Ingredients You’ll Need
- 6 large croissants: These will serve as the base of the casserole, providing a flaky and buttery texture. The croissants soak up the egg mixture beautifully.
- 1 cup diced ham: Adding diced ham gives a savory punch of flavor, making this casserole hearty and satisfying.
- 1 cup shredded Swiss cheese: The melting quality of Swiss cheese offers creaminess and a mild flavor that complements the ham.
- 6 large eggs: These are the binder of the dish, giving it structure and richness.
- 2 cups milk: Milk adds moisture; a combination of half-and-half or cream can be used for a richer taste.
- 1 teaspoon Dijon mustard: This little addition offers a hint of tanginess that elevates the flavor profile.
- ½ teaspoon salt: Essential for balancing the flavors.
- ½ teaspoon black pepper: Provides a small kick to the dish.
How to Make
- Begin by preheating your oven to 350°F (175°C). While the oven is heating, prepare a 9×13 inch baking dish by lightly greasing it with cooking spray or butter to prevent sticking.
- Next, chop the croissants into bite-sized pieces and place them evenly in the bottom of the prepared baking dish. Make sure to cover the base as evenly as possible for a consistent texture.
- In a separate bowl, whisk together the eggs, milk, Dijon mustard, salt, and pepper until well combined. This mixture will soak into the croissants, creating a custardy texture.
- Once the egg mixture is ready, pour it evenly over the croissant pieces. Press down gently with a spatula to ensure that the croissants absorb the mixture thoroughly.
- Sprinkle the diced ham and shredded Swiss cheese evenly on top. The combination of flavorful ham and creamy cheese means every bite is delicious.
- Bake in the preheated oven for about 45 minutes, or until the casserole is puffed and golden brown on top. A toothpick inserted in the center should come out clean, indicating that it’s fully cooked.
Variations & Substitutions
Vegetarian Option: For a meat-free option, consider replacing the ham with sautéed vegetables like spinach, bell peppers, and mushrooms. You can add in some feta or goat cheese for extra flavor.
Cheddar and Bacon Twist: If you’re a fan of stronger cheese and smoky flavors, swap the Swiss cheese for sharp cheddar and the ham for crispy bacon. This will give your casserole a distinct twist and is especially delightful for a hearty morning meal.
Herbed Southwest Style: Add a southwestern flair by incorporating ingredients like chorizo or black beans, and season the mixture with cumin and chili powder. Top with pepper jack cheese for an extra kick.
Common Mistakes to Avoid
When preparing this breakfast casserole, be mindful of a few common pitfalls. First, make sure the croissants are not too stale; otherwise, they won’t absorb the egg mixture adequately, leading to a dry casserole. Second, resist the urge to skip the letting time. Allowing the dish to sit for a few minutes before baking helps ensure even cooking. Finally, check for doneness using a toothpick before serving; this avoids the disappointment of an undercooked center.
Storage, Freezing & Reheating Tips
To store any leftovers, cover the casserole tightly with plastic wrap or aluminum foil and keep it in the refrigerator for up to 3 days. If you’d like to freeze it, consider slicing portions first. Wrap each piece in plastic wrap and then place them in a freezer-safe container. This method allows for easier reheating later on. To reheat, simply place a slice in the microwave for a few minutes or warm up individual portions in the oven until heated through. Ensure leftovers are heated to a safe internal temperature of 165°F (74°C) for food safety.
Frequently Asked Questions
Can I prepare this casserole the night before?
Absolutely! This is one of the joys of this breakfast casserole. You can assemble all the ingredients the night before, cover it with plastic wrap, and refrigerate. In the morning, just pop it in the oven and enjoy a delicious breakfast without the hassle.
What kind of milk should I use?
You can use any type of milk, from whole to skim, or even non-dairy alternatives like almond or oat milk. However, using whole milk creates a creamier texture. If you want an even richer dish, consider using half-and-half.

How do I know when my casserole is done?
Your casserole is done when the top is golden brown and firm to the touch, and a toothpick inserted in the center comes out clean. If the edges of the casserole darken too much while cooking, you can cover it lightly with foil to prevent burning.
