They’re practically effortless, loaded with goodness, and perfect for feeding a crowd. 

Even if that “crowd” is just your immediate family.

They’re ideal for meal prep, and did I mention they’re delicious?

So whether you prefer sweet or savory breakfasts, there’s a vegetarian breakfast casserole for you.

Many are healthy, and some are decidedly not. 

But every one of these 25 recipes will make your mornings tastier. 

1. Veggie-Loaded Breakfast Casserole

I know that egg salad is already a thing.

But I think this might be a better combination of the words “egg” and “salad.” At least, a more accurate one. 

This egg breakfast casserole is so loaded with veggies, it’s basically a salad.

But the salad just happened to be baked into eggs. That might sound weird, but it’s so tasty!

Every inch of it is stuffed with spinach, mushrooms, hash browns, bell peppers, and onions. Oh, and cheese. You can’t forget the cheese! 

2. Make-Ahead Breakfast Casserole

Your mornings just got easier with this make-ahead casserole.

Get it ready the night before you need it and bake it the day of. You could even bake it the night before and reheat it.

Either way, you have one less thing to worry about on busy mornings.

And you can rest easy knowing your family will be full and well-nourished.

This casserole is loaded with whatever veggies you have on hand.

So, you can customize it to satisfy even the pickiest of eaters. You can’t beat that!  

3. Veggie Breakfast Egg Casserole

Spinach, mushrooms, potatoes, broccoli, peppers, basil, onions, eggs, and cheese come together in this recipe.

That’s all you need to make this delicious egg casserole come to life! 

Of course, you’ll want to add your favorite seasonings as well. It’s easy-peasy.

4. Cracker Barrel Hash Brown Casserole

Is there anything better in this world than the combination of potatoes and cheese?

Maybe, but I think cheesy potatoes are pretty universally loved and absolutely fantastic. 

And this copycat hash brown casserole is the definition of cheesy. It also has that magical combination of creamy and crispy. 

The potatoes are crispy on top and on the edges. But everything inside is gooey and creamy.

It’s made with hash browns, tons of cheese, butter, onions, and cream of Chicken soup.

Of course, add salt and pepper to taste. I also like to add a ton of garlic.

5. Blueberry French Toast Casserole

Whoever invented French toast casseroles is a genius.

And I think they probably deserve the Nobel Prize. Because regular French toast casserole is utterly drool-worthy. 

But this blueberry cheesecake version will knock your socks clean off!

Every bite of creamy, tangy, sugary, blueberry, bread goodness is ridiculously indulgent. 

It feels sinful to eat, but it’s oh-so-good for your soul. 

6. Spinach and Mushroom Breakfast Casserole

This spinach and mushroom breakfast casserole is perfect for cold winter mornings.

It’s so hearty and cozy, and it’ll warm you up from the inside out. 

Of course, you can enjoy this year-round. And you should, because it’s really yummy.

This casserole features eggs, cottage cheese, spinach, mushrooms, garlic, onions, green onions, and cheddar cheese. It’s so flavorful. 

It’s also super soft and creamy, thanks to the cottage cheese.

It’s also very high in protein. So, you’ll definitely stay fuller for longer. 

7. Greek Omelet Casserole 

I’ve said it before on the blog and I’ll say it again, if it’s Greek, it’s good.

And this Greek-inspired egg casserole is just outstanding.

With every forkful, you’ll taste briny olives, smoky sun-dried tomatoes, salty feta, and earthy artichokes.

Spinach and eggs bump up the nutritional value even more. 

Fresh herbs and seasonings add bright, lemony, peppery goodness that’s hard to beat. Your family will love this!

8. Mediterranean Brunch Bake

This Mediterranean brunch bake is in the same family as the recipe above.

You’ll notice some similar ingredients to the previous dish, but both are delectable. 

Though, this one has even more veggies! 

9. Mexican Breakfast Casserole

When you start your day with big, bold, Tex-Mex flavors, you’re doing something right.

It’s a great way to wake up your mind and your tastebuds. 

Serve this well-spiced, veggie-and-cheese-filled casserole with fresh tomato and avocado salsa for the perfect bite. 

10. Caprese Breakfast Casserole

Caprese salad is an uncomplicated salad made of mozzarella, tomatoes, and basil.

And it’s one of my favorite salads of all time. It’s simple, yet so mouthwatering. 

I think Caprese flavors should be incorporated into as many dishes as possible.

So this breakfast casserole just makes sense. It’s delicious. 

And its flavors are pretty universally liked. This is a dish the whole family will devour.

11. Broccoli Cheese Breakfast Casserole

I know people who would typically turn up their noses at broccoli who like this dish.

Very few can resist the gooey combo of mozzarella, Swiss cheese, and cheddar. 

Sometimes, I swear that cheese has magic powers. And if you have no problems with broccoli, then you’ll love this casserole!  

12. Herb and Zucchini Kale Egg Bake

Zucchini is probably the most loved veggie in my household.

It has a fantastic flavor and is so versatile. It’s great for breakfast, lunch, and dinner. 

There are so many different ways to cook it.

And zucchini complements pretty much any other ingredient. Case in point, this scrumptious herb and zucchini kale egg bake. 

13. Cinnamon Roll Breakfast Casserole

There’s nothing quite like sinking your teeth into a sweet, soft, gooey cinnamon roll. I think most people can agree with that.

But this casserole is just as delicious.

In fact, I think it’s even better because it’s so wonderfully rich.

It’s all thanks to the cream, eggs, pecans, extra cinnamon, extra sugar, and sour cream. 

It’s like a cinnamon roll on steroids. 

14. Spinach Artichoke Egg Casserole

It’s just like the classic appetizer but for breakfast. And holy cow, it’s tasty!

It’s everything you love about the beloved dip in a breakfast bake.

It’s loaded with cheese, it’s super creamy, and it’s full of fantastic flavors.

It tastes and feels seriously indulgent, but it’s totally low-carb-friendly. 

And it will definitely keep you full all morning long, maybe even past lunch! 

15. Spring Vegetable Egg Casserole

I love these veggie egg casseroles because they change with the seasons.

You can make them a lot and never get bored. And this version is fabulous in two ways. 

First, it’s wonderfully tasty and bursting with delicious, seasonal veggies.

That includes onions, carrots, asparagus, snap peas, broccoli, mushrooms, garlic, and tomatoes! 

But you can easily make it in the winter too. In fact, it’s one of my favorite recipes with frozen peas and veggies.

16. Asparagus, Mushroom, and Swiss Egg Bake

Mushrooms plus Swiss cheese is a well-known and well-liked combination.

It’s rich and hearty and incredibly satisfying. Mushroom Swiss burgers, anyone? 

But when you add asparagus to that wonderful combo? Now, you’re in business! 

17. Cheesy Cauliflower Egg Bake

Much like broccoli, cauliflower is love-it or hate-it for most folks.

Personally, I love it, but I’ve found plenty of ways to transform it. 

And this cheesy cauliflower egg bake is just one of those delicious methods!

It’s super cheesy and it has an amazing texture. It’s soft and creamy and ooey-gooey. 

Also, if you have picky eaters, this is ideal for sneaking in extra veggies!

18. Cheesy Potato Breakfast Casserole with Cheddar and Sun-Dried Tomatoes

If you think hash brown casserole sounds good, wait until you try this!

The smoky, slightly acidic flavor of sun-dried tomatoes sends this dish over the top. 

It’s like the adventurous cousin of the hash brown casserole.

It’s still down-to-earth and comforting with just a little *something* extra about it. 

19. Vegetable Supreme Egg Bake

There’s a whole garden’s worth of veggies in this delicious bake! 

This is the perfect dish to whip up when you want to serve something hearty that you can feel good about.

It’s so good, even kids will gobble it up!

20. Ricotta and Spinach Egg Bake

This is the only dish on this list that doesn’t feature beaten eggs.

But it’s just as rustic and comforting as any dish on this list.

Every bite is absolutely divine. It’s super creamy and flavorful. But the pièce de résistance are the yolky, runny eggs. 

Serve it with crusty bread and enjoy!

21. Veggie Sweet Potato Breakfast Casserole

Everything about this veggie and sweet potato casserole sounds delicious.

Each bite is savory, with a hint of sweetness. It’s the perfect combination!

This casserole features eggs and sweet potatoes (duh). But also peppers, garlic, onions, and spinach, so it’s super nutritious!

But it also has lots of gouda cheese, making it a little bit indulgent.  

22. Strawberry Cream Cheese French Toast Casserole

To me, this succulent strawberry French toast casserole is perfectly balanced.

It tastes and feels like a dessert. But with less sugar and lighter ingredients, it’s not overly extravagant.

However, it’s still super tasty! How could it not be? It has fresh strawberries, cream cheese, sugar, lemon, and vanilla.

Plus, it’s made with challah bread, which is tender and slightly sweet. 

23. Cheesy Egg Casserole

This cheesy egg casserole is so simple but so delectable!

The combo of eggs, cottage cheese, mozzarella, butter, and Italian seasoning is truly mouthwatering. 

And the texture is so fluffy! Every bite is like a pillow of deliciousness. 

24. Breakfast Casserole with Butternut Squash and Kale

When fall comes around and butternut squash is in season, I’m in my happy place.

I try to incorporate butternut squash into every meal. Here’s my go-to, squash-filled breakfast. 

It’s bursting with warm, earthy fall flavors that evoke feelings of comfort, but it’s also pretty healthy. 

This casserole is actually a strata.

It’s like bread pudding, but not sweet. It’s made with sourdough bread, eggs, pumpkin puree, butternut squash, and kale. 

It also has plenty of delicious seasoning, Swiss cheese, and Parmesan cheese. Garnish it with sage and enjoy!

25. Apple Fritter Breakfast Casserole

Everything about this apple fritter breakfast casserole screams indulgent.

I’ll be honest, there’s nothing healthy about this casserole. But it’s worth the splurge!

You’ll devour every bite of this delectable dish. It’s basically a French toast casserole but made with day-old croissants.

Then, it’s covered with cinnamon-sugar apples, so it becomes super caramel-icious.

Once everything is baked, it’s drizzled with a sugary glaze. It’s just amazing!
