Saffron Risotto with Butternut Squash

Preheat the oven to 400 degrees. Peel the butternut squash, remove the seeds, and cut it into 3/4-inch cubes. You should have about 6 cups. Place the squash on a sheet pan and toss it with the olive oil, 1 teaspoon salt, and 1/2 teaspoon pepper. Roast for 25 to 30 minutes, tossing once, until very tender. Set aside. Meanwhile, heat the chicken stock in a small covered saucepan . Leave it on low heat to simmer. In a heavy-bottomed pot or Dutch oven , melt the butter and saute the pancetta and shallots on medium-low heat for 10 minutes, until the shallots are translucent but not browned. Add the rice and stir to coat the grains with butter. Add the wine and cook for 2 minutes. Add 2 full ladles of stock to the rice plus the saffron, 1 teaspoon salt, and 1/2 teaspoon pepper. Stir, and simmer until the stock is absorbed, 5 to 10 minutes. Continue to add the stock, 2 ladles at a time, stirring every few minutes. Each time, cook until the mixture seems a little dry, then add more stock. Continue until the rice is cooked through, but still al dente , about 30 minutes total. Off the heat, add the roasted squash cubes and Parmesan cheese . Mix well and serve.
