Salt and pepper: Season the eggs and bring out all the other flavors.
Colby Jack cheese: Melts into the eggs for a creamy, mild flavor that doesn't overpower the other ingredients.
Croissants: The buttery, flaky pastry is the star here. Toasting them under the broiler adds a nice crunch.
Chives: Add a fresh, mild onion flavor and a pop of color for garnish.

How to Make Breakfast Croissant Sandwiches
Preheat oven: Preheat your oven to 420°F and line a cookie sheet with foil for easy cleanup.
Bake the bacon: Lay the bacon strips flat on the sheet, making sure they don't overlap. Bake for 10-15 minutes, depending on how thick your bacon is, until it's crispy and golden. Transfer to a paper towel-lined plate to drain.
Prepare the sausage: While the bacon bakes, divide the sausage into 6 equal portions and shape each one into a rectangle that'll fit nicely inside a Breakfast Croissant Sandwiches. Heat a skillet over medium and cook the sausages for 7-8 minutes per side until they're browned and cooked through.
Whisk the eggs: In a medium bowl, whisk together the eggs, milk, a pinch of salt and pepper, and the shredded cheese. Pop it in the fridge until you're ready to cook them.
Keep sausages warm: Once the sausages are done, transfer them to a plate and cover with a lid or foil to keep them warm while you finish the rest.
Toast the croissants: Switch your oven to broil. Slice the Breakfast Croissant Sandwiches in half and place them cut-side up on a cookie sheet. Broil for 1-2 minutes until the edges are golden and toasted. Watch them closely so they don't burn.
Cook the eggs: Spray a skillet with cooking spray and heat it over medium-high. Pour in the egg mixture and stir constantly with a rubber spatula, scraping the bottom and sides, until the eggs are just cooked through and still soft. Don't overcook them or they'll get rubbery.
Make the sauce: In a small bowl, whisk together the mayo, mustard, and maple syrup until smooth and well combined.
Assemble the sandwiches: Spread the maple-mustard sauce on both halves of each Breakfast Croissant Sandwiches. Layer the bottom half with scrambled eggs, a sausage patty, a slice of bacon (you can break it to fit), and a sprinkle of minced chives. Top with the other half and serve right away while everything's warm.
Substitutions and Swaps
You can easily adapt this recipe based on what you have on hand.
Sausage: Swap the maple sausage for regular breakfast sausage, turkey sausage, or even a plant-based option if you want to keep it lighter.
Cheese: Colby Jack is mild and melty, but cheddar, Swiss, or pepper jack would all work beautifully here.
Mustard: Yellow mustard, spicy brown mustard, or whole-grain mustard can replace the Dijon if that's what you've got.
Croissants: If you can't find Breakfast Croissant Sandwiches, try this with buttery biscuits, English muffins, or even a soft roll.
Bacon: Turkey bacon or Canadian bacon would work if you want a lighter option.

expert tips
Don't skip the sauce. The maple-mustard sauce is what makes these sandwiches special. It adds moisture and flavor, and it only takes a minute to whisk together.
Shape the sausage carefully. Taking the time to form even rectangles means the sausage fits perfectly inside the Breakfast Croissant Sandwiches and every bite is balanced.
Watch the broiler. Breakfast Croissant Sandwiches can go from golden to burned in seconds under the broiler, so don't walk away while they're toasting.
Cook the eggs last. Scrambled eggs are best when they're fresh and hot, so make them right before you assemble the sandwiches.
Use room-temperature eggs. They cook more evenly and result in fluffier scrambled eggs.
Let the bacon drain. Placing the cooked bacon on paper towels removes excess grease so your sandwiches aren't soggy.
