Ingredients

  • Rockfish fillet
    3/4 pound, divided into 2 portions $8.99
  • Organic delicata squash
    1 pound $1.66
  • Cosmic Crisp apple
    1 large, about 1/2 pound $2.59
  • Fresh sage
    1 tablespoon finely chopped leaves $2.49
  • Lemon
    1, yielding 1 teaspoon zest and 2 tablespoons juice $0.89
  • Olive oil
    2 tablespoons
  • Fine sea salt
    1 3/4 teaspoons
  • Ground black pepper
    1/4 teaspoon

Instructions

  1. Heat the oven to 425°F with a rack in the middle. Line a large rimmed sheet pan with parchment. Scrub 1 pound delicata squash, halve it lengthwise, scoop out the seeds, and slice into 1/2-inch half-moons; leave the edible skin on.

  2. Pat dry 3/4 pound rockfish fillet, check for pin bones, and divide into 2 portions. Season evenly with 3/4 teaspoon fine sea salt and refrigerate while the squash begins roasting.

  3. Toss the squash on the prepared pan with 1 tablespoon olive oil and 3/4 teaspoon fine sea salt. Spread into a single layer and roast for 20 minutes, turning once halfway through.

  4. While the squash roasts, core 1 large Cosmic Crisp apple, about 1/2 pound, and cut into 1/2-inch wedges. Zest and juice 1 lemon, measuring out 1 teaspoon zest and 2 tablespoons juice. Finely chop enough fresh sage leaves to make 1 tablespoon.

  5. Stir together the following to make a sage-lemon oil:

    • 1 tablespoon olive oil
    • 1 tablespoon finely chopped sage
    • 1 teaspoon lemon zest
    • 1/4 teaspoon ground black pepper

    Keep the lemon juice separate for finishing.

  6. Toss the apple wedges with 1 teaspoon of the sage-lemon oil and 1/4 teaspoon fine sea salt. Add them to the squash, leaving two clear spaces for the fish. Place the seasoned rockfish in those spaces and spoon the rest of the sage-lemon oil over it.

  7. Return the pan to the oven for 10–12 minutes, until the squash is tender, the apple has softened, and the fish reaches 140°F at its thickest point. Rest the fish on the pan for 2 minutes.

  8. Divide the roasted squash and apple between two plates and nestle a portion of rockfish alongside each. Drizzle the reserved 2 tablespoons lemon juice over the fish and vegetables, and serve.
