01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper.
02 - Cut carrots in half lengthwise if thick. Place on the baking sheet, drizzle with olive oil, and toss with salt and pepper. Spread in an even layer.
03 - Roast for 25-30 minutes, turning once halfway through, until carrots are golden and tender with caramelized edges.
04 - While carrots roast, whisk together tahini, lemon juice, garlic, water, parsley, dill, mint, cumin, and salt in a small bowl. Add more water, 1 teaspoon at a time, if needed for a smooth, pourable consistency.
05 - Transfer roasted carrots to a serving platter. Drizzle generously with the tahini herb sauce. Sprinkle with lemon zest and extra herbs if desired. Serve warm or at room temperature.
