Ham and cheese croissants are the ultimate savory pastry—buttery, flaky croissants filled with tender ham and melted Gruyère cheese. They’re perfect for breakfast, brunch, or a light lunch. While you can use store-bought croissants, making them at home with quality croissants takes them to another level.
This recipe shows you how to assemble and bake perfect ham and cheese croissants, whether you’re using homemade croissants or high-quality bakery ones. The combination of rich, buttery pastry, salty ham, and nutty, melted cheese is simply irresistible.

Instructions
Preheat the Oven
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Prepare the Croissants
Slice each croissant horizontally, leaving one side attached if desired (like a book) or cutting all the way through for easier filling.
Spread Mustard (Optional)
If using, spread a thin layer of Dijon mustard on the bottom half of each croissant.
Layer the Fillings
Layer the ham and cheese slices inside each croissant. Be generous but don’t overstuff—you want the croissant to close easily.

Brush with Butter
Close the croissants and place them on the prepared baking sheet. Brush the tops with melted butter for a golden, glossy finish.
Bake
Bake for 10-15 minutes, until the croissants are warm, the cheese is melted, and the tops are golden and crispy.
Serve
Serve warm with Dijon mustard, cornichons, and a side salad.
Pro-Tips for Ham and Cheese Croissant Perfection
- Use All-Butter Croissants: The flavor and flakiness of all-butter croissants make a huge difference.
- Don’t Overstuff: Too much filling can make the croissant difficult to eat and cause it to burst open.
- Grate Your Own Cheese: If using shredded cheese, grate it yourself for better melt.
- Warm Them Up: These are best served warm, straight from the oven.
- Add a Little Sweetness: For a twist, add a thin layer of honey or fig jam along with the ham and cheese.
- Make Ahead: You can assemble the croissants ahead of time and refrigerate. Bake just before serving, adding a few minutes to the baking time.
- Variations: Try adding a fried egg for a breakfast version, or use prosciutto and mozzarella for an Italian twist.
- Perfect Pairing: Serve with a simple green salad dressed with vinaigrette to cut through the richness.
These Ham and Cheese Croissants are flaky, buttery, and absolutely perfect.
