Microwaves were invented in 1945, and since then they have become an essential tool for the kitchen. Microwaves are an incredible invention that has changed the way we cook. They can heat up food quickly and evenly, so there’s less chance of burning or overcooking anything. However, microwaves can’t do everything; for instance, they’re not good at defrosting food because it doesn’t get hot enough to melt ice crystals effectively. And some foods are too delicate for a microwave. So here’s what you should never put in your microwave oven:

Whole Eggs

Microwaving whole eggs can cause them to explode, and the results can be messy and dangerous. The shells of eggs are porous, which means that they allow steam and moisture to escape. When you microwave an egg, the heat causes the water inside the egg to vaporize quickly which can cause it to explode. Microwaving eggs without the shell is safe but you should break the yolk membrane of an unbeaten egg before microwaving to allow the steam to escape. And cover the container with a lid, plastic wrap, or a paper towel to contain any mess.

Hot Dogs

Heating hot dogs in the microwave can cause them to burst open, and the hot dog filling can splatter all over your oven. This is because hot dogs are filled with a meat mixture containing high levels of fat and water. When these ingredients are heated up, they expand and create pressure inside the hot dog. If the hot dog isn’t cooked evenly, this pressure can cause it to burst open. And if the hot dog filling gets on the walls of your oven, it can be difficult to clean off.


Coffee is one of those foods that people seem to have strong opinions about – you either love it or hate it. But even if you’re a coffee lover, you should never heat up your coffee in the microwave. Heating coffee in the microwave can cause it to develop an unpleasant taste, making it more acidic. This is because microwaves heat food by causing water molecules to vibrate. And when these molecules vibrate, they create friction, which leads to the development of undesirable flavors.


Fish is a healthy and delicious food, but you should never heat it up in the microwave. This is because microwaves can cause fish to smell and taste unpleasant. The problem is that microwaving fish can create harmful toxins like polychlorinated biphenyls (PCBs) and heterocyclic amines (HCAs). These toxins are known to cause cancer, so you definitely don’t want them in your food. Fish also contains fats, and when these fats are heated up in the microwave, they can turn into harmful compounds called aldehydes.


Rice is a staple food in many cultures, and it’s a great source of carbohydrates and nutrients. But you shouldn’t heat rice up in the microwave. This is because microwaving rice can cause it to become overly moist and sticky. When rice is heated in the microwave, the water molecules inside the grains start to vibrate. This creates friction, which leads to the development of moisture and stickiness. This can make the rice less appetizing.

Breast Milk

Heating breast milk in the microwave can cause it to lose some of its important nutrients. This is because microwaves can cause the milk to heat up unevenly, which can destroy some of the nutrients. In addition, microwaving breast milk can also create harmful toxins. This is because microwaves can cause the milk to heat up too quickly, which can lead to the formation of harmful compounds. Your baby’s health is definitely more important than a quick and easy meal!

If you’re not sure whether or not a food is safe to microwave, it’s best to avoid it. Microwaves can be a great tool for the kitchen, but there are some things that they just can’t handle. So next time you’re planning on cooking something, take these foods into consideration and choose an alternate method.
