Cassava flour is the whole peeled root, dried and milled into a mild powder that bakes more like wheat than any other gluten-free flour. Getting it right depends on careful peeling, thorough drying, and patient sieving, from farm to bag.
I make flour in batches of about three kilograms in Abia State, Nigeria, using roots from my own harvest.
The cubes dry in my oven, a blender mills them, and every batch passes through three sieves.
I bake chin-chin and buns with that flour, and one two-kilogram pack stayed in good condition for a full year.
This pillar brings together what I have learned firsthand with published standards and research.
It covers how the flour differs from tapioca, the main types, and the production methods.
Safety, health basics, cooking uses, buying, and storage follow, with links to deeper guides throughout.

What Is Cassava Flour?
It is the whole cassava root, peeled, dried, and milled, so it keeps the root’s fiber, sugars, and minerals.
Tapioca is different, because it contains only the starch washed out of grated roots, leaving the fiber behind.
The root itself, from varieties to cooking, is introduced in the guide asking what cassava root is.
Tapioca has its own hub explaining what tapioca is, and the two are compared in the article on flour versus tapioca starch.
Garri is not flour either, since it is fermented, pressed, and roasted into coarse granules rather than milled fine.
Where the Flour Comes From
Cassava originated in South America, and its long journey to Africa and Asia is traced in the history of the mandioca plant.
Nigeria grows more cassava than any other country, yet most Nigerian roots still become garri, fufu, and starch rather than fine flour.
Variety affects cyanide levels and processing, as the guide to bitter versus sweet cassava sets out.
Types of Flour Made From Cassava
| Type | How it is made | Typical uses |
|---|---|---|
| High quality flour (HQCF) | Peeled, grated or chipped, dried quickly without fermenting | Bread blends, confectionery, glue |
| Fermented flour (lafun) | Roots soaked and fermented before drying and milling | Swallow such as amala lafun |
| Modified flour | Fermented or treated to change baking behavior | Breads and snacks |
| Organic flour | Grown and processed under certified organic rules | Grain-free and paleo baking |
A 2017 study in LWT Food Science and Technology analyzed high quality flour made from 45 different cassava genotypes.
The quick, unfermented grade is explained in the guide to high quality flour (HQCF).
Wikipedia’s amala entry notes that fermented lafun makes amala lafun, a Yoruba swallow.
Treated grades are described in the article on modified flour and mocaf.
Under USDA organic rules, synthetic fertilizers, sewage sludge, irradiation, and genetic engineering may not be used.
Certified organic brands sold in the United States are compared in the guide to the best US flour brands.
How Cassava Flour Is Made
- Harvest mature roots and process them within a day or two, before they start to spoil.
- Peel off both the brown skin and the thick inner layer, then wash the peeled roots in clean water.
- Cut the roots into small cubes or chips, or grate them, so they dry quickly and evenly.
- Dry the pieces until they snap cleanly, using sun, a dryer, or an oven on gentle heat.
- Mill the dried pieces into powder, then sieve out the coarse fiber and re-mill it if needed.
- Cool the flour completely, then pack it in airtight bags away from moisture and light.
In my kitchen, half-inch cubes go into the oven until they show a uniform color and break with a brittle snap.
I peel before washing, then give the roots one basin wash and a single rinse in borehole water.
An ASARECA and IITA quality manual sets dried chips at 12 percent moisture or below before milling.
The same manual targets fine flour particles of 250 to 500 microns.
Step-by-step methods appear in the guides to producing flour at home, the traditional flour-making method, and the fermentation method.
Factory lines are covered under the industrial production method, with mills compared in the guide to the flour milling machine.
Health Basics
It is mostly starch with little protein, so it supplies energy far more than building material.
An IITA study of Nigerian staples measured eba at a glycemic index of 88 to 99, firmly in the high range.
The flour contains no gluten, and US labels marked gluten-free must stay below 20 parts per million.
Lab composition, glycemic data, and who should take care are covered in the full flour nutrition breakdown.
Diet-specific questions have their own answers in posts on keto and low-carb plans, low FODMAP eating, and the Whole30 program.
Further questions are answered for AIP diet followers, lectin-free plans, low-oxalate diets, and low-histamine eating.
Safety Standards
The Codex standard for edible flour caps moisture at 13 percent, crude fiber at 2 percent, and ash at 3 percent.
Codex also limits hydrogen cyanide in this flour to 10 milligrams per kilogram, as FSANZ records in its review.
Peeling, cutting small, and drying thoroughly all lower cyanide, which the post asking does the flour contain cyanide examines.
Heavy metal concerns raised online are reviewed in the article on flour and lead poisoning.
Cooking and Baking Uses
The flour behaves more like wheat than nut or coconut flours, though it absorbs more liquid.
Culinary scientist Jessica Gavin suggests starting with about 2/3 cup for every cup of wheat flour.
Tested recipes are gathered in the flour recipes collection, from soft bread rolls to fudgy brownies.
Other favorites include a simple sandwich bread, baked flour chips, and a flaky pie crust.
Manufacturers use the flour in bakery blends and snacks, covered in the article on commercial food manufacturing.
How It Compares With Other Flours
| Flour | Gluten | Swap behavior | Comparison |
|---|---|---|---|
| Wheat | Contains gluten | Closest texture match | Flour versus wheat |
| Almond | Gluten-free | Heavier, oilier, not a direct swap | Flour versus almond |
| Coconut | Gluten-free | Far more absorbent, needs extra eggs | Flour versus coconut |
| Chickpea | Gluten-free | Earthy taste, best in savory dishes | Flour versus chickpea |
| Arrowroot | Gluten-free | A starch, mainly for thickening | Flour versus arrowroot |
Ratios for every replacement are set out in the guide to flour substitutes that work.
Buying and Storing
Good flour is fine, white or creamy, dry to the touch, and free of sour or musty smells.
Brand differences are tested in Otto’s versus Bob’s Red Mill.
Store it airtight in a cool, dry place, because humidity causes clumping, mold, and off flavors.
Methods are explained in the guide to storing and preserving flour, with warning signs listed under how to spot spoiled flour.
Anyone planning to sell can start with the guide to a flour production business.
Conclusion
Cassava flour is the whole root, peeled, dried, milled, and sieved, which sets it apart from refined tapioca starch.
Quick, unfermented drying gives white high quality flour, while fermentation produces lafun for Nigerian swallow.
The flour is gluten-free and starchy, with little protein and a high glycemic response in several Nigerian studies.
Codex limits moisture to 13 percent and cyanide to 10 milligrams per kilogram, so careful processing matters.
Store it airtight in a cool place, and message Cassava Pathway on WhatsApp for triple-sieved flour or processing advice from Ntigha.
Frequently Asked Questions
Is it the same as tapioca flour?
No, it uses the whole peeled root, while tapioca flour is only extracted starch.
The whole-root product keeps more fiber and minerals, and it behaves differently in baking.
Can it replace wheat flour in recipes?
It can in many recipes, though it absorbs more liquid than wheat, so start with less.
Yeast breads usually need eggs or binders because there is no gluten.
Is it naturally gluten-free?
Yes, cassava contains no wheat, rye, or barley, so pure flour is naturally gluten-free.
Choose certified products if you have celiac disease, since shared mills can contaminate it.
How long does it keep?
Well-dried flour stored airtight lasts months, and one of my packs stayed good for a year.
Discard any flour that smells sour, musty, or shows clumps of mold.
