Ingredients

  • 1/2 pound winter squash
  • 1 pound Carnaroli or Arborio rice
  • 4 tablespoons butter, plus 2 tablespoons for greasing dish
  • 1 medium onion, diced, about 1 cup
  • 1 medium leek, white and tender green part, diced, about 1 cup
  • Pinch of saffron (optional)
  • Salt and pepper
  • 3 cups squash broth (see note) or chicken broth, hot
  • 8 ounces Gruyere or Fontina, grated, about 2 loosely packed cups
  • 1 cup fresh ricotta
  • 4 ounces Parmesan, grated, about 3/4 cup
  • 2 teaspoons lemon zest
  • 1 cup coarse dry bread crumbs
  • 3 tablespoons chopped parsley

Method

  • Peel squash and cut into very thin slices, 1/16-inch thick.
  • Then cut slices into flat 2-inch squares.
  • (Reserve the scraps, including peels, to make squash stock if desired.)
  • Bring a large pot of salted water to a boil.
  • Add rice and let simmer for 8 minutes so it is parcooked, with the grains still hard in the center.
  • Drain rice in a colander, rinse with cold water, then spread on a baking sheet to cool.
  • Heat oven to 375 degrees.
  • In a Dutch oven, melt 4 tablespoons butter over medium heat.
  • Add onion and cook, stirring, until softened, about 5 minutes.
  • Add leek and saffron, if using, and stir to coat.
  • When leek is softened but still green, after 2 minutes, add squash, stir to coat and turn off heat.
  • Season well with salt and pepper.
  • Add parcooked rice, hot broth, Gruyere, ricotta, Parmesan and lemon zest, mixing gently with a wooden spoon.
  • Pour rice mixture into a buttered 3-quart baking dish.
  • Sprinkle top with bread crumbs, pressing down to smooth surface.
  • Bake for 20 to 25 minutes.
  • Tent with foil if necessary.
  • Garnish with parsley just before serving.
