Equipment

  • Spatula (for flipping eggs)
  • Oven or toaster (for warming croissants)

Method
 

  1. Preparing the Croissants
  2. Slice the croissants in half and lightly toast them in a pan or oven for a crispier texture.
  3. Cooking the Eggs
  4. Scrambled Eggs: In a bowl, whisk the eggs with salt and pepper. Melt butter in a skillet over medium heat, add eggs, and stir gently until fluffy.
  5. Fried Eggs: Heat a pan with butter, crack the eggs in, and cook until the whites are set but the yolks are still slightly runny.
  6. Assembling the Sandwich
  7. For the Classic Ham & Cheese: Spread mayo or dijon mustard on the croissant base, layer with cheese, ham, and scrambled or fried eggs. Top with the croissant lid.
  8. For the Vegetarian Option: Spread mashed avocado on the bottom half, add cheese, eggs, baby spinach, and red pepper flakes. Close with the croissant top.
  9. For the Smoked Salmon Version: Spread cream cheese on the croissant halves, layer with smoked salmon, avocado slices, red onion, and capers. Sprinkle fresh dill on top.
  10. Melting the Cheese (Optional)
  11. For extra melty cheese, wrap the sandwich in foil and bake at 350°F (175°C) for 5-7 minutes.
  12. Serve & Enjoy!
  13. Serve hot with a side of fresh fruit, a salad, or crispy hash browns for a full breakfast experience.

Notes

Make-Ahead Tip: Assemble the sandwiches, wrap them in foil, and store them in the fridge or freezer. Reheat in the oven at 350°F (175°C) for 15-20 minutes.
Flavor Boost: Try adding hot sauce, pesto, or caramelized onions for extra taste.
Perfect Pairings: Serve with a latte, fresh orange juice, or a mimosa for a deluxe brunch experience.
