01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper.
02 - Place the carrots on the baking sheet. Drizzle with olive oil and season with salt, pepper, and cumin (if using). Toss to coat evenly and spread in a single layer.
03 - Roast for 25-30 minutes, turning once halfway, until the carrots are tender and caramelized around the edges.
04 - Remove from the oven and immediately drizzle with honey while the carrots are hot. Toss gently to coat.
05 - Transfer to a serving platter. Sprinkle with chopped pistachios and parsley, if desired. Serve warm.
