This homemade oat flour recipe is a simple, beginner-friendly way to make healthy flour using just instant oats. All you do is lightly toast the oats to release a nutty aroma and then blend them into a fine powder. The result is soft, fiber-rich flour that’s great for smoothies, chapatis, or even thickening curries. I always keep a jar ready, it’s fresh, clean, and far better than store-bought versions. So if you’ve got a packet of oats sitting in your pantry, give this a try, it hardly takes 5 minutes! Perfect if you're cutting down on refined flours or want a nutritious twist in daily meals.

About Oat Flour
Oat flour is something I always keep ready in my kitchen. It's so easy to make at home, and I prefer this over buying from the store because I know it’s fresh, clean, and made with no additives. Honestly, it's just instant oats ground up, but the uses are endless.
I use this homemade oats flour in so many ways: to thicken curries, mix into roti or paratha dough, or even in baking. Sometimes I just add a spoonful to my smoothies in the morning for an energy boost. I especially remember doing this during exam days when I didn’t feel like eating much but needed something wholesome.
What I love is that this recipe is beginner-friendly. You don’t need any fancy equipment, just a dry pan and a blender. If you can spare five to seven minutes, you can make a small batch and store it for later. So handy and fuss-free!

Why This Recipe Works
This recipe works so well because it's honestly one of the easiest things you can do in your kitchen. All you really need is regular instant oats or rolled oats, and a blender. That’s it. Nothing fancy, no big prep. Toasting the oats just for a minute or two before blending really makes a difference. It gives the oats a light nutty aroma and makes the flour smoother, which helps especially if you’re using it in baking or chapati dough.
Why I Love This Recipe - I like this recipe because it’s honestly so effortless and fits into my daily routine without any fuss. On busy mornings when I don’t feel like eating much, I just whip up a quick smoothie and toss in a spoonful of this oats flour, it makes it thicker, keeps me full for hours, and gives that extra bit of nutrition without any effort.
Another reason I keep coming back to this recipe is that oats are naturally gluten-free. Just make sure to pick oats that are certified gluten-free if you're making it for someone with a gluten intolerance or celiac. It’s also incredibly versatile. I’ve used this oat flour in muffins, pancakes, smoothie bowls, and even to thicken soups and curries. It blends in so well and adds that mild taste and extra nutrition.
What I also love is how I can add it to everyday meals without anyone really noticing. I mix it into roti dough, or even add a little when I’m making sabzi or curry to make the gravy slightly thicker and more wholesome. It doesn’t change the taste much, which is perfect when cooking for picky eaters.
Ingredients
1 cup Instant Oats – I use instant or rolled oats, the regular kind available in most kitchens. It’s best to use plain, unflavored oats. One cup gives you approximately ¾ to 1 cup of flour, depending on how finely it’s blended.
No other ingredients! – That’s the beauty. You don’t need anything else. If you want to level it up, you could mix in a pinch of cinnamon or flaxseeds for extra nutrients, but even plain is great.
Hacks
1. Toast for Better Taste and Storage
Toasting oats for just 2–3 minutes in a dry pan really brings out a warm, nutty aroma. It also helps remove any raw flavour and makes the flour less sticky when stored. Plus, this step improves the shelf life by reducing moisture in the oats.
2. Blend in Batches for a Smooth Texture
If you want really fine flour, don’t overcrowd your blender—blend in small amounts. This gives the blades enough room to work properly and avoids overheating. You’ll end up with a soft, even powder that mixes better in recipes.
3. Combine with Other Flours
When using oats flour in rotis or baking, try mixing 1 part oats flour with 2 parts wheat or maida. Oats alone don’t have gluten, so this mix gives the dough better structure and stretch. It also makes rolling easier and keeps the final dish from falling apart.
4. Add as a Natural Thickener
Need to thicken a curry or soup quickly? Just stir in 1 spoon of oats flour and simmer for 2–3 minutes. It blends in smoothly and gives a creamy texture without changing the flavour. This is an easy trick I use when I want to skip corn flour or maida.

Expert Tips
Storage
Keep your oats flour in a clean, dry, and airtight container. If you’re going to use it within a few days, storing it at room temperature is fine. But if you want to keep it fresh for 2–3 weeks or longer, store it in the fridge, it stays bug-free and maintains its taste and texture. I store the powder in a small airtight container or jar and keep it in the fridge if I’ve made a bigger batch. That helps it stay fresh and prevents any bugs or moisture. Usually, I make just enough to last me 7–10 days.
Serving Suggestions
There are lots of easy ways to use this flour daily. Add a spoon to your morning smoothie to make it more filling, or mix it into paratha or chapati dough for extra fiber. It’s also great in baking, try adding it to banana bread, muffins, or cookies for a wholesome touch. You can even make quick oats pancakes by mixing it with curd, chopped veggies, and a pinch of salt.
Quick Fixes
If the flour feels lumpy after storing, just stir it with a spoon or re-blend for a few seconds to make it smooth again. When making rotis, a good mix is 1 part oats flour to 2 parts wheat flour, this helps keep them soft while adding a bit of extra nutrition. If your dough feels too dry, just add a spoonful of curd or water to bring it together smoothly.
FAQ
Can I use rolled oats instead of instant oats?
Yes, definitely! Rolled oats work just fine for this recipe.
They might take a few seconds longer to blend into a smooth flour, but the texture and result are pretty much the same. So if you’ve got rolled oats at home, go ahead and use them, no need to buy something new.
Can I skip the toasting step?
Technically, yes, you can skip it. But toasting helps in a few ways: it brings out a light nutty flavor, removes any extra moisture, and helps the oats blend more easily. It only takes a couple of minutes, and it really makes the flour better overall. So if you have the time, I’d say go for it.
How much flour does 1 cup of oats make?
If you start with 1 cup of oats, you’ll end up with around ¾ to 1 cup of oats flour, depending on how finely you grind it. The more you blend, the finer the flour becomes, just make sure not to overdo it, or it can get clumpy.
Can I use this in place of wheat flour for baking?
You can replace part of the wheat flour like 25% to 30%, in baking recipes with oats flour. It adds a bit of extra fiber and a soft texture, especially in things like muffins or banana bread. But don’t swap out all the wheat flour unless the recipe is made specifically for oats flour, because it affects how the baked item holds together.
Variations
Oats-Almond Flour Mix - Want to give your oats flour a protein boost? Just add about ¼ cup of almonds along with the oats while blending. The almonds add a nice nutty richness and make the flour great for baking cookies, muffins, or even energy balls. It also keeps you full for longer.
Flax Oats Flour - Toss in 1 tablespoon of flax seeds before grinding the oats to boost the fiber and omega-3 content. This mix is especially good for breakfast recipes like smoothies, pancakes, or even overnight oats, healthy and filling!
Flavored Oats Flour - If you're planning to use the oats flour for sweet dishes, blend in a pinch of cinnamon or cardamom. It adds a subtle flavor that works really well in baking and sweet snacks, without needing any extra sugar or additives.
Savory Mix
Looking for a version that fits well with Indian-style dishes? Add a few dried curry leaves or mint leaves before blending. It creates a lightly herby flour that tastes great in rotis, dosas, or cheelas and saves you time while cooking.

Ingredients
- 1 cup Instant Oats
Instructions
- Pre-Prep: First measure out 1 cup of instant oats. You can double or triple the batch, but I like making small amounts so it stays fresh. Then, heat a dry pan and lightly toast the oats for just 2–3 minutes. It shouldn’t get too brown, just a mild nutty smell is perfect. This step removes moisture and gives a nice aroma.
- Blending into Flour: Once the oats are cool (after toasting), add them to a clean, dry blender jar. Pulse it a few times until it becomes a fine powder. You can sieve it if you want an extra smooth texture, but I usually skip that unless I'm using it for baking.
