Ingredients
- 6 large butter croissants, slightly stale if possible
- 8 oz cooked ham, thinly sliced or diced
- 2 cups shredded cheese (Gruyère, Swiss, or cheddar work beautifully)
- 4 large eggs
- 1 ½ cups whole milk or half-and-half
- 2 tbsp unsalted butter, melted
- 1 tbsp Dijon mustard
- ½ tsp salt
- ½ tsp black pepper
- ½ tsp garlic powder
- 1 tsp fresh thyme or parsley, chopped (optional)

Instructions
- Preheat your oven to 350°F (175°C). Lightly butter or spray a medium baking dish.
- Cut croissants into large chunks and arrange half of them evenly in the baking dish.
- Layer half of the ham over the croissants, followed by half of the shredded cheese.
- Repeat with remaining croissants, ham, and cheese.
- In a mixing bowl, whisk together eggs, milk, melted butter, Dijon mustard, salt, pepper, and garlic powder.
- Slowly pour the custard mixture evenly over the croissant layers, pressing gently so everything is moistened.
- Sprinkle fresh herbs over the top if using.
- Let rest for 10–15 minutes to allow the croissants to absorb the custard.
- Bake uncovered for 35–40 minutes, until puffed, golden, and bubbling.
- Cool slightly before slicing and serving warm.
The Secret to the Perfect Texture
The magic of this recipe lies in balance. Croissants are richer than regular bread, so they absorb custard differently. Allowing the dish to rest before baking ensures a creamy interior without becoming soggy. Using slightly day-old croissants is ideal—they soak up flavor while holding their structure.
Cheese Choices That Work Best
While ham and cheese croissants are classic, the type of cheese you choose can dramatically change the flavor profile:
- Gruyère: Nutty, rich, and traditional
- Swiss: Mild and melty
- Sharp cheddar: Bold and comforting
- Mozzarella: Extra creamy and stretchy
- Smoked cheese: Adds depth and character
You can even combine two cheeses for a more complex bite.
Variations to Try
This savory croissant casserole is endlessly adaptable:
- Breakfast version: Add sautéed onions or scrambled eggs
- Vegetarian: Replace ham with sautéed mushrooms or spinach
- Spicy twist: Add a pinch of chili flakes or pepper jack cheese
- French-inspired: Add caramelized onions and a splash of cream
- Holiday bake: Use leftover holiday ham and extra cheese
Each variation keeps the buttery croissant base while introducing new flavors.
Make-Ahead and Storage Tips
One of the biggest advantages of this recipe is how well it works in advance.
- Make ahead: Assemble fully, cover, and refrigerate up to 24 hours.
- Bake from cold: Add 5–10 extra minutes if baking straight from the fridge.
- Leftovers: Store covered in the refrigerator for up to 3 days.
- Reheat: Warm in the oven at 325°F for best texture.
This makes it perfect for busy mornings or entertaining.
Serving Suggestions

- Fresh fruit or berries
- Light green salad with vinaigrette
- Roasted potatoes or breakfast hash
- Tomato soup for a cozy dinner pairing
It’s rich and satisfying, so lighter sides balance it beautifully.
