A staple sandwich in my house is the grilled cheese.

It is delicious on its own, a great breakfast/brunch option, and can be paired with tomato soup for a comforting dinner. I absolutely love that it can be whipped up in minutes with two slices of bread, cheese, and butter. If you want to add a little more to it, then throw in a some thinly sliced ham next to the cheese before cooking. And then you will have yourself something:






Everything that a good grilled ham and cheese sandwich should be. However, if you want to make it fancy and impress your family and friends, then try making a Croque Monsieur.

This is the French version, which includes a simple cheesy white sauce, or béchamel, and some Dijon mustard for a bit of tanginess. The white sauce is spread on the toasted bread slices prior to assembling the ham and cheese sandwich. And if that isn’t enough, after the sandwich is assembled then it is topped with another layer of white sauce, more cheese, and placed under the broiler until the cheese is golden and bubbly.

This sandwich can be made in minutes and is perfect to serve at your next brunch. Your friends and family are sure to enjoy it. Plus you didn’t have to travel to a Parisian café to try it. Be sure to add this recipe to your kitchen toolkit, so that you can have it for those times when you need something simple, delicious, and in a hurry. Also if you would like a similar sandwich recipe, then be sure to give the Croque Madame a try which includes a fried egg.
