Can You Freeze Raw Potatoes? (Answered)

You cannot freeze raw potatoes directly because they contain too much water, which makes them mushy and grainy when thawed. Blanching before freezing is necessary to preserve texture and flavor. Blanch, dry, and freeze potatoes to keep them good for later use.

My vegetable garden last year produced so many potatoes, that I didn’t know what to do with them all. After all the work my husband did, I didn’t want them to go to waste.

That would just be a shame. Have you found yourself in the same predicament? 

Maybe potatoes were on sale and now you have more potatoes than you know what to do with. The question is can you freeze raw potatoes?

Can You Freeze Raw Potatoes?

No, you cannot freeze raw potatoes. They need to be pre-cooked before freezing. 

Raw potatoes have a lot of water in them. This water will freeze and when thawed will make the potatoes mushy and grainy. 

Blanching the potatoes also kills the enzymes that cause spoiling as well as prevents the loss of flavor and nutrients.

What Is Blanching?

Blanching is a cooking method where the food is added to a pot of boiling water and cooked for a certain amount of time then quickly removed to a pot or bowl of ice water to stop the cooking process. You can also run cold water over the food. 

The vegetable/food needs to stay in the ice water or cold running water for the same amount of time you blanched it. If you blanched the vegetable for 3 minutes then the vegetable needs to be in the ice water for 3 minutes also.

You start the blanching time once the water comes back to a boil. 



Blanching and Freezing Potatoes for French Fries

I washed and peeled my potatoes and then cut them into french fries. I kept them in a big pot of cold water while I waited for my pot of water to come to a boil.  

Once my pot of water came to a boil I added my cut french fries and waited for the water to come back to a boil. Once it did I cooked the fries for 3 minutes and then quickly removed them to an ice water bath for 3 minutes.

I then dried them as best as I could, spread them on a large cookie sheet, and placed them in the freezer for about 8 hours. Once they were frozen, I removed them from the freezer, placed them into freezer bags, and returned them to the freezer.

 And that is it. Easy right? 

Well, I do have to tell you it was a lot of work but well worth it. One thing I would do differently is that I would blanch the potatoes for 5 minutes instead of the 3 minutes.  

If you would rather have sliced potatoes then you would just slice them instead of cutting them into french fries and do the same thing. Blanche, dry, and place in the freezer. 

Why put them on a cookie sheet and freeze them first? I find that when you do this, which I call flash freezing, helps to keep them from sticking together. 

What helps is making sure that you have dried them well. And when you put them on the cookie sheet make sure that they are spread out and not touching. 

If you are doing a large number of potatoes it might be best to do a few at a time. I wanted to just get it done and had too many on my cookie sheet so when I removed them from the freezer to place in bags, they had stuck together. 

Oh my, did my fingers get cold prying them apart? But you learn from your mishaps and mistakes!

I used my vacuum sealer to freeze my french fries. I love that gadget!

How Long Will They Last in the Freezer?

I have found conflicting information in my research. Some say 3 months, others say up to 6 months, and then yet again another says up to 12 months. 

I have kept mine for 1 year with no problems. I would think that it is up to you entirely. 

What you are comfortable with. I have no qualms about keeping mine in the freezer for a year. 

Of course, most will use them up before that time. But then again it all depends on how much you put in the freezer.

My Final Thoughts

• Freezing raw potatoes often results in a mushy, discolored product due to the high water content that leads to ice crystal formation, damaging the texture and flavor, similar to how freezing cucumbers or tomatoes can ruin their texture.
• Blanching potatoes before freezing can help preserve their texture and flavor, akin to the process used for freezing green beans or carrots to maintain their quality.
• The best way to freeze potatoes is to partially cook or blanch them first, then cool and freeze, mirroring the method used for preserving the quality of blanched broccoli before freezing.
• Frozen, blanched potatoes are best used in cooked dishes like soups, stews, or casseroles, much like frozen peas are typically used in cooked recipes rather than eaten raw.
• Raw potatoes can be stored in a cool, dark, and well-ventilated area for several weeks without freezing, similar to how onions and garlic are stored to prolong their shelf life.

No, you cannot freeze raw potatoes. They need to be pre-cooked by blanching before placing into your freezer. 

If you have an abundance of potatoes, whether you bought them on sale or have grown them in your vegetable garden, then freezing them is the way to go. Yes, it is a lot of work but well worth it in the end. 

“Waste not, want not” as the saying goes. Blanching is a 2 step cooking method. 

Cooking for a certain amount of time and then placing the cooked food into an ice water bath to stop the cooking method. Have you ever frozen your own french fries?
