Spaghetti Aglio e Olio

To create a creamy sauce without using any cream, you must vigorously mix the garlic-infused olive oil with starchy pasta cooking water directly in the pan. The starch in the water binds with the fat, creating a thick, cohesive emulsion that coats the noodles. This technique relies on constant tossing off the heat just before serving.

Authentic Italian spaghetti aglio e olio relies on high-quality extra virgin olive oil as its primary fat and flavor base. Using a robust, peppery extra virgin olive oil will deeply enhance the overall flavor profile of the minimalist dish. Many traditional chefs also finish the dish with a splash of raw, high-quality oil right before serving.

Garlic burns very quickly, and once it darkens past a light golden brown, it becomes intensely bitter and will ruin the entire dish. To prevent this, the sliced or minced garlic must be cooked slowly over low to medium-low heat in the olive oil. You should remove the pan from the heat entirely as soon as the garlic is fragrant and barely turning golden.

No, authentic Italian spaghetti aglio e olio is traditionally served without grated Parmigiano-Reggiano or any other dairy cheese. The dish originates from central Italy and relies entirely on the emulsion of oil, garlic, chili, and pasta water for its richness. Adding cheese is generally frowned upon by traditional Italian culinary purists.
