General Convection Oven Recipe Conversion Guidelines

There are three commonly accepted methods of converting recipes from conventional oven baking to convection oven baking. 

  1. Bake at the same conventional oven temperature but for a shorter period of time.
  2. Bake for the same length of time as you would using a conventional oven but reduce the temperature by 25 degrees.
  3. Bake for a slightly shorter period of time and a reduced temperature.  This tends to be the most successful method for most ovens.

When Should Convection Cooking Be Used Rather Than Conventional Cooking

Foods cooked in a convection oven cook about 25% - 30% faster than a conventional oven as the hot air is forced around the food.  Foods tend to have less moisture loss and fewer nutrients are destroyed in the cooking process.

One of the most important factors when determining which cooking method is most appropriate for your food is the type of dish or pan you are cooking in.   If the cooking container blocks the flow of air around the food then there is no use in using convection cooking. 

Convection Cooking Is Good For

  • Cookie sheets
  • Shallow pans

Conventional Cooking Is Good For

  • Covered casseroles, pans or dishes
  • Deep roasting pans

Manufacturer Guidelines
Follow the recommendations from the manufacturer of the oven. Your oven typically shipped with a user guide. It is a good idea to familiarized yourself with the specifics for your own oven. If you don't have a user manual then try contacting the manufacture to obtain a copy. Many provide printable copies online.

Air Circulation
Air circulation is important. Don't cover racks with foil. Allow 1 to 1 1/2 inches around pans (also above and below pans for multi-rack baking).

Use Proper Pans
For maximum browning, use pans with low sides, and rimless cookie sheets. Many ovens come with special pans and racks that lift roasts so air flows all around. If possible, place the long sides of the pan parallel to the oven door.

Roasting Guidelines

Roast meats and poultry
Preheating is not necessary. Place meats on a rack in the roasting pan for better browning. Roasting time may be 20 to 30 percent less than in a conventional oven if temperatures aren't reduced. Some ovens offer a special roasting mode that provides top and/or bottom browning or an initial surge in heat in addition to the fan. These modes make it easy to get optimum results in a shorter time.

Small Roasts or Unstuffed Poultry
Do not reduce oven temperatures for small pieces, skinny roasts, or unstuffed poultry. In our tests, we roasted a 3 1/2-pound chicken at 375 |degrees~. In about an hour, about 20 percent less time than for conventional cooking, it was beautifully browned, with succulent flesh.

Dense Roasts & Stuffed Turkeys
For large, dense roasts and big stuffed turkeys, you may need to reduce the temperature 25 |degrees~ during part or all of the roasting time. When you lower the temperature, the meat may be juicier and shrink less, but it will take longer to cook.
