Mashed potatoes are a beloved side dish that can elevate any meal, but achieving the perfect consistency can be a challenge. If you’re struggling with runny or too-thin mashed potatoes, you’re not alone. In this article, we’ll explore the best ways to thicken mashed potatoes, from simple tweaks to more advanced techniques.
Understanding the Science of Mashed Potatoes
Before we dive into the solutions, it’s essential to understand the science behind mashed potatoes. The consistency of mashed potatoes depends on several factors, including:
- Starch content: Potatoes are high in starch, which can make them thick and gluey when cooked. However, overcooking or using the wrong type of potatoes can lead to a sticky, unappetizing texture.
- Moisture content: Potatoes contain a significant amount of moisture, which can make them prone to becoming too thin or runny when mashed.
- Emulsification: Mashed potatoes are an emulsion of starch, fat, and water. When these components are balanced, the potatoes will have a smooth, creamy texture. However, when the balance is disrupted, the potatoes can become too thin or too thick.
Simple Tweaks to Thicken Mashed Potatoes
If you’re looking for a quick fix to thicken your mashed potatoes, try these simple tweaks:
1. Add More Potatoes
One of the easiest ways to thicken mashed potatoes is to add more potatoes. This will increase the starch content and help absorb excess moisture. Simply boil or steam additional potatoes until they’re tender, then mash them with the existing potatoes.
2. Use Less Liquid
When mashing potatoes, it’s easy to add too much liquid, which can make them too thin. Try reducing the amount of milk, cream, or butter you add to the potatoes. You can always add more liquid later if needed, but it’s harder to remove excess liquid from the potatoes.
3. Add a Slurry
A slurry is a mixture of flour or cornstarch with a small amount of liquid. Adding a slurry to the potatoes can help thicken them quickly. Mix 1 tablespoon of flour or cornstarch with 2 tablespoons of cold water or milk until smooth, then add it to the potatoes.
Advanced Techniques to Thicken Mashed Potatoes
If you’re looking for more advanced techniques to thicken mashed potatoes, try these methods:
1. Use a Roux
A roux is a mixture of flour and fat that’s cooked until it’s lightly browned. Adding a roux to the potatoes can help thicken them and add flavor. Mix 1 tablespoon of flour with 1 tablespoon of butter or oil until smooth, then cook over low heat until lightly browned. Add the roux to the potatoes and mash until combined.
2. Add Grated Cheese
Grated cheese can help thicken mashed potatoes and add flavor. Try adding 1/4 cup of grated cheddar, Parmesan, or mozzarella cheese to the potatoes. The cheese will melt and help bind the potatoes together.
3. Use Greek Yogurt or Sour Cream
Greek yogurt or sour cream can help thicken mashed potatoes and add a tangy flavor. Try adding 1/4 cup of Greek yogurt or sour cream to the potatoes. The acidity in the yogurt or sour cream will help break down the starches and create a thicker consistency.
Other Ingredients to Thicken Mashed Potatoes
In addition to the techniques mentioned above, there are several other ingredients you can use to thicken mashed potatoes:
- Egg yolks: Egg yolks can help thicken mashed potatoes and add richness. Try adding 1-2 egg yolks to the potatoes and mash until combined.
- Breadcrumbs: Breadcrumbs can help absorb excess moisture and thicken mashed potatoes. Try adding 1-2 tablespoons of breadcrumbs to the potatoes and mash until combined.
- Pureed vegetables: Pureed vegetables like carrots, zucchini, or spinach can help thicken mashed potatoes and add flavor. Try adding 1/4 cup of pureed vegetables to the potatoes and mash until combined.
Common Mistakes to Avoid
When trying to thicken mashed potatoes, it’s easy to make mistakes that can lead to an unappetizing texture. Here are some common mistakes to avoid:
- Overmixing: Overmixing can make mashed potatoes gluey and unappetizing. Try to mix the potatoes just until they’re combined, then stop mixing.
- Adding too much liquid: Adding too much liquid can make mashed potatoes too thin. Try to add liquid gradually, stirring constantly, until the potatoes reach the desired consistency.
- Using the wrong type of potatoes: Using the wrong type of potatoes can lead to a sticky or gluey texture. Try using high-starch potatoes like Russet or Idaho for the best results.

What are the common mistakes that can lead to runny mashed potatoes?
One of the most common mistakes that can lead to runny mashed potatoes is over-mixing. When you over-mix the potatoes, you break down the starches, releasing excess moisture and resulting in a gluey, unappetizing consistency. Another mistake is adding too much liquid, such as milk or butter, which can make the potatoes too wet and difficult to thicken.
To avoid these mistakes, it’s essential to mix the potatoes just until they’re combined with the other ingredients, and then stop mixing. You can also try adding a little liquid at a time, checking the consistency as you go, to ensure you don’t add too much. Additionally, using high-starch potatoes, like Russet or Idaho, can help you achieve a fluffier, more stable mash.
How can I thicken mashed potatoes using starches?
There are several starches you can use to thicken mashed potatoes, including cornstarch, flour, and tapioca starch. To use these starches, mix a small amount with a cold liquid, such as milk or water, until smooth, and then add the mixture to the potatoes. This helps to prevent lumps from forming and ensures the starch is evenly distributed.
When using starches to thicken mashed potatoes, it’s essential to cook the potatoes for a few minutes after adding the starch mixture. This allows the starch to gelatinize and thicken the potatoes. You can also try adding a little grated cheese, like Parmesan or cheddar, which contains casein, a natural thickening agent that can help to stabilize the potatoes.
What is the role of fat in thickening mashed potatoes?
Fat plays a crucial role in thickening mashed potatoes, as it helps to coat the starches and prevent them from becoming too sticky or gluey. Adding a small amount of fat, such as butter or cream, can help to enrich the flavor and texture of the potatoes, making them more tender and creamy.
When using fat to thicken mashed potatoes, it’s essential to add it gradually, checking the consistency as you go.
