Adjust racks to top and middle positions and preheat oven to 425 degrees. Wash and dry produce.
Dice potatoes into ½-inch pieces. Place 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 ½ cup potato cooking liquid, then drain.
Return potatoes to pot and cover to keep warm. (You’ll finish the potatoes in Step 4.)
