Maple Mustard Croissant Sandwich

The combination of buttery croissants, sweet-tangy maple mustard, crispy bacon, and fluffy eggs creates a breakfast experience that feels indulgent yet comes together quickly for busy mornings.

I first made these sandwiches when hosting a brunch for my in-laws, and they've requested them every visit since. The maple mustard sauce was a happy accident when I ran out of regular maple syrup and needed to stretch what I had left.

Ingredients

• Fresh bakery croissants: provide the perfect flaky, buttery base essential for that authentic café quality
• Large eggs: create the fluffy protein foundation remember to whisk them well for maximum fluffiness
• Crispy bacon: adds that irresistible smoky crunch look for thickcut for the best texture
• Pure maple syrup: provides natural sweetness avoid pancake syrup with artificial ingredients
• Dijon mustard: balances the sweetness with tanginess choose whole grain for extra texture
• Cheddar cheese: melts beautifully and adds richness sharp varieties provide the best flavor contrast
• Butter: for cooking the eggs unsalted gives you better control over the final seasoning
• Salt and pepper: essential for bringing out all the other flavors

Step-by-Step Instructions

Prepare the Croissants:

Slice croissants horizontally with a serrated knife to create a top and bottom half. For extra decadence, lightly butter the cut sides and toast them for 2 minutes until just golden. This creates a barrier that prevents the croissant from becoming soggy when filled.

Cook the Bacon:

Lay bacon strips in a cold skillet then turn to medium heat and cook until they reach your desired crispness, approximately 10 minutes. This slow heating method allows the fat to render properly, creating evenly crisp bacon. Transfer to paper towels to drain excess grease.

Make the Maple Mustard Sauce:

In a small saucepan, combine maple syrup and Dijon mustard over low heat. Whisk constantly until the mixture is well blended and slightly thickened, about 3 minutes. The heat helps the flavors meld together beautifully. Remove from heat and let cool slightly to thicken further.

Prepare the Eggs:

Crack eggs into a bowl and whisk vigorously until frothy. Add salt and pepper and continue whisking. Heat butter in a nonstick skillet over medium heat until melted and bubbling subsides. Pour in eggs and let them set slightly before gently folding with a spatula. Cook until just set but still slightly glossy, about 2 minutes.

Assemble the Sandwiches:

Generously spread the maple mustard sauce on the bottom half of each croissant. Layer with 2 slices of bacon, breaking them to fit if necessary. Divide the eggs evenly among the sandwiches. Top with a slice of cheddar cheese. Place the upper croissant half on top, pressing gently.

Warm and Serve:

For melty cheese perfection, place assembled sandwiches on a baking sheet and warm in a 350°F oven for 5 minutes. This step is optional but transforms the experience by melting the cheese and warming everything through. Serve immediately while hot.

Make Ahead Options

These sandwiches work beautifully for meal prep scenarios. 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 for just a few minutes in the oven. The quality remains almost identical to freshly made versions.

Ingredient Swaps

This recipe welcomes adaptation based on dietary preferences. For a vegetarian version, replace the bacon with sliced avocado or roasted tomato slices. Those avoiding dairy can substitute plant-based cheese alternatives that melt well, such as those made from coconut oil. For a lighter option, use egg whites instead of whole eggs, and turkey bacon creates a leaner profile while still providing that essential smoky flavor.

Serving Suggestions

These sandwiches shine as the centerpiece of a weekend brunch spread. Serve alongside fresh fruit, hash browns, or a simple arugula salad with lemon vinaigrette to cut through the richness. For morning gatherings, create a build-your-own sandwich bar with the components laid out for guests to customize. A mimosa or spicy Bloody Mary makes the perfect companion for a leisurely weekend breakfast experience.

The Perfect Croissant

The foundation of this sandwich lies in selecting the right croissant. Day-old croissants actually work better than fresh ones as they have slightly more structure to support the fillings. Look for croissants with a distinctly flaky exterior and visible layers when torn apart. Smaller, more compact croissants create a better filling-to-bread ratio than oversized ones. If your local bakery offers butter croissants versus margarine versions, always choose the real butter variety for superior flavor.
