Croque Madame - a very comforting popular French cafe meal- grill ham and cheese sandwich topped with béchamel sauce, Gruyere cheese and fried egg. An ultimate breakfast meal!
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 and thyme. 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.
Meanwhile, if using a nonstick skillet wipe any crumbs from the pan, then add oil. Heat on medium, add eggs, season with salt and pepper, and cook until whites are cooked but yolks are still runny, about 3 minutes.
If you prefer a more cooked egg cook a little bit longer till desired consistency has been reached. Place an egg on top of each sandwich, and serve hot.
