Acorn Squash Purée
Makes 4 cups; Prep time: 15 minutes; Total time: 1 hour 30 minutes
Prepare Basic Acorn Squash. When cool enough to handle, halve each squash lengthwise. Scoop out and discard seeds; scrape out flesh from squash halves, and transfer to a food processor (discard skin). Process until smooth. You can also season it and serve it as a side dish.
In a medium saucepan, combine squash purée with 2 tablespoons butter and 1 teaspoon coarse salt. Cook over medium heat until hot, 3 to 4 minutes. Transfer to a serving dish, and sprinkle lightly with ground nutmeg.
Lasagna
Preheat oven to 400°. Brush an 8-inch square baking dish with oil; set aside. In a medium bowl, mix squash purée with sage, 1 ½ teaspoons salt, and ¼ teaspoon pepper. In another bowl, mix ricotta with ½ cup Parmesan, 1 teaspoon salt, and ¼ teaspoon pepper. Set aside.
Lay 2 lasagna noodles in the bottom of prepared dish; spread with half the squash mixture. Layer with 2 more noodles, and spread with half the ricotta mixture. Repeat layering with remaining noodles and mixtures. Sprinkle top (ricotta mixture) with remaining ½ cup Parmesan.
Cover baking dish with foil; place on a rimmed baking sheet. Bake until lasagna is heated through, about 45 minutes; remove foil, and continue baking until golden on top, 20 to 25 minutes more.
