How long are leftover mashed potatoes good for? If you have a container staring at you from inside your refrigerator and you don’t know whether to toss or eat this yummy side dish.. read on!
I can’t think of a more comforting food than mashed potatoes off the top of my head. They are so creamy, dreamy, buttery and versatile. Any holiday or dinner table is instantly made better when they are present. I love them so much.
My mom made this irresistible side dish a lot growing up. It’s not just for Thanksgiving dinner! It was a dinner staple in our house. She never once opened a package of instant potatoes and I’m forever grateful for that!
When I left home I desperately missed this creamy side, so I learned how to make it myself. No matter how many times I try, they’re never as good as my mom’s. It’s the mom magic!
The only (and I truly mean only) “bad” thing about making them is that it is so hard to gauge how many leftovers are about to invade your fridge. I have literally never made this dish and not had leftovers. Which isn’t a terrible thing because they are easy to reheat and eat later.
But if you have a dish filled with them staring at you from inside your refrigerator, you may not remember how long they’ve been there or whether they are worth heating up again. Read on for tips about how to know if your leftovers are still good or if you should toss them.
How Long Are Leftover Mashed Potatoes Good For In The Fridge
When stored properly in an airtight container or tightly covered baking dish, cooked potatoes will last for up to 5 days in the refrigerator.
When reheating, keep in mind that you may need to revive the potato dish by adding extra milk (1-2 tbsp at a time) or a small amount of butter.
Extend the Shelf Life
- Refrigerate them. As soon as you deem them “leftovers,” place them in a sealed container and store them in the fridge to maintain the best quality. Minimize their time at room temperature as much as possible.
- Ensure the container is sealed. Making sure the container they’re stored in is air tight or very tightly covered with aluminum foil or plastic wrap will keep them from drying out and will keep moisture buildup from happening (which can shorten their lifespan). Resealable plastic bags are another great storage option that will keep them fresh for an optimal amount of time.
- Freeze them. Instead of storing potatoes in the fridge, popping them in the freezer is a great way to extend the shelf life even further. Before storing, allow them to fully cool to room temp and separate them into sections so it is easier to thaw them. Place in doubled freezer bags or shallow airtight containers. Freeze for up to 12 months.
How To Know If Leftover Potatoes Have Gone Bad
If you find yourself inspecting your dish of fluffy pots, trying to figure out whether or not it has been sitting in the fridge for too long, there are a few ways to determine whether you should toss or eat.
- Discoloration or mold. The best way to determine if they’re past their prime is to detect discoloration or moldy splotches. This can be a sign of growth of bacteria and may cause food poisoning if consumed.
- Smell test. If the potatoes have a sour or off smell, this could be a sign that they are past their prime and should not be consumed.
- Taste test. If steps one and two pass the test, give the pots a quick taste test. If anything is amiss, follow your gut and throw them away.
