The turkey gets the attention, but the sides are what make Thanksgiving feel generous. They are also what crowds the stove on the day. The fix is simple: cook most of them in advance. These make-ahead Thanksgiving side dishes can be prepared one to three days before Thursday, November 26, 2026, then reheated while the turkey rests, so you can actually sit down with your guests.
Make-Ahead Thanksgiving Side Dishes: Your Timeline
- Saturday or Sunday (Nov 21-22): shop, make cranberry sauce, and dry out bread cubes for stuffing.
- Tuesday (Nov 24): make mashed potatoes and the sweet potato filling. Blanch green beans.
- Wednesday (Nov 25): assemble the green bean casserole and stuffing, cover and chill. Trim Brussels sprouts.
- Thursday (Nov 26): reheat and bake while the turkey rests. Roast the sprouts last.
Each recipe below serves 8 to 10 as part of a full spread.
1. Creamy Make-Ahead Mashed Potatoes
Cream cheese and butter keep these potatoes soft after a day in the fridge.
- 3 lb (1.4 kg) Yukon Gold potatoes, peeled and cut into chunks
- 1/2 cup (115 g) butter
- 4 oz (115 g) cream cheese, softened
- 3/4 cup (180 ml) warm whole milk, plus extra for reheating
- 1 1/2 tsp salt and black pepper to taste
- Cover the potatoes with cold salted water, bring to a boil and simmer 15 to 20 minutes until very tender.
- Drain well, return to the pot for a minute to steam dry, then mash with butter, cream cheese and milk. Season.
- Spread in a buttered baking dish, cool, cover and chill for up to 2 days.
- To reheat, stir in a splash of milk, cover with foil and bake at 350F (175C) for 30 to 40 minutes, stirring once.
2. Green Bean Casserole from Scratch
- 1 1/2 lb (680 g) fresh green beans, trimmed and halved
- 8 oz (225 g) mushrooms, sliced
- 3 tbsp butter and 3 tbsp all-purpose flour
- 1 cup (240 ml) chicken or vegetable broth
- 1 cup (240 ml) whole milk
- 1 garlic clove, minced, plus salt and pepper
- 1 1/2 cups (about 85 g) crispy fried onions

3. Herb and Celery Stuffing, Baked in a Dish
Baking stuffing in a separate dish rather than inside the bird is easier to time and safer to cook through.
- 1 lb (450 g) sturdy white or sourdough bread, cut into cubes
- 1/2 cup (115 g) butter
- 1 large onion and 3 celery stalks, diced
- 2 tbsp chopped fresh sage, or 2 tsp dried
- 1 tbsp fresh thyme leaves
- 2 1/2 cups (600 ml) broth and 2 large eggs
- Leave the bread cubes out overnight, or dry them in a 300F (150C) oven for 20 minutes. Store in a bag for up to 3 days.
- Soften the onion and celery in butter for 8 minutes, then add the herbs.
- The day before, toss bread with the vegetables, whisk the eggs into the broth and pour over. Press into a buttered dish, cover and chill.
- Bake covered at 375F (190C) for 30 minutes, then uncovered for 15 to 20 minutes until golden and 165F (74C) in the center.
4. Orange Cranberry Sauce
- 12 oz (340 g) fresh or frozen cranberries
- 3/4 cup (150 g) sugar
- 3/4 cup (180 ml) orange juice and the zest of 1 orange
- A pinch of salt and 1 cinnamon stick (optional)
Simmer everything for 10 to 12 minutes until most berries burst. It thickens as it cools. Chill in a covered jar for up to a week and serve cold or at room temperature.
5. Maple Sweet Potato Bake
- 3 lb (1.4 kg) sweet potatoes
- 1/4 cup (60 ml) maple syrup and 4 tbsp (55 g) melted butter
- 1/2 tsp cinnamon, 1/2 tsp salt and 2 eggs
- Topping: 3/4 cup (85 g) chopped pecans, 1/3 cup (70 g) brown sugar, 1/4 cup (30 g) flour and 3 tbsp butter
- Roast the whole sweet potatoes at 400F (200C) for 45 to 60 minutes until soft. Scoop out the flesh and mash with the syrup, butter, cinnamon, salt and eggs.
- Spread in a dish, cover and chill for up to 2 days. Keep the topping in a separate bag.
- On the day, scatter the topping over and bake at 350F (175C) for 35 to 40 minutes until hot and crisp on top.
6. Roasted Brussels Sprouts with Balsamic
Trim and halve 2 lb (900 g) Brussels sprouts the day before and store them in a bag. On Thursday, toss with 3 tbsp olive oil, salt and pepper, and roast at 425F (220C) for 20 to 25 minutes. Finish with 1 to 2 tbsp balsamic glaze. Roasting is best done fresh, but the prep is what saves you time.
Food Safety for Make-Ahead Sides
- Cool cooked food quickly and refrigerate within 2 hours. Shallow containers cool faster than deep pots.
- Keep your fridge at 40F (4C) or below. Clear space early in the week.
- Reheat sides until they reach 165F (74C) in the center. An instant-read thermometer takes the guesswork out.
- Do not leave food on the table for more than 2 hours. Refrigerate leftovers and eat them within 3 to 4 days.

FAQ
How far ahead can I make Thanksgiving sides?
Cranberry sauce keeps up to a week. Mashed potatoes and sweet potato bakes are good for 2 days. Assembled casseroles and stuffing are best made one day ahead.
How do I reheat several sides with one oven?
Most of these reheat at 350F to 375F (175C to 190C). Bake them while the turkey rests, which should be at least 30 minutes, and use a slow cooker for the potatoes.
A calm Thanksgiving starts on the weekend before. Make the cranberry sauce early, get the potatoes and casseroles into the fridge by Wednesday, and leave only the reheating and a tray of sprouts for the big day. Your guests will enjoy the food, and you will get to enjoy it with them.
