A Samsung NV51K6650SG 30" Built-In Wall Oven allows you to cook multiple dishes at once and can easily accommodate a big roast, multiple casserole dishes or several racks of cookies. Three racks allow you to prepare enough food for large gatherings. Two fans circulate heat evenly throughout the oven for faster and more efficient cooking. Saves up to 30% more time than traditional conventional ovens. Steam Cook allows you to bake, broil and roast with professional results as it delivers moisture at precise times for a crisp, browned outside and tender inside.
