How to cook pasta perfectly every time

Pasta seems like the easiest food in the world: boil water, add pasta, drain. Yet it’s easy to end up with sticky clumps, bland noodles or sauce that slides straight off. A few simple habits make the difference between “fine” and restaurant-quality pasta, and none of them take extra time.

What you need

  • A large pot: about 1 litre of water per 100 g of dried pasta is a good guide.
  • Salt
  • A colander or a pair of tongs or a slotted spoon
  • A mug for saving pasta water

A typical main-course portion is 75–100 g of dried pasta per person.

Step by step

  1. Bring the water to a rolling boil with the lid on to save time and energy.
  2. Salt it well. About 1–2 teaspoons of salt per litre. The water should taste pleasantly seasoned, like a mild soup. This is your only chance to season the pasta itself.
  3. Add the pasta and stir straight away, then again after a minute. The first two minutes are when pieces stick together.
  4. Keep it boiling, lid off. Adjust the heat so it bubbles steadily without boiling over.
  5. Start tasting early, about 2 minutes before the packet time. For “al dente”, the pasta should be tender with a slight firmness in the centre.
  6. Save a mug of pasta water before draining.
  7. Drain, but don’t rinse, and get the pasta into the sauce quickly.

The secret: finish it in the sauce

Restaurant kitchens rarely pour sauce over a pile of plain pasta. Instead, they drain the pasta about a minute early and toss it in the pan with the sauce over a medium heat, adding splashes of the starchy pasta water. The starch helps the oil and liquid in the sauce bind into a glossy coating that clings to every piece. Keep tossing for a minute or two, until the sauce looks creamy rather than watery.

Myths to drop

MythReality
Add oil to stop stickingOil floats on top and makes sauce slide off. Stirring stops sticking.
Rinse pasta after cookingRinsing washes off the starch that helps sauce cling. Only rinse for cold pasta salads.
Salt makes water boil fasterThe amount used barely changes the boiling point. Salt is for flavour.
Throw it at the wall to testTasting is the only reliable test.

Matching shapes and sauces

  • Long, thin pasta (spaghetti, linguine): oil-based, tomato or light cream sauces.
  • Flat ribbons (tagliatelle, pappardelle): rich meat or creamy sauces.
  • Tubes and twists (penne, rigatoni, fusilli): chunky vegetable or meat sauces and bakes.
  • Small shapes (orzo, ditalini): soups and salads.

Fresh and whole-wheat pasta

Fresh egg pasta cooks in just 2–4 minutes, so have your sauce ready first. Whole-wheat and legume pastas often take a little longer and can turn soft quickly once done, so taste frequently.

Leftovers and storage

Cool leftovers quickly and refrigerate within about two hours. Eat within 3–4 days. Reheat with a splash of water in a pan or covered in the microwave until piping hot throughout. If cooking pasta to reheat later, cook it a minute short so it doesn’t go mushy.
