How to Preheat Oven: Important Steps You Shouldn’t Miss

Have you ever noticed most baking recipes start by preheating the oven? I, too, once wondered what the rationale behind that is. While the term ‘preheating’ may sound simple, the actual process is quite meticulous. If you are unsuccessful in doing this process correctly, your dishes will also be likely to fail ultimately.

Baking requires having the right temperature. It is best to ensure that the oven’s temperature has reached its ideal setting and that you do not get too much heat by opening the gate before throwing your favorite cooked dish into the oven.

If you are wondering how to preheat the oven the right way, read on to know more.

Why Preheat the Oven?

Preheating the oven is one of the frequently ignored steps in baking or roasting. What many people do not realize is that preheating the oven can make a massive difference in the dish.

Here are four reasons why you should preheat the oven:

1. Browning Meat

Browning Meat

Have you ever heard of the term “Maillard Reaction“? Browning or the Maillard reaction creates a flavor and shifts the food’s color. Meat would not have much flavor until the Maillard reaction happens. Hundreds of flavor compounds are formed in the process. In turn, these compounds create more flavorful substances.

The Maillard reaction is characterized by each meal variety with a unique range of flavor substances. Browning can only occur when temperatures are higher than 300°C, so you’ll need to prepare your stove if you’re searching for an excellent black sear on the beef or chicken before baking.

2. Leavening Agents

When subjected unexpectedly to high heat, leavening agents, including baking soda, yeast, and baking powder, do not occur in a cold-starter oven.

3. Uneven Cooking

Have you ever experienced putting a chicken or meat inside the oven and ended up having rough brown patches all over them? This could signal that your oven wasn’t preheated well before starting your cooking session.

4. Food Safety

Meats that are not cooked well can cause severe health risks. Therefore, it is never a good idea to put your chicken and other meat straight into the oven without preheating.

How Long To Preheat An Oven?

The time it takes to preheat an oven depends on the manufacturer and model you are using. There are two types of ovens – the electric oven and the gas oven.

It should take about 10-15 minutes for electric ovens to preheat. Modern stoves have a quick pre-heating characteristic. In 7 to 10 minutes, these stoves can preheat. A convection oven can, for instance, be preheated in under 6 minutes. It can also take approximately 5 to 10 minutes of preheating for ovens with a noticeable base baked component. It also takes a short time for gas-powered stoves to get completely warm.

Nevertheless, there are various factors that may also impact your oven’s preheating time. Examples of these factors include but are not limited to the following:

  • A hidden baking component providing filtered heat
  • A wall oven mounted on a reduced voltage takes a longer time to preheat than one mounted on a higher voltage
  • Frequent opening of the oven’s door while preheating is ongoing
  • Unused rack in the oven
  • Room temperature

Steps on How to Preheat the Oven

Once the oven is turned on, it rises slowly from room temperature to maintain the desired heat. If your food is still uncooked after using your oven for a prescribed time, your oven is probably cool, and it may take another 5 to 10 minutes to cook depending on the level of doneness. On the contrary, you might be running hot when your food appears hard or burnt.

The incorrect temperature of your baked goods may also result in unintended chewiness.  A prepared stove will ensure that your souffles cook at the correct heat before they can deflate and wash out your meringue.

So, to have a perfectly cooked dish, preheat the oven using the following steps.

Step 1: Getting to know the oven you are using

Your oven is not only a unit, it’s a partner in cooking everything that your family and guests will love. And with all partners, knowing them is the cornerstone to a healthy relationship. The more we know our oven, the more convenient it is to operate.

The user’s handbook will assist you to know how you should care for your stove and how to use it if you use comparatively fresh ovens. This helps you know how to preheat and how to go about with your oven.

Some electric-powered ovens create a buzzing noise or specify the correct temperature on their LCD screens. When the temperature gauge is present on an outdated oven, spend in an oven thermometer only when it is no longer so reliable.

Step 2: Decide when to switch on your oven

At the very beginning, you do not have to preheat the oven just yet. Like all ingredients, reading the whole recipe before starting is an excellent practice, and that’s how you understand when to switch your oven on.

You don’t need to have your oven in full heating mode if you need an hour to prepare your meal before putting it in an oven. Instead, set the time. Set the oven around twenty minutes before ultimately finishing your meal preparation. This is sufficient time to let your oven reach the correct temperature and adjust to that heat.

Timing is, therefore, essential for a perfectly cooked meal. It’s easier to heat electric ovens that have convection engines so that even 10 minutes should be enough time. However, due to the slower air circulation, gas ovens will take more time. So, it is advisable to preheat the oven for about 5-20 minutes. Some gas ovens, however, in particular, outdated models, may operate at an increasingly high temperature without stabilizing, so examining the temperature and letting it get warmed up first is an excellent practice.

Step 3: Examine what’s inside the oven

Open the oven to ensure that everything is taken away. If you stock products including baking tools, in your oven, take them out and put them aside. When necessary, organize the rack levels. Most oven shelves are put in the center of the stove, but the dish you cook sometimes needs to be at a lower or higher section of the oven. See your recipe and remove the oven rack and position it to the correct level if needed. The oven’s interior walls should have tight edges where you can place your rack.

Dishes that need to be crispy and browned on top, including reheating lasagnas and casseroles, are usually cooked on the upper part of the oven. Foods like cookies, cupcakes, and cakes, unless the recipe says otherwise, should be positioned at the mid-rack. Meals, including pizzas and plain bread, are put on the underside of the oven and need to make it crunchy and brown.

Step 4: Starting the oven by turning it on

Switch on the oven, determine the temperature, establish the temperature setting. To get the correct temperature, refer to your food recipe. Oven temperature is usually the very first stage of every recipe. Just hold the button down and switch to the correct temperature so that the oven temperature ends up at the right temperature.

Step 5: Waiting time

Wait until the required level of temperature is reached. The majority of advanced ovens have a configuration that can allow you to see the existing temperature or give you a beeping sound when ready. Some ovens show a small amount of light when the temperature is accurate. Usually, this light is near the temperature dial of the oven.

In most ovens, the proper heating time takes 10 to 15 minutes. When you have an outdated oven, you might not have a dial with the various temperatures on it; only an on-off switch can be installed. If this happens, merely switch the oven on and take 10 to 15 minutes before you put the food in.

Other Important Points to Remember

Other Important Points to Remember when preheating the oven

  1. Take an oven thermometer into consideration. The temperature in the oven is sometimes incorrect and does not correspond with the heat of the panel. The real temperature will be indicated by an oven thermometer, which is usually positioned within the oven. Instead of hoping for the signal or for the oven to beep, use a thermometer. Turn the stove on and adjust the temperature when the oven utilizes a pilot light. Before rotating, you may have to click the button gently.
  2. You have to modify the label if the oven is filled with gas marks rather than Fahrenheit or Celsius. You must go online and use a digital device for conversion.
  3. The pilot light sometimes leaves or must be activated before every use. In this case, make sure the temperature dials are ‘off,’ and the pilot light is located easily. Hold a flame by the pilot hole, and light up a match. Take away the match as the pilot light ignites. Turn the temperature up mildly if the pilot light does not ignite.
  4. If you have a digital oven, press the button brown, then set the temperature. To adjust the temperature, make use of the up and down arrows. Hit the ‘Start’ button once the temperature has been established. The digits will change on display. The figure represents the oven temperature inside. Wait until the heat increases, and the actual value is reached.
  5. Place the meals inside the oven when it hits the correct temperature. Gas ovens warm up more quickly than electric ovens so that the suitable temperature of your oven is within 5 to 10 minutes. Keep the gate of the oven closed if otherwise provided in the recipe. Keep your oven’s door closed and look into your food, as the temperature in the oven will drop off, thereby causing a longer cooking time. Do not place too many food meals on the lower rack if you have a bunch to bake and plan on cooking using both shelves. The heat may not reach the food at the upper rack.
  6. If you smell gas, take caution. You can have a gas leak if you smell gas while cooking. Immediately turn the oven off. Avoid using electrical equipment. That can lead to an explosion. Leave the windows open and leave the house. Contact emergency departments by telephone or mobile phone. Never use the mobile phone inside the house.


What is the ideal temperature to preheat an oven?

The ideal temperature to preheat an oven depends on the recipe you are using. Most recipes will specify the required temperature in the instructions. However, as a general rule, preheat your oven to a temperature that is 25°F to 50°F higher than the required temperature to compensate for heat loss when you open the oven door.

Can I preheat my oven for too long?

Preheating your oven for too long is not recommended, as it can lead to overcooking or burning your food. Generally, preheating your oven for 10 to 15 minutes is sufficient. However, some ovens may take longer to reach the desired temperature, so be sure to refer to your oven manual for specific instructions.

Can I put food in the oven while it is preheating?

Can I put food in the oven while it is preheating

It is not recommended to put food in the oven while it is preheating. This is because the oven temperature may not be consistent, and the food may not cook evenly. Additionally, opening the oven door to put the food in can cause heat loss and affect the oven temperature.

Do I need to preheat a toaster oven?

Toaster ovens usually require preheating, especially when baking or roasting. Refer to your toaster oven manual for specific instructions on preheating.

What should I do if my oven does not have a preheat setting?

If your oven does not have a preheat setting, you can still preheat it by turning it on to the desired temperature and waiting for it to reach that temperature. Use an oven thermometer to check the oven temperature and adjust it as necessary.

Can I open the oven door during preheating?

It is not recommended to open the oven door during preheating, as it can cause heat loss and affect the oven temperature. If you need to check the oven temperature, use an oven thermometer and check through the oven window.

Should I use a baking stone when preheating my oven?

Using a baking stone can help regulate the oven temperature and ensure even cooking. However, be sure to preheat the baking stone along with the oven to prevent cracking.


Knowing how to preheat the oven is an important aspect of every food recipe. Preparing the oven by removing all baking tools and racks and securing that the oven door is properly closed are factors that need to be taken into account to ensure proper preheating and achievement of the desired temperature.
