Why is Soup Thickness Important?
Consistency in cooking is not just about appearance; it significantly impacts how we experience food. A soup that’s too thin might feel watery, lacking the richness we often expect, especially with bean soups. On the other hand, overly thick soups can feel more like stews, dense and pasty. Striking a balance is key.
Thicker soups often feel more filling and luxurious, while thinner soups might be better suited for appetizers or light meals. When it comes to bean soup, a thicker consistency generally enhances the heartiness of the dish, making it more comforting and satisfying. Whether you prefer your bean soup silky smooth or slightly chunky, understanding the different ways to thicken your soup will give you more control over the final dish.

What Makes Bean Soup Thicker Naturally?
If you’re looking for natural ways to thicken your bean soup without adding artificial ingredients or extra flavors, these methods are for you.
1. Mashing or Blending Beans
One of the simplest and most effective answers to the question “What makes bean soup thicker?” is mashing or blending a portion of the beans. Beans are naturally starchy, which makes them a great thickening agent without needing to add anything extra. By blending some of the cooked beans into a smooth puree and stirring them back into the soup, you’ll instantly thicken the dish.
How to Do It:
- Cook your beans thoroughly until they are soft and easy to mash.
- Remove a portion of the beans (about one cup) and place them in a bowl or blender.
- Mash the beans with a fork or blend them until they reach a smooth, creamy consistency.
- Stir the mashed or blended beans back into the soup and mix well.
This method works well with many types of bean soups, from black bean soup to navy bean soup, because it doesn’t alter the flavor. You’re essentially using the beans themselves to make the soup thicker, ensuring a consistent taste.
Benefits:
- Natural thickening: You’re using the ingredients already in the soup.
- No added flavor: This method keeps the flavor profile intact.
- Simple and quick: You don’t need to add any extra ingredients.
Additional Tips:
- If you prefer a chunkier texture, only mash part of the beans, leaving the rest whole.
- For a smoother, creamier soup, use an immersion blender to blend more of the beans directly in the pot.

2. Letting the Soup Simmer Longer
Another natural method to thicken bean soup is simply letting it simmer longer. As the soup cooks, water evaporates, and the liquid reduces, leading to a thicker consistency. This method is particularly effective if you don’t want to add any additional ingredients.
How to Do It:
- Once your soup has reached a boil, reduce the heat to a simmer.
- Leave the soup uncovered and allow it to cook for an additional 15-30 minutes.
- Stir occasionally to prevent the soup from sticking to the bottom of the pot.
As the soup simmers, the flavors will also intensify, making it even more delicious. This method is a good choice if you want to avoid changing the flavor or texture of the soup with thickeners like cornstarch or flour.
Benefits:
- No additional ingredients: You’re simply reducing the liquid by evaporation.
- Enhanced flavor: As the soup simmers, the flavors become more concentrated.
- Easy to do: Just let the soup cook longer – no extra steps needed.
Drawbacks:
- Time-consuming: This method can take longer than others.
- Requires attention: You’ll need to stir the soup occasionally to prevent burning.
Simmering is a great option when you have time and want a naturally thickened, flavorful soup. However, if you’re in a hurry, other methods may be more suitable.
Using Starches to Thicken Bean Soup
Starches are a quick and reliable way to thicken soup. Whether you use cornstarch, flour, or another type of starch, these ingredients help absorb liquid and create a creamier texture.
3. Cornstarch Slurry
Cornstarch is a popular thickening agent in many types of soups and sauces. A cornstarch slurry is made by mixing cornstarch with cold water, then adding it to the soup. As the soup cooks, the cornstarch absorbs the liquid and thickens the mixture.

How to Make a Cornstarch Slurry:
- Mix 1 tablespoon of cornstarch with 1 tablespoon of cold water.
- Stir the mixture until smooth and lump-free.
- Slowly pour the slurry into the simmering soup while stirring constantly.
- Allow the soup to cook for a few minutes until it thickens to your desired consistency.
Cornstarch is an effective thickener because it doesn’t alter the flavor of the soup. It’s a good option if you want to thicken the soup quickly without changing the taste.

Benefits:
- Quick results: Cornstarch thickens the soup in just a few minutes.
- No added flavor: Cornstarch doesn’t affect the taste of the soup.
- Easy to use: Making a slurry is simple and requires minimal effort.
Drawbacks:
- Texture change: If you use too much cornstarch, the soup can become gelatinous or overly thick.
- Must be added carefully: Adding cornstarch directly to the soup without mixing it with water first can cause lumps.

4. Flour Slurry
If you don’t have cornstarch on hand, flour is another great option for thickening your bean soup. Like cornstarch, flour can be mixed with cold water to create a slurry that’s added to the soup.
How to Make a Flour Slurry:
- Mix 2 tablespoons of flour with 2 tablespoons of cold water.
- Stir until smooth and lump-free.
- Slowly add the mixture to the soup while stirring continuously.
Flour takes a little longer to thicken than cornstarch, so be patient and allow the soup to simmer for a few minutes after adding the slurry. You may also need to add more flour slurry if the soup doesn’t thicken to your liking.
Benefits:
- Readily available: Most kitchens already have flour on hand.
- Mild flavor: Flour doesn’t change the flavor of the soup significantly.
- Effective thickener: Flour works well for thickening soups and stews.
Drawbacks:
- Raw flour taste: If you don’t cook the flour long enough, the soup may taste slightly raw or pasty.
- More effort: You may need to whisk the slurry longer to avoid lumps.
When using flour, it’s important to cook the soup long enough to eliminate the raw flour taste. This method is perfect for those who prefer a slightly thicker texture than what cornstarch provides.
5. Using a Roux for Richness
A roux is a mixture of flour and fat (usually butter) that’s cooked together to create a thick paste. It’s a classic French technique used to thicken soups, sauces, and gravies. The roux adds both thickness and a rich, buttery flavor to the soup.
How to Make a Roux:
- Melt 2 tablespoons of butter in a saucepan over medium heat.
- Stir in 2 tablespoons of flour and cook for 2-3 minutes, stirring constantly, until the mixture turns a light golden color.
- Slowly whisk the roux into the soup and continue to cook until the soup thickens.
The key to making a good roux is to cook it long enough to eliminate the raw flour taste but not so long that it burns. A light roux will add thickness without drastically altering the flavor of the soup, while a darker roux will impart a nutty, toasted flavor.
Benefits:
- Rich flavor: The butter in the roux adds depth and richness to the soup.
- Velvety texture: A roux creates a smooth, creamy texture in soups and stews.
- Time-honored technique: Roux is a classic method for thickening soups and sauces.
Drawbacks:
- More steps: Making a roux requires an extra step compared to simpler methods like slurries.
- Caloric: The addition of butter increases the calorie content of the soup.
A roux is ideal for those who want to add both thickness and richness to their bean soup.
Using Alternative Starches for Thickening
While cornstarch and flour are the most common thickeners, there are other starch-based options that can give your bean soup a unique texture and flavor. These alternatives can work just as well and may even offer additional nutritional benefits or flavors that complement certain types of bean soup.

6. Masa Harina or Cornmeal
A common question is what makes bean soup thicker, and one effective way is blending beans. Masa harina is a type of flour made from finely ground corn, often used in Mexican cuisine. If you’re making a southwestern-style bean soup, masa harina can be an excellent thickener that also adds a subtle corn flavor, enhancing the dish.
How to Use Masa Harina:
- Mix 1 tablespoon of masa harina with 1 tablespoon of water to create a smooth paste.
- Stir the paste into the soup and let it simmer for 5-10 minutes, stirring occasionally.
- As the masa harina absorbs liquid, it will thicken the soup while imparting a mild corn flavor.
Similarly, cornmeal can also be used as a thickener, though it may give the soup a slightly grainy texture. To avoid this, whisk the cornmeal in vigorously or cook it down for longer to fully break down the grains.
Benefits:
- Adds flavor: Masa harina and cornmeal not only thicken the soup but also add a pleasant corn flavor, making them ideal for southwestern or Mexican-style bean soups.
- Gluten-free: Both masa harina and cornmeal are naturally gluten-free, making them excellent options for those with gluten sensitivities.
- Nutritional value: Cornmeal and masa harina add fiber and essential nutrients, making your soup more filling.
Drawbacks:
- Texture: Cornmeal can create a slightly gritty texture if not cooked thoroughly, so it requires careful attention.
- Flavor change: While the corn flavor can complement many soups, it might not work well with every type of bean soup, especially those with more delicate flavor profiles.
For soups like black bean or pinto bean soups, masa harina or cornmeal can enhance the overall flavor and texture while naturally thickening the dish.
Incorporating Vegetables to Thicken Bean Soup
Vegetables not only add nutritional value to your soup but can also serve as excellent thickeners. Starchy vegetables, in particular, help create a thicker consistency when they break down during cooking.
7. Mashed Potatoes
Mashed potatoes are an excellent natural thickener for bean soup because they have a high starch content. If you’re already making a soup that includes potatoes, such as ham and bean soup, you can simply mash some of the cooked potatoes to thicken the broth.
How to Add Mashed Potatoes:
- Boil or steam a medium-sized potato until it’s tender.
- Mash the potato with a fork, adding a little soup broth if needed to create a smooth consistency.
- Stir the mashed potato back into the soup, mixing well until it’s fully incorporated.
If you don’t have potatoes in your soup already, you can still use this method to thicken the soup without altering the overall flavor profile too much. It’s a versatile option that works well with most types of bean soup, including navy bean, kidney bean, and black bean varieties.
Benefits:
- Natural and mild: Potatoes add thickness without overpowering the flavor of the soup.
- Readily available: Most people have potatoes in their pantry, making this an easy, go-to solution.
- Hearty texture: Mashed potatoes create a thicker, more satisfying texture, perfect for hearty winter soups.
Drawbacks:
- Caloric increase: Potatoes are relatively high in carbohydrates, so they will add calories to your soup.
- Potential for over-thickening: If you add too many mashed potatoes, your soup could become overly thick and more like a stew.
8. Adding Other Vegetables
In addition to potatoes, other starchy vegetables like carrots, squash, and parsnips can also be used to thicken bean soup. These vegetables break down during cooking, releasing starches into the broth and naturally thickening the soup. Additionally, they add flavor and nutrients to the dish.
How to Use Vegetables to Thicken Soup:
- Chop the vegetables into small, even pieces to help them cook down faster.
- Add them to the soup at the same time as the beans or earlier, depending on their cooking time.
- Allow the vegetables to simmer until they’re soft enough to mash or break down naturally.
- For a smoother consistency, you can blend a portion of the vegetables along with the beans to thicken the soup even more.
Vegetables are a fantastic way to thicken soup while also boosting its nutritional content. They work particularly well in vegetable-based bean soups, where the additional flavors enhance the overall dish.
Benefits:
- Nutritional boost: Vegetables add essential vitamins and minerals to the soup.
- Natural thickener: Starchy vegetables break down naturally, thickening the soup without the need for added thickeners.
- Flavor enhancer: Vegetables like carrots and squash add subtle sweetness, which can complement the savory flavors of bean soup.
Drawbacks:
- Longer cooking time: Vegetables need time to break down and thicken the soup, so this method isn’t as fast as using cornstarch or flour.
- Texture change: Depending on the vegetables used, they may alter the texture of the soup in ways you might not want (e.g., adding chunks or fibers).
Adding vegetables is a versatile way to thicken bean soup, especially if you want to boost the nutritional content without resorting to artificial or processed thickeners.
