Design and Construct
- Complete set of equipment
- The open door will overhang a typical kitchen counter
- Not probably the most intuitive management panel
So as to supply 28 litres of capability, the VonShef 28L Air Fryer Oven is essentially fairly massive. It measures a surface-absorbing 45.2 x 42.9 x 38.7cm, weighs a hefty 11kg and appears very like a compact standard oven with a drop-down glass door.
Thankfully, its equipment – a rotisserie, two handles, crumb tray, rack, tray (which doubles as a drip tray) and air frying basket – could be saved inside when not in use, so that you gained’t must discover a place for them. Nevertheless, when it’s in use on an average-sized worktop with the door down, it’ll overhang barely.

Two dials for time and temperature flank a management panel that’s a riot of icons and textual content, making it lower than intuitive to set. There are 14 presets: some are icons chosen by the menu button, whereas others are labelled with a phrase. Two – air fry and defrost – are managed by their very own button, whereas buttons for turning on the inner gentle and rotisserie add to the confusion.
Briefly, you’ll want the directions handy for some time. Which isn’t to say there aren’t some good options right here. Inside, you’ll discover six heating components (4 above, two beneath) mixed with a rhombus-patterned panel on the again. This has been designed to assist distribute warmth evenly for sooner, extra constant outcomes.
Efficiency and Options
- Can match a 12-inch pizza and as much as 1kg of chips
- Loads of choices for cooking settings
- 40-230°C temperature vary
The VonShef 28L Air Fryer Oven’s busy management panel isn’t a lot helped by its directions. Throughout testing, we discovered errors and omissions that made utilizing it harder. For instance, default instances and temperatures are listed for every operate, however a few of it isn’t correct, such because the default air fry time listed as 20 minutes, when it’s truly 30, and the default setting for chips being switched with the one for toasting.
There’s no information as to the amount that the defaults are primarily based on, and a scarcity of readability surrounding forms of meals. Which means that you’ll want some expertise or be sure to’re round to verify on the progress of meals to keep away from over- or undercooking.
What we did like was the convenience with which the settings could be toggled to go well with. The fan could be turned off, for instance, which is sweet if it’s not required otherwise you’re cooking meals that’s vulnerable to blowing round, and the timer doesn’t begin counting down till the preheat has completed, so you know the way lengthy one thing has been cooking on the proper temperature.
Time and temperature could be altered as soon as the oven has began, and the vary is helpful – most presets will prolong to an hour, whereas dehydrate will run for twenty-four hours, and the temperature ranges from 40-230°C. The capability can also be spectacular, becoming in a 12-inch pizza and as much as 1kg of chips.
As there’s an air frying operate in addition to a preset for chips, we determined to check the previous utilizing frozen hash browns. There isn’t a lot steerage for cooking meals from the freezer, so we opted for 20 minutes at 180°C, the default temperature, utilizing the air fry basket. After the time had elapsed, we discovered that the hash browns have been crisp however extra so on the tops than the bottoms, which have been distinctly softer.

Subsequent, we used the basket for making recent chips utilizing soaked, washed and dried potato items tossed in a small quantity of oil. The default for this preset was 160°C – a lot decrease than standard when air frying – and 18 minutes – a lot shorter than most additionally. We felt this setting can be extra appropriate for frozen chips fairly than recent, or skinny fries, so we raised the time to 25 minutes and 180°C.
Whereas there was no suggestion of turning the chips, we did so midway by way of cooking. Sadly, this nonetheless wasn’t sufficient for a constant batch. The chips emerged largely pale and lots of wanted extra cooking time to crisp up correctly.

We additionally cooked a rooster utilizing the corresponding preset (35 minutes at 230°C) and the rotisserie fork. The fork is designed to carry an entire rooster as much as 2.5kg, nonetheless, we might counsel there’s some ability concerned with a fowl this heavy. As soon as a tray was in place to catch the fats as suggested, we struggled to get a 1.5kg fowl balanced on the fork with out it dragging.

Throughout cooking, the oven emitted a good quantity of steam and a few smoke as fats and juices hit the weather on the prime of the oven, requiring our kitchen extractor to be on all through. Along with this, juices overflowed from the tray and penetrated the be a part of within the door, leaving puddles on the worktop. Regardless of these points, the rooster was completely cooked, with browned pores and skin, not too crispy, and succulent flesh.

Clear-up afterwards was the largest problem: all of the equipment required hand-washing as they’re not dishwasher protected. Regardless of lots of scrubbing, we have been unable to take away burnt-on grease from the tray and crumb tray, and really feel that non-stick coated equipment can be extra appropriate. The cavity additionally wants cleansing after each use as soon as it’s cooled: extra effort than most air fryers, the place the drawers could be simply cleaned by hand or popped in a dishwasher.
