Spaghetti Aglio, Olio e Peperoncino
This spaghetti aglio e olio recipe is the Neapolitan classic in its simplest form: spaghetti tossed with olive oil warmed with sliced garlic, fresh red chilli and parsley, loosened with a splash of starchy pasta water. No cheese — the classic version needs none — just heat, garlic and good oil. One serving is about 263 g.
Spaghetti aglio e olio comes from Naples, where it was the late-night dish of the city's poor — garlic, oil and dried chilli were always in the cupboard, and pasta was always on the stove. It is the purest example of cucina povera, the cooking of making much from little: five cheap ingredients, one pan, and a result that Naples still eats at midnight after a long evening out.
Pairs well with: A bitter-leaf salad, warm bread and a glass of dry white wine

Execution Methodology & Culinary Technique
Prep Stage: Slice the Garlic and Chilli
10 Mins • Slicing & Measuring
Slice the garlic into thin, even rounds and slice the red chilli into rings. Chop the parsley and measure out the oil and chilli flakes. Put a large pot of water on to boil.
Maestro Tip: Slice the garlic evenly: thin slices turn golden together, while mixed sizes mean half the garlic burns before the rest is cooked.
10 Mins Boiling water, 100°C (212°F)
Salt the boiling water and cook the spaghetti for about 2 minutes less than the packet says — it will finish in the oil. Before draining, scoop out 250 ml of the starchy pasta water and set it aside. Drain the pasta but do not rinse it.
The pasta water is what turns plain oil into a sauce that clings: its starch is the whole trick. Save more than you think you need.
Done when: The pasta is bendy but still firm in the middle when you bite it.
4 Mins Low heat, about 120°C (250°F)
While the pasta cooks, warm the olive oil in a wide, deep pan over low heat. Add the sliced garlic and cook gently for about 3 minutes, stirring, until the slices turn pale gold. Keep the heat low — garlic goes from gold to bitter in seconds.
If the garlic colours too fast, lift the pan off the heat at once — the residual heat finishes it without burning.
Done when: The garlic slices are pale gold and the oil smells sweet and fragrant.
1 Min Low heat, about 120°C (250°F)
Add the sliced fresh chilli and the chilli flakes to the pan and cook for about 1 minute more, until the oil takes on a faint red tint and the chilli smells warm.
One minute is enough: chilli cooked longer loses its bright edge and turns dull.
Done when: The oil is lightly tinted and fragrant, and the chilli rings have softened slightly.
3 Mins Medium heat, about 150°C (300°F)
Tip the drained spaghetti into the pan with 120 ml of the hot pasta water. Toss for about 2–3 minutes over medium heat, lifting and turning the strands so every one is coated in the garlicky oil. Add more pasta water a splash at a time if the pan looks dry.
Use tongs and keep the pasta moving — the tossing is what builds the glossy coating, not the heat.
Done when: The pasta is tender and every strand glistens with oil, with no dry clumps in the pan.
2 Mins Serve hot — pasta about 70°C (160°F)
Take the pan off the heat, shower over the chopped parsley and toss once more. Twist the pasta into warm, shallow bowls and serve immediately.
Warm the bowls first with hot water: a cold bowl dulls the shine of the oil in seconds.
Done when: The pasta sits in glossy strands, the parsley is bright green on top, and the oil coats rather than pools.
Finishing Touches & Plating
Twist the glossy spaghetti into warm bowls, spoon over every drop of garlicky oil from the pan, and serve at once — the oil soaks in within minutes, so the table should already be set.

Simple Pantry Ingredients
Five ingredients from the cupboard — spaghetti, olive oil, garlic, chilli and parsley — and nothing you cannot pronounce.
Vegan as Written
No cheese, no butter, no meat — the classic version is vegan as written, and the olive oil is the only fat.
Food Pairings
To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:
Vegetables
Bitter-Leaf Salad
A lightly dressed bitter-leaf salad cuts the richness of the oil and resets the palate.
Sides
Warm Bread
Crusty bread is made for the garlicky oil left in the bowl — it soaks up what the fork misses.
White Beans
A side of white beans adds protein and turns the quick pasta into a meal that lasts until morning.
Drinks
Dry White Wine
A cool, dry white wine matches the chilli heat and lifts the garlic without competing with it.
Complete menu
Serve the spaghetti aglio e olio in warm bowls with a bitter-leaf salad, warm bread for the oil, and a glass of dry white wine.
Digestive Guardrails
To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:
Measure the Oil
A lot of oil makes the dish rich, so measure the oil rather than pouring freehand, and pair the pasta with a salad. This is general food information, not medical advice.
Do Not Burn the Garlic
Garlic that burns turns bitter and stays bitter — nothing in the pan fixes it, so keep the heat low and take the pan off the flame if the garlic colours too fast. This is general food information, not medical advice.
