The invention provides a baking method and device and an electric oven. The baking method comprises the following steps: after a preset baking temperature is determined, controlling a heating piece to pre-heat a baking cavity for a preset time; after the preset time is up or the temperature of the baking cavity reaches a preset temperature threshold, controlling an air heating assembly to bake articles in the baking cavity; and controlling a fan to blow air into the baking cavity in pre-heating and baking processes, wherein the temperature of the baking cavity is higher than a preset baking temperature when the preset time is up or the temperature of the baking cavity reaches the preset temperature threshold so as to control the temperature of the baking cavity to be maintained at the preset baking temperature. Through the technical scheme, while the temperature in the baking cavity is distributed evenly, the baking time is shortened.
