Who says you don’t have time for eggs on weekday mornings? This Greek omelette casserole is a great meal prep idea that will ensure you’ve got a hearty and filling breakfast ready to go every morning of the week.
Clearly, I’m obsessed with omelette casseroles. Not only do I make them all of the time and share them in my Instagram story, but I’ve shared several recipes before, including my oh-so-popular spinach breakfast casserole. Although some people are worried about eating eggs on a regular basis there is actually no concern in doing so, rather, what is more important is ensuring you are buying good quality eggs. I realize the egg section at the grocery store can be incredibly overwhelming, with egg cartons littered with nutrition buzzwords, which is exactly why I wrote my guide to buying healthy eggs, so you know exactly what to look for and why.
This Greek omelette casserole is a great make-ahead breakfast idea that makes enough servings for the entire week, and stores incredibly well in the fridge, so you can’t hit snooze an extra time knowing that breakfast is ready to go.

Two questions: What size casserole dish? Can this be made the night before you bake it? Thank you
It can be made in anything from a 9×9 baking dish to a 9×12 pan. The vegetables could certainly be chopped in advance, but I would suggest whisking the eggs right before baking, once it’s cooked it will store well in the fridge for up to 5 days!
Really easy to make and very tasty.
Also very filling, but marine that’s because I ate too much of it!
Happy you liked it, thanks for sharing!
Want to double this for 12 people. What size casserole dish. Cooking times?
I have tested doubling it, but it would likely fit in a 9 x 13-inch baking dish. I’d suggest adding an extra 10 minutes of cooking time but keeping an eye on it, baking it until set in the middle.
Quick, easy, and delicious! I will be making this regularly. Thanks for the fabulous recipe!!
I’m so happy you liked it, thank you for sharing!
I’m going to try it thank you but I love the recipe♥️♥️
My pleasure, I hope you love it!
Delicious
Just for my macros what would you say a slice would be ? So excited to try this !
The recipe makes 6 servings/slices, so the macro information is based on 1/6 of the recipe. 🙂
Made it today. Easy breezy and quick! Was delicious and I followed the exact recipe. I also added a little Greek seasoning to it after baking and before eating. Also, next time I want to add diced peppers to the mix.
Love the swaps and additions and I’m so happy you liked it! Thank you for sharing. 🙂
Yum!
Easy and very yummy
This is so good! I subbed cherry tomatoes & goat cheese and it was delish. I topped my serving with plain Greek yogurt. I love that I can make this and we have a ready made breakfast for a few days!
Love that! Thank you for sharing, Emily!
