Vegetable Casserole Recipes

Free up space in your oven and on the stovetop this Thanksgiving with the help of an electric pressure cooker, like the Instant Pot. Not only does it cook entirely in one pot, it cooks super-quick, perfect for a last-minute side dish.

Use any multicooker or electric pressure cooker to make this classic Thanksgiving side dish. The sweet potatoes get perfectly tender and almost caramelized while cooking under high pressure, plus using your multicooker saves stovetop and oven space.

We use flour-thickened milk combined with a modest amount of tangy sharp Cheddar to make a creamy cheese sauce for our healthy spin on the classic potatoes au gratin recipe. They're topped with additional cheese and some breadcrumbs, then baked until golden brown and bubbling. Serve the au gratin potatoes as a Thanksgiving side or with roasted chicken and vegetables for a satisfying dinner.

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.

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.

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.

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.

This dish is sure to be a kid favorite that adults will crave, too. Broccoli and cheese is a classic pairing for a reason, and when served with rice and umami-rich mushrooms, the combo is even more comforting. Garnish with shaved Parmesan and additional kosher salt and black pepper, if desired.

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.

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.

Classic eggplant Parm is filled with cheese, but this vegan eggplant Parmesan combines nondairy mozzarella cheese with nutritional yeast for a dairy-free cheesy substitute that gives you the comfort food factor without animal products. For the breading, use egg replacer, which you can find in natural-foods stores and the special-diet section of large supermarkets.

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.

Trying to lighten up your green bean casserole? Try this quick and easy salad version, which combines fried shallots, croutons, mushrooms, green beans, and chopped chard leaves for a lighter take on a holiday classic.

This version of the holiday staple uses a little bourbon to boost the flavor of the sweet potatoes, but you can also use orange juice. Baking the potatoes in their skins allows their natural sugars to caramelize for enhanced sweetness.

This cauliflower-and-broccoli gratin is healthier than traditional gratins thanks to a sauce made with low-fat milk and just enough full-flavored cheese to keep it rich without extra saturated fat and calories. For a healthier cheese-crust topping, opt for cheese crackers made without partially hydrogenated oils.

Tender strings of spaghetti squash replace pasta in this cheesy gluten-free casserole that's studded with broccoli. Cheddar cheese melts into a bubbling topping. Serve with roasted chicken or pork or as part of a vegetarian dinner.

These mini vegetarian shepherd's pies feature lentils, carrot and corn, crowned with a velvety mashed potato topping. The recipe can also be made in a broiler-safe casserole dish. Serve with a spinach salad with oranges, walnuts and red-wine vinaigrette.

This multicolored galette is a fun twist on the classic dish made with white potatoes. Don't worry if you only have one type of sweet potato, the result will still be beautiful. The bottom bakes to a potato-chip crisp with a caramelly sweetness, while the interior becomes melt-in-your-mouth rich.

This gratin dish has all of the craveable flavors of artichoke dip in a more sophisticated form. It makes a terrific side with any roasted meats or poultry.

Green bean casserole is usually built for a crowd, but not this one! It's perfectly portioned for a smaller Thanksgiving and done on the stovetop to free up oven space. Fresh breadcrumbs combined with caramelized onions deliver a savory alternative to the classic fried onions.

This easy casserole, full of ground beef, roasted broccoli and topped with hash browns, was inspired by the classic Minnesota Tater Tot hotdish. Roasting the broccoli before adding it to the casserole gives the whole dish a much more complex and exciting flavor, but it's by no means necessary. If you want to keep it simple, skip roasting the broccoli (Step 2) and use 6 cups frozen broccoli, thawed, in its place (omit 1 tablespoon oil, as well).

If you don't have a spiralizer to make this healthy zucchini noodle casserole (aka zoodles), use a vegetable peeler to make long thin strips of the squash and zucchini, stopping when you reach the seedy center. Just a few minutes under the broiler gives these ricotta-and-basil-filled nests a light golden top.

If you love sweet potato casserole, but don't have a crowd to enjoy it with, try this stuffed sweet potato "casserole" for two. One sweet potato yields the perfect amount for two people while keeping true to the classic flavors you'd expect for Thanksgiving and other holidays.

Roasted butternut squash slices layered with a creamy sauce and topped with golden breadcrumbs makes a hassle-free side dish that just about everyone loves. 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.
