How to Thicken Mashed Potatoes That Are Too Watery?
If your mashed potatoes are more soup than side dish, don’t despair! The quickest and easiest solutions involve adding more cooked potatoes or dehydrated potato flakes, while other effective methods include incorporating dairy products, like warm milk, cream, or cream cheese, and carefully evaporating excess liquid.
The Soggy Potato Predicament: A Common Culinary Conundrum
Mashed potatoes, a comforting staple on dinner tables worldwide, are surprisingly delicate. Achieving that perfect creamy consistency can be trickier than it seems. Too much liquid during the cooking or mashing process, or even inherently watery potatoes, can lead to a less-than-desirable, soupy result. But fear not! With a few simple techniques and a little kitchen savvy, you can easily rescue your watery mashed potatoes and transform them into the fluffy, flavorful side dish you envisioned.
Understanding Why Potatoes Get Watery
Before diving into the fixes, it’s helpful to understand the common culprits behind watery mashed potatoes:
- Potato Variety: Certain potato varieties, like red potatoes, tend to retain more water than others. Russet and Yukon Gold potatoes are generally preferred for their drier texture and ability to absorb flavors.
- Overboiling: Boiling the potatoes for too long allows them to absorb excess water, leading to a mushy and watery consistency.
- Insufficient Draining: Failing to thoroughly drain the cooked potatoes before mashing is a major contributor to watery mashed potatoes.
- Too Much Liquid: Adding too much milk, cream, or butter during the mashing process can easily tip the balance and create a watery mess.
Rescue Missions: Effective Thickening Techniques
Now, let’s explore the arsenal of techniques you can use to thicken those watery mashed potatoes:
- Add More Potatoes: This is perhaps the most straightforward solution. Boil and mash more potatoes (preferably the same variety) and incorporate them into the watery batch.
- Potato Flakes (Dehydrated Potatoes): Instant potato flakes are a kitchen staple for a reason! They readily absorb excess liquid and can quickly thicken your mashed potatoes. Start with a small amount and gradually add more until you reach the desired consistency.
- Warm Dairy Products: Adding warm milk, cream, or half-and-half can help thicken the potatoes and add richness. Warming the dairy beforehand prevents the potatoes from cooling down and becoming gummy.
- Cream Cheese or Sour Cream: These ingredients not only add thickness but also a delightful tanginess to your mashed potatoes. Start with a tablespoon or two and adjust to taste.
- Evaporation: Gently heating the mashed potatoes in a pot over low heat can help evaporate excess liquid. Stir frequently to prevent scorching. Be careful not to overcook them, as this can make them gummy.
- Roux: While less traditional, a roux (a mixture of butter and flour cooked together) can be used to thicken mashed potatoes. Add it gradually and stir well to avoid lumps.
Preventing Watery Potatoes: Proactive Strategies
Prevention is always better than cure. Here are some tips to avoid watery mashed potatoes in the first place:
- Choose the Right Potatoes: Opt for Russet or Yukon Gold potatoes, known for their drier texture.
- Don’t Overboil: Cook the potatoes until they are fork-tender, but not mushy.
- Drain Thoroughly: Drain the cooked potatoes in a colander and allow them to steam dry for a few minutes before mashing.
- Warm Liquids: Warm the milk, cream, or butter before adding it to the potatoes.
- Add Liquids Gradually: Add liquids slowly, a little at a time, until you reach the desired consistency.
- Dry Heat: After mashing, you can spread the mashed potatoes in a baking dish and bake at a low temperature (300°F) for a short period to dry them out slightly.

Frequently Asked Questions (FAQs)
Can I use cornstarch to thicken mashed potatoes?
While technically possible, using cornstarch is not recommended for thickening mashed potatoes. Cornstarch can give the potatoes a slightly slimy texture. Stick to the methods outlined above for a better result.
What if I don’t have any more potatoes or potato flakes?
If you’re truly out of potatoes and flakes, try using a small amount of instant mashed potato powder. This will have a similar effect to the flakes. As a last resort, you could consider a very small amount of flour or a roux, but be careful not to overdo it.
How much milk or cream should I add to thicken watery mashed potatoes?
Start with a small amount, about 1/4 cup at a time, and gradually add more until you reach the desired consistency. Warming the dairy first is crucial.
Can I use cold milk or cream to thicken mashed potatoes?
It’s highly recommended to use warm milk or cream. Cold dairy can lower the temperature of the potatoes and make them gummy.
My mashed potatoes are lumpy and watery. Can I fix them?
Yes, you can try to fix lumpy and watery mashed potatoes. First, use an immersion blender or a potato ricer to smooth out the lumps. Then, follow the steps above to thicken the potatoes. Adding a bit of warm milk or cream can help create a smoother texture.
Can I add cheese to thicken watery mashed potatoes?
Yes, cheese can be a great addition to thicken mashed potatoes, especially cheeses like cheddar, parmesan, or even a little bit of brie. However, be mindful of the added salt content and adjust seasonings accordingly.
What’s the best way to reheat thickened mashed potatoes?
Reheat thickened mashed potatoes gently over low heat on the stovetop, adding a splash of milk or cream to maintain moisture. You can also reheat them in the microwave in short intervals, stirring frequently.
Are there any herbs or spices I can add to complement the thickening process?
Absolutely! Herbs like chives, thyme, rosemary, or parsley can add flavor and complexity. Spices like garlic powder, onion powder, or a pinch of nutmeg can also enhance the taste.
What potato variety is least likely to result in watery mashed potatoes?
Russet and Yukon Gold potatoes are the least likely to result in watery mashed potatoes. Their higher starch content helps create a fluffy and absorbent texture.
How long can I store leftover thickened mashed potatoes?
Leftover thickened mashed potatoes can be stored in the refrigerator for 3-4 days in an airtight container.
Can I freeze thickened mashed potatoes?
Yes, you can freeze mashed potatoes, but the texture may change slightly. Add a little extra butter or cream before freezing to help maintain moisture. Store them in an airtight container or freezer bag for up to 2-3 months. Thaw in the refrigerator overnight before reheating.
What if I add too much potato flakes and the mashed potatoes become too thick?
If you add too many potato flakes and the potatoes become overly thick, gradually add small amounts of warm milk or cream until you reach the desired consistency. Be sure to stir well after each addition to ensure even distribution. You can also add a little bit of melted butter to help reintroduce some moisture.
