I genuinely believe that behind every blogger, there is a carton of eggs waiting to be demolished. And not for recipe development or cake baking or whatever the recipe du jour, but for every other meal where the last thing you want to do is be innovative in the kitchen.

I’ve yet to meet a blogger (unless they’re vegan or egg-free) who doesn’t admit to eating a ton of eggs on a daily basis. Today alone we went through 9…NINE…eggs in my house. With two people. How is that even possible?

Needless to say, I’ve tested my egg casserole skills and this vegetarian egg bake is my go-to for any breakfast gathering or potluck! It looks fancy but it actually takes 10 mins to make and has been a hit every time.

Ingredients in Vegetarian Egg Bake

The ingredient list is full of pantry staples so you can whip this up for a quick and simple breakfast casserole recipe:

  • large eggs – I like a high quality egg (you’ll notice the difference!) from a local farm or even Vital Farms.
  • onion – yellow or white onions.
  • bell pepper – I like red bell pepper but you can use yellow, orange or even green.
  • cherry tomatoes – grape or even chopped roma tomatoes will work.
  • kale -destemmed and chopped. You could also use spinach or chard.
  • cheese – you can skip this to keep it dairy free.
  • milk – I prefer using regular milk with my eggs but dairy-free works great too. 
  • salt and pepper

What to Serve With Vegetarian Egg Bake

This egg bake is a meal in one but if you’re looking for some sides or pairing suggestions, I’ve got you covered.

–> FAQs: Your Breakfast Casserole Questions Answered.

Can you prep this vegetarian egg bake in advance? Absolutely! You could prep the entire dish and store the unbaked casserole in the fridge overnight. Bake first thing when you wake up in the morning.

Can you freeze this easy egg bake? Yes! You can prep this vegetarian breakfast casserole in advance and then cover with tin foil and place in the freezer for up to 3 months. Just thaw in the fridge overnight and reheat in the oven the next morning. You could also remove a slice and head in the microwave for about 30 seconds.

Can you save leftovers? Yes! This easy veggie egg bake will last in the fridge for up to 3 days. Just cover your dish with plastic wrap or remove leftovers and place in a tupperware container. In the morning just reheat your piece in the microwave for roughly 30 seconds.

Can you use different vegetables? Absolutely! You can swap in different veggies including mushrooms, broccoli, cauliflower or whatever you have on hand. Just add to the onions and cook through before adding to eggs and baking.

What size baking dish do I need? For this vegetarian breakfast casserole you’ll want to use a 9 x 13 inch baking dish or casserole pan.

Can I swap in different cheese? Yes! I like feta in this vegetarian egg bake but you could also use different types of cheese including cheddar cheese and mozzarella.

Can I add animal protein? Yes! While this easy egg bake is vegetarian you could add another source of animal protein (besides egg) before baking. You could add cooked shredded chicken or ground sausage to eggs before baking. Bacon or other sources of ham add delicious flavor as well.

  1. On a scale of 1 to 10… how easy would this be to make in a cup cake pan (so they are little and individualized)? I’m throwing a bridal shower for my best friend and would like to limit the amount of time people spend getting food (cup cake sized casserole seems easier…).

  2. Hi! I just discovered this recipe this morning. My sister is getting married this weekend and I am hoping to make some sort of egg casserole so everyone can have some protein the morning of the wedding. Is is possible to make this casserole ahead of time and keep it in the refrigerator? Thanks!

  3. at any one time, Adam and i have a least 2 full cartons of eggs in the fridge. And then 12 hard boiled eggs as well. Needless to say, we love our eggs. This looks awesome, i just need you to come back so we can enjoy em together

  4. Oh man, I run out of eggs so quickly!! This egg bake looks SO delicious and another excuse for me to buy another carton. 😉 I’m all about easy and yummy breakfasts! My daily kitchen staples are nut butter, Greek yogurt, and hummus!

  5. im so with you on eating SO MUCH eggs..i almost always have 18 eggs on hand at any time.. #priorities. these remind me of frittata i make with whatever heck i have in the fridge

    1. yup, that’s basically why I make it haha. So easy and you can basically use whatever you have on hand!

  6. YEP totally go through 1-2 cartons of eggs a week for just me. The first thing I did this morning was hard boil a few duck eggs :’). This looks like a great recipe to add to my many egg meals!
