What is Uni Pasta?

Uni pasta is a creamy, upscale pasta made with uni (sea urchin roe) characterized by a rich, buttery, aromatic, and umami flavor. It is a popular Japanese fusion pasta typically served in high-end restaurants. Other Japanese fusion pasta recipes include mentaiko pasta, spaghetti Napolitan (Japanese ketchup pasta), and miso carbonara udon.

Uni pasta is made with al-dente thin spaghetti noodles that are coated in a creamy pasta sauce made with sea urchin, heavy cream, sake, garlic, and shallots. You can find uni in the refrigerated aisle at your local Japanese grocery store.

Ingredients

You can find all the ingredients for this uni pasta recipe at your local Japanese grocery store. Full measurements and links to all the ingredients I used are listed in the recipe card below.

  • Thin Spaghetti: is ideal for absorbing the rich creamy, uni sauce.
  • Uni: or sea urchin has a rich and complex flavor that is salty, slightly sweet, and has a silky, melt-in-your-mouth texture.
  • Heavy Cream: is the rich and creamy base of the uni pasta sauce.
  • Unsalted Butter: adds a rich silky, flavor and creates a rich silky consistency for the uni sauce.
  • Garlic and Shallots: are the main savory, aromatic ingredients for the pasta sauce.
  • Salt and Pepper: seasons the sauce.
  • Sake: adds umami and natural sweetness. My go-to sake for cooking is Sho Chiku Bai, a regular drinking sake that doesn’t contain added salt.
  • Garnishes: lemon, uni, tobiko roe, nori strips, chives.

Expert Tips

  • Use high-quality uni. Uni is the star of the recipe. Be sure to use fresh, high-quality uni for the best flavor.
  • Remember to reserve pasta water. The pasta water is important for thinning out the sauce to achieve a silky creamy consistency in the uni pasta sauce. Mix in the pasta water one tablespoon at a time.
  • Combine the uni without heat. Uni is very delicate and can overheat quickly. Mixing the uni with the stove turned off will prevent it from overcooking.
  • Taste and adjust: Before serving, taste and adjust the sauce with salt, pepper, or pasta water if needed.

Storage Instructions

This uni pasta is best served immediately. You can store any leftovers in an airtight container in the refrigerator for up to 2 days.

Reheat: microwave the uni spaghetti covered in 20 second increments stirring in between until warm. Or gently reheat in a pan with a splash of water or cream to loosen the sauce over low heat.

Pairing Suggestions

This uni pasta can be served for lunch or dinner on its own or with the following pairing suggestions.

FAQ

Do you eat uni raw?

Yes, uni is typically served raw. In this uni pasta, the uni is only slightly warmed with the warm pasta and sauce to preserve its delicate flavor and texture. I recommend buying fresh uni from a trusted source before making this recipe.

What does uni taste like?

Uni has a very unique, slightly sweet, briny, rich, and complex flavor. It has a silky, creamy, melt-in-your-mouth texture that is comparable to egg yolks.

What kind of pasta should I use for uni pasta?

Thin spaghetti, spaghetti, linguine, or tagliolini are the most popular options. They are all good for holding onto the sauce without overwhelming it.
