Mousline is a French SAS (société par actions simplifiée) that produces dehydrated mashed potato products for the retail market. The company's core business is manufacturing instant potato flakes (flocons de pomme de terre) that consumers prepare as mashed potatoes by adding water, milk, or butter. Mousline products are sold through French grocery retailers and are positioned as a convenient, family-oriented meal accompaniment.
Founded in 1963 in the Picardy region of northern France, Mousline has produced its potato flakes at the same factory in Rosières en Santerre (Hauts-de-France) for over six decades. The company sources the majority of its potatoes from more than 120 local farmers located within 30 km of the factory.
