Ingredients
- Fresh bakery croissants – 4, halved horizontally
- Large eggs – 4, whisked until frothy
- Thick-cut bacon slices – 8
- Sharp cheddar cheese slices – 4
- Unsalted butter – 2 tablespoons
- Salt – to taste
- Black pepper – to taste
- Pure maple syrup – 3 tablespoons
- Whole grain Dijon mustard – 2 tablespoons (preferably)
Instructions
- Prepare the Croissants
- Using a serrated knife, slice each croissant horizontally. For an extra golden crunch, lightly butter the cut sides and toast them in a skillet or toaster oven for about 2 minutes until they turn beautifully golden.
- Cook the Bacon
- Place the bacon slices in a cold skillet and then turn the heat to medium. Cook slowly until the bacon becomes crisp, about 10 minutes, flipping occasionally. Once cooked, transfer the bacon to paper towels to drain any excess fat.
- Make the Maple Mustard Sauce
- In a small saucepan over low heat, combine the pure maple syrup and Dijon mustard. Whisk continuously until the mixture slightly thickens and blends into a smooth sauce, about 3 minutes. Remove from heat and allow to cool.
- Cook the Scrambled Eggs
- Whisk the eggs with salt and black pepper to taste. Melt the unsalted butter in a nonstick skillet over medium heat. Pour in the eggs and gently fold them with a spatula until they are just set but still soft and creamy, about 2 minutes. Remember, residual heat will finish cooking.
- Assemble the Sandwiches
- Spread a generous layer of the maple mustard sauce on the bottom half of each croissant. Layer 2 slices of crispy bacon, a portion of the scrambled eggs, and a slice of sharp cheddar cheese on top. Finally, cover with the remaining croissant halves.
- Heat and Serve
- Place the assembled sandwiches on a baking sheet and warm them in a preheated 350°F oven for 5 minutes. This step melts the cheese perfectly and heats the sandwich through. Serve immediately for the best experience.
Storage Tips
If you have leftovers, store the sandwiches individually wrapped in the refrigerator for up to 2 days. For best results, reheat them in a 350°F oven until warmed through to revive the crispness of the croissant and melt the cheese evenly.
Serving Suggestions
This sandwich shines when paired with a side of fresh greens like baby spinach or peppery arugula to balance the richness. Add a cup of your favorite coffee or freshly squeezed orange juice to complete a fantastic brunch spread that feels both indulgent and fresh.
Pro Tips
- The maple mustard sauce can be prepared ahead and kept refrigerated for up to two weeks, making meal prep a breeze.
- Using day-old croissants helps maintain the sandwich’s structure without becoming soggy, though fresh ones taste incredible if handled gently.
- Cook your eggs until just set; they will continue cooking with the residual heat once assembled and baked, ensuring creamy texture without dryness.
FAQs
- Can I substitute bacon with another protein?
- Yes! Turkey bacon or Canadian bacon are great substitutes for a leaner option, or try smoked ham for a different flavor profile.
- How can I make the maple mustard sauce spicier?
- Adding a pinch of cayenne pepper or a dash of hot sauce to the maple mustard mixture will provide a subtle kick while keeping the sweetness balanced.
- Can I use a different type of cheese?
- Absolutely! Swiss, Gruyère, or even mozzarella would work well, depending on your preference for meltiness and flavor.
- Is it possible to make this sandwich vegetarian?
- Yes, you can omit the bacon and add sautéed mushrooms or grilled vegetables for a delicious vegetarian alternative.
- What’s the best way to reheat the sandwiches without drying them out?
- Reheat in a 350°F oven wrapped loosely in foil for 10-12 minutes. This will warm them through without drying the croissant or eggs.
- Can I freeze these sandwiches?
- While possible, freezing may affect the texture of the croissants. If you do freeze, wrap tightly and thaw overnight before reheating as described.
