Adjust rack to middle position and preheat oven to 450 degrees. Wash and dry produce.
Cut potatoes into ½-inch-thick wedges. Toss on a baking sheet with a large drizzle of oil, half the garlic powder (you’ll use the rest later), and a big pinch of salt and pepper.
Roast on middle rack until browned and tender, 20-25 minutes.
Trim and discard woody bottom ends from asparagus. Swap in asparagus for potatoes; roast until lightly browned and tender, 10-12 minutes. (Save potatoes for another use.)
