How to Freeze Potatoes

Learn how to freeze potatoes the right way so they keep their flavor and texture. This step-by-step guide shows how to freeze diced potatoes, French fries, shredded potatoes for hash browns, and mashed potatoes.

Potatoes are one of the easiest crops to store for winter, especially if you grow your own. If you’re interested in growing your own harvest, see my guide on how to grow potatoes.

However, sometimes storage conditions aren’t ideal. Maybe you don’t have a cold area in your home for storing crops, or perhaps your winter turns out warmer than expected, and your potatoes begin to soften and sprout prematurely while in storage. Freezing them is a great way to preserve them before they go to waste.

Yes, you can freeze potatoes, but they need a little preparation first. Because potatoes contain enzymes that affect their color, flavor, and texture, they should be partially cooked before freezing. A quick blanch in boiling water stops these enzymes and helps the potatoes maintain their quality in the freezer.

Once prepared, frozen potatoes can be used in many different ways, from soups and stews to roasted potatoes, hash browns, and mashed potatoes.

This guide will show you how to freeze potatoes step-by-step, including diced potatoes, homemade French fries, shredded potatoes for hash browns, and mashed potatoes, so you can have them ready for quick meals anytime.

Tips for Freezing Potatoes

Freezing potatoes is simple, but a few small steps will help you get the best results. Potatoes contain a lot of starch and natural enzymes that can affect their color and texture if they aren’t handled properly before freezing.

Keep these tips in mind when preparing potatoes for the freezer:

• Keep cut potatoes in water while preparing them. Exposure to air can cause potatoes to turn gray, brown, or even black. Placing them in a bowl of cold water prevents discoloration until you are ready to blanch them.
• Blanch the potatoes first. A quick blanch in boiling water stops the enzymes that can cause discoloration and texture changes during freezer storage.
• Cool the potatoes quickly after blanching. An ice bath stops the cooking process and helps maintain a firm texture.
• Dry the potatoes well before freezing. Excess moisture can lead to ice crystals and freezer burn.
• Flash freeze before packaging. Freezing the potatoes in a single layer first prevents them from clumping together in the bag.

Best Types of Potatoes for Freezing

Most potato varieties can be frozen, but the final texture will vary depending on the variety and how fresh the potatoes are when frozen. If you are unsure how a particular variety will hold up, try freezing a small batch first before preparing a large quantity.

I have found that even slightly softened potatoes can still be worth freezing instead of wasting them. If the frozen potatoes turn out mushy when cooked, they can still work well in blended soups or mashed dishes.

Here are some common potato types and how they perform when frozen:

• High-starch potatoes (baking potatoes): These potatoes tend to freeze well because their starch helps them hold their shape after blanching. Varieties include Russet, Kennebec, Katahdin, Snowden, and Green Mountain.
• Medium-starch potatoes: All-purpose potatoes such as Yukon Gold also freeze well and work nicely for roasted potatoes, soups, and casseroles.
• Waxy potatoes: Red, white, and small new potatoes contain more moisture and less starch. They may soften slightly after freezing, but still work well in soups, stews, and skillet dishes.

Best Ways to Freeze Potatoes

The best way to freeze potatoes depends on how you plan to use them later. Preparing the potatoes in the same form you typically cook with makes it easier to pull them from the freezer and add them directly to your recipes.

Think about the types of potato dishes your family enjoys most when deciding how to prepare them for freezing.

• Diced or cubed potatoes: Freezing diced potatoes is a versatile option. The cubes can be added to soups and stews, air-fried, roasted in the oven, pan-fried for breakfast potatoes, or boiled and mashed.
• French fries: If your family enjoys oven fries or air-fryer fries, preparing potatoes as freezer fries can save time on busy weeknights.
• Shredded potatoes: Perfect for making homemade hash browns or adding to breakfast casseroles.
• Mashed potatoes: Leftover mashed potatoes freeze well and can be reheated later for an easy side dish.

Below you will find step-by-step instructions for freezing potatoes in each of these forms.

How to Freeze Potatoes Step-by-Step

Once you have decided how you want to freeze your potatoes, gather a few basic kitchen tools. You will need a large pot for blanching, bowls for cold water and an ice bath, a knife and cutting board, a vegetable peeler, and a slotted spoon or strainer.

Depending on the method you choose, you may also need a grater for shredding potatoes, baking sheets lined with parchment paper for flash freezing, kitchen towels for drying, and freezer bags or containers for storage.

The following sections walk through several ways to freeze potatoes, including diced potatoes, French fries, shredded potatoes for hash browns, and mashed potatoes. A printable recipe card with the basic method is also included at the bottom of the article.

How to Freeze Diced Potatoes

Chunks, cubed, or diced potatoes are very versatile and can be used in many dishes. Frozen diced potatoes are perfect for soups and stews, breakfast skillet potatoes, roasted potato side dishes, or even boiled and mashed later.

Step 1: Prepare the Potatoes

Scrub the potatoes well under clean running water and dry them with a kitchen towel. Fill a large bowl with cold water.

Peel the potatoes and trim away any blemishes, eyes, or green areas. Cut the potatoes into roughly 1-inch cubes, placing the pieces into the bowl of water as you work.

Cut potatoes can turn brown or gray when exposed to air. Keeping them submerged in cold water helps preserve their color until they are ready to blanch.

Step 2: Blanch the Potatoes

Bring a large pot of water to a boil over high heat. While the water is heating, prepare a large bowl filled with ice water.

Working in small batches, add the cubed potatoes to the boiling water and blanch for 2 to 5 minutes, depending on the size of the pieces and the potato variety.

The potatoes should be crisp-tender but not fully cooked. To test, pierce a piece with the tip of a knife. The knife should slide in easily with only slight resistance. If the center is still firm, cook for another minute and test again.

Use a slotted spoon or strainer to transfer the potatoes to the bowl of ice water. This stops the cooking process and helps preserve their texture.

Once the potatoes are completely cooled, drain well and pat dry with a clean kitchen towel.

Step 3: Flash Freeze the Potatoes

Line a baking sheet with parchment paper and spread the potatoes in a single layer. Place the tray in the freezer for about 1 hour, or until the potatoes are frozen.

Step 4: Package and Store in the Freezer

Once frozen, transfer the potatoes to freezer bags or containers. Remove as much air as possible, label with the date, and store in the freezer for up to 3 months.

Ways to Use Frozen Diced Potatoes

Keep the potatoes frozen until you are ready to cook them. Frozen diced potatoes can be used straight from the freezer in many recipes, making meal preparation quicker and easier.

• Oven Roasted Potatoes: Frozen diced potatoes are a great shortcut for making oven-roasted potatoes or crispy breakfast potatoes. To roast, preheat your oven to 425°F. Toss the frozen potatoes with a little oil and seasoning, spread them in a single layer on a baking sheet, and roast until the potatoes are heated through and the edges are crispy, about 15 to 20 minutes. Toss halfway through so they cook evenly.
• Air Fryer Potatoes: Frozen diced potatoes cook beautifully in an air fryer. Preheat the air fryer to 400°F. Toss the frozen potatoes with a little oil and seasoning, then cook for about 10 to 15 minutes, shaking the basket halfway through, until the potatoes are hot and lightly crispy.
• Pan-Fried Potatoes: Frozen potatoes are also a great shortcut for crispy skillet potatoes. Heat a large skillet over medium-high heat and add a tablespoon of butter or oil. Add the frozen potatoes, season to taste, and cook until heated through and golden on the edges.
• Stews and Soups: Frozen potatoes can be added directly to soups, chowders, and stews. Stir them in toward the end of the cooking time so they heat through without becoming overly soft.
• Mashed Potatoes: Mashed potatoes can also be made from frozen diced potatoes. Simply add the frozen potatoes to a pot of water, bring to a boil, and cook until tender. Drain, then mash with butter, milk, or cream and season to taste.

How to Freeze French Fries

Freezing homemade French fries is a great way to save time on busy weeknights. Preparing fries ahead of time allows you to bake or air fry them straight from the freezer.

The process is similar to freezing diced potatoes, but the potatoes are cut into fry-shaped sticks instead of cubes.

Basic steps for freezing French fries:

1. Prepare the potatoes: Scrub and peel the potatoes if desired. Cut them into evenly sized fry-shaped sticks.
2. Blanch the fries: Bring a pot of water to a boil, then blanch the cut potatoes for 2 to 5 minutes, depending on the size of the pieces. The fries should be heated through but not fully cooked.
3. Cool in an ice bath: Transfer the fries to a bowl of ice water to stop the cooking process, then drain and dry them well.
4. Flash freeze: Spread the fries in a single layer on a parchment-lined baking sheet and freeze until solid.
5. Package for storage: Transfer the frozen fries to freezer bags, remove excess air, label, and store in the freezer for up to 3 months.

For full step-by-step instructions and cooking tips, see my detailed guide on How to Freeze French Fries.

How to Freeze Shredded Potatoes for Hash Browns

Frozen shredded potatoes are perfect for quickly frying up hash browns for breakfast, adding to soups, or topping casseroles.

Step 1: Prepare the Potatoes

Wash the potatoes well under clean running water. Peel the potatoes and trim away any blemishes or green areas. Fill a large bowl with cold water.

Shred the potatoes using the large holes of a box grater. If you are freezing a large batch, a food processor with a shredding attachment can make the job quicker. Place the shredded potatoes into the bowl of cold water as you work to prevent discoloration.

Step 2: Blanch the Shredded Potatoes

Bring a large pot of water to a boil over high heat and prepare a bowl of ice water.

Working in batches, remove the shredded potatoes from the bowl with a slotted spoon and add them to the boiling water. Blanch for about 3 minutes, then transfer immediately to the ice bath to stop the cooking process.

Step 3: Dry and Freeze the Potatoes

Once the potatoes have cooled, drain them well and spread them out on a clean kitchen towel. Roll up the towel and squeeze gently to remove as much moisture as possible.

Spread the shredded potatoes in a single layer on a parchment-lined baking sheet and freeze for about 1 hour, or until frozen.

Transfer the frozen potatoes to freezer bags or containers, remove as much air as possible, label, and store in the freezer for up to 3 months.

Using Frozen Shredded Potatoes

Frozen shredded potatoes are perfect for making crispy homemade hash browns or adding to soups and casseroles.

• Skillet Hash Browns: Heat a skillet over medium-high heat and add a tablespoon of butter or oil. Add the frozen shredded potatoes in an even layer and season with salt and pepper. Cook until the bottom is golden brown and crispy, then flip or stir and continue cooking until heated through and crisp.

Freezing Mashed Potatoes

Mashed potatoes freeze very well and can be reheated later for an easy side dish.

This is a great way to preserve leftover mashed potatoes or prepare them ahead for busy weeknights.

Start by making mashed potatoes as you normally would. If you need a recipe, see my guide for Fluffy Mashed Potatoes.

For the best texture after freezing, include plenty of butter and milk or cream. The added fat helps the potatoes maintain a smooth, creamy texture once reheated.

Let the mashed potatoes cool completely, then package them into freezer bags or airtight containers in meal-sized portions. Leave about 1 inch of headspace to allow for expansion. Label and store in the freezer for up to 2 to 3 months.

Reheating Frozen Mashed Potatoes

Frozen mashed potatoes can be reheated on the stovetop, in the microwave, or in the oven. If possible, thaw them overnight in the refrigerator first to speed up reheating.

• Stovetop: Add the potatoes to a saucepan and warm over low heat, stirring occasionally until heated through.
• Microwave: Place the potatoes in a microwave-safe dish and heat on high for 5 to 8 minutes, stirring halfway through.
• Oven: Preheat the oven to 350°F. Place the potatoes in a covered casserole dish and bake until heated through, about 30 minutes.

After reheating, stir in a little extra butter, milk, or seasoning if needed to freshen the flavor.

Frequently Asked Questions About Freezing Potatoes

Freezing potatoes can raise a few questions, especially if you have never preserved potatoes this way before. Here are answers to some common questions about freezing potatoes.

Can you freeze raw potatoes?

Raw potatoes do not freeze well because they contain enzymes that continue to react even in freezing temperatures. These enzymes can cause the potatoes to darken and develop an unpleasant texture.

For best results, potatoes should be blanched briefly before freezing. Blanching stops the enzyme activity and helps preserve the potatoes’ color, flavor, and texture during freezer storage.

Do I need to peel the potatoes before freezing?

Peeling potatoes before freezing is optional. I prefer to peel them because the skins can become tough after blanching and freezing.

However, if you enjoy the texture of potato skins or want to save time during preparation, you can leave the skins on. Just be sure to scrub the potatoes well to remove any dirt before cutting and blanching.

Keep in mind that some potato varieties have thicker skins than others, so the final texture may vary depending on the type of potato you use.

Can you freeze cooked potatoes?

Yes, cooked potatoes freeze well. Mashed potatoes, roasted potatoes, boiled potatoes, and even cooked diced potatoes can be frozen for later use.

For the best texture, allow the potatoes to cool completely before packaging them in airtight freezer containers or freezer bags.

How long can you freeze potatoes?

Frozen potatoes keep their best quality for about 3 months when stored in airtight freezer bags or containers. While they may remain safe to eat longer, the flavor and texture may gradually decline over time.

Can you freeze potatoes without blanching?

Blanching is recommended before freezing potatoes because it stops the enzymes that can cause discoloration and texture changes during storage.

If potatoes are frozen without blanching, they may darken and become mushy once thawed or cooked.

Why do frozen potatoes turn brown or black?

Potatoes can darken when exposed to air or if the enzymes in the potatoes are not stopped before freezing.

Keeping cut potatoes in water before blanching and properly blanching them before freezing helps prevent discoloration and keeps the potatoes looking fresh.
