oil and heat. You simply need to spray or pour a little oil onto whatever you’re cooking before switching on the appliance – although you don’t always have to use oil if you don’t want to. Add just a dash, however, and a clever chemical process called the Maillard reaction creates a crispy result with far less fat – up to 99% in some cases. The ability to use different modes in each basket – for example, grilling bacon in one drawer while air frying hash browns in the other – gives the Instant Vortex Plus a real edge for people seeking to make whole meals in their air fryer. Like its predecessor, the FlexDrawer comes with an array of thoughtful functions including its match and sync settings, the former of which allows you to match the time and temperature of both sides of the fryer without having to input all the information twice, while the latter syncs up both sizes of the fryer, so they finish at the same time, even when at different temperatures of cook times. You’ll also recognise all the classic settings for air frying, roasting, baking, reheating, proving and dehydrating, as well as the Max Crisp setting, which allows you to crank up the heat to a whopping 240ºC. Basket style with heating elements: tall, slim air-fryers feature a main unit with heating elements and fans. These have slide-out baskets or trays that slot into place inside. As they tend to have a smaller cooking area than oven-style fryers, in testing we found even results were more likely if the cooking was paused occasionally to rearrange or toss the food around. Some fryers will cut out automatically when you do this, some will need to be paused if you want accurate timings.

The best models will have a number of basics you should look out for. These include weight and temperature settings, so you can adjust the heat and cook time to suit your ingredients.There’s no doubt that Tefal’s Genius range is expensive, but you really won’t find a line of air fryers that do the job better. Most also come with a recipe booklet for culinary inspiration, which is ideal if you’re new to air frying.

In our testing, the FlexDrawer proved to be just as efficient as the Dual Zone and we found the addition of the removable divider incredibly useful. Foods cooked faster and more evenly than in both our oven and some other models of air fryer. It’s an excellent all rounder for large capacity cooking. Despite being a budget-friendly option, the T17023 was no slouch in testing, cooking oven classics such as spring rolls and hash browns to a commendable crispness and performing solidly when tasked with more delicate items like meat and vegetables. Its compact dimensions will fit neatly into smaller kitchens or onto already crowded countertops, and the controls couldn’t be simpler: two physical dials allow you to set the cooking temperature between 80ºC and 200ºC and set a timer of up to 30 minutes. The Dual Zone’s Max Crisp function is also worth shouting about, as it cooks thinner frozen foods such as chips, onions rings, and nuggets in a fraction of the time it would take a standard convection oven. During testing, one portion of frozen potato lattices came out perfectly crisp and golden in just six minutes, compared to the recommended 15-minute oven cooking time stated on the bag. This air fryer can also bake, roast, dehydrate, and reheat, making it a versatile tabletop multi cooker.Can it be repaired independently?
