How to Make Maple Mustard Croissant Breakfast Sandwich
Step 1: Whip Up the Maple Mustard Sauce
Start things off by combining Dijon mustard, maple syrup, and black pepper in a small bowl. Stir until it’s smooth, golden, and gloriously glossy. This magic sauce is the secret behind the signature flavor in your Maple Mustard Croissant Breakfast Sandwich, adding that irresistible sweet-and-sassy bite.
Step 2: Cook the Eggs
Heat butter or oil in a skillet over medium heat. Crack the eggs in—one at a time for picture-perfect results—and cook until the whites are set and the yolks reach your favorite consistency. Prefer a scramble? Go for it! The eggs are your base, so make them just how you love.
Step 3: Prepare the Sausage or Bacon
In a separate pan, cook your breakfast sausage or bacon (vegan or regular) until each side is perfectly golden with just the right crisp. This adds savory heartiness to every bite and takes your sandwich from good to unforgettable.
Step 4: Toast the Croissant Halves
Slice your croissants in half. Toast them cut-side down in a skillet, or use a toaster oven until golden and slightly crisp. This perfectly preps them to handle the fillings and keeps your Maple Mustard Croissant Breakfast Sandwich beautifully structured.
Step 5: Assemble the Sandwich
Spread the maple mustard sauce generously over the bottom half of each toasted croissant. Layer fresh spinach or arugula if you’d like an extra crunch and burst of green. Add your cooked sausage or bacon, a slice of cheddar, and the warm egg. Place the croissant top gently on your masterpiece. Serve while everything is hot and melty!
How to Serve Maple Mustard Croissant Breakfast Sandwich
Garnishes
Dress things up with a few fresh herbs, such as chopped chives or parsley, for color and a touch of garden-fresh flavor. A sprinkle of cracked black pepper on top also adds a beautiful finishing flourish. Add a wedge of lemon or a tiny drizzle of extra maple syrup for an unexpected pop.
Side Dishes
Pair your Maple Mustard Croissant Breakfast Sandwich with crispy hash browns, a light fruit salad, or even a handful of cherry tomatoes for breakfast bliss. If you’re feeling fancy, a simple arugula salad with a little vinaigrette balances out the richness of the sandwich.
Creative Ways to Present
Stack them tall on a wooden board for brunch, or wrap each sandwich in parchment for a grab-and-go breakfast picnic. Slice your sandwiches in halves or quarters for sharing or entertaining, and let people enjoy these beauties as a fun and interactive brunch platter.
Make Ahead and Storage
Storing Leftovers
Wrap any leftover Maple Mustard Croissant Breakfast Sandwich in foil or beeswax wrap and store in the refrigerator for up to two days. The flavors meld even more as they sit, making next-day breakfast a real treat!
Freezing
To freeze, assemble the sandwiches, then wrap tightly in plastic wrap followed by aluminum foil. Store in the freezer for up to one month. Simply thaw overnight in the fridge before reheating for a quick, delicious breakfast on busy mornings.
Reheating
The best way to bring your Maple Mustard Croissant Breakfast Sandwich back to life is in a toaster oven. Heat for about 7-10 minutes at 350°F until piping hot and the cheese is nice and melty. Microwave works in a pinch, but the croissant may lose some crispness.
FAQs
Can I make the Maple Mustard Croissant Breakfast Sandwich vegan?
Absolutely! Swap in plant-based sausage and your favorite dairy-free cheese to enjoy a delicious, fully vegan version without missing any of that signature flavor or indulgence.
What’s the best way to keep croissants crispy after assembling?
Lightly toasting the croissant halves before assembling is key; it gives them resilience against the sauce and fillings, so they stay flakey and wonderful even after adding warm eggs and melty cheese.
Can I use another kind of bread if I don’t have croissants?
While the signature flakiness and rich flavor of croissants really make the Maple Mustard Croissant Breakfast Sandwich stand out, you can absolutely use brioche buns or a hearty baguette if that’s what you have on hand. Just know the texture will be a bit different—still delicious!
How can I add extra veggies to this breakfast sandwich?
Don’t hesitate to pile on sautéed mushrooms, roasted bell peppers, or fresh tomato slices! The spinach or arugula is a great start, but these sandwiches are endlessly adaptable to your vegetable cravings.
What’s the secret to getting perfectly melty cheese?
Add the cheese slice directly onto your eggs during their last minute of cooking. Covering the pan for a bit traps steam and helps the cheese melt seamlessly into everything, creating an oozy, comforting layer in each bite.
Final Thoughts
I can’t wait for you to try this Maple Mustard Croissant Breakfast Sandwich—every bite brings comfort and excitement together in the best breakfast package.
