My husband Tommy claimed this healthy breakfast casserole to be the BEST breakfast casserole recipe he’s ever tasted. In fact, he loved it so much he reheated the leftovers the next morning! What he loved most was the texture of the eggs. They are fluffy and light – almost custard-like thanks to adding just a touch of heavy cream. I’m not a fan of spongy eggs and love the texture of this crustless quiche, so I took inspiration from that recipe.

I’m excited to partner with Pyrex to share this breakfast casserole! Whether it’s celebrating the holidays with friends, family or even coworkers, holiday parties can be hectic! Pyrex Deep helps you get any holiday party off on the right foot with more food and larger dishes! This breakfast casserole is made with two dozen eggs so it feeds a large crowd. Plus, you can make it the night before, so it’s perfect for holidays or if you have a large group of people spending the night and you don’t have a lot of time to prepare in the morning. The great thing about this recipe is how adaptable it is! And because this dish is SO deep, you can pack tons of more ingredients in it! Here’s some ideas to make an epic breakfast casserole.

Add more veggies! Bell peppers, zucchini, mushrooms would all be great options. Add some meat. Try this with chicken sausage, diced ham or chopped turkey bacon. Try different cheese options. Swap out the Feta cheese for ricotta, Parmesan, Swiss cheese or cheddar. Add some herbs. Chopped dill, parsley or chives would make a great addition.

How to Make Breakfast Casserole:

The main ingredients for this egg casserole are really simple and include eggs, spinach, tomatoes, shallots, and Feta cheese. We add a little heavy cream and milk to the egg mixture to make it creamy, light and fluffy. To make the casserole, saute the shallots in a little oil to soften. Then add the spinach and cook for about two minutes until it wilts. Combine with the remaining ingredients and pour it into a Pyrex Deep 9×13-inch baking dish. Bake until the edges are set and browned and the center is a little jiggly in the center. It will continue to cook and set up as it cools.

Pyrex Deep

New Pyrex Deep baking dishes are the deepest glass baking dishes sold in the US and hold up to 50% more than your current glass bakeware. Everyone has had that moment when they’re cooking. The casserole is in the oven and you get distracted – next thing you know, the food as boiled over and is bubbling on the floor of your oven. Then comes the smell and smoking. Great news, the deeper size of Pyrex Deep lets you bake your favorite holiday recipe without it spilling over. The dishes come with lids for easy storage of leftovers or transportation to parties and potlucks. You can find it at PyrexHome.com and Walmart.

Storing Leftovers:

Leftover egg casserole can be refrigerated for up to 4-5 days. Leftovers are delicious reheated in the microwave.
