These sandwiches came about when my husband was turning forty and I wanted to make him something really special for breakfast without having to wake up at five in the morning. He's one of those people who can never decide between bacon or sausage, so I figured why not just use both? The maple mustard sauce happened because I was rummaging through the fridge looking for something to tie all the flavors together and spotted the maple syrup next to the mustard. Mixing them together was one of those random ideas that turned out to be absolutely perfect.
My neighbor smelled these cooking through the window and came over to ask what was making her kitchen jealous. After trying one, she said it was better than anything she'd had at fancy brunch places in the city. My kids, who normally fight over who gets what for breakfast, were actually sharing bites and discussing how good they were instead of arguing.
Ingredients
- Thick bacon: Baked in the oven so it gets evenly crispy without burning
- Maple breakfast sausage: Shaped into rectangles instead of circles so it fits the croissants better
- Cheesy scrambled eggs: With colby jack mixed right in for extra creaminess
- Good croissants: Toasted so they don't get soggy from all the fillings
- Maple mustard magic: Mayo, mustard, and maple syrup mixed together into liquid gold

Step-by-Step Instructions
- Getting the Bacon Perfect
- Heat your oven to 420 and lay bacon strips on a foil-lined baking sheet. Bake for about 10 to 15 minutes until they're crispy but not burnt. Oven bacon is so much better than pan-fried because it cooks evenly and you don't have grease splattering everywhere.
- Sausage Shaping
- Instead of making round patties, form the sausage into rectangles that will actually fit on the croissants. Cook them in a skillet over medium heat, about 7 or 8 minutes per side until they're cooked through. Keep them warm while you do everything else.
- Egg Magic
- Whisk eggs with milk, salt, pepper, and that shredded cheese in a bowl. Don't cook these until everything else is ready because fresh scrambled eggs are so much better than ones that have been sitting around. When you do cook them, stir constantly with a rubber spatula until they're creamy and just set.
- Croissant Prep
- Split the croissants and toast them under the broiler until they're golden. This step is crucial because it prevents them from turning into soggy mush when you pile on all the fillings.
- The Secret Sauce
- Mix mayo, mustard, and maple syrup together until smooth. Start with equal amounts and adjust based on your taste, more maple if you like it sweeter, more mustard if you want more tang. This sauce is what makes these sandwiches special instead of just regular breakfast sandwiches.
- Putting It All Together
- Spread that sauce on both halves of each croissant, then layer with eggs, sausage, bacon, and a sprinkle of fresh chives. The order matters because it helps everything stay put when you eat it.
I learned about toasting the croissants the hard way after making a batch that fell apart because the bread couldn't handle all the moisture. Now I always toast them and they hold together perfectly. Also, forming the sausage into rectangles instead of circles was a game-changer for getting even coverage.
What to Serve With Them
These are so rich and filling that you don't need much else, but some fresh fruit or crispy hash browns on the side make it feel like a complete meal. Coffee is basically mandatory, though orange juice or mimosas work great too if you're feeling fancy.
Mix It Up
Different cheeses work great in the eggs - try sharp cheddar or pepper jack. You could add some avocado slices for extra richness. The sauce is really adaptable too - try different mustards or add a little hot sauce if you want some heat.
Keeping Them Fresh
These really need to be eaten right away while everything is hot and the croissants are still crispy. You can prep all the components ahead of time and just assemble them when you're ready to eat. That maple mustard sauce keeps in the fridge for days and is amazing on other breakfast foods too.

These breakfast croissant sandwiches have become our special occasion breakfast because they're so completely over the top in the best possible way. Every time I make them, I'm reminded that sometimes the best recipes are the ones that just say "forget about being reasonable" and pile on all the good stuff.
