Learn how to make oat flour at home with and without a blender or a food processor! We’ll also take a look at a few recipes to help you use the flour you made out of oats! Making oat flour might seem like a huge undertaking, but honestly, it’s a super easy process and takes about 5 minutes.
Can we just establish that by now nobody doubts the nutritional benefits of oats? They are the main ingredient in many healthy recipes and all healthy-eating fans undoubtedly have them in their kitchen cupboards.
But have you ever wondered how to make oat flour at home? And especially whether or why you should even bother? In short – you can, you should and it’s super easy!
7 Good Reasons To Make Oat Flour
Now, before we get to our oat flour making tutorial, let’s take a look at a few reasons why it’s good to do it in the first place:
- It’s cheaper. Who knew that the very act of grinding your food can make it more expensive? Well, it does!
- You know what’s in it! “Trust no one” is my life’s motto. Just kidding. Kinda. But not really, because when it comes to food there are things labeled healthy and then something comes out and you’re disappointed. When you at least can see what’s inside your meal – you know for sure.
- Has a neutral taste suitable for all kinds of dishes. The flour made out of oats has a neutral taste, unlike most nut flours (such as almond, coconut, etc.). This makes it suitable for incorporating into a variety of dishes – from starters and main courses to desserts.
- Takes less space for storage. Basically, oats reduce their size when ground. This may be of importance in case you are short of space. I don’t know about you – but I love having space in my pantry!
- Is gluten-free. If the oats you use to make flour are certified gluten-free, then your oat flour will be gluten-free as well. This makes it especially suitable for people with celiac disease, who need to stick to a gluten-free diet.
- Retains all the nutritional value. When you grind oats to make oat flour, all the nutrients are retained. In other words, the flour is just as healthy and nutritious as the oats themselves. Also, when you make it yourself – you know how long it’s been sitting there in your cupboard. In general, foods like oats, flaxseed, almonds and chia seeds have more antioxidants when they’re whole. When you grind them (as you’ll do to get flour) – these foods oxidize faster, which reduces their shelf life. If you get it at the store the flour might have been sitting there for years. When you make your own – you can use it up within a few weeks and make a fresh batch after you’ve run out of it. It literally takes 5 minutes.
How to Make Oat Flour?
Although you may not believe it, there’s nothing simpler than that! Just follow this step-by-step guide on how to make oat flour and it will be ready in a matter of minutes.
In A High-Speed Blender
Firstly, pour some oats into your blender. You can use both rolled and quick oats, it doesn’t really matter. However, rolled oats may take a little more time to grind.
Blend until the oats have turned into a fine powdery flour. The process should take as long as 30 seconds, maybe up to 1 minute, depending on your blender.
That’s all! Yes, as easy as that.
In A Nut Or Coffee Grinder
Now, if it can grind nuts and coffee, then that little thing surely can grind oats as well. And it does. So if you have a coffee grinder – use it to make your very own oat flour. In my experience, this is the best way to grind oats. Simply put your oats in it and pulse until they’re very finely ground – using mine it takes about 30 seconds. It could vary, depending on the coffee grinder you’re using.
Can You Make Oat Flour In A Food Processor?
Yes! But, as I’ve found out, it won’t be as fine as the oat flour you make in your blender or nut/coffee grinder. This method will mostly work for bigger batches of oats.
How to Store
Once your flour is ready, you will need to store it properly. As a result, you will not only preserve its quality but also prevent deterioration for as long as possible. Here I am sharing three methods that you can use to store your flour. Choose the one that best suits your needs:
- Firstly, put your oat flour in a sealed plastic bag, an airtight container, or a large mason jar. Store it in a cool place either in your pantry or kitchen cupboard for up to 2 months.
- If you have some spare space in your refrigerator and intend to keep the flour for longer, then you can store it there for up to 4 months.
- And finally, if you prefer the freezer, your flour will be good enough for up to a year.
