Preheat the oven to 400F (200C) and line a large baking sheet with parchment paper.
Wash, peel, and slice the carrots diagonally into even pieces.
In a large mixing bowl, toss the sliced carrots with olive oil, ground cumin, garlic powder, kosher salt, and black pepper until well coated.
Spread the carrots in a single layer on the prepared baking sheet, ensuring they do not overlap.
Roast in the preheated oven for 20 to 25 minutes, flipping the carrots halfway through, until they are fork-tender and the edges are crispy.
Remove from the oven, garnish with fresh parsley, and serve immediately.
