Who doesn't love a hearty breakfast sandwich? I know I do, and this beautiful croque madame is one of the best.
You may have heard of the croque monsieur, a hearty French sandwich made with Gruyère cheese, ham and Béchamel sauce. As its name suggests, it was created as a sandwich for the gents. I suspect that someone decided that we needed a version for the ladies. Hence the croque madame was born. You will recognize her by the fried or poached egg on top, which is said to resemble a ladies' hat. This is her distinguishing feature! As such, I think it's the perfect sandwich for breakfast or brunch!
We have an entire post dedicated to the croque madame sauce that we are using in this recipe. You can check it out if you would like more information.
You will need the following equipment to make this sandwich (affiliate links):
- Small saucepan. To make the sauce.
- Wire whisk. To make the sauce.
- Baking sheet. To toast the bread and melt the cheese.
- Large skillet (not needed if using a griddle). To cook the eggs.
- Griddle (not needed if using a skillet). To cook the eggs.
For the Sauce
Be sure to check out our post dedicated to this croque madame sauce for more information and tips for making it.
- Unsalted butter (2 tablespoons). Adds flavor and helps to thicken the sauce. You can also use salted butter. If you do, you won't need to add as much salt later.
- All-purpose flour (2 tablespoons). This is used to thicken the sauce.
- Warmed milk (1 cup). Be sure to warm the milk first. Warmed milk will prevent the butter from cooling down and solidifying. Making sure the milk is warm first will keep the sauce nice and smooth.
- Shredded Swiss cheese (¾ cup). You can also use Gruyère cheese, but it is more expensive than Swiss and not as readily available. Classic mornay sauce is traditionally made with Gruyère cheese (source). If you decide to try it, you can usually find it in the gourmet section of your grocery store.
- Dijon mustard (1 teaspoon). Adds flavor and blends very well with the ham and cheese.
- Salt & pepper to taste. You can add as much or as little as you like. Use freshly grated pepper for the best flavor.
For the Sandwich
- French bread or white bread (8 slices). Any firm bread will do.
- Unsalted butter (2 tablespoons). Unsalted to control the salt content in this recipe.
- Large eggs (4). Fried and placed on top of our croque madame sandwiches.
- Salt & pepper. To season the eggs. Adjust to your taste.
- Dijon mustard (4 teaspoons). Adds flavor.
- Thinly sliced Black Forest ham (½ lb). We love Black Forest ham in this recipe. Any thinly-sliced ham will do though.
- Shredded Swiss cheese (¼ cup). Add flavor and texture. We opted for Swiss, instead of the traditional Gruyère, because it's a little more affordable and readily available. Swiss works well for this recipe.

They are basically the same, except a croque madame has a fried or poached egg on top.
It has been said that the egg was added because it resembles a woman's hat, making it a ladies' sandwich.
