How To Defrost Frozen Milk

by Elizabeth Harding

Ever have a carton of milk that's been sitting at the back of the fridge for days that when you go to open it, it's still frozen? It happens to even the most careful of us. Well, this is your guide on how to thaw out a bottle of milk that's frozen solid.

Frozen milk (at least two days) has two methods of defrosting.

The first is the slow defrost by letting the carton sit in a bowl of room temperature water. It should take only 25-35 minutes for your milk to thaw and be ready to drink.

The other way is to put the carton in the microwave and heat it up slow. It works a lot faster. The issue is if the milk gets too warm, it will go through some chemical changes that can change the taste.

Is it Safe to Drink Defrosted Milk?

According to the USDA, it's safe to keep milk in the freezer for up to 3 months. Once defrosted at room temperature, you can drink milk. You can also put it back in the refrigerator as normal once opened i.e. you don't need to use it all at once.

Milk can be safe to drink even after it has been defrosted, only if the defrosted milk is stored in the fridge. One study1 found that the "total aerobic mesophilic count was 104 cfu/g of defrosted milk and the lactic acid bacteria (LAB) count was 1000 cfu/g of defrosted milk." In other words, bacteria counts were low enough that drinking defrosted milk was considered safe.

If you can't store your defrosted milk in the fridge, it is best to discard it rather than drink it.

Thawing Milk in the Refrigerator

To thaw frozen milk in the refrigerator, put the container into a bowl of cold water. Once you're happy that it's thawed out, shake the bottle of milk before consumption.
