How to Preheat a Toaster Oven – A Complete Guide

How to Preheat a Toaster Oven - A Complete Guide

Many home cooks contemplate preheating the toaster oven because of the extra time required or when they don’t know the correct temperature required for a particular recipe.

And that’s the reason I have compiled this detailed oven preheating guide!

Whether you bake or broil in the toaster oven, preheating it at a particular temperature will ensure your food comes out perfectly done. Here’s a breakdown of this comprehensive guide before moving forward:

Preheating a toaster oven can take 5-20 minutes depending on its size, model, and voltage. Since most recipes require an oven preheated at 400-450F, you will have to turn on yours 10 minutes before you put in the ingredients.

But, below the crust, there’s a lot more you need to understand about acquiring that perfect temperature in a toaster oven.

Are you interested in knowing some tricks to bake, broil or roast like a pro?

Stick around, and I’ll help you through this trivial yet crucial kitchen hack.

Do I Need To Preheat A Toaster Oven?

Heating a toaster oven until it reaches the right cooking temperature will ensure your food comes out perfectly done.

When you put the baking tray in a cold oven, its temperature rises slowly, and by the time it’s finished, the cake/bread’s crust is hardened.

Similarly, broiling meat in a cold oven will affect its tenderness and take more time to form the brown layer.

If you’ve recently started cooking, learn to maintain a steady temperature inside your toaster oven, and your recipes will never come out over or underdone.

Another benefit of preheating a toaster oven is the time it saves you. Turn on the toaster oven while you’re mixing or cutting different ingredients and put them in a well-heated oven instead of the cold one.

However, preheating the toaster oven isn’t mandatory; it depends on the recipe you’re making.

When you toast bread slices, bake eggs, or reheat leftovers, you can skip the preheating step and get straight to cooking.

But more complex recipes always require preheating. So the next time you bake cookies, don’t put the dough in a cold oven!

How To Preheat A Toaster Oven?

Preheating the toaster oven isn’t a difficult process, yet some newbies do it wrong and affect their food in the wrong way.

If you’re also unsure of how to preheat the toaster oven, here’s an easy way for you:

  • Plug your toaster oven in the wall electrical outlet and turn it on
  • Turn the heating knob to 400F and close the oven’s door
  • Don’t open the door while your toaster oven is heating because doing so will let some hot air escape
  • If your oven has a digital display, you’ll know exactly when it hits the required temperature, i.e., 400F
  • But if the digital display is unavailable or broken, check your toaster oven’s temperature with a thermometer after 10 minutes of heating.

If you’re happy with the temperature, that’s it. You can now cook anything in your toaster oven without messing with the food’s texture!

How to Test The Accuracy Of Your Toaster Oven While Preheating?

If your toaster oven has been in your kitchen for years, the standard heating time might not suffice.

Also, the accuracy of a specified heating time depends on an oven’s size, so it’s understandable if some cooks don’t see the desired temperature in a short time.

Luckily, you can oversee the preheating process and ensure it’s doing fine while preparing the recipe. Here are some steps to check your toaster oven’s preheating accuracy:

  • Place an oven thermometer on the middle rack of your cold toaster oven and turn it on
  • Set the temperature to 350F, and check back after 6-8 minutes
  • If your oven is well-calibrated, you’ll hear its beep and reading of “350F” on the thermometer simultaneously

But if the oven’s heating element isn’t as accurate as it used to be, you’ll notice the difference between its beep and the actual reading.

How To Make Sure Your Toaster Oven Is Perfectly Preheated?

Argh, charred food again? That must be because you set your oven at a blasting temperature while you only needed medium heat to broil that meat fillet.

Whether you’re preheating the toaster oven or have put the ingredients in it already, remember these two factors to avoid most temperature-related mishaps:

Give The Toaster Oven Some Breathing Space

When the toaster oven is crammed in a cabinet or stuck between other things on your countertop, it can get hotter than you’d need. Therefore, leave some breathing and circulation space around your oven to keep its temperature in check.

Use An Oven Thermometer

Even if your oven has a digital temperature display, using a thermometer will be a smart move.

Regular use and changes in the heating element can alter its timing, and eventually, you’ll never be sure if the reading on display is correct or not. Get a reliable oven thermometer and rule out this worry in one go!

How Long Does It Take For A Toaster Oven To Preheat?

Now that you understand the importance of preheating a toaster oven, you’d be thinking, how long will I have to wait after turning it on?

Although the exact answer to this question varies, some estimations sit well with most toaster ovens.

Electric and gas ovens require different durations to be preheated because their sizes and heating elements are different. Keep reading to know the time you’ll need to follow that particular recipe you’re planning to make!

How Long Does It Take For An Oven To Heat To 500-degrees?

Although sticking to 400-450F temperature is ideal while preheating a toaster oven, you’re still free to choose.

If you’re to bake a large batch of cookies or scones, you’d need an evenly heated oven with no cold air pockets, and setting the heat knob at 500F is good for that.

Most good quality electric ovens take 5-20 minutes to reach 500F temperature when the electricity voltage is stable. And if you’re trying to acquire this temperature in a gas toaster oven, it’ll hardly take 5-10 minutes on high heat.

How Long Does An Oven Take To Preheat To 400-degrees?

450 degrees Fahrenheit is the most preferred temperature for toaster ovens. Whether you’re broiling some veggies or baking pastries, turn on your electric oven for 5-15 minutes, and it will be ready to cater to your culinary needs afterward.

If yours is a gas oven, only 5 minutes at a high heat will suffice.

When in doubt, use an oven thermometer to ensure your oven doesn’t surpass the 450 mark, as it can affect your food’s color and texture.

How Long Does It Take To Preheat An Oven To 375-degrees?

Turn on your electric oven for 5-10 minutes, and it’ll be ready for the recipes that need a 375F temperature. With gas ovens, this duration drops down to 5 minutes at max.

How Long Does It Take An Oven To Preheat To 180-degrees?

Barely five minutes in, and your electric oven will be preheated at 180 degrees Fahrenheit. This temperature is great for heating leftovers and toasting slices when you’re in a hurry and cannot waste time waiting for the oven to heat up.

How Do I Know When My Oven Is Preheated?

If your oven has a digital display and you’re sure it shows correct readings, you’ll know exactly when your oven is ready to cook.

But it’s different with old and somewhat faulty toaster ovens. Here’s how you can know if your oven is preheated or still needs some minutes:

Check Temperature with a Thermometer

  • Get an oven thermometer if you don’t have one; it always comes in handy in the kitchen.
  • Hang the thermometer between the slits of your oven’s middle rack. Make sure it doesn’t directly touch the rack.
  • Turn on the oven and get busy with the meal prep.
  • After 10 minutes, check the thermometer’s reading, and it will likely be at your desired level. You can cross-check this reading with your oven’s indicator screen to know if it’s working fine.

Melt Some Sugar

Melting sugar in the toaster oven is another used and tested trick to check if it is well calibrated on not. Here are a few steps to follow if you go down this route:

  • Add some granulated sugar to an oven-safe dish and place it on the middle rack of your toaster oven. Set your oven to 320 degrees Fahrenheit and turn it on.
  • Wait for 10-15 minutes and see if the sugar granules have started melting or not.
  • If sugar melts during these 10-15 minutes, your toaster oven is well calibrated and ready for all kinds of cooking.
  • And if the sugar granules are partially melted or not melted at all, it means the toaster oven’s heating element is not working well. In this case, you’ll have to wait a little longer to preheat your toaster oven.

Does The Oven Beep When It’s Done Preheating?

Most toaster ovens either beep or a light goes off in them once they reach the set temperature. What you see will depend on the model and the oven’s functionality.

My toaster oven is almost 6 years old, and its light doesn’t work anymore, so I have to check the temperature with a thermometer every time I preheat it for an important recipe.

If your oven is new, its heating coil and beep/light will be intact, so you’ll know when it’s time to start cooking.

Can You Put Food In The Oven While It is Preheating?

Yes, you can put food in a toaster oven while preheating, but it’s better if you don’t. When you put raw ingredients in a cold oven, their temperature rises slowly, and the final dish isn’t evenly cooked.

On the flip side, putting food in a preheated oven not only saves your time but also ensures the food is evenly cooked. If you bake, you will notice that putting ingredients in a cold oven hardens the crust while the lower layers are uncooked.

That’s why I recommend you preheat the toaster oven to provide stable heat to the raw ingredients. Preheating will reduce your cooking time and ensure the food is well-cooked; try and see yourself.

Final Thoughts

Preheating the toaster oven can change your baked and broiled food’s texture and taste altogether. When you’re confident that the oven has hit a certain temperature, you can cook anything in it without worrying about undercooking or food charring.

Most toaster ovens take 10-15 minutes to preheat, which you can easily manage. When you start putting together different ingredients, turn on the toaster on the side, and both things will be ready in no time.

Once you get the hang of your oven’s heating capacity, the recipes you make will speak for your culinary skills. So, keep practicing and keep charred/poorly cooked food out of the question!

Related Questions:

Do gas ovens need to be preheated? Yes, gas ovens also need to be preheated. But since gas ovens’ heating elements are more powerful, you’ll have to be careful about the preheating temperature. Stick to 300-400F while working with a gas oven to avoid food burning incidents, and you’re good.

Why does my electric oven take so long to preheat? There can be two reasons behind this problem, a faulty heating element or poor electricity voltage. Regular usage can reduce an oven’s working capacity, and eventually, it starts to take longer than usual to preheat. Moreover, when the voltage reaching your toaster oven isn’t stable, you cannot guarantee if it will heat up in the said time.

Does it smell while preheating the oven? Toaster ovens release a slight smell when you preheat them, primarily because of the stuck-on food grease or gas. If you notice a hissing sound and smell in a gas oven, immediately turn it off to prevent a mishap. But if the smell isn’t strictly methane, you don’t have to worry. Keep your oven clean and use its self-cleaning mode once in a while to melt all stuck-on food residue and keep these smells at bay.

Do we need to preheat the oven for baking a cake? Yes, preheating the toaster oven is important before you bake a cake. An evenly heated oven rack will ensure the raising agents inside your cake batter get enough time to rise, and there’s no stuck-on residue when you take it out of the tray. Contrarily, putting the cake batter in a cold or slightly heated oven means all ingredients get cooked at different temperatures. To enjoy a nicely baked cake, you’ll have to check on the oven’s heat settings!

What happens if we don’t preheat the oven before baking? The leavening agents in a cake (baking powder, yeast, etc.) require high and consistent heat to work their magic. When you preheat a toaster oven before baking, you give enough room to the raising agents, and as a result, enjoy a well-baked cake. Another reason why you must preheat the oven before baking is the time it will save you.
