How to Make Authentic Spanish Garlic Aioli
โ Jump to RecipeQuick Answer
True Spanish aioli doesn't use mayonnaise. It's a rich, creamy emulsion made purely from fresh garlic, olive oil, and a touch of salt.

In America, 'aioli' usually just means flavored mayonnaise. But in Spain (specifically Catalonia), true *Allioli* translates literally to 'garlic and oil'. It is a powerful, spicy, intensely garlicky emulsion that elevates any tapas spread.
Ingredients You Need
- 4 large cloves of fresh garlic, peeled
- 1/2 tsp coarse sea salt
- 1 cup high-quality extra virgin olive oil
- 1 tsp fresh lemon juice (optional, to stabilize)
Step-by-Step Instructions
1. Place the peeled garlic cloves and coarse sea salt into a mortar and pestle.
2. Pound the garlic and salt into a very fine, smooth paste. The salt acts as an abrasive to break down the garlic.
3. Once you have a completely smooth paste, begin adding the olive oil drop by literal drop while stirring constantly in a circular motion with the pestle.
4. As you stir, the garlic and oil will begin to emulsify and thicken. Once the emulsion forms, you can add the oil in a very thin, steady stream, stirring vigorously.
5. Continue until all the oil is incorporated and the aioli is thick and creamy. If it gets too thick, add a drop of lemon juice or water to thin it out. Serve with patatas bravas or crusty bread.
