Sharing a picture of oven instructions on Instagram, one user revealed the official name: a warming drawer.
“The warming drawer is designed to keep hot foods at serving temperature," the instructions state. "Always start with hot food. Cold or room-temperature foods cannot be heated, warmed, or cooked in the warming draw."
According to Yale Appliance's blog, warming drawers are becoming more accessible.
“Prices have become more affordable than they have been in the past. Many freestanding and slide-in ranges sold today feature a warming drawer instead of a storage drawer underneath the oven."
While not everyone will have a warming drawer, they can be purchased separately.
“Warming drawers can also be sold separately and can be built into your cabinetry.”
