Croque Madame

The croque madame is a wonderful version of a croque monsieur with a fried egg on top.  Everything is better with a perfectly fried egg on top!  The egg is cooked with the yolk still runny so it oozes out after the first bite.  Delightful!  If you’re unfamiliar with a croque monsieur, it is basically the French version of grilled ham and cheese sandwich.  This croque madame sandwich is covered in a delicious Gruyère and Parmesan sauce.

Ingredients
  • 3 Tbsp butter, unsalted
  • 3 Tbsp AP flour
  • 2 cups whole milk
  • 12 oz Gruyère, grated
  • ½ cup finely grated Parmesan cheese
  • 1/4 tsp Kosher salt
  • 1/8 tsp black pepper
  • Freshly grated nutmeg, to taste
  • 12 ¾”-thick slices sandwich bread, toasted
  • 6 tbsp. Dijon mustard
  • 12 thin slices cooked ham
  • 2 Tbsp canola oil
  • 6 eggs
  • Prep Time: 10 minutes
  • Cook Time: 12 minutes
  • Total Time: 22 minutes
  • Yield: Makes 6 Sandwiches
Preparation

Make the Mornay Sauce:  Heat butter in a 2 quart saucepan over medium-high heat. Add the flour and cook, whisking, until smooth, about 1 minute. Whisk the milk in and bring to a boil.  Immediately reduce heat to medium-low and let simmer until the sauce thickens, about 7 minutes.

Remove from heat and whisk in ½ cup grated Gruyère and the Parmesan until smooth. Season with salt, pepper, and nutmeg.

Make the Sandwiches: Heat broiler or toaster-oven to high. Place 6 slices bread on a parchment paper lined baking sheet (or lightly buttered), and spread about a tablespoon of mustard over each. Top each slice of bread with 2 slices ham and the remaining Gruyère cheese. Broil until cheese begins to melt, about 2 minutes. Top with remaining bread slices, then top with a good amount of mornay sauce on top of each sandwich. Broil until cheese sauce is bubbling and evenly browned, about 4 minutes.

While the sandwiches are heating in the oven, heat oil in a large nonstick skillet over medium heat. Add eggs and cook until whites are cooked but yolks are still runny, about 3 minutes. Season with salt and pepper.  Place an egg on top of each sandwich, and serve hot.
