Add a starchy vegetable like squash, pumpkin, sweet potato or white potato to your soup and let it simmer.

Add Flour Or Cornstarch

Instead, ladle a small amount of broth into a separate bowl and let it cool. Add a few tablespoons of flour or cornstarch to the bowl and whisk until it's blended smooth. Next, bring the soup to a simmer and add the mixture back to the pot. Pro tip: Don't dump in the entire mixture at once.

The most classic and surefire way to thicken a broth-based soup is with a cornstarch slurry. Whisk together equal parts cornstarch (or arrowroot) and water or broth, then whisk it into the pot of soup. A good ratio to get to a pleasant thickness without your soup tasting goopy or heavy is one tablespoon.

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.

Soup Thickening Method: Cornstarch Slurry

I made a classic slurry by whisking cornstarch and hot broth until smooth in a small bowl. I drizzled it into the soup gradually, and brought it to a boil to fully activate, thicken, and cook out the starch flavor before adding more.

Add more liquid: The simplest solution is to add more liquid, such as water, broth, or milk. Start by adding a small amount and gradually add more until you reach the desired consistency. Use a blender: If you have a blender, you can puree the soup in batches, adding more liquid as needed.

Use a butter and flour paste

You can also use a flour and butter paste called a beurre manié to thicken a soup. Just mix 2 tsp flour with 2 tsp soft butter, and while the soup is simmering, stir the paste into the pan. The butter will help disperse the flour throughout the liquid.

Add Flour, Cornstarch, or Other Thickener: Starches thicken soup and give it body. Whisk a few tablespoons of starch into a little of the broth in a separate bowl before whisking it into the main pot. This prevents the starch from clumping and helps it dissolve into the soup evenly.

Cornstarch is a great option as it is a natural thickening agent, but you'll want to be careful about how much you use. Start with 1 tablespoon of cornstarch whisked together with cold water to create a slurry. Then, gradually add the slurry to the soup, letting it boil for one to two minutes before adding more.

Is cornstarch or flour better for thickening soup? ›

It's important to note that cornstarch has twice the thickening power of flour. If you need to substitute cornstarch to thicken liquid in a recipe that calls for ¼ cup (four tablespoons) flour, you only need two tablespoons cornstarch.

Add Eggs

To use egg yolks to thicken a soup, whisk the yolks on their own in a mixing bowl and slowly ladle in hot soup bit by bit, whisking constantly, until the mixture is hot to the touch.

Heavy cream

Use heavy cream as a keto-friendly thickening option for your soups and broths. Heavy cream has more fat than regular whole milk, so you can add it to your soup recipes without worrying about it curdling.
