Preheat your oven to 400°F.

Spread the vegetables in a single layer on a rimmed baking sheet. Roast in the preheated oven for 40 minutes, stirring halfway through, until tender and lightly browned.
Remove the roasted vegetables from the oven. While still warm, toss them gently with softened butter and fresh thyme leaves. If using, sprinkle on Parmesan cheese. Transfer to a serving platter and serve immediately.
