Easy Ways to Make a Soup Thicker

There are different techniques for thickening soups to make them creamy. Dairy products, immersion blenders, and starches or flours are just a few. Let’s take a look at these methods!

Thicken with a Starch

Cornstarch is an easy way to thicken soup—just whisk 1 tablespoon with 4 tablespoons warm milk or water to make a slurry. Stir it in, boil for at least a minute to thicken, but avoid overcooking or the soup may thin out again.

All-purpose flour can thicken soup like cornstarch, but with more versatility. Use a 2:1 flour-to-liquid ratio to make a slurry, or cook flour with fat to make a roux. For best results, mix the roux into a small portion of soup first, then stir it back into the pot.

Xanthan gum is a sugar-based thickener that can slightly sweeten soup. To avoid clumps, whisk in just a teaspoon at a time over low heat.

Thicken with Dairy

Heavy Cream: Heavy cream (or other high-fat dairy like coconut milk or sour cream) adds rich, velvety texture to soups. Stir it in slowly over low heat near the end of cooking to avoid curdling.

Yogurt or Buttermilk. To prevent any curdling at all, yogurt and buttermilk can be added to cold soup if you’re eating leftover soup. If you’re eating the soup the same day, add these thickening agents slowly to a pot of soup on low heat.

Thicken with a Blender

You can thicken soup without adding anything by using an immersion blender right in the pot. Blend vegetables or potatoes for a thicker texture, or blend only part of the soup for a chunkier finish. This method changes texture more than flavor, often resulting in a slightly mushier consistency.

For a smoother texture, use a food processor or blender. Let the soup cool slightly, start on low, then increase speed. Always cover the top with a towel to prevent hot liquid from splattering.

Thicken with an Egg

Surprisingly, egg whites and egg yolks are great thickeners too! This option is good for lemony, creamy soups. You’ll temper your eggs by whisking them together with a small amount of soup in a small bowl.

Then slowly add this mixture into your pot of soup. This one’s not as common, so if you’re all out of options, give this a try!

Thicken with Add-Ins

Starchy ingredients like rice, potatoes, pasta, beans, or bread release starch as they cook, naturally thickening your soup. Add them early so they have time to break down and add body.

FAQs

Is it better to thicken soup with flour or cornstarch?

Cornstarch may be a better thickener over flour. It’s important to know that cornstarch is twice as powerful as flour. Flour also begins to form clumps sooner and faster if you aren’t mixing quickly enough. On the other hand, cornstarch shows an immediate change in your soup.

Does soup thicken best covered or uncovered?

Cooking any kind of soup uncovered allows water to evaporate. If your goal is to thicken a soup, don’t use the lid. The longer you cook your soup uncovered, the less liquid it will contain and the thicker your soup will be.

How can I thicken soup without it changing the taste?

You can either blend starches or vegetables in your soup, or use more starches—like beans, pasta, and rice—during the cooking process.

Can you thicken soup by reducing it?

Yes, by leaving your soup uncovered as it cooks, you can reduce the amount of liquid it contains.

What is the best thickening agent for soup?

Cornstarch. A little bit goes a long way if done properly.

How can I thicken soup naturally?

Using natural starches like potatoes, rice, or beans in your soup will naturally release their own starch in the soup as it’s cooking.

How long does it take for soup to thicken up?

Normally it takes from 3 to 5 minutes.

What is the strongest thickener?

Some say that potato starch is the strongest because it is a coarser starch that easily soaks up liquid.

How do you know when thickening is complete?

Judge this by the taste and consistency. There shouldn’t be any raw flour or starchy taste when it’s completed. It should also have a smooth texture that can coat the back of a spoon.
