Udon Soup Recipe

The first thing I notice when making this udon soup is how much character comes from a very short ingredient list. Dashi gives the broth a clean, savory depth, while the combination of 2 tablespoons each of soy sauce and mirin makes it balanced rather than simply salty. The mirin adds a gentle sweetness that rounds out the dashi, and the sliced kamaboko contributes a mild seafood flavor along with its pleasantly springy texture. It is a simple Japanese lunch, but the contrasting textures—silky noodles, chewy fish cake, crisp scallions, and bits of tempura—make every bowl feel complete. I like to prepare the tempura element first, using the cup of tempura batter to make small, irregular pieces rather than one large fritter. They can be fried until lightly golden and broken into bite-sized pieces, then added to each bowl just before serving. This gives the soup a little crunch at the start, followed by soft, savory crumbs as the batter absorbs the dashi. If you prefer a lighter finish, use only a small handful per serving; too much will make the broth cloudy and heavy. The scallions should be sliced thinly so their fresh, sharp flavor cuts through the richness of the tempura. The main technique that makes this udon successful is keeping the noodles and broth from overcooking together. Cook the 8 ounces of udon according to the package directions, then drain them well before adding them to the seasoned dashi. Meanwhile, warm the dashi with the soy sauce and mirin just until it is steaming; it does not need a long boil. A hard boil can flatten the delicate flavor of the dashi, and leaving the noodles in the pot too long can make them soft and gummy. I also rinse the cooked udon briefly if it is particularly starchy, then warm it in the broth for only a minute before serving. This soup is especially good for lunch on a cool day, when you want something satisfying without a long cooking project. It comes together in about 35 minutes and serves four comfortably, with the kamaboko and tempura making it more substantial than a plain noodle broth. Serve it with a small dish of pickled vegetables, cucumber sunomono, or steamed edamame. For a fuller meal, a few pieces of extra tempura or a simple rice ball pair nicely, though the soup is best enjoyed soon after assembling so the noodles stay springy and the tempura keeps some of its texture.
