How to Make Ham and Cheese Croissant Breakfast Casserole
Ingredients for this Breakfast Casserole
- ham – you’ll use chopped cooked ham. This is great for using leftover baked ham! You can also use your favorite deli ham.
- cheeses – you’ll use Parmesan cheese and cheddar cheese in this casserole. If you prefer other cheese combinations, you can use those as well.
- onions – In the recipe, I list to use sliced green onions here. It adds color and flavor. You can substitute with diced onion if needed. If you don’t care for onions, you can leave them out.
- croissants – you’ll cube large croissants to use in the recipe. I use store-bought from the grocery store or a local bakery.
- milk and heavy cream – I use whole milk and heavy cream in this casserole. It adds richness and a creamy texture to the final dish.
- eggs – you’ll use large eggs
Step-by-Step Instructions
It is so easy to toss all the ingredients together that you’ll have it whipped up and prepped for the refrigerator in no time.
Prep. Spray a 9×13 baking dish with nonstick cooking spray or you can lightly coat with butter.
Mix and chill. Combine the ham, Parmesan cheese, onions, and croissants in a medium mixing bowl. Arrange in prepared baking dish. Whisk together milk, cream, and eggs and pour over the croissant mixture. Cover and chill overnight.
Chilling the casserole lets the croissants absorb as much liquid as possible for a creamy and delicious breakfast casserole.
Bake and serve. Preheat oven to 350º F. Uncover the casserole and sprinkle with the Cheddar cheese. Bake until golden brown and cooked throughout, about 45 minutes. Remove from the oven and let stand for 5 minutes before serving.

Is there a substitution for ham for a vegetarian version? I guess you can omit the ham but what would be a nice substitute to keep it elegant? Thank you.
Yes you can use vegebacon.
could you freeze after assembling?
This casserole is seriously tasty! I made as written, except I mixed all of the cheese in with the ingredients instead of sprinkling the cheddar on top. The only note is that this took way longer than 45 minutes to set. At the 45 min mark the casserole was still mostly liquid, so I upped the temp to 375F and added an extra 30 minutes of cook time.
I’ve made this casserole multiple times over the last month using leftover Christmas ham in the freezer. It’s effortless to make and SO very tasty. I cut the recipe by a third (four croissants instead of six) for my hubby & me.
This is an excellent way to use leftover ham, isn’t it, Molly? Love that you can adjust this recipe to make it for just two.
