The Ultimate Guide to Freezing Oat Milk: The Best Methods Revealed

Can You Freeze Oat Milk – The Best Way

Oat milk has become a popular choice among alternative milk drinkers due to its versatility and natural sweetness. It can be enjoyed on its own or used as a dairy milk substitute in a variety of recipes, including cream-heavy products like non-dairy ice cream. But what about freezing oat milk? Can it be done successfully? In this article, we will explore the best way to freeze oat milk and provide tips on how to thaw it without compromising its texture.

The process of freezing oat milk

Before we delve into the freezing process, it is important to understand how oat milk is made and why it freezes and thaws the way it does. Oat milk is made by extracting the moisture from oats, making it a good choice for people with food allergies or sensitivities, as it is naturally free of dairy, soy, nuts, and gluten.
To freeze oat milk, you have two options: freeze it in the carton or transfer it to an airtight, freezer-safe bottle. If the oat milk is unopened, you can put the entire carton in the freezer and it will last up to six months. However, if you choose to transfer it to a bottle, be sure to leave at least an inch of space at the top to allow for expansion during freezing. Label the date of initial freezing and avoid refreezing oat milk, which is not recommended.

Thawing Oat Milk

Proper thawing of oat milk is critical to maintaining its consistency and flavor. It is recommended that oat milk be thawed in the refrigerator rather than at room temperature. This keeps the milk cool and prevents the growth of harmful bacteria.
If you have frozen oat milk in the carton, simply remove it from the freezer and place it in the refrigerator. Allow it to thaw completely for at least eight hours or overnight before using. Once thawed, oat milk should be consumed within ten days.
Follow the same procedure for oat milk stored in freezer-safe bottles. Place the bottle(s) in the refrigerator and allow to thaw for eight hours or overnight. Thawing oat milk in the refrigerator overnight is especially convenient if you plan to use it in the morning. Consume defrosted oat milk within ten days.
It is important to note that oat milk may become slightly grainy after freezing and thawing. To reduce the graininess, you can strain the milk through a cheesecloth or nut milk bag. This will remove the tiny oat grains, resulting in a smoother texture. However, if you plan to use thawed oat milk in cereal or granola, you may not need to strain it, as the grainy texture will likely go unnoticed in these dishes.

Best Uses for Oat Milk

Oat milk is an excellent substitute for cow’s milk in a variety of recipes. While there are alternative milks for specific dishes, such as using coconut milk in curry, oat milk generally works well as a substitute for cow’s milk. Here are some of the best ways to use oat milk:

  • Replacing cow’s milk in cereals and granola
  • Creamer in coffee or latte
  • Base for smoothies, especially when combined with frozen bananas, nut butter and protein powder
  • Added to morning oatmeal for added flavor and creaminess

These are just a few suggestions, and the versatility of oat milk allows for experimentation in the kitchen. Feel free to explore different recipes and discover new ways to incorporate oat milk into your favorite dishes.

Benefits and Considerations of Freezing Oat Milk

Freezing oat milk has several advantages. First, it allows you to stock up on oat milk when it’s on sale or when you have an oversupply. Freezing also extends the shelf life of oat milk so it doesn’t go to waste. In addition, freezing oat milk is a convenient option for people who prefer to have it on hand for use in their favorite recipes.
However, it is important to consider the slight change in texture that occurs after freezing and thawing oat milk. The graininess that develops can be mitigated by straining the milk, but it is worth noting that the texture may not be exactly the same as fresh oat milk. However, many people find that the slight change in texture does not significantly affect their enjoyment of oat milk in various applications.


In conclusion, oat milk can be successfully frozen, providing a convenient way to store and preserve this popular dairy alternative. By following the recommended freezing and thawing methods, you can enjoy the benefits of oat milk for an extended period of time. Whether you use oat milk as a stand-alone beverage or as an ingredient in recipes, it offers a creamy and naturally sweet option that accommodates a variety of dietary preferences and restrictions. So freeze your oat milk with confidence, knowing you can enjoy its goodness whenever you need it.
