Make-Ahead Thanksgiving Side Dish Recipes

These hasselback sweet potatoes are like mini marshmallow-topped sweet potato casseroles drizzled with sage-infused butter. The hasselback technique, slicing the potato but leaving it whole, makes for a tender potato with a crispy top--the best of both worlds.

This healthy mashed sweet potato recipe has just 5 ingredients and is dinner-ready in 20 minutes. Using sweet potatoes for this classic side dish adds color to your plate along with a little sweetness and a boost of Vitamin A. With classic and simple flavors, it can easily be paired with any of your favorite dishes.

Mushrooms are a rich, meaty addition in this healthy cornbread stuffing recipe. Here we use oyster mushrooms, but you can use any variety you like. If you have time, bake the cornbread a day or two in advance so it has time to dry out a bit, which lets it absorb the flavors more readily.

Fancy up regular mashed potatoes with a layer of mushroom duxelle--a sauté of finely chopped mushrooms and shallots. We omitted the traditional butter in the duxelle and added chard for a nutritional boost. Serve this hearty side in place of mashed potatoes at any holiday feast or enjoy it as a vegetarian main dish.

These scalloped potatoes are surprisingly rich and creamy even though they're made with no dairy (milk, butter or cheese)--vegan comfort food at its best. We use almond milk, herbs and spices to make a flavorful sauce and finish the dish with a crunchy almond topping. This makes a satisfying side dish if you're cooking for dairy-free or vegan diets.

These little cute stacks are everything you want in a potato side dish: tender in the middle, devilishly crispy on the outside, and seasoned with sage and butter throughout. For best results, use a mandoline to slice the potatoes extra-thin.

Instead of loading up this comfort food side with tons of brown sugar and marshmallows, we have turned to sweet spices, vanilla and inherently sweet dried fruit to enhance the natural sweetness of the sweet potatoes. A topping of pecans and pepitas replaces traditional marshmallow topping to keep it healthy and add texture and color for a beautiful casserole.

Make this classic comfort food side dish in an electric pressure cooker, like the Instant Pot, to get the potatoes soft and tender in a jiff! This easy, 5-ingredient recipe is perfect for the holidays because it's all done in one pot and doesn't take up any extra oven or stove space.

This lightened-up take on the classic Thanksgiving sweet potato casserole is spiked with crushed pineapple and toasted pecans. We top it with an airy, slightly sweet meringue. You can pipe the meringue to make it look fancy or simply spread it neatly with a rubber spatula.

This healthy recipe is a savory riff on the traditional brown-sugar-and-pecan-topped sweet potato casserole so often found on Thanksgiving tables. Crispy baby kale leaves make a stunning garnish, but any green or herb that suits you will look great, fried or not.

This creamy spinach casserole recipe is a more sophisticated cousin to creamed spinach. It's perfect for weekend entertaining or as a holiday side dish.

What could be more satisfying than mashed potatoes? In this garlic mashed potato recipe, the potatoes are flavored with poached garlic, thinned with chicken stock and enriched with a small amount of sour cream. The recipe can easily be doubled or tripled if you're cooking for a crowd--say for Thanksgiving dinner.

Make this creamy carrot-and-parsnip casserole for your next holiday meal--everyone will beg you for the recipe! Our healthier version skips the heavy cream and butter found in most recipes--saving about 160 calories and 12 grams of saturated fat compared to a traditional version.

Simple roasted butternut squash--just tossed with olive oil, salt and pepper--makes a classic fall side dish. This recipe is delicious with roasted meats, or toss the roasted squash into pasta or salad.

A touch of cumin and cinnamon give this colorful, healthy slaw recipe a hint of the Middle East. Serve with a wedge of cheese and a whole-grain roll on the side for a satisfying dinner--or with just about anything that comes off the grill.

Frisée and radicchio are both assertive, slightly bitter greens that add color and texture to any salad. Match them with mellower-flavored greens, such as red leaf lettuce, baby spinach or even Boston lettuce.

This scrumptious sweet potato casserole gets fabulous flavor from honey and freshly grated orange zest rather than the traditional stick of butter. To complete the healthy makeover we sprinkle a crunchy pecan streusel spiked with orange juice concentrate over the top. You can save the marshmallows for s'mores.

Now everyone can enjoy classic Thanksgiving favorites, like this dairy-free green bean casserole. We make a homemade vegan cream of mushroom soup using almond milk for the creamy base that's combined with fresh green beans. Top it off with classic french-fried onions (we have a vegan recipe for that, too!) for a side dish everyone will devour.

The original version of this cheesy potato casserole stars canned soup, full-fat sour cream, a stick of butter and a crust of crushed potato chips. We lightened it considerably by using a homemade white sauce instead of canned soup and swapping nonfat Greek yogurt for the sour cream. Crushed corn flakes replace the potato chips. All in all, we slashed 200 calories, 25 grams of fat (12 grams saturated) and 170 milligrams of sodium per serving. Dig in!

This healthy update of a traditionally rich ham-and-cheese breakfast strata is made lighter primarily by losing a few egg yolks and using nonfat milk. Gruyère cheese has a delicious, nutty aroma and flavor, which means that with the relatively small amount in this recipe you still get a big impact. To finish the makeover use nutritious, fiber-rich, whole-grain bread instead of white. The results: plenty of flavor, half the calories and one-third the fat of the original.

With its pretty striped skin and uniform shape, delicata squash is a beautiful vessel for serving up this healthy quinoa stuffing. Serve this recipe as a stunning side dish or a vegetarian main with a big leafy green salad alongside.

We cook then cool the beans in advance so they can be heated up and seasoned moments before the meal. If you don't like tarragon, substitute dill or leave it out completely.

This salad was one of the favorites chosen from over 1,000 salad recipes for our 30th anniversary issue. In 2004, Deborah Madison waxed poetic about winter ingredients, particularly nuts. “In the chill air of winter, nuts move up to center stage as do their warming, substantial, golden oils--so good with winter salad greens and vegetables, such as shaved fennel, all of which are likely to end up in a salad together,” she says. Madison suggested using a mix of lettuces that balance each other here--a mild, tender variety, such as Boston, with a more intense and sturdy green, such as escarole, for instance.
