    Overview

    The Ninja DoubleStack XXXL Smart 9.5L 2 Drawer Air Fryer SL451 redefines air frying with its innovative stacked design, maximizing both cooking capacity and counter space. Unlike traditional air fryers, its DoubleStack Air Frying Technology enables you to cook up to four different foods at once, ensuring even, crispy results across every dish. With two independently controlled 4.75L drawers, each featuring a removable stacked meal rack, you can prepare full meals efficiently without compromising flavour or texture.
    Designed for busy kitchens, the XXXL 9.5L capacity easily accommodates two 2.3kg whole chickens or a generous portion of wings, making it perfect for feeding large families or hosting gatherings. Despite its large capacity, the space-saving, vertically stacked design keeps your benchtop clear and is 30% slimmer than standard two-drawer air fryers. It fits seamlessly under most cabinets while still offering unmatched cooking power.

    Ninja’s Smart Cook System, featuring an integrated Foodi Smart Probe, takes the guesswork out of cooking. Whether you prefer your steak rare or well-done, the precise temperature control ensures perfect doneness at the touch of a button. Additionally, the Smart Finish & Match Cook functions let you either sync different foods to finish at the same time or easily duplicate settings across both drawers for full-capacity meals.

    With six versatile cooking programs—Air Fry, Max Crisp, Roast, Bake, Reheat, and Dehydrate—this powerhouse adapts to all your cooking needs while using up to 75% less fat than traditional deep frying. Experience faster, healthier, and more convenient cooking with the ultimate multitasking air fryer.
    6-in-1 Versatility

    With 6-in-1 cooking functions, you can Air Fry, Max Crisp, Roast, Bake, Reheat, and Dehydrate, giving you endless meal possibilities. From crispy snacks to full-course meals, this versatile air fryer ensures perfect results for every craving with minimal effort.

    Smart Finish & Match Cook

    Smart Finish lets you cook two different foods with separate settings and have them finish simultaneously. Match Cook syncs settings across both zones for full 7.6L capacity meals, ensuring convenience, precision, and perfectly timed dishes for effortless family cooking.

    DoubleStack Technology

    Doublestac Air Frying Technology features two removable stacked meal racks per drawer, allowing you to cook four foods simultaneously. Superheated air circulates evenly around each item, delivering consistent crisping and perfectly cooked results in both baskets without extra oil.

    Space Saving Design

    The space-saving slim design is 30% slimmer than traditional two-drawer air fryers, maximizing counter space while doubling cooking capacity. It fits easily under kitchen cabinets, offering a compact yet powerful solution for preparing multiple dishes without sacrificing efficiency or performance.

    Terrible! Wasted money!
    I got this airfryer for Mother's Day, and I couldn't be any more disappointed. I have used it half a dozen times, and no matter what I do the food doesn't cook. I have owned an airfryer (not a Ninja) for years and had no issues at all. My mum and my son both have the side by side version and are very happy with it. I now wish I had of purchased the same.
