Why You’ll Love This Ham Cheese Croissants Bake

There are many breakfast casseroles out there, but this one stands out for several reasons:

Rich and buttery texture from flaky croissants
Savory protein from ham and eggs
Melty cheese goodness in every bite
Perfect make-ahead option for busy schedules
Crowd-pleasing comfort food suitable for any occasion

Unlike traditional bread casseroles, croissants add an airy, delicate texture that absorbs the custard beautifully without becoming heavy.

Ingredients

6 large croissants, torn into chunks
2 cups cooked ham, diced or sliced
2 cups shredded cheese (cheddar, Swiss, or Gruyère work well)
5 large eggs
2 cups whole milk
½ cup heavy cream
2 tablespoons melted butter
1 teaspoon Dijon mustard
½ teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon salt
¼ teaspoon black pepper
2 tablespoons chopped fresh parsley (optional garnish)

Instructions

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray.
Tear the croissants into large bite-sized pieces and spread half evenly in the baking dish.
Sprinkle half of the ham and half of the shredded cheese over the croissants.
Add the remaining croissant pieces on top, followed by the rest of the ham and cheese.
In a large mixing bowl, whisk together eggs, milk, heavy cream, melted butter, Dijon mustard, garlic powder, onion powder, salt, and pepper until smooth.
Slowly pour the custard mixture evenly over the croissant layers, pressing gently so the bread absorbs the liquid.
Let the casserole rest for 10–15 minutes to allow the croissants to soak up the custard. (For make-ahead, cover and refrigerate overnight.)
Bake uncovered for 35–40 minutes, or until the top is golden brown and the center is set.
Remove from the oven and allow to cool for 5–10 minutes before serving.
Garnish with fresh parsley if desired and serve warm.

The Secret to the Perfect Texture

The key to a successful croissant breakfast bake is balancing moisture and structure. Croissants absorb liquid quickly, so letting the casserole rest before baking ensures even distribution without sogginess.

Using both milk and cream creates a silky custard that feels luxurious but not overly heavy.

Best Cheese Options for Maximum Flavor

While cheddar is a classic choice, experimenting with cheeses can elevate your dish:

Swiss — mild and nutty flavor that pairs beautifully with ham
Gruyère — rich, slightly sweet, and melts perfectly
Mozzarella — stretchy texture with mild taste
Pepper Jack — adds a gentle kick of spice

Combining two cheeses often produces the best results.

Make-Ahead and Storage Tips

One of the biggest advantages of this savory breakfast casserole is its convenience.

Freezing

You can freeze the baked casserole for up to 2 months. Thaw overnight in the refrigerator before reheating.

Fun Food Fact

Croissants originated in Austria, not France. The pastry evolved from the Austrian kipferl before becoming the iconic French croissant we know today. Combining croissants with savory fillings has since become popular worldwide, especially in brunch cuisine.

Frequently Asked Questions

Can I use mini croissants?

Yes! Simply use more pieces to fill the dish evenly.

Can I make this without cream?

How do I know when it’s done?

The center should be set and no longer jiggly. A knife inserted should come out mostly clean.
