Get our best Thanksgiving make-ahead casseroles.
Sorry, turkey. We're here for the sides.
Let's be real: Thanksgiving side dishes are the best part of the holiday. From decadent sweet potato casseroles to ooey-gooey mac and cheese, turkey-day side dishes are the pinnacle of comfort food. Even better? Most sides can take casserole form, which is great because casseroles tend to be less fussy and you can throw a bunch of them in the oven at once. Plus, many casseroles work well as make-ahead dishes, which can seriously trim your to-do list on the day of Thanksgiving.
We rounded up seven of our favorite make-ahead casseroles for Thanksgiving dinner, plus helpful make-ahead tips, so you can focus all of your energy on that turkey — or on all of the family members who will soon be gathering on your doorstep.
Tips for the Best Make-Ahead Thanksgiving Casseroles
- Many casseroles can be assembled a few days ahead of time then baked just before serving. To get even further ahead of schedule, make your casserole weeks in advance and freeze it unbaked.
- You can also bake a casserole complete, then freeze it—just let it cool completely first, then wrap it tightly in aluminum foil and store it in a freezer bag. If you know you'll be freezing your casserole, you can even line the pan with foil, cool and freeze, then pull out the whole frozen casserole and wrap it in foil, letting you use your casserole dish for other tasks.
- To bake a frozen casserole, transfer it to the fridge overnight to thaw, then bake the next day. If you're short on time, you can also put the frozen casserole straight into a cold oven; turn on the oven and allow the casserole to slowly heat up (if it's the sort of thing that benefits from a crisp top, just remove the foil in the last 10 minutes or so of baking).
- Always make sure to heat a casserole thoroughly before eating it; an instant-read thermometer inserted into the casserole should read 165 degrees F for safe consumption.
- Properly wrapped and sealed casseroles can be frozen for up to 6 months without damaging flavor or texture.
- Leave off the garnish until the end. If you're making a casserole that should be topped with crispy fried onions or pecan streusel, for example, wait until just before serving to add those components.
