What is The Ninja Double Stack XL 9.5L?

The Ninja Double Stack XL 9.5L (model SL451) is the latest high-end air fryer available in the Malaysian market.

Unlike traditional side-by-side basket air fryers which takes up more space, this model features two vertically stacked basket drawers, designed to maximize your cooking capacity all the while minimizing clutter in your kitchen. The total capacity is 9.5 litres, divided into two 4.75L drawers. You can cook two big or four medium size ingredients simultaneously using the stacked meal racks, making it great for family meal preps.

Ninja Double Stack XL Air Fryer Specifications:

  • Wattage: 2,470W
  • Weight: 10k.3g
  • Dimensions: H38.5cm x W28cm x D47cm
  • Capacity: 9.5L
  • Material: Ceramic coating; dishwasher safe
  • Settings: 6-in-1 Air Fry, Max Crisp, Roast, Bake, Reheat & Dehydrate​
  • Warranty: 2 years

Design: Space Saving

If you're looking for a reason why you should upgrade, the Double Stack XL's design is the single, biggest defining feature.

Because of its vertical orientation, you take up 30% less counter space than any other side-by-side dual-basket air fryers. Especially to families preparing for Raya open houses, or those who live in smaller apartments and such, the Double Stack XL is truly ideal for tight kitchens.

Despite its "slimmer" built, the air fryer offers a generous capacity, with Ninja claiming it can feed up to 8 people. Each basket drawer can fit and perfectly cook 1.5kg roast chicken. We also like the fact that the basket is small enough to comfortably wash in our small office sink.


Performance: Double Stack Air Fry Technology

With a 2470W power output, this air fryer heats up and cooks quickly, with its unique DoubleStack™ Air Fry Technology which includes 2 removable stacked meal racks that allows for cooking up to 2 levels per basket, and superheated air surrounds both foods in each basket for all-around crisp.

Both the frying basket drawers have independent controls. Using the Sync and Match Smart Functions, you can control cooking time precisely. If you use the "Sync" option, both drawers will be optimised to finish cooking at the same time. Use "Match" and the basket drawers will duplicate each other's settings. This makes the air fryer great for party-hosting moments and such.


6-in-1 Multi-Functionality

The Ninja DoubleStack™ Air Fryer offers six powerful cooking functions, all designed to make mealtime faster, healthier, and more flavourful:

  • Air Fry – Crisp up your favourites with little to no oil.
  • Max Crisp – Extra crispiness for breaded or battered items
  • Roast – Achieve oven-quality results for meats, veggies, and more.
  • Bake – Create sweet treats or savory bakes with precision.
  • Reheat – Bring leftovers back to life with a crispy edge.
  • Dehydrate – Make healthy snacks like fruit chips and jerky.

For more recipe and ideas, I'd recommend thoroughly reading the manual "recipe" book that comes with the air fryer, or visit sharkninja.my for their dedicated Ninja Kitchen recipe portal.

What We Like

Caption: Sync feature lets you synchronise the cooking time for the two different frying basket at once.

- Design and built

Ninja has always been ready to impress with the quality their products offer. Some cheap and even mid-range price air fryer can be pretty expensive, and feels flimsy to handle. During cooking, I would not like to have to be too careful about getting food in and out of my air fryer. 

Thankfully like other Ninja products, this air fryer is just as robust in built. I also like how the air fryer is straightforward to understand. The remote settings and functionalities are neatly displayed. And even if you don't get it right away, the manual it comes with is easy to read, which helps with easy navigation and exploring of such an otherwise advanced appliance (which we know can be overwhelming). 

A small detail I liked was that the metal stack racks are designed with side handles, and when placed in the air fryer, they face upwards. The "handles" have these indented groove design which is meant to help you get the rack out easily.

- Consistent Results: Perfect Doneness Always

Worried about ruining your meals? With this air fryer, even beginner chefs need not fret at all.

Ninja DoubleStack comes with an integrated digital cooking probe (thermometer) that takes the guesswork out of cooking. Ninja has engineered the digital cooking probe for real time temperature monitoring, which tracks internal food temperature as it cooks, so you can achieve your desired doneness with precision.

Using it is easy. Just insert the probe into your food (example, a whole chicken), plug it into the port, and once the food reaches the target temperature- it automatically stops cooking.

Moreover, the air fryer comes with more accessories to help you achieve the best cooking results: two stacked metal racks, two crisper plates and a Chef-inspired Recipe Guide you can learn a lot from.

- Easy to clean

Air fryers can be notoriously tedious to clean, especially if stubborn food debris gets caught.

Ninja Double Stack XL is ceramic-coated, and is certified dishwasher-safe to clean, giving you an easy option to deal with cleaning. Adding on to that is that the removable basket drawers and crisper plate are non-stick. Thus, this helps with food residue to clear off quickly.

Of course, do clean your baskets every time you cook in order to maintain the air fryer's cleanliness for a longer time.

In our experience, the fried food debris came off very easily without much effort and with no soaking. This is approximately 45 minutes after food has cooked.

- Does not require preheating

What makes the Ninja DoubleStack XL stand out from many other air fryers is that it does not require preheating. Usually, preheating is crucial for certain recipes, such as a whole chicken, in order to get consistent heat transfer throughout every part of your dish so that it cooks evenly. 

Ninja has optimised the DoubleStack XL to heat up evenly. Therefore, preheating is not needed no matter what you cook, so you save time cooking with this air fryer.


What We Dislike

- Price

The bitter pill to swallow is that the Ninja's price tag is a premium, pricing at RM1,439.

But for what you'll pay, rest assured that Ninja's products are always known to be very robust, matching professional-level equipment even, and this air fryer feels the same (we had a cooker from 2021 and it's still serving my family well). With that said, the Double Stack XL is an air fryer that'll last you and your family for years. 


Who is this for?

Pros

  • Can cook up to 4 foods at once
  • Premium space-saving built
  • Easy to use with clear control panel
  • Accurate and consistent cooking results with digital probe
  • Smart Sync function so all foods finish at the same time
  • Easy to clean and dishwasher safe drawers
  • Does not require pre-heating

Cons

  • Premium pricing in its category

It's obvious. Whether you're a beginner or intermmediate chef, and you love cooking and hosting for a lot of people, or if you like meal-prepping, the Ninja Double Stack XL is a good pick.

In terms of saving obvious kitchen space (or to have a clutter-free kitchen), this is a solid pick and highly recommended for home cooks and chefs. The Ninja® DoubleStack™ XL 2-Basket Air Fryer serves not just as a time-saver, but also as a beacon for smarter, space-conscious home cooking.
