Cassava - pronounced [kuh-sah-vuh] & also known as Yuca Root - has been a staple food for millions around the world for centuries. We dry and grind this delicious and sustainable root vegetable into a clean-tasting flour you can count on again and again.

You may have heard of cassava flour's commonly known cousin, tapioca. While they both come from the same root, they function quite differently - both in baking and in your digestive system. It may help to think of tapioca like cornstarch, and cassava flour like corn flour. Though from the same source, they are not usually interchangeable.

Otto's Naturals - Cassava Flour is really easy to use! In most recipes, either sub it in 1:1 by weight - or if your recipe calls for cups, just reduce flour volume by 25%. For example, if your recipe calls for 1 cup of all-purpose flour, just use 3/4 cup of Otto's!

Please check our recipe section out to see the possibilities for yourself! It's a whole food you can feel good about, and we can't wait for you to try it!


Hi there! We're Sadie, John, and Otto (our little CEO in the middle).

Otto's Naturals all started when I was pregnant with Otto. I began to take my health practitioner's advice to stay off grains much more seriously, but I couldn't find an easy-to-use flour replacement that didn't TASTE grain-free.

Two years later, Otto's Naturals Cassava Flour was born!

We are proud to bring you this revolutionary, single-ingredient, whole-food flour made entirely from Non-GMO Yuca root. Hope you love it as much as our family does!
