Keto Croque Monsieur. 3.8 g of carbohydrates for the entire meal.
Hard to believe, right? “Ce n’est pas possible!” I hear you crying. But yes, it is absolutely possible, with Sandwich bread without carbohydrates and a super simple one béchamel hack.
And no, it’s not a recipe that means hours in the kitchen, even if you have to make the bread from scratch. It doesn’t take long at all.
So if you’re craving to give a ham and cheese sandwich a ‘fancy’ makeover, or are curious to try this famous French dish in ultra-low carb style, I’ve come to the right place.
My version of Croque Monsieur is healthier, faster and just as good as the original. Minus the carbs.
How to Make Keto Croque Monsieur
First of all you have to bake my Sandwich bread without carbohydratesbut alone half of the recipe. You also have to bake it like 6 large flatbreadsas shown in the photos below.
The second step is to toast two buns in a buttered skillet, one at a time, pressing them as they turn golden brown. This only takes a few minutes.
Now stir a bit Dijon mustard in your sour cream. And that’s mine, by the way béchamel hackmy dear readers. It doesn’t matter if you add time, effort and carbohydrates by making a good béchamel sauce. Crème fraîche is a worthy one Keto cheater. Trust me on this.
Yes, yes, I hear you, my French friends. “Croque Monsieur needs bechamel, otherwise it is not the same dish.“Well, yeah, you’re right. But it’s true.” flavors almost the same. Plus, I didn’t deviate too much from the Frenchness, as béchamel and crème fraîche are both French ingredients 😉
Now all you have to do is place one toasted bun on top of the other with the gruyere And cooked ham in the center, and crème fraîche in the center and on top.

Finish with some grated Parmigiano Reggiano and place under the broiler until the center cheese is oozing and the top is a nice, deep caramel color.

And there you have it. Ready to eat. Enjoy!

bake the rolls for 25 minutes and then let them sit on a cooling rack while you mix the crème fraîche with Dijon mustard.
2 rolls, 1 teaspoon Dijon mustard, 80 g crème fraîche
- put half the butter in a small frying pan and toast the first bun on both sides, pressing it with a spatula to flatten it; repeat for the second bun.
20 g unsalted butter
- Place a roll (upside down) on the baking tray, top with half the crème fraîche, then the prosciutto and then the cheese.
60 g Gruyère, 2 slices of cooked ham
stack the second bun on top (again upside down), spread the remaining crème fraîche to the edges and slightly over it (to prevent burning) and brush with Parmigiano Reggiano.
10g Parmigiano Reggiano
- Cut your baking sheet under your oven grill (not too close), set on 200 °C: your croque monsieur is ready when melted cheese runs out and the top has golden brown spots.
best served immediately.
