This is part two in an ongoing search for the absolute perfect Grilled Cheese. That sandwich was pretty good, but I was ready to kick these trials up a notch. For that I look for help from the French. Allow me to introduce you to the Croque Monsieur, translated to Mr. Crunchy.

Only the French could think of this amazingly rich creation: A grilled ham and cheese topped with a rich buttery sauce and broiled. In fact there is even a version called the Croque Madame which has a fried egg on top. I’m sure that is yummy but it seemed like overkill to me. A 1,000 calorie sandwich – excellent. A 1,200 calorie sandwich – CRAZY.

So let’s get started. I adapted a version I saw on Ina Garten’s site. The problem is that Ina’s recipe makes enough for like 8 sandwiches. Maybe Ina can eat more than one of these, but I definitely can’t. (Joke Ina. You know I love you.)

Ham and Cheese

The basics of this sandwich starts with a plain Jane ham and cheese sandwich.


I cut pretty thick pieces of bread and toasted them for a few minutes in the oven at 500 degrees. You want them pretty crispy. This is Mr. Crunchy. Not Mr. Schmooshy.

After the toasting, assemble the sandwich. I put mustard on mine, but Betsy doesn’t like mustard and it was good without as well. I put mustard on anything I can because I consider it the dream condiment. You want to use about 1/2 cup of your Swiss inside the sandwich. It acts as a glue.

Ready to bake.

While I worked on my sauce, I let these bake just for a few minutes at 300 degrees just to melt the cheese inside and heat up the ham.


A Bechamel

Now let’s talk  sauce or as the French call it a Bechamel sauce. First thing you need to do for this (and the hardest part) is make a Roux. Basically, it is butter and flour which cooks down a bit and thickens anything you put in it. Good stuff.

After your tablespoon of butter melts, slowly whisk in your flour a teaspoon at a time. It should resemble a paste and start to brown a bit. Don’t go watch a movie or anything while this is cooking, it can very easily burn.

Once the butter has melted and the paste has turned a light, tan color, slowly whisk in your milk. If you pour all your milk in at once, the flour will clump up and you will have milk dumplings. NOT good on a sandwich. So pour slow and you will eventually get a creamy sauce which you should let cook and bubble a bit on low heat for a few minutes.

You want it to be pretty thick. Then add in the rest of your cheeses and season the sauce with salt and pepper and nutmeg if you are being a rebel.

This will be a familiar process to you if you’ve ever made serious baked macaroni and cheese. It is almost the exact same process.

Topping the Sandwiches

Then it is as simple as spooning this amazing sauce over your sandwich…

You can go pretty heavy on topping these guys. It’s very important to toast your bread before you add the sauce or the bread will just get soggy. I probably should’ve toasted mine a bit more honestly.


Then stick the sandwiches under the broiler for 4-5 minutes until the tops are lightly toasted. Watch the sandwiches closely when they are broiling as they can burn quickly. You might need less time than mine.


This was a pretty good sandwich. It’s a fork and knife type of sandwich for sure. It’s possible that I could make it better I think. The bread was a bit thick, but I’m being pretty critical. It was damn good. Let’s judge it on the same qualities as the first sandwich:

Cheesiness: 9. It is tough to imagine a cheesier sandwich. I won’t give it a 10 just so I have room for improvement.

Bread: 7. I think it was a good bread, but I think I cut it a bit too thick. It was also a bit soft. Something with more heft might have worked better.

Fillings: 7. The ham is a good choice. But that is really all that is in it. Not that it needs anything else. The egg might be a good addition.

Overall: 8. An absolutely fantastic, rich sandwich. Great for a Fall afternoon.

Good grilled cheese.

  1. This sandwich looks amazing. I might have a go at trying to make one of these within the next couple of weeks.

  2. Yea. It is very tasty. And not terribly hard to make especially if you are familiar with a Roux.

    Plan for about a 2 hour food coma after you eat it.

  3. I would've never thought to use Roux to crust the cheese up..seems obvious, but never thought of that through my Grilled Cheese trials..

    If you're a fan of pesto, I recently made a grilled cheese with pesto, tomato as my fillers and jack cheddar + prov. cheese as my cheeses. I'd prob. add in bacon as a filler too.

  4. I'm enjoying your blogs! I've made this before – I put bacon and tomato on it – I believe it's called Kentucky Hot Browns. Everything is better with bacon!

  5. Nutmeg makes cheesy things taste cheesier. Hard to believe. All good cheese sauces have a bit of nutmeg in them. Its also in most homemade mac & cheese recipes that are worth a darn. Don’t be afraid of the nutmeg. Just respect it: a little goes a long way.

  6. My mom used to make this awesome sandwich that was ham and cheese on an onion roll and a sauce on the inside made from butter, mustard, Worcestershire and poppyseeds. Then bakes in foil until crispy and cheesy.

  7. Looks like a good spin on croque monsieur. Generally they aren’t covered in a sauce.

  8. Bacon?? Did someone mention BACON??? Everything is at least a little bit better with bacon on it.

  9. I think some kind of fruit preserve would be good with this? Like a chunky blackberry situation?
