A frozen casserole is the perfect solution to a busy day. Just thaw it in the fridge in the morning, and reheat in the oven for dinner that night. Easy breezy.


If the frozen casserole is in a glass container, check that the manufacturer instructions say it's safe to put in the oven while cold. If not, or if you're unsure, carefully transfer the frozen casserole into an oven-safe baking dish.

Preheat the oven to 350 degrees Fahrenheit.

Place the casserole in the oven and heat until it reaches an internal temperature of 165 degrees Fahrenheit. (You can check the temperature with a meat thermometer.)

Remove the casserole once it's hot. Dinner is served!
