Classic Thanksgiving Side Dishes Ahead of Time

Use these reliable bases so the food reheats like it was cooked today.

Silky Make-Ahead Mashed Potatoes

Boil and mash with butter and warm cream. Chill fast in shallow containers. On Thursday, reheat gently with warm milk, stirring until smooth. Salt at the end.

Herby Bread Stuffing (Crisp Top, Soft Middle)

Dry bread matters. Assemble Wednesday, bake to set, cool, and refrigerate. Reheat covered; uncover last 10 minutes to re-crisp. Add sausage or mushrooms for depth.

Green Bean Casserole, But Fresh

Blanch green beans Tuesday. Make mushroom sauce Wednesday. Combine and bake, then chill. Reheat covered; add fried onions at the very end so they stay crisp.

Sweet Potato Casserole (Not Candy)

Mash roasted sweet potatoes with butter, a touch of maple, and salt. Bake Wednesday. Reheat covered and finish with pecan-oat crumble or toasted marshmallows.

Mac and Cheese That Stays Creamy

Undercook pasta 1–2 minutes. Make it extra saucy before chilling so it won’t dry out. Reheat covered; broil for 2 minutes for a golden top.

Easy Thanksgiving Vegetable Sides (Sheet-Pan Wins)

Sheet-pan veg reheat like champs and double as quick Thanksgiving recipes.

Roasted Brussels + Carrots

Par-roast Wednesday. On Thursday, toss with maple-mustard glaze and broil 2–3 minutes.

Brown Butter Green Beans with Almonds

Toast almonds Monday. Blanch beans Tuesday. Thursday, warm in brown butter with lemon. Fast, bright, and fresh.

Herb-Roasted Squash

Par-roast with olive oil and rosemary. Finish with a drizzle of balsamic and flaky salt at service.

Freezer-Friendly Holiday Sides

Batch now, thank yourself later. These freezer friendly holiday sides hold texture and flavor.

Make-ahead gravy: Roast turkey wings or chicken parts earlier in the week, build a rich stock, thicken, and freeze. Reheat while the bird rests.

Cornbread: Bake, cool, and freeze. Thaw for stuffing or serve warm with honey butter.

Cranberry sauce: Freezes well; thaw in the fridge for perfect texture.

Rolls: Par-bake, freeze, then finish in a hot oven for fresh-baked vibes.

Best Side Dishes for Thanksgiving (Fast Upgrades)

• Keep the fridge at 40 °F or below.
• Reheat sides to an internal 165°F before serving.
• Label containers by dish + date.
• Reheat casseroles first; they hold heat while you finish veg. These are the non-negotiables that make holiday side dish recipes feel fresh even when cooked days ago.

Sample Reheat Schedule (90 Minutes)

• T-90: Casseroles in, covered (325–350 °F)
• T-45: Sheet-pan veg on middle rack
• T-15: Uncover casseroles to crisp tops; broil if needed
• T-10: Warm gravy; final herb garnish
• T-0: Plate, temp-check 165 °F, serve

Quick Tips

• Keep one oven rack free for reheating waves
• Warm serving bowls so food stays hot longer
• Use sheet pans as staging to move multiple sides at once
• Salt after reheating; flavors bloom at the end
• Park a thermometer on the counter as a reminder
