Ingredients You’ll Need
Gathering simple, high-quality ingredients is key to bringing out the best flavors and textures in this recipe. Each component, from the croissants to the maple mustard sauce, plays an important role in creating a hearty and satisfying breakfast.
- 4 large croissants, sliced in half: Choose fresh, flaky croissants to provide a buttery and soft base for your sandwich.
- 8 large eggs: The fluffy scrambled eggs add protein and a comforting texture that balances the other layers.
- 2 tablespoons milk: Adding milk to the eggs makes them softer and creamier when scrambled.
- Salt and black pepper to taste: Essential seasoning to enhance the eggs and overall flavor.
- 2 tablespoons butter: For cooking the eggs to a perfect, rich finish and adding a subtle depth.
- 8 slices bacon or breakfast sausage patties, cooked: Provides a smoky, savory element that pairs wonderfully with the sweet mustard sauce.
- 4 slices cheddar or Swiss cheese: Melts beautifully on the eggs and meat, adding creaminess and a mild sharpness.
- 2 tablespoons Dijon mustard: Adds a tangy kick to the maple mustard sauce, balancing sweetness with a touch of heat.
- 2 tablespoons pure maple syrup: The star ingredient of the sauce that brings a delicate sweetness and counterpoints the savory flavors in the sandwich.
How to Make Maple Mustard Croissant Breakfast Sandwich Recipe
Step 1: Prepare the Maple Mustard Sauce
Start by whisking together the Dijon mustard and maple syrup in a small bowl. This simple yet flavorful mixture is what makes the Maple Mustard Croissant Breakfast Sandwich Recipe truly special, providing a sweet and tangy layer that harmonizes the other ingredients.
Step 2: Whisk and Cook the Eggs
In a separate bowl, beat the eggs with milk, salt, and black pepper until well combined. Melt butter in a nonstick skillet over medium heat, then scramble the eggs gently until they are just set and wonderfully fluffy. This careful cooking helps retain moisture and creates the perfect texture for the sandwich.
Step 3: Toast the Croissants
Lightly toast the croissant halves if you like a bit of crispness to contrast their buttery softness. This step is optional but adds an extra layer of texture that enhances the overall bite.
Step 4: Assemble the Sandwiches
Spread a generous layer of the maple mustard sauce on the bottom halves of each croissant. Next, add the scrambled eggs, followed by bacon or sausage, and top each with a slice of cheese. Finish by placing the croissant tops on each sandwich, allowing the residual heat to gently melt the cheese and meld the flavors together.
How to Serve Maple Mustard Croissant Breakfast Sandwich Recipe

Garnishes
Add fresh greens like baby arugula or a sprinkle of chopped chives to brighten the plate and add freshness. A light dusting of cracked black pepper right before serving also gives a nice touch of spice that complements the sandwich perfectly.
Side Dishes
This sandwich pairs wonderfully with fresh fruit salad or roasted breakfast potatoes. The contrast of cool, juicy fruit or crispy potatoes offers a complete and satisfying meal that covers all the perfect breakfast bases.
Creative Ways to Present
Serve the sandwiches open-faced for a more rustic presentation or cut them in half diagonally to make them easier to handle and visually inviting. Wrapping them in parchment paper also makes for a charming and practical brunch presentation if you’re serving guests.
Make Ahead and Storage
Storing Leftovers
If you have any sandwiches left, wrap them tightly in foil or place them in an airtight container and refrigerate. They will keep well for up to 2 days but are best enjoyed fresh for optimum texture and flavor.
Freezing
For longer storage, you can freeze the assembled sandwiches before baking or reheating. Wrap each one individually in plastic wrap and aluminum foil to prevent freezer burn. They can be frozen for up to one month.
Reheating
Reheat sandwiches in a preheated oven at 350°F (175°C) for about 10-12 minutes until warmed through and the cheese has melted again. Avoid microwaving, which can make the croissant soggy and the eggs rubbery.
FAQs
Can I use other types of cheese in this recipe?
Absolutely! While cheddar and Swiss are classic choices, feel free to use gouda, provolone, or even a spicy pepper jack to tailor the flavor profile to your liking.
Is there a vegetarian option for this sandwich?
Yes, you can easily substitute the bacon or sausage with a fried egg, sautéed mushrooms, or even avocado slices for a delicious vegetarian version without sacrificing flavor.
Can I prepare the maple mustard sauce ahead of time?
Definitely. The maple mustard sauce can be made up to two days in advance and stored in the refrigerator. Just give it a good stir before using to recombine any separated ingredients.
What is the best way to toast croissants for this sandwich?
Lightly toasting the croissant halves on a skillet or in a toaster oven yields the best balance of crisp edges and tender center. This prevents sogginess once the sandwich is assembled.
How can I make this recipe gluten-free?
Simply swap the croissants for your favorite gluten-free bread or gluten-free croissant alternatives. The rest of the ingredients remain the same, and the flavor won’t be compromised.
