How long can you keep leftover Hamburger Potato Casserole in the fridge?

You can safely store leftover casserole in an airtight container in the refrigerator for about 3-4 days. After that, the texture and flavor may begin to degrade.

Can you freeze Hamburger Potato Casserole, and if so, how long will it last?

Yes — you can freeze this casserole either before or after baking. Properly wrapped and sealed, it will keep well for up to 2-3 months in the freezer. For best texture, defrost in the fridge before reheating.

What potatoes work best for this casserole so they don’t turn mushy?

Using a starchier potato like russet or a firm Yukon gold helps maintain structure during baking. Slicing them about ¼-inch thick and keeping uniform size ensures even cooking and avoids a mushy layer.
