10 Make-Ahead Thanksgiving Sides That Save Time

The secret to a calm Thanksgiving is simple: do as much as possible before the big day. Make-ahead sides let you enjoy the holiday instead of spending it chained to the oven. These 10 sides can be prepped one to three days early, then reheated or finished on Thanksgiving Day — so dinner practically cooks itself.

Stuffing and Dressing

Stuffing is the king of make-ahead sides. Assemble it fully a day or two ahead — bread cubes, sautéed vegetables, herbs, broth — and refrigerate. On Thanksgiving, bake it as usual, adding a few extra minutes if it goes in cold. It reheats beautifully and tastes even better as the flavors meld overnight.

Mashed Potatoes

Mashed potatoes can be made a full day ahead and reheated in a slow cooker with a splash of cream and a pat of butter. Stir occasionally and they will be just as fluffy. Pro tip: use a ricer or food mill instead of a masher for the silkiest texture, and do not skimp on the butter.

Green Beans and Casseroles

Green bean casserole can be assembled the day before — just hold the crispy onions until baking time. Sweet potato casserole, mac and cheese, and corn pudding all follow the same rule: prep ahead, bake on the day. You will free up precious oven space and eliminate last-minute chaos.

Cranberry Sauce and Gravy

Cranberry sauce is actually better made ahead — it needs time to set and the flavors improve. Make it up to a week early. Gravy can be made two days ahead from roasted turkey parts or even a good stock; reheat and whisk in the turkey drippings on the day for fresh flavor. One less pot to juggle when it counts.

Your Game Plan

Write out a timeline: what gets made Monday, Tuesday, Wednesday. Label everything in the fridge with reheating instructions. On Thanksgiving morning, your only job is the turkey and warming the sides. Follow this plan and you will actually get to sit down — relaxed — with your guests.
