Healthy Thanksgiving Sides: 7 Lighter Classics to Make Ahead

Every Thanksgiving there’s a moment around 3 p.m. when the turkey needs the oven, the stuffing needs the oven, and somebody’s aunt is holding a casserole dish asking where it goes. Most of the stress isn’t the bird. It’s the sides. These healthy Thanksgiving sides fix two problems at once: they’re lighter than the butter-and-cream versions, and almost all of them can be made a day or two ahead, so the oven is free when you need it.

Nothing here tastes like “diet food.” The mashed potatoes still taste like mashed potatoes. The green beans still have something crispy on top. The trick is smaller amounts of butter and sugar, more vegetables per scoop, and a few smart swaps like Greek yogurt and maple syrup. Every recipe serves 8, with calories, protein and fiber per serving so you can see what’s on the plate.

1. Greek yogurt garlic mashed potatoes

Leave the skins on. You get more texture, more fiber and one less job. Greek yogurt replaces most of the butter and all of the cream, and it adds a little tang that makes the potatoes taste richer, not leaner.

• 3 lb (1,361 g) Yukon gold potatoes, scrubbed and cut in chunks
• 4 garlic cloves, peeled
• 1 cup (230 g) plain nonfat Greek yogurt, at room temperature
• 3/4 cup (180 g) 2% milk, warmed
• 2 tbsp (28 g) butter
• Salt, pepper and chopped chives

Method: Boil the potatoes and garlic in salted water until a knife slides in easily, about 15 minutes. Drain well, let them steam dry for 2 minutes, then mash with the butter and warm milk. Stir in the yogurt last, off the heat, so it stays creamy. Season and top with chives.

2. Maple roasted Brussels sprouts with pecans

This is the side that converts people who think they hate Brussels sprouts. High heat is the whole secret: the cut sides turn brown and sweet, and one tablespoon of maple syrup is enough for the whole tray.

• 2 lb (907 g) Brussels sprouts, trimmed and halved
• 2 tbsp (27 g) olive oil
• 1 tbsp (20 g) maple syrup
• 1/3 cup (35 g) pecans, chopped
• Salt and pepper

Method: Toss the sprouts with oil, salt and pepper and roast cut side down at 425°F for 20 to 25 minutes. Add the pecans for the last 5 minutes, then drizzle with the maple syrup straight out of the oven.

Per serving: 115 calories, 4.2 g protein, 12.4 g carbs, 6.9 g fat, 4.7 g fiber.

3. Green beans with mushrooms and crispy shallots

Think of this as green bean casserole without the canned soup. Browned mushrooms bring the savory flavor, and a quick parmesan breadcrumb and shallot topping replaces the fried onions.

• 2 lb (907 g) green beans, trimmed
• 8 oz (227 g) white mushrooms, sliced
• 3 shallots (120 g), thinly sliced
• 2 tbsp (27 g) olive oil, divided
• 1/3 cup (36 g) plain dry breadcrumbs
• 1/4 cup (25 g) grated parmesan

Method: Blanch the beans in boiling salted water for 3 minutes, then chill in ice water. In a large skillet, cook the shallots in 1 tbsp oil until golden and crisp, then set aside. Brown the mushrooms in the remaining oil, add the beans and toss until hot. Mix the breadcrumbs and parmesan, toast them in the empty skillet for 2 minutes, and scatter them with the shallots over the beans.

4. Sweet potato casserole with pecan oat crumble

Skip the marshmallows. Roasted sweet potatoes are already sweet, so the filling only needs 3 tablespoons of maple syrup. The oat and pecan crumble gives you the crunchy top people fight over. It’s the richest side on this list, and I think it should be: it’s a holiday, and it still has 6.3 g of fiber per scoop.

• 3 lb (1,361 g) sweet potatoes
• 2 large eggs (100 g)
• 1/2 cup (120 g) 2% milk
• 3 tbsp (60 g) maple syrup, plus 2 tbsp (40 g) for the topping
• 1 tsp cinnamon and a pinch of salt
• 1/2 cup (40 g) rolled oats
• 1/2 cup (55 g) pecans, chopped
• 1 tbsp (14 g) butter, melted

Method: Roast the sweet potatoes whole at 400°F until very soft, about 50 minutes. Scoop out the flesh and mash with the eggs, milk, 3 tbsp maple syrup, cinnamon and salt. Spread in a 9×13 dish. Mix the oats, pecans, butter and the remaining 2 tbsp maple syrup, sprinkle on top, and bake at 350°F for 30 minutes.

Per serving: 283 calories, 6.1 g protein, 47.7 g carbs, 8.3 g fat, 6.3 g fiber.

5. Orange maple cranberry sauce

Homemade cranberry sauce takes 15 minutes and lets you decide how sweet it is. Orange juice does part of the sweetening, so 1/3 cup of maple syrup covers a full 12 oz bag of berries.

• 12 oz (340 g) fresh or frozen cranberries
• 1/2 cup (124 g) orange juice
• 1/3 cup (105 g) maple syrup
• Zest of 1 orange

Method: Simmer everything in a saucepan over medium heat, stirring now and then, until most berries pop and the sauce thickens, 10 to 12 minutes. It sets more as it cools. One serving is about 1/4 cup.

Per serving: 61 calories, 0.3 g protein, 15.5 g carbs, 0.1 g fat, 1.6 g fiber.

6. Whole wheat herb stuffing

Classic stuffing soaks up a lot of butter. This one uses a mix of olive oil and a little butter, plenty of onion, celery and mushrooms, and low-sodium broth for moisture. Whole wheat bread holds its shape better than white, so the stuffing stays tender instead of turning to paste.

• 12 oz (340 g) whole wheat bread, cut in 1-inch cubes (about 10 slices)
• 2 tbsp (27 g) olive oil and 1 tbsp (14 g) butter
• 1 onion (150 g), diced
• 3 celery ribs (120 g), diced
• 8 oz (227 g) white mushrooms, chopped
• 1 1/2 cups (360 g) low-sodium chicken broth
• 1 large egg (50 g)
• 1 tbsp chopped fresh sage, 2 tsp thyme, salt and pepper

Method: Toast the bread cubes at 350°F for 15 minutes until dry. Cook the onion, celery and mushrooms in the oil and butter until soft, about 10 minutes, then add the herbs. Whisk the broth and egg, pour over the bread and vegetables in a large bowl, and fold together. Bake covered at 350°F for 25 minutes, then uncovered for 15 more until the top is crisp. For a vegetarian table, use vegetable broth.

Per serving: 181 calories, 8.2 g protein, 21.9 g carbs, 7.3 g fat, 3.4 g fiber.

7. Roasted butternut squash and kale with feta

Every Thanksgiving table needs one side that isn’t beige. This warm salad sits fine at room temperature, which makes it perfect for a buffet, and the pepitas and feta keep it interesting.

• 900 g peeled butternut squash cubes (from one 2 1/2 lb squash)
• 1 bunch kale (200 g), stems removed, chopped
• 2 tbsp (27 g) olive oil
• 1 tbsp (20 g) maple syrup
• 1/3 cup (45 g) pepitas
• 1/3 cup (50 g) crumbled feta

Method: Toss the squash with most of the oil and some salt and roast at 425°F for 25 to 30 minutes. Massage the kale with the remaining oil and a pinch of salt for 1 minute. Toss the hot squash with the kale and maple syrup, then top with pepitas and feta.

Make-ahead plan for healthy Thanksgiving side dishes

Here’s the order I’d follow so Thursday is mostly reheating. If you already batch-cook on Sundays, this will feel familiar; if not, the basics in our meal prep for beginners guide apply here too.

1. Sunday or Monday: Make the cranberry sauce and refrigerate it. Cube and dry out the bread for the stuffing, then store it in a paper bag.
2. Tuesday: Make the mashed potatoes and the sweet potato filling (without the crumble). Blanch the green beans, trim the Brussels sprouts, and mix the crumble topping in a separate container.
3. Wednesday: Roast the squash, cook the stuffing vegetables, and assemble the stuffing without baking it. Cook the crispy shallots and keep them at room temperature in a sealed container.
4. Thursday: Bake the stuffing and sweet potato casserole while the turkey rests. Roast the Brussels sprouts at the end, finish the green beans on the stove, and reheat the mashed potatoes over low heat with a splash of milk.

How to make Thanksgiving sides healthier without anyone noticing

• Cut the butter, don’t remove it. One or two tablespoons per dish keeps the flavor people expect.
• Roast instead of boiling vegetables. Browning adds sweetness, so you need less sugar and cheese.
• Keep the crunch. Toasted nuts, breadcrumbs and pepitas make a lighter dish feel like a treat.
• Add one big green side. It fills half the plate and balances the richer dishes. If you want even more ideas, our high fiber meals use the same vegetable-forward approach.

How long do Thanksgiving leftovers last?

FoodSafety.gov’s cold food storage chart lists 3 to 4 days in the refrigerator for leftovers like cooked poultry and soups, and that’s the window I use for these sides too. Store them in shallow containers so they cool quickly. Leftover squash and kale makes a good lunch bowl with some sliced turkey, and once the holiday food is gone, our healthy fall dinners keep the season going on weeknights.

Hosting a vegetarian guest? Our stuffed acorn squash makes an easy centerpiece (swap the turkey for lentils), and the healthy apple crisp is a lighter dessert that bakes while you eat.
