Making the Most of Convection Settings
Most recipes are written for a conventional, static oven where heat radiates from the top and bottom elements. Flipping the convection switch turns your oven into an air-driven machine that excels at crisping skins, browning roasted vegetables, and baking multiple trays at once.
Mind the airflow
Convection works by moving air; if you crowd the oven with large baking sheets or deep sides, you block the currents and negate the benefit. Leave at least an inch of space between pans and the oven walls.

Airflow is the heat source
The fan converts your oven from a radiant heat box into a convection dryer; it is intended to create a golden, crisp exterior, not just to cook things faster.
The method.
Adjust the temperature
Always subtract 25°F from the suggested temperature in your recipe. If the recipe calls for 400°F, set your convection oven to 375°F.
Switch the pan type
Use low-rimmed sheet pans rather than high-sided roasting pans. High sides act as shields, preventing the air from reaching the food and creating steam rather than crispness.
Set the timer early
Start checking your food at the 75% mark of the total suggested cooking time. Convection can cause a sudden jump in color and texture once the moisture at the surface evaporates.
Manage the rack placement
If baking on multiple racks, stagger the pans so one is not directly above the other. This ensures the air has a clear path to swirl around each surface.
When it doesn't go to plan.
Never use convection for soufflés, delicate cakes, or quick breads; the moving air can cause the top to set before the structure has finished rising.
For roasted potatoes or chickens, convection is your best tool for achieving a uniform, deep brown finish.
If your oven lacks a specific 'convection' button but has a fan icon, that is your convection setting.
The ones that keep coming up.
Can I use convection for everything?
No. Avoid it for anything that needs to rise significantly in the first few minutes, as the fan can disturb the batter or dough before it sets.
Why does my food get dark before it is cooked through?
Your oven is likely too hot or the airflow is restricted. Drop the temperature another 10 degrees and ensure your baking sheets aren't too large for the cavity.
