Healthy Vegetable Casseroles
These warm and comforting veggie dishes are hearty enough to be the centerpiece of the meal, but also versatile enough to complement an array of flavors when served as a side.
First up: Here's a deliciously updated version of the classic, with fresh green beans and wine-infused mushrooms. We just had to keep the fried onion topping, which is arguably the best part.
Potato and Leek Gratin
This rustic potato side has it all – contrasting flavors, appeasing texture, and a melty, golden crust. The protein and fat present in the milk and cheese balance out the carbohydrates in the potatoes to create a satiating, diabetic-friendly side. Bonus: you can reheat the leftovers in the oven to serve with eggs and fruit the next morning for breakfast.
Cheesy Brown Rice Gratin with Zucchini and Eggplant
The walnuts in this gratin offer a crunchy contrast to the roasted vegetables and cheesy rice mixture, while the splash of half-and-half adds creamy richness. The rice mixture can be made ahead and refrigerated. When ready to prepare, bring to room temperature, spoon into the baking dish, and proceed as directed at the end of step 5.
Sweet Potato Casserole
No Thanksgiving table is complete without this sweetened vegetable. Our modern twist on the classic sweet potato casserole is a fragrant vanilla bean streusel.
Broccoli and Rice Casseroles
This cheesy casserole is bound to be a new favorite. The individual servings are fun and perfectly portioned.
This oven-baked side couples the earthiness of poblanos with the sweetness of red bell peppers. Combine those with rich pumpkin and you have a new fall-weather classic you'll make time and again.
Baked Italian-Style Cauliflower
A delightful array of ingredients come together in a magnificent way under a baked topping of crispy bread and pecorino Romano cheese.
Skillet Green Bean Casserole
We've shortened (and lightened) this holiday classic by bringing everything together in one pan and using the stovetop and broiler rather than baking.
Brussels Sprouts Gratin
Often served as a Thanksgiving side, but great for everyday use, this tasty dish is best created in stages by assembling the ingredients ahead of time and reheating before serving.
Quick Summer Squash and Bell Pepper Gratin
You could also layer sliced tomatoes in between the onion mixture and the squash and bake a few minutes longer. We like the look of a baking dish, but you could use an ovenproof or cast-iron skillet: Sauté the peppers and build the gratin in the pan, and transfer to the oven.
Tomato, Squash, and Red Pepper Gratin
Sometimes the best "steak" comes in the form of ripe, juicy beefsteak tomato slices, as in this easy gratin. Serve with a salad of fresh summer greens.
Mashed Potato Casserole
The combination of buttery Yukon gold and fluffy baking potatoes offers richness and a nice contrast both in flavor and texture. We recommend using a food mill to ensure the potatoes are evenly mashed and, just as important, not overworked, so they won't get gluey. If you don't have a food mill, cream the potatoes and cooking liquid with a potato masher.
Sweet Onion Casserole
Onions, rice, and a creamy cheese sauce make this casserole a winner in our book. We're fairly sure you'll agree.
Sweet Potato Casserole with Crunchy Oat Topping
This classic casserole often straddles the line between side and dessert (indeed, we've enjoyed the leftovers both ways). We dial down the sugar to steer the dish back to savory territory, and add a crunchy oat and nut topper for texture. A final drizzle of maple syrup just before serving gives the casserole a lovely sheen. While we call for a ricer in our master mashed potatoes, a potato masher is perfectly acceptable here since the spuds will be bound with an egg, topped, and baked. Chopped almonds or walnuts would be a delicious sub for the pecans.
Potato, Turnip, and Spinach Baeckeoffe
Translated from the Germanic Alsatian dialect, baeckeoffe means "baker's oven," as it was traditionally a dish that was brought to the local baker to cook in his oven. Classic versions are loaded with meat, but our vegetarian riff is equally hearty and rich.
Cheesy Potato Casserole
Rather than using sodium-loaded canned soup, we made our own creamy sauce to update this dish.
You can assemble the spinach and cheese casserole in less than 10 minutes by using preshredded cheeses. The casserole's spinach, cheese, and nutmeg ingredient combination produces a rich layer of flavor that everyone will love.
Sweet Potato Gratin
Evaporated milk unifies and enriches the layers of this dish. Use all sweet potatoes or mix them up. Use a loaf pan for maximum height, and bake gratin up to 2 days ahead. Rewarm, covered, in a 350° oven for 30 minutes.
Ripe Summer Tomato Gratin with Basil
Ripe tomatoes and fresh basil are essential summer companions. Here they are baked together and topped with garlicky breadcrumbs in a savory take on a fruit crumble.
Easy Corn Casserole
Making the most of convenience products, this corn casserole comes together quickly as an ideal side dish for a weeknight meal or even a holiday gathering.
Savory Turnip Gratin with Greens
Clear a place of honor on your table for this creamy and exceptionally comforting casserole.
Zesty Broccoli Casserole
This favorite casserole was revamped to include the same creamy tang of the original recipe, but with 26 fewer grams of fat. The water chestnuts add a surprising crunch, and the substitution of sharp Cheddar cheese for the milder Colby variety provides additional zing.
Zucchini and Onion Gratin
You can serve this side dish hot, but it's also great at room temperature.
Tex-Mex Hash Brown Casserole
This simple skillet dish uses shredded potatoes as a base. The potato mixture cooks on the stove top first to get it browned and crisp on the bottom. Use a cast-iron skillet to get the potatoes perfectly crusted on the bottom, then bake them with smoky chorizo under a blanket of gooey cheese.
Creamed Onion Casserole
Here's a dish of straightforward comfort, a crave-worthy combo of softened onions and leeks in a creamy sauce. Make the dish through step 2 up to a day ahead, and then reheat the next day in the baking dish.
Corn Fritter Casserole
This moist, sweet-savory side dish is a cross between corn bread and corn pudding. You can use 1 1/2 cups fresh corn kernels in place of the canned corn, if you prefer.
Streuseled Sweet Potato Casserole
A sprinkle of a buttery, brown sugar and pecan mixture over the top of the creamy potatoes in this casserole side dish make it sweet enough to be dessert.
Potato Gratin with Duxelles
Duxelles is a flavor base primarily consisting of mushrooms, onion, and leeks. It is used in meat and fish stuffings, soups, stews, and pastas. Here, it gives earthy, aromatic notes to the potato casserole.
Traditional Sweet Potato Casserole
Make everyone happy and top this lightened version of the classic sweet potato casserole with both marshmallows and toasted pecans.
Hash Brown Casserole
This simple hash brown casserole features a buttery cornflake crust and is a favorite side for both casual family gatherings and holiday celebrations.
