While most of the ingredients in this recipe are straightforward, you might need to visit an Asian supermarket to find somen noodles and mentsuyu.

These ingredients are essential for achieving the authentic taste of this dish.

Ingredients For Japanese Somen Noodle Recipe
Somen noodles: Thin, white Japanese noodles made from wheat flour, known for their delicate texture and quick cooking time.
Boiling water: Essential for cooking the somen noodles to the perfect consistency.
Mentsuyu: A savory Japanese dipping sauce made from soy sauce, mirin, sake, and dashi, providing a rich umami flavor.
Green onions: Chopped fresh to add a burst of color and a mild onion flavor to the dish.
Toasted sesame seeds: Adds a nutty flavor and a bit of crunch to the noodles.
Technique Tip for This Recipe
When preparing somen noodles, ensure you do not overcook them. Somen are very thin and cook quickly, so keep a close eye on the clock. Once cooked, immediately rinse the noodles under cold water to stop the cooking process and remove excess starch. This will help maintain their delicate texture and prevent them from becoming mushy.

How to Store or Freeze This Dish
Allow the somen noodles to cool completely before storing. This prevents condensation and sogginess.
Transfer the cooled noodles into an airtight container. If you have multiple servings, consider using separate containers to avoid clumping.
For added freshness, place a sheet of parchment paper between layers of noodles.
Store the container in the refrigerator. The noodles will stay fresh for up to 2-3 days.
When ready to eat, rinse the noodles under cold water to refresh them before serving with mentsuyu and toppings.
To freeze, first ensure the noodles are completely dry. Excess moisture can cause ice crystals and affect texture.
Portion the noodles into individual servings. This makes it easier to thaw only what you need.
Place each portion into a freezer-safe bag or container. Squeeze out as much air as possible to prevent freezer burn.
Label the bags with the date. Frozen noodles are best used within 1-2 months for optimal taste and texture.
To thaw, transfer the noodles to the refrigerator overnight. Alternatively, you can place the frozen noodles in a colander and run cold water over them until thawed.
Refresh the thawed noodles by rinsing under cold water before serving with mentsuyu, chopped green onions, and toasted sesame seeds.
How to Reheat Leftovers
- Gently reheat the somen noodles by placing them in a colander and dipping them into a pot of boiling water for about 30 seconds. This will help to refresh the noodles without making them mushy.
- Alternatively, you can microwave the somen noodles by placing them in a microwave-safe bowl, adding a splash of water, and covering with a microwave-safe lid or plastic wrap. Heat on medium power for 1-2 minutes, checking halfway through to ensure they are evenly warmed.
- For a more flavorful option, stir-fry the somen noodles in a pan with a bit of sesame oil and a splash of mentsuyu. Toss in some fresh green onions and toasted sesame seeds for added texture and taste.
- If you prefer a cold dish, simply rinse the somen noodles under cold water again to refresh them, and serve with chilled mentsuyu, green onions, and toasted sesame seeds.
