Yields 4 sandwiches
Oh, the pleasures of lingering over a croque madame in a Parisian café! This decadent sandwich is borrowed from the wonderful French version, and we’ve substituted our delicious—and addictive—duck bacon for the classic ham. This makes a great brunch dish and we recommend using high-quality cheese for the tastiest results. The béchamel should be made ahead of time so that it can chill for at least an hour.
BÉCHAMEL
½ cup whole milk
½ cup heavy cream
Pinch of kosher salt
2 tablespoons butter
2 tablespoons flour
1 teaspoon Worcestershire sauce
½ cup shredded white cheddar cheese
SANDWICH
8 slices sourdough or country white bread
8 slices Gruyère or Swiss cheese
8 slices Duck Bacon, cooked
Butter, for toasting
½ cup shredded white cheddar cheese
½ cup shredded Parmesan cheese
4 eggs
Cracked black pepper
For the béchamel: Heat the milk, cream, and salt together in a microwave or in a saucepan on the stovetop until warm. Slowly melt the butter in a saucepan, and once melted, add the flour and stir until combined. Slowly whisk in the warm milk and cream and bring the béchamel to a simmer. Once thickened and bubbling, add the Worcestershire sauce and ½ cup of the cheddar cheese; stir to combine. Chill in the refrigerator.
To assemble the sandwiches: Preheat the broiler.
Spread a teaspoon or so of the béchamel on both sides of the bread slices. Place 2 slices of Gruyère and 2 slices of duck bacon on one side of the sandwich. Close the sandwich and do the same for the other three.
In a frying pan, using a small amount of butter, toast each side of the sandwich as you would a grilled cheese.
Mix together the cheddar and the Parmesan in a small bowl. Place the toasted sandwiches on a baking sheet and spread liberally with the béchamel covering the entire slice, doing the same with a handful of the shredded cheese. Place the baking sheet under your broiler and cook for 2 to 4 minutes, until the top of the sandwich is bubbling and the cheese becomes a golden brown.
In a small sauté pan, cook each egg sunny-side up with a little butter; the yolks should stay runny. Place one egg on top of each sandwich. Serve with a dash of Worcestershire sauce and cracked black pepper.
