New Orleans Café au Lait is a beverage produced by history as much as by recipe. The chicory addition — which began as wartime rationing and post-blockade economy — became so established in New Orleans café culture that it is now considered authentic rather than approximate.
Origin and history
Chicory root as a coffee extender or substitute has a long European history — particularly in France, where the city of Lille developed chicory cultivation for this purpose in the 18th century. When French colonists established New Orleans in the early 18th century, they brought both their café au lait traditions and their familiarity with chicory.
The critical moment came during the American Civil War (1861–1865), when the Union blockade of Confederate ports cut off coffee supplies to New Orleans. The city's residents extended their limited coffee stocks with roasted chicory, a practice already familiar to French settlers. When the blockade ended and coffee returned, many New Orleanians found they preferred the blended flavour — an acquired taste that became a regional identity marker.
Café Du Monde, established at the French Market in 1862, standardised the chicory café au lait formula and became its global ambassador. It serves only café au lait and hot chocolate, and the queue outside it remains a feature of New Orleans tourism.
Chicory — what it is and does
Chicory root (Cichorium intybus) is roasted at high temperatures until dark brown, then ground like coffee. Its flavour compounds are entirely different from coffee — it contains no caffeine, no chlorogenic acids, and no Maillard-reaction coffee compounds. What it has is:
- Inulin: A natural prebiotic fibre that caramelises during roasting to produce a mild, root-like sweetness.
- Sesquiterpene lactones: Bitter compounds that mirror but differ from coffee's bitterness.
- Roasted aromatics: Woody, earthy, tobacco-like notes at a dark roast level.
In a blend, chicory smooths the harshness of dark-roasted coffee, adds body without caffeine, and produces the specific New Orleans flavour profile.
Technical structure
- Coffee blend: Dark-roasted arabica / robusta blend blended 60–70% with 30–40% roasted chicory. Commercial New Orleans blends (Community Coffee, Café Du Monde, French Market) are pre-blended for ease.
- Brew method: Drip filter or percolator, using slightly higher dose than standard coffee (65–75 g/L) to compensate for chicory's lower soluble yield.
- Milk: Hot steamed full-fat milk, equal volume to coffee.
- Ratio: 1:1 coffee to milk by volume.
- Sugar: Optional — the chicory adds a mild sweetness, so less sugar is typically needed.
Best served as
Very hot, in a large cup or mug, alongside beignets (deep-fried choux pastry dusted with powdered sugar). The classic New Orleans breakfast. Consumed by the large white mug at a marble counter, in the French Quarter, at any hour. Café Du Monde remains open 24 hours.
How to prepare
- Prepare the coffee-chicory blend. Use a pre-blended brand (Café Du Monde, Community Coffee's Café Special) or blend 70% dark-roasted coffee with 30% roasted chicory yourself.
- Brew at slightly higher than normal dose — 65–75 g/L — using a drip machine or percolator. Chicory has a lower soluble yield than coffee, so the blend needs more volume per cup.
- Heat full-fat milk to 65–70 °C — just steaming. Scale to match the coffee: equal parts.
- Pour simultaneously where possible — coffee and milk at the same time — or add coffee then milk to a large, wide cup or bowl.
- Serve hot, in a large white ceramic mug — the Café Du Monde 10 oz white mug is the canonical vessel.
What to avoid
- Espresso as a base. New Orleans Café au lait is specifically brewed coffee — the drip or percolator process extracts differently from espresso and produces the correct flavour profile.
- Skipping the chicory. Chicory is not a cost-cutting measure — it is the defining flavour component. Regular dark roast alone does not produce the same result.
- Boiling the milk. Boiled milk dulls the sweetness. Steamed or scalded (just below boiling) is correct.
- Undershooting the coffee strength. Chicory absorbs water and reduces the effective coffee concentration. Brew stronger than you would for regular café au lait.
Tips
- Café Du Monde brand (available online internationally) is the most direct path to the authentic flavour — it is the blend served at the original New Orleans institution.
- Beignets are not optional. The coffee and the doughnut are a single experience — the powdered sugar from the beignets dusting the dark coffee mug is a New Orleans café signature.
- The chicory level can be adjusted — Café Du Monde and similar brands range from 30–40% chicory. If the flavour is too woody, use a blend with less chicory.
