These baked ham and cheese croissants transform buttery pastries into a warm, satisfying meal perfect for breakfast or lunch. The combination of flaky croissants, savory ham, and melted cheese creates an elevated sandwich that's both simple to prepare and impressive to serve.
After making these countless times for family brunches, I've found the key lies in quality ingredients. Fresh croissants make all the difference in texture and taste.
Essential Ingredients and Selection Tips
- Croissants: Choose fresh, butter-rich ones for best results
- Ham: High-quality deli ham, sliced medium-thick
- Cheese: Swiss or cheddar work best for melting
- Dijon mustard: Adds tangy depth to each bite

Step-by-Step Instructions
Preparation
- Preheat oven to 350°F: Ensures proper baking temperature
- Slice croissants horizontally: For easy filling
- Brush insides with Dijon mustard: Adds flavor
- Layer ham and cheese: Evenly distribute for balanced bites
Assembly
- Close croissants carefully: To prevent filling from spilling
- Brush tops with melted butter: For golden browning
- Add optional seasonings: Like herbs or spices
- Place on lined baking sheet: Prevents sticking
Baking
- Heat until cheese melts: About 10 minutes
- Watch for golden brown tops: Avoid overbaking
- Cool slightly before serving: Ensures cheese sets
Through years of making these, I've discovered that layering the ham and cheese just right prevents them from sliding out while eating. Folding the ham slightly creates pockets that hold the melted cheese.
Temperature Control
350°F provides perfect melting without burning the croissants. If your oven runs hot, check at 8 minutes instead of 10.
Storage Solutions
While best served fresh, leftovers keep 2 days in airtight container. Reheat in 350°F oven 5 minutes to restore crispiness. Avoid microwave which makes them soggy.
Make-Ahead Options
Assemble up to 8 hours ahead, store covered in refrigerator. Bring to room temperature 15 minutes before baking.
Serving Suggestions
Pair with fresh fruit for breakfast or light green salad for lunch. Perfect for brunches alongside scrambled eggs.

After countless brunches and quick lunches, these croissants never fail to impress. The combination of buttery pastry, savory ham, and melted cheese creates a satisfying meal that works any time of day. Remember, quality ingredients and careful timing make all the difference.
