Japanese Autumn Soba Salad with Edamame

Peel the sweet potato and dice it into 3/4-inch cubes. Toss with a drizzle of sesame oil and a pinch of salt, then spread on a parchment-lined baking sheet. Roast at 400°F for 20-25 minutes, turning once, until caramelized on the edges and tender inside.

Bring a large pot of water to a rolling boil and add the soba noodles, stirring gently to prevent sticking. Cook for 4-5 minutes until just tender but still slightly firm. Drain and rinse thoroughly under cold running water to remove excess starch, then toss with a splash of sesame oil.

Add the shelled edamame to a pot of salted boiling water and cook for 3-4 minutes until bright green and tender. Drain and rinse briefly under cold water to preserve their vivid color and slight snap.

Slice the mushrooms into 1/4-inch pieces. Heat sesame oil in a skillet over medium-high heat and cook the mushrooms for 5-6 minutes, stirring occasionally, until golden brown and all moisture has evaporated. Season with a splash of soy sauce and set aside.

Remove the tough stems from the kale and slice the leaves into thin ribbons. Massage gently with a pinch of salt and a few drops of sesame oil for 1-2 minutes until slightly softened and darker green.

Combine soy sauce, freshly grated ginger, rice vinegar, and sesame oil in a small bowl and whisk vigorously until well blended. The dressing should be savory and aromatic with a bright vinegar tang.

In a large bowl, combine the chilled soba noodles, kale ribbons, roasted sweet potato, sautéed mushrooms, and blanched edamame. Pour the dressing over everything and toss thoroughly to coat each component evenly.

Divide the soba salad among bowls and top each with a generous sprinkle of toasted sesame seeds and thinly sliced scallions. Finish with a pinch of salt if needed and serve at room temperature or slightly chilled.
