Croque Monsieur Thermomix recipe – the ridiculously French one so that you can pretend you’re seating at a Parisian café reading Sartre

If you associate croque monsieur with a simple ham and cheese toastie, think again!

A proper croque monsieur, like the one you find in all good boulangeries in France, is made of baked ham and cheese and smothered in a velvety, smooth bechamel sauce.

It is so easy and comforting, makes for super quick dinner and is so damn delicious!

Once you’ve mastered this recipe, the next step is the croque madame – same recipe, just with a fried egg on top.
