Pureeing veggies as a thick soup base is an option, but you can leave the pieces whole. The veggies release just the right amount of starch during cooking to thicken the soup.

Easy-to-access alternatives are wheat flour, arrowroot flour, and rice flour. These are good alternatives to cornstarch because they are more nutritious and contain fewer carbohydrates and calories. Xanthan and guar gum are much stronger thickeners than cornstarch, but they can be harder to obtain and use.

Because cornstarch is pure starch, it has twice the thickening power of flour, which is only part starch. Thus, twice as much flour is needed to achieve the same thickening as cornstarch. To thicken sauces, cornstarch is combined with cold water first, which is called a slurry.

Glucomannan

It's a far more powerful thickening agent by amount, so use about half the amount of glucomannan as you would cornstarch. About one teaspoon to every cup of liquid is a common suggestion. Since glucomannan tends to clump in high heat, mix it with cold water before adding it to your dish.

Foods like rice, bread, potatoes and beans are naturally high in starches, which, when broken down, act as a thickening agent. With rice, the grains will break down into the soup as it's simmered and stirred, releasing the starches and thickening the soup.
