Ingredients in Maple Mustard Croissant Breakfast Sandwich

Croissants: Flaky, buttery, golden perfection—the base of your sandwich dreams.

Eggs: Scrambled soft and creamy, or fried if you prefer. They add that rich breakfast vibe.

Cheese: Cheddar, Swiss, provolone, or gouda—anything that melts beautifully.

Cooked Protein (Optional): Think crispy bacon, sausage patties, or sliced deli ham. Veggie bacon or sautéed mushrooms are great too.

Baby Spinach or Arugula (Optional): A fresh pop of green to balance the richness.

Maple Mustard Sauce: A dreamy combo of Dijon mustard, maple syrup, and a pinch of seasoning. Sweet, tangy, and totally addictive.

Instructions

Preheat Your Equipment: If toasting croissants or reheating anything, preheat your oven to 350°F or warm a skillet on medium.

Make the Maple Mustard Sauce: In a small bowl, mix Dijon mustard and maple syrup until smooth. Add a tiny pinch of salt and pepper if you’d like. Set aside.

Cook the Eggs: Scramble or fry your eggs to your liking. If you’re scrambling, keep them soft and creamy for best texture.

Prepare Your Cooking Vessel: If toasting croissants, line a baking sheet with parchment or heat a skillet with a bit of butter.

Assemble the Dish:

1. Slice croissants in half.
2. Spread a generous layer of maple mustard sauce on each side.
3. Layer on cheese, eggs, protein (if using), and greens.
4. Close the sandwich and press gently.

Cook to Perfection: If desired, warm the assembled sandwiches in the oven for 5–7 minutes until the cheese melts and croissant is slightly crisped. Or heat in a covered skillet for a few minutes per side.

Finishing Touches: Slice in half (if you can resist diving in whole) and maybe add a final drizzle of extra maple mustard.

Serve and Enjoy: Serve warm with fresh fruit, a side salad, or just a good cup of coffee.
