FAQs

Can I make this casserole ahead of time?

Can I use fresh potatoes instead of frozen hashbrowns?

Yes, just shred and rinse them thoroughly, then pat dry before using.

What type of sausage works best?

Breakfast sausage is traditional, but you can use spicy Italian, turkey, or chicken sausage too.

Can I omit the cheese?

Is this dish gluten-free?

Can I bake this in a smaller dish?

Why is my casserole watery?

Excess moisture from vegetables or undercooked hashbrowns can cause this. Sauté vegetables first and drain them well.
