How to Thicken Soup Quickly, No Cornstarch Required? ›

To thicken soup, try adding a dash of cream or a spoonful of yogurt. Or, you can add coconut milk for a vegan-friendly option. If you want to give the soup a creamy, savory flavor, try stirring in some beaten eggs to thicken it. You can also add starches, like chunks of bread, oats, or flour, to thicken a hardy soup.

First, you can create a slurry by whisking 2 tablespoons of flour with cold water and adding it gradually to the soup. Another method of using flour to thicken soup is by making a roux on the stovetop. A roux, which is a mixture of fat and flour, is often used as a base for sauces and is an easy way to add starch.

Flour Slurry

Combine equal parts of flour and cold water in a cup. Mix it until it's smooth and stir it into the sauce. Bring the sauce to a simmer for 5 minutes. A general rule is use 2 tsp (3 grams) of flour to thicken 1 L (34 fl oz) of liquid.

You can thicken soup by adding flour, cornstarch, or another starchy substitute. For the best results, never add flour or cornstarch directly to your soup. If you do, it will clump up on top. Instead, ladle a small amount of broth into a separate bowl and let it cool.

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.

What are the 4 ways to thicken a sauce or soup? ›

My secret weapon. Instant mashed potatoes. Pour them on, stir them in, give it a minute or 2, and it'll be nice and thick.

Occasionally, a soup recipe will call for beaten eggs as a thickening agent. Both whole eggs and yolks can be used. To avoid curdling the eggs, start by drizzling about ½ cup of the hot broth into the eggs, stirring vigorously while you pour. Then add the egg mixture to the soup and cook until thickened.

Arrowroot powder (a.k.a. arrowroot flour and arrowroot starch) delivers thickening results that are very similar to what cornstarch offers. Arrowroot makes a beautifully shiny sauce, and you can use the same amount of arrowroot that you would cornstarch.

Like most starches, cornstarch is most commonly used to thicken stews, sauces and even puddings. When used sparingly, cornstarch is practically flavorless and works alongside several different flavored foods.

Start by using 1 tablespoon of cornstarch at a time, mixed with 2 tablespoons of water. More cornstarch slurry can be added, but be sure not to add too much. Only mix in a small amount of slurry at a time to ensure that your soup will thicken properly. Using corn starch is a fast, effective way to thicken soup.

Cornstarch has twice the thickening power of flour. When a gravy, sauce, soup or stew recipe calls for flour, use half as much cornstarch to thicken. To thicken hot liquids, first mix cornstarch with a little cold water until smooth. Gradually stir into hot liquid until blended.

Even if you don't purée the soup with a blender, potatoes release starch as they cook — thickening the broth with a satisfying velvety consistency.
