One of the main reasons to freeze oat milk is for longevity. Homemade oat milk only lasts a couple of days in the fridge, while store-bought oat milk has a slightly longer shelf life.

How to Freeze Oat Milk: A Step-by-Step Guide

Freezing oat milk is pretty straight-forward. You have different methods that can be used and I will not look at each on in detail.

  • Freezing oat milk as ice cubes

Freezing Oat Milk in a Ice Tray

The advantage of freezing oat milk in an ice tray is that you can take out how many cubes you need and don’t have to worry about defrosting the whole container or carton.


  1. Start by pouring your oat milk into an ice tray.
  2. Place the ice tray in the freezer and let it freeze for several hours or overnight.
  3. Once the milk is frozen, remove the cubes from the ice tray and place them in a freezer-safe container or bag.
  4. Label the container or bag with the date and place it back in the freezer.
  5. To use, simply remove the desired number of cubes from the container and add them to your smoothie or recipe.

Freezing A Carton of Oat Milk

If your favorite brand of oat milk (like Oatly) comes in a carton, then you can freeze the whole carton.

While the milk will expand as it freezes, you should not worry too about the carton bursting open, but to be on the safe side, it is always a good idea to pour a bit of milk out before freezing.


  1. Pour out about ½ inch of milk from the top of the carton to allow for expansion.
  2. Place the carton in the freezer and let it freeze for several hours or overnight.
  3. Once frozen, you can leave the milk in the freezer till you are ready to use it.

Freezing in a Freezer-Safe Container

The advantage of freezing in a freezer-safe container is that you can portion out how much oat milk you want to freeze. This can be helpful if you only use oat milk occasionally and don’t want to have to thaw an entire carton or container at once.


  1. Start by pouring your oat milk into a freezer-safe container.
  2. If you are using a glass container, make sure to leave some room at the top for expansion.
  3. Place the lid on the container and label it with the date.
  4. Place it in the freezer and let it freeze for several hours or overnight.
  5. To use, simply remove the desired amount of oat milk from the container and thaw it in the fridge or use it directly from the freezer in smoothies or baking recipes.

Thawing Frozen Oat Milk

Frozen oat milk will last for up to 3 months in the freezer, but it is best to use it within the first month or two for the best quality.

When you are ready to use your frozen oat milk, simply remove it from the freezer and thaw it in the fridge overnight.

You can also let it sit out at room temperature for a couple hours to defrost.

Once thawed, give the milk a good shake or stir before using.
