Cheesy Black Bean & Quinoa Skillet Casserole

Rachel Marek

This Southwestern-inspired one-skillet casserole is stuffed with quinoa and plenty of fresh vegetables. Sharp Cheddar cheese flavors the filling and adds a layer of ooey-gooey melted cheese on top.

Sara Haas

This healthy vegetarian casserole is a standout on any table. Crushed red pepper provides a little kick to this creamy main dish. We love the ease of jarred roasted red peppers, but if you have time, feel free to roast them yourself.

Creamy Corn Casserole with Lime, Chiles & Cilantro

Greg DuPree

If you like the Mexican corn dish known as esquites, you’ll love this creamy corn casserole. Sweet corn and tangy lime brighten up this easy casserole, while serrano chiles and cotija cheese add spice and a salty note to keep everything balanced.

Creamy Squash Casserole

This squash casserole recipe features sharp Cheddar cheese, yellow squash and a buttery, crispy cracker topping. It is key to cook down the squash in the skillet first, then drain and pat it dry as best you can so the casserole doesn’t become too watery. Yellow squash lends a pretty yellow hue, but bright green zucchini works well too.

Caprese Casserole

Sara Haas

This healthy casserole comes together easily, making it the perfect choice for any weeknight dinner. Be sure not to overcook the pasta or it will turn mushy. And don’t skip the balsamic vinegar at the end—it’s a bright finishing touch.

Summer Vegetable Tian

This pretty vegan layered casserole is so simple to make. Its only seasonings are salt and garlic-infused olive oil, which you make by sizzling a clove of garlic in olive oil for about a minute. This dish is lovely warm or room temperature. Serve with crusty bread as a vegetarian entree or alongside roasted meats as a side dish—don’t forget a glass of chilled rosé.

Stuffed Pepper Casserole

You won’t be stuffing any peppers for this stuffed pepper casserole, but you will be enjoying the sweet and smoky combination of flavors coming from bell peppers, fire-roasted tomatoes, smoked paprika and ground beef. 

Vegetarian Enchilada Casserole

Think of this vegetarian enchilada casserole as a veggie-packed Mexican-inspired lasagna with corn tortillas standing in for the noodles! If your peppers are mild and you like heat, opt for spicy pico de gallo. This easy vegetarian dinner recipe is sure to become a new family favorite.

Zucchini Parmesan Casserole

Brie Passano


This is an excellent veggie side dish for summer when zucchini is abundant. A topping of crunchy panko breadcrumbs contrasts with the delicate squash, and onion, garlic powder, Italian seasoning and crushed red pepper pack this casserole with flavor. Melty Parmesan cheese is in the mix to bring it all together.

Eggplant Tortilla Casserole

This layered casserole is inspired by classic cheese enchiladas, minus the fuss of rolling and stuffing individual tortillas. You’d never guess that within this comforting casserole hides a layer of thinly sliced eggplant. The thin slices become tender when roasted and add a subtle savory note.

Zucchini, Corn & Egg Casserole

This healthy casserole is essentially a crustless quiche, brimming with fresh summer vegetables. Bake it up for an elegant summer brunch or a casual backyard barbecue.

Herbed Tomato Gratin

Vegetable gratin recipes often have a crunchy breadcrumb or crouton topping. But summer tomatoes are too gorgeous to hide, so we tucked crusty cubes of bread underneath them instead. Plus, the bread soaks up all the juicy tomato goodness. If you can’t find marjoram, fresh basil or oregano makes a good substitute.

SSpiralized Zucchini & Summer Squash Casserole

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.

Tamari-Ginger Meatball & Eggplant Casserole

Eggplant soaks up the flavors of ginger, garlic and tamari in this casserole recipe. A hot pepper in the topping adds a bit of heat, but opt for sweet if you prefer.

Hasselback Eggplant Parmesan

The coolest way to make classic eggplant parm–and easier too! Use the hasselback technique to make partial cuts into the whole eggplant every 1/4 inch or so to fill up with melty cheese, flavorful sauce and crunchy breadcrumbs.

Summer Vegetable Chicken Tortilla Casserole

Devon O’Brien

Summer’s harvest—eggplant, corn and zucchini—stars in this healthy casserole that’s perfect for serving a crowd or for a dinner with leftovers for the next day.

Zucchini Rice Casserole

We pack extra vegetables into this cheesy baked rice casserole. Plus we substitute brown rice for white, reduce the cheese by half and swap turkey sausage for pork sausage. If you’re bringing it to a potluck, plan to reheat it before serving.

Slow-Cooker Quinoa-Summer Squash Casserole

As this layered slow-cooker squash casserole recipe cooks, the liquid from the tangy tomatillo salsa and summer squash is absorbed by the quinoa, adding tons of flavor to the final dish.

Eggplant Parmesan

Eggplant Parmesan doesn’t have to include layers of deep-fried eggplant and mountains of cheese. This healthy eggplant Parmesan is satisfying without piling on the calories and fat. 

Zucchini Gratin

This delicious zucchini gratin recipe has a delectable crispy Parmesan and breadcrumb topping and is made without any butter or cream, allowing the fresh zucchini flavor to shine. Slice the zucchini uniformly to ensure even cooking.

Chilaquiles Casserole

Our version of this enchilada-style chilaquiles casserole is packed with nutritious beans and vegetables. Canned prepared enchilada sauce has great flavor and keeps the prep time quick. It can vary in heat level so find one that suits your taste. If you want to eliminate the heat altogether, try a green enchilada sauce (which is often milder than red) or substitute two 8-ounce cans of plain tomato sauce.

Quinoa Lasagna

This healthy quinoa lasagna recipe has a layer of quinoa (rather than noodles) along with vegetables, cheese and herbs.
