Genoese basil sauce — DOP basil, Sardo and Parmigiano, Ligurian pine nuts, garlic, oil, pounded in a marble mortar.
Codified in Giovanni Battista Ratto's La Cuciniera Genovese, 1863, though Ligurian basil-and-cheese paste predates it. Genoese DOP basil from Pra' has been protected since 2005; the consortium specifies seven ingredients only.
DOP spec: Genovese DOP basil, garlic from Vessalico, Ligurian extra-virgin, Parmigiano Reggiano 30+ months, Pecorino Sardo, pine nuts (Pisa or Med), coarse sea salt — no other herb. The biennial Pesto World Championship at Palazzo Ducale Genoa has been held since 2007.
Coarse green paste flecked with white cheese and pine-nut shards, glossy from oil. Sweet basil and pungent raw garlic up front, salty cheese mid, pine-nut fat coating the tongue. Tossed through trofie or trenette al dente, never warmed.
Marble mortar and wood pestle — metal blades oxidize basil and turn it black within minutes. Crush garlic and salt first to make a paste, then add basil leaves with rotating wrist motion (not pounding) to bruise cell walls without bruising chlorophyll. Pine nuts, then cheese, then oil drizzled in last.
Variations
DOP Pesto Genovese (Pra' basil, mortar-pounded), Pesto alla Ligure (broader Liguria, looser cheese rules), Pesto alla Trapanese (Sicilian red pesto) — swaps almonds for pine nuts and adds fresh tomatoes and Pecorino, with far less basil, and the Recco-style cheese-heavy version pounded with extra Parmigiano.

How it's made
4 steps · 25 min
- 15 min
Hand-tear leaves from 100 g DOP Genovese basil; rinse, pat dry.
- 25 min
Pound 2 garlic cloves + 50 g pine nuts + pinch salt in marble mortar.
Watch outCrush the garlic, pine nuts and salt to a smooth paste first — the salt grit is your grinding surface, so get this creamy before a single basil leaf goes in.
- 310 min
Add basil leaves in batches, pounding circularly until creamy paste.
Watch outGrind the basil with a circular wrist motion, not pounding — the paste should stay bright green; the moment it darkens toward black you've bruised the leaves too hard.
- 45 min
Work in 60 g Parmigiano + 30 g pecorino Sardo; drizzle 120 ml Ligurian olive oil.
Watch outStir the cheese and oil in off the heat and work fast — friction warms the mortar and warmth dulls the green, so a loose glossy sauce beats an over-worked one.
