Croque Madame Sandwich

Ingredients

• For the béchamel sauce:
• 3 - 4 TBSP unsalted butter, divided
• 2 tablespoons flour
• 1 1/2 cup whole milk
• Nutmeg

Kosher salt to taste

• For the sandwich:
• 2 slices of rustic country bread
• 1 tablespoon Dijon mustard
• 2–3 slices of Gruyère
• 3–4 slices of ham

½ cup of shredded Gruyère

• 1 large egg

Directions

Preheat the broiler.

1. Begin by preparing your béchamel sauce:
2. 1 - Start heating milk in a saucepan
3. 2 - In a separate saucepan, melt 1 tablespoon of the butter.
4. 3 - Once milk is warm and butter is melted, add flour to butter and whisk for a minute or two.
5. 4 - Slowly add milk to butter-flour while whisking continuously until all milk is added and sauce is smooth and lump-free.
6. 5 - Bring to a boil, but then lower to a simmer for a few minutes.
7. 6 - Season with salt and a pinch of nutmeg and cook down for a few minutes, then set aside.
8. Make the sandwich:
9. 1 - Spread a very thin layer of Dijon mustard on both slices of bread
10. 2 - Add sliced Gruyère on each side and ham in the middle.
11. 3 - Melt a pat of butter on your griddle or skillet over medium heat, and grill assembled sandwich until cheese is melted and both sides of the bread are toasty and delicious.
12. 4 - Spread béchamel on top of the sandwich and heap shredded Gruyere on top all the way to the edge of the bread.
13. 5 - Place in the broiler until the cheese is melted and caramelized – but don’t let it burn!
14. The Egg:
15. 1 - Meanwhile, heat ½ tablespoon butter in a small skillet or egg pan over medium heat.
16. 2 - Gently crack an egg into the pan, being careful not to break the yolk.
17. 3 - Cook until white is just done and not “snotty”.
18. 4 - Sprinkle with salt and place on top of the sandwich.
19. Voilà and bon appetit!
