Ingredients

  • Kosher salt
  • 1 head escarole, coarsely chopped
  • 1 head garlic, cloves separated but not peeled
  • 6 tablespoons butter
  • 10 to 12 fresh sage leaves, torn
  • 1 pound butternut squash, peeled and cut into bite-size pieces
  • Freshly ground pepper
  • 1 1/2 cups chicken stock
  • 3 tablespoons all-purpose flour
  • 3 cups milk
  • Freshly grated nutmeg
  • Two 15-ounce cans pure pumpkin puree
  • 3 eggs
  • 2 cups fresh ricotta
  • 2 cups freshly grated Parmigiano-Reggiano
  • 1 box no-boil flat lasagna
  • 12 ounces Italian Fontina, Fontina Val D'Aosta or Gouda cheese, shredded

Method

  • Preheat the oven to 375 degrees F.
  • Bring a few inches water to a boil in a large pot and add salt.
  • Cook the escarole for 5 minutes, then drain.
  • Cover the garlic cloves with water in a saucepan and simmer for 20 minutes.
  • Drain and let cool.
  • Squish the garlic pulp from the jackets into a bowl and mash with a fork.
  • Meanwhile, melt 3 tablespoons butter in a medium saucepan over medium heat.
  • Add the sage and stir.
  • Add the squash, stir and season with salt and pepper.
  • Add the chicken stock and cook, stirring occasionally, for 15 minutes.
  • All the stock should be absorbed and the squash should be lightly browned and tender.
  • Remove from the heat.
  • Melt the remaining 3 tablespoons butter in another medium saucepan over medium heat.
  • Add the flour and whisk for 1 minute.
  • Whisk in the milk and mashed garlic and season with salt, pepper and a little nutmeg.
  • Cook until slightly thickened (the sauce should just coat the back of the spoon evenly without breaking up on the spoon's surface).
  • Whisk together the pumpkin puree, 2 eggs and some salt and pepper in a small bowl.
  • In another bowl, whisk together the ricotta, half the Parmigiano-Reggiano and the remaining egg.
  • Preheat the oven to 375 degrees F. Soak the lasagna sheets in water for 5 minutes.
  • Pour about half the garlic sauce into the bottom of a 9 by 11-inch baking dish.
  • Add a layer of lasagna sheets and then half the pumpkin mixture.
  • Make another layer of lasagna sheets and spread with all of the ricotta mixture, followed by the squash and then escarole.
  • Top with half the Fontina, another layer of lasagna sheets, the remaining pumpkin and another layer of lasagna sheets.
  • Finish with the remaining garlic sauce and sprinkle with the remaining Parmigiano-Reggiano and Fontina.
  • Bake the lasagna, covered, for 45 minutes.
  • Raise the oven temperature to 400 degrees F and continue to bake, uncovered, for 15 minutes more.
  • Let rest for 15 minutes, then cut and serve.
