3) Ingredients for Maple Mustard Croissant Breakfast Sandwich

2 croissants, sliced in half: I like mine buttery and flaky, the kind that leaves a few crumbs on your shirt no matter how careful you are. You want something sturdy but still tender.

2 teaspoons Dijon mustard: Sharp and smooth, Dijon brings the bite that balances the sweetness of the maple. Don’t skip it—it’s doing heavy lifting here.

2 teaspoons maple syrup: Use the real stuff if you can. It brings warmth and depth that pairs surprisingly well with the tang of the mustard.

2 slices cheddar cheese: Sharp cheddar melts beautifully and adds a nice hit of saltiness. You can try other cheeses, but cheddar always wins in my kitchen.

2 eggs: Fried, scrambled, poached—whatever mood you’re in, the eggs pull everything together. I like mine just set, with a little golden edge on the whites.

2 teaspoons butter or oil: A quick fry for the eggs, maybe a swipe on the croissants if you want them toasted golden. Your call.

Optional: arugula, tomato slices, avocado: These add-ons bring freshness and color. I love the peppery bite of arugula, but use what makes sense for your morning.

4) How to Make Maple Mustard Croissant Breakfast Sandwich

Step 1. Mix the Dijon mustard and maple syrup in a small bowl. This combo is your flavor foundation—sweet, bold, and just a little unexpected.

Step 2. Heat your skillet over medium and drop in the butter or oil. While it warms up, you can split the croissants and start to toast them if you want that golden edge.

Step 3. Crack the eggs into the pan and cook them to your liking. I go for a soft yolk most mornings, but do what feels right. Salt and pepper, of course.

Step 4. Spread that maple mustard mix generously on both halves of each croissant. Don’t skimp—it’s the star.

Step 5. Layer your cheddar on the bottom half of each croissant. Place the warm egg on top, so it helps melt the cheese. Add arugula, avocado, or tomato if you’re using them.

Step 6. Top with the other croissant half. Serve warm, preferably with coffee in hand and a quiet corner to sit in—if life allows.

5) Tips for Making Maple Mustard Croissant Breakfast Sandwich

If your croissants are a little stale, a quick toast in the oven softens them right up and brings back that buttery aroma. You’ll thank yourself later.

The maple mustard spread keeps in the fridge for a week, so if you fall in love with it like I did, double the batch. It’s great on grilled veggies, wraps, or even roasted chicken.

Play with the layers. Try smoked salmon instead of eggs, or use a plant-based egg if you’re exploring breakfast ideas vegan eaters will enjoy. Once you’ve got the base down, it’s easy to get creative.

6) Making Maple Mustard Croissant Breakfast Sandwich Ahead of Time

I won’t lie—this sandwich is best fresh. But if you want to prep parts ahead, start with the maple mustard mix. It holds up well in the fridge and spreads even easier cold.

You can also cook the eggs ahead of time and store them in a sealed container. They’ll warm quickly in a skillet or microwave when you’re ready to build the sandwich.

Skip assembling the full sandwich until you’re about to eat. That way, your croissants stay crisp and your cheese melts just right. Trust me on this one.

7) Storing Leftover Maple Mustard Croissant Breakfast Sandwich

If you’ve got a leftover sandwich, wrap it tightly in foil or place it in an airtight container. It’ll keep in the fridge for about a day without losing too much texture.

Reheat it gently in a toaster oven or skillet. Microwaves can work in a pinch, but they do make the croissant a bit soggy. Low and slow is the way to go here.

That said, this sandwich isn’t meant to hang around. If you’re making extra, consider storing the components separately so you can assemble fresh later. It’s quick enough to justify that extra step.
