Preheat the oven to 400°F (204°C) and prepare a rimmed baking sheet. Spread the kielbasa and potatoes onto the baking sheet; season with salt, parsley, and pepper.
Bake for 15 minutes, then mix everything on the pan together, spreading around the oil from the kielbasa.
Bake for another 10-15 minutes; allow the dish to cool some before serving.
Notes
Expert Tips:
The kielbasa releases oil as it bakes, so you don't need to add extra oil.
Cut the ingredients the same size to ensure they cook at the same rate.
