How To Thicken Split Pea Soup


Split pea soup is a comforting and hearty dish that many people enjoy, especially during colder months. However, if you find that your split pea soup is too thin and watery, you may be wondering how to thicken it up to achieve a richer and more luxurious texture. In this blog post, we will explore various methods and tips to help you thicken your split pea soup to perfection.

1. Simmer for Longer

One of the simplest ways to thicken split pea soup is to simmer it for a longer period of time. This allows the peas to break down further and release more starch, which will naturally thicken the soup. Keep an eye on the consistency while simmering, and continue cooking until your desired thickness is achieved.

2. Puree a Portion

If you prefer a smoother texture, consider pureeing a portion of the soup. Use an immersion blender or a countertop blender to blend about half of the soup until smooth, and then mix it back into the remaining soup. This will not only help thicken the soup but also create a creamy and velvety consistency.

3. Add Mashed Potatoes

Adding mashed potatoes is a secret weapon when it comes to thickening split pea soup. The starch in the potatoes will bind with the liquid and create a thicker consistency. Cook a few peeled potatoes until they are tender, mash them well, and then stir them into the soup. Make sure to adjust the seasoning accordingly.

4. Use a Roux

A roux is a mixture of fat and flour that is commonly used as a thickening agent in soups and sauces. In a separate pan, melt some butter or heat oil over medium heat, then gradually whisk in an equal amount of flour until it forms a smooth paste. Cook the roux for a couple of minutes to remove the raw flour taste, and then gradually whisk it into the soup. Allow the soup to simmer for a few minutes, stirring continuously, until it thickens.

5. Incorporate Cornstarch or Arrowroot Powder

Cornstarch and arrowroot powder are often used as thickening agents in cooking. To thicken split pea soup using either of these, mix 1-2 tablespoons of cornstarch or arrowroot powder with an equal amount of cold water to create a slurry. Slowly pour the slurry into the simmering soup while stirring continuously. Continue to simmer the soup for a few minutes until it reaches the desired thickness.

6. Embrace the Power of Beans

If you have extra cooked beans on hand, such as white beans or chickpeas, adding them to your split pea soup can enhance both the flavor and thickness. Simply mash some of the beans and stir them into the soup, allowing them to break down and naturally thicken the soup. This is a great way to add some additional protein and fiber to your dish as well.


Thickening split pea soup doesn’t have to be a challenging task. Whether you choose to simmer it for longer, puree a portion, add mashed potatoes, use a roux, incorporate cornstarch or arrowroot powder, or embrace the power of beans, these methods will help you achieve a deliciously thickened split pea soup. Feel free to experiment with these techniques and adjust them to suit your personal preferences. So, next time you find yourself with a thin bowl of split pea soup, you’ll know exactly how to transform it into a thick and satisfying meal.

What are some common reasons why split pea soup may be too thin?
Split pea soup can be too thin due to various reasons. One common reason is using too much water or broth while cooking. Additionally, if the split peas are not cooked long enough, they may not release enough starch to thicken the soup. Another possibility is not adding enough vegetables or other thickening ingredients during the cooking process.
How can I thicken split pea soup without altering the flavor?
If you prefer not to alter the flavor of your split pea soup, you can try adding a small amount of cornstarch mixed with water. Gradually whisk in the cornstarch mixture while the soup is simmering until your desired thickness is achieved. Be sure to cook the soup for a few more minutes after adding the cornstarch to remove any raw flavor.
What other ingredients can I use to thicken split pea soup?
There are several options to thicken split pea soup. One popular choice is to add mashed potatoes. Simply boil and mash some potatoes separately, then stir them into the soup until well combined. Another alternative is to mix in some cooked rice or barley to help thicken the soup.
Can I use dairy products to thicken split pea soup?
While dairy products like heavy cream or milk can add richness and creaminess to split pea soup, they are not typically used solely for thickening purposes. If you choose to incorporate them, do so sparingly to avoid overwhelming the soup with a dairy flavor.
Are there any gluten-free options for thickening split pea soup?
Yes, there are gluten-free options available for thickening split pea soup. Cornstarch is a great gluten-free alternative, as well as arrowroot powder. Both can be used in the same manner as described earlier, by mixing them with water before adding them to the soup.
Can I use a blender or immersion blender to thicken split pea soup?
Yes, using a blender or immersion blender can help thicken split pea soup. Take a portion of the soup and blend it until smooth, then reintroduce it into the pot. This will help create a thicker consistency by breaking down some of the split peas and vegetables.
Is it possible to thicken split pea soup by letting it simmer longer?
Yes, simmering the soup longer can naturally thicken it as the split peas continue to cook and release starch. Be sure to check the seasoning and add any additional ingredients, such as vegetables or spices, before allowing it to simmer for an extended period.
