Toasting the cumin seeds before adding them to the carrots enhances their aroma and flavor. For extra sweetness, add a drizzle of maple syrup or agave nectar during the last 10 minutes of baking. If you don't have parchment paper, you can roast the carrots directly on the baking sheet. Just be sure to toss them halfway through to prevent sticking. Feel free to experiment with other spices, such as coriander, smoked paprika, or chili powder, to customize the flavor profile.
