Why Halal checks matter here

Classic Genovese pesto uses Parmigiano and/or pecorino, which are rennet-conditional; jarred pesto hides cheese type; restaurant pasta may be finished with wine.

Herbs, oil, nuts, and garlic are straightforward. The cheese is the Halal question. Make it cheese-free, or name the rennet. See pesto and cheese.

Halal-critical ingredients

  • Parmesan / pecorino Animal rennet is common in traditional hard Italian cheeses. Skip cheese, or use a named microbial/Halal-certified hard cheese.
  • Restaurant finish Some kitchens mount pesto pasta with wine or meat stock. Home oil-and-water only. See Pasta.

Safe substitutes

  • Parmigiano Reggiano of unknown rennet → No cheese, nutritional yeast (flavour only), or microbial-rennet pecorino-style
  • Pine nuts → Walnuts or almonds (still a tree-nut allergen)
  • Wine in the pan → Pasta water

Allergens

gluten, tree nuts (pine nuts), milk (if using cheese)

Ingredients

Pesto

  • 80 g (3 packed cups) fresh basil leaves, dried thoroughly
  • 40 g (⅓ cup) pine nuts, lightly toasted
  • 10 g (2 cloves) garlic
  • 120 ml (½ cup) extra-virgin olive oil
  • 4 g (¾ tsp) fine salt
  • 50 g (½ cup) optional hard cheese with microbial, vegetable, or Halal-certified rennet, finely grated

Pasta

  • 400 g (14 oz) dried linguine or trofie-style short pasta
  • 120 ml (½ cup) pasta cooking water, reserved

Method

  1. Pound or pulse. Crush garlic and salt, then pine nuts, then basil, streaming in oil to a thick sauce. A processor is fine; do not heat the basil. Cheese, if using, goes in last. Cheese-free pesto is Halal on ingredients; classic pesto is only as clear as the cheese. See Pesto, Cheese, and Rennet.
  2. Pasta. Boil pasta in salted water. Reserve starchy water. Do not finish the pan with wine.
  3. Loosen, do not cook the sauce. Toss drained pasta with pesto off the heat, adding spoonfuls of pasta water until it coats. Boiling pesto turns basil dull and is unnecessary.
  4. Jars are a different product. If you ever use jarred pesto instead, read cheese type, whey, and flavourings. This recipe is the home baseline.
