FAQs
Can I use fresh potatoes instead of frozen hashbrowns?
Yes, you can grate fresh potatoes and use them, but be sure to squeeze out excess moisture for a better texture. Frozen hashbrowns save time and provide a consistent result.
Is it possible to make this casserole ahead of time?
Absolutely. Prepare the casserole up to the point of baking, cover it tightly, and refrigerate for up to 24 hours. When ready, bake as directed, adding a few extra minutes if needed.
