This killer maple mustard croissant breakfast sandwich has become my weekend game-changer, transforming ordinary mornings into special occasions with minimal effort. The combination of buttery croissants with the sweet-savory maple mustard sauce creates a breakfast experience that feels indulgent yet comes together in minutes.

I first created these sandwiches when hosting a surprise birthday brunch for my sister. Everyone requested the recipe before they even finished eating, and now it's become our family's special occasion breakfast tradition.

Ingredients

  • Croissants: Fresh from a local bakery ensure the perfect buttery flakiness that makes these sandwiches extraordinary.
  • Large eggs: Provide protein and create a fluffy layer that balances the rich croissant.
  • Bacon: Cooked until perfectly crisp adds a satisfying crunch and smoky flavor.
  • Maple syrup: Brings natural sweetness that pairs beautifully with the savory elements.
  • Dijon mustard: Offers tangy contrast that cuts through the richness of the other ingredients.
  • Cheddar cheese: Melts beautifully and adds a sharp flavor that ties everything together.
  • Butter: For cooking the eggs ensures they remain moist and flavorful.
  • Salt and pepper: Are essential for properly seasoning the eggs.

Step-by-Step Instructions

Prepare the Croissants:
Slice each croissant horizontally using a serrated knife for clean cuts. Try to keep the top slightly thicker than the bottom to prevent the fillings from soaking through.
Cook the Bacon:
Lay bacon strips in a cold skillet then turn to medium heat and cook until they reach your desired crispness. The slow heating method helps render fat evenly for perfectly crisp results. Transfer to paper towels to drain excess grease.
Create the Maple Mustard Sauce:
Combine maple syrup and Dijon mustard in a small saucepan over low heat. Stir continuously for about 2 minutes until the mixture is well integrated and slightly thickened. Allow to cool for 1 minute as it will continue to thicken.
Prepare the Eggs:
Whisk eggs vigorously with salt and pepper in a bowl until frothy. Melt butter in a nonstick skillet over medium low heat. Pour in eggs and use a spatula to gently fold them as they cook for about 2 minutes until just set but still moist.
Assemble the Sandwiches:
Generously spread the maple mustard sauce on the bottom half of each croissant. Layer 2 slices of bacon broken to fit the croissant followed by a portion of fluffy eggs. Place a slice of cheddar on top of the warm eggs to encourage melting.
Final Touch:
Place the assembled sandwiches on a baking sheet and warm in a 350°F oven for 5 minutes. This step is optional but highly recommended as it melts the cheese perfectly and warms everything through for the ultimate breakfast experience.

The maple mustard sauce is truly the secret weapon in this recipe. I discovered it by accident when I ran out of my usual condiments and had to improvise. The combination was so amazing that it's now something I make in larger batches to use on everything from sandwiches to roasted vegetables.

Make Ahead Options

While these sandwiches are best enjoyed fresh, you can prepare most components ahead of time for quick assembly. Cook the bacon and prepare the maple mustard sauce up to three days in advance. Store both in airtight containers in the refrigerator. When ready to serve, simply warm the bacon in the microwave or oven before assembling. The eggs should be cooked fresh for the best texture and flavor.

Perfect Pairings

These breakfast sandwiches shine on their own but pair beautifully with fresh fruit for a complete meal. A simple berry medley or sliced melon provides refreshing contrast to the rich sandwich. For special occasions, serve alongside a light arugula salad with lemon vinaigrette or a small portion of breakfast potatoes. A freshly squeezed orange juice or hot coffee complements the sweet and savory flavors perfectly.

Customization Ideas

The beauty of these breakfast sandwiches lies in their adaptability. For a spicier version, add a dash of hot sauce to the maple mustard mixture or layer in some thinly sliced jalapeños. Vegetarians can skip the bacon altogether or substitute with avocado slices for creaminess. For a more substantial sandwich, add a thin slice of ham along with the bacon. During summer months, consider adding a slice of ripe tomato or some fresh basil leaves for brightness.
