Croque Madame

- 16 slices ham, thinly slicied
- 8 thin slices of tomato

Directions
Béchamel Sauce
- Preheat the oven to 425°F and line a baking sheet with parchment paper.
- Melt the butter in a medium-sized pot over medium heat.
- Add shallots and garlic and cook for 30 seconds.
- Add the flour and whisk until completely combined and a roux has formed. Slowly pour in the buttermilk and whisk consistently until the sauce has smoothed and thickened, about six minutes.
- Stir in lemon juice, herbs, Dijon, salt and pepper. Set aside.
Assembly
- Place four slices of toasted sourdough onto a prepared baking sheet and spread béchamel over top ensuring end-to-end coverage.
- Place four pieces of ham onto each slice and top with two slices of tomato. Sprinkle with half the cheese and then top each with the remaining pieces of bread.
- Spread the tops of the sandwiches with the remaining béchamel and sprinkle with the remaining cheese. Bake in the oven until the sandwiches are golden and bubbly, about 20 minutes.
- Remove from the oven and let them cool for a few minutes. Place each Croque on a plate and top with a fried egg and garnish with fresh herbs. Dig in and enjoy!
