FAQs

How do you make potato soup not grainy? ›

When the soup comes to a boil, reduce heat a touch to maintain a gentle boil. Boiling at too high of a temperature will break down your potatoes and make your soup grainy. You want your potatoes to be fork-tender but still have a little “bite” to them.

How do you make soup smooth? For a soup with a smooth consistency, work with veggies that are soft but not mushy. Additionally, streaming oil or cream into the soup can better emulsify the ingredients for a silkier texture. Blender features can also play a major role in getting your soup to the right consistency.

One trick to make your potato soup a little less grainy is to add some form of dairy –- cream, milk, or even cheese. Because dairy is generally creamy in texture, that characteristic will carry over into your soup.

This starch will bond with the broth, causing the body of the soup to become slimy. To guard against this, it is best to mash the potatoes into the soup with a potato masher or a large fork, or to run the soup solids through a food mill to crush them.

Russet potatoes, as a member of the starchy/floury potato family, are inherently grainy. Using them in soup will result in an unpleasant gritty texture. When making potato soup, be sure to reach for a waxy variety such as fingerling potatoes, red potatoes, or baby potatoesto get a smoother texture.

Your soup may become grainy if the cheese or dairy curdles. With a recipe like the one that follow you shouldn't have trouble because the cheese is added as a finishing component, off heat. But to avoid “breaking” the dairy while reheating (or with other dairy-rich soups), take it low and slow.

The best options for thickening soup are cream or half and half. Plain yogurt or even freshly grated cheese works well and adds an extra layer of tangy, salty flavor. Add the dairy at the end and avoid bringing the soup to a boil since this can cause yogurt, cheese, or cream to split.

To achieve a silky-smooth texture, keep the blender running for at least 1 to 2 minutes in order to fully break down the solids. A common mistake is to not run the blender long enough. This results in a grainy-textured soup. The soup should be blended long enough to create a silky-smooth texture.

Starchy Vegetables

Grate a starchy vegetable like squash, pumpkin, sweet potato, or white potato into the soup and let it simmer. It will release that starch and help to thicken the liquid as it cooks.

What is the best thickening agent for potato soup? ›

Add Flour Or Cornstarch

You can thicken soup by adding flour, cornstarch, or another starchy substitute.

Not Adding Acid

If a soup is tasting bland in the bowl, consider adding acid rather than salt. A squeeze of lemon or lime, or a dash of yogurt or sour cream can add brightness to the bowl.

Potatoes are delicate in that they can be over mashed and over blended. This causes their starches to be released and turn into a gluey, gummy mess.

It's best to use fresh, firm potatoes. Acidic Ingredients: If your soup contained highly acidic ingredients (e.g., tomatoes), it could have affected the texture of the potatoes. Acidic ingredients can slow down the softening process of potatoes.

In order to fix lumpy or gritty mashed potatoes you may need to add more liquid to them such as melted butter and some milk.

One important thing to know about potatoes is that water is their enemy. Yep, it cooks the potatoes, but if they spend too long bathing, they'll become waterlogged. And no matter what type of potato you're boiling, waterlogged potatoes will be grainy, crumbly and mushy with little flavor (it'll leach into the water).

By far the easiest way to thicken soup that guarantees a non-grainy result is by adding in cornstarch slurry. The key is ensuring the slurry mix has the adequate proportions: two parts liquid (cold or room temperature) to one part cornstarch.
