Maple Mustard Croissant Sandwiches are pure breakfast luxury layered between bakery croissants with a sweet sharp sauce crispy bacon gooey cheddar and eggs so fluffy you can taste the comfort in every bite. I love pulling these together on lazy Saturdays when everyone needs something cozy but a little special—this sandwich always hits the spot and has become my go-to for brunches or when I want to treat my crew.
I whipped these up in a rush the first time just working with what was hanging around in my fridge. I tweaked the sauce and got hooked after the first bite. Now my whole family looks forward to these croissants on chilly mornings or as a cozy breakfast-for-dinner treat.
Ingredients
- Fresh large croissants: look for ones with a shiny flaky crust and buttery aroma for the best texture and flavor
- Eggs: pick fresh large eggs so your scramble is light and custardy
- Bacon: cook up quality thick-cut bacon if possible for extra crunch and flavor
- Maple syrup: go for pure maple syrup for a rich earthy sweetness not pancake syrup
- Dijon mustard: choose a smooth mild Dijon to balance the maple and add a gentle heat
- Cheddar cheese: sharp or medium slices melt best on the eggs and bring a gooey savory layer
- Butter: use real butter in the skillet for the eggs so you get soft tender curds
- Salt and black pepper: season your eggs up front for balanced flavor
Step-by-Step Instructions
- Slice the Croissants:
- Carefully split each croissant in half horizontally so you have a sturdy top and bottom and all the flaky layers visible inside
- Crisp the Bacon:
- Cook bacon in a skillet on medium heat until deep golden and crisp then drain on paper towels for maximum crunch
- Make the Maple Mustard Sauce:
- In a small saucepan over low heat mix maple syrup and Dijon mustard stirring until they are combined and just thicken slightly—a minute or so adds shine and stickiness
- Scramble the Eggs:
- Whisk eggs thoroughly with salt and pepper so no streaks remain Melt butter in a nonstick pan over medium low heat Add the eggs and stir gently until just set and still a little glossy which keeps them fluffy and creamy
- Assemble the Sandwiches:
- Spread the warm maple mustard sauce all over the bottom half of each split croissant Arrange two slices of crispy bacon on each base then pile on a scoop of fluffy eggs Top with one slice of cheddar cheese and cap with the croissant lid
- Warm and Serve:
- Set assembled sandwiches on a baking tray and slide into a 350 degree oven for five minutes to melt the cheese and heat through Serve right away for maximum melt

I am completely hooked on the maple Dijon combo here It takes the sandwich from good to restaurant-level special. My family always gathers in the kitchen waiting for the first batch—they know something good is coming when they smell that bacon.
Storage Tips
If you end up with leftovers wrap each sandwich tightly in foil and store in the fridge for up to a day. Reheat in a toaster oven or oven so the croissant stays crisp and the cheese gets gooey again. Avoid microwaving if you want that bakery-fresh texture.
Ingredient Substitutions
Try turkey bacon or even a plant-based option if you want to mix things up. Swap out cheddar for smoked gouda pepper jack or Swiss if you are feeling adventurous. You can also use a honey mustard if you are out of Dijon just add a little less maple syrup so things do not get too sweet.
Serving Suggestions
Pair these with a fresh fruit salad or a handful of arugula on the side for a little freshness. If you are feeding a crowd slice the sandwiches into halves or thirds so everyone can grab a piece on a brunch buffet.

Cultural and Historical Context
The classic French croissant meets all-American breakfast flavors here This mashup is exactly the kind of feel-good food I crave on slow weekends. The sauce is inspired by traditional maple bacon pairings from North American breakfasts but made brunch-worthy for a flaky croissant.
