Have you ever wondered what to do with leftover baked potatoes? Twice-baked potatoes might be a good idea, but a great idea is making your own frozen hashbrowns!

Once you learn how to make frozen hashbrowns you'll never want to buy storebought again. It's so simple and easy that it's almost laughable to think what you paid for convenience in a bag. Save money and make shredded hashbrowns at home whenever you want.
I love making frozen shredded hash browns because no one around here eats leftover baked potatoes. I always make a few too many when I make Oven Baked Potatoes because you never know when someone is going to want another one.
And because I love to repurpose leftovers, I also secretly hold out hope that no one wants more just so that I can make and prep hashbrowns for the weekend.
Why This Recipe Works
- It helps prevent food waste. Baked potatoes are only good reheated so many times, and they're often dry when you do so anyway. By making hashbrowns, you're giving those unwanted spuds a chance at a new life.
- It helps to save money. No more buying frozen or dehydrated hashbrowns! You can turn your leftover "trash" onto treasure and save money in the process.
- You can use them however you want. Later, when you want crispy breakfast hashbrowns or you want shredded potatoes for your Cheesy Potato Soup, you can just grab what you need from the freezer bag and use it as desired. So many possibilities!
🥘 Ingredients
Baked Potatoes- In reality, they could have been baked, microwaved, or even boiled. What's important is that they were cooked all of the way through and then cooled overnight in the fridge so that they can be firm and easy to handle.
Butter- You will need butter when it is time to cook the hashbrowns, but not before.
Seasonings- When you go to cook the hashbrowns, you can add any seasonings of your choice.

🔪 Instructions
Check out how to Make Frozen Hashbrowns with these simple step-by-step instructions:
Bake Potatoes (if needed)
Wash and scrub your russet potatoes well. Pierce them with a fork several times.
Rub the potatoes in olive oil and sprinkle on some salt and pepper.
Bake at 425 degrees F on a baking sheet for 45 minutes or until fork-tender.
Let cool and then place in the fridge overnight to chill.
Make Hashbrowns
In the morning, grab your cold potatoes and run them over a cheese grater, skin and all.
Spread the grated potatoes over a parchment paper lined baking sheet into a nice and even layer.
Place the baking sheet into the freezer overnight or for several hours until frozen solid.
Break up the potatoes so that there are no large clumps and then place them into an airtight container in the freezer. Label it if needed.
Cook Homemade Frozen Hashbrowns
Heat a skillet to medium-high heat and then add in the butter. It's important to preheat your skillet before adding the potatoes.
Once the butter has melted, add your hashbrowns to the pan. Cook for about 5 minutes, until golden brown, and then flip and cook the other side for about 5 more minutes.
Season your hashbrowns as desired.
Remove from skillet and serve.
🍴 Recipe Tips
This recipe can be scaled depending on what you have on hand or how many hashbrowns you want to make. Just make sure to allow the hashbrowns to have space to freeze in an even layer on a baking sheet before storing.
So if you make a bunch, you may need more than one baking sheet. This step helps to prevent the potatoes from sticking together in the freezer, making it easier to grab your desired amount before using.
💭 FAQs
Once frozen and placed into an airtight container your hashbrowns are good for up to 6 months. Just grab what you need and use it whenever the mood strikes. Once cooked, leftover hashbrowns can be stored in the fridge for up to 4 days.
Getting your skillet nice and hot helps, so make sure to preheat it before adding anything to the pan. You want the temp to be about medium high. Melt butter or olive oil in the skillet until it begins to sizzle. Add your frozen hashbrowns to the pan and cook for about 5 minutes until the bottom of the hashbrowns is golden in color and then flip. Cook the other side for another 5 minutes and remove from heat.
I don't recommend it. This recipe works best with russet potatoes because they're extra starchy and fluffy. Other potato varieties will not turn out the same.
