Vegetarian Casseroles

A veggie casserole is a great addition to any meal, and you can easily bring one along for any potluck or family holiday meal you’ve got coming up.

“Casseroles” might get a bad rap for being boring and tasteless, but these vegetarian casserole recipes are packed with flavor.

Whether you’re looking for a healthier version of a classic casserole dish or something entirely new, you’ll find what you’re looking for.

1. Vegetarian sausage casserole

This simple Vegetarian Sausage Casserole packs a lot of flavors! I love the smoky paprika used in this.

This is one of my favorite things to make when I’m short on time but want something warm and filling.

Frozen veggie sausages are the key ingredient in this casserole. You can pick whatever your favorite brand is to really make something suited to your tastes. It’s great with any kind of bean, so don’t worry if you haven’t got the butter beans the recipe calls for.

2. Vegan Blueberry French Toast Casserole

Are you looking for something sweet and sugary that’s still good for you? This Vegan Blueberry French Toast Casserole should definitely hit the spot!

The recipe uses gluten-free bread and applesauce, so it’s great for anyone who is gluten-free, dairy-free, and egg-free as well.

You won’t feel like you’re missing out on anything because of how delicious this is.

If you’re a fan of bread pudding-like I am, you’ll love this dish. Pour some syrup on top and enjoy all the crispy blueberry goodness.

3. Enchilada Casserole

This is one of my favorite meatless casserole recipes. Enchilada Casserole sure hits the spot any time I have a craving for Mexican food, and it’s so easy to make!

The roasted veggies make this casserole hearty and filling. I use cauliflower, sweet potato, bell peppers, and onions, but you can switch things up and use whatever vegetables call.

This casserole is a great dish to bring to a potluck or other event.

You can eat it on its own or serve it with Spanish rice.

4. Vegetarian Breakfast Casserole

I’m a huge fan of easy vegetarian casseroles that I can customize and adjust to my preferences. This Vegetarian Breakfast Casserole is quick and easy, plus you can switch ingredients around to adapt it to any taste.

Are you in a hurry in the morning? Don’t worry! You can make this in advance and freeze it for up to 3 months. It reheats well in the oven or microwave.

You can remove the sweet potatoes to make this lower-carb, use dairy-free milk and cheese to make it dairy-free, or try the recipe as is.

5. Vegetarian Baked Spaghetti

Spaghetti is one of my favorite comfort foods, so this Vegetarian Baked Spaghetti really hits the spot. It’s packed with so much flavor and cheesy goodness that even a meat-lover would enjoy this recipe.

To make this dish, all you need to do is cook your spaghetti as you normally would, sautee all your veggies and spices together, and then combine everything with pasta sauce in a baking dish.

Top it all with cheese and bake it until the cheese is golden and bubbly!

6. Vegetarian Tater Tot Hotdish

If you’re from the Midwest and you want some vegetarian casserole ideas that remind you of home, this Vegetarian Tater Tot Hotdish is for you!

What makes this “hotdish” so tasty? The cream of mushroom soup adds a delicious savory flavor, and it’s what makes the filling so creamy and filling.

When combined with the crispy hashbrowns, it makes for a warm and comforting meal.

Monterey Jack cheese is used in this recipe, but I also like it with regular cheddar. Anything that’s nice and melty will do!

7. Vegetarian Mexican Rice Casserole

Looking for a meatless recipe, the whole family will enjoy? Try this Vegetarian Mexican Rice Casserole! It’s packed with veggies, rice, and all the classic flavors you’d expect in a Mexican dish.

I love this recipe because I can prepare parts of it ahead of time or cook it all in one go, as it really doesn’t take that much time. It’s a great way to turn leftover rice into a hearty, tasty dish.

This casserole is packed with flavor. It’s cheesy, spicy, and so filling. Make sure to top it with lots of sour cream and tortilla chips!

8. Vegan Green Bean Casserole

Vegan Green Bean Casserole is one of the best vegetarian casseroles to bring as a side to any family get-together. It’s a classic Thanksgiving dish, but you can enjoy it any time of year!

This casserole has only ten ingredients, and it takes 30 minutes to make, so it’s a great choice if you’re low on time.

You can throw it all together right before you head off to your holiday party or just cook some up to enjoy on a cold night at home.

9. Vegetable and Rice Casserole

This Vegetable and Rice Casserole is so simple, but it’s beyond delicious! You can serve this as a side dish, but it also makes a filling main course.

Rice, cream of mushroom soup, and a mix of fresh and frozen veggies all come together to create this tasty dish. A hearty amount of cheese tops it all to really bring everything together.

I like to broil the casserole for the last minute or so of cooking.

It makes the cheese crispy and brown, which is just the way I like it.

10. Vegetarian Hashbrown Casserole

Are hashbrowns one of your favorite breakfast foods? If so, this Vegetarian Hashbrown Casserole is a must-try!

This casserole isn’t just for breakfast, though. It makes a great side for potlucks, family dinners, and other occasions. It’s something the whole family will enjoy too.

Cheese is the real star of this dish, so don’t skimp on it! You can adjust things to your taste by using a cheese other than cheddar; just be sure you use a cheese that melts well.

11. Easy Vegetable Baked Pasta

This Easy Vegetable Baked Pasta is one of my favorite casserole recipes because it’s quick, easy, and super customizable.

You can use any pasta you like for this dish, so it’s a great way to use up whatever you’ve got lying around in the cupboard. You can also use whatever combination of veggies you want.

I’m a fan of spinach, peppers, and zucchini.

This recipe calls for ricotta and mozzarella, but you can leave those out to make this dish dairy-free.

Add some vegan cheese instead, or use nutritional yeast for a light cheesy flavor.

12. Spaghetti Squash Casserole

Spaghetti Squash Casserole is one of the vegetarian casseroles on this list that’s also gluten-free!

I love spaghetti squash because it’s hearty and filling but it’s also a healthier alternative to regular pasta.

Spaghetti squash is naturally low-carb and gluten-free but it’s no less delicious!

This dish uses simple, fresh ingredients and is so easy to make. If you want to make this dish vegan, all you have to do is leave out the cheese or add vegan cheese instead.

13. Vegetarian Taco Casserole

A hearty amount of veggies and beans packed this Vegetarian Taco Casserole with flavor and fill you up enough that you won’t even notice there’s no meat in this casserole.

The secret ingredient in this recipe is elbow macaroni. It gives the casserole a nice texture and absorbs all the tasty flavors from the rest of the ingredients.

Black beans are best for this recipe, but you can use pinto beans if you prefer. I always add extra jalapeños to give it a bit more kick as well.

14. Vegan Sweet Potato Casserole

Are you looking for healthy casserole recipes for vegetarians that are still just as sweet and tasty as the traditional recipes they’re based on?

If so, this Vegan Sweet Potato Casserole with Maple Pecan Topping is just for you!

This recipe has half the calories compared to regular sweet potato casserole but just as much flavor! The almond flour used makes this low-carb and gluten-free as well, but you can use another flour if you prefer.

You can also substitute the pecans for walnuts or your favorite nut.

15. Vegan Corn Pudding

Vegan Corn Pudding is a twist on a Southern classic. It’s rich and creamy just like the classic sweet corn pudding, but without all the eggs and dairy. You can also make it gluten-free by subbing the all-purpose flour for gluten-free flour.

JUST Egg is required for this recipe, so do a quick search to find a local retailer that sells it.

The rest of the ingredients are likely things you’ve got around the house or ones you can pick up at any store easily.

16. Vegan Mushroom Rice Casserole

I love this Vegan Mushroom Rice Casserole because it only takes 15 minutes to throw together and uses one pot for cooking. I can easily assemble everything and then use the hour it’s cooking to do something else!

This recipe has a lot of ingredients, but don’t let that fool you! It’s quick and easy to prepare.

I definitely recommend trying it with the breadcrumb topping, but you can leave that out and still have a delicious dish. You can mix things up by choosing your favorite herbs as well.

I like sage and rosemary.

17. Better Broccoli Casserole

Are you looking for a way to spice up the classic broccoli casserole? Here’s the dish for you! The Better Broccoli Casserole is a twist on a classic that’s even more delicious than the original.

Roasted fresh broccoli is the star of the show in his dish. Quinoa takes this casserole to the next level and adds a hearty, creamy element to the whole thing.

Quinoa is naturally gluten-free, so all you need to do to make this dish gluten-free is sub the whole wheat bread for gluten-free bread.

18. Vegetable Lasagna

Giving up meat doesn’t mean you have to give up on all your favorite dishes! This Vegetable Lasagna is easy to make and is so delicious that nobody will even notice that it’s “missing” the meat.

This recipe uses bell pepper, mushrooms, zucchini, garlic, and onions, but you can experiment and try any of your favorite veggies.

I also like it with eggplant.

Do you avoid making lasagna because of all the prep work involved? No worries! This recipe uses no-boil lasagna noodles, so this recipe is super quick to put together!

19. Cornbread Casserole

Cornbread Casserole is a great way to load up on veggies. Corn is, of course, the star ingredient, but you can use any mix of veggies you want while making this.

This recipe uses onions and bell peppers, but you can also go for some mushrooms, asparagus, peas, or zucchini. If you can saute it, you can use it in this recipe.

The green chilies, cumin, and smoked paprika give this dish a nice kick! You can experiment with other peppers as well, such as jalapeños.

I love this recipe because it is inexpensive, easy to prepare, and so tasty! The vegan cheese sauce is creamy and delicious. You definitely won’t be missing out on any of the cheesy flavors.

You can substitute the cashews in the cheese sauce for sunflower seeds or almond flour for anyone with a cashew allergy.

21. Vegetarian Black Bean Enchilada Casserole

Looking for a dish that really brings the heat? Good, because this Vegetarian Black Bean Enchilada Casserole is spicy!

The key ingredient in this dish is jalapeño sauce. If spice isn’t your thing, you can leave it out or add more than the recipe calls for if you want it to pack more punch. It’s up to you!

I like this recipe because it’s super easy to make, and it’s also customizable.

You can switch up the veggies, try out different cheeses, or forgo the cheese entirely to make this a vegan dish.

22. Easy Zucchini Casserole

This Easy Zucchini Casserole really lives up to its name! This dish is easy to prepare, and it’ll be ready for you to eat in under an hour.

This is a great healthy side option that adds a little something extra to any meal. You can also serve it over rice and eat it as the main course.

The recipe is super customizable as well. Use gluten-free breadcrumbs instead of regular ones, use vegan cheese (or omit the cheese entirely), and experiment with adding in other veggies like bell peppers.

23. Brussels Sprout Gratin

Are you looking for a more low-carb version of the classic potato gratin? Look no further! This Brussels Sprout Gratin is a great alternative that’s creamy, delicious, and vegan!

Roasted Brussels sprouts give this dish a crispy texture that is to die for. The cheese traditionally used in a gratin is substituted with vegan cashew mozzarella, though you can certainly try another vegan cheese sauce if you’d like!

The combination of creamy “cheese” sauce, crispy Brussels sprouts, and herby breadcrumbs are honestly out of this world.

24. Spinach Mushroom Pasta Bake

This Spinach Mushroom Pasta Bake may be vegan, but you certainly won’t be missing out on any creamy, “cheesy” goodness when you make this.

If you need a quick and easy dish that’s also healthy and customizable, this is definitely the recipe for you!
When I make this, I like to experiment with different types of mushrooms. Cremini is called for, but you can also try portobello, porcini, or chanterelle. I definitely recommended using the white wine in the sauce as well.
