However, most people shy away from making them at home because they assume it is too difficult to do so. In reality, it’s not as hard as you think, especially with the right tips and tricks. There are many ways to thicken mashed potatoes because no one likes watery and thin mash. Here are some ideas on How To Thicken Mashed Potatoes.

How To Thicken Mashed Potatoes

Boiled and Mashed Potatoes

Boiled potatoes are the best when it comes to thickening mashed potatoes. You see, boiled potatoes are extremely starchy and this starch helps to thicken the gravy. While making mashed potatoes, add boiled potatoes to your mashed potatoes and you’ll find your gravy thickening and getting that wholesome taste again. But make sure to add the potatoes to your mashed potatoes at the right time. You don’t want to add potatoes to your gravy at the start of making your mashed potatoes because mashed potatoes take time.

Potato Flour

Potato flour is used to thicken gravies often and mashed potatoes are not an exception. Potato flour is gluten-free and comes in handy when you want to thicken mashed potatoes. When you add a tablespoon of potato flour to two cups of mashed potatoes, you’ll notice how the gravy thickens as you stir the potatoes. However, there is a catch. Since you’re adding something extra to your mashed potatoes, they might not taste as wholesome and delicious as they would when you use other methods to thicken mashed potatoes.

Thickened Cream

The cream thickens by itself as it comes to room temperature. You can use this thickened cream to thicken your gravy. Add some thickened cream to your mashed potatoes and stir to see the magic happen. But don’t add too much as you’ll spoil the taste. Just a little will do. Whipped cream also works for this purpose and is easier to whip up than thickened cream.

Dry Mashed Potatoes

Making dry mashed potatoes is the easiest way to thicken your gravy. You can add a tablespoon of cornstarch or a tablespoon of rice flour to a cup of mashed potatoes. Add this dry mash to the gravy and stir. You’ll notice a visible change in the texture of your gravy. The gravy will become thick and luscious. Another way to do this is to add a few tablespoons of flour and salt to a cup of mashed potatoes. Then, you can add the mixture to your gravy to thicken it up. This method tastes better because you don’t have a bunch of extra starch in your gravy.

Double Boiling

Double boiling your potatoes is one of the most authentic and traditional ways to thicken mashed potatoes. When you boil potatoes with enough water, some of the starch gets dissolved in water and forms a gel. This gel formation is used in science labs to thicken liquids and is used in households as well to thicken gravy and stews. The same phenomenon can be seen in mashed potatoes when you double boil them. Add your potatoes to a large bowl and add water to it. Boil the potatoes in water and make sure most of the water evaporates before you add the potatoes to the bowl. Then, mash the potatoes and add the rest of the ingredients to make your mashed potatoes. You’ll notice that the gravy is thicker and the potatoes are more wholesome.
