Ninja DoubleStack XL 2 Basket Air Fryer 9.5L
Summary
The Ninja DoubleStack XL 2 Basket Air Fryer 9.5L offers a clever vertical design, large capacity, and impressive cooking versatility. Its six cooking modes, four-layer capability, and easy-to-use controls make it an excellent appliance for UAE households seeking convenience, performance, and efficient use of kitchen space.
Introduction
The first air fryer prototype was created in 2006 by Dutch engineer Fred van der Weij. The first commercial air fryer reached the market in 2010. Over the past few years, air fryers have transformed modern kitchens. What started as a healthier alternative to deep frying has evolved into a versatile appliance capable of roasting, baking, dehydrating, and reheating. Among the brands leading this revolution, Ninja has built a strong reputation for combining innovation with practicality. Ninja debuted a pressure-cooker-and-air-fryer hybrid—the original Ninja Foodi—in 2018.
From its early single-basket models to the popular Dual Zone series, Ninja has consistently focused on making cooking easier for busy families. The company later introduced the DoubleStack concept, designed to provide large cooking capacity without occupying excessive counter space.
The latest Ninja DoubleStack XL 2 Basket Air Fryer 9.5L takes this philosophy even further. Instead of placing 2 Baskets side by side, Ninja stacks them vertically. The result is a slimmer design that still offers generous cooking space for large families. With six cooking modes, independent baskets, and the ability to cook four layers simultaneously, the appliance promises convenience without sacrificing performance.
After spending time with the Ninja DoubleStack XL 9.5L, I found it to be one of the most practical air fryers for homes where kitchen space is precious, yet cooking requirements are anything but small.
Design and Specifications
One of the first things I noticed about the Ninja DoubleStack XL is its unusual design. Unlike conventional dual-basket air fryers that occupy a large section of the countertop, this model uses a vertical arrangement. It comes with dimensions of 38.5 x 28 x 47cm and weighs 10.3kg.
The appliance feels solid and well-built. It is not lightweight, but the extra weight gives it a sturdy and premium feel. The exterior consists of BPA-free plastic with a dark grey finish. Fingerprints are less noticeable, and the overall appearance blends well with modern kitchens.
The 2 baskets feature a PTFE non-stick coating, while the crisper plates use Nano-ceramic coating. Both are dishwasher safe, making cleanup effortless.
Ninja DoubleStack XL 2 Basket Air Fryer 9.5L – Control Panel
The vertically oriented control panel slightly protrudes from the body, making it easy to access. The control panel comes with an LED display that shows temperature and time. Below the LED display is the touch panel, which has prominent 1 and 2 indicators indicating the separate functions of the 2 baskets. Below the basket indicators are the six cooking modes: Air Fry, Roast, Max Crisp, Reheat, Bake, and Dehydrate.
Below the function indicators are the Temperature and Time touch controls, followed by a multifunction rotary dial that adjusts both settings. Below the knob, you will find the touch control buttons: Double Stack Pro, Sync, and Match. And finally, you have the Power and start/stop button.
The stacked design makes the unit approximately 30% slimmer compared to traditional dual-Basket models. Despite the compact footprint, the total capacity remains an impressive 9.5 litres.
Ninja DoubleStack XL 2 Basket Air Fryer 9.5L – Six Cooking Functions
Air Fry
The Air Fry mode is designed for healthier everyday cooking. It uses rapid hot air circulation to produce crispy results with little or no oil. During my use, it worked exceptionally well for French fries, chicken wings, nuggets, and frozen snacks, delivering a golden texture without the greasiness of deep-frying.
Max Crisp
Max Crisp mode operates at higher temperatures and is ideal for quickly cooking frozen foods. It reaches temperatures up to 240°C, allowing ingredients to become crispy in less time. I found this setting particularly useful for frozen fries, mozzarella sticks, and breaded chicken, producing restaurant-style crispiness with minimal effort.
Roast
The Roast function turns the Ninja DoubleStack XL into a compact convection oven. It is suitable for meats, vegetables, and complete family meals. During testing, roasted chicken and mixed vegetables cooked evenly while retaining moisture inside. The generous 9.5-litre capacity makes it ideal for larger portions and gatherings.
Bake
Bake mode provides a convenient alternative to a traditional oven. It is perfect for preparing cakes, muffins, cookies, pastries, and casseroles. I was pleasantly surprised by the even heat distribution, which produced consistent baking results. This function adds versatility, making the air fryer suitable for more than savoury dishes.
Reheat
The Reheat function helps restore leftovers without drying them out. Unlike a microwave, which can make food soft or unevenly heated, this mode brings back crispness and texture. Pizza slices, fried chicken, and pastries regained much of their original taste and crunch, making leftovers enjoyable again.
Dehydrate
Dehydrate mode uses low temperatures over extended periods to remove moisture from food gradually. This function is excellent for making homemade dried fruits, vegetable chips, herbs, and beef jerky. I appreciated the ability to prepare healthy snacks without preservatives while maintaining flavour and nutritional value.

Usage – How to Use
Using the Ninja DoubleStack XL is surprisingly straightforward. For this review, I prepared mushrooms with spices and cheese. I also prepared stuffed capsicum filled with vegetables and topped with cheese.
Later, I used the Bake function to prepare mushroom chicken with cheese in a baking dish.
Step 1 –
I inserted the crisper plates into the baskets and placed mushrooms seasoned with spices and cheese on one level. Below, I arranged stuffed capsicum topped with cheese.
Step 2
Load ingredients into each Basket.
Step 3
Select either Basket 1 or Basket 2.
Step 4
Choose one of the six cooking functions: For the first round of cooking, I selected the Air Fry mode for the mushrooms and stuffed capsicum. Later, I switched to Bake mode for the mushroom chicken dish.
Step 5
Adjust the temperature and cooking duration. I used different temperatures and cooking times because the stuffed capsicum required additional heat and a longer cooking duration.
For the mushroom chicken dish, I increased both the cooking time and temperature to achieve a nicely browned top layer.
Step 6
Press Start.
The appliance also includes:
- SYNC Mode, allowing different foods to finish cooking simultaneously.
- MATCH Mode, which copies settings from one basket to another.
This feature becomes particularly useful when preparing large meals for the family.
Step 7
Once cooking is complete, wait until the display shows “COOL”. After the cooling cycle finishes, remove the Baskets and serve the food.

Daily Usage Experience
After regular use, I found that the DoubleStack XL excels in convenience, especially when preparing two dishes simultaneously at different temperatures and cooking times.
Excellent Space Saving
The vertical arrangement is its biggest strength. It occupies noticeably less width compared to most dual-zone air fryers.
For UAE apartments and compact kitchens, this design makes perfect sense.
Four-Layer Cooking
The supplied racks effectively turn the 2 baskets into four cooking zones.
I could prepare: Chicken wings, French fries, Vegetables and Fish. All at the same time. One thing I learned is that successful four-layer cooking requires understanding the ideal temperature and timing for each ingredient. Some experimentation may be necessary to achieve the best results.
Powerful Performance
The 2470W power output provides fast heating. Food cooks significantly quicker than a conventional oven while consuming less electricity.
Digital Control Panel
The side-mounted control panel is bright and easy to understand.
Individual controls for each basket make the operation simple. Even first-time users can quickly master the interface.
Easy Cleaning
One feature I genuinely appreciated is how easy it is to maintain. The baskets and crisper plates are dishwasher safe. Daily cleanup takes only a few minutes.
The exterior can be cleaned easily with a damp cloth or wet wipes, which is useful for removing inevitable oil and grease splashes.
Quiet Operation
Compared to some high-powered air fryers, the noise level remains reasonable. The only noticeable sound is the beep that signals the start and completion of cooking.
Ideal for Families
With six different cooking options and a capacity of 9.5 litres, the appliance comfortably serves four to six people. For gatherings and weekend meals, it can handle larger portions as well.
Ninja DoubleStack XL 2 Basket Air Fryer 9.5L – Power Consumption
The Ninja DoubleStack XL 2 Basket Air Fryer 9.5L comes with a rated power output of 2470W, making it one of the more powerful air fryers available in the UAE market. At first glance, this may seem high compared to conventional kitchen appliances. However, during my daily usage, I found that the appliance compensates with significantly shorter cooking times. Most dishes were ready much faster than when using a traditional oven, which helped keep overall electricity consumption under control.
Another advantage I noticed was the reduced heat generated inside the kitchen, something that becomes particularly important during the hot summer months in the UAE. The ability to cook two different meals simultaneously also helps save time and energy. While actual power consumption depends on cooking duration and temperature settings, I found the Ninja DoubleStack XL to be an efficient appliance for everyday family cooking, especially considering its large 9.5-litre capacity and four-layer cooking capability.
Ninja DoubleStack XL 2 Basket Air Fryer 9.5L – Minor Limitations
The basket dimensions may feel restrictive when cooking a whole chicken weighing around 1.5kg. The best option is to cut into pieces and divide between the 2 baskets.
My earlier, different-brand Air-fryer had a water-mist option in the Basket. This helped keep the food moist and prevent dryness. Ninja DoubleStack XL 2 Basket Air Fryer 9.5L does not have the option, but there are ways to create mist in the vertical double-stack air fryer.
What is the Water Mist Effect? A Useful Trick Rather Than a Built-In Feature
One thing worth mentioning is that the Ninja DoubleStack XL 2 Basket Air Fryer 9.5L does not include a dedicated steam or water mist system. Unlike some Ninja multi-cookers that feature built-in steam functions and water reservoirs, the DoubleStack XL relies entirely on dry convection cooking.
During my usage, I found that the rear-mounted fans circulate hot air very efficiently across all four cooking levels, delivering excellent crisping performance. However, this concentrated airflow can sometimes dry out delicate foods, especially when using the supplied wire racks. To counter this, some users employ a simple trick by lightly misting the food with water before placing it inside the basket. This can help retain moisture and produce juicier results while maintaining a crispy exterior.
I found this particularly helpful when preparing chicken breasts, fish fillets, and certain vegetables. Another useful technique is to add a small amount of water beneath the crisper plate. This can help reduce smoke caused by grease dripping from foods placed on the upper rack during multi-level cooking.
It is important to note that water should never be sprayed towards the rear interior wall of the Baskets, where the heating elements and fan intake vents are located. Doing so could damage the appliance and potentially affect the warranty.
Overall, while the Ninja DoubleStack XL does not offer steam cooking, these simple methods can enhance moisture retention and improve cooking results for selected recipes without compromising the appliance’s outstanding crisping capabilities.

I particularly enjoyed the four-layer cooking capability, SYNC mode, and easy cleaning. Although the premium price places it above entry-level competitors, the excellent build quality and versatility make it a worthwhile investment for households that rely on an air fryer daily.
