Creamy Potato Soup with Bacon Vinaigrette Recipe on Food52 (2024)

FAQs

Why isn't my potato soup creamy? ›

Most creamy potato soup recipes call for a dairy product of some kind. If you plan to make a thicker version, try using thicker dairy from the outset. For example, if a recipe calls for whole milk, try adding heavy cream instead toward the end of the cooking process (set the burner no higher than medium heat).

Add Flour Or Cornstarch

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.

Cream cheese can be a delicious and tangy thickener for mashed potatoes so it stands to reason that it can also be used to add body to your favorite silky potato soup recipes — right? The answer is yes. It only works well if you do it carefully, though.

It is important that the potatoes not be too finely chopped before cooking. If they are, too much starch will be released into the broth and a gummy texture will result. An unpleasant consistency can also result from the pureeing of the cooked soup.

Method 1: Whisk in a slurry of cornstarch or flour

Add equal parts water or soup liquid to the flour or cornstarch and whisk until they're completely combined in a slurry. Once you've created the slurry, slowly whisk it into soup liquid and bring it back to a simmer.

With a simple soup like potato, I would stick to salt and pepper only. If you do use other spices, be careful because they will easily overwhelm the delicate flavor. Some ingredients I like to include in potato soup: Cooked, chopped bacon.

If you started the soup with broth, stock or water, I would wait until the end to add the cream. You can warm the cream, or “temper” it, which is what I do. Take about half a cup of the hot broth and slowly add your cream to that, stirring constantly.

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.

Opt for Cornstarch or Arrowroot

In a small bowl, mix cornstarch or arrowroot with a small amount of cold water to form a slurry. Once the slurry is smooth, gradually pour it into the simmering potato soup. Stir well to ensure the slurry is evenly distributed.

Sour cream is an easy replacement for heavy cream. It can be easily stirred into a dish and offers another flavor profile to soups, stews and sauces. Plus, using it as a heavy cream substitute is a great way to use up that lingering tub in the fridge.

Can I use sour cream instead of cream cheese in soup? ›

With its thick texture and tangy, slightly sour flavor, it's great in dips and sauces, stirred into mashed potatoes or blended into a rich topping for a salad. It's not recommended for soups because the heat will cause the cream to curdle. Use 1 cup sour cream for 1 cup cream cheese to achieve desired results.

Yogurt, Sour Cream, and Crème Fraîche – Dairy like yogurt, sour cream, and crème fraîche can add a creamy acidity to soups, but can curdle and be unpleasant if cooked over heat for too long, so swirl these in last.

Timing is also crucial in potato-leek soup. Undercook the soup and the flavors won't meld; overcook it and you'll have a mixture of broken-down bits with little flavor or bite.

Another option for thickening soup is by using dairy like sour cream or yogurt. Start with a small dollop and stir before checking the consistency and adding more. We recommend using plain yogurt so you don't alter the taste of the soup. You can also use cream if you prefer.

It's possible that the variety of potatoes you used may have a firmer texture, even when fully cooked. For soups, it's generally recommended to use russet or Yukon Gold potatoes, as they tend to break down and become softer when cooked.

Opt for Cornstarch or Arrowroot

In a small bowl, mix cornstarch or arrowroot with a small amount of cold water to form a slurry. Once the slurry is smooth, gradually pour it into the simmering potato soup. Stir well to ensure the slurry is evenly distributed.

Cornstarch. Cornstarch is a very effective thickener, and a little bit can go a long way. Add cornstarch to a small amount of cold water or other liquid (wine or stock) and whisk into a thick slurry. Then the slurry can be stirred into a simmering soup, a bit at a time to set the final consistency.

The reason why your soup might be turning gluey or even slimy is that you're overworking your spuds. Potatoes are full of starches, which are complex carbohydrates that easily absorb liquid and turn soft — and eventually goopy — when submerged under hot water.
