Can You Microwave Milk?

by Charlie

Milk is a food item that is consumed in every country of the world. It is one of the oldest liquid foods that mankind has drank for nourishment. It is used in tea, coffee, pastries, cheese, candy, and all sorts of cooking recipes.

Apart from the traditional cow’s milk, there are many other variants of milk nowadays – we have almond milk, hemp milk, rice milk, soy milk, coconut milk, oat milk, kefir, and lots more. In fact, because of how many available milk options we now have, it is common to run into situations where you’re confused about which milk to use. 

Regardless of all that, milk is a very nutritional food. It is packed with proteins – both whey and casein proteins – that help reduce blood pressure, boost one’s mood, and facilitate muscle growth. Milk also contains the popular lactose which many people around the world are intolerant to. If you’re lactose intolerant, you can find something else that works for you among the other available milk options. 

Typically, milk is heated to certain temperatures when it’s being pasteurized. The purpose of pasteurization is to kill off some harmful bacteria in the milk. However, pasteurization is not the only process that requires milk to be heated – there are times when we also heat our milk for a specific purpose.  

Assuming you need to heat some milk, what method will you use?

Can you microwave milk? Yes, you can microwave milk. With the microwave set to high, heat milk in the microwave while stirring it at 15-second intervals. The milk should attain room temperature within 50 seconds of heating, while boiling takes about 2 – 3 minutes.

What to Know When Microwaving Milk  

Microwaving milk is not a complex process. Milk is usually heated when you want to feed a baby, make some cheese, or make yogurt.

However, you must be careful because the microwave can get hot very fast. If milk is overheated inside the microwave, it will boil over and mess up the microwave’s interior. Stir the milk at 15-second intervals while it boils in the microwave. 

If you’re trying to heat milk for a baby, the microwave is not a safe option. The reason is that microwaves heat milk unevenly and cause some parts to be dangerously hot for the baby. Milk that’s intended for a baby can be brought to room temperature by submersion in water. 

Although heating milk in the microwave is simple and fast, there are a few other effective options that work as well. I’ll be providing some information on those later in the article.  

How to Heat Milk in the Microwave 

Because of how hot the microwave gets, you must be careful when heating milk in it. It would be improper to leave milk boiling in the microwave without paying any attention to it. The microwaving process is best done gradually with the milk in the proper container. Here are some easy steps to follow when microwaving milk: 

  1. Pour a 250ml measure of milk inside a microwave-safe container. Do not let the milk fill the container to its brim. It is important that you leave some space – about ¼th of the container – for the milk to rise when it boils in the microwave. Proceed to change the microwave’s temperature to a medium-high setting.  
  2. After the power has been set, allow the milk to sit in the microwave for about 1 minute. As the milk heats in the microwave, stir it at 15-minute intervals. The milk needs to be stirred so that its desired taste and texture won’t be altered.   
  3. Once the milk starts to get significantly hot, get ready to take it out. You should know that the total time taken for the milk to heat is dependent of the microwave you have. Some microwaves are more powerful than others – they heat food much faster. If your microwave has a high heating capacity, you’ll need to be more careful when heating milk.  

If you have larger quantities of milk to heat, you can either do it in 250ml batches or all at once. However, you’ll most likely need to experiment a bit if you wish to get the right microwave temperature and duration for heating your large batch of milk. 

Alternative Heating Methods 

If you don’t want to use a microwave for heating milk, you can make use of a pot. The pot of choice should be large and deep enough for the amount of milk you wish to heat. A large and deep pot is recommended because the milk tends to rise inside the pot as it is heated.

Pour the milk in the deep pot and place the pot on your stovetop. The best temperature for heating milk that’s intended to be drank warm or used in a sauce is medium heat. As the milk heats inside the pot, stir it at regular intervals – this prevents the milk from spilling over

What Happens if You Microwave Milk?

The microwave heats milk in an uneven manner that leads to the creation of dangerously hot areas that can burn one’s mouth. It is very important to pay close attention to milk being heated inside the microwave – failure to do so will cause the milk to spill over and get scorched.     

Does Boiling Milk Kill Viruses?

The process of boiling milk to kill bacteria is called pasteurization. This process involves boiling milk for about half a minute at 149⁰F. At this temperature and heating time, the vitamins and proteins contained in the milk won’t be destroyed. 

The nutrients found in milk are reduced when it is boiled at temperatures beyond 100⁰C for more than quarter of an hour. 

How Long Can Milk Sit Out?

Since milk is a perishable food, it cannot be left to sit at room temperature for more than 2 hours. Bacteria growth increases at room temperature and spoils perishable foods after exposure for more than 2 hours.
