Ingredients List
For the Casserole
- 6 large croissants, torn into pieces
- 2 cups cooked ham, diced
- 2 cups shredded Swiss cheese
- 1 cup shredded cheddar cheese
- 8 large eggs
- 2 cups whole milk
- ½ cup heavy cream
- 1 teaspoon Dijon mustard
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon salt
- ¼ teaspoon black pepper

Croissants are the foundation of this recipe. Day-old croissants often work best because they absorb the custard more effectively while maintaining texture.
Swiss cheese provides a classic pairing with ham. Meanwhile, cheddar adds richness and contributes beautiful color.
The egg and dairy mixture forms a custard that binds everything together while creating the casserole’s creamy consistency.
Dijon mustard may seem like a small addition, but it enhances the savory flavors significantly and adds subtle complexity.
Step-By-Step Cooking Instructions
Preparing the Baking Dish
Grease the Dish
Preheat your oven to 350°F (175°C).
Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
Proper greasing helps ensure easy serving and cleanup later.
Arrange the Croissants
Tear the croissants into large bite-sized pieces rather than cutting them into uniform cubes.
The irregular shapes create varied textures throughout the casserole, resulting in a more interesting finished dish.
Spread half of the croissant pieces evenly across the baking dish.
Adding the Filling
Layer the Ham and Cheese
Sprinkle half of the diced ham over the croissants.
Follow with half of both cheeses.
Repeat the layers with the remaining croissants, ham, and cheese.
This layering technique ensures every serving contains an even distribution of ingredients.
Preparing the Custard
Whisk the Wet Ingredients
In a large mixing bowl, whisk together eggs, milk, cream, Dijon mustard, garlic powder, onion powder, salt, and pepper.
Continue whisking until completely smooth.
The custard should appear uniform with no visible streaks of egg remaining.
Pour Over the Layers
Slowly pour the custard mixture over the casserole.
Take your time to ensure the liquid reaches every section of the dish.
Use the back of a spoon to gently press the croissants into the custard if necessary.
Resting Before Baking
Allow Absorption
Let the casserole sit for at least 20 minutes.
If preparing ahead, cover tightly and refrigerate overnight.
During this resting period, the croissants absorb the custard, creating the rich texture that makes the dish so special.
Baking
Bake Until Golden
Place the casserole on the center rack of the oven.
Bake for 40 to 45 minutes, or until the center is set and the top is golden brown.
The casserole should puff slightly while baking.
You will notice the cheese bubbling around the edges and the aroma of buttery croissants filling the kitchen.
Check for Doneness
Insert a knife into the center.
If it emerges mostly clean and the center appears set, the casserole is ready.
If necessary, continue baking for an additional five minutes.
Resting After Baking
Cool Slightly
Allow the casserole to rest for 10 minutes before serving.
This resting period helps the custard set fully and makes slicing easier.
Additionally, it allows flavors to settle and develop.
How to Serve
Ham and Cheese Croissant Bake is best served warm from the oven.
For casual brunches, simply cut into squares and serve directly from the baking dish. The golden crust and bubbling cheese create an inviting presentation on their own.
For more elegant occasions, garnish with fresh chives or parsley before serving. The fresh herbs provide both color and flavor.
This casserole pairs beautifully with fruit platters, yogurt parfaits, breakfast pastries, and green salads.
Offering fresh fruit alongside the casserole creates a wonderful balance between rich and refreshing flavors.
Pairing Suggestions
Fresh fruit is one of the best accompaniments to this casserole. Strawberries, blueberries, melon, grapes, and citrus segments provide brightness that balances the richness.
A simple mixed greens salad with lemon vinaigrette offers freshness and contrast.
Roasted breakfast potatoes make an excellent savory side dish.
For beverages, coffee, tea, fresh orange juice, and sparkling citrus drinks all pair wonderfully.
An unexpected but delicious pairing is a tomato and cucumber salad. The crisp vegetables provide refreshing contrast while complementing the casserole’s savory flavors.
Storage, Freezing and Reheating Instructions
Store leftover casserole in an airtight container in the refrigerator for up to four days.
To reheat individual portions, microwave for 60 to 90 seconds.
For larger portions, reheat in a 325°F oven until warmed through.
The casserole can also be frozen after baking. Allow it to cool completely before wrapping tightly in plastic wrap and foil.
Freeze for up to two months.
Thaw overnight in the refrigerator before reheating.
While the croissants may soften slightly after freezing, the flavor remains excellent.
Common Mistakes to Avoid
Using Fresh Croissants
Very fresh croissants may become overly soft. Slightly stale croissants absorb custard more effectively.
Skipping the Resting Period
Allowing time for absorption is crucial for proper texture.
Overbaking
Excessive baking can dry out the custard and toughen the eggs.
Uneven Ingredient Distribution
Layer ingredients carefully to ensure balanced flavor in every serving.
Underseasoning
Egg-based casseroles benefit from proper seasoning. Taste and adjust the custard mixture before pouring.
Pro Tips

Better croissants produce better flavor and texture.
Mix Cheeses
Combining different cheeses creates greater depth and complexity.
Add Fresh Herbs
Fresh herbs brighten the rich flavors beautifully.
Assemble the Night Before
Overnight preparation enhances convenience and improves flavor development.
