What Are the Three Ingredients in Oat Milk? The Simple Homemade Recipe

4 min read

In 2022, oat milk's mainstream popularity was cemented when it was officially added to the Merriam-Webster dictionary, highlighting its rise as a plant-based staple. For those seeking the purest form without commercial additives, the answer to what are the three ingredients in oat milk is surprisingly simple: oats, water, and a pinch of salt.

Quick Summary

The most basic homemade oat milk recipe uses just three components: rolled oats, water, and salt. While store-bought versions often include additional ingredients for texture and fortification, making it at home is straightforward and requires minimal fuss for a fresh, creamy result.

Key Points

  • Three Simple Ingredients: Basic homemade oat milk requires only oats, water, and a pinch of salt.

  • Use Rolled Oats: For the best, creamiest texture and to avoid sliminess, use old-fashioned rolled oats, not instant or quick-cooking varieties.

  • Cold Water is Crucial: Using ice-cold water during blending helps prevent the release of starch that causes a gummy texture.

  • Blend Briefly, Strain Gently: Over-blending and squeezing the oat pulp during straining are the primary causes of slimy oat milk.

  • Homemade vs. Commercial: While homemade is simpler and additive-free, store-bought oat milk often contains added oils, stabilizers, and fortifications not present in the basic version.

  • Customizable Flavor: After straining, you can add sweeteners like maple syrup or flavors like vanilla extract to customize your oat milk.

  • Nutritional Value: Fortified commercial oat milk can be an excellent source of calcium, vitamin D, and B vitamins, though homemade versions rely on the natural nutrients of the oats.

Understanding the Core: What Are the Three Ingredients in Oat Milk?

At its heart, the process of making oat milk is a masterclass in culinary simplicity. Stripping away the additives and stabilizers found in many store-bought cartons reveals a clean, pure beverage made from just three fundamental ingredients. These are the building blocks that, when combined correctly, create a creamy, mild-tasting plant-based milk alternative.

The Three Foundational Ingredients

1. Oats

The most important ingredient, of course, is the oats. For the best texture and flavor, old-fashioned rolled oats are the most recommended variety. Their processing allows them to blend and break down effectively without becoming too slimy. In contrast, quick-cooking or instant oats tend to produce a more viscous, gummy result due to their finer state, and steel-cut oats don't blend into a smooth enough consistency. Always choose high-quality, rolled oats for a superior homemade milk. If you require a gluten-free diet, ensure your oats are certified as such to avoid cross-contamination from other grains processed at the same facility.

2. Water

Water acts as the liquid base that transforms the solid oats into a drinkable milk. The key to a non-slimy, fresh-tasting oat milk lies in using ice-cold, filtered water. The cold temperature helps prevent the oats from releasing too much starch, which is the primary cause of the undesirable gelatinous texture. The ratio of oats to water is also critical, with a common starting point being a 1:4 ratio (one part oats to four parts water).

3. Salt

While optional, a small pinch of sea salt or pink Himalayan salt is a highly recommended third ingredient. It doesn’t make the milk taste salty but rather helps to enhance and balance the natural nutty and slightly sweet flavor of the oats. It brings all the flavors together, much like salt in baking, to create a more well-rounded and palatable final product.

Step-by-Step Homemade Oat Milk Recipe

Making oat milk at home is a quick process that takes just a few minutes. Following these simple steps will help ensure a creamy, delicious result.

Ingredients:

  • 1 cup old-fashioned rolled oats
  • 4 cups cold, filtered water
  • Pinch of salt

Instructions:

  1. Combine Ingredients: Add the rolled oats, ice-cold water, and a pinch of salt to a high-speed blender.
  2. Blend Briefly: Pulse the mixture for no more than 20 to 30 seconds. This is crucial for avoiding a slimy texture. A brief blend is all that’s needed to break down the oats and infuse the water with their flavor.
  3. Strain Immediately: Place a nut milk bag or a clean, thin t-shirt over a large bowl and pour the blended mixture into it. Allow the liquid to drain naturally through the bag. Do not squeeze the bag, as this forces the starch out of the pulp and results in a slimy mouthfeel.
  4. Store and Shake: Pour the strained milk into an airtight container or mason jar. It will keep in the refrigerator for up to five days. Since homemade oat milk contains no stabilizers, some separation is normal. Simply shake well before each use.

Homemade vs. Commercial Oat Milk: A Comparison

Feature Homemade Oat Milk Commercial Oat Milk (e.g., Oatly)
Core Ingredients Oats, water, salt. Oat base (water, oats), plus several additives.
Additives None, unless you add optional sweeteners or flavors. Often contains low erucic acid rapeseed oil (for creaminess), dipotassium phosphate (acidity regulator), gellan gum (stabilizer), etc..
Nutritional Fortification None. Nutrients are from the oats themselves. Fortified with vitamins A, D, B12, and calcium to mimic dairy's profile.
Texture Generally thinner and fresher-tasting. Thicker, creamier, and more consistent due to additives. Formulated for specific uses like frothing.
Shelf Life Lasts 3-5 days refrigerated. Long shelf life, often shelf-stable until opened.
Cost Much more affordable per serving. Higher cost per serving.

Customizing Your Three-Ingredient Oat Milk

While the basic recipe is delicious on its own, it’s also a perfect canvas for customization. Once you have strained your milk, you can add extra ingredients to taste.

Flavorings and Sweeteners:

  • A teaspoon of vanilla extract or a dash of cinnamon can add warmth and depth of flavor.
  • For sweetness, consider adding a date or a tablespoon of maple syrup during the initial blending stage.

Adding Nutrients: If you want to add more nutrients to your homemade version, consider blending in a couple of pre-soaked macadamia or cashew nuts. This can increase creaminess and nutritional value without adding a strong nutty flavor.

The Health Benefits of Oat Milk

Beyond its simple ingredient list, oat milk offers a number of health benefits, especially when it's fortified. Oats are a great source of soluble fiber, which is known to lower LDL (or "bad") cholesterol. Fortified versions, like many commercial brands, can be an excellent source of essential nutrients such as vitamin D, calcium, and B12, which are crucial for bone and nerve health. This makes it a great choice for those on a vegan or dairy-free diet who may need to supplement these nutrients.

Conclusion

In summary, the foundational answer to what are the three ingredients in oat milk is oats, water, and salt. While commercial products expand this list for stability and fortification, creating a pure, simple version at home is a rewarding and cost-effective endeavor. By carefully choosing your oats, using cold water, and blending for just the right amount of time, you can achieve a creamy, fresh-tasting plant-based milk with minimal effort. Whether you prefer the simplicity of the homemade version or the convenience of a store-bought, fortified carton, oat milk remains a popular and versatile dairy-free alternative with a wholesome, grain-based origin.
