- It helps to save money. No more buying frozen or dehydrated hashbrowns! You can turn your leftover "trash" into 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 or Easy Hashbrown Casserole, 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.

💰 Budget-Friendly Tips
Buy in Bulk: Bagged potatoes are cheaper per pound and stretch across multiple meals.
Use Leftovers: Turn leftover baked potatoes into hashbrowns instead of buying frozen bags.
Freeze in Batches: Freeze portions in separate containers so you only cook what you need and reduce waste.
Low-Cost Flavor Boosts: Season with onion powder, garlic powder, paprika, or dried herbs for a cheap flavor upgrade.

Make Hashbrowns
Step 1: In the morning, grab your cold potatoes and run them over a cheese grater, skin and all.

Step 3: Place the baking sheet into the freezer overnight or for several hours until frozen solid.

👩🏻🍳 Expert Tips
- Adjustable Recipe: This recipe is versatile and can be scaled based on your preferences or available ingredients. Ensure the hashbrowns have ample space to freeze evenly on a baking sheet before storing.
- Space Management: For a big batch, use multiple baking sheets. This stops the potatoes from sticking together in the freezer, so you can take out as many as you need later.
❄️ Fridge, Freezer & Reheat
Fridge: Store cooked hashbrowns in an airtight container for 3-4 days.
Freezer: Keep frozen prepped hashbrowns in airtight containers or freezer bags for 2-3 months. Break apart any clumps before freezing so they cook evenly later.
Reheat: Pan-fry from frozen or thawed. Use a preheated skillet for crispier edges.
🥗 Side Dishes or Pairing Ideas
Homemade hashbrowns pair well with fried or scrambled eggs, breakfast sausage or bacon, toast or biscuits, and even simple additions like fresh fruit or yogurt. They also work great as a breakfast-for-dinner option alongside leftover proteins or whatever you already have on hand.

❓ Recipe 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.
