En-cas vs. goûter vs. collation vs. casse-croûte
In French, translation for the word "snack" varies significantly based on the time of day, the person eating, and the level of formality. While en-cas, goûter, collation, and casse-croûte describe eating between main meals, they carry unique cultural connotations ranging from children's rituals to formal breaks and hearty, quick meals.
En-cas
B1Literally meaning "in case," an en-cas is a practical snack eaten to stave off hunger. It is often small, portable, and consumed specifically when one is busy or traveling. It acts as emergency food often kept in a bag or pocket.
J'ai toujours une barre de céréales dans mon sac comme en-cas.
(I always have a cereal bar in my bag as a snack.)
Nous avons pris un rapide en-cas avant d'aller au cinéma.
(We had a quick snack before going to the movies.)
Pour éviter de trop manger au dîner, prenez un léger en-cas vers 17h.
(To avoid overeating at dinner, have a light snack around 5 PM.)
Goûter
A2This is a specific cultural institution in France, referring to the snack eaten around 4 PM (after school). It is primarily associated with children and almost always consists of sweet foods like pastries, chocolate, or fruit. When adults have goûter, it implies a nostalgic or comforting sweet break.
Les enfants rentrent de l'école et demandent leur goûter.
(The kids come home from school and ask for their afternoon snack.)
Grand-mère a préparé un gâteau au chocolat pour le goûter.
(Grandma baked a chocolate cake for the 4 PM snack.)
Même au bureau, on aime faire une pause pour le goûter.
(Even at the office, we like to take a break for a sweet afternoon snack.)
Collation
B2The word collation is the most formal term. It refers to a light snack or refreshment served at official gatherings, conferences, or in medical and dietary contexts (like a hospital meal or a prescribed diet plan). It lacks the emotional warmth of goûter.
Une collation sera servie après la conférence.
(Refreshments will be served after the lecture.)
L'infirmière a apporté une collation au patient.
(The nurse brought a light snack to the patient.)
L'école propose une collation saine aux élèves le matin.
(The school offers a healthy snack to students in the morning.)
Casse-croûte
B2This is an informal, familiar term that literally means "breaking the crust." A casse-croûte is often a hearty, savory snack, such as a sandwich, eaten quickly on a job site, during a hike, or on the road. It can sometimes replace a full lunch meal.
Les ouvriers ont sorti leur casse-croûte à midi.
(The workers took out their lunch snack at noon.)

(We will stop on the highway to eat a quick bite.)
N'oublie pas de préparer un casse-croûte pour la randonnée.
(Don't forget to pack a snack for the hike.)
Summary
To choose the right word: use goûter for a sweet afternoon treat (especially for kids), en-cas for a small item kept just in case of hunger, collation for formal, organized, or medical contexts, and casse-croûte for a hearty, informal savory meal eaten on the go.
