Equipment
Two small saucepans; Fine sieve; Whisk; Pastry brush; Baking tray; Grill/broiler and oven
Notes
- Flavoured milk: take the milk and cream off the heat near boiling and give the onion, garlic and bay ten minutes to infuse. Strain before making the sauce.
- Roux: cook butter and flour gently to a biscuity smell. Whisk in the warm infusion gradually, stirring as the sauce comes to a gentle boil.
- Bread: grill the buttered side until golden. Spread Dijon and sauce on the reverse side before adding Gruyère and ham.
- Finishing: leave enough béchamel and Gruyère to cover the tops of the two sandwiches. Bake until golden, then serve with the separately mixed mustard mayonnaise.

The croque monsieur has a long place in French café cooking, combining buttered bread, ham and Gruyère in a hot sandwich. Béchamel is one familiar variation, rather than a requirement of every version. The exact origin is uncertain, but the name was already in use when Proust published À l’ombre des jeunes filles en fleurs in 1919.
In the novel, Madame de Villeparisis has ordered croque-monsieur and eggs in cream at the hotel after a concert.
Freud builds hers around a carefully flavoured béchamel. Onion, garlic and bay infuse milk and cream before Dijon and nutmeg are added. The bread is toasted on its buttered side, filled on the other, then baked beneath more sauce and cheese. Sourdough or crusty white bread supports that generous filling, with mustard mayonnaise providing a sharper accompaniment.
