Cut 1 1/2 pounds of peeled carrots into 3-inch sticks. Place them on a baking sheet and add 2 tablespoons olive oil, 1 teaspoon ground cumin, and 1/2 teaspoon kosher salt. Toss well to coat evenly. Roast in a 400°F oven for 30 minutes, turning after 15 minutes. Reserve about 1 cup of the carrots for another use.
