Spaghetti Aglio e Olio
Garlic, olive oil, chilli and parsley coat spaghetti in a sauce that rewards calm heat and good timing.
Authentic Italian01Starting garlic in cool oil draws out flavour before it burns.
02Starchy water turns oil into a sauce that clings.
03Parsley added off heat stays fresh.
Cook it calmly.
- 01
Start the pasta
Cook the spaghetti in well-salted water until 2 minutes short of al dente. Reserve a mug of cooking water.
- 02
Warm the garlic
Put the oil and garlic in a cool wide pan. Warm gently until the garlic is pale gold, then add the chilli.
- 03
Build the emulsion
Move the spaghetti into the pan with 100 ml pasta water. Toss over medium heat until the oil turns glossy rather than greasy.
- 04
Finish
Take the pan off the heat, add parsley and toss again. Taste before adding more salt.
Common mistakes
- Frying garlic over high heat.
- Draining away every drop of pasta water.
- Serving a pool of loose oil.
The detail that changes the dish.
Garlic should smell sweet and nutty, never sharp or bitter. If it turns dark brown, start that part again. Five cloves cost less than a ruined dinner.
Four pantry ingredients, nowhere to hide
Aglio e olio depends on the cook rather than a crowded shopping list. Garlic needs to perfume the oil without scorching, while pasta water turns that oil into a light coating.
The result is savoury and fragrant, with enough chilli to wake up the spaghetti. It should never feel oily or taste of raw garlic.
A humble southern Italian formula
Garlic-and-oil pasta is associated with Naples and the wider south of Italy. Like many pantry dishes, it is better understood as a household formula than a single inventor’s recipe.
Its enduring appeal is practical: dried pasta, oil and garlic keep well, while chilli and parsley bring the dish to life.
Good oil and patient garlic
Thin garlic slices cook evenly and give clear visual cues. Parsley belongs at the end, where its freshness can cut through the oil.

At the table
Serve at once with a green salad. Cheese is not needed.
Later, if needed
Best fresh. Refrigerate for up to 2 days and reheat in a pan with a spoonful of water.
Be realistic
Do not freeze. The small pleasure here is the fresh emulsion.
Frequently asked questions

Add starchy pasta water and toss firmly until the oil and water bind into a glossy coating.
Can I use crushed garlic?+
Sliced garlic is easier to control. Crushed garlic cooks quickly and is more likely to burn.
