What Are Oats?

Oats are healthy whole grains used in many healthy breakfast recipes to make overnight oats or pancakes using oat flour.

Oats have an amazing nutrition profile. It’s not only a high-fiber grain but also loaded with plant-based protein and is ideal for preparing fulfilling plant-based breakfast recipes.

Are Oats A Grain?

Yes, oats are considered whole grains. Oat kernel contains 3 different parts: the oat bran, the oat germ, and the endosperm.

In your local store, you can buy oats in 6 different forms:

  • Steel-cut oats
  • Rolled oats
  • Quick-cooking oats
  • Instant oats
  • Oat bran
  • Oat flour
different kinds of oats

What Is Oat Flour?

Oat flour is basically ground oats, flour made from old-fashioned oats or quick-cooking oats.

Most oat flour recipes use one or the other type of oats.

A few people use steel-cut oats that make an oat flour too high in fiber and, therefore very liquid absorbent.

How To Make Oat Flour At Home

It’s very easy to make oat flour at home. All you need is a blender or food processor.

Next, choose between rolled oats – also called old-fashioned oats – or quick-cooking oats.

Finally, add at least 3 cups of this ingredient to the high-speed blender and blend for about 45 seconds or until it turns into flour.

That’s it! You just made oat flour with one simple ingredient.

How to make Oat flour at home

How To Make Oat Flour From Steel-cut Oats

To make oat flour from steel-cut oats, you must use a high-speed blender.

In fact, steel-cut oats have a strong outer layer, and they won’t turn into oat flour in a food processor. Steel-cut also oats contain way more fiber than rolled oats.

So if you are making oat flour from steel-cut oats, it will be way more liquid absorbent than oat flour made from rolled oats.

It means that in a recipe that calls for oat flour, you may have to use only 1/2 cup of oat flour made from steel-cut oats to reach the same texture.

How To Store Oat Flour

You can store homemade oat flour in a sealed glass mason jar, in the pantry, or in the fridge for up to 6 months. 

You can also freeze oat flour in zipped bags and thaw it the day before using it.

Is oat flour healthy?

Frequently Asked Questions

Is Oat Flour Healthy?

Oat flour is a healthy flour made from oats, a whole grain high in plant-based proteins and fiber. Oat flour contains a high amount of soluble fiber that keeps the digestive system healthy and stabilizes blood sugar levels.

The nutrition fact for 100 grams (3.5 ounces) of oat flour made of rolled oats are:

  • Calories: 307 kcal
  • Protein: 11g
  • Carbs: 55g
    • Fiber: 8g
    • Sugar: 1g
    • Net carbs: 47g
  • Fat: 5g

In comparison, all-purpose flour contains only 10 grams of protein, 2 grams of fiber, and 76 grams of carbs per 100 grams.

It means that all-purpose flour spikes blood sugar levels faster than oat flour and doesn’t have the fulfilling properties of oat flour.

Does Oat Flour Have Gluten?

Oat is a naturally gluten-free grain but is often contaminated in the facility where it’s processed because it uses the same machine as wheat-based products.

So if you make oat flour from oats that the manufacturer guarantees as gluten-free, your oat flour will be gluten-free.

What Are Steel-Cut Oats?

Steel-cut oats are oat kernels without their bran that have been cut into two or three pieces.

It’s coarse in texture and must be cooked for a long time, about 30-40 minutes, to make a porridge. Steel-cut oats are the healthier version of oats, containing the most fiber.

What's steel cut oats

What Are Rolled Oats? Are Old-Fashioned Oats Rolled Oats?

Rolled oats are also called old-fashioned oats in some countries.

They are made from oats that have been steamed and flattened between rollers.

Rolled oats are great for making no-bake oatmeal bars or oatmeal breakfast bars. They have a chewy heartier texture than instant oats.

What's rolled oats

What Are Quick-Cooking Oats? Are Rolled Oats The Same As Quick Oats?

Quick-cooking oats are not the same as rolled oats. Like rolled oats, they have been rolled thinly and steamed, but quick oats are then cut into small pieces.

They cook faster than rolled oats or steel-cut oats, but they still have a good amount of fiber and high nutrition profile.

What's quick cooking oats
What are instant oats?

Instant oats are the highly processed version of oats, and consequently, they contain less fiber than rolled oats or steel-cut oats. It’s the one used in packaged oatmeal, often mixed with added sugar or flavoring.

Are oats gluten-free? Do oats have gluten?

Yes, pure oat kernels are gluten-free and safe for people intolerant to gluten. However, oats are often contaminated with gluten because it’s often processed in the same factory as wheat-based grains.
If you are gluten intolerant or celiac, choose certified gluten-free oats for your recipes.

What are oat brans?

Oat brans are the outer layer of the oat kernels. It’s removed in the process of making rolled oats or steel-cut oats. Oat brans are low in carbs, and since they contain mostly fiber, they are a keto-friendly oat ingredient for keto recipes.

How much oat flour equals regular flour?

In most recipes that call for oat flour, you can substitute oat flour for all-purpose flour with the same amount.
It means that 1 cup of oat flour can be replaced with 1 cup of all-purpose wheat flour or gluten-free flour blend.

Is oat flour keto?

No, oat flour is high in carbs and not keto-friendly. However, oat bran is keto-approved.

    Does store bought oat flour, such as Bob’s or Arrowood not work in baking recipes ? I already have a bag of each.

      Absolutely, they do work but it’s cheaper to make your own using this tutorial.

    Can I use Gerber organic oatmeal instead? I have it and my son hates it. So I’m thinking of using it as oat flour to make teething rusk

      I checked online and it seems to be 100% made of wholegrain oat flour so it should work in any recipes calling for oat flour! Keep me posted! XOXO Carine
