Make-Ahead Thanksgiving Side Dish Recipes

If you're looking for a twist on classic scalloped potatoes, this recipe using roasted sweet potatoes and melty Gruyère has all the creaminess of the original with a new flavor twist. The sweet potatoes and lightened sauce--made with flour and low-fat milk--keep it healthier than butter- and cream-laden versions. Don't cut your sweet potatoes too thin--they'll turn mushy under the sauce.

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.

Serve this hearty and healthy fall salad with roasted pork tenderloin, chicken or salmon, or with your Thanksgiving meal.

Cranberries add a sweet-tart edge, while the maple-tahini dressing provides depth.

The cheesy-seedy crust that tops this healthy cauliflower casserole recipe evokes everything bagels. Serve for the holidays or as a hearty side dish with roast chicken.

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.

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.

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.

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.

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.

Sizzling green beans in a little oil helps to bring out their natural sweetness. Prosciutto, pine nuts and lemon zest dress up the flavor without adding a lot of fat--a nice alternative to full-fat, creamy green bean casseroles.

These baked onions are stuffed with a savory combination of mushrooms, breadcrumbs and capers.

Contrasting sweet grapes with savory feta cheese and crisp, colorful greens, this salad makes an elegant first course.

Whole roasted carrots make quite a statement on the dinner table when they're topped with a port wine-and-fig dressing. In this recipe, we like dried Calimyrna figs because they're a tad less sweet than Mission figs and taste slightly nutty as well.

This crab-cake-meets-stuffing recipe gets a double dose of crabby goodness--little bits of claw crabmeat add flavor throughout the stuffing while pieces of higher-grade “jumbo lump” crabmeat contribute big bites of crab. Shape the stuffing into cakes or bake in a casserole dish. Look for crab in the seafood department of large supermarkets. The recipe that's included for Bay Spice Blend makes 1 cup, but you'll only need 1 teaspoon for the stuffing. Try the extra spice blend in a turkey brine, sprinkled on almost any type of seafood and/or in recipes calling for Old Bay Seasoning.

Cutting vegetables into long thin strips--a technique called julienning--rather than shredding them gives this healthy slaw recipe a marvelous, crisp texture. You can cut the vegetables by hand, but a mandoline will save you a lot of time. If your radishes still have the greens attached, reserve them and use as a garnish.

This scrumptious sweet potato casserole gets fabulous flavor from honey and freshly grated orange zest rather than the traditional stick of butter.
