What is Toshikoshi Soba?

Toshikoshi soba is a traditional Japanese noodle dish eaten on New Yearโ€™s Eve to mark the transition from one year to the next. The long buckwheat noodles symbolize longevity, resilience, and letting go of difficult times, making this simple bowl of noodles very meaningful in Japanese cuisine.

On the last day of the year, Japanese people focus on completing tasks such as cleaning their house, paying back debts, and bathing (cleansing the body), in order to start the new year fresh. These tasks are usually done early during the day so that people can gather and relax in the evening. A bowl of toshikoshi soba is served about an hour before ringing in the new year.

Ingredients for Toshikoshi Soba (New Year Soba)

Toshikoshi Soba Ingredients

  • Soba Noodles: There are many different types of soba noodles and the ratio of buckwheat to flour can vary greatly. If you like chewy noodles, I recommend looking for soba noodles that are a mix of 50/50 buckwheat flour and whole wheat flour. I personally love my noodles to be on the grainier side so I usually go for soba noodles that are as close to 100% buckwheat flour as I can find.
  • Soup: A mixture of water, soy sauce, dashi, sake, and mirin.
  • Eggs:ย Use medium or large eggs. I like to medium boil my eggs so that the yolk is creamy and the white is almost entirely solid. But please go ahead and cook your eggs however you like.
  • Scallions:ย Chopped scallions add a nice crunch and a little sweetness.
  • Wakame:ย Seaweed is a classic topping for noodle soups in Japan. It adds a mineral component and a little taste from the sea.
  • Naruto fish cakes:ย Called narutomaki in Japanese, these fish cakes are white with a pink swirl in the center. If you cannot find naruto fish cakes you can use any other type of kamaboko,ย which is a type of surimi, a processed seafood like crab sticks.

How to Make Toshikoshi Soba

  1. Prep the ingredients. Measure the ingredients and slice the scallions and fishcakes.
  2. Boil the eggs. Boil the eggs until they are medium boiled – about 6 minutes – and drain. Shock the eggs in an ice bath to prevent them from overcooking.
  3. Make the broth. Put all the ingredients for the broth in a pot and bring to a boil. Turn the heat to low, cover, and simmer for 10 minutes.
  4. Boil the soba noodles. Meanwhile, bring another pot of water to boil. Add the soba noodles and follow the cooking instructions on the package. Drain the noodles and divide them among two bowls.
  5. Assemble the dish. Add the broth to the noodles and top with eggs, fish cakes, scallions, and wakame. Serve immediately.

Toshikoshi Soba isnโ€™t just about food โ€” itโ€™s about reflection, gratitude, and starting fresh. Whether you stick to tradition or put your own spin on it, this bowl of noodles is a beautiful way to welcome a new year.

Recipe Tips

  • Soba noodles should be a little al dente โ€” buckwheat noodles should be tender but not mushy. It’s best to slightly undercook them so they don’t soften too quickly once added to the broth.
  • Keep the broth light, not too salty โ€” this dish is meant to feel cleansing.
  • Serve immediately โ€” before the noodles get too soft of soggy.

Frequently Asked Questions

Description

Toshikoshi soba is a traditional Japanese soba noodle dish served with a hot tsuyu broth and various toppings on New Year’s Eve.ย 


Ingredients

Scale
  • 2 large eggs
  • 6 ounces dry soba noodles
  • 2 tablespoons chopped scallions
  • 4 to 6 slices naruto fish cakes or other fish cakes
  • 2 teaspoons dry wakame seaweed

Broth (tsuyu)

  • 3 cups water
  • 4 tablespoons soy sauce, add more if needed
  • 3 teaspoons dashi powder
  • 2 tablespoons sake
  • 2 tablespoons mirin

Instructions

  1. Medium boil the eggs using an egg cooker, or place the eggs in a small pot and fill it with cold water, to just above the tops of the eggs. Bring the water to a boilย  and turn the heat off. Cover with a lid and let sit for 6 minutes. Drain and transfer the eggs to an ice bath. Leave for 5 minutes before peeling them. Set the peeled eggs aside.
  2. Add all the ingredients for the broth in a small pot and bring to a boil. Lower the heat to low, cover with a lid, and simmer for 10 minutes.
  3. Bring a separate pot of water to boil and cook the soba noodles according to the directions on the package.
  4. Drain the noodles and divide them among two serving bowls. Add the broth and top with eggs, scallions, fish cakes, and wakame. Serve immediately.

Notes

Prepping ahead of time: You can make the broth and keep it refrigerated until it’s time to use it. Chopping all the toppings ahead of time and storing them in the fridge in separate containers is also a big time saver.
