Pesto originates from Genoa in the Liguria region of Italy, where it was traditionally made with local basil, pine nuts, garlic, Parmesan, and olive oil using a mortar and pestle. It reflects the Mediterranean emphasis on fresh herbs and high‑quality olive oil and has become a beloved sauce worldwide.

Besides the classic Genovese pesto, other Italian regions use different nuts and herbs: pistachio pesto in Sicily, walnut‑based pesto in Piedmont, and sun‑dried tomato pesto in the south. Each variation showcases local ingredients while keeping the same basic technique.

In Liguria, pesto is most commonly tossed with trofie or trenette pasta and finished with a drizzle of olive oil and a sprinkling of grated Parmigiano‑Reggiano. It is also served on grilled fish or as a topping for bruschetta.

Pesto pasta is a staple at family gatherings, summer picnics, and festive occasions such as Ferragosto and regional harvest festivals in Liguria, where fresh basil is abundant.

The authentic recipe calls for fresh basil leaves, pine nuts, garlic, Parmigiano‑Reggiano (or Pecorino), extra‑virgin olive oil, and sea salt. Substitutes like walnuts or almonds change the flavor profile and are considered regional variations rather than true Genovese pesto.

Pesto pasta pairs beautifully with grilled chicken, roasted vegetables, or a simple Caprese salad. A glass of crisp Vermentino or Ligurian white wine complements the herbaceous sauce.

Common errors include over‑toasting pine nuts (they become bitter), using too much olive oil which makes the sauce heavy, and adding too much pasta water which dilutes the flavor. Follow the critical steps and adjust water gradually for the perfect texture.

The starchy pasta water emulsifies the olive oil and cheese, creating a silky coating without the heaviness of dairy cream. This keeps the dish light, authentic, and lets the fresh basil flavor shine.

Yes, you can prepare the pesto up to two days in advance and keep it in an airtight container in the refrigerator. Store cooked pasta separately; reheat both together with a little extra pasta water to restore creaminess.
