How to thicken soup? ›

Add flour or cornflour

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.

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 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.

Add extra water as it cooks if the soup seems too thick. 5) Add ingredients that don't need much cooking time such as canned beans, diced cooked meats, shellfish, pasta or cooked rice; about a cup of such addition usually suffices.

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 flour or cornflour

You can also use flour or cornflour to thicken a soup. Put a tablespoon of either into a small bowl and stir in 2-3 tbsp of the soup until you have a smooth mixture. Stir this back into the soup and bring it to a simmer.

Remember that some soups will thicken on their own as they sit and cool; the ingredients may continue to absorb liquid, so yours might just need another day to reach perfect consistency.

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. slurry to 4 cups of soup.

Does soup thicken covered or uncovered? ›

Cooking a soup, stew, or sauce uncovered allows water to evaporate, so if your goal is to reduce a sauce or thicken a soup, skip the lid. The longer you cook your dish, the more water that will evaporate and the thicker the liquid becomes—that means the flavors become more concentrated, too.

Chunkier soups, like black bean or lentil, tend to lean thick—and, it must be said, gloopy. To thin them out (and dial down the intense salinity), add more water or low-sodium stock while they're heating. (If you overdo it, don't stress: Continue simmering until the liquid has reduced to your desired consistency.)

Let the Broth Evaporate and Cook Longer

If your broth tastes thin and bland, you may want to cook and let it evaporate for longer. That helps concentrate its flavors and gives you a better-tasting soup broth. Be sure to remove the lid to let the steam escape.

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.

You don't need to use commercial thickeners for foods, since soup and other foods can be easily thickened with powdered potatoes (used for instant mashed potatoes), rice cereal, tapioca, or Jell-O, for example.

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.

Whether you use exact measurements or simply top sautéed veggies, aromatics, or legumes with liquid before boiling them, you might end up with more cooking liquid than you bargained for. When there's a disproportionately high ratio of liquid to solids, blending everything all at once will result in watery soup.

In a separate bowl, dissolve a teaspoon or two of cornstarch or all-purpose flour in a small amount of cold water. Add the slurry to the bubbling soup. The soup should thicken up. Add more cornstarch or flour as needed until the soup reaches your desired consistency.
