Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Croissants: Use day-old croissants for the best texture; they soak up the custard without getting too soggy.
Ham: Choose diced ham or thinly sliced deli ham for convenience; both add a savory punch.
Cheese: A mix of Swiss and cheddar creates that gooey goodness; feel free to experiment with your favorites.
Eggs: Large eggs are key here; they act as the binding agent that holds everything together perfectly.
Milk: Whole milk provides creaminess; skim can work but might lack that rich flavor.
Mustard Powder: Just a pinch adds depth and enhances the flavors; don’t skip it!
Salt and Pepper: Essential seasonings to elevate all those wonderful flavors in the casserole.

Let’s Make it Together
Prepare the Oven and Dish: Preheat your oven to 350°F (175°C) while you prepare your baking dish. Grease a 9×13 inch baking dish with butter or non-stick spray.
Assemble Ingredients: Chop your croissants into bite-sized pieces and place them in a large bowl. Toss in diced ham and shredded cheese until well mixed.
Create the Egg Mixture: In another bowl, whisk together eggs, milk, mustard powder, salt, and pepper until fully combined. This flavorful mix will coat all those delightful ingredients.
Combine Everything Gently: Pour the egg mixture over the croissant mixture and gently fold everything together until each piece is coated. Let it sit for about 10 minutes for maximum absorption.
Bake to Perfection: Transfer everything into your prepared baking dish and spread it out evenly. Bake for 30-35 minutes or until golden brown on top and set in the middle.
Cool Before Serving: Once baked, let it cool for about 5 minutes before slicing into squares. This will help everything hold together nicely when serving!
