While every oven is going to be a little different, you're basically looking at three ways to turn a conventional-oven recipe into a convection-oven recipe: Reduce cooking temperature by 25 degrees F (about 15 degrees C). Reduce cooking time by 25 percent. Reduce both temperature and time by less than 25 percent.
When using a convection oven instead of a conventional oven, set the temperature 25 degree lower than usual, and reduce the cooking time by 25 percent. Discover the nuances of cooking in a convection oven with help from a professional chef in this free video on cooking techniques.
If you set the oven to convection bake at 350 degrees F it will run at 350. If your recipe calls for 350 degrees F for say, a roast, you'll need to lower the temp to 325 degrees F to compensate for the air racing around in the oven.
Convection ovens cook food faster than conventional ovens. To cook in a convection oven, follow this easy formula: reduce the temperature by 25 degrees or reduce the cooking time by 25%. Some ovens today even offer convection conversion, eliminating any guesswork!
I generally use the same cooking temperatures for convection, but cut the time by 20-40% depending on what I'm cooking (cut more time for vegetables, less for meat). I make sure to keep an eye on things and check often once I get close to that time since I've found that things burn faster in my convection oven.
Some recipes will suggest regular bake or convection, but as a general rule, don't use the convection setting for delicate desserts and pastries such as custards, souffle, chiffon and angel food cakes, to name a few.
If a recipe calls for baking at 350 degrees in a still oven, reduce the temperature to 325 if baking in a convection oven. Similarly, if a recipe calls for 350 degrees in a convection oven, increase the temperature to 375 degrees to work in a still oven. Watch the cooking time.
Convection ovens cook food faster than conventional ovens. If you've switched out your conventional oven for a convection one, you're probably already aware of the benefits: Faster, more even cooking, better all-over browning, juicier results, and, often times, more nutritional value in your cooked foods.
What happens if you bake at 350 instead of 400? It's just going to take a little longer. From our conversion chart above, 350F instead of 400F will take 1.14 more time. So something that takes 30 minutes at 400F will take 34 minutes at 350F.
Reduce the original baking temperature by 25°F.
For example, if your recipe calls for baking the food in a 375°F oven, set the dial to 350°F. If it calls for 400°F, set it to 375°F. What about 450°F? You got it, 425°F is your convection oven temperature.
Adjust Recipes for Convection Cooking or Baking
For example, if your recipe instructs you to bake at 350°F for 60 minutes, you'll convert this to 325°F and begin checking at 45 minutes.
The main differences between convection bake and regular bake are the cooking speed, temperature and heat distribution, and the end result. Convection baking is often faster and provides a more consistent bake across multiple racks.
PREHEAT oven until thermostat signal light goes out indicating that the oven has reached the desired temperature. The oven should preheat to 350° F. within 10 to 15 minutes. (Note: To conserve energy, DO NOT turn on the oven until absolutely necessary - about 15 minutes before actual cooking is to start.)
One frequent complication for new convection owners is how to adjust their recipes, all of which are written for still ovens. The rule of thumb is this: Reduce the oven's temperature by 25°F. Make your first check of baking time 10 minutes earlier than the recipe says.
This formula will help you find the right cooking time to adjust by multiplying the initial time by the percentage difference caused by temperature change. For example, if you want to cook from 400˚F (200˚C) to 450˚F (230˚C), then that would be: 400 ÷ 450 = 0.89 or 89%. From here, you can adjust the expected time.
Dependeing on the recipe and the size pan, baking at 325 can add 10 minutes or even double the baking time.
Yes, 350 F converts to 180 C and 180 C converts to 350 F. How much longer do I cook something at 350 instead of 400? Cooking something at 350 instead of 400 generally means you need to increase the cooking time by 20%-25%, though the exact time will depend on the type of dish and its size.
When roasting meat and poultry, set the oven temperature to 325°F (163°C) or higher. Explore the charts below to learn how to get great results every time you cook.
There's no question that the standard oven temperature of 350°F gets the job done for baking up muffins and quick breads.
The first option is decreasing the time by about 25 percent (multiplying the time in minutes by 0.75) while retaining the temperature set forth by the recipe for a conventional oven. The second option is to reduce the temperature by 25 degrees and abide by the cook time in the recipe for a conventional oven.
When you are using a convection oven, you would need to adjust the recipes. If you don't adjust the recipe correctly, you can end up with burnt or overcooked food. Baked foods such as bread, cookies, and cakes are most susceptible to this.
Don't use convection for cooking cakes, quick breads, custards, or soufflés.
So, if you press the convection button and set it to 350°F (about 180°C), the oven will preheat the oven to 325°F (162°C).
Convection heat uses less energy, requires shorter cooking times, and leaves food more evenly cooked.
About Convection Oven Temperature Conversion
Simply set the temperature 25 degrees lower than the original recipe bake temperature calls for. Be sure to also adjust meal cooking times by 25% to avoid overcooking entrees. As a general rule of thumb, check about 20 minutes earlier than the normal finish time.
