Capellini vs Angel Hair Pasta Differences

Capellini vs. Angel Hair Pasta: What is the difference?

The primary difference between capellini and angel hair pasta comes down to their diameter. Capellini, which means “little hairs” in Italian is .85 to .92 millimeters while angel hair pasta measures .78 to .88 millimeters in diameter. Capellini is best suited to lighter sauces, such as olive oil or tomato sauces. Angel hair pasta is also suited for light sauces. Despite their very slight size differences, both kinds of pasta can be used interchangeably in most recipes.

The Italian word “capellini,” translates to “little hairs” in English. This is fitting for this very thin style of pasta, that does look a lot like spaghetti. Thin noodles like capellini and angel hair pasta, along with vermicelli rice noodles, all tend to cook very quickly in water. This makes them an easy dish to whip together, but also tends to mean they get overcooked!

Angel hair pasta, on the other hand, is called “capelli d’angelo” in Italy. It is the even thinner counterpart to capellini. These angel-hair-thin strands can provide a light and lovely glutenous base to marinara, cream, or pesto sauces. You can add it to seafood soups or mussels for a nice pairing with saltier ingredients.

The History And Origins 

If you guessed that both these kinds of pasta had their start in Italy, then you would be right! Recorded as far back as the 17th century, it was made in large sheets from an egg-based dough. These sheets were cut into tiny, tiny strips that were then rolled to create the shape of the pasta. According to Taste, Italian nuns would feed these pasta types to new mothers or people who were sick. Because of the texture when cooked, it was an easy meal to get down!

Eventually, these pastas made their way to the States with the help of Italian immigrants. There is a theory that it was such a hit because the translation of “Angel Hair” made the pasta sounds simply so beautiful! Flash forward to the 1990s, this pasta had a spike in popularity as a diet food! There were many ways to prepare the dish with a light sauce and since it digested so easily and filled you up, people were totally hooked!

How These Pastas Are Made

Traditionally, both these kinds of pasta would be cut and hand-rolled from a sheet of egg-based dough. They would then be hung to dry and coiled into nest-like clusters for eventual boiling. It was likely harder to differentiate capellini vs. angel hair when they were being hand rolled! Modern-day pasta machines allow for down to the micro-meter measurements of the diameter! All you need to do is set the numbers and it will cut the pasta accordingly.

Handmade capellini or angel hair pasta, has the same process as other pasta types. Add eggs to flour, and knead it into a dough with your hands. Refrigerate the dough until it is ready to be rolled out, and then, like the ancient Italian cooks, cut the pieces and roll them as thinly as you can. They may not look exactly like the storebought kind but how cool to try and make your own!

Taste recommends that the pasta is removed from the water right when it becomes “al dente.” This means that it still has some firmness and isn't totally floppy. Capellini and angel hair can both become overcooked fast and the result can be a glutenous, mushy mass of noodles. They're delicate and need to be cooked with that in mind!
