How to Freeze Mashed Potatoes

Mashed potatoes are a delicious and versatile dish that can be enjoyed as a side or even used as an ingredient in other recipes.

If you find yourself with leftover mashed potatoes or want to prepare them in advance, freezing is a great option to preserve their flavor and texture.

In this article, we will guide you through the process of how to freeze mashed potatoes, from preparation to storage and reheating.

How to Prepare Mashed Potatoes for Freezing

Before freezing mashed potatoes, it’s essential to prepare them properly to maintain their quality:

Choose the Right Potatoes: Opt for starchy or all-purpose potatoes like Russet or Yukon Gold, as they result in fluffier and creamier mashed potatoes.

Cook and Mash: Boil the potatoes until they are tender, then drain them thoroughly. Mash the potatoes using a potato masher or a ricer until they are smooth and free of lumps.

Add Ingredients: If desired, add butter, milk, cream, or any seasonings to the mashed potatoes to enhance their flavor. Be aware that some ingredients may affect the texture after freezing and reheating.

Portioning the Mashed Potatoes

Portioning the mashed potatoes before freezing makes it easier to thaw and reheat only the amount you need. Consider these options:

Individual Servings: Scoop the mashed potatoes into individual serving-sized containers or freezer-safe bags. This allows you to take out one serving at a time without defrosting the entire batch.

Family-Sized Portions: If you prefer to freeze larger quantities, divide the mashed potatoes into family-sized portions suitable for your needs.

Freezing Mashed Potatoes

Follow these steps to freeze mashed potatoes properly:

Cooling: Allow the mashed potatoes to cool completely at room temperature before freezing. This helps prevent excess moisture and ice crystal formation.

Airtight Containers: Transfer the mashed potatoes into airtight containers or heavy-duty freezer bags. Ensure that the containers or bags are sealed tightly to prevent freezer burn and the absorption of odors.

Labeling: Label each container or bag with the date of freezing. This will help you keep track of their storage time and ensure you use them within a recommended timeframe.

How Long Can Mashed Potatoes Be Frozen?

When stored at 0°F (-18°C) or below, mashed potatoes can be frozen for up to 2-3 months. While they may still be safe to eat beyond this timeframe, the quality and taste may deteriorate over time.

Thawing and Reheating Mashed Potatoes

When you’re ready to enjoy your frozen mashed potatoes, follow these steps for thawing and reheating:

  • Refrigerator Thawing: Transfer the desired portion of frozen mashed potatoes from the freezer to the refrigerator. Allow them to thaw overnight or for approximately 24 hours. Thawing in the refrigerator helps maintain the texture and prevents bacterial growth.
  • Reheating Options: There are several methods for reheating mashed potatoes, including:
    • Stovetop: Transfer the thawed mashed potatoes to a saucepan and heat over low to medium heat, stirring occasionally until they are heated through. Add a splash of milk or broth to restore creaminess if needed.
    • Microwave: Place the thawed mashed potatoes in a microwave-safe dish and heat in short intervals, stirring in between, until they are fully reheated. Be cautious not to overcook, as this can lead to dryness.
  • Stirring and Adjustments: Stir the reheated mashed potatoes to ensure an even temperature and consistency. If needed, add additional butter, milk, or seasonings to enhance the flavor.

Quality Check

Always assess the quality of thawed and reheated mashed potatoes before consuming. Discard them if you notice any off-putting odor, unusual discoloration, or texture changes.


By following these guidelines, you can freeze mashed potatoes and have a convenient supply of this beloved dish whenever you need it. Whether for meal prep or utilizing leftovers, freezing mashed potatoes allows you to enjoy their creamy goodness for an extended period.
