How and Why Do You Need to Preheat Oven

Usually, every recipe begins with the words: “preheat the oven.” What does it mean? How long does it take to do it? Isn’t it easier and more budget-friendly to put the dish in a cold oven and only then heat it up? In this article you will learn how and why do you need to preheat the oven and how to do it properly.

What does “preheat the oven” mean?

How and why do you need to preheat the oven

When a recipe tells you to preheat the oven, it means that you need to turn on the oven and wait for it to reach the specified temperature before putting your dish inside.

The process of turning on the oven and the waiting time for it to heat up is called preheating the oven.

Preheating the oven allows for even cooking and ensures that your dish will turn out as intended.

FAQ about how to preheat the oven

How long does it take to preheat the oven?

It usually takes about 15-20 minutes for a conventional electric oven to heat up to 180oC (350oF), but if your oven has an indicator light, it will let you know when it’s ready.
By the way, you can buy an oven thermometer that will show the exact temperature inside the oven.

Do I need to preheat the oven before baking?

Definitely yes. If you skip preheating and put your dish in a cold oven, the cooking process may not go as planned.
This is especially true for baked goods like puff pastry, yeast, or shortbread dough.
In addition, the cooking time in the recipe is based on the fact that the oven is already heated.
This means that instead of 30 minutes it may take 50-60 minutes.

How long should I preheat my oven?

Look in the recipe at what temperature the selected dish should be cooked.
Set the required oven temperature and time it for 15-20 minutes (on a regular clock or set a timer).
Then place the dish in the oven and cook for as long as indicated in the recipe.

Well, not preheating can lead to your food not cooking evenly or thoroughly.

For baking things like puff pastry, yeast dough, and shortbread, you need a hot oven right from the start.

When you preheat the oven, your cake will come out perfectly – fluffy, tasty, and with a nice golden crust.

The fats melt, the sugar caramelizes, and everything happens in the right order for the best results.

How do you preheat the oven properly?

  1. Just turn it on before you start cooking.

    It usually takes about 15-20 minutes for an electric oven to heat up, depending on the temperature you need.
    This time is usually enough to make a simple dish.
    If a recipe requires a long preparation time, turn on the oven halfway through the cooking process.

  2. Prepare the oven

    Make sure to check inside the oven for any extra pans or racks.
    Additional items take away some of the heat, thereby increasing the heating time and disrupting heat distribution in the oven.

  3. Check what level you need to cook at

    For most baked goods like cakes, pies, cookies, and muffins, the middle rack in the center of the oven is the way to go.
    If you want a golden top and crispy crust on casseroles and lasagna, place the baking dish on the top level. For pizza and flatbreads with a golden-brown bottom, the lower level is your best bet.
    If the recipe doesn't specify a cooking level, just stick with the middle level.

  4. Turn on the oven and set the desired temperature

    Read the recipe carefully to find out at what temperature it is recommended to bake the dish.
    In my step-by-step recipes, this information is in the first paragraph.

  5. Wait for the oven to preheat

    Most modern ovens will let you know when they're ready either by displaying the temperature on the screen or with a sound signal.
    Some ovens have an indicator light that turns off when the desired temperature is reached.
    This light is usually near the oven temperature sensor.
    If you have an older oven without temperature control, turn it on and wait 15 to 20 minutes before putting your dish in.
    It's a good idea to use a thermometer to ensure the oven is at the right temperature.
