For the Sandwich
- Croissants – Buttery and flaky base; opt for bakery-fresh croissants for the best texture.

Step‑by‑Step Instructions for Killer Maple Mustard Croissant Breakfast Sandwiches
Step 1: Prepare Maple Mustard Sauce
In a small bowl, whisk together ½ cup of mayonnaise, 2 tablespoons of your chosen mustard, and 2 tablespoons of real maple syrup until smooth and combined. This sweet and tangy sauce will be the perfect complement to your Killer Maple Mustard Croissant Breakfast Sandwiches. Set the sauce aside to let the flavors meld while you prepare the rest of the ingredients.
Step 2: Cook Bacon
Heat a skillet over medium heat and add thick-cut bacon slices. Cook them for about 4–5 minutes on each side, or until they are crispy and golden brown. Once cooked, remove the bacon from the skillet and let it drain on paper towels. Break the crispy bacon into halves for easy stacking in your sandwiches.
Step 3: Cook Maple Sausage
In the same skillet, add maple breakfast sausage patties. Cook them for 8–10 minutes, flipping them occasionally, until they are browned and fully cooked through. This step allows the flavors from the bacon to enhance your sausage. Once done, remove the sausage from the skillet and let them rest briefly.
Step 4: Scramble Eggs
In a bowl, whisk together 4 large eggs, 2 tablespoons of whole milk, and a pinch of salt and pepper until fully combined. Heat a non-stick skillet over medium-low heat and add the egg mixture, stirring gently with a spatula. Cook for 3–4 minutes until the eggs are fluffy and creamy, but slightly undercooked, keeping the softness perfect for the sandwiches.
Step 5: Warm Croissants
Preheat your oven to 350°F (175°C) while you prepare the croissants. Slice bakery-fresh croissants in half and line them on a baking sheet. Place them in the oven for about 3–4 minutes, just enough time to warm and crisp up the flaky layers. This will create the perfect foundation for your sandwiches.
Step 6: Assemble Sandwiches
Spread a generous amount of the maple mustard sauce on the bottom half of each warm croissant. Next, layer the fluffy scrambled eggs, followed by the cooked sausage patties and crispy bacon pieces. Top each sandwich with a handful of shredded Colby Jack cheese, making a sumptuous stack ready for melting.
Step 7: Melt Cheese
Return the bottom halves of the croissants, now filled with all those delicious layers, to the oven for 1–2 minutes. Keep an eye on them until the cheese is beautifully melted and gooey. This quick step ensures that your Killer Maple Mustard Croissant Breakfast Sandwiches are delightful and warming.
Step 8: Final Assembly and Garnish
Carefully remove the sandwiches from the oven and cap them with the top halves of the croissants. For an extra touch of flavor and color, sprinkle chopped chives on top if desired. Serve your beautiful breakfast sandwiches immediately, and relish the gourmet twist on your morning!

Expert Tips for Killer Maple Mustard Croissant Breakfast Sandwiches
-
Fresh Ingredients: Use bakery-fresh croissants and real maple syrup for the best flavor; stale croissants will compromise the sandwich’s texture.
-
Crispy Bacon: Always cook bacon to a crisp before adding to sandwiches; soggy bacon can make the entire sandwich less enjoyable.
-
Perfect Eggs: Remove scrambled eggs from heat just before they are fully set; this prevents overcooking and keeps them creamy within your Killer Maple Mustard Croissant Breakfast Sandwiches.
-
Cheese Melting: For gooey, melty cheese, use freshly shredded Colby Jack; pre-shredded cheese may not melt as well due to additives.
-
Assemble Quickly: Assemble and serve sandwiches immediately after melting cheese; waiting too long can lead to a soggy bottom from the sauce and moisture.
