If you’ve ever microwaved food, you probably know that when it comes out hot, it can be pretty hard to handle. And if you’ve ever experienced overcooked, dried, and tough food that was cooked in the microwave, you probably have some questions about why it happened.
The truth is that microwaves are just like other forms of radiation. They’re capable of heating things up. But microwaves do it differently than other forms of heat, which means they can cause different types of damage to your food.
If you want to understand why microwaves burn your food, you first need to understand how they work and then how they interact with the molecules in your food once they start heating them up!
What causes microwaves to burn food?
The reason microwaves burn your food is because they use super high-frequency waves, which means they penetrate food easily and quickly. These waves also bounce around inside the food, causing water to build up friction that heats up your food.
In most situations, microwaves will dry out and harden your food if left microwaved for too long. If you continue cooking it in the microwave after all the water has left the food, it may end up causing your food to burn and catch fire.
However, the problem with microwaves is that they don’t heat evenly. Certain parts of your food get hot while other spots stay cold. This causes hot spots and cold spots.
In many cases, if you mistakenly believe it’s not cooked, you’ll try to add a few extra minutes to your cooking time and this can lead to charring even if you’re cooking at a low setting.
When microwaves burn food, it is usually because the food is not cooked evenly. This can happen when the food is placed in the microwave unevenly or if the microwave does not rotate the food properly.
What to do before cooking food in a microwave
While the chances of your food actually catching fire in the microwave are pretty slim, it is still possible. If you’re concerned about the possibility of your food burning or exploding in the microwave, there are a few things you can do to keep safe.
- Make sure the microwave is clean. If there is food or grease build-up on the inside of the microwave, it can cause the food to catch fire.
- Don’t overheat the food. This is one of the most common causes of food catching fire in the microwave. If you’re not sure how long to cook something in the microwave, err on the side of caution and cook it for less time.
- Use a microwave-safe dish. If you’re not sure if a dish is microwave-safe, play it safe and use one that is made specifically for microwaving.
- Don’t leave the food unattended. If you have to step away from the microwave while the food is cooking, hit the stop button so it doesn’t continue to cook.
Tips on how to prevent food from burning in a microwave
1. Adjust the settings of your microwave
If you’re using a microwave that has multiple power settings, try lowering the power level and increasing the cooking time. This will help keep your food from overcooking and burning in spots.
2. Try rearranging the food in the microwave
Sometimes, just rearranging what you’re cooking can help! Try putting smaller pieces on top of larger ones so they have more room to cook evenly, or try flipping over some of the pieces so that all surfaces get equal exposure to heat energy from your microwave’s waves (or whatever else makes them work).
3. Lower the power level and increase the cooking time
Just keep monitoring your food and take extra care of how long it’s being cooked. Stand there and keep an eye on the food, making sure it’s looking good and properly spinning.
4. Avoid microwaving different foods at the same time
When you want to cook two or more things, it’s best to do them one at a time. Obviously cooking something frozen along with something warm might end up burning the warm item before it ever gets to the frozen one. If the two items are vastly different in temperature or type, then separate them into different microwave sessions.
5. Don’t leave your microwave unattended while cooking
It’s common sense that this is unsafe but it bears repeating: never leave a microwave unattended while cooking! You could end up burning your food or even starting a fire if you leave the room with something inside it.
6. Keep aware of any burning smell
If your food starts smelling burned, take it out immediately! Do not let it continue cooking if you smell smoke or other unpleasant odors coming from your microwave. It could mean that something has caught fire inside there.
7. Monitor splatters through your microwave door
If you see food splatter through your microwave door, stop what you’re doing immediately. The splatter could cause a fire, and then that would be bad news all around.
8. Keep your ears open for weird sounds while microwaving
If the microwave starts making weird noises—like hissing or sparking—it’s time to turn it off immediately. This could be an indication that the food is overheating or burning (and then you’d have a big problem on your hands).
9. Watch for sparks, flashes, or fires
If there are sparks coming out of your microwave? This is definitely not good! If there are flashes of light coming from inside your microwave? Again, this is not good! And if there’s fire? Well, no need to explain why this is bad news. Just turn off the power immediately and do not attempt to open the door until everything has cooled down completely.
10. Don’t leave old food crumbs behind after microwaving
Leftover crumbs can continue to cook and burn during your next microwave session.
11. Wipe away grease and oils from your microwave regularly
Wipe away grease and oils from your microwave regularly. This will help keep them from getting burned onto your appliance, which is the number one cause of that nasty smell that lingers after you’ve finished using it.
12. Avoid using microwaves with broken control panels and displays
Avoid using microwaves with broken control panels and displays. These controls are important for keeping track of how much time is left before your food is done cooking, so make sure they’re working properly before using them!
What should I do if my microwaved food catches fire?
If your food catches on fire while microwaving, safely unplug the appliance and keep the door closed to contain the fire.
If a fire erupts beyond the microwave, grab a fire extinguisher and activate it at the base of the fire to extinguish the flame.
If the fire becomes too much to handle, get out of the house and call the fire department.
Do not try to extinguish the fire with water because that could cause the fire to wildly erupt.
If you’re in the market for a fire extinguisher, choose a class K fire extinguisher which is ideal for kitchen fires.
What happens if you microwave food for too long?
If you microwave food for too long, it can actually burn or explode.
This is because microwaves heat up food by causing water molecules to vibrate, and if there is no water present, the microwaves may cause the food to catch on fire.
And if it hasn’t caught fire, in many cases once the food runs out of water molecules it will shrivel up and harden making your meal completely inedible.
Depending on how long it takes you to catch this mistake, it can either come out completely hard and dry or it could very well smoke and catch fire.
So, if you’re going to microwave your food, make sure to do it for the recommended time, and never put anything in the microwave that doesn’t have water in it.
Can you still eat microwave-burnt food?
So, can you still eat microwave-burnt food? It depends. If the food is only slightly burnt, it might be okay to eat. However, if the food is severely burnt or exploded, it’s best to throw it away.
If you’re ever in doubt, it’s always better to be safe than sorry. When it comes to microwaves, it’s better to err on the side of caution.
When you have microwave Burns food, it’s almost like any other type of food that has been burned or cooked too long.
However, unlike a charred body and smoke, it’s likely that you’re over a microwaved meal will be tough, dry, and chewy.
Can microwaves destroy vitamins and nutrients if overcooked?
While microwaves are convenient and capable of cooking food quickly, they can destroy vitamins and nutrients if they overcook your food.
In fact, studies have shown that overcooked foods in a microwave lose up to 97% of their vitamin A and E content!
So what should you do instead?
If you want to use a microwave oven for convenience and speed, try heating up leftovers or frozen meals in increments of 30 to 45 seconds while readjusting the food at least once or twice in the microwave to help promote even cooking.
