In a large sauté pan, heat oil over medium-high heat. Add butternut squash and ½ teaspoon salt; cook, stirring occasionally, until golden brown and tender, about 15 minutes. Remove from pan and set aside.
In the same pan, melt butter over medium high heat. Cook, stirring frequently, until butter is lightly browned and toasted, 5 to 7 minutes. Add garlic, thyme, remaining 1½ teaspoons salt, and red pepper; cook until garlic is tender and lightly toasted, about 2 minutes. Return squash to pan. Add parsley and pasta, tossing to coat.
Top each serving with Parmesan. Garnish with parsley and thyme, if desired.
