This French Croque Madame sandwich is by far one of our favorites. The creamy Mornay Sauce is really the shining star in this recipe. This sandwich takes a little longer to make than your average egg sandwich but it is well worth the effort.
What is Mornay Sauce?
Mornay sauce is a bechamel sauce with gruyere, Parmesan or cheddar cheese added. Bechamel sauce is a rich white sauce made by adding milk to a roux. Often other herbs and flavoring are added to complement the final recipe.
How do you make the Croque Madame Sandwich?
How to Make a Mornay Sauce
First, you are going to make the Mornay Sauce. In a small saucepan over medium low heat melt a couple tablespoons of butter. Whisk in an equal amount of flour and cook for a few minutes. Now slowly whisk in the milk and simmer over low heat until slightly thickened. This will take about ten minutes. Remove from the heat and whisk in the gruyére cheese and Parmesan cheese in three parts. Season with salt and black pepper to taste. Cover to keep warm while you assemble the sandwiches.
Assemble the Croque Madame Sandwich
Prepare the sandwiches on a large baking sheet covered with parchment paper. On two toasted slices of bread spread a thin layer of Dijon. Place two slices of ham on one slice. Spoon a couple of tablespoons of Mornay sauce over the ham. Top with the other slice of toast Dijon side down. Now top the whole sandwich with a couple more tablespoons of Mornay sauce mixture. Repeat preparing the other three sandwiches
Complete the Croque Madame with a Fried Egg
Meanwhile, turn the broiler on and start to prepare four eggs sunny side up in a pan. Now pop those sandwiches under the broiler. Watch them closely as everyone’s broiler is different and some are unpredictable. Broil until lightly browned. Finally, top each sandwich with one sunny side up egg. Serve immediately.
Can Mornay Sauce be made ahead of time?
For best results, make the bechamel sauce ahead of time. Store in an airtight container in the fridge. Then reheat slowly over low heat. Add just one to two tablespoons of milk if necessary to thin out. Stir frequently and once hot whisk in your grated cheese. Then proceed with the rest of the recipe.
What is the difference between a Croque Madame and a Croque Monsieur?
Well I thought you would never ask. They are both sandwiches with Dijon mustard, ham and Mornay sauce. They are layered and cooked the same way except that the Croque Madame has a fried or poached egg on the top. Both are equally delicious and considered a treat.
