Mentaiko Pasta

First posted in 2011, updated in Mar 2015.

Mentaiko is marinated pollock roe and a popular ingredient in Japanese cuisine. Using it to make mentaiko pasta (明太子パスタ) is my favourite way to enjoy this ingredient. This Italian-Japanese pasta is usually quite expensive on the menu, but easily less than half the price and more than double the roe, to make at home.

As gourmet as this pasta may sound and look, it is actual the simplest pasta recipe out there! The sauce does not require stove-top cooking and took me 5 minutes. The only real cooking I did was to cook the pasta (spaghetti).

Mentaiko Pasta Sauce Recipe

To make the 5-minute sauce, I basically melted butter in the microwave, then whisked in the other ingredients in a small bowl.

Karashi Mentaiko (辛子明太子)

There are two main types of spicy ‘karashi’ mentaiko (辛子明太子) you can find at the local Japanese supermarkets. The colourless type will result in a colourless pasta with visible bits of roe in it. On the other hand, the coloured type (featured in this recipe; pictured above), will result in a slight salmon pink pasta sauce.  Click here to read more information about mentaiko.

Mentaiko Pasta

Using colorless mentaiko will result in a pale pasta while using the coloured type will result in a pale salmon pink sauce. Be sure to buy the right type of mentaiko accordingly to your preference.

Ingredients:

  • 60 grams (or one small sac) spicy ‘karashi’ mentaiko sac (辛子明太子)
  • 1 serving (about 70 grams) spaghetti (or any favourite pasta)
  • sea salt to taste

(A) Mentaiko Sauce

  • 30 grams butter cubed and melted in the microwave
  • 1/4 tsp Japanese shoyu (light soy sauce) to taste
  • 2 tbsp Japanese mayonnaise
  • 2 tsp sake may subsitute with mirin

Topping Suggestion

  • 1 tsp mentaiko see step 1
  • shredded nori (roasted seaweed)
  • finely shredded baby shiso or finely chopped spring onions

Directions:

  1. Make a slit on the mentaiko sac and scrap out the roe with a spoon. Discard the membrane. Set aside 1 tsp of roe for garnishing.
  2. In a small bowl, add the fish roe along with (A). Whisk to combine everything together.
  3. Cook pasta in salted water until al dente (firm with a bite; usually shaving 2 minutes off recommended cooking time for spaghetti). Drain pasta and reserve a small cup of pasta water.
  4. Add the mentaiko sauce to the drained pasta while it is still hot. Toss until even. If the pasta is too dry, add a bit of reserved pasta water to help bind the ingredients together. Season to taste with salt if needed.
  5. Dish the pasta to a serving plate. Garnish with mentaiko, shredded nori and shiso or spring onions.

Noob Cook Tip

If you prefer a richer taste, you can add 1 tablespoon of cream (to taste) to the mentaiko sauce.
