30 Make-Ahead Casserole Recipes for Easy Weeknight Dinners (2024)

Casseroles are perfect one-dish meals and can be weeknight lifesavers—but not if you're spending an hour or more assembling them as the clock ticks closer to dinnertime. That's why we love the casseroles in this collection, which can all be made in advance and then popped into the oven (perhaps with a quick topping added first) when you're ready to eat. It's a very simple way to make a busy weeknight feel much calmer.

Be sure to read through the recipe fully before you make it, which will let you know at what point you can stop, cover the casserole, and refrigerate or freeze it before proceeding. And it's a good rule of thumb to bring any casserole up to room temperature (or close to it) before putting it into the oven. After that, all that's left to do is sit back, relax, and dig in (and congratulate yourself on your fantastic foresight!).
