Can You Freeze Oat Milk? Find Out Here

Oat milk has become a popular alternative to dairy milk in recent years. It’s rich, creamy, and has a mild flavor that goes well with most foods. If you’re a fan of this plant-based milk, you may be wondering, can you freeze oat milk?

The answer is yes. If you want to make sure that your oat milk stays fresh for a long time, then freezing it is the best option.

This article will help you understand what oat milk is, how to freeze it, how long you can freeze it, etc. Let’s get started.

What Is Oat Milk?

Oat milk is a non-dairy milk alternative made from oats (hence the name). The most common way to make it is by blending oats, water, and natural sweeteners until smooth.

Oat milk is rich in vitamins such as A, B6, and E, which help build immunity against diseases like cancer and heart disease. It also contains minerals such as calcium, magnesium, and potassium, which keep your bones strong.

Oat milk has a mild flavor and a creamy texture, so it’s great in smoothies, cereals, or baked goods. You can also drink it on its own or use it as an ingredient in savory dishes like soups and stews.

This plant-based milk is available at most health food stores, as well as most grocery stores such as Trader Joe’s and Whole Foods. It’s also easy to make at home using an oat milk maker or blender.

Can You Freeze Oat Milk?

Yes, you can. Freezing your oat milk will make it last longer than leaving it in the fridge. It’s also cheaper than buying new cartons every week.

The only downside is that freezing can change the texture and consistency of the milk so that it’s not as creamy or smooth when thawed as when fresh.

To avoid this, make sure the texture of the milk is good before freezing it. If it’s too thick and creamy, it could separate when thawed. If your oat milk is too thin, it won’t freeze well either.

Also, if you’re planning to freeze your milk for a long time, then I highly recommend adding an acidic ingredient such as lemon juice or vinegar to it before freezing. Adding it will help preserve all the nutrients in your milk for long-term storage.

Why Should You Freeze Oat Milk?

Oat milk is more susceptible to spoilage than other non-dairy milk like almond and soy milk. This is because the high water content present in oat milk makes it more prone to bacteria growth and spoilage.

However, by freezing oat milk, you will preserve its freshness and prevent any bacterial growth that could occur if left at room temperature for too long. It is a great way to save money on your grocery bill and help the environment by reducing waste.

Freezing oat milk also allows you to buy large quantities at once instead of having to buy smaller batches every day or week. This is especially helpful if you’re buying oat milk for your baby since babies’ tummies can only handle small amounts of food at a time before they get full or gassy.

How to Freeze Oat Milk

In an airtight container

  • Pour your desired amount of oat milk into an airtight container and seal tightly. This is important because any air in the container could cause bacteria growth or freezer burn.
  • Label the container with the date and contents so you can easily identify it later.
  • Put the container into an airtight freezer-safe bag, then place the bag in the freezer. This will help prevent freezer burn and maintain optimum quality over time.

In an ice cube tray or silicone mold

  • Pour the oat milk into an ice cube tray or silicone mold.
  • Make sure each cube has enough room for expansion.
  • If using silicone molds, allow them to sit in the freezer for 15 minutes before adding the milk to help prevent spills when you’re pouring it in.
  • Freeze overnight, and then transfer the frozen cubes into a freezer-safe container with an airtight lid.
  • Mark your container with its contents and date so you can easily identify it later.

How Long Can You Freeze Oat Milk?

Commercial oat milk
