Cod, vegetables, and one garlic sauce holding everything together. That is the entire architecture of the grand aïoli, and once you see it, you stop looking for a recipe and start looking for a platter. It is not a dish so much as an arrangement: poached salt cod, a garden’s worth of vegetables cooked separately, hard-boiled eggs, and a bowl of aïoli in the middle doing the job of sauce, seasoning and conversation piece at once. In Provence it is served on one big shared plate, and the meal moves at the speed of the table.
The honest headline is that almost nothing here is cooked with technique. The cod is soaked, not seared. The vegetables are boiled, separately, so each one keeps its color and its dignity. The eggs are timed. The only real work — the only moment where this becomes cooking instead of shopping — is the aïoli itself: garlic pounded to paste with salt, then olive oil added one reluctant drop at a time until the mixture turns to ivory. It takes ten minutes by hand and it cannot be hurried, which is exactly the point of the whole meal.
Why salt cod? Because the church calendar said so. For centuries, Fridays and Lent were lean days — no meat — and preserved fish filled the gap across Catholic Europe. Salt cod reached Provence through the Atlantic cod trade, and the Provençal answer was to dress it in their national perfume: garlic and olive oil. The grand aïoli grew from that logic into a festival dish, and villages still stage aïoli banquets on feast days, long tables, one sauce, no menu.

The one sauce that runs the table
Aïoli is older than mayonnaise as an idea, even if the paperwork is fuzzy — the word itself just means garlic (aï) and oil (oli) in Provençal. The classic version contains no egg at all: it is a pure emulsion of garlic, salt and oil, whipped into a paste by patience. Egg-yolk versions exist and are easier; the purists call them a compromise, the pragmatists call them Tuesday. Both camps agree on one thing: aïoli is made the day it is eaten, by hand if possible, and it is never bought in a jar — a jarred aïoli is a rumor of one.
The salt cod needs a calendar more than a technique. It comes from the sea disguised as a plank, and two days of cold-water soaking — with two or three changes — brings it back to something you would recognize as fish. Skip this and you will serve your guests a salt lick with vegetables.
The recipe
- Soak the cod, 36 to 48 hours. Rinse the fillets, cover with cold water, refrigerate. Change the water two or three times — morning, evening, morning. Taste a sliver at the end: it should be salty like the sea remembers, not like the sea insists.
- Cook the vegetables separately, salting the water. Potatoes: 20–25 minutes from cold water, until a knife slides in without resistance. Carrots: 15–20 minutes. Cauliflower: 10–12 minutes. Green beans: 8–10 minutes, then straight into cold water to keep them green. Each vegetable gets its own doneness; one pot for everything gives you one texture and no pride.
- Boil the eggs, 9 minutes. Exactly. Then cold water, peel, halve at the end.
- Poach the cod. Fresh water (or half milk), barely simmering — around 80 °C176 °F, shivering, not boiling. The fillets need 8–10 minutes; the flesh is done when it turns opaque white and flakes apart under gentle pressure. Lift it out carefully; soaked cod is fragile and you are about to be proud of it.
- Make the aïoli. Pound 6 peeled garlic cloves with a fat pinch of salt in the mortar until you have a smooth paste — no visible garlic, no shortcuts. Add the 300 ml olive oil in a thread, a drop at a time for the first 50 ml, stirring one direction with the pestle. The sauce will suddenly tighten and turn pale: that is the emulsion forming. Continue, a little faster now, finishing with a few drops of lemon juice. If it breaks (looks greasy, weeping oil), stop, whisk in a teaspoon of cold water, and resume more slowly. Food processor is allowed; a mortar is a statement.
- Build the platter. Warm cod in the middle, vegetables in color groups around it, egg halves where a gap needs filling. The aïoli goes in a bowl at the center or in generous spoonfuls across the cod. Serve everything at room temperature — this is the rare feast where nothing is urgent.
How to serve it
Rosé from Bandol, or a white from Cassis — Provence answers the table it raised. Bread is mandatory, not optional: aïoli on bread is a documented pleasure, not a garnish. In Paris, Chez Janou near the Marais keeps Provençal dishes in its repertoire, and the seafood brasseries around Montparnasse will understand a platter request of the same spirit. Better still, this is a lunch to serve at home on a weekend with the windows open — it makes more sense at a table you own.
The cliché
Aïoli is just garlic mayonnaise.
Reality
Mayonnaise is an egg emulsion; classic aïoli is garlic and oil alone, pounded without a yolk in sight. The egg version is easier and fine — but calling it mayonnaise is how recipes lose their point.
