Cold Somen Noodles with Dipping Sauce
Chilled somen noodles served with an aromatically complex dipping sauce are a beloved fixture of Japanese summertime cuisine. Light, slippery, and endlessly customizable, this dish is both cooling and deeply satisfying—a perfect choice for sweltering days or fast weeknight meals.
What Are Somen Noodles?
Somen are extremely thin wheat noodles, usually less than 1.3 mm in diameter. Their delicacy and quick cooking time make them a favorite in the summer, especially when served cold.
Typically, somen noodles are sold dried and are ready in just a couple minutes in boiling water. They have a smooth texture and mild flavor, which makes them an ideal partner for robustly seasoned dipping sauces.
- Shape & Size: Very thin, pale wheat noodles
- Cooking Time: Often just 2 minutes
- Main Uses: Served chilled with dipping sauce, or sometimes in soups
Why Cold Somen Noodles?
Cold dishes are a staple of Japanese culinary tradition during hot weather. Somen, served on ice, provides instant relief from the heat. The noodles’ slippery texture and their pairing with savory sauce turn this simple meal into a ritual of rejuvenation.
As noted by expert cooks, cold somen is unusually refreshing and can be prepped with minimal heat—another key advantage when the stove is best left off.
Ingredients Breakdown
- Somen Noodles: 8 ounces dried somen for 4 servings
- Dipping Sauce (Tsuyu):
- 3 cups dashi broth (instant or homemade)
- 7 tablespoons light soy sauce
- 1 tablespoon mirin (optional for sweetness)
- 1 tablespoon sugar
- 1/2 cup bonito flakes (for deeper umami)
- Optional Toppings:
- Ice cubes
- Scallions, finely sliced
- Grated ginger
- Wasabi paste
- Thin omelet strips
- Shredded cucumber or other vegetables
Step-by-Step Recipe: Cold Somen Noodles with Dipping Sauce
1. Prepare the Dipping Sauce (Tsuyu)
- Combine dashi, soy sauce, mirin, and sugar in a small saucepan.
- Bring to a gentle boil, then turn off heat. Add bonito flakes (if using), steep for 2 minutes, and strain.
- Cool rapidly over an ice bath or refrigerate. The sauce should be very cold when served.
- Tip: Some cooks dissolve dashi powder directly in cold water for an ultra-fast version. The typical ratio is 80% dashi, 10-15% mirin, and 5-10% soy sauce, adjusted to taste.
2. Cook and Chill the Somen
- Boil water in a kettle or saucepan. Add somen noodles and cook for 2 minutes or until just tender.
- Drain immediately and rinse under ice-cold water until completely cool and slippery.
- Drain well. Some traditional mats help further air-dry noodles, but a regular strainer is sufficient.
- Form noodles into small bundles for easier dipping and an attractive presentation.
3. Arrange and Serve
- Place noodle bundles on a platter or bamboo mat, scattered with ice cubes.
- Provide a small bowl of chilled dipping sauce (tsuyu) on the side for each diner.
- Top noodles with scallions, ginger, wasabi, and vegetables as desired.
- To eat, diners use chopsticks to pick up noodles, swirl them briefly in the sauce, and enjoy each cold, savory bite.
Flavor and Texture: The Heart of Somen
Successful cold somen hinges on contrast. The noodles should be icy, springy, and delicate, while the sauce should deliver a punch of umami, salt, and gentle sweetness. Adjusting the proportions and chilling both noodles and sauce is key for maximum refreshment.
Key Tips for Optimal Flavor
- Always taste the sauce and tweak: it should be mostly savory, lightly salty, and just a touch sweet.
- Serve everything extremely cold—add ice cubes directly to both noodles and sauce if needed.
- Use fresh toppings for added aroma and snap.
Alternative Serving Suggestions
Somen noodles are endlessly versatile. Here are ways to customize and expand the dish:

Yes, the sauce (tsuyu) can be made up to two days ahead and kept in the refrigerator. Just ensure it is well chilled before serving.
Do I need a special mat for serving?
Traditional bamboo mats help water drain below the noodles, but any serving plate or strainer works well.
