Trofie al Pesto (Ligurian — Hand-Rolled Pasta)
Recco and Camogli, Liguria — ancient hand-pasta tradition; the three-component one-pot preparation is documented in Ligurian cuisine from at least the 18th century
Trofie al pesto is the canonical pasta preparation of Liguria — trofie, a short, tightly twisted pasta rolled by hand, dressed with pesto alla Genovese and accompanied by the characteristic Ligurian combination of green beans and potato cooked in the same pot. The combination of pasta, vegetable, and starch in a single pot, unified by pesto at the moment of serving, is one of the most distinctive pasta traditions in Italy and speaks to the simplicity and resourcefulness of Ligurian coastal cooking. Trofie originate from the Recco and Camogli area east of Genoa, where they have been made by hand for centuries. The pasta is made from flour and water only — no egg — and the shaping requires a specific technique: a small piece of dough is placed against the palm and rolled against the work surface with the other palm in a quick, spiralling motion that simultaneously extends and twists the piece into its characteristic form. Each trofie should be about 4cm long, tapered at both ends, tightly spiralled through the centre — the twist is what grips and holds the pesto against the pasta's surface. The Ligurian tradition of cooking the green beans and waxy potato in the same pot as the pasta achieves a specific result: the potato starch released into the pasta water thickens it, the potato and beans absorb some of the pasta's starch, and the vegetable flavours permeate the cooking water. This enriched water then plays a critical role in the sauce: when drained together, potato, beans, and pasta are dressed immediately with pesto, the pasta water loosening and emulsifying the pesto into a glossy coating. The potato's starchiness acts as a natural emulsifier. The result is fundamentally different from pesto on pasta alone — richer, more cohesive, more complex.

Hand-roll each trofie individually — the spiral twist is not achievable with mechanical extrusion Cook potato and green beans in the same pasta water — the released starches thicken the water and enrich the final sauce Add pesto off the heat — never cook pesto, which destroys its aromatic compounds Dress immediately at service — trofie al pesto does not hold; it must be eaten freshly dressed Use the enriched pasta water to loosen the pesto to a flowing, coating consistency
RECIPE: Serves: 4 | Prep: 45 min | Total: 90 min --- 300 g semola di durum — Italian type 00 100 ml warm water 3 g sea salt 240 ml Pesto alla Genovese — freshly made or high-quality jarred 50 g Parmigiano Reggiano DOP — aged 24 months, grated 15 ml extra virgin olive oil — Ligurian DOP 1 pinch Tellicherry black pepper --- 1. Mound semola on a work surface, create a well, and add warm water and sea salt; gradually incorporate flour with fingertips until shaggy dough forms. 2. Knead by hand for 8–10 minutes, pushing dough away with the heel of your hand, until smooth, elastic, and slightly sticky. 3. Rest dough covered with a damp cloth for 20 minutes at room temperature. 4. Roll dough to 2 mm thickness; cut into thin strands with a fork or pasta wheel, then roll each strand between your palms and work surface to create twisted, rope-like trofie about 4 cm long; lay on semola-dusted parchment. 5. Bring a large pot of salted water to a rolling boil; add trofie and cook for 3–4 minutes until they float and are tender but still al dente. 6. Reserve 120 ml pasta water; drain trofie gently. 7. Warm pesto gently in the serving bowl with 60 ml reserved pasta water to loosen; add drained trofie and toss, adding more pasta water as needed to achieve a silky coating. 8. Finish with Parmigiano Reggiano, a drizzle of olive oil, and Tellicherry black pepper; serve immediately. The potato should be diced into 1.5cm cubes — large enough to remain intact but small enough to cook with the pasta Fine green beans (haricots verts) rather than wide flat beans cook to the right texture in the same time as the pasta For a restaurant service of hand-rolled trofie at scale, pre-shape and freeze — they cook from frozen in the same time as fresh A drizzle of raw Ligurian olive oil over the dressed pasta brightens and adds an aromatic top note The proportion of potato-to-pasta in the serving bowl should be roughly 25% potato — enough to notice, not enough to dominate
Using dried commercial trofie — the rough texture of hand-rolled pasta grips pesto far more effectively Cooking the potato separately — the shared pot is the technique, not a shortcut Adding pesto to a hot pan and tossing over heat — the basil oxidises to an unpleasant bitter flavour Skipping the pasta water — pesto without starch water becomes a dry, clumped coating rather than a smooth sauce Over-salting — Ligurian pesto already contains both Parmigiano and Pecorino; the dish needs minimal additional salt
