Croque Monsieur – classic French comfort food made with ham and cheese sandwich coated in a delicious made-from-scratch Béchamel sauce then fried to golden crisp perfection. It’s a ham and cheese breakfast/brunch meal on a whole new level!
In a medium saucepan, melt 2 tablespoons butter over medium-high heat; add onions stir for about a minute or until foaming.
Add flour, continue cooking, stirring frequently for about 1 to 2 minutes or until bubbling. Remove saucepan from heat.
Then gently add milk, whisking constantly, until mixture is smooth, add bay leaf . Return saucepan to heat. Keep stirring with a wooden spoon, for 8 to 10 minutes or until sauce comes to the boil, thickens and coats the back of a wooden spoon. Remove from heat. Stir in Parmesan, salt and nutmeg. Transfer to a bowl to cool.
For the Bread
Heat a large cast iron skillet or grill pan until hot, brush with half of the butter then place bread on it and brown each side for about 2 minutes.
Transfer to a baking sheet and repeat with the remaining slices of bread sandwiches using the remaining butter.
Top each sandwich with 2 to 3 slices of ham. Combine half of the Gruyere cheese with the béchamel sauce. Adjust for seasoning. Spread a small amount of the Gruyere sauce on top of the ham and top each with another slice of bread.
Spread the remaining béchamel on top of the sandwich . Sprinkle with herbes de provence or thyme.
Broil on low broil until cheese sauce is bubbling and evenly browned, about 2-3 minutes or less. Check every 30 seconds.
Remove and serve with salad.
