In a large bowl, toss the carrots with 4 teaspoons of the oil. Add the za'atar, ½ teaspoon pepper, salt, and cumin. Toss to evenly coat the carrots. Arrange the carrots in a single layer on a baking sheet. Bake for 18 minutes or until tender and lightly browned, stirring every so often.
Return carrots to the bowl and drizzle with the lemon juice.
Serve carrots with labne. Drizzle with the remaining olive oil and a fresh grating of black pepper and sprinkle on the fresh parsley.
Notes
If you're carrots came with bright green tops, save them and make Carrot Top Pesto.
