You can’t just shove the whole baking dish in the fridge. That’s rookie behavior. The warm casserole will heat up everything around it, creating a bacteria breeding ground. Let it cool completely first.
Then, transfer it to an airtight container. Or cover the dish tightly with foil and plastic wrap. The goal is to keep air out. Air is the enemy of leftovers. It dries them out and invites funk.

The Reheat Revelation
Reheating is an art. The microwave works, but it turns the marshmallows into nuclear lava blobs. Better? Use the oven at 350°F. It revives the crispiness and warms the soul.
When does old casserole become dangerous? When it’s been left out on the counter for more than two hours. The “danger zone” (40°F–140°F) is where bacteria multiply like they’re at a music festival. Don’t let your casserole party alone.
