Scalloped Sweet Potatoes

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.

Vegan Green Bean Casserole

Now everyone can enjoy classic Thanksgiving favorites, like this dairy-free green bean casserole.

Apple-Cranberry Stuffing

Apple-Cranberry Stuffing

Make this stuffing with an apple variety that holds its shape rather than turns to sauce during the cooking process, so there will be tender bites of fruit throughout. Honeycrisp, Granny Smith or Pink Lady are all easy-to-find options.

Rutabaga and/or celeriac give this casserole a more nuanced flavor, but you could also use turnips or kohlrabi—or make it with all potatoes instead.

No-Sugar-Added Sweet Potato Casserole

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.

Slow-Cooker Green Bean Casserole with Crispy Onions

Thanks to fresh green beans, an easy homemade cream sauce and crispy onion topping, this green bean casserole recipe is healthier and more delicious than traditional recipes that use canned soup, beans and onions. Plus, the slow cooker saves you time cooking at the stove. Make sure to use fresh green beans, as frozen green beans will become mushy.

Vegan Scalloped Potatoes

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.
