Convection Oven

A convection oven is equipped with a fan and exhaust system that actively circulates hot air throughout the oven chamber. Conventional ovens rely on natural thermal radiation and gravity, which can create hot and cold pockets of air. By contrast, a convection fan creates a uniform temperature environment, removing the boundary layer of cool air and moisture that surrounds baking food. This leads to efficient heat transfer: foods cook up to 25% faster and brown more evenly. Convection is highly prized for roasting meats, baking flaky puff pastries, and crisping cookies because the circulating air dries the surface quickly to promote crispness and caramelization.

However, the active air current can cause delicate batters like soufflés, angel food cakes, and quick breads to tilt, drift, or form a crust before they have fully risen, leading to cracks. When baking standard recipes in a convection oven, you must lower the temperature by 25°F (15°C) and check for doneness early.
