01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper.
02 - Place carrots on the prepared baking sheet. Drizzle with 2 tbsp olive oil, sprinkle with kosher salt and black pepper. Toss to coat evenly.
03 - Arrange carrots in a single layer, cut side down. Roast for 25–30 minutes, flipping halfway through, until golden and tender.
04 - While carrots roast, combine parsley, dill, chives, lemon zest, pistachios, garlic, red pepper flakes, and flaky sea salt in a small bowl. Add 1 tbsp olive oil and mix to create a loose, crunchy topping.
05 - Transfer roasted carrots to a serving platter. Spoon the lemon herb crunch over the hot carrots just before serving.
