- 1 cup shredded Swiss cheese: Melts into creamy goodness with a mild nutty flavor.
- ½ cup grated Parmesan cheese: Sprinkled on top for a golden, tangy crust.
- 6 large eggs: The foundation of the custard, binding everything together.
- 2 cups milk: Creates a luscious custard that infuses the croissants with moisture.
- 1 teaspoon dried thyme: Offers a subtle earthy herbiness that lifts the flavors.
- 1 teaspoon garlic powder: Adds a gentle savory kick without overpowering the dish.
- Salt and pepper to taste: Essential for balancing and enhancing all the flavors.
- Fresh chives, chopped (for garnish): Adds a lovely pop of color and a mild oniony freshness.
How to Make Ham and Cheese Croissant Breakfast Casserole Delight
Step 1: Preparing the Baking Dish
Start by preheating your oven to 350°F (175°C) and greasing a 9×13 inch baking dish. This step is crucial because it ensures your casserole won’t stick and will come out cleanly after baking, ready for those beautiful slices you’ll serve.
Step 2: Layering Croissants, Ham, and Cheese
Evenly spread the quartered buttery croissants across the bottom of your dish, creating the foundation that will soak up all the custard. Scatter the diced ham evenly over the croissants, then sprinkle shredded Swiss cheese on top to melt into the contours of the croissants as the casserole bakes.
Step 3: Making the Egg Custard
In a medium bowl, whisk together the eggs, milk, dried thyme, garlic powder, salt, and pepper. This savory custard mixture is what will bind the casserole’s layers, infuse rich flavor, and create a creamy texture that sets perfectly in the oven.
Step 4: Pouring and Pressing
Pour the custard evenly over the croissant, ham, and cheese layers, taking care to ensure every piece is soaked. Gently press down with a spatula to help the croissants absorb the mixture, giving you that irresistible custardy softness once baked.
Step 5: Adding Parmesan and Baking
Sprinkle the grated Parmesan cheese on top to create a savory crust. Cover the dish with aluminum foil and bake for 30 minutes to let everything meld together. Then remove the foil and bake another 15 to 20 minutes until golden brown and set in the center, signaling your Ham and Cheese Croissant Breakfast Casserole Delight is ready.
Step 6: Cooling and Garnishing
Allow the casserole to cool for about 5 minutes before slicing. Sprinkle fresh chopped chives on top for a vibrant finishing touch that adds freshness and color, inviting everyone to dig in.

Garnishes
Freshly chopped chives are the perfect garnish for this casserole, providing a pop of green and a mild onion flavor that complements the richness. You can also consider a light drizzle of hot sauce or a dollop of sour cream for those who like an extra layer of flavor.
Side Dishes
This casserole pairs beautifully with seasonal fresh fruit, which adds natural sweetness and a refreshing contrast. A crisp green salad or simple roasted asparagus can also balance the richness if you’re serving it for brunch or a light lunch.
Creative Ways to Present
Slicing the Ham and Cheese Croissant Breakfast Casserole Delight into neat squares and plating each portion with a small side of fresh berries or a colorful fruit salad makes for a stunning presentation. For entertaining, arrange mini waffle cones filled with mixed greens alongside the casserole for an unexpected and charming touch.
Make Ahead and Storage
Storing Leftovers
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. The custard and croissants hold up well, and flavors deepen overnight, making it even tastier the next day.
Freezing
You can freeze the casserole either baked or unbaked. Wrap tightly with foil and plastic wrap for up to 2 months. To bake from frozen, thaw overnight in the fridge and bake as directed, adding a bit of extra time as needed.
Reheating
Reheat leftovers in the oven at 325°F (160°C) for about 15-20 minutes until warmed through and the crust regains its crispness. Microwaving works too but may soften the croissant edges.
FAQs
Can I use other types of cheese?
Absolutely! While Swiss and Parmesan are delicious here, feel free to experiment with Cheddar, Gruyère, or even a smoky Gouda to tailor the flavor to your preferences.
What if I don’t have croissants? Can I use bread instead?
Yes, you can substitute with rustic bread or brioche cubes, but croissants provide that special buttery, flaky texture that makes this casserole stand out.
Can I add vegetables to this casserole?
Definitely. Diced bell peppers, spinach, or mushrooms are excellent additions that make the casserole heartier and add a fresh twist.
Is this recipe suitable for meal prep?
Yes, it’s a fantastic make-ahead dish. You can prepare everything the night before, refrigerate, and bake fresh in the morning for an effortless breakfast surprise.
How can I make this recipe vegetarian?
Simply omit the ham and consider adding more cheese or savory vegetables like roasted tomatoes or zucchini for a satisfying vegetarian version.
