Trofie are Liguria's signature hand-rolled pasta—small, thin, twisted spirals of flour-and-water dough (traditionally including a small amount of chestnut flour or boiled potato) that are the canonical pairing for pesto alla genovese, their rough, twisted surface gripping the basil-pine nut-Parmigiano emulsion in every groove. The shape is made by rolling a small piece of dough under the palm on an unfloured board, using a twisting motion that produces a thin, tapered spiral about 3-4cm long, thicker in the middle and pointed at both ends. The twisting technique—rolling forward while pressing and rotating—creates the distinctive helical shape that gives trofie their superior sauce-trapping ability. Traditional trofie from the Golfo Paradiso (the coast between Genoa and Camogli) included chestnut flour, which contributed a subtle sweetness and a slightly grittier texture that complemented the basil pesto. Modern versions use only wheat flour and water, though some add mashed potato for a softer, lighter result. The pairing of trofie with pesto genovese is canonical—the pesto clings to the spirals' rough surface and fills their crevices, while the chewy, dense texture of the pasta provides satisfying resistance against the smooth, creamy sauce. The classic plate adds boiled potato cubes and green beans to the trofie before saucing with pesto—the potatoes softening into the dish and the beans adding colour and crunch. This trio (trofie + pesto + potatoes + green beans) is Ligurian cooking distilled to its essence.
Small, twisted spiral shape rolled under the palm. Flour-and-water dough (sometimes with chestnut flour or potato). Roll on an unfloured surface for grip. The twist creates sauce-trapping grooves. Canonical pairing with pesto genovese. Traditional to add potato cubes and green beans.
The unfloured board is essential—the friction between dough and wood creates the twist. Roll with the base of your palm, not your fingers, pressing forward and slightly rotating. A small addition of mashed potato (about 20% of the flour weight) makes the dough softer and the finished trofie lighter. Trofie dry well and can be stored for weeks. When cooking with potatoes and green beans, add potatoes to the water first, then beans, then trofie, timing so everything finishes together.
Rolling on a floured surface (the dough needs to grip the board to twist). Making them too thick (they should be thin and tapered). Not achieving the twist (practice the rolling-and-pressing motion). Overcooking (they should be chewy, not soft). Pairing with heavy meat sauces (trofie are for pesto and light sauces).
