Roasted Potato and Mushroom Salad

Roasting the potatoes and mushrooms deepens the flavor of this warm salad, and the mascarpone dressing adds richness and tang.Serves 6 to 8.

6 Tbs. extra-virgin olive oil

2 lb. Yukon gold potatoes (about 6 medium), halved and cut into 3/4-inch wedges

Kosher salt and freshly ground black pepper

3/4 lb. small to medium cremini or white mushrooms, quartered

1/2 cup mascarpone

1/4 cup fresh orange juice

1-1/2 tsp. red wine vinegar

1/3 cup thinly sliced scallions, white and green parts (about 4 small)

Position a rack in the center of the oven and heat the oven to 450°F. Coat a large rimmed baking sheet with 1 Tbs. of the oil.

In a large bowl, toss the potatoes, 2 Tbs. of the oil, 1 tsp. salt, and 1/2 tsp. pepper. Arrange in a single layer on the prepared baking sheet. Roast until barely tender, about 20 minutes, gently tossing with a spatula halfway through.

Meanwhile, toss the mushrooms, 1 Tbs. of the oil, 1/2 tsp. salt, and 1/4 tsp. pepper in the bowl.

Gently toss the potatoes again, scatter the mushrooms evenly over the potatoes, and continue to roast until both the potatoes and mushrooms are tender and golden brown in spots, 10 to 15 minutes more.

Meanwhile, in a medium bowl, whisk the mascarpone, orange juice, vinegar, 1 tsp. salt, and 1/8 tsp. pepper. Drizzle in the remaining 2 Tbs. oil while whisking constantly; set aside.

Return the potatoes and mushrooms to the large bowl and add the mascarpone dressing. Toss gently to coat, season to taste with salt and pepper, and transfer to a large serving bowl. Garnish with the scallions and serve.
