Elevate your ham and cheese sliders by adding a bechamel-like sauce to create the most amazing Croque Monsieur Sliders! They are cheesy, flavor-packed, and served on the fluffiest Homemade Hawaiian rolls!
Our latest recipe is our take on the classic ham and cheese slider but it's the more sophisticated, cooler older sibling that studied abroad in France! Our Croque Monsieur Sliders will elevate everything you know about this beloved slider, especially if you make them with our amazing Homemade Hawaiian Rolls! Trust me, whether you make these for a game-day snack or as a way to use up some leftover holiday ham, you will absolutely love them!
- Hawaiian Rolls - I'm sure you all know about this classic that you can buy in the store in the orange bag, but trust me, making them yourself results in a much fluffier, much more delicious, and slider-perfect roll!
- Ham - Sliced deli ham or leftover ham, either is delicious!
- Gruyere and Parmesan Cheese - This combo is perfect for this elevated ham and cheese slider! We suggest sticking to Gruyere, but you could use Swiss or sub the Parmesan for another hard nutty cheese like Asiago or Romano.
- Flour, Butter, Milk, and Salt and Pepper - For the creamy sauce!
- Dijon Mustard - To add just the right kick and perfect compliment! Plus, what's a ham and cheese without the mustard? Have you made your own, yet?
- Fresh Thyme - Just the right savory touch!
So Easy to Make
Slice the Rolls
Once you have your homemade (preferably) Hawaiian Rolls, then it's just a matter of giving them a little slice in half to be able to assemble.
Fill the Sliders
A nice layer of gruyere, plenty of ham, and then another healthy helping of more gruyere cheese before slathering on some Dijon mustard inside the top of your rolls before topping those gorgeous sliders.
Create the Sauce
Very similar to a béchamel sauce, this creamy sauce is made with a roux and milk, but it also has a healthy bit of Parmesan cheese!
Add Sauce and Bake!
Pour that creamy sauce on top, finish with some fresh thyme, and then give those gorgeous Croque Monsieur Sliders a bake!
Until they're gooey and delicious! The perfect combo of sweet rolls, salty ham, cheese, and a creamy cheesy sauce with just a hint of savory thyme.
Friends, your slider game will never be the same, with this one!
While of course, use what you have, trust me, these are so much better if you make your own Hawaiian Rolls. That's because our homemade version makes rolls that are so much fluffier than the store-bought ones. You can also use your other favorite dinner rolls, too, but the sweetness of the Hawaiian Rolls really adds to the whole slider.
Anything you want the best melt with your cheese, always freshly grate it. That's because pre-shredded cheeses have anticlumping agents added and because of that, they won't melt as well as when you shred it yourself.
While our regular Croque Monsieur uses a béchamel sauce, we opted for a béchamel-like sauce for this one because a traditional béchamel sauce does not have cheese and it has a hint of nutmeg. With that said, you could absolutely add the Parmesan cheese to the gruyere and add a touch of nutmeg to the sauce to make it a traditional béchamel.
So my original Hawaiian Rolls recipe calls for making 15 rolls, which you of course can still use for this. When I know I'm making them for sliders, I make bigger rolls and make 12. If you're buying store-bought then they come in packs of 12.
Pro tip: Reheat them in the skillet the next day and make those leftovers into a pressed Croque Monsieur Slider!
