Sumashijiru (Clear Soup) with Tofu and Onion
すまし汁(豆腐・玉ねぎ) · Sumashijiru
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Sumashijiru is the clear, dashi-based soup you find alongside rice in a Japanese meal; unlike miso soup, it is seasoned only with a little soy sauce and salt, so the flavor of the dashi comes through. Here the onion is simmered slowly until it turns soft and sweet, and cubes of silken tofu are added at the very end so they stay tender. The mild, gentle taste makes it an easy soup for even the youngest children at preschool, and it pairs well with almost any main dish.
Wheat-free, but uses soy sauce (made with wheat). Japanese school-lunch allergy menus usually allow it, so check with your doctor. How to read the labels
