Best breakfast casserole
Sometimes having a breakfast that’s ready to go in the oven is a blessing. You can sit and enjoy your family and friends because you spent a few minutes making breakfast the night before. Believe me it will all be worth it.
This is one of the best breakfast casseroles we make! It’s always a huge hit and so easy to make.
Make the casserole the night before, then in the morning you just bake the casserole and make the easy creamy gravy. That’s all it takes! You may never go back to bacon an eggs or pancakes again!
Overnight Croissant Breakfast Casserole Bake with Gravy!
Not that there is anything wrong with eggs and bacon. I love a good omelette and Eggs Benedict are always on the top on the list. Oh and lets not forget a big fluffy pancake. But those breakfast foods are hard to make when your feeding a crowd.
Family breakfast
We are big fans of casseroles. Let’s face it they are always a quick and easy meal. We can usually throw them together in no time and the oven does the rest. And if your feeding a family there is nothing better than a casserole. Easy and inexpensive casseroles are the way to go.
If you can find a few different breakfast or brunch casseroles to make for your next get together your work will be so much easier. and everyone will love what you serve too! I have never seen anyone turn their nose up at a good casserole.

How to make Overnight Croissant Breakfast Casserole Bake with Gravy
You will start by making this recipe the night before you need it. Start by tearing the croissants into large bite sized pieces.
In a medium mixing bowl, whisk together the eggs, heavy whipping cream, ½ cup of the milk, mustard powder, salt, pepper, paprika, and garlic powder. Pour this mixture all over the croissants and sausage in the baking dish.
Cover the baking dish with plastic wrap and refrigerate overnight, or for 8 hours.
Remove the casserole from the refrigerator and preheat the oven to 350F
Bake the casserole at 350F for 35-45 minutes until golden brown.
While the casserole is baking, heat over medium heat the butter and 1 tablespoon of the reserved fat (from cooking the sausage) until melted. Add the flour and whisk until combined. Allow the fat and flour mixture to cook over medium heat for 1 minute.
Slowly add the remaining 2 ½ cups of milk a small amount at a time, whisking well between each addition until all of the milk is combined. Allow the gravy to simmer on low heat for 2-3 minutes, stirring often, until thickened. Add salt and pepper to taste.
Slice the casserole and serve the gravy on the side or ladled over each slice.

Great
Thank you Jean!
Do you bake the croissants before pulling apart or do you add them uncooked?
The croissants used are purchased already baked
Thanks for asking that question. I was going to put stress off raw croissant dough but lucky for me I read the comments, especially yours. Oh wow 😆
So yummy. Restaurant quality. We skipped the gravy. It was the perfect breakfast for Christmas morning. Thank you!
Thank you Rachel so glad you enjoyed! It is a favorite in our house. We like it without gravy but some like it with so we do make it for them.
I made this dish for a work potluck. It was so easy to prepare the night before. The next morning after baking the casserole, I made the gravy and poured it on top. It was a big hit. Will be making again.
Thank you Luz! So glad you liked it. We make it a lot when we have company on the weekends. Everyone always loves it.
We have made this for many Christmas mornings now and anytime in between! Super simple, and absolutely delicious! We don’t make the gravy, because it’s just fantastic even without it! Thank you for sharing!
Thank you! so happy you love it. We love it without the gravy too butt always make it for those who like to add it. 🙂
Can I make this two days in advance?
We always make it the day before. Have never tried it 2 days ahead. My only concern might be the croissants getting too mushy
How many people does this feed.
The recipe card has a serving of 12 but honestly it depends on how big of a portion people will be eating
Thanks for the recipe! Approximately how many cups of cut up croissants would you say are in the recipe? Not sure that the croissants I have are considered large and figured a measured amount might work better for me.
We never measured the croissants so I can really say. There are only 2 kinds we have ever seen. The regular size and small ones. We use your average size croissant.
