How to find the best French onion soup in Paris
A great soupe à l'oignon starts with onions cooked slowly until deep brown and sweet, then simmered in a rich stock. It arrives in a heavy bowl, topped with bread and a thick layer of cheese browned under the grill until it bubbles and crackles at the edges. If the onions are pale or the cheese is just melted, it's a shortcut. Each place page below lists what regulars order, so you'll know whether the soup is the star or just a warm-up.
The midnight classic
Onion soup was the late-night fuel of the old Les Halles market, and one brasserie still keeps that tradition alive. Au Pied de Cochon, open around the clock since 1946, serves its soupe à l'oignon gratinée next to grilled pig's trotters and seafood platters; walk in at 3am if you like. Browse our late-night restaurants for more after-hours tables.
Bouillons: the budget bowl
Bouillon Pigalle, a huge Belle Époque-style brasserie that opened in 2017, serves onion soup, bœuf bourguignon and œufs mayonnaise at small prices. Book online, and avoid 6:30 to 8pm, when the pre-show Moulin Rouge crowd fills the room. Bouillon Chartier in the 9th and Le Petit Bouillon Pharamond in the 1st play the same game under historic ceilings. More in our cheap restaurants and traditional restaurants.
Brasseries with character
La Coupole, the Art Deco landmark of Montparnasse, serves onion soup alongside oysters and choucroute. In Saint-Germain, Brasserie des Prés cooks the classics with an eco-responsible label, and Le Comptoir du Relais, Yves Camdeborde's bistro, lists it among its classics; it takes no lunch reservations, so arrive early. Near Place Vendôme, Le Petit Vendôme, open from morning until late, has one too. And at the Hôtel de Crillon, Nonos & Comestibles puts onion soup on a grand brasserie menu; its weekday lunch formula is the smart way in. See our French restaurants.
Where to look, and when
The 6th has the most onion soup on this list, followed by the 1st and the 9th, so start with Saint-Germain in the 6th. Most places are mid-priced. It's a cold-weather dish, perfect after a winter walk, and many brasseries serve all day. Check hours on each page, or filter our restaurants open on Sunday, then open the map to find the nearest bubbling bowl.
