Instructions
Preheat oven to 350°F.
Line a baking sheet with parchment paper then set a wire rack on top of that. Place the bacon on the wire rack, and sprinkle each slice with 1 teaspoon of brown sugar. If using, crack some black pepper over each (I highly recommend it). Bake for 25 to 30 minutes. Remove from the oven, then transfer the bacon from the wire rack to a clean sheet of parchment before it has a chance to stick. Leave the oven on.
Meanwhile, make the mornay sauce. Melt 1 tablespoon of butter in a small saucepan over medium heat. Whisk in the flour and cook for 1 to 2 minutes, stirring constantly. Next, whisk in the milk, nutmeg + thyme and continue stirring until the sauce is smooth and creamy and begins to thicken (this takes about a minute). Take the saucepan off the heat and stir in the 1/4 cup of grated gruyere until completely melted. Set aside; it will thicken more as it cools.
Before assembling the sandwiches, set aside 1/4 cup of the 1 cup of gruyere (this will be sprinkled on top when you bake). Set out two slices of brioche. Spread each slice with 1 teaspoon of dijon mustard. Place two slices of bacon on each piece of bread, then half the arugula and half the remaining shredded gruyere. Spread 1 teaspoon of dijon and 1 tablespoon of the mornay sauce on each of the remaining slices of bread, and place on top of the sandwiches.
Melt 1 tablespoon of butter in a non-stick skillet. Add the sandwiches and toast on one side. Carefully flip them over and toast on the other side. Transfer them to a sheet pan. Divide the remaining mornay sauce over the tops of each sandwich and sprinkle with the 1/4 cup of gruyere you set aside earlier. Bake until the sauce and cheese is gooey and melted, about 15 to 18 minutes. (Optional, but you can also broil them for a minute or two at the end.)
Wipe out the skillet with a paper towel. Melt the remaining tablespoon of butter over medium heat. Crack two eggs into the skillet and fry them until the whites are set. (I find it helpful to cover the skillet for a minute or two at the beginning to help the whites set without overcooking the yolks.)
Transfer the sandwiches to plates, top each with an egg, then season with kosher salt and black pepper. Garnish with additional thyme if you like.
