Udon Dipping Sauce Recipe: A Flavorful, Umami-Packed Cold Broth
When it comes to enjoying cold udon noodles, the dipping sauce plays a crucial role in bringing out their delicate chewiness and subtle wheat flavor. This udon dipping sauce recipe is the perfect balance of umami, sweetness, and spice, making every bite deeply satisfying.
Known as tsuketsuyu in Japanese cuisine, this cold udon dipping sauce is made by simmering a combination of miso, dashi, soy sauce, mirin, and aromatic seasonings like garlic, ginger, and shallots. After chilling overnight, the sauce develops an even richer depth, making it the perfect companion for cold udon with dipping sauce.
What Is Udon Dipping Sauce?
Udon dipping sauce, or tsuketsuyu, is a concentrated broth designed for dipping cold udon noodles. Unlike hot udon soup, which is served with noodles submerged in broth, this dipping sauce is served separately. The idea is to briefly dip the noodles before slurping them up, allowing the sauce to coat the noodles without overpowering their naturally mild flavor.
Traditional cold udon dipping sauce recipes often use a base of dashi, soy sauce, and mirin. This version takes it a step further by adding red miso for an extra layer of depth and a slight sweetness. The addition of caramelized shallots, garlic, and ginger enhances the umami richness, making this dipping sauce incredibly complex yet easy to prepare.

Each ingredient in this recipe plays a role in creating a balanced and flavorful dipping broth. Here’s a closer look at what makes this sauce so special:
- Dashi – The foundation of many Japanese sauces and soups, dashi provides a light yet savory umami flavor.
- Red Miso Paste – Aged longer than white miso, red miso has a bolder, more intense umami taste.
- Soy Sauce – Adds saltiness and enhances the depth of the sauce.
- Mirin – A slightly sweet rice wine that balances the saltiness and adds a hint of complexity.
- Garlic & Ginger – These aromatics bring warmth and a subtle spicy note to the sauce.
- Shallots – Caramelized shallots add a rich sweetness, making the sauce even more flavorful.
- Japanese Red Pepper (Ichimi Togarashi) – A touch of spice gives this cold udon dipping sauce a gentle heat.

How to Make Cold Udon Dipping Sauce
Now that we know the key ingredients, let’s go step by step through how to make cold udon dipping sauce at home.
Step 1: Caramelize the Aromatics
Heat oil in a saucepan over medium-high heat. Add the shallots, garlic, and ginger, stirring until they start to sizzle. Reduce the heat to medium-low and let them caramelize slowly. This step develops a deep, sweet-savory base for the sauce.
Step 2: Incorporate the Miso
Add the red miso paste to the pan, stirring to coat the caramelized aromatics. Allow it to cook briefly, deepening the flavor through caramelization.
Step 3: Simmer the Sauce
Slowly pour in the dashi, whisking to dissolve the miso completely. Let the mixture simmer for 5 to 10 minutes, allowing the flavors to meld.
Step 4: Season the Sauce
Add the soy sauce, mirin, sesame oil, and Japanese red pepper. Stir and let the sauce cook for another couple of minutes to incorporate the seasonings fully.
Step 5: Finish and Chill
Remove the sauce from heat and stir in chopped scallions and sesame seeds. Transfer to an airtight container and refrigerate overnight. This resting period enhances the depth of flavor, making the sauce even more delicious.
