Ingredients You’ll Need
The beauty of Ham and Cheese Croissant Breakfast Casserole Delight lies in its approachable, everyday ingredients that come together for a truly unforgettable bake. Each element plays a starring role, lending its taste and texture to the dish and ensuring every bite is bursting with flavor and comfort.
- Croissants: Buttery and flaky croissants soak up the custard and provide a pillowy, melt-in-your-mouth texture.
- Diced ham: Adds savory depth and a lovely chewier bite that contrasts beautifully with the softness of the croissants.
- Swiss cheese: The distinctive nutty flavor of Swiss cheese melts perfectly for a gooey, creamy finish.
- Parmesan cheese: Sprinkled on top, Parmesan grants a sharp, golden crust and extra flavor dimension.
- Eggs: Six large eggs create the rich custard base that holds everything together.
- Milk: Milk ensures the custard is ultra-creamy and bakes up with the perfect consistency.
- Dried thyme: A teaspoon adds herbal brightness that livens up the casserole.
- Garlic powder: For a subtle savory backbone that boosts every bite.
- Salt and pepper: Season to taste, highlighting all those cozy, cheesy flavors.
- Fresh chives: Sprinkled on before serving, chives add a fresh, oniony pop of color and flavor.
How to Make Ham and Cheese Croissant Breakfast Casserole Delight
Step 1: Prep Your Pan
Start by preheating your oven to 350°F (175°C) and giving your 9×13 inch baking dish a generous coating of butter or cooking spray. This ensures those delicious croissant corners get perfectly golden and releases easily after baking.
Step 2: Layer the Croissants
Quarter your croissants and scatter them evenly in the prepared baking dish. Their shapes and layers create lovely nooks and crannies that will soak up the savory custard later on and form the hearty foundation of your Ham and Cheese Croissant Breakfast Casserole Delight.
Step 3: Add Ham and Cheese
Sprinkle diced ham and shredded Swiss cheese evenly over the croissants. Gently shake the pan to help all those delicious morsels nestle between the croissant pieces, ensuring every serving gets a bit of everything.
Step 4: Whisk the Custard
In a medium bowl, whisk together the eggs, milk, dried thyme, garlic powder, salt, and pepper until smoothly combined. This custard mixture is the magic glue that transforms the casserole into a creamy, cohesive delight.
Step 5: Assemble the Casserole
Pour the custard evenly over your croissant, ham, and cheese layers. Use a spatula to gently press down, helping those flaky croissants soak up every last drop of flavor. Then, sprinkle the grated Parmesan cheese over the top for a beautifully golden, savory finish.
Step 6: Bake to Golden Perfection
Cover the pan loosely with aluminum foil and bake for 30 minutes. Then, remove the foil and let it bake for another 15 to 20 minutes. The top should be golden brown and puffy, and the center set but still a bit tender for that perfect texture.
Step 7: Garnish and Serve
Let the casserole cool for about five minutes after baking. This little pause helps everything set. Right before serving, sprinkle with fresh chopped chives for a bright color pop and fresh flavor boost. Slice into generous portions and enjoy the delight!
How to Serve Ham and Cheese Croissant Breakfast Casserole Delight

Garnishes
Don’t underestimate the finishing touch! A scatter of fresh chopped chives over the top adds just the right amount of color and a gentle, oniony zing that beautifully complements the rich flavors in your Ham and Cheese Croissant Breakfast Casserole Delight. For something extra special, a light dusting of freshly cracked black pepper or an extra sprinkle of Parmesan right as it comes out of the oven makes it look irresistible.
Side Dishes
This casserole loves good company. Balance the richness with a platter of fresh sliced fruit (like berries, melon, or citrus), or toss together a crisp green salad with a light vinaigrette. If you want to go all-in on brunch, serve with roasted potatoes, asparagus, or even a sweet fruit compote on the side.
Creative Ways to Present
Bring a sense of occasion to your Ham and Cheese Croissant Breakfast Casserole Delight by plating each portion in wide, shallow bowls and garnishing with a small bouquet of herbs or edible flowers. For more casual gatherings, slice the casserole into squares, pile on a serving platter, and let friends and family help themselves. Individual ramekin portions are adorable for special brunches or holiday mornings, too.
Make Ahead and Storage
Storing Leftovers
Wrap any leftovers tightly in plastic wrap or foil, or transfer slices into an airtight container. Stored in the refrigerator, your casserole will stay fresh and delicious for up to three days, making it a fantastic make-ahead option for busy mornings or next-day lunches.
Freezing
If you’d like to freeze: once completely cooled, wrap the casserole tightly in a double layer of plastic and then foil, or place portions in airtight freezer containers. Your Ham and Cheese Croissant Breakfast Casserole Delight will keep well in the freezer for up to two months. Thaw overnight in the refrigerator before reheating for best results.
Reheating
Reheat single portions in the microwave for about 1-2 minutes until warmed through, or bake larger portions in a 350°F oven covered with foil. Remove the cover for the last few minutes to keep that glorious golden crust intact.
FAQs
Can I use a different type of cheese?
Absolutely! Feel free to swap out Swiss for cheddar, Gruyère, or even mozzarella. Just choose a good melting cheese for that gooey, luscious texture Ham and Cheese Croissant Breakfast Casserole Delight is famous for.
Can I make this dish vegetarian?
Yes! Substitute the ham with sautéed mushrooms or a medley of roasted vegetables for a meat-free (but equally delicious) variation on this brunch classic.
Should the croissants be fresh or stale?
Slightly day-old croissants actually work best here, since they soak up the custard more efficiently and hold their shape beautifully. If using extra-fresh croissants, just make sure to press down well so the custard gets evenly absorbed.
How far in advance can I assemble the casserole?
You can assemble the casserole the night before, cover tightly, and refrigerate it overnight. In the morning, just pop it in the oven and bake as directed for a fuss-free, crowd-pleasing breakfast.
Can I add vegetables or herbs to the casserole?
Go for it! Spinach, sun-dried tomatoes, sautéed onions, or bell peppers all make fantastic additions to the Ham and Cheese Croissant Breakfast Casserole Delight. Experiment with your favorite fresh herbs to make it your own.
