Uncover the pan and add the sugar, stirring well to combine. Continue to simmer, uncovered, stirring occasionally, until the liquid has evaporated and the carrots and squash are glazed, 5 to 6 minutes more.
Transfer the carrots and squash to a warmed serving bowl, sprinkle with the parsley and serve immediately.
