Spinach ohitashi is a classic Japanese side dish that turns simple blanched spinach into a light, refreshing salad with clean dashi flavor and bright sudachi aroma. The spinach is usually boiled briefly, cooled in water, and squeezed gently so it stays tender without becoming watery. It is then soaked or dressed with a mixture of dashi, soy sauce, mirin, and sometimes a little sugar to give the greens a delicate balance of umami, saltiness, and gentle sweetness. Sudachi juice adds a fresh citrus note that makes the dish taste brighter and more elegant without overpowering the spinach. Toppings like bonito flakes, sesame seeds, grated ginger, nori, or green onion can add extra aroma and texture. The final ohitashi is simple, healthy, and easy to serve with steamed rice, miso soup, grilled fish, karaage, noodles, bento boxes, or other Japanese home-style meals.
