This buttery, cheesy croissant breakfast sandwich combines the flaky goodness of fresh croissants with savory fillings for an elevated morning meal that feels special yet comes together quickly. Perfect for weekend brunches or meal prep, these sandwiches feature a secret honey-dijon butter that adds a sweet-tangy kick to every bite.
I created these sandwiches for a last-minute family gathering when I needed something impressive without spending hours in the kitchen. The combination of that special honey-dijon spread with the melty cheese had everyone asking for the recipe before they even finished eating.
Ingredients
- Croissants: Large bakery-style ones provide the best texture and buttery flavor
- Dijon mustard: Adds tang and depth to the special spread
- Honey: Balances the mustard with just the right sweetness
- Butter: Creates richness in both the spread and the eggs
- Cheese: Choose something that melts well like Gouda, Swiss, or cheddar
- Deli ham: Opt for high-quality slices with good moisture content
- Bacon: Adds a smoky crunch that complements the soft croissant
- Eggs: The protein-packed filling that makes this a complete meal
- Milk: Creates fluffier scrambled eggs
- Fresh chives: Brightens the finished sandwich with color and mild onion flavor
Step-by-Step Instructions
- Prepare the special spread:
- Combine dijon mustard, butter, and honey in a microwave-safe bowl. Heat for 20 seconds until the butter melts, then stir until completely smooth. This sweet-tangy spread is what transforms these from ordinary to extraordinary sandwiches.
- Prepare the croissants:
- Slice croissants horizontally using a serrated knife, making sure to keep the top and bottom connected at the back if possible. Brush the cut sides generously with the prepared honey-dijon butter, allowing it to soak slightly into the croissant.
- Layer the fillings:
- Place a slice of cheese on each croissant bottom followed by folded ham slices, cooked bacon, and another slice of cheese. The cheese on both the bottom and top creates a melty barrier that prevents the croissant from becoming soggy.
- Bake to golden perfection:
- Place the assembled sandwiches on a baking sheet and bake at 350°F for 10-15 minutes. Watch carefully as croissants can quickly go from golden to overdone. The cheese should be completely melted and the edges of the croissants should be crisp.
- Prepare the eggs:
- While the sandwiches bake, whisk eggs with a splash of milk, salt, and pepper. Melt butter in a nonstick pan over medium heat, then add the egg mixture. Gently stir and fold until eggs form soft curds but remain slightly moist, about 2-3 minutes.
- Complete the sandwiches:
- Remove croissants from the oven and open each sandwich. Add a generous portion of scrambled eggs and sprinkle with fresh chives if desired. Serve immediately while everything is still warm.

The bacon is actually my favorite component in these sandwiches. I discovered its importance accidentally when I made these without it once and my husband immediately noticed something was missing. The smoky crunch against the buttery croissant creates this perfect textural contrast that makes each bite interesting.
Make-Ahead Magic
These sandwiches were designed with meal prep in mind. Assemble everything except the eggs and refrigerate overnight on a baking sheet. The next morning, simply bake as directed while quickly scrambling the eggs. For longer storage, fully assemble with eggs, then wrap individually in plastic wrap. Refrigerate for up to 3 days or freeze for up to a month. When ready to enjoy, thaw overnight if frozen, then reheat in a 350°F oven for 15 minutes or air fryer for 10-15 minutes.
Customization Options
The basic template of these sandwiches invites endless creativity. For vegetarian options replace the meat with sautéed mushrooms, spinach, or roasted red peppers. Experiment with different cheeses like pepper jack for heat or brie for extra creaminess. Try adding avocado slices or arugula after baking for freshness. For a more decadent version, substitute the ham with prosciutto or add a thin layer of fig jam beneath the cheese.
Serving Suggestions
These croissant sandwiches pair beautifully with simple sides that complement without competing. Fresh fruit, especially berries or citrus sections, provide a refreshing counterpoint to the richness. A light arugula salad dressed with lemon and olive oil works wonderfully for brunch service. For beverages, consider mimosas, coffee, or a spicy Bloody Mary. If serving for a gathering, arrange on a wooden board surrounded by clusters of grapes and fresh herbs for an impressive presentation.
The Secret to Perfect Scrambled Eggs
The eggs make or break this sandwich, so proper technique matters. For the silkiest results, remove the pan from heat while the eggs still look slightly underdone; they will continue cooking from residual heat. Avoid overmixing, which creates tough eggs. Instead, gently fold them just until curds form. Season at the end rather than before cooking for the most accurate flavor control. If making multiple sandwiches, consider cooking the eggs in batches rather than crowding the pan.
