Storage/Reheating

FAQs

Can I make this casserole ahead of time?

Yes, you can assemble the casserole up to 24 hours in advance. Cover and refrigerate, then bake when ready to serve.

Do I need to thaw the tater tots first?

No, keep the tater tots frozen. They’ll crisp up perfectly in the oven while baking.

Can I use a different type of meat?

Can I freeze this casserole?

How do I prevent a soggy casserole?
