Risotto with Butternut Squash, Leeks, and Basil

This is a long over due recipe. I made it right after Thanksgiving and I didn't get a chance to post until now. I made turkey stock with my left over Thanksgiving turkey and also saved some of the turkey meat. I used the turkey stock in place of the vegetable broth and also added some of the turkey meat. We ordered the smoke turkey from Greenberg Smoked Turkey. I loved that the turkey stock and the meat give the risotto a smoky flavor.

Ingredients:
3 tablespoons olive oil, divided
4 cups 1/2-inch cubes peeled butternut squash (from 2 1/4 pounds squash)
3 cups 1/2-inch-wide slices leeks (white and pale green parts only)
1 tablespoon chopped fresh thyme
2 cups arborio rice
4 14-ounce cans (or more) vegetable broth
1 cup chopped fresh basil
3/4 cup freshly grated Parmesan cheese plus additional (for serving)

Direction: 
1. Heat 2 tablespoons oil in heavy large pot over medium-high heat. Add squash and sauté until beginning to soften and brown around edges, about 5 minutes. Transfer squash to medium bowl.
2. Reduce heat to medium; add remaining 1 tablespoon oil, leeks, and thyme to same pot and stir until tender but not brown, about 5 minutes. Add rice and stir 1 minute. Add 1 cup broth and simmer until absorbed, stirring frequently, 3 to 4 minutes. Add remaining broth by 1/2 cupfuls, allowing each addition to be absorbed before adding next, stirring often, about 15 minutes. Return squash to pot. Continue to cook until rice is just tender but still very creamy, stirring gently and often, about 10 minutes longer (about 25 minutes total cooking time). Remove from heat. Stir in basil and 3/4 cup freshly grated Parmesan cheese. Season to taste with salt and pepper. Transfer to large bowl and serve with additional Parmesan cheese.
