Toshikoshi Soba

In Japan, the New Year is a significant family celebration, and one cherished tradition is eating a warm bowl of soba noodles on New Year’s Eve, known as Toshikoshi Soba (年越し蕎麦). The long, thin buckwheat noodles symbolize good health and a long life. We believe that eating these noodles at the end of the year helps “cut off” the misfortune of the past year and brings good luck and fortune to the family in the year ahead.

Recipe Ingredients

You’ll need the following ingredients to make this Toshikoshi Soba recipe:

Toshikoshi soba ingredients list.
  • Soba Noodles: Dried, fresh, or frozen noodles all work. Cooking times differ by type and brand, so check the package instructions. I use fresh buckwheat soba noodles in this recipe. Not sure which one to choose? Read my soba types guide here!
  • Toppings: There are many delicious topping options, but in this recipe, we use onsen tamago (soft-cooked egg), kamaboko fish cakes, tenkasu (crispy tempura flakes), wakame seaweed, and scallions. For more ideas, check the Toppings variations!
  • Noodle Soup: Japnaese noodle soup, known as mentusyu, is made with dashi, salt, mirin, and soy sauce. Dashi is the key to a rich, umami-packed broth, and I usually use dashi powder for convenience. For a plant-based option, try homemade kombu dashi or kombu dashi powder.

Soba Noodles

Soba noodles are traditional Japanese noodles made by kneading buckwheat flour (often mixed with regular wheat flour) with water, rolling out the dough, and cutting it into thin strips. They can be enjoyed cold with a dipping sauce or served in a hot dashi broth.

Recipe Tips

  • Rinse After Cooking:
    After boiling the noodles, drain and rinse them quickly under cold running water. This stops the cooking process and tightens the noodles, preventing them from becoming soft or mushy.
  • Stir Occasionally:
    To keep the noodles from sticking to the bottom of the pot, gently stir them with chopsticks from time to time while cooking.
  • Adjust the Soup Seasoning:
    If the noodle soup tastes too salty, dilute it with a small amount of water. If it’s too mild, add a little soy sauce or salt to tweak the flavor.
  • Make the broth ahead:
    Prepare the dashi stock in advance and reheat gently before serving.

Topping Variations

This is the fun part! Various ingredients go well with Toshikoshi soba. I have listed the classic and popular toppings that are easy to prepare.

Topping variations for toshikoshi soba.
  • Vegetables: Green onions, scallions, spring onions, spinach
  • Seaweed: Wakame Seaweed, tororo kombu (flakes of kombu seaweed)
  • Egg: Onsen tamago, raw egg, boiled egg
  • Other: Agedama (tenkasu, pieces of tempura batter), kamaboko fish cakes, aburaage (thin deep-fried tofu)
