I have something classy, deliciously savory yet simple enough for you to make this weekend and it’s Mentaiko Udon (明太子うどん)! Here, slippery udon noodles are coated in a buttery spicy cod roe mixture and accented with fresh Japanese herbs and shredded nori. Unlike any other noodle dishes you’ve tried before, mentaiko udon is truly special. You’ll need one or two Japanese ingredients but cooking it is easy enough.

What is Mentaiko Udon?

This mentaiko udon is a creative twist on the classic Mentaiko Pasta (Spicy Cod Roe Pasta), a Japanese-Italian fusion pasta dish made with preserved spicy cod, milk, cream, and spaghetti noodles. I learned that this particular pasta is not only very popular in Japan, but also in some major Asian cosmopolitan cities. Quite a few JOC readers told me that they have tried mentaiko pasta in some modern Japanese restaurants. Since udon is well suited to just about any flavor, it makes sense to pair it with the mentaiko sauce. The creamy, robust sauce clings to the plump strands of udon, the result is simply noodle perfection.

Why You’ll Love Mentaiko Udon

Quick and easy! It comes together in 15 minutes. It’s one of my go-to dishes when I don’t have time. I always keep at least two mentaiko packages in my freezer. Pantry-friendly. Besides mentaiko and shiso leaves, both of which are available at Japanese or Korean grocery stores, the ingredients for this recipe are simple enough that you can get them at regular supermarkets. A unique noodle dish that is packed with plenty of ‘wow’ factors. Think interplay of flavors and textures.

What is Mentaiko?

Mentaiko (明太子) is the chili-spiced salted roe of pollock or cod and is usually used as a filling for Onigiri (rice ball) or as a topping for noodle dishes. This Japanese delicacy offers an exciting mouthfeel with just the right amount of spice. You can find mentaiko in either the refrigerated or frozen section of Japanese or Korean supermarkets. It is not an easy ingredient to source, but I still hope you have a chance to try it. The only substitute for mentaiko is tarako (たらこ), the cod/pollock roe that’s not prepared with chili. Your young children would be able to enjoy tarako since it is not spicy.

Ingredients for Mentaiko Udon

Udon noodles – I recommend using only fresh or frozen udon noodles for this recipe. The thicker and chewier texture plays an important role in the success of the dish. Learn more about udon. Spicy salted pollock roe or cod roe (karashi mentaiko)  Squid – It’s optional, but it adds complexity and heft to the noodle dish. Onion Heavy whipping cream Soy sauce Butter – Butter has a sweet and rich creaminess, but you can use extra virgin olive oil to keep things lighter. Sake Salt & pepper Toppings: shiso leaves and shredded nori. They are optional but make a difference in elevating the flavor and presentation.
