How to Make Flaky Ham and Cheese Croissants
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Line a large baking sheet with parchment paper.
Set it aside while you prepare the croissants.
2. Prepare the Croissants
Place the croissants on a cutting board.
Using a serrated knife, carefully slice each croissant horizontally.
Do not cut completely through the back if you prefer a hinged croissant.
Open them gently without crushing the flaky layers.
3. Add the Dijon Spread
In a small bowl, combine the Dijon mustard and mayonnaise if using.
Spread a thin layer over the inside of each croissant.
Do not use too much because excessive sauce can make the pastry soggy.
Dijon adds a mild tang that pairs especially well with ham and Swiss or Gruyère cheese.
4. Add the Ham
Fold 2 slices of ham into each croissant.
Folding rather than laying the slices flat creates more texture and allows the ham to warm evenly.
Keep most of the filling inside the croissant so the edges do not become overly dry during baking.
5. Add the Cheese
Place one slice of cheese over the ham.
If using shredded cheese, add approximately ⅓ cup to each croissant.
Swiss and Gruyère provide a classic savory flavor, while cheddar creates a richer, sharper result.
Close the croissants gently.
6. Prepare the Garlic Herb Butter
In a small bowl, combine the melted butter, garlic powder, and dried parsley or Italian seasoning.
Stir until evenly mixed.
Brush a very light layer over the tops of the croissants.
If desired, sprinkle with Parmesan.
This adds extra savory flavor and helps the tops become beautifully golden.
7. Prepare the Egg Wash
Whisk the egg and milk together in a small bowl.
Brush the tops lightly with the egg wash.
Avoid soaking the pastry.
A thin coating is enough to create a shiny, golden exterior.
8. Bake the Croissants
Arrange the filled croissants on the prepared baking sheet.
Leave a little space between each one.
Bake for approximately 10–15 minutes.
The croissants should become crisp and golden, while the cheese inside should be completely melted.
If your croissants are especially large or cold from the refrigerator, they may need another few minutes.
9. Check the Filling
Carefully open one croissant slightly or look along the edge.
The cheese should be melted and the ham should be hot.
If the croissants are browning too quickly before the filling is fully warmed, loosely cover them with foil and continue baking for a few minutes.
10. Rest and Serve
Remove the croissants from the oven.
Allow them to rest for approximately 2–3 minutes.
The cheese will be extremely hot immediately after baking.
Sprinkle with fresh parsley, Parmesan, or black pepper if desired.
Serve warm.
What to Serve With Flaky Ham and Cheese Croissants
These croissants are excellent with scrambled eggs, fried eggs, or a simple omelet for breakfast.
For brunch, serve them with fresh fruit, berries, yogurt, hash browns, or roasted breakfast potatoes.
A light green salad or tomato salad turns them into an easy lunch.
They also pair well with tomato soup, potato soup, or vegetable soup.
For a larger brunch spread, add muffins, pastries, fruit salad, coffee, and fresh juice.
Tips for the Best Flaky Ham and Cheese Croissants
Use good-quality butter croissants for the best flavor and texture.
Avoid overfilling them because too much cheese can leak heavily during baking.
Use thinly sliced ham so the croissants remain easy to eat.
Do not spread too much mustard or mayonnaise inside.
Bake just until the pastry is crisp and the cheese is melted.
Use parchment paper because a small amount of cheese may escape during baking.
Brush the tops lightly rather than soaking them with butter or egg wash.
Serve the croissants while warm for the best combination of crisp pastry and melted cheese.
Easy Recipe Variations
Ham, Egg, and Cheese Croissants
Add softly scrambled eggs before baking for a complete breakfast sandwich.
Turkey and Swiss Croissants
Replace the ham with thinly sliced turkey.
Bacon and Cheddar Croissants
Use cooked crispy bacon and sharp cheddar cheese.
Honey Mustard Ham Croissants
Replace Dijon with honey mustard for a sweeter flavor.
Ham and Gruyère Croissants
Use Gruyère cheese for a richer, slightly nutty flavor.
Spicy Ham and Cheese Croissants
Add sliced jalapeños, pepper Jack cheese, or a thin layer of spicy mustard.
Spinach Ham Croissants
Add a small amount of cooked, well-drained spinach with the ham and cheese.
Garlic Parmesan Croissants
Increase the garlic butter and Parmesan topping for stronger savory flavor.
How to Store Leftovers
Allow leftover croissants to cool completely before storing.
Place them in an airtight container or wrap them individually.
Refrigerate for up to 3 days.
For the best texture, reheat them in a 350°F (175°C) oven for approximately 6–10 minutes.
An air fryer also works very well.
Reheat at approximately 325–350°F for 3–5 minutes, checking frequently.
Microwaving is convenient but will make the pastry softer.
You can also freeze assembled baked croissants for up to approximately 1–2 months.
Wrap individually and thaw overnight in the refrigerator before reheating.
