To cook the farro: In a medium saucepan, combine the rinsed farro with at least three cups water. Bring the water to a boil, then reduce heat to a gentle simmer. Cook, stirring occasionally, until the farro is tender to the bite but still pleasantly chewy. Drain off the excess water and return the farro to the pot. Add 1 teaspoon olive oil, the lemon juice, garlic and ½ teaspoon salt. Mix well, then add the chickpeas and stir to combine. Set aside, covered, until you’re ready to assemble.
To roast the carrots: Preheat the oven to 425 degrees Fahrenheit. Line a large, rimmed baking sheet with parchment paper and add the carrots. Drizzle them with 1 tablespoon olive oil and sprinkle with cumin, salt and pepper. Roast for 20 to 35 minutes, until the carrots are easily pierced by a fork near the top of their stems.
To toast the pepitas: In a small skillet over medium heat, warm ½ teaspoon olive oil until shimmering. Add the pepitas and generous pinches of cumin, chili powder and salt. Cook, stirring frequently, until the pepitas are turning golden on the edges. Remove from heat to cool.
To make the herbed crème fraîche, combine the crème fraîche, 1 tablespoon chopped parsley, water, and a few dashes of salt and pepper in a small bowl. Stir to combine and set aside.
To assemble the dish, pour the farro and chickpea mixture onto a large serving platter. Arrange the carrots in a single layer over the mixture. Drizzle herbed crème fraîche generously over the carrots, then sprinkle them with pepitas and one tablespoon chopped fresh parsley. Serve immediately or let the dish cool to room temperature.
