Penne with Roasted Butternut Squash

1. Preheat the oven to 425°F.

2. Toss the squash cubes in a bowl with 1 tablespoon of the oil and 1/2 teaspoon of the salt (if using) and mix well. Spread onto a baking pan in a single layer and roast for 20 to 30 minutes until soft. Increase the oven temperature to broil and broil the squash for 2 minutes more.

3. When the squash is almost done, bring a large pot of water to a boil over high heat. Add 1 tablespoon of the salt (if using) and the penne and cook according to the package instructions until al dente. Reserve 1/3 cup of the cooking water and drain the pasta.
