Why I Love This Ham and Cheese Croissant Casserole

I am not a huge fan of breakfast, but I do love a good breakfast casserole. I like when the eggs combine with the cheese and the meat and the bread or potatoes. Maybe that’s why I have a thing for breakfast sandwiches.

I also have a thing for croissants, and could eat them pretty much any time. Well, you know how a lot of yummy breakfast casseroles call for bread? It’s used as a binder to hold everything together. The croissants do that in this casserole and holy yum do they take it to a whole ‘nother level. Savory ham, tender, flaky croissants and creamy cheese. It doesn’t get much better!

How to Make a Croissant Breakfast Casserole

  • Prep. Grease a square baking dish.
  • Layer. Cut up a bunch of croissants into bite sized pieces and layer half of them in the dish. Add chopped ham and shredded cheddar and more croissant pieces.
  • Mix custard. Whisk together eggs, milk, honey, mustard, salt, pepper and nutmeg. Pour over the croissants, making sure each piece is moistened with the egg mixture.
  • Cover and refrigerate. Cover the pan with foil and refrigerate overnight.
  • Bake. Preheat the oven to 325°F, uncover the casserole and bake (covered) for 35 minutes, then uncover and bake for an additional 25 minutes.

  1. What would happen if I forgot to make this overnight, and didn’t let it sit for 8 hours? Would it be messed up?

  2. Oh wow! this is wonderful. I was in the mood for something like this. The saltiness of the ham with the croissant and eggs. the touch of mustard was inspired! I’m making a list of stuff for the holidays and this is a must. I think I would like to try freezing a batch just to see how it changes when reheated! I’m thinking sautee mushrooms might be good in this also! Bet I could use croissants left over from dinner as well. Thanks so much for this.

    1. Gosh! This was delicious!! We had overnight guests and needed to rush out the door to an NFL game this morning. I prepped everything early yesterday afternoon and popped it in the oven after coffee. Served it with a fruit salad. Rave reviews from the friends and my husband now wants to propose to you. He is a sucker for ham and cheese, but the Dijon sent him over the moon!
      Thank you, Maria. I will make this again and again 🙂

  3. Can this be made ahead of time then freeze it? If so what would your recommendation be for reheating?

    1. If you want to bake this ahead of time and then freeze, let the casserole cool completely, then cover it tightly with plastic wrap and/or foil. Pop it in the freezer for up to 4 months. To reheat, thaw overnight in the fridge then bake at the same temperature as called for in the recipe until it’s hot in the middle. You might want to leave it covered with foil so as not to brown the top too much.
