How to Make the Maple Mustard Croissant Breakfast Sandwiches
Step 1: Prepare the Croissants
Grab your serrated knife and slice those beautiful croissants horizontally. Want to take it up a notch? Lightly butter the cut sides and toast them for about 2 minutes until they’re just golden. This little extra step creates a barrier that keeps your croissant from getting soggy when you add all those delicious fillings.
Step 2: Cook the Bacon
Here’s a game-changing bacon tip: start with a cold skillet! Lay those bacon strips in a cold pan, then turn the heat to medium and let them cook slowly until they reach your perfect level of crispness (about 10 minutes). This method renders the fat properly for evenly crisp bacon every time. Transfer to paper towels to drain, nobody wants a greasy sandwich!
Step 3: Make the Maple Mustard Sauce
This sauce is the secret weapon that makes these sandwiches truly killer! In a small saucepan, combine your maple syrup and Dijon mustard over low heat. Whisk constantly until everything is well blended and slightly thickened, about 3 minutes. The heat helps those flavors meld together in the most magical way. Let it cool slightly, it’ll thicken up even more as it sits.
Step 4: Prepare the Eggs
Crack those eggs into a bowl and whisk them like you mean it , get them nice and frothy! Season with salt and pepper and keep whisking. Melt your butter in a nonstick skillet over medium heat until the bubbling subsides, then pour in those eggs. Let them set slightly before gently folding with a spatula. The secret to perfect scrambled eggs? Take them off the heat when they’re still slightly glossy, they’ll continue cooking from residual heat.
Step 5: Assemble the Sandwiches
Now for the fun part! Generously spread that maple mustard sauce on the bottom half of each croissant, don’t be shy here, it’s what makes these sandwiches special. Layer with bacon (breaking pieces to fit if needed), divide those fluffy eggs evenly among the sandwiches, and top with a slice of cheddar. Crown your creation with the upper croissant half, pressing gently.
Step 6: Warm and Serve
For absolute sandwich perfection, place your assembled masterpieces on a baking sheet and warm in a 350°F oven for about 5 minutes. This melts the cheese into gooey deliciousness and warms everything through. Serve immediately while hot and watch as everyone takes that first bite and goes silent with food bliss!

Notes
Pro Tips for Making the Maple Mustard Croissant Breakfast Sandwiches
- Croissant Selection: Day-old croissants actually work better than super-fresh ones, they have more structure to support the fillings.

- Egg Perfection: Remove eggs from heat when they still look slightly underdone, they’ll continue cooking from residual heat.
- Fresh Element: Add a layer of baby spinach or arugula for a fresh component that balances the richness.

- On-the-Go: Wrap in parchment paper for a portable breakfast that’s infinitely better than drive-thru options.
Make Ahead and Storage
Make Ahead Options
These sandwiches work beautifully for meal prep! You can prepare all components separately up to two days ahead. Store the maple mustard sauce in an airtight container in the refrigerator. Cook the bacon and store between paper towels in a sealed container. When ready to serve, scramble fresh eggs, assemble the sandwiches, and warm them through.
Storing Leftovers
If you happen to have leftover assembled sandwiches (though I doubt you will!), wrap them individually in foil and refrigerate for up to 2 days.

FAQs : Maple Mustard Croissant Breakfast Sandwiches
Can I make these sandwiches vegetarian?
Absolutely! Replace the bacon with sliced avocado, roasted tomatoes, or plant-based bacon alternatives. The maple mustard sauce works beautifully with these substitutions while maintaining that sweet-savory balance.
How can I adjust the sweetness of the maple mustard sauce?
The beauty of this sauce is how customizable it is. For a sweeter profile, increase the maple syrup. If you prefer more tang, add extra Dijon. Start with the recipe as written, then adjust to your taste preferences.
What type of cheese works best if I don’t have cheddar?
Swiss, Gruyère, or Havarti make excellent alternatives to cheddar. Look for cheeses that melt well and have enough flavor to stand up to the other bold ingredients in the sandwich.

Yes! While artisanal bakery croissants provide the best texture and flavor, good-quality store-bought croissants work wonderfully too. Just warm them slightly before using to enhance their buttery flavor and flaky texture.
