The multifunctional device combines four cooking methods in one compact unit: steaming, oven baking with top/bottom heat, flat grilling, and inverter microwave. This offers both gourmet cooks and beginners numerous options to prepare recipes and favorite dishes quickly and healthily. In addition to vitamin-preserving steaming, reduced-fat cooking is another specialty of the NN-DS59N. For this purpose, the durable 4-in-1 combination oven comes with a baking tray that drains fat and even makes flipping hot foods unnecessary.
