Everything you need to know about pasta — shapes, water, salt, cooking times, sauce matching, and the secrets that separate good pasta from great pasta.
Great pasta isn’t complicated, but it does require understanding a few fundamentals. Follow these principles and you’ll make restaurant-quality pasta at home every single time.
The Golden Rules
1. Use a big pot and a lot of water
Pasta needs room to move. Use at least 4 litres of water per 400g of pasta. A crowded pot lowers the temperature when you add pasta, leading to uneven cooking and sticky, clumped results.
2. Salt the water aggressively
Pasta water should taste like the sea. This is not an exaggeration. Use at least 1 tablespoon of salt per litre of water. This is your only opportunity to season the pasta itself — the sauce will never make up for under-salted pasta.
3. Never add oil to the water
Adding oil to pasta water is one of the most persistent myths in home cooking. It makes the pasta slippery and prevents sauces from adhering. Just don’t do it.
4. Cook to al dente
Al dente means “to the tooth” in Italian — pasta that has a slight resistance when bitten. It’s never soft all the way through. Start tasting 2 minutes before the packet suggests and stop when you feel that slight bite.
5. Save your pasta water
Starchy pasta water is liquid gold. It helps emulsify sauces, adds body, and corrects consistency. Always scoop out at least a cup before draining.
6. Finish pasta in the sauce
Never drain your pasta and leave it sitting. Get it straight from the water into the pan with the sauce, add a splash of pasta water, and toss together for 1–2 minutes. The pasta absorbs the sauce and the sauce coats every strand.
Pasta Shapes: A Guide to Matching Sauce
Long and thin (spaghetti, linguine, tagliatelle): Best with olive oil-based, light tomato, or cream-based sauces that can coat each strand. Classic pairings: carbonara, aglio e olio, vongole, puttanesca.
Tubes (rigatoni, penne, paccheri): Their ridges and hollow tubes capture chunky sauces brilliantly. Best with meat ragù, amatriciana, and hearty vegetable sauces.
Small shapes (farfalle, fusilli, orecchiette): Work well with chunky pestos, vegetable sauces, and soups. Their structure holds everything together.
Fresh egg pasta (pappardelle, fettuccine, tagliolini): More delicate than dried — pairs beautifully with butter-based sauces, truffle, and cream.
Dried vs Fresh Pasta
Dried pasta (made from durum wheat semolina and water) is what professional Italian kitchens use for most dishes. It has a more robust texture and holds up to bold sauces. Top brands: De Cecco, Rummo, Garofalo.
Fresh pasta (made with eggs) is more tender, cooks faster (2–3 minutes), and pairs with lighter, more delicate sauces. Best used the same day or within 2 days.
Neither is superior — they’re different tools for different jobs.
Common Pasta Mistakes
- Rinsing pasta after cooking: Never. This washes off the starch that helps sauce adhere.
- Under-salting the water: The biggest flavour mistake in pasta cooking.
- Breaking spaghetti: In Italy, this is practically a crime. Use a longer pot or bend the strands gently as they soften.
- Adding pasta to cold water: Always add to a full, rolling boil.
- Overcooking: Always err on the side of al dente — it continues to cook slightly when tossed in the hot sauce.
The Perfect Pasta Water Ratio
| Pasta | Water | Salt |
|---|---|---|
| 400g (serves 4) | 4 litres | 4 tbsp |
| 200g (serves 2) | 2–3 litres | 2–3 tbsp |
A perfectly seasoned pot of pasta water is the foundation of every great Italian dish.
