If making the most of your counter space is important to you, the Double Stack (DoubleStack in the US) is the air fryer to go for. Not only does it have two cooking drawers with an overall 9.5L/10QT capacity, but the cooking racks allow you to stack food in two layers in each drawer, giving you much more flexibility. If you often tend to cook a protein and several vegetable sides for dinner, you’ll be able to do it all in the Double Stack without resorting to your oven, microwave or hob.
Like Ninja’s other dual-drawer air fryers, it has an easy-to-use control panel, with match and sync functions. Although it has has fewer modes than many other models – there’s air fry, max crisp (for frozen food), bake, roast, reheat and dehydrate – you can adjust them by time and temperature to cook almost anything you want.
However, thanks to its design, the heat sources are at the backs of the drawers and, when we tested it, we found that it did cook some types of foods slightly unevenly. As there’s no shake alert, you’ll need to remember to step in midway and mix up potatoes or fries. Altogether though, it provided fast, crispy results and is an efficient cooker.
There are now more Double Stack models to choose from. There’s a compact model, the 7.6L/8QT SL300 (UK)/SL201 (US). It comes in black, instead of the original’s dark grey, and is available from Ninja in the UK for £229.99 and from Ninja in the US for $199.99.
There’s also the Double Stack XL with Smart Cook system. It has the same dimensions as the original but features a cooking probe for meat and fish, making it a better choice if you often use your air fryer to cook from fresh. It’s priced at £289.99 from Ninja UK and $249.99 from Ninja US.
Finally, if you’re in the UK, you can buy the original Double Stack XL in a special edition white colourway. You can buy it from Currys in the UK and it’s also priced at £269.99.
Who should buy the Ninja Double Stack?
Buy the Ninja Double Stack if you want to cook meals with lots of separate side dishes – or if you want a two-drawer model and have limited counter space.
Ninja Double Stack: Further considerations
As the heat source is at the back of the drawers, instead of overhead as is usual with Ninja models, this model does cook less evenly than others. You’ll need to be extra vigilant about remembering to shake up or shift around the contents of the cooking compartments. Remember: there’s no shake alert.
