It’s no surprise that in the past few years oat milk has really climbed in popularity for the plant-based milk of choice! It’s environmentally conscious using less water than almond milk (and traditional cows milk), and the taste is very similar to cows milk but sweeter.

Making oat milk at home is a great idea for avoiding gums and fillers too, which is traditionally found in store-bought brands for better shelf-life. But, I often hear that making oat milk at home results in a slimy texture! (Gross!).

Fortunately my recipe and method results oat milk with perfect taste and texture. There are a few special tips for achieving delicious vegan oat milk that’s not slimy!

So, let me share all the details for achieving perfect homemade oat milk every time.

The ingredients

The ingredients for this recipe are simple and straight forward. Likely, you already have them in your pantry.

For this recipe, you will need:

• oats
• water
• raw cashews
• coconut oil
• sea salt
• maple syrup

You might be surprised that this recipe includes more than just oats and water? Well, let me tell you that I recipe tested the heck out of this plant-based milk. And the additional ingredients adds lovely creaminess to your drink, and a smooth and silky texture. Certainly, if you’re looking for quality tasting homemade oat milk, this is your winning combo.

More on how these ingredients make for the perfect taste and texture to come.

How to make oat milk that tastes like Oatly and Earth’s Own

When it comes to oat milk brands on the market, no doubt Oatly is infamous for its taste and texture. It’s thick and creamy, full bodied, and smooth! I also really like Earth’s Own for the same characteristics.

Turns out, to achieve this creamy rich taste, we need a bit of fat in our milk.

Let’s take almond milk for example… Almonds have lots of natural fat. Which is squeezed out of the nut and into the milk when we make homemade almond milk. On the contrary, oats are low in fat. So, to achieve that same creamy, silky and smooth texture for a delicious milky drink; adding a little fat goes a long way.

Now, when we think of our favourite brands, like Oatly and Earth’s Own, it’s interesting to note their ingredients. In fact, the second ingredient in both these brands is rapeseed oil (Oatly) and sunflower oil (Earth’s Own). Betcha didn’t know that! I sure didn’t. But these brands realize that it’s the fat in the milk that offers better taste and consistency for a smooth, silky and creamy oat milk.

So, to achieve the same results for this homemade oat milk; I’ve opted in for a little fat; but healthier ones. Instead of rapeseed or sunflower oil, I’ve used raw cashews (a high fat and creamy nut) and bit of coconut oil. All-in-all it helps to achieve an ultra smooth and silky consistency, and an ultra creamy taste.

How to make oat milk that’s not slimy:

In a blender add oats, raw cashews, maple syrup, coconut oil, sea salt and water. Blend on high for no longer than 30 seconds.

Place your nut milk bag over a large bowl and pour oat blend into bag. Squeeze the bag to strain the milk from the pulp.

Pour the freshly squeezed milk from your bowl back into your blender (this allows for easy transfer into a bottle). Transfer the milk into an air tight bottle and store in the fridge.

Recipe Tips/FAQs:

This recipe is really easy and straight forward, but I have a couple IMPORTANT tips for achieving the perfect consistency for oat milk that’s not slimy. 

1. Don’t over-blend

“Why is my oat milk slimy!?” Now, this is common question regarding homemade oat milk. And it’s a problem I struggled with in the beginning of my recipe testing. My biggest tip to perfect your milk consistency (i.e. oat milk that’s not slimy) is to avoid over blending.

To make oat milk that’s not slimy; blend your ingredients on high for no longer than 30 seconds. You want the ingredients to be combined. But they don’t need to be 100% pulverized.

2. Don’t soak your oats

The second tip for making oat milk that’s not slimy: Don’t soak your oats. Soaking oats will also results in a slimy milk. I can assure you that I tried various combinations of soaking and rinsing, using both rolled oats and steel cut. In a nutshell, soaking my oats always resulted in slimy milk. So don’t do it.

My tip for making oat milk that’s not slimy and full of flavour is to use dry large flake oats. Without soaking.

How long does oat milk last in the fridge?

Oat milk will last in the fridge for up to 5 days.

Since there’s no stabilizers and additives, this milk has a shorter shelf life than store-bought versions. But whipping up a new batch takes only seconds. So even though the shelf life is shorter than store-bought, it really doesn’t cause much inconvenience. Plus, the pros of no additives, no fillers, gums or preservatives definitely outweighs this con.
