How to make oat milk
Whether you're dairy-free or not, you may be interested in making your own homemade oat milk.
Simply blend together rolled oats, water, sweetener of choice, and salt for a quick and easy plant based milk.
I love blending my DIY oat milk together on a Sunday or Monday and using it throughout the week. I store mine in a pitcher or large mason jar to lock in freshness!
Oat milk should last 5-7 days, when stored well-sealed in the refrigerator.
It's normal for homemade dairy free milk to separate. Just give it a stir before drinking!
Tips for making homemade oat milk
Here are a few things to keep in mind when making oatmilk:
- For gluten free oat milk, use certified gluten-free oats.
- Be sure not to over-blend, as that can lead to slimy oat milk!
- Change up the sweetness and flavor depending on your personal preferences.
Unfortunately, homemade oat milk does not froth well because it does not contain a lot of protein or fat to form air bubbles.
Yes, you can freeze oat milk for up to 3 months. The defrosted oat milk should be used within 3 days of thawing. Even though you can freeze oat milk, I recommend against it since the grains separate during the freezing process.
If needed, you can warm oat milk in the microwave in short increments. If you heat it too quickly, it can become very thick.
Yes, store oat milk in a sealed container in the fridge for up to a week. You'll notice it's gone bad when it has a funky smell and unpleasant taste.
