Lotus Root Salad (れんこんサラダ, Renkon Sarada) is a refreshing and nutritious Japanese side dish that highlights the crisp texture and mildly sweet flavor of lotus root. Thinly sliced lotus root is lightly cooked until tender-crisp, then tossed with fresh vegetables and a creamy sesame or Japanese mayonnaise dressing. The result is a colorful salad with a delightful balance of crunchy textures, savory flavors, and subtle sweetness.

A staple in Japanese home cooking, lunch boxes (bento), and izakaya restaurants, Lotus Root Salad is especially popular during autumn and winter when lotus root is in season. In Japanese culture, lotus root symbolizes a bright future because its natural holes allow one to "see ahead," making it a traditional ingredient during New Year's celebrations and other festive occasions.

Easy to prepare and full of vitamins, fiber, and minerals, Lotus Root Salad is a delicious accompaniment to grilled fish, rice dishes, and hot pots.

Step 1: Prepare the Lotus Root

Peel the lotus root using a vegetable peeler.

Do not overcook.

Immediately transfer the slices to ice water to stop the cooking process and preserve their crunchy texture.

Drain thoroughly.

Step 3: Prepare the Vegetables

Julienne the carrot.

Thinly slice the cucumber.

Cook the edamame if needed and remove the beans from their pods.

Mix until smooth and creamy.
