This 30'' Self Cleaning Total Convection Double Wall Oven features our new Total Convection system, which enables cooking modes like No Preheat, Air Fry, Slow Cook, Steam Bake, Steam Roast, Convection Bake, and more! No preheating eliminates time wasted waiting for your oven to heat up - simply place your food in the cold oven and get to mealtime, in no time. It's best used for single rack baking of frozen or pre-made items and food that needs to cook for longer than 10 minutes. Air Fry allows you to make healthier and more delicious meals for the entire family, right in your oven. With Slow Cook, your food cooks slowly and at a lower temperature (as low as 100° F), allowing you to lock in moisture and flavor without over or undercooking your food. With Steam Bake, steam evenly circulates throughout the oven cavity, resulting in breads and muffins that rise higher and are light and fluffy.
