The Croque Monsieur Sandwich is a French classic made with ham and cheese, topped with a cheese sauce, then baked before a final broiling.

This upscale French Grilled Cheese Recipe got the picky hubby’s attention. He wasn’t sure how to pronounce the French name, but he definitely won’t forget it! If you’re looking for a lunch recipe to impress, this croque monsieur is the answer!

Croque Monsieur Sandwich

The croque or crispy mister, as it translates from French, is basically a grilled ham and cheese sandwich with a smear of mustard. Gruyere is the cheese of choice and the recipe I selected from Ina Garten included a topping of bechamel with even more Gruyere. Baked then broiled, it is an unpretentious, yet extraordinary treat.

I first made these in 2013, after a trip to France. I cooked only one to photograph, but after the guys took care of my leftovers, they requested more! The chicken parmesan I made for dinner went into the fridge for another night!  Gooey and obviously irresistible, you’ll have to give these croque monsieur sandwiches a try. It’s an out of the ordinary, memorable grilled cheese recipe!

What is a Croque Monsieur?

This “gentleman’s sandwich” was first documented on Parisian menus in 1910. The croque monsieur started out as pub fare or a quick snack. Either baked or fried, this crispy grilled cheese originally contained boiled ham and cheese. Later versions were topped with bechamel and cheese and broiled to make an even tastier grilled cheese recipe!

Here are some of the variations of the Croque-Monsieur sandwich via Wikipedia:

  • Croque madame or croque-à-cheval (topped with a fried or poached egg)
  • Croque provençal (with tomato)
  • Croque auvergnat (with bleu d”Auvergne cheese)
  • Croque gagnet (with Gouda and andouille)
  • Croque norvégien (with smoked salmon instead of ham)
  • Croque tartiflette (with sliced potatoes and Reblochon cheese)
  • Croque bolognese / Croque Boum-Boum (with Bolognese sauce)
  • Croque señor (with tomato salsa)
  • Croque Hawaiian (with a slice of pineapple)
  • “Croque McDo” sandwich at found at French McDonald’s

Our First Tastes of This French Grilled Cheese Recipe

Here’s the story of our first tastes of a croque monsieur. It was a Sunday evening, after a long day of touring the picturesque abbey of Mt. Saint Michel and the Normandy beaches. We ended up on the quiet main drag of Saint-Lô looking for a bite to eat.

We walked by restaurant after restaurant, reading menus, ruling out one spot after the next, as our stomachs growled with hunger, till we finally landed at a pub…where only 3 regulars sat at the bar. Some menus were dusted off…and despite a major language barrier, we all ordered a Croque-Monsieur, a French classic.

As we waited patiently for our meal, I surmised that these French ham and cheese sandwiches were being retrieved from deep inside a freezer, taken from a frost-covered box. Underwhelmed, but starving, we all cleaned our plates. Surely, that was not typical of this famous snack which started appearing in Parisian cafes in 1910. I vowed to make my own when we returned stateside. And now you can, too!

  1. Oh, OK it means “crispy mister”. I used to think of it as Mr’s Croque, whatever croque meant. Sounds like a very delish sandwich 🙂 I guess it would do no harm if I used cheddar, right?

  2. Mmmm so many people love Croque Monsieur and after reading your recipe, I see why 🙂

  3. One of my favorite movies! I LOVE Meryl Streep! These sandwiches look amazing too!! Thanks for sharing!

  4. Liz, you need to go back to France immediately and re-train them how to make this French classic. I had one delicious Croque Monsieur on my very first visit as a teen. Since then, however, my experience has been the cheapest of cheap bread, plastic cheese, plastic ham. It is such a shame when it can be so fantastic when it is done properly – as you demonstrate so well.

  5. There are a lot of terrible croque monsieurs out there, but yours looks to die for! I love Meryl Streep but haven’t seen It’s Complicated yet – I must do soon!

  6. Before I read the post I immediately thought of “It’s Complicated”. It’s one of the movies that keep me company while I’m baking. Ever since that movie I’ve wanted to try the cripsy mister, thanks for sharing the recipe and family pics. I would have very high hopes for dining in France also.

  7. Oh liz, I sure want to try this sandwich. I’ve seen the one from Ina, and somehow I missed the scene in Meryl and Steve’s movie. But yours here has me fixated, no wonder your sons asked for more. I know earlier I mentioned the 4 food groups on the plate, but I got to tell you, I’d forego the two groups on the sides for more…sandwich!

  8. This was such a fun Sunday Supper topic this week. 🙂 Ina Garten’s bechamel version reminds me a little of a Louisiana hot brown. Either way, you can’t go wrong with more creamy, cheesy goodness.

  9. I have never made one of these kinds of sandwiches… now I’m wondering why? It looks fabulous. 🙂

  10. Looks like one can drive on that beach! Nice photos of your family and I enjoyed the foodie tales. I can just imagine you enjoying Nutella crepes with your boys and that lovely view. Too bad about the French classic let down. You made up for it later though and the family was appreciative – so it makes for a good story. 🙂

  11. Great anecdote about your travels. We’ve had similar situations where we’ve searched and searched for that perfect foodie experience while abroad, only to find ourselves starving and settling on something typical or underwhelming. It makes me wonder how to have that perfect “foodie” experience while traveling.

  12. Yikes, Liz, I’m sorry you had mediocre croque monsieurs in France, of all places! Good thing you’re a magician in the kitchen and was able to whip up this decadent, indulgent treat yourself. This looks incredible! I love how you tried to healthy it up w/ the asparagus and strawberries 😉 You’re definitely right – don’t even think about the calories, just enjoy every single bite!

  13. Liz,
    My husband says he eats everything but I’d have to leave out the nutmeg for him to eat these – definitely a picky palate too. They look so good – just the word prosciutto makes my mouth water.

  14. I’ve never made a croque monsieur at home, but of course I’ve had them at plenty of French cafes. That’s got to be one of the best thing about a French cafe, in fact – especially the super-casual sort. Its such a fantastic sandwich.

  15. Ham and cheese go really well together in these sandwich. I am drooling over that cheese sauce! Such sweet family photos!

  16. Lizzy Croque Monsieur is one of myfavorite sandwich and this looks delicious !!!

  17. To be honest, I have never heard of Croque Monsieur. After seeing your pictures and reading the recipe I will have to make one. It really sounds amazing

  18. I love this dish! The Croque Madame — with the egg on top — is pretty good too. Your version looks terrific. And traditional. I often make this more as an open-faced sandwich, with a healthy spread of the sauce on top. Gooey, but good. 🙂

  19. I love that you came home to make your own version of these, Liz! Looks like you’ve perfected them. Putting these on our menu!

  20. I’m always game for trying something new especially when it looks this good.
