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.
