Ninja Innovation Use the Ninja DT200UK to quickly and easily prepare all your favourite recipes. On two levels, this 29 L oven cooks whole meals uniformly. There is no need for several appliances because a major meal and a side dish can be prepared simultaneously. More than just a toaster oven, you can cook anything to suit your tastes, from cheese on toast to roast chicken. Rear heat and surround airflow work together with True Surround Convection technology to provide superheated air across the entire oven. Without rotating or flipping your food, you'll get crisp, even results on both racks. You can prepare family-sized meals in as little as 30 minutes, up to 40% faster than a fan oven. Additionally, you won't have to wait long for the oven to heat up thanks to a super-fast preheating period of 90 seconds.
