We roast sunchokes (which sometimes are referred to as Jerusalem artichokes) with slices of red onion, then toss them with capers and dress them with a sour cream sauce containing tarragon and garlic.

Tip

Don’t forget to toss the just-roasted sunchokes and onions with the capers and lemon juice and let them stand for 10 minutes. The vegetables will absorb the lemon juice and cool just enough that the greens won’t wilt when they’re added.

Ingredients
  • 2

    pounds sunchokes, scrubbed but not peeled, cut into 1-inch chunks

  • 1

    medium red onion, halved and thinly sliced

  • 3

    tablespoons extra-virgin olive oil

  • Kosher salt and ground black pepper

  • ⅓

    cup sour cream OR plain whole-milk yogurt

  • 1

    medium garlic clove, finely grated

  • ¼

    cup lightly packed fresh tarragon, finely chopped

  • 4

    teaspoons lemon juice, divided

  • 2

    tablespoons drained capers

  • 2

    ounces (about 4 cups lightly packed) watercress OR baby arugula OR pea shoots

Step 1

Heat the oven to 450°F with a rack in the lowest position. In a large bowl, toss together the sunchokes, onion, oil and ½ teaspoon each salt and pepper.

Distribute in an even layer on a rimmed baking sheet; reserve the bowl. Roast, stirring once halfway through, until the vegetables are browned and a skewer inserted into the sunchokes meets no resistance, 25 to 35 minutes.

Step 2

Meanwhile, in a small bowl, whisk together the sour cream, garlic, tarragon, 2 teaspoons lemon juice and ½ teaspoon pepper. Taste and season with salt.

Step 3

When the vegetables are done, return them to the bowl. Add the capers and the remaining 2 teaspoons lemon juice; toss to combine, then let stand for about 10 minutes.

Toss in the greens. Transfer to a serving platter and drizzle with the sour cream mixture.
