Pesto alla Genovese
Authentic Pesto alla Genovese, a vibrant and aromatic sauce from the Liguria region of Italy, made with fresh basil, pine nuts, garlic, and two traditional cheeses. Best prepared using a mortar and pestle for optimal texture and flavor.
🧂 Ingredients
- 60 g Fresh basil leaves(Use only the leaves, discard stems. Ensure basil is fresh and vibrant, preferably Genovese basil for authentic flavor. Wash and thoroughly dry the leaves.)
- 30 g Pine nuts(Lightly toasting the pine nuts can enhance their flavor, but it's optional and should be done very carefully to avoid burning.)
- 2 cloves Garlic(Peeled. Adjust quantity to your preference; start with one clove if you prefer a milder garlic flavor.)
- 40 g Parmigiano Reggiano(Finely grated. Use a good quality Parmigiano Reggiano for best results.)
- 20 g Pecorino Sardo (Fiore Sardo)(Finely grated. This sheep's milk cheese adds a distinct tang. If unavailable, use more Parmigiano Reggiano.)
- 100 ml Extra virgin olive oil(A high-quality, fruity extra virgin olive oil is crucial for the flavor profile.)
- 1 pinch Coarse sea salt(To help grind the garlic and prevent basil oxidation.)
👨🍳 Instructions
- 1
Prepare the garlic and salt: Place the peeled garlic cloves and a pinch of coarse sea salt into a mortar. Using the pestle, pound and grind the garlic against the sides of the mortar until it forms a smooth paste. The salt helps to break down the garlic and prevents it from becoming bitter.
⏱️ 2 minutes - 2
Add the basil: Gradually add the fresh basil leaves to the mortar, a handful at a time. Crush the basil against the sides of the mortar with a gentle, rotating motion of the pestle. Continue until all the basil is incorporated and has formed a vibrant green paste. Avoid over-crushing, which can bruise the basil and turn it dark.
⏱️ 8 minutes - 3
Incorporate the pine nuts: Add the pine nuts to the mortar. Pound and grind them with the pestle until they are well incorporated into the basil paste and the mixture is relatively smooth. You should have a thick, fragrant paste.
⏱️ 3 minutes - 4
Add the cheeses and olive oil: Add the finely grated Parmigiano Reggiano and Pecorino Sardo to the mortar. Stir them in with the pestle or a spoon. Slowly drizzle in the extra virgin olive oil while stirring continuously until the pesto is well combined and has a creamy, emulsified consistency. Taste and adjust seasoning if necessary (though the cheeses are usually salty enough).

💡 Pro Tips
- ✓Using a traditional marble mortar and wooden pestle is highly recommended for achieving the authentic texture and flavor of Pesto alla Genovese. A food processor can be used as a shortcut, but pulse gently to avoid overheating and bruising the basil.
- ✓Ensure basil leaves are completely dry after washing to prevent the pesto from becoming watery and to maintain its vibrant green color.
- ✓To store, transfer the pesto to an airtight container and cover the surface completely with a thin layer of extra virgin olive oil. This prevents oxidation and keeps the pesto fresh. It can be refrigerated for up to 5 days.
- ✓For best results, use the pesto immediately after preparation, or chill it for at least 30 minutes to allow the flavors to meld.
