RECIPE: Spinach Ohitashi (Spinach Steeped in Dashi)


Ohitashi is a Japanese cooking method that involves blanching vegetables in hot water, then steeping them in a dashi-based sauce. The short cooking time preserves the freshness and texture of the vegetable, while the lightly smoky dashi highlights its natural flavor. In this recipe for spinach ohitashi, we combine flavors from the earth and sea for a simple, healthy, and refined side dish.

To make spinach ohitashi, start by preparing your spinach. Wash it thoroughly and make cross-shaped cuts at the base of each stem. Next, place the spinach in salted boiling water stem-side first. Since the stems are thicker, they take longer to cook and should be submerged before the leaves. Boil for 1-2 minutes, then remove and plunge into an ice bath to halt the cooking process. At this stage, the spinach should be tender, but not mushy. Gather the spinach by its roots and wring out the excess water, then slice it into bite-sized pieces. To add textural contrast to the dish, cut the stem and leafy parts into separate sections. 

Next, season the spinach. Pour ⅓ of the dashi and soy sauce mixture over the cut spinach, then wring it out once more. This infuses flavor into the spinach while ensuring it doesn’t get soggy. Then, pour the rest of the dashi and soy sauce mixture over the spinach and let it marinate for at least one hour. When you’re ready to serve, finish by garnishing with katsuobushi (bonito flakes). Spinach ohitashi can be prepared ahead of time and stored in the fridge for up to three days.
