I’m ALL about egg bakes. Seriously….is there anything better? Not only are they easy to prepare and such a delicious way to wake up….but the possibilities for them are endless. And this Ham & Cheese Croissant Egg Bake? Well, it just might be my new favorite!

For one, you can’t go wrong with ham & Swiss. It’s a classic combo for good reason. And then there are the croissants. Yep…you heard me right. Ham + Swiss + eggs + CROISSANTS!!! It’s pretty much heaven in a 9×13 inch pan.

Perfect for Easter brunch, Christmas morning, or anytime you want to treat yourself! And, not that you needed any more reasons to love this recipe, but it reheats beautifully. So just in case you happen to have any leftovers, you’re good to go! It really doesn’t get any better than that.

what you’ll need for this croissant breakfast casserole recipe

Croissants – I used 4 large store bought croissants for this recipe, which can be found in the bakery section of the grocery store. Since you’re using them in a casserole, I wouldn’t worry as much about finding high quality croissants.
Eggs – I used 10 large eggs.
Milk – I added 1 1/4 cups milk. Feel free to substitute heavy cream or half and half for the milk. Doing so will produce a richer result. Just keep in mind that there’s already a great deal of richness from the croissants, eggs, and Swiss cheese.
Sour cream – I added 1 cup sour cream for richness.
Shredded cheese – I used 1 cup shredded Swiss cheese
Ham – Feel free to use any kind of ham you have in your fridge, from deli ham to ham steak to leftover Easter ham. As long as it’s chopped into bite sized pieces, it will work well in this recipe.
Salt & pepper

how to make croissant egg bake

Cut the croissants. Cut the croissants into 2 inch cubes and spread them in a 9 x 13-inch baking dish.

Whisk the egg mixture. In a medium mixing bowl, combine eggs, milk, sour cream, salt & pepper. Whisk well.

Combine & refrigerate . Stir in shredded cheese and ham. Pour egg mixture over the croissants; cover and refrigerate overnight.

Bake. Remove from fridge and bake at 350° for 55-60 minutes. Enjoy!

storing & reheating

Leftovers can be stored, covered, in the refrigerator for 3-4 days. You can store them right in the pan (covered with aluminum foil) or in an airtight food storage container. The best way to reheat this recipe is in the oven or toaster oven, both of which allow the croissants to crisp up a bit. However, this dish will also reheat well in the microwave.
