How Do You Make Oat Milk?

We use milk every single day of our lives, from our morning granola to the bechamel sauce. Homemade Oat Milk is by far the cheapest and fastest plant-based homemade milk option.

We like that this recipe is super adjustable. You can make it creamier, sweeter or flavor infused.

Ingredients

It requires 2 ingredients, 5 minutes, and a blender.

• Rolled Oats
• Water
• Dates (optional)
• Salt (optional, omit if adhering to a Whole Foods Plant-Based diet)

Instructions

So, how Do you Get Milk from Oats?

The first thing you need to do, it put your oats to soak overnight in water. If you don't have the time and want to make it quick, you can also soak them in warm water for 5 minutes and proceed. I find that making them overnight gives the milk a creamier texture.

Remember to shop for Gluten-Free Oats if you are on a Gluten-Free diet, as Oats naturally do not contain gluten. Still, they are usually processed in places where there is gluten, and usually, they don't guarantee they are gluten-free.

You then need to drain the oats and add them to the blender. Blend for 1 to 2 minutes along with 4 cups of water.

You can optionally add a pinch of salt and your preferred sweetener or flavoring as for flavor enhancers.

Then it would be best if you strained through a nut milk bag or fine-mesh sieve lined with cheesecloth. Or even better, a clean t-shirt or canvas fabric bag, then squeeze out as much liquid as possible.

I like using a piece of fabric for Oat Milk because it is thinner, and that nuts milk, that way to strain more pulp out of it.

Suggested sweeteners: dates, raisins, agave syrup, or maple syrup.

Add in ideas: cocoa powder, vanilla extract, banana, strawberry, or hazelnuts.

Soaking your oats

• Soak the oats at room temperature or in the fridge.
• If a day has passed and you forgot or didn't get to make the oat milk, they are at room temperature, change the water, and put the soaking oats in the fridge. If you leave them longer, they will become gooey. In that case, we recommend placing them in a colander under running water for a couple of seconds before continuing with the process.
• If you need to make it the same day, pour warm water into the oats to accelerate the process and leave them soaking for 5 minutes.

Which type of oats?

We find that using Rolled Oats gives better results in general.

If you are on a Gluten-Free diet, look for rolled oats that clearly state it.

How to thicken It

This creamy oat milk recipe is already in the mid-range of thickness. If you want thicker milk, increase the amount of oatmeal.

We find the perfect thickness for our taste is 1 cup of oats / 4 cups of water.

Suggested thicker oat milk options:

• 1 cup of oats / 3 cups of water, if you don't mind sacrificing final volume.
• 1 ½ cups oats / 4 cups of water, if you want the same volume.

If you want thinner oat milk, reduce the number of oats flakes to ¾ cup or increase water by one cup.

Storing: how long does it last?

It depends on whether you sterilize your equipment and how fresh are the ingredients you used. In general, we have found it lasts about 2-3 days.

We use oat milk quite often for our morning smoothies or Homemade Granola, so one batch only makes it to the third day. If you are like us, you don't need to sterilize your ingredients as it reaches the 3^rd day without any problem.

If you find that it goes off before expected, easily sterilize your bottles either:

1. Pouring boiling water inside, ensuring the jars are not cold so that they won't break.
2. Then, putting them in the dishwasher.

If you have unexpectedly leave home or didn't use your milk soon enough and want to prevent it from going off.

You can freeze it in ice cube trays and save them to add to your morning smoothies.

Below are some recipes where you could use your oat milk:

• Easy Strawberry Banana Smoothie
• Vegan Cauliflower Wings

Does oat milk make you gassy?

If you are experiencing gassiness after consuming oat milk, there are a few things you could do to alleviate the symptoms. First of all, consider switching back to soy or almond milk. You may be particularly sensitive to oats so this might help quite a bit. The main issue with oat milk is that it contains oligosaccharides, a type of carbohydrate that is difficult for our bodies to digest because we lack the enzyme necessary to break them down.

Because oligosaccharides as well as other undigestible sugars travel through our digestive system whole, they end up feeding bacteria who produce gas in return.

This issue can be partially solved by thoroughly straining oat milk to remove the solids. If you experience a great deal of gassiness from drinking oat milk, try mixing it with another type of plant-based milk that is lower in oligosaccharides such as soy or almond.

Another trick is to add some additional ingredients such as ginger and chia seeds which help fight gas production. Although these products are not guaranteed to work for everyone, many people have reported relief from these changes.

Can oat milk make you nauseous?

The answers are yes, it is possible that oat milk could make you nauseous. It also depends on how much you drink and what other foods were consumed recently. Oat milk contains poly-unsaturated fats which are the building blocks of prostaglandins, which are lipid compounds that have hormone-like actions.

There are both beneficial and harmful prostaglandins in the human body. The negative ones can promote inflammation, intestinal cramps, diarrhea, nausea, etc., while the positive ones help reduce inflammation, lower blood pressure and ensure gastrointestinal tract health.

Does oatmilk have fiber in it?

Yes. Like other plants, oats contain fiber (or roughage), which is important for a healthy digestive system and maintaining a healthy weight. Oat fiber contributes to a feeling of fullness after consumption, making you less likely to snack between meals.

In fact, studies have shown that consumption of food containing high levels of viscous fiber/oats resulted in significantly reduced hunger ratings of the test subjects. Oat fiber also slows down carbohydrate absorption, which can help to regulate blood sugar levels and keep you feeling fuller for longer.
