Why This Recipe is Special

There’s something nostalgic and universally comforting about warm, flaky croissants filled with gooey cheese and savory ham.

Whether you’re hosting brunch, need a fuss-free lunch, or want to impress with minimal effort, this lemon herb chicken recipe’s cheesy cousin delivers on all fronts.

Ingredients and Preparation

Croissants
Croissants are the heart of this recipe, providing a flaky, buttery base. Day-old bakery croissants work beautifully—they’re sturdy and soak up flavor without turning soggy. For a crispier bite, lightly toast them before filling.

Ham
Use thinly sliced deli ham or leftover baked ham. Its saltiness adds depth and umami, making the dish feel more savory and satisfying. Turkey or chicken slices are great substitutes.

Cheese
Cheddar, Swiss, or smoked provolone all melt beautifully. Cheddar adds sharpness, Swiss offers nutty notes, and provolone brings smoothness. Use what you love or mix them up for complexity.

Dijon Mustard
This adds tang and helps cut through the richness. Don’t skip it unless you absolutely must—though yellow mustard, honey mustard, or a thin layer of cream cheese can work in a pinch.

Butter
Brushing the tops with melted butter enhances the golden, flaky texture of the croissants. For extra flavor, add garlic powder or Italian herbs to your butter.

Optional Seasonings
Dried thyme and garlic powder give the croissants a savory punch. Use these if you like extra seasoning or are serving these as a standalone dish.

Step-by-Step Instructions

Step 1
Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper or lightly grease a 9×13-inch dish.

Step 2
Slice each croissant in half lengthwise. For extra texture, toast the halves lightly in the oven or a pan before assembling.

Step 3
Spread a thin layer of Dijon mustard on the bottom half of each croissant. This will bring a tangy kick and prevent the bread from drying out during baking.

Step 4
Layer a slice of ham and a slice of cheese on each croissant. If you’re using smaller croissants or mini ones, cut the ham and cheese to fit without overloading.

Step 5
Close the croissant halves to form sandwiches. If you’re adding any extras like tomato slices or spinach, tuck them in now.

Step 6
In a small bowl, mix softened butter with optional seasonings like garlic powder or thyme. Brush this mixture over the tops of the croissants to enhance browning and flavor.

Step 7
Place the croissants on the prepared sheet or dish. If you want extra color and crispness, whisk an egg white with a splash of water and brush it over the tops.

Step 8
Bake for 15-18 minutes, or until the tops are golden brown and the cheese is bubbling. Keep an eye on them after 12 minutes to prevent over-browning.

Step 9
Let the croissants cool for 2-3 minutes before serving. This helps the cheese settle and keeps the layers from slipping apart when bitten into.

Beginner Tips and Notes

• Cheese Overflowing? Use parchment paper—it catches melted cheese and makes cleanup a breeze.
• Ham Too Wet? Pat slices dry with a paper towel to prevent soggy croissants.
• Croissants Browning Too Fast? Loosely tent foil over the top halfway through baking.
• No Pastry Brush? Use the back of a spoon or your fingers to apply butter.
• Prepping Ahead? Assemble and refrigerate uncooked croissants overnight. Let them sit at room temp for 15 minutes before baking.

Serving Suggestions

Serve these croissants with a light arugula salad, tomato soup, or roasted veggies. For a brunch spread, include fresh fruit, yogurt parfaits, or even a mimosa bar.

Storage Tips:
Cool leftovers completely, then store in an airtight container in the fridge for up to 2 days. Reheat in a 350°F (175°C) oven for 8–10 minutes. For freezing, wrap tightly in foil and freeze for up to a month. Thaw overnight before reheating.
