Adjust rack to top position and preheat oven to 425 degrees. Wash and dry produce.
Dice potatoes into 1⁄2-inch pieces. Place potatoes in a medium pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 15-20 minutes.
Reserve 1⁄2 cup potato cooking liquid, then drain. Return potatoes to pot. (You’ll finish the potatoes in Step 4.)
