The good old oven is our everyday savior. It will not only tenderize that tough meat you bought but also bake mouth-watering, heart-soothing cookies for you in the late hours.
But there is a key to using the oven. No matter if it is gas-fueled or electric, to get the best out of your oven-cooked recipe, you have to preheat your oven.
Preheating means getting your oven hot enough to a temperature of your liking. This ensures the food starts cooking right away.

It is an essential part of cooking, roasting, and grilling your food. If you skip it and put your dish in the cold oven and turn on the heat, the food will not only be undercooked but also might get burnt in some parts.
So knowing when the oven is done preheating, should be going through your mind right now. Well, we are here to discuss that.
How to Know When Oven Is Done Preheating
To know if your oven is done preheating, you don’t have to open the oven door. It will let the heat escape and you will have to go all over the preheating stage again. So how do you do it? There are some simple ways to know when your oven is preheated and ready for your dish to be cooked.
How Long Does It Take To Preheat a Modern Oven
Modern ovens are intelligent not only in functions but also in practicality. You had to use an oven thermometer back in the day to know if your oven has reached the desired temperature. It included not only opening the oven door but also getting a splash of heat on yourself.
Now, modern ovens have everything built in them. You get a digital display, thermostat, and a whole lot of functions. You also get notified with an alarm when your oven is preheated.
Normally modern-day ovens take 20-30 minutes to preheat. No matter what the temperature is, it takes almost the same time, gives or takes.
Older ovens take 7-15 minutes. Which is a bit faster than the modern-day oven. But there is a story behind it.
Why Does It Take Longer for a Modern Oven to Heat Than Older Ones
You might ask the question, well my old oven didn’t take that much time, is my new one broken or something?
The answer is no, your oven is perfectly fine. The reason behind your modern oven taking long is the tech behind it.
Old ovens didn’t take much time because they heated the oven directly. While modern ovens have an extra interior wall that gets heated instead of the whole oven itself. It is not only a safety measure but an efficient way to keep the heat stay longer inside. Making gas or electricity consumption run down by a lot.
How to Tell Your Oven Has Reached the Expected Temperature
Although most ovens come with alarms and timers on them to notify you of the preheating done time, if you don’t have that feature in your oven, you can always do yourself some DIY stuff to know that.
You can get a countertop timer to set the time to check the preheating time manually. It is how people did back in the day. And still do that in the kitchen when they don’t want something to go out of hand in the oven.
The second thing you will need is a thermometer for your oven. It hangs out on the handle of the oven. And has a piece in the oven itself.
When your timer goes off, you can go and check the temperature of the thermometer to see if the oven has reached your desired preheating stage. If not, you can also set the timer again and wait a few more minutes.
There is another modern thermometer that connects with your phone via Bluetooth to let you know the internal temperature of the oven. It doesn’t get destroyed with heat and is a cool gadget to have when you are cooking a heavy steak or roast.
When your oven is preheated, you will get a notification on your smartphone and you can put the dish in your oven.
Frequently Asked Questions
How long does an oven take to preheat?
Depending on your desired temperature, a modern oven takes 20-30 minutes to preheat. While older ovens will take half the time. The number will be 10-15 minutes. It also depends on how your oven functions. As modern ovens heat the internal wall rather than directly the whole oven, it takes a bit longer than older versions of the oven.
Will the oven beep when it’s done preheating?
Yes. Modern ovens that have a timer, and thermostat will make a beeping sound when your oven is preheated. If somehow it doesn’t beep, this means either your thermostat is not working and you will need to check with a professional.
Conclusion
Modern-day ovens come with a lot of functions like timers, alarms, digital display controls, pre-made modes, and so on. They even have self-cleaning functions and child safety locks. Never oven an oven that is in the preheating stage. This allows external air to get into the oven and makes it harder to reach the right temperature. Instead, use an oven thermometer and a counter-timer to maximize your efficiency.
