Both come from starchy plant roots, but that is nearly where the similarity ends. I have milled cassava flour for years, and arrowroot behaves like an entirely different ingredient once it hits a hot pan.
Cassava flour and arrowroot both come from starchy tropical roots, but they are processed differently and perform very differently in the kitchen.
Cassava flour uses the whole cassava root, keeping fiber and a mild, nutty taste that mimics wheat flour reasonably well.
Arrowroot comes from the rhizomes of Maranta arundinacea, processed into a fine, nearly flavorless starch prized for smooth, clear thickening.
Their glycemic index differs meaningfully too, which matters if you are managing blood sugar and choosing between the two.
This guide compares both using USDA nutrition data, so you can pick the right one for your recipe.

Cassava Flour Overview
Cassava flour comes from peeling, drying, and grinding the whole root into a fine powder, keeping fiber and micronutrients that pure starch products lose.
It works as a near 1:1 wheat substitute in bread, pancakes, and pastries, adding real structure and chewiness.
The cassava flour guide covers its production and full nutrition profile in more depth.
Cassava also carries naturally occurring cyanogenic compounds that proper processing removes, covered fully in our post on cassava flour and cyanide safety.
What Is Arrowroot
Arrowroot is a starch extracted from the rhizomes of Maranta arundinacea, a tropical plant native to South America and the Caribbean, unrelated to cassava.
The rhizomes are washed, grated, and processed into a fine white powder.
It is valued for its neutral taste and its ability to create a smooth, clear consistency in sauces and gravies.
Unlike cassava flour, arrowroot contains no gluten and produces a light, crisp texture when used in baking rather than a dense, chewy one.
Nutrition Side by Side
Cassava flour and arrowroot differ sharply, despite both being starchy, gluten-free root products.
| Nutrient (per 100g) | Cassava Flour | Arrowroot Flour |
|---|---|---|
| Calories | 360 kcal | 357 kcal |
| Carbohydrates | 87g | 88g |
| Protein | 1 to 2g | 0.3g |
| Fat | 0.5g | 0.1g |
| Fiber | 3g | 3.4g |
Cassava flour figures come from USDA-sourced nutrition data, and arrowroot figures come from the USDA FoodData Central entry for arrowroot flour.
Arrowroot actually carries a moderate amount of fiber, contrary to the common assumption that it has none, though it remains lower in protein than cassava flour.
Both flours help close the fiber gap most adults face, since average intake runs near 16 grams against a 25-38 gram target, per USDA data.
On glycemic index, most comparative sources report arrowroot testing meaningfully lower than cassava-based products.
Reported values vary widely by preparation method and study, based on glycemic index data compiled by FoodStruct.
This is worth knowing specifically if you are managing blood sugar and choosing between the two.

Texture and Baking Performance
Cassava flour absorbs moisture well, giving baked goods a denser, chewier structure suited to bread, muffins, and pancakes.
Arrowroot creates the opposite effect, keeping pastries and cookies light and delicate rather than adding density.
As a thickener, arrowroot produces a clear, glossy finish in sauces, soups, and pie fillings, outperforming cassava flour for that specific job.
Combining both in a gluten-free blend gives you cassava flour’s structure alongside arrowroot’s lightness and thickening power, a common approach in commercial gluten-free flour mixes.
Which One Should You Choose
Choose cassava flour if you need a wheat-like texture with real structure for bread, tortillas, or muffins.
Choose arrowroot if you need a clear, glossy thickener or a light, delicate texture in cookies and pastries.

Conclusion
Cassava flour and arrowroot solve different problems in the kitchen, and your recipe should decide which one you reach for.
Choose cassava flour when you want structure and chewiness for bread, pancakes, or muffins that should behave like wheat.
Choose arrowroot when you need a clear, silky thickener or a lighter texture in delicate pastries and cookies.
I process cassava into flour regularly, but I still keep arrowroot on hand for the recipes that genuinely need it. Test a small batch before committing a full recipe to either one.
Frequently Asked Questions
Does arrowroot have a lower glycemic index than cassava flour?
Most sources report arrowroot testing meaningfully lower on the glycemic index than cassava-based flour, though exact values vary by study and preparation method.
Does arrowroot contain any fiber?
Arrowroot flour actually contains a moderate amount of fiber, around 3.4 grams per 100 grams, contrary to the common assumption that it has none.
Which flour is better for baking bread?
Cassava flour provides more structure for bread and muffins, while arrowroot creates lighter, more delicate results in cookies and pastries.
Is arrowroot a good thickener for sauces?
Yes, arrowroot creates a clear, glossy finish in sauces and pie fillings, making it a better choice than cassava flour for delicate thickening.
