Pasta al Pesto Trapanese (Sicilian Almond Pesto Pasta)

From western Sicily, pesto alla trapanese is a brighter, tomato-led cousin of basil pesto, made without cooking so the flavour stays fresh and aromatic. Ripe tomatoes give the sauce juiciness, almonds add gentle sweetness and body, while basil, garlic and extra-virgin olive oil keep it fragrant and savoury. Tossed through hot spaghetti with a little starchy pasta water, the pesto clings lightly rather than becoming heavy, and Pecorino Romano brings a salty finish. It is quick enough for a weeknight dinner but distinctive enough to serve with crusty bread as a simple Italian-style meal.

Why this recipe works

  • Fast fresh sauce: The pesto is blended raw while the pasta cooks, keeping the total time short without sacrificing flavour.
  • Bright but savoury: Ripe tomatoes bring freshness and gentle acidity, while almonds, olive oil and pecorino add body and depth.
  • No direct heat on the pesto: Tossing the sauce with hot pasta and pasta water preserves the basil’s aroma and helps the pesto coat the spaghetti.

Authenticity notes

  • Trapani-style pesto: Pesto Trapanese is associated with western Sicily and is distinct from Ligurian pesto through its use of tomatoes and almonds.
  • Kept raw: The sauce is not cooked separately; the warmth of the pasta is enough to bring the ingredients together.

Ingredient notes

  • Choose ripe tomatoes: Very ripe tomatoes give the pesto sweetness and a fuller texture; underripe tomatoes can make the sauce taste thin and sharp.
  • Check the almonds: Use fresh-tasting almonds, as stale nuts can make the pesto bitter or flat.
  • Account for pecorino: Pecorino Romano is assertively salty, so taste before adding any extra seasoning at the end.

Timing notes

  • Serve straight away: The pesto coats best when tossed with hot pasta and eaten immediately, before the basil flavour dulls.
  • Use the pasta time well: Prepare the tomato, basil and almond pesto while the water comes to the boil and the spaghetti cooks.

Serving ideas

  • Serve with bread: Crusty bread works well for catching any tomato-rich pesto left in the bowl.
  • Finish simply: A final grating of pecorino and a little black pepper keep the finish savoury without masking the basil.

  1. Bring a large pot of water to the boil and season it with 1.5 tsp of the fine sea salt. Meanwhile, cut the tomatoes into chunks and pick the basil leaves.
  2. In a food processor, pulse the almonds and garlic until finely chopped. Add the tomatoes, basil, extra virgin olive oil and the remaining 0.5 tsp fine sea salt, then pulse to a chunky-smooth pesto; scrape down the bowl as needed.
  3. Cook the spaghetti until al dente. Reserve 150 ml of the pasta water, then drain.
  4. Return the spaghetti to the warm pot and add the pesto. Toss well, loosening with a splash of the reserved pasta water until the sauce lightly coats the pasta.
  5. Finely grate in most of the pecorino Romano cheese and toss again. Serve with the remaining pecorino and black pepper over the top.

Tips

  • Keep the pesto raw and fresh: avoid heating it directly, and rely on the warmth of the pasta plus a little pasta water to bring it together.
  • For a sweeter, less watery sauce, use very ripe tomatoes and remove any tough cores before blending.
  • If serving to pregnant people, young children, older adults, or anyone immunocompromised, wash the basil and tomatoes thoroughly before using.

Substitutions

  • Replace Pecorino Romano cheese with Parmesan for a milder, less salty finish.
  • Replace Almonds with Pistachios for a more buttery, distinctly Sicilian-style pesto.

Storage

  • Refrigerate up to 2 days
  • Cool leftovers quickly and refrigerate in a sealed container. Reheat gently with a splash of water or extra virgin olive oil, or eat at room temperature; the basil flavour is best when not overheated.
