A convection oven is heated from the bottom, allowing warm air to circulate throughout to heat food. With a convection oven, internal fans circulate heat in the oven to ensure a consistent temperature, evenly cooking food. Some convection ovens add a third heating element in the back of the oven to more evenly cook food.Convection ovens are pricier than conventional ovens, but they offer cooks many benefits.
Convection ovens allow cooks more control in cooking delicate baked goods and evenly baking dense foods like turkeys and hams. Pies and cookies are more evenly browned; pastries come out flakier.
