Let’s dive into what thickens potato soup and how you can achieve a creamy, delicious texture every time.
The Role of Starch in Potato Soup
Understanding what thickens potato soup starts with knowing how starch works. Potatoes naturally contain starch, which thickens soups as they cook. The type of potato you choose matters. For instance, Russet potatoes are high in starch and are excellent for creating a thick, creamy soup. On the other hand, Yukon Gold potatoes release less starch and maintain their shape better, resulting in a smoother, thinner consistency.
When you cook potatoes, they release their starch into the soup, thickening it naturally. If you want to further thicken the soup, mashing or blending some of the cooked potatoes will help create a heartier texture without adding any extra ingredients.
Classic Thickening Agents: Flour and Cornstarch
Two of the most common ways to thicken potato soup are by using flour or cornstarch. These are pantry staples that can easily adjust the thickness of your soup.
Using Flour
Flour is a traditional thickener that works well in soups. To use flour effectively, create a slurry by mixing equal parts flour and cold water or broth until smooth. Slowly add the slurry to the soup while stirring constantly. This prevents lumps and allows the soup to thicken gradually. After adding the flour, let the soup simmer for at least 5-10 minutes to cook out the raw flour taste.
Using Cornstarch
Cornstarch is another reliable thickening agent. To use it, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water to create a slurry. Add the slurry to your soup, stirring constantly. Cornstarch thickens the soup more quickly than flour and is also gluten-free, making it a great option for those with dietary restrictions.

Dairy-Based Thickeners: Cream, Milk, and Cheese
If you’re wondering what thickens potato soup in a way that also adds richness, look no further than dairy products. Cream, milk, and cheese are excellent choices that add both flavor and thickness to your soup.
Heavy Cream or Half-and-Half
Adding heavy cream or half-and-half gives potato soup a rich, velvety texture. The fat in the cream helps thicken the soup while adding depth of flavor. Simply stir the cream in toward the end of cooking and let it simmer gently to thicken.
Milk
For a lighter option, use whole milk or evaporated milk. While milk won’t thicken the soup as much as cream, it still adds a creamy consistency. Slowly stir the milk into the soup and heat gently to avoid curdling.
Cheese
Cheese, such as cheddar or cream cheese, is another great thickening option. Shredded cheese should be added slowly and stirred continuously to ensure it melts evenly, thickening the soup while adding a rich, savory flavor.
If you enjoy cheesy dishes, you might want to try jalapeño scalloped potatoes, another recipe where cheese plays a key role in thickening.
Other Thickening Ingredients: Bread, Beans, and Grains
If you’re looking for more unique methods of what thickens potato soup, consider adding ingredients like bread, beans, or grains.
Bread Crumbs
Adding bread crumbs is a simple way to thicken potato soup. Bread absorbs liquid and breaks down, helping to thicken the soup while adding texture. This technique works well for rustic soups and gives the soup a heartier feel.
Beans
Blended or mashed beans are another healthy thickening option. White beans, such as cannellini or navy beans, have a neutral flavor and blend smoothly into the soup, adding both thickness and nutrition.
Grains
Rice, barley, or quinoa can also be used to thicken potato soup. As these grains cook, they release starches that thicken the soup naturally. Be sure to cook the grains thoroughly to ensure they release enough starch and soften completely.
Non-Traditional Thickening Techniques: Blending and Pureeing
One of the most effective methods of what thickens potato soup is using simple blending or pureeing techniques. This method doesn’t require any additional ingredients and can still result in a thick, creamy texture.
Blending Potatoes
Blending a portion of the potatoes in your soup is one of the easiest ways to thicken it. You can use an immersion blender or remove some of the soup to blend in a regular blender. Blending the potatoes adds body to the soup while keeping the flavors intact.
Pureeing Vegetables
In addition to potatoes, you can also puree other vegetables like carrots, celery, or onions to thicken the soup. This not only adds thickness but also enhances the flavor profile of the dish. Pureeing vegetables is a great option if you’re looking for a gluten-free or dairy-free thickening method.
Thickening Potato Soup Without Dairy or Gluten
For those following a dairy-free or gluten-free diet, there are still plenty of options for what thickens potato soup.
Potato Starch
Potato starch is an excellent gluten-free thickening option. It dissolves easily in liquid and thickens the soup without altering the flavor. To use potato starch, mix it with cold water to form a slurry, then stir it into the soup while it simmers.
Coconut Milk
If you want a dairy-free alternative, coconut milk is a fantastic choice. Full-fat coconut milk adds a rich, creamy texture and a subtle sweetness that complements the potatoes well.
Nutritional Yeast
Nutritional yeast is another great dairy-free option for thickening soup. It also adds a cheesy flavor without the use of actual cheese, making it a popular choice for vegan soups.

Common Mistakes When Thickening Potato Soup
Even with the right ingredients, mistakes can happen. Here are some common pitfalls to avoid when learning what thickens potato soup:
- Adding Too Much Thickener: Over-thickening your soup can result in a gummy texture. Add thickening agents gradually and stir constantly to monitor the consistency.
- Not Mixing Slurries Properly: If your flour or cornstarch slurry isn’t mixed properly, you’ll end up with lumps. Always whisk the slurry until smooth before adding it to the soup.
- Overcooking the Soup: Overcooked potatoes can break down too much, making the soup overly starchy and losing the desired texture. Pay attention to cooking times.
