Keto Croque Monsieur

This Keto Croque monsieur is the definition of pure edible bliss. It is prepared with layers of delicious Low-Carb components, making it one of the best French Keto recipes ever. Croque monsieur makes the perfect brunch/lunch option for your special someone.

What is croque monsieur?

Croque monsieur is a decadent ham and cheese sandwich topped with bechamel and baked until golden and crispy. It is an upgraded version of the humble ham and cheese sandwich but enriched with more butter, heavy cream, and cheese. This Keto version is prepared using quick microwave bread, Keto bechamel sauce, ham, gruyere cheese, and parmesan cheese.

How to make the Keto toast bread?

Instead of opting for processed store-bought Keto bread, prepare this quick and healthy microwave bread. Whisk melted butter, egg, egg white, almond flour, baking powder, and salt in a bowl. Transfer it to a small square/rectangular container the size of bread slices, then microwave for 90-120 seconds until firm and cooked through. You can use it immediately or store it in a sealed bag/container in the fridge for 3 days. When ready to make this recipe, slice it in half, fill it with ham and gruyere cheese, top it with the bechamel sauce and parmesan cheese and bake until golden. You can use this bread in any sandwich recipe you prefer.

How to make Keto bechamel

Traditional bechamel sauce contains wheat flour as a thickening agent, which is not Keto-friendly. This recipe depends on the fats from the heavy cream, butter, and cheese for thickness. Add heavy cream and butter to a saucepan and bring to a simmer. Take the saucepan off the heat, add grated gruyere cheese, and whisk until melted—season with mustard, salt, and pepper to taste.

    Really tasty. I used Dijon mustard. Served with an arugula salad. Will make again!

      So tasty! Next time I would also put a smidge of mustard on the meat too.
