Savory Croissant Breakfast Casserole

This savory croissant breakfast casserole is a great option when you want to impress guests. It can even be prepared the night before and refrigerated overnight to make your morning less chaotic. Don’t you love recipes you can prep the night before so all you have to do is put it in the oven? I love to use bacon and leftover deli meat but ground breakfast sausage would also be a tasty option.

I love this recipe because it’s a great way to use up extra croissants, eggs, or sandwich meat if you have too much hand. I know that I usually always have a ton of eggs on hand because my mom has a few laying hens at her house. There was one time when she sent me home with six cartoons of eggs, that’s right, six cartons, not just six eggs! I gave some to friends and neighbors and also made this lovely breakfast casserole.

This is also a wonderful breakfast casserole to make for busy holiday mornings since you can prep it the night before. I’ve also made this for baby showers and potlucks and gotten rave reviews on it!
