Tips and Variations

This ham and cheese croissant casserole is really versatile and straightforward to make! Here are some suggestions for add-ins and tips for making it perfect!

Use Day-Old Croissants: Just like when making French toast, we recommend using croissants that are 1-2 days old. Stale croissants will better absorb the egg mixture and the end result will have a better texture and taste.
How to Crisp Up Fresh Croissants: If you only have fresh croissants, cut them into cubes and place them on a baking sheet. Bake at 350 degrees Fahrenheit for 8-10 minutes, watching them closely so they don’t burn. Allow the croissant pieces to cool completely before using in the recipe.
Add-ins: You can add any of your favorite breakfast staples to this casserole, cooked and chopped bacon, chopped bell peppers, sausage, or diced jalapeño for a spicy kick!
How Many Croissants: For the croissants the number you will use will vary depending on the size of the croissant. Once you’ve cut the croissants up place them into the pan you will be using to make sure it fills the pan well, they should mostly fill the pan on their own.
Cheese: If I have the extra time, I like to shred my cheese from the block so that it tastes more flavorful and melts into my casserole better.
