Ingredients

1 1/2 pounds butternut squash, delicata squash, or sugar pumpkin-peeled, seeded, and cut into 1-inch pieces

5 tablespoons olive oil

kosher salt and black pepper

1/2 cup hazelnuts

1 tablespoon sherry vinegar or red wine vinegar

1 teaspoon Dijon mustard

6 cups mixed greens (about 4 1/2 ounces)

1/2 small red onion, thinly sliced

4 ounces blue cheese, crumbled (1 cup)

Preparation

  1. Heat oven to 400° F. On a rimmed baking sheet, toss the squash with 2 tablespoons of the oil, ½ teaspoon salt, and ¼ teaspoon pepper. Roast, tossing once, until golden brown and tender, 30 to 35 minutes. Let cool slightly.

  2. Meanwhile, spread the hazelnuts on a second rimmed baking sheet and toast in oven, tossing occasionally, until fragrant, 10 to 12 minutes. Let cool slightly, then rub in a clean dish towel to remove the skins (discard skins). Roughly chop.

  3. In a large bowl, whisk together the vinegar, mustard, the remaining 3 tablespoons of oil, and ¼ teaspoon each salt and pepper. Add the squash, hazelnuts, greens, and onion and toss to combine. Sprinkle with the blue cheese.
