I love a delicious recipe that can easily feed a crowd, and that’s what I’m sharing with you today! This breakfast casserole recipe is a hit with me, because not only can it feed a crowd, but if you don’t have a crowd to feed, the egg casserole refrigerated or freezes perfectly to for reheating to feed the family over the course of a couple days. Definitely a winner for quickly feeding the kids in the morning!

It’s also worth noting that many ingredients in recipe can be substituted or omitted. For example, at Christmas time, we had a bunch of leftover ham, that I used instead of sausage in the breakfast bake.

If the kids aren’t fans of spinach, it can easily be swapped for kale, or left out completely. One of my favorite subs is switching out the bell peppers in this recipe for tomatoes instead. You still get the beautiful color contrast, with a different flavor!

If you’re ready to get to cooking, let’s take a look at the recipe!
