Tips for Using Leftover Mashed Potatoes
- Remember proper storage is key for your potatoes. Use an airtight container and keep them on the highest shelf in your fridge. You can store them for up to four days.
- Freeze mashed potatoes if you have too much. Potatoes don’t typically freeze well, but mashed potatoes are the exception. Scoop into a freezer-safe bag and freeze for up to 6 months.
- Defrost by placing the mashed potatoes in the refrigerator and thawing overnight. If you want to speed things up, you can gently reheat on the stovetop or in the oven, slow cooker, or microwave.
- Add some fat. Stir in some sour cream or cream cheese to give them a thicker, more creamy, consistency after reheating. This helps for however you might be using the potatoes.

Frequently Asked Questions
Absolutely! Most of these recipes with leftover potatoes can be made with mashed sweet potatoes instead, lending a hint of sweetness to your dishes. I recommend that you adjust the seasoning to balance the natural sweetness.
That would vary on the ingredients in the particular recipe, depending on what the mashed potatoes are whipped with. However, most mashed potatoes are good for up to 4 days, provided they are stored in an airtight container in the refrigerator.
Gradually add a little bit of warm liquid like milk, cream, or broth and gently reheat on the stovetop or the microwave in short intervals. Be careful not to add too much liquid, as that will make the potatoes runny, but just enough to get a creamy texture.
