How to do it
Boil the pasta water — Big pot, salt it like seawater. Cook spaghetti (200g for 2) al dente. Critical: Scoop out 1 cup of pasta water BEFORE draining!
Make the garlic-oil sauce — Meanwhile: heat 6–8 tbsp good olive oil in a pan (medium heat). Slice 4–6 garlic cloves thinly and fry slowly until golden (3–4 min). Add 1 tsp chili flakes, toast briefly.
The trick: pasta water emulsion — Pour half a cup of starchy pasta water into the pan. Swirl vigorously — oil and water combine into a creamy sauce. That's the entire restaurant secret.
Add pasta, toss, serve — Toss drained spaghetti directly into the pan. Too dry? Add more pasta water (1–2 tbsp). Too wet? Cook a bit longer. Season with salt, pepper, fresh parsley. Serve immediately.
Why this works
Pasta releases starch into the water as it cooks. Starch is a natural emulsifier — it binds oil and water into a silky sauce. Without pasta water you get an oily puddle. With pasta water you get restaurant creaminess. Italian chefs use this trick with every pasta dish.
Good to know
- Never over-brown the garlic — if it turns dark brown, it tastes bitter. Better too light than too dark.
- Use good olive oil — it's the main flavour alongside garlic. Extra virgin, not the cheapest.
- Don't rinse the pasta — the surface starch helps the sauce cling.
- Eat immediately — Aglio e Olio doesn't wait. Pasta goes mushy, sauce gets absorbed.
Variations
- With shrimp: Sear before the garlic — classic upgrade.
- With cherry tomatoes: Halved, seared alongside — adds freshness.
- With anchovies: Dissolve 2–3 fillets in the oil — umami bomb.
- Parmesan on top: Not traditional, but delicious. Italian purists will forgive you.
