The Nutri Ninja Double Stack XL 2-Tier Vertical Air Fryer features two drawers that stack on top of each other, requiring much less counter space than a traditional air fryer . With two drawers and 6 cooking functions, it's perfect for large families and lots of guests, as each 4.75-liter drawer can hold a whole roasted chicken or 1.4 kg of fries, perfect for serving up to eight people. The 6 cooking functions, cooking times and temperatures can now be combined into 2 separately controlled drawers, so you can prepare all your dishes at the same time, even in smaller kitchens. At 38.5 cm high, it also fits under wall cabinets. The Double Stack hot air fryer technology offers double the capacity: cooking on four levels at the same time for evenly crispy results. By inserting the included double grill racks in each drawer, the cooking surface is doubled. Each drawer has its own heat source and a fan at the back, providing 360° air circulation for even cooking on all four levels and crispy results all round. The multi-level cooking rack is perfect for chicken thighs with asparagus, salmon fillets with new potatoes, beef burgers with fries or a selection of party dishes. You can combine different cooking functions, times and temperatures in each drawer. The SYNC function ensures that both drawers are ready at the same time, so you can enjoy freshly prepared main courses and side dishes together or serve a buffet of freshly prepared dishes. The MATCH function uses the same settings in both drawers to prepare larger quantities of food. With the Double Stack XL SL400EU air fryer cooking up to 55% faster than an oven, you can have your family's favourites on the table in just minutes.

If you want to eat alone, use just one drawer to prepare smaller portions. Each drawer also has a crisping rack insert, which ensures that hot air surrounds the food and cooks it to perfection. The Double Stack XL requires little or no oil, so your favorite foods have up to 75% less fat than conventional frying methods. In addition to frying, the Double Stack XL can also fry, bake, dry, reheat and cook from frozen to extra crispy with Max Crisp. Cooking with the fryer also uses less energy than an oven. The stylish control panel is easily accessible from the side and makes it easy to select the desired settings for each drawer. The Ninja fryer automatically stops cooking when the digital timer expires. The packaging includes a recipe booklet with lots of ideas to get you started and cooking charts to help you get the most out of your appliance. The non-stick drawers, crisping racks and grill racks are dishwasher safe and easy to clean.

Specifications

It is important to know

The Ninja SL400EU air fryer is best suited for families or anyone who often cooks multiple dishes at once, thanks to its two drawers and larger capacity. Before buying, it is worth considering the space on the kitchen counter, the practicality of daily cleaning and whether you will really take advantage of all the advanced features. This model is best suited for those who appreciate the variety of meal preparation and want to simplify cooking.

• If you have very little space on your kitchen counter, pay attention to larger dimensions; two drawers also mean more volume.
• With regular use, two separate drawers make it easier to prepare different dishes at the same time, but they mean separate cleaning and more components.
• Families or users who prepare larger quantities of food benefit most from two independent drawers; the appliance may be a bit too large for one person.
• The digital control panel allows for more transparent program setting, but times must be manually adjusted for dishes that require specific temperatures or durations.

In practice

👨‍👩‍👧‍👦 Family use

🟢 The volume and two drawers allow you to simultaneously prepare two different dishes for several members or larger portions without the need for an intermediate cycle.

🍟 Preparing popular quick meals

🟢 Built-in programs simplify baking fries, chicken or frozen meals; preparation is quick and user-friendly.

👩‍🍳 Casual cooks and experimentation

🟡 If you often prepare simple, small meals or live alone, you will only use a portion of the capacity; in this case, performance may be less optimal due to the size of the appliance.

🏡 A complement to a classic oven

🟢 As a supplement, it can take on the task of reheating, baking, or quickly preparing snacks during the week, saving time and reducing the use of a conventional oven.

Answers to frequently asked questions

Can I prepare completely different dishes in both drawers at the same time?

Yes, two separate drawers allow for independent program settings; we recommend matching dishes with similar cooking times for optimal results.

How difficult is cleaning after regular use?

All removable parts are separate and can be washed individually; although they may be dishwasher safe, consider extra cleaning with the two-bowl space.

Is the appliance suitable for a small kitchen?

Due to its larger capacity and two drawers, it takes up more counter space, which is not ideal for very small kitchens.

What types of food are most practical to prepare?

The device is great for potatoes, vegetables, chicken, frozen meals and larger meals where you need to prepare two food groups separately.

Can a deep fryer be a perfect replacement for an oven?

In practice, it does not replace the oven for larger roasts, pizza or bread baking; but it is excellent for quick, smaller meals and snacks.
