01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Bring a large pot of salted water to a boil. Add carrots and cook for 10–12 minutes until tender but not mushy. Drain and let cool slightly.
03 - Place carrots on the prepared baking sheet. Use the bottom of a glass or jar to gently smash each carrot to about ½-inch thickness.
04 - Drizzle carrots with olive oil. Sprinkle with salt, black pepper, garlic powder, and smoked paprika. Toss gently to coat evenly.
05 - Roast in the oven for 20–25 minutes, flipping halfway through, until edges are crispy and golden brown.
06 - Transfer to a serving platter. Garnish with fresh parsley and Parmesan cheese if using. Serve warm.
