This week’s Easy College Meal Series is the classic Japanese-fusion Mentaiko Pasta. It’s fancy and indulgent yet ridiculously easy to make. If you have a Dezin Electric Cooker, both cooking and cleaning time will be cut in half. As I always tell my son, “There’s no excuse not to cook and eat well, even if you live in a dorm or are too busy with exams.”

Now, let us show you how you, too, can make this special pasta dish in just 10 minutes!

What to Know about Mentaiko Pasta

Mentaiko Pasta (明太子パスタ) is a beloved Japanese fusion dish that combines the best of both worlds: the comforting familiarity of Italian pasta with the rich, briny flavors of mentaiko—spicy salted cod roe.

This simple yet decadent wafu pasta (和風パスタ) became popular in Japan in the 1970s and has since become a staple in both home kitchens and restaurants. Known for its creamy, umami-packed sauce, mentaiko pasta delivers a satisfying kick from the mentaiko, balanced by the richness of butter or cream. It’s also quick to make, deeply flavorful, and the perfect example of how Japan effortlessly blends global cuisines into something truly unique.

You can find my original Mentaiko Pasta recipe where you can cook the pasta separately for two or more servings in the pot.

Ingredients You’ll Need

Where to Buy Mentaiko

You can find (karashi) mentaiko (辛子明太子) in either the refrigerated or frozen section of Japanese or Korean supermarkets. When planning a trip to a Japanese or Korean grocery store, it’s the perfect time to stock up on the special ingredients you need for making Japanese dishes.

Karashi Mentaiko (Spicy Pollack/Cod Roe)

Alternatively, you can order mentaiko imported from Japan from this online seafood shop offers. The Japanese food company S&B carries an instant mentaiko spaghetti sauce which is available on Amazon. You can use the instant sauce but it will not be the same.

Substitution Tips

Milk and Heavy Whipping Cream: You can use “Half and Half” instead of mixing milk and heavy whipping cream. Prefer a lighter sauce? Use whole milk (or reduced-fat milk) only. You can use heavy cream only for a creamier consistency.

Butter: You can replace the butter with extra virgin olive oil.

Shiso (perilla leaves): This Japanese herb adds a fresh and herbaceous element and a lovely aroma to the creamy and savory pasta. You can buy it at a Japanese/Korean grocery store. If you can’t find it, then you can leave it out. There’s no good substitute for shiso.

If you’re adventurous, you can try a tiny bit of mint or basil, or a mix of herbs of your choice, to add a touch of freshness. Please let us know what you experimented with and how it worked.

How To Make One-Pot Mentaiko Pasta

  1. Prep the ingredients. This dish comes together really quickly, so make sure the table is set, and you’re ready to dig in!
  2. Start boiling the water, then add the salt and spaghetti! This takes the longest (10 minutes).
  3. Drain the pasta water from the pot.
  4. Toss the pasta, ingredients, and seasonings in the pot.
  5. Transfer the pasta to a plate, and top with shiso and nori seaweed. Serve immediately!

Recipe Tips

  • Salt the pasta water once it starts boiling. The salted water will help season your spaghetti.
  • You don’t need to break the spaghetti in half if you have a pot large enough to fit the noodles. Here, we cook a single serving in a small Dezin Electric Cooker, so we have to break the pasta to make sure it cooks evenly and remains al dente.
  • When draining the pasta cooking water, use the pot’s lid to keep the spaghetti from falling out. This is convenient if you don’t have a sieve on hand!
  • Adjust the ratio of the butter, milk, and cream to achieve your preferred creaminess.
  • Cook only the portion you need and enjoy it right away. I don’t recommend keeping leftovers, as mentaiko does not reheat well.

How To Store

If you reheat mentaiko, the fish eggs will overcook, so I do not recommend storing and reheating the pasta.

What To Serve with Mentaiko Pasta

You can put together a simple salad by tossing spring mix with any of these easy dressings to pair with the pasta.

  • When boiling, add ¼ tsp Diamond Crystal kosher salt. Break 4 oz spaghetti in half (so that it fits in the pot) and add to the boiling water. Tip: You don't need to break the spaghetti in half if you're using a big enough pot that fits the noodles.
