21 Easy Vegetarian Casseroles: Meatless Flavor-Packed Meals🍴

21 Easy Vegetarian Casseroles: Meatless Flavor-Packed Meals🍴

If you are planning for a meatless Monday night dinner, need to accommodate a vegetarian friend, or just prefer to not cook meat, we have 21 vegetarian casseroles for you to bake in order to make your meals that much easier!

Keep in mind, that these recipes may not necessarily be vegan so there is a chance they will include dairy or eggs, however, none of these casseroles include meat.

We love casseroles for how easy and quick they are to put together!

Typically, you just put all of your ingredients into a casserole pan and bake it in the oven for a quick and easy weeknight meal.

However, these can also be used to make delicious weekend breakfasts like the Veggie Breakfast Casserole or a Cheesy Tater Tot Breakfast Casserole.

There are so many options for what you can put into your casseroles but here are some of our favorite options without any meat in them.

Try a Potato Egg Casserole or maybe even a Spinach and Mushroom Pasta Casserole.

All of these vegetarian casserole recipes are filling and hearty so you can ensure you are leaving the kitchen table feeling full and satisfied, even without adding any meat.

Not to mention how delicious these are!

With this casserole, you can easily increase the heat added in to give it some extra fire, but if you want it milder, the good news is that the sauce and spice are separated so you can adjust to your liking.

There is a nice balance of flavors in here from the black beans, corn, and colorful bell peppers added in.

To make this vegan friendly, you can leave out the cheese but otherwise, let it bake until it has melted and has made a nice cheesy topping for your enchiladas.

Pot pie is such a comforting dish but it can be a time-intensive process with preparing the pie crust.

Fortunately, this version uses biscuits rather than a pie crust and tons of flavorful vegetables with fresh herbs.

If you are missing canned biscuits in your kitchen, you can make your own with only five ingredients!

Whether you serve this as a side dish or the main course, this is probably the best vegetarian casserole for taking advantage of fresh vegetables in the summertime!

Featuring eggplants, mushrooms, tomatoes, bell peppers, and tons of fresh herbs, you can consider this your sign to visit your local farmer’s market for the freshest ingredients.

This dish is packed full of vegetables leaving you full but it avoids being too heavy.

This vegetarian casserole can win over anyone!

Cheese, broccoli, and rice taste amazing together and are quite honestly an underrated combination.

Feel free to use your favorite type of rice, add in extra veggies, or use frozen broccoli if that seems more fitting for your meal.

This is a very straightforward recipe using common ingredients, but it gives you a special casserole that is perfect for last-minute weekend brunches.

Just sautee your vegetables and pour them into a baking pan with some sliced cherry tomatoes and your egg mixture all on top of it and let it bake!

When your eggs have set and turned a beautiful golden color around the edges, you know it is ready for you to enjoy!

This is an easy vegetarian casserole, perfect for getting young children involved in preparing their own dinner!

As long as you use French, green, or brown lentils and high-quality vegetables, you can ensure that dinner will be delicious and a breeze to prepare.

Imagine an Italian version of a vegetarian Shepherd’s pie!

How delicious!

Put a twist on your traditional mac and cheese by adding in kale and quinoa to a cauliflower casserole for a veggie packed comfort dish.

Even though there isn’t macaroni in this dish, the cauliflower makes a great substitute to where you may forget you are eating vegetables.

There are also no bread crumbs on top but your quinoa will get a nice crisp texture after baking which can make a great substitute.

Of course, this is no mac and cheese substitute without a ton of sharp cheddar cheese melting throughout your casserole.

This casserole is essentially a larger version of a vegetarian baked potato.

Full of sour cream, onion, mashed potatoes, and cheese, this is a great side dish for your other homestyle comfort meals.

If you are craving a little bit of crunch or crispness with this, add on some crushed sour cream and onion potato chips to bring it all together!

Even though this casserole is designed for breakfast, it is not a bad choice for dinner, either!

The mushrooms make a great meat substitute for vegetarian casserole recipes and the onions bring out the best flavor in every bite.

The tater tots make a great base for this casserole with the sauteed vegetables topping off the crispy potatoes.

This is also great to make ahead and leftovers still taste amazing!

The butternut squash in this veggie casserole adds a nice touch of sweetness and nuttiness to an otherwise cheesy and savory dish.

If you are making this casserole around the holidays, you can leave out the cheese and instead make a brown sugar and pecan mixture for more of a holiday taste.

Some spinach or kale can go a long way with adding more greens to this recipe without taking away from the taste of the squash.

This is one of many meatless casserole recipes that double as being vegan!

Rather than using butter and dairy milk for this dish, you can use olive oil and canned coconut milk for more plant-based benefits.

There are just three simple steps for this casserole: saute some of your veggies, dump everything into a dish, and bake it!

Making tacos into veggie casserole ideas can be very easy by switching out beef for black beans.

After baking your elbow macaroni, you can just add everything to your casserole dish, stir, and bake it for about half an hour.

No one will be missing the meat from this dish since the black beans and pasta make this a satisfying dish.

Caramelized cauliflower is so versatile in cooking and using it in this casserole is just another example of one of the many ways it can be used.

There is a light tomato cream sauce filling in the space between the veggies with melted mozzarella topping everything off.

Fresh basil sprinkled on top adds a pop of freshness and a hint of sweetness.

Full of natural ingredients and easy to make from scratch, this is a great choice in meatless casserole ideas to put a hot homemade dish on the dinner table in no time.

A little bit of Dijon mustard can be optionally added to this but it is recommended since it blends well and pulls the best flavors out of all of the ingredients.

To make things easier, you can prepare this ahead of time up to baking then set it in the freezer until you are ready to bake it!

Diced sweet potatoes are the star of this dish with the black beans, salsa, and cut tortilla pieces adding a nice Mexican flair.

Chunky salsa is best for this and for your corn, try to use canned.

You do have a lot of flexibility with what you decide to add in but this recipe is already so great, that it’ll be hard to find something that it is missing!

After tasting the savory flavors of this casserole you will find yourself craving it every week.

There is a creamy filling in here full of cream cheese, milk, and some spices that really pull everything together.

Keep in mind that as this is baking in the oven, the zucchini and tomatoes will release water, but this is completely normal!

It seems like most people feel strongly about mushrooms, whether they love them or hate them.

If you are a mushroom lover, use this casserole to share the beauty of mushrooms with your friends and family.

Onions, thyme, and gruyere complement the earthiness of the fungi so well giving you a delicious vegetarian dinner or side dish in under an hour.

Remember to saute your mushrooms before you bake them so that most of the liquid has been released and evaporated so that you don’t end up with a watered down casserole.

If you are new to chilaquiles, today is your lucky day!

You are about to be introduced to a Mexican casserole that is both savory and tasty.

Fortunately, this recipe is a lighter version so you can enjoy all of the bright flavors without feeling guilty about your choice of food.

This is typically a breakfast casserole but you can serve this anytime you want a delicious meal that is guaranteed to impress.

Aside from how great this casserole tastes, one of the biggest perks is how easy it is to prepare it!

After you saute your onions and garlic, everything can go into your casserole dish and it can be baked right away.

Without meat, this is still a protein and fiber packed meal with the inclusion of lentils and brown rice!

If you want to make this a little spicier, opt for a hotter enchilada sauce or hot green chilies but you can also make adjustments to make it milder.

When it comes to cheesy pasta, there is little that needs to be done to make it better.

However, adding in some portobello mushrooms and spinach can do wonders!

Not to mention baking it so it gets a melty and cheesy crust on top!
