Agliata is a bold, savoury garlic sauce that serves as a flavour enhancer, dressing, and condiment. Traditionally, it is paired with roasted or boiled meat, fish, and vegetables, adding an intense aromatic kick to simple dishes. Thanks to its emulsion of olive oil and vinegar, its texture falls somewhere between a vinaigrette and a pesto.
Origins and History
The earliest references to agliata date back to Ancient Rome, where it was already a well-established part of Roman cuisine. Over the centuries, the sauce remained an important element of the culinary traditions of Liguria, the northwestern Italian region whose capital is Genoa.
In the Liber de Coquina (“The Book of Cookery”), a cookbook dating from the 13th and 14th centuries, agliata is recommended as a versatile sauce suitable for almost every type of meat—a testament to its widespread popularity during the Middle Ages.
The name agliata comes directly from the Italian word aglio, meaning “garlic.” In parts of Liguria, the sauce is also known as aggiada.
Traditional Ingredients
Agliata is made from a handful of simple ingredients:
- Fresh garlic, finely crushed or pressed
- Extra virgin olive oil
- Breadcrumbs, preferably made from day-old bread
- White wine vinegar
- Salt and black pepper
How to Prepare Agliata
Begin by soaking the breadcrumbs in white wine vinegar until they become soft, then squeeze out the excess liquid.
Combine the breadcrumbs with the crushed garlic, salt, and pepper to form a smooth base. Gradually whisk in the olive oil while beating continuously with a fork or whisk. This creates a stable emulsion, preventing the oil from separating.
The result is a thick, creamy sauce that can be adjusted to your preferred consistency by adding a little more oil or vinegar.
Regional Variations
Porrata
A little-known variation called porrata replaces garlic with leek (porro in Italian), creating a milder sauce with a delicate onion-like flavour.
Agliata Bianca (White Agliata)
Liguria also has a “white” version made with walnuts, known as agliata bianca or agliata alle noci. This variation is believed to have influenced later Ligurian sauces, including pesto.
Similar Sauces Across Southern Europe
Rouille (France)
Given Liguria’s proximity to Provence, it is no surprise that agliata shares many similarities with the French sauce rouille. This spicy garlic and olive oil sauce is traditionally served with bouillabaisse and other fish dishes and often uses breadcrumbs or potato as a thickener.
Aioli (Spain)
Travelling further west into Catalonia and other parts of Spain, you’ll find the famous aioli (or allioli). Its name literally means “garlic and oil,” referring to the same core ingredients. Although modern aioli is often prepared as a mayonnaise-like emulsion, its historical roots are closely related to those of Italian agliata.
A Legacy of Bold Roman Flavours
Agliata perfectly illustrates the Roman love of strong, assertive flavours—a culinary tradition also reflected in garum, the fermented fish sauce that was once a staple throughout the Roman world.
Today, authentic agliata is still prepared in Liguria and remains a wonderful example of how simple, local ingredients can become a timeless classic. Whether served with roasted vegetables, grilled fish, or meat, it brings an unmistakably Mediterranean character to the table.
For an authentic touch, prepare it with breadcrumbs made from day-old bread—a delicious and sustainable way to make use of leftovers.
