Notes
Use leftover croissants for convenience and added flavor.
Try different cheeses like gruyère, mozzarella, or Swiss for variety.
Add sautéed vegetables for extra nutrition.
Make it spicy with hot sauce or red pepper flakes.
Swap croissants for brioche or challah for a twist.
For a sweet version, omit salt, pepper, and cheese, and add berries and cinnamon.
Store leftovers in an airtight container in the fridge for up to 3 days.
Reheat in the microwave (1–2 minutes) or in the oven at 325°F until warmed through.
