Notes

Recipe tips.

We make sure all sides of the bread are coated with the milk mixture, but not soaked, otherwise the sandwich will get soggy.
The key to a perfectly warm and crisp sandwich is using a sturdy bread like sourdough, brioche, or even a thick-cut sandwich bread.
Mini sandwiches can be made using baguette bread.
To make a Croque Madame, prepare as directed and then top the fried sandwich with a freshly fried egg, preferably with a runny yolk.

Air fryer directions. Preheat the oven to 375-400°F. Prepare the sandwiches as directed, and place them on a parchment-lined baking sheet. Bake for 10-12 minutes, flipping halfway through, then broil on each side for about 1-2 minutes, watching carefully so they don't burn.

Prep ahead of time. You can assemble the sandwiches the day before and store them in an airtight container in the fridge. When ready, whisk the milk and egg, dip the sandwiches, and fry.

Store leftovers in a Ziploc or wrap in tin foil. Keep them in the fridge for 2-3 days or freeze for 1-2 months. Reheat in the oven, toaster oven, skillet, or if you're in a hurry, use the microwave.
