Add oil and 2 teaspoons salt; toss to coat, then spread in a single layer. Roast until pumpkin is tender when pierced with the tip of a sharp knife, about 30 minutes, rotating pan and tossing vegetables halfway through. Let cool, then remove skins.
Transfer vegetables to a medium saucepan; heat over medium. Pour in 2 cups stock; puree with an immersion blender until smooth.
