Is It Safe to Heat Milk in Microwave?
We’ll start by easing your fears about the safety of heating milk in the microwave. It is perfectly safe to nuke milk assuming that we aren’t talking about breast milk.
Breast milk should never be microwaved as it can change the composition of the milk, and also, can develop hot pockets that can scorch your baby’s mouth.
Outside of these parameters, warming milk in the microwave is a safe practice.

Heating Milk in Microwave Cancer
It is possible that you’ve heard rumors about microwaving milk causing cancer. At this point in time, there is no strong evidence that would suggest that drinking milk of any sort causes cancer. In fact, there are several studies that seem to show quite the opposite.
There is, however, a chance that the nutritional value of milk is lowered once it hits its boiling point. For this reason, you may wish to limit the number of times you choose to boil your milk.
How Do I Warm Milk in the Microwave?
Now that you know that warming milk in the microwave won’t hurt your health, it’s time to talk about how you can properly warm milk without it curdling or exploding in the microwave.
To gently warm milk, try the following:
- Select a microwave-safe cup or bowl to place your milk in.
- Pour the desired amount of milk into the cup.
- Lay a single paper towel over the cup or bowl to encourage even heating and to prevent the milk from splattering. Make sure the paper towel is not bunched, and that it lays straight.
- Microwave your milk for 10 seconds.
- Carefully remove the milk and stir.
- Place the milk back in the microwave and heat for another 10 seconds.
- Remove, stir, and test for warmth. Continue to heat the milk at 10-second intervals until it reaches the desired level of heat or has steam emitting from the top.
Note: It’s important to use a microwave-safe paper cup, glass bowl, or container. Containers or cups not specifically designed for use in the microwave run the risk of leaching harmful chemicals into your food. Containers not meant for use in the microwave may even catch fire!
How Long to Heat Milk in Microwave?
Heating your milk in the microwave should be done at intervals of about 10 seconds at a time until the milk reaches the desired temperature. When heating milk too long, you run the risk of scorching it, causing it to explode, or causing it to develop an unappetizing film on top.
Heating Milk Microwave vs Stove
When comparing the process of heating milk in the microwave to the stove, it really is a matter of convenience and preference. Of course, you can expect milk heated on the stove to take a bit longer to warm than milk in the microwave.
Some people also believe that milk warmed on the stove tastes better than milk in a microwave, but of course, taste in this context is very subjective!

How to Heat Milk in the Microwave: It’s Easy!
Heating milk in the microwave is very easy provided that you do it the right way. To prevent scalding, exploding, or an icky film on top of your milk, be sure to heat it only at intervals of 10 seconds at a time before giving it a good stir and warming it again.
We hope it helps!
FAQ
How can I microwave milk without curdling?
Heat milk at intervals of 10 seconds and stir between breaks to avoid curdling and separation.
Why can’t you heat milk in the microwave?
You can heat milk in the microwave, but doing so may slightly lessen the nutritional value of the milk. We also recommend against microwaving baby formula and breastmilk, as doing so may cause hot spots to develop in the milk.
Why does milk explode in the microwave?
An explosion is a natural reaction to too much steam being generated within a liquid. Thus, splattering milk is the result of milk that has been heated too long.
Can you microwave milk?
Milk can be microwaved as long as you do so carefully to prevent scorching and overflow.
