Ingredients
4 slices brioche or white bread
4 slices cooked ham
1 1/2 cups grated Gruyère cheese
2 tablespoons unsalted butter
2 tablespoons all-purpose flour
1 cup whole milk
1/4 teaspoon salt
1/8 teaspoon black pepper
1/8 teaspoon nutmeg
2 large eggs
1 tablespoon butter for frying eggs
Instructions
Preheat oven to 400°F (200°C).
Make béchamel: In a small saucepan, melt 2 tbsp butter over medium heat. Whisk in flour and cook for 1 minute. Gradually whisk in milk, salt, pepper, and nutmeg. Cook, stirring, until thickened, about 2 minutes. Remove from heat.
Place bread slices on a baking sheet. Spread béchamel on each slice. Top two slices with 2 slices ham each, then sprinkle with Gruyère. Place remaining bread slices on top, béchamel side down.
Bake sandwiches for 10 minutes, then flip and bake another 5 minutes until golden and cheese melts.
While sandwiches bake, fry eggs: In a nonstick skillet, melt 1 tbsp butter over medium heat. Crack eggs and cook until whites are set but yolks are runny, about 3 minutes.
Place each sandwich on a plate and top with a fried egg. Serve immediately.
Tips
For a crispier sandwich, toast the bread lightly before assembling.
