1. An oven comprising:
a case that defines a cooking chamber;
a broil heater configured to generate radiant heat toward the cooking chamber; and
a convection module comprising a convection heater configured to heat air and a convection fan configured to supply the air heated by the convection heater into the cooking chamber,
wherein the oven is configured to operate in an air-fry mode based on performing a plurality of heat stages, the plurality of heat stages comprising a first heat stage, a second heat stage, and a third heat stage that are configured to be sequentially performed,
wherein the oven is configured to:
receive a cooking ingredient in the cooking chamber before performing the first heat stage,
in the first heat stage, drive the convection fan before driving the convection heater,
drive the broil heater and the convection heater alternately in each of the first heat stage, the second heat stage, and the third heat stage,
drive the broil heater for a first driving time in the first heat stage,
drive the broil heater for a second driving time in the second heat stage, and
drive the broil heater for a third driving time in the third heat stage, and
wherein the first driving time of the broil heater is longer than each of the second driving time of the broil heater and the third driving time of the broil heater.
