How to Freeze Milk

Have you ever been overwhelmed by a surplus of milk in your fridge and pondered, “Can I freeze this?” The simple answer is, “Absolutely!” Freezing milk is a practical way to extend its shelf life and reduce waste.

In this post, we’ll break down the process step-by-step, offering tips and tricks to ensure you get it right every time.

To freeze milk, first select a freezer-safe container, leaving space for expansion. Pour milk into the container, seal it tightly, label it with the date, and place in the freezer. To defrost, transfer it to the fridge, and remember to shake well before use. Frozen milk is best used within three months.

Why Freeze Milk?

Before diving into the nitty-gritty of freezing milk, let’s explore why you might want to do it.

Extending Shelf Life

Milk doesn’t last forever; typically, it remains fresh in the fridge for about a week after opening. By freezing it, you can extend its lifespan by up to three months. That’s quite a boost!

Properly storing milk is key when planning to freeze your milk. Learn how milk should be stored to maintain freshness before you freeze it.

Reducing Waste

When you freeze milk, you are effectively saving it for future use, rather than pouring it down the drain when it expires. This is a practical strategy to reduce waste, which benefits your wallet and the environment!

Choosing the Right Containers

One of the keys to freezing milk successfully is choosing the right containers. Here are some factors to consider:


Plastic jugs, glass jars, or even sturdy freezer bags can all serve as suitable containers for freezing milk. Just ensure they’re freezer-safe and well-sealed to prevent any potential leaks.


The container size you choose depends on your consumption patterns. If you’re likely to use a large amount of milk at once, larger containers may be preferable. But if you only need a little milk at a time, freezing in smaller portions is more efficient.

Container TypeProsCons
Plastic JugDurable, easy to sealMay not be reusable
Glass JarReusable, seals wellRisk of breakage needs space for expansion
Freezer BagEasy to store, flexiblePossible leakage, single-use
Ice Cube TrayConvenient for small portions, easy to useLimited volume, requires transfer to a freezer bag for long-term storage

The Freezing Process

Now that we’ve got the preliminaries out of the way, let’s dive into the freezing process.

  1. Pour the Milk into Your Chosen Container Leave some space at the top to allow the milk to expand as it freezes.
  2. Seal the Container Ensure the container is sealed tightly to prevent leaks and protect against freezer burn.
  3. Label the Container Write the date of freezing on your container. This will help you keep track of its shelf life.
  4. Place in the Freezer Finally, place your sealed and labeled milk in the freezer. It should be frozen solid in around 3-4 hours.

Making Milk Ice Cubes

Another handy way to freeze milk is to make milk ice cubes. This method is perfect for when you need just a small amount of milk, for instance, for your morning coffee or a smoothie.

Here’s how you can make milk ice cubes:

  1. Prepare Your Ice Cube Trays Make sure your ice cube trays are clean and dry. If you don’t have an ice cube tray, you can also use a silicone muffin tray or any other small, freezer-safe container.
  2. Pour the Milk Carefully pour your milk into the trays. Avoid filling the compartments to the brim, as the milk will expand as it freezes.
  3. Freeze the Milk Gently place the trays in your freezer. Wait for a few hours until the milk is completely frozen.
  4. Store the Milk Ice Cubes Once the milk ice cubes are fully frozen, you can remove them from the trays and transfer them into a freezer bag or airtight container for long-term storage. Make sure to label the bag or container with the date.

Using Milk Ice Cubes

Milk ice cubes can be a very convenient way to add a small amount of milk to your dishes and drinks. Here are a few ways to use them:

  • In Coffee or Tea: Drop a milk ice cube into your hot coffee or tea for a perfectly cooled and slightly creamy beverage.
  • In Smoothies: Add a few milk ice cubes to your blender when making smoothies for a creamy texture and added nutritional value.
  • In Cooking: When a recipe calls for a small amount of milk, you can simply drop it in a milk ice cube.
  • For Pets: If your pets enjoy milk, a milk ice cube can be a nice, cooling treat on a hot day (only if dairy is safe for your specific pet).

Remember, similar to frozen milk, milk ice cubes should be used within three months for the best taste and quality.

Defrosting and Using Frozen Milk

How to Defrost Milk

You can defrost frozen milk in the fridge or a bowl of cold water. In the fridge, it can take up to a day to fully thaw, while the cold water method can defrost milk in a few hours.

Shake It Up

Frozen milk can separate into water and milk solids. Give your milk a good shake after it’s defrosted to ensure these components are well-mixed before use.

When to Use Your Frozen Milk

Frozen milk is excellent for cooking, baking, or drinking. Here’s a quick list of uses:

  • Making pancakes or waffles
  • Preparing creamy soups or sauces
  • Whipping up a batch of homemade ice cream
  • Enjoying a cold glass with cookies or cake

How Long Does Frozen Milk Last?

Frozen milk is best used within three months. After this point, it can start to lose its fresh taste and nutritional value. It’s important to keep track of when you froze the milk to ensure you’re using it within this timeframe.
