Add a thickening agent
Flour, cornstarch, or powdered milk are the most common thickening agents in people’s pantries. These are all great for quick results when thickening mashed potatoes.
Start by mixing in one tablespoon at a time until you have reached your desired consistency.
Cornstarch is the best of the three options as it has twice the thickening power. However, they will all get the job done.
Be sure to bring the mashed potatoes up to high heat to ensure that you aren’t eating raw cornstarch. It has to be cooked to be eaten.
The microwave, stove, or oven can help you to thicken your mashed potatoes as the moisture will evaporate with the heat.
In a microwave save bowl you want to place your soggy mashed potatoes uncovered in the center on high for 2 minutes.
Stir, and continue to heat them for 2 minutes at a time until you have reached your desired thickness.
It is important to stir or fluff your potatoes every two minutes to allow the moisture to release and evaporate.
Do not over mix them or they can become gummy.
Place your watery mashed potatoes into a large pot on the stove on medium-high heat.
Continue to stir the mashed potatoes every few minutes so that they don’t stick to the bottom and burn.
Use a fork when stirring the mashed potatoes and don’t over stir them as the consistency will become sticky.
Also, be sure to keep the top uncovered so that the moisture can dissolve and therefore thicken the mashed potatoes.
Much like the microwave and the stovetop the heat from the oven will help the moisture evaporate and dissolve.
In an oven-safe dish, place your runny mashed potatoes into the oven at 300°F uncovered for 10-15 minutes or until your mashed potatoes are thickened to your desire.
You won’t have to stir the mashed potatoes as the heat is consistent around the dish and will push the moisture to the top and evaporate.
Strain excess liquid
Using a cheesecloth is the best way to strain all of the excess water if your mashed potatoes are runny.
Stretch cheesecloth over your strainer pour the watery mashed potatoes over the cheesecloth and allow for them to strain.
Then pull all of the sides up together, twist the top and gently squeeze the liquid out.
Once you have as much liquid out as you can, open the cheesecloth and lay it in your strainer for about an hour to let the remaining excess moisture drip out.
Once the mashed potatoes have sat and the liquid has been removed, place them back into a pot and reheat them.
This will also remove a little more moisture to ensure that you have thickened mashed potatoes.
