Before you start freezing, you'll need to wash and peel your potatoes. Yes, it's a bit of a hassle, but trust me, it's worth it! Remove any eyes or blemishes, and give those spuds a good scrub to get rid of any dirt or debris.
Next, you'll need to cook or blanch your potatoes to inactivate the enzymes that can cause them to turn brown or become mushy. You can either boil them for a few minutes or steam them until they're slightly tender. Don't overcook them, though - you want them to still be a bit firm!
Now it's time to cool and chop your potatoes. Let them cool completely, then chop them into your desired shape - whether that's diced, sliced, or shredded. You can even make hash browns or latkes if you're feeling fancy!
