BUTTERNUT SQUASH, COLLARD GREEN, AND WILD RICE GRATIN

Steps:

• 1. Put the wild rice in a medium saucepan with 3 cups water, 1 tablespoon olive oil, and a large pinch of salt. Cover and bring to a boil over high heat. Reduce the heat to medium-low and simmer until the rice is tender and has absorbed all the water, about 45 minutes. 2. Meanwhile, heat the oven to 425°F. Separate the head of garlic into cloves and peel each clove. Toss the garlic and butternut squash with 2 tablespoons of the olive oil and a little salt and pepper on a 13- by 18-inch baking sheet (or two smaller baking sheets). Roast, turning once or twice, until the squash is fully tender, 30 to 40 minutes. Remove, and reduce the oven temperature to 400°F. 3. While the rice and squash are cooking, remove the thick stems and ribs from the collard greens and discard them; cut the leaves into ribbons. Put the greens in a steamer over 1 inch of salted water in a large pot; cover the pot, bring the water to a boil, and steam the greens until tender, about 10 minutes. 4. Grease a 9- by 13-inch pan. Stir about half the Gruyere into the rice; spread the rice mixture into the pan. Arrange the collard greens on top of the rice and drizzle them with the remaining 1 tablespoon olive oil. Layer the squash and garlic on top of the greens, and gently mash them into the greens and rice with a potato masher or fork. Sprinkle the remaining Gruyere and the hazelnuts on top of the squash, and bake the gratin at 400°F until the cheese is melted and golden brown, 20 to 25 minutes. Serve hot or warm. (Store leftover gratin covered with foil or plastic wrap in the refrigerator for up to a few days.)
