Spaghettini
spah-geh-TEE-nee
Also known as thin spaghetti.
What it is
The name stacks two shrink-words onto one root: spago means string, spaghetto is a little string, and spaghettini is the thinner little strings. The shape sits one rung down the gauge ladder from spaghetti. Brands give it a thin-cut number close to the spaghetti number, De Cecco selling it as No. 11 against spaghetti at No. 12, and Garofalo cataloging it as No. 4. Both come from the durum heartland near Naples in southern Italy, where De Cecco ties spaghettini to that region directly. Because the strand runs thinner than spaghetti, cooks reach for it when they want a quicker boil and a lighter plate. The same dough and round strand carry over from spaghetti. Only the gauge changes, which is the point.
From Italian spaghetti plus the diminutive suffix -ini, marking a smaller, thinner version. Spaghetti itself is the plural of spaghetto, from spago, meaning cord, string, or twine, with the diminutive -etto. So the word stacks two diminutives onto a base that means little strings. Spaghettini reads as the thinner little strings.
What sauce it wants, and why
Spaghettini runs thinner than spaghetti, so it boils faster and asks for sauces that stay light. Heavy chunky ragu slides off the slim strand. Oil-based and brothy sauces coat it better. De Cecco points it at fresh tomato, vegetables, herbs, and quick olive-oil treatments with garlic, red pepper, and anchovy. Seafood and shellfish suit it well, and clam sauce is a brand-listed classic. Think aglio e olio, vongole, and a simple pomodoro rather than anything dense.
Classic plates: spaghettini alle vongole, spaghettini aglio e olio, spaghettini al pomodoro, spaghettini with shellfish and seafood sauces.

Easy to confuse with
Solid round strands graded only by thickness: capellini (finest), spaghettini, spaghetti, then spaghettoni (thickest), with vermicelli sitting near spaghetti. Bucatini looks like a thick spaghetti but has a hole running through the center.
