Easy French Cuisine “Croque-Monsieur” Recipe

If you have been following my blog you have heard me talk about growing up as the daughter of a french chef. As a child and young adult, I was raised on the finest of french cuisine and ate at some of the very best french restaurants in the city. All the chefs liked to hang out together, so we would often frequent other restaurants.

One of the dishes my dad would like to treat us to was the “Croque-Monsieur”. He would get so excited to prepare this meal for our family and we, of course loved it. I mean who wouldn’t love a ham and cheese sandwich brushed with butter and topped with a béchamel sauce?

In fact, I don’t ever remember my dad making a traditional grilled cheese sandwich for us, but I do remember being introduced to the grilled cheese sandwich at a friend’s house, and I still make it today 🙂

The Croque-Monsieur (translated as “crunch sir”) is considered bar or cafe food in France, along with snacks like tartines and rillettes, salads, and savory tarts.

A traditional Croque-Monsieur is prepared as a single layer of French ham and Gruyère pressed between two thick slices of bread. They are then filled and topped with béchamel, which makes the whole dish creamier and better. The bread is brushed with butter, and the sandwich cooked on a griddle, toasted under a broiler, or baked so that the cheese melts and the bits of ham and cheese hanging out the side caramelize. The meal is rich, substantial and salty, and best served with a glass of wine or beer.




  • ¼ cup unsalted butter
  • ¼ cup all-purpose flour
  • 1½ cups whole milk
  • 2 tbsp. whole grain mustard
  • ¼ tsp. ground nutmeg
  • Kosher salt


  • 8 slices ½” thick country-style bread
  • 6 oz. ham, preferably Paris ham (about 8 slices)
  • 4 oz. Gruyère, grated


Begin by making the béchamel.

fullsizeoutput_85caRemove from heat and whisk in mustard and nutmeg, and season with salt.

fullsizeoutput_85d2Preheat oven to 425° and line your baking sheet with parchment paper. Spread the bread with butter, bottom side down. Then spread bread slices with béchamel, evenly dividing and extending all the way to the edges. Place 4 slices of bread, béchamel side up on a baking sheet.

I use this oven every single day to toast, bake, heat up and broil food. I also love the convection feature and use it often when I’m in a hurry. The large interior size of the oven is a definite plus too. This oven is definitely more expensive than probably any toaster oven but I feel it is worth the price.

The following can be prepared ahead of time:

  • Béchamel can be made 1 day ahead. Let cool, press plastic wrap directly onto surface and chill.
  • Sandwiches can be made (but not baked) 1 day ahead. Cover and chill.

I cooked 2 sandwiches in the oven and put 2 others in the refrigerator for the next day.

fullsizeoutput_85d4My daughter loved this dish, she asked if I could make it everyday! And she is a very picky eater! When she asked me about the little round things, I had to fess up that it was mustard. She got that look on her face, like…I can’t eat this anymore…but then I explained to her that this was good mustard, whole grain mustard…a french mustard like Grey Poupon..not like that nasty bright yellow mustard I dislike as well. Then she looked relieved and continued eating while explaining to me that a lot of mustard is grown in France.

Give the recipe a try for your picky eater. Bon Appétit!
