A la bonne franquette is an expression that means “simple, without any fuss, informal”. The word franquette comes from the adjective franc, “frank”, “straightforward”. A la bonne franquette, used since the 17th century, is like saying really simple, but there without any negative connotation! Hier soir, nous avons mangé à la bonne franquette. “Yesterday evening, we had a simple meal.”
