Croque Tartine Parisienne (Egg-Topped Ham and Cheese Sandwich)
Croque tartine parisienne is a decadent ham and melted cheese sandwich is topped with a fried egg.
Yield: serves 4
- 6 tbsp. unsalted butter
- 4 tbsp. flour
- 1 cup milk
- 5 1⁄2 tbsp. Dijon mustard
- 1⁄4 tsp. freshly grated nutmeg
- 8 (1/4"-thick) slices country bread, lightly toasted
- 8 oz. thinly sliced smoked ham
- 16 oz. Gruyère cheese
- 4 eggs
- Crème fraîche, for garnish
- Aleppo pepper, for garnish
- Mixed green salad, for serving (optional)
- Kosher salt and freshly ground black pepper, to taste
- Melt 4 tbsp. butter in a 2-qt. saucepan over medium-high heat. Whisk in flour; cook 2 minutes. Whisk in milk; bring to a boil. Reduce heat to medium-low; cook until slightly thick, making a béchamel sauce, 6–8 minutes. Whisk in 1 1⁄2 tbsp. mustard, plus nutmeg, salt, and pepper; set sauce aside.
- Heat broiler to high. Place 4 slices bread on a baking sheet and spread 1 tbsp. mustard over each. Top each with 2 oz. ham, 2 tbsp. béchamel sauce, and 2 oz. cheese. Broil until cheese begins to melt, 1–2 minutes. Top with remaining bread slices and spread with remaining sauce; sprinkle with remaining cheese. Broil until cheese is browned and bubbly, 3–4 minutes.
- Meanwhile, melt remaining butter in a 12" nonstick skillet over medium heat. Add eggs and season with salt and pepper; cook until whites are cooked but yolks are still runny, about 3 minutes. Place an egg on top of each sandwich, garnish with a dollop of crème fraîche, and sprinkle with Aleppo pepper. Serve with salad on the side, if you like.
