Tips

Make-ahead: You can assemble the casserole, cover it with foil, and refrigerate it for up to 24 hours before baking.
Freezing: Cool the casserole completely, then wrap tightly in foil and place in a freezer-safe container. Freeze for up to 3 months. Thaw in the refrigerator overnight before reheating. Freeze the casserole without the chips on top to prevent them from getting soggy.
