Why You'll Love This Recipe
About the Ingredients
6 large croissants
Day-old croissants work best as they hold up to filling. Substitute with brioche buns if needed.
8 large eggs
Farm-fresh eggs add richer flavor. Use 6 if you prefer less egg per sandwich.
1/4 cup (60ml) whole milk
Adds creaminess to scrambled eggs. Use half-and-half for extra richness.
1/2 teaspoon salt
Fine sea salt dissolves easily. Adjust to taste.
1/4 teaspoon black pepper
Freshly ground gives the best flavor.
2 tablespoons (28g) unsalted butter
For cooking eggs and buttering croissants. Use salted butter and reduce salt if preferred.
12 thin slices (about 200g) ham
Black forest ham or smoked ham adds smoky depth. Swap for turkey or prosciutto.
6 slices (about 150g) Swiss cheese
Gruyère or cheddar also melt beautifully. Choose your favorite.
Optional: Dijon mustard, for spreading
A thin layer adds tangy kick. Omit for kids.
Tips & Tricks
Use day-old croissants
They are sturdier and hold the filling better without getting soggy.
Don't overcook the eggs
Remove them from heat slightly underdone as they'll finish cooking from residual heat.
Toast the croissants
This prevents sogginess and adds a delicious crunch.
Pro Tips
Step-by-Step Instructions
1. Preheat Oven
Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
2. Whisk Eggs
In a medium bowl, whisk eggs, milk, salt, and pepper until well combined and slightly frothy.
3. Scramble Eggs
Melt 1 tablespoon butter in a nonstick skillet over medium heat (350°F/175°C). Pour in egg mixture. Cook, stirring gently with a spatula, until softly set but still moist, about 3-4 minutes. Remove from heat immediately.
4. Slice Croissants
Slice each croissant horizontally, leaving one side attached like a book. Spread a thin layer of Dijon mustard on the bottom half if using.
5. Butter and Toast
Melt remaining 1 tablespoon butter and brush onto the cut sides of croissants. Place on baking sheet and toast in oven for 5 minutes, until lightly golden and crisp.
6. Assemble Sandwiches
Remove croissants from oven. On each bottom half, layer 2 slices of ham, a portion of scrambled eggs, and 1 slice of cheese.
7. Melt Cheese
Return assembled sandwiches to oven and bake for 3-4 minutes, until cheese is melted and edges are bubbling. The croissants should be golden brown.
8. Serve Warm
Close the croissants gently and serve immediately. Enjoy the buttery, flaky goodness!
