Convection ovens cook food much faster than traditional ovens, because they have a fan that circulates the heated air throughout the oven. This keeps your cookies from getting crispy on the outside and mushy on the inside. The convection oven also allows all racks to cook at the same time, evenly. In a regular oven, the rack farthest away from the heat won't be done at the same time as the food on the rack closest to the heat. Cooking with a convection oven can be a lifesaver.
Place the cookie dough on aluminum cookie sheets. Turn your convection on, and set the temperature for 25°F less than the recipe's instructions. (If the recipe calls for cooking the cookies at 325°F, set your convection oven for 300°F. Bake your cookies for the same amount of time as the recipe calls for. When your cookies are finished, you will notice their nice golden-brown color, and that they are cooked evenly both in the middle and at the edges.
In order to properly cook a turkey in the convection oven, use a baking sheet that doesn't have high sides. This way the air will be able to reach all parts of the turkey with ease. Prepare your turkey as desired, then set the convection oven to the temperature listed on the package. Meat should always cook at the recommended temperature. Here is the tricky part: In a convection oven your turkey will be done faster, so you will need to figure out a new cooking time. First, read the instructions that came with your turkey and see how many hours the turkey should bake for. Then subtract 25 minutes for each hour. So a turkey that must cook four hours in a regular oven only needs to cook three hours in a convection oven. You can always use a meat thermometer to make sure the turkey is completely cooked before removing it from the convection oven.
Baked potatoes should have crisp skin and a fluffy middle. Using a convection oven will help you cook your potatoes just right. This is true for both Idaho potatoes and sweet potatoes. Pierce the potato with a fork, and place it on an aluminum baking sheet. Set the temperature of the convection oven to 375°F, which is 25 degrees less than a traditional oven. Bake the potato for 45 minutes. Be very careful when serving the potato, because it will be extremely hot.
