Key Features
Introduction
I be intimate the convenience of a double - drawer air fryer , but the retort space they take up make them a no - go for many citizenry . With the Ninja Double Stack XL 9.5L Air Fryer SL400UK , you get two drawers , one stacked on top of the other , so the melodic phrase fryer only takes up the same footprint as a individual - drawer model .
With two - layer cookery supply into the mixing , high temperature cooking and excellent upshot across the control board , this is the best two-fold - draftsman air fryer yet .
Design and features
TheNinja Foodi MAX Dual Zone Air Fryer AF400UKshowed the power of dual - drawer air fryers , but it ’s one heck of a beast , learn up a lot of antagonistic outer space . With the Ninja Double Stack XL 9.5L Air Fryer SL400UK , you get the same 9.5 - litre capacity ( 4.75 - litres per drawer ) , with the social unit taking up just over half the counter space by comparison .
Impressively , although the Double Stack is taller than the AF400UK , it ’s only taller by 6 cm , so does n’t look dominating .
heap the drawer vertically , Ninja has had to redesign the system ’s working . Rather than having the warming component and rooter at the top of the pants , as with the AF400UK , they have been relocated to the back of the unit , go down on through the vent in the back of the drawers .
That redesign has one extra benefit : each drawer can cook on two layers with the supply conducting wire rack . For multi - layer preparation , the Double Stack Pro clitoris needs to be dispatch , and anything on the telegram rack needs to be large enough not to fall through the gap .
That aside , two - layer cookery lets you replicate up on capacity , or even cook an entire meal in just a single drawer .
There are a duo of drawback to this cooking system . First , two - layer preparation process well if your layers fake at the same temperature for the same amount of time ; if you ’ve got a mismatch in preparation time , as I had in examination , then you ’ll need to add together one stratum part - way of life through the cook .
Secondly , turning food becomes much harder . While the wire rack have handle , so you could lift them out with oven gloves , doing so while they ’re loaded with food is n’t always hard-nosed .
That ’s not to say that I do n’t apprize the dual - level cooking ; it ’s just that the mode needs to be used with full knowingness of its caveats to get the best results .
Without the telegram rack , each draftsman have a standard 4.75 - litre capacity , with a crisper plate at the bottom . A grip on the front makes it easy to remove a drawer and shake food to help it cook evenly .
Ninja has once again demonstrate that it ’s the master of user interface . Rather than having a complex array of modes design for specific food for thought , such as chips and wimp , the ascendency lie in of the mode ( Air Fry , Roast , Max Crisp , Reheat , Bake and Dehydrate ) , temperature and fourth dimension . Max Crisp does n’t have temperature selection and runs at 240 ° C , with just the fourth dimension selectable ; it ’s designed for foods that need a really crispy finish such as hash Robert Brown .
Ninja provides a useful booklet with suggested modes , temperature and cookery clip for most plebeian food , which make life easier . Overall , the Double Stack is lightning - fast to practice .
Drawers can be used individually , effectively yield you two disjoined air fryer . However , the drawer can be used together , with two unlike modes depend on what you ’re doing .
couple mode sets both drawers to the same options which is useful when you need to double up on the same ingredients , such as cooking twice the amount of chips that you ’d usually do . This mode ’s a dainty time saver as I did n’t have to set each draftsman separately .
Sync mode lease you manipulate on different setting , but the drawers are automatically timed to finish simultaneously . That ’s great for time a complete repast , as I did n’t have to think about when to start the second drawer . smartly , removing either draw during preparation , to turn nutrient , pause both knickers , so they still finish at the same metre .
The Ninja Double Stack XL 9.5L Air Fryer SL400UK is designed in such a way that achieving what you need is easy .
Drawers and accessories are dishwasher safe , although they ’re almost as quick and easy to wash by mitt .
This aviation fryer as a two - year warrant , provided you record it within 28 days of leverage with Ninja .
Performance
I started by cooking a batch of oven chips along with some Pisces digit , using the two - layer cookery mode . As the Pisces fingers command less cooking prison term than the chips , I add these a few minute of arc into the cooking process .
At the end of cooking , my chip were dead and equally cooked , and the fish finger had a nice curt conclusion to them . You ca n’t do well than that , and being able-bodied to use one draftsman for a complete meal is brilliant .
Next , I used the Max Crisp style for hash browns , cooking them from frozen in just 12 minute of arc . The results are incredible , with a tiptop - crisp outside and a downlike inside that rival air fryers ca n’t match .
I also cooked an intact crybaby on the roast setting . correspond a chicken into a drawer entail I could cook an total family - sized meal in just one atmosphere pullet .
cook in just an minute , I used a temperature investigation to make certain that the chicken was falsify through ( it was ) . I was impressed with the results : the peel was very crispy while the wimp stay moist at bottom .
I used the dehydrate mode on apple cut , to get rid of the moisture content . They make a neat snack that will last longer than fresh slices . I also witness desiccate a utilitarian choice for garden herbs .
