Essential Ingredients
- Croissants: Select large, fresh bakery croissants for the best texture and flavor
- Eggs: High-quality eggs produce richer color and taste
- Meats: A combination of ham and bacon provides varied texture and flavor
- Cheese: Choose good melting varieties like havarti, gouda or sharp cheddar
- Honey-Mustard Spread: Creates a signature flavor that enhances all other ingredients

Preparation Method
Initial PreparationUsing a serrated knife, carefully slice croissants horizontally. Prepare honey-mustard-butter spread and apply generously to both interior surfaces.
Assembly TechniqueBegin with a cheese layer, add meats, then top with additional cheese. This layering method creates stability and prevents sogginess.
Baking ProcessBake assembled sandwiches without eggs first to achieve optimal melting and texture. Meanwhile, prepare eggs separately, cooking until just set.
Final AssemblyAdd freshly prepared eggs to the hot sandwiches. Garnish with fresh chives if desired.
This recipe emerged from attempts to recreate an expensive restaurant version at home. Through experimentation, particularly with the baking technique, these sandwiches now rival their inspiration at a fraction of the cost.
Serving Options
Fresh fruit provides an ideal accompaniment. For entertaining, consider offering a mimosa station or creating a build-your-own sandwich bar. The sandwiches pair particularly well with spicy beverages like Bloody Marys.
Variations
Create vegetarian versions with sautéed vegetables, or Mediterranean-style with roasted peppers and feta. Add avocado after baking for freshness, or incorporate hot sauce for heat. Each variation maintains the core appeal while offering new flavor profiles.

Time-Saving Tips
Prepare components in advance and assemble just before baking. Use an air fryer for reheating. When serving groups, establish an efficient assembly line system.
