This hearty maple mustard croissant breakfast sandwich transforms ordinary mornings into special occasions. The combination of buttery croissants, savory bacon, fluffy eggs, and the sweet-tangy maple mustard sauce creates a breakfast experience that feels indulgent yet comes together quickly.
I created this recipe when hosting a brunch for my in-laws, and it's become our go-to weekend breakfast tradition. Even my picky nephew asks for seconds when these sandwiches are on the menu.
Ingredients
- Fresh croissants the buttery, flaky texture makes all the difference, so splurge on bakery-quality if possible
- Large eggs farm fresh eggs with bright orange yolks provide the best flavor and color
- Bacon thick-cut provides the perfect meaty bite against the soft croissant
- Maple syrup use real maple syrup, not pancake syrup, for authentic flavor
- Dijon mustard adds a sophisticated tang that balances the sweetness
- Cheddar cheese opt for sharp cheddar for more pronounced flavor
- Butter use unsalted so you can control the seasoning
- Salt and pepper freshly ground pepper makes a noticeable difference
Step-by-Step Instructions
- Prepare the Croissants
- Slice each croissant horizontally using a serrated knife. For extra flavor, lightly toast the cut sides in a dry skillet until just golden. This creates a barrier that prevents the croissant from becoming soggy when the fillings are added.
- Cook the Bacon
- Lay bacon strips in a cold skillet, then heat to medium. Cook slowly until they reach your desired crispness, about 8-10 minutes, turning occasionally. Drain on paper towels to remove excess grease. The slow cooking method renders more fat and creates evenly crispy bacon.
- Create the Maple Mustard Sauce
- Combine maple syrup and Dijon mustard in a small saucepan over low heat. Whisk constantly until the mixture thickens slightly, about 3 minutes. The sauce should coat the back of a spoon but still be pourable. This reduction intensifies the flavors and creates the perfect consistency for spreading.
- Prepare the Eggs
- Crack eggs into a bowl and whisk vigorously until frothy. Add salt and pepper. Melt butter in a nonstick skillet over medium-low heat. Pour in eggs and let them set slightly before gently folding with a spatula. Continue folding until eggs are just set but still glossy and moist. Avoid overcooking as they will continue to firm up after removal from heat.
- Assemble the Sandwiches
- Spread a generous layer of maple mustard sauce on the bottom half of each croissant. Layer with two bacon strips, a portion of the scrambled eggs, and a slice of cheddar cheese. Cap with the top croissant half, pressing gently to secure the fillings without crushing the delicate pastry.
- Serve or Warm
- Either serve immediately or place the assembled sandwiches on a baking sheet and warm in a 350°F oven for 5 minutes until the cheese begins to melt. The brief warming melds the flavors and creates a cohesive sandwich experience without compromising the croissant's texture.

The maple mustard sauce is truly the star of this recipe. I discovered it accidentally when I ran out of regular mustard while making ham sandwiches. The maple added such a wonderful dimension that I started experimenting with it in other recipes, and this breakfast sandwich became our favorite application.
Make-Ahead Options
While these sandwiches are best enjoyed fresh, you can prepare components ahead of time to streamline your morning. Cook the bacon and prepare the maple mustard sauce up to three days in advance, storing them in separate airtight containers in the refrigerator. On serving morning, simply reheat the bacon briefly in a skillet or microwave and warm the sauce before assembling your sandwiches with freshly scrambled eggs.
Ingredient Swaps
This versatile recipe welcomes substitutions based on dietary needs or what you have on hand. For a lighter version, use turkey bacon or vegetarian bacon alternatives. Dairy-free cheese works well for those avoiding lactose, though it melts differently than traditional cheddar. For gluten-free diners, quality gluten-free croissants are increasingly available at specialty bakeries, or you can substitute brioche or other gluten-free rolls. The maple mustard sauce can be adjusted with honey instead of maple syrup for a different flavor profile.
Serving Suggestions
These hearty sandwiches pair beautifully with fresh fruit for a complete breakfast. I love serving them alongside a simple berry medley or sliced citrus to cut through the richness. For brunch gatherings, complement these sandwiches with a light arugula salad dressed with lemon and olive oil. If serving for lunch, crispy potato wedges or a cup of tomato soup make excellent accompaniments. For presentation, slice the sandwiches diagonally to showcase the colorful layers of fillings.
The History Behind the Recipe
The breakfast sandwich has evolved significantly from its humble beginnings as a portable meal for workers. Croissants themselves have a storied history dating back to 17th century Austria, though they became famously associated with French cuisine. The combination of sweet and savory flavors in this recipe draws inspiration from classic American breakfast pairings like pancakes with bacon and maple syrup. By incorporating these elements into a handheld format, this recipe honors breakfast traditions while creating something uniquely satisfying for modern tastes.

Common Questions
- → Can I prepare these sandwiches ahead of time?
Yes, you can prepare components ahead of time. Cook the bacon and make the maple-mustard sauce a day before, then store in the refrigerator. Assemble fresh in the morning and warm in the oven for best results. Avoid pre-assembling completely as croissants may become soggy.
- → What's the best way to keep croissants fresh?
For maximum freshness, purchase croissants the same day you plan to make the sandwiches. If needed, store them at room temperature in a paper bag for up to 2 days. Never refrigerate croissants as this accelerates staleness, but you can freeze them for longer storage.
- → How can I make these sandwiches vegetarian?
For a vegetarian version, simply omit the bacon or substitute with meat alternatives like tempeh bacon, vegetarian bacon strips, or even sliced avocado for a different but equally satisfying texture and flavor profile.
- → What cheese works best if I don't have cheddar?
If cheddar isn't available, excellent alternatives include Gruyère for a nutty flavor, Swiss for mildness, Gouda for smokiness, or Havarti for creaminess. The key is selecting a cheese that melts well while complementing the sweet-savory maple mustard flavor profile.
- → Can I adjust the maple-mustard sauce ratio?
Absolutely! The 2:1 ratio of maple syrup to Dijon mustard creates a balanced sweet-tangy flavor, but you can adjust to taste. For a sweeter profile, increase maple syrup; for more tanginess, add more mustard. You can also add a pinch of cayenne for heat or a splash of bourbon for depth.
- → How do I achieve perfectly fluffy eggs?
For the fluffiest eggs, whisk vigorously before cooking to incorporate air. Cook in butter over medium-low heat, stirring gently and constantly. Remove from heat when eggs look slightly underdone as they'll continue cooking from residual heat, resulting in perfectly moist, fluffy eggs.
