Can mashed potatoes be made ahead of time?
We don’t recommend it. While we have some tips below about reheating mashed potatoes, they will never achieve the same texture after being chilled because the starch in them will retract and firm up again (this is why we recommend keeping them warm until you serve them). However, you can prep your potatoes up to two days in advance. Store your peeled and diced potatoes in water until you’re ready to boil them.
How can you reheat mashed potatoes?
Reheated mashed potatoes aren’t going to have the same taste and texture as freshly made ones, but you can still enjoy your leftovers with these reheating techniques. First, store your mashed potatoes flattened in resealable bags with the air removed. This creates as much surface area as possible so your potatoes will reheat more evenly.
Start the reheating process by thawing a bag of potatoes in a bowl or pot of warm water. Then transfer the potatoes from the bag to a double boiler (you can create one with a metal bowl over a pot of water). The gentle heat will warm the potatoes slowly.
You can also use a microwave for this step but remember that you’ll get better results by reducing the power slightly. Putting the potatoes directly into a pot on the stove will also work, but you’ll need to add a bit of water, so they don’t dry out while heating up.
