Here’s How to Preheat a Toaster Oven


Preheating a Toaster Oven

Knowing when and how to preheat your toaster oven is an important part of having your food turn out the way you like. Not all foods require the toaster oven to be preheated, but many do.

In this brief article, we’ll go over the steps to preheating a toaster oven including how long to preheat it for and how to know when it is ready.

How to Preheat a Toaster Oven?

Let’s review the simple steps to preheat your toaster oven.

Set the Temperature

You’ll want to start by setting your toaster oven to the desired temperature. Check the recipe or instructions to determine the correct setting.

Close the Door

In order for the toaster oven to reach the correct temperature, you’ll need to ensure that no hot air can escape. Make sure that the door closes tightly.

Set the Time

Some toaster ovens will have a screen that shows the current temperature–if yours has this feature, you don’t need to set a timer. Simply keep an eye on the display and wait for it to reach the correct temperature. Some models will have an alarm or bell that rings when the programmed heat setting is reached.

If your toaster oven doesn’t have this setting, you’ll need to set a timer to know when your oven will be hot enough to start cooking or baking. 

How Long to Preheat a Toaster Oven?

How long you should preheat your toaster oven depends on what temperature you are setting it for. The higher the temperature, the longer it will take for the toaster oven to preheat. Since each toaster oven model is a bit different, preheating times may vary.

Preheating to 350 Degrees

For a toaster oven to reach a temperature of 350 degrees, you should expect it to take about 10-12 minutes.

Preheating to 375 Degrees

Toaster ovens will generally reach a temperature of 375 degrees within 12-15 minutes.

Preheating to 400 Degrees

It typically takes about 15-17 minutes for most toaster ovens to reach a temperature of 400 degrees.

Preheating to 425 Degrees

You should expect your toaster oven to take approximately 17-20 minutes for it to reach a temperature of 425 degrees.

How to Know When a Toaster Oven is Preheated?

There are three main ways to tell when your toaster oven has preheated. The first and easiest way is to use a toaster oven that has the temperature displayed on its screen. As the temperature inside the oven rises this will be displayed for you to monitor.

The second way to know when your toaster oven is preheated is to use a timer. Once you have set the temperature on the toaster oven, set the timer for 10-20 minutes, depending on how hot you need the oven to be.

Lastly, you can use an oven thermometer to tell when your toaster oven is preheated. Place the thermometer inside the toaster oven and then set the toaster oven to the desired temperature. You will need to periodically look at the thermometer to see how hot the inside of the oven is and if it has reached the correct temperature.
