How to Use Japanese Komatsuna

Komatsuna is versatile and can be cooked quickly. Rinse well before use, separate thicker stems from the leaves if needed, then cook according to the dish.

• Stir-fry with garlic, ginger and light soy sauce
• Add to miso soup, clear soup or noodle soup
• Use in hotpot, shabu-shabu or steamboat
• Blanch and dress with sesame sauce or ponzu
• Use young leaves in salads and spring rolls
• Add to fried rice, omelettes or bento dishes
• Cook with mushrooms, tofu, chicken, pork or seafood

Simple Komatsuna Stir-Fry

For a quick stir-fry, cut the stems and leaves into bite-sized pieces. Stir-fry garlic and ginger first, add the stems, then add the leaves near the end.

Season lightly with soy sauce, oyster sauce, sesame oil, white pepper or mushroom sauce. Avoid overcooking, as the leaves can become too soft and the flavour may turn more bitter.

Komatsuna Soup and Noodle Ideas

Komatsuna works well in soups because the leaves soften quickly while the stems keep a nice bite. It can be added to miso soup, clear chicken soup, fishball soup, ramen, udon, soba, bee hoon soup or hotpot.
