There is something so comforting about a breakfast croissant sandwich filled with soft scrambled eggs, crispy bacon, and melty cheddar. This is the kind of breakfast that makes a weekend morning feel special but is quick enough to throw together any day. The combination of flaky croissant and savory fillings is undeniably delicious and satisfies every craving.
My family asks for these every Sunday. Sometimes I have to double the recipe because everyone wants seconds. Once you try it, you might find it landing in your weekly routine too.
Ingredients
- Large croissants: The buttery base of your sandwich Pick the freshest ones you can find or lightly warm day-old croissants
- Large eggs: The main protein For the fluffiest eggs go for free-range or farm fresh
- Cheddar cheese: Melty and tangy The sharper the better Look for a block and slice it fresh
- Cooked bacon: Smoky crunch Thick-cut bacon brings extra flavor and texture Bake it for even crispness
- Butter: Makes eggs extra creamy European-style butter adds richness
- Salt and black pepper: Simple seasoning that brings everything together Use flaky salt if you have it
- Mayonnaise: A creamy spread Adds a touch of moisture Choose real mayo for best taste
- Dijon mustard: Brings a little zip and balance Check the label and pick one made with white wine for a truly French flair
Step-by-Step Instructions
- Warm the Oven:
- Set your oven to three hundred fifty degrees Fahrenheit so you can heat the croissants later This helps revive the flaky texture
- Heat the Skillet:
- Put your skillet on medium heat and let it preheat for one or two minutes The pan should be hot but not smoking before you add the eggs
- Prepare the Eggs:
- Crack eggs into a bowl making sure to keep out any shells Whisk with a fork until the whites and yolks are smoothly mixed and a little frothy
- Melt the Butter:
- Add butter into the warm skillet and gently swirl it to coat the entire surface This ensures the eggs do not stick and stay soft
- Cook the Eggs:
- Pour in the eggs and let them sit undisturbed for about one to two minutes As the edges set gently lift them with a spatula Let any uncooked egg flow to the edges so they finish evenly
- Season and Fold:
- Once the eggs are just cooked sprinkle salt and black pepper over the top Fold the eggs in half or quarters to fit your sandwich
- Slice the Croissants:
- Use a serrated knife to slice croissants horizontally Stop before you cut all the way through so they stay hinged
- Warm the Croissants:
- Arrange croissant halves on a baking sheet cut side up Bake for about five minutes until just warmed and lightly crisp This brings back their fresh bakery flavor
- Add the Spreads:
- While warm spread mayonnaise on the bottom half Dijon mustard on the top half of each croissant Adjust amounts for your taste
- Layer Cheese and Bacon:
- Lay a slice of cheddar on the bottom half followed by a slice of crispy bacon The cheese will soften and melt over the bacon from the warmth
- Add the Eggs and Close:
- Carefully add a portion of eggs on each sandwich Top with the upper croissant half gently pressing so everything stays together
- Serve Warm:
- Enjoy right away while the cheese is melted and the croissant is still flaky

Cheddar is my favorite part of this sandwich The way it melts over the hot eggs and bacon is just perfect One time my daughter tried making it with Swiss and now we have a friendly debate over which cheese is best on Sunday mornings
Storage Tips
Leftover sandwiches keep well wrapped tightly in foil in the fridge for a day Reheat in the oven rather than the microwave to keep the croissant crisp If you want to freeze them assemble without the sauces and wrap tightly then thaw and add spreads after reheating
Ingredient Substitutions
Swap bacon for ham or turkey or go meatless with sautéed spinach or mushrooms If you are out of cheddar try Swiss mozzarella or even a slice of brie For a lighter version use a whole wheat croissant or leave out the mayonnaise
Serving Suggestions
These croissant sandwiches are lovely with a side of fresh fruit or simply a cup of coffee They are also easy to serve for a brunch spread where everyone can add their favorite toppings Sometimes we set up a make-your-own station with different cheeses and spreads

Cultural Context
Croissants bring a classic French touch to this breakfast but the sandwich itself is an irresistible American twist Pairing buttery pastry with eggs and bacon bridges cultures My family loves this spin because it feels both fancy and familiar at once
