What is a Convection Oven?

A Convection Oven is a type of oven that uses fans to circulate hot air in order to increase the speed and evenness with which food cooks & the ability to cook the food evenly can be especially useful while baking food. Due to the circulation of air throughout the oven, the entire cooking space can be utilized more efficiently.

Cooking Tips with Convection Oven

It is important to read the user manual thoroughly to learn more about the nuances of your oven.

  1. The dish closest to an active heating element cooks the fastest in a conventional oven.
  2. Place the racks in place before using the oven because they will get very hot very quickly.
  3. Check the food around 5-10 minutes before the full cooking time. As a result, you will reduce the risk of burning dishes.
  4. If you are cooking food that cooks fairly quickly, such as cookies, the adjustments that need to be made are smaller compared to the times when you are preparing things that take a long time, such as meat joints.

How To Do Convection Oven Conversion Using Manual Methods?

Below are three simple methods for converting conventional oven cooking times and temperatures into convection oven times and temperatures.

Method 1: Lower the Cooking Temperature

It is usual to reduce the oven temperature by 25°F when baking cakes, bread, or other desserts. However, you should only do this if you can turn off the fan.

Method 2: Lower the cooking Time

Roasting meats typically requires reducing the cooking time by 25% and keeping the temperature the same.

Method 3: Lower cooking Time and temperature simultaneously

It may be appropriate to reduce both the temperature and the time when preparing potatoes, casseroles, and custards. If you choose this approach, it is usually effective to reduce the temperature by 15° to 20° and the time by 10% to 15%.

Solved Example on Convection Convert Calculation with Steps

The recipes for dishes prepared in a convection oven typically call for lowering the temperature, time or both temperature & time. convection conversion will help you with this if it necessary in case. Otherwise, the food may become spoiled.

Example:

Make the Convection Oven Conversion for the following cooking dishes:

  1. Baking dough
  2. Cooking Chicken Legs
  3. Custard

Solution:

  1. If a recipe instructs you to bake the dough at 350°F for an hour, then we should reduce the temperature by 25° F. So, the final temperature should be 325°F (350 – 25 = 325) for an hour.
  2. If you are using a convection oven and the recipe instructs you to cook chicken legs at 300°F for 1 hour (60 minutes), then we should reduce the time by 25%. That is total cooking time should be 45 minutes.
  3. If you are making custard, if that recipe said to bake for 40 minutes at 270° F, then we have to reduce the time & temperature. So, we will now bake the custard in a convection oven for 35-36 minutes & at 222.75° F.

FAQs on Convection Oven Temperature Conversion Calculator

1. How do I convert cooking times for a convection oven?

Conversion for convection oven, To convert cooking times for a convection oven you can either reduce the temperature by about 25 degrees or cut the cooking time by 25 percent. You can use  oven temperature time conversion calculator for this in our website.

2. Do you need to adjust the cooking time for the convection oven?

Yes, you need to adjust the cooking time for the convection oven if the cooking is done from a traditional recipe. In such a case, some timing or temperature adjustments may be needed. There is a calculator in our site called  convection oven calculator may help you with this. Along with this,  oven to toaster oven conversion calculator also available.

3. How much should you adjust baking temperatures when using a convection oven versus a conventional oven?

You should adjust baking temperatures to 25°F lower than the recipe suggests using a convection oven versus a conventional oven. Oven to convection oven calculator and ( conventional to convection calculator and convection oven conversion calculator) will help you with this.

4. What temperature is 350 degrees in a convection oven?

The equivalent of 350 in a convection oven is 375 degrees in a still oven and the equivalent of 350 degrees in a still oven is 325 in a convection oven.
