For enhanced flavor, consider adding a pinch of red pepper flakes for a touch of heat. Roasting time may vary depending on the thickness of your carrot slices and the accuracy of your oven. Check for tenderness with a fork. If you don't have fresh oregano, you can substitute 1 teaspoon of dried oregano, but fresh is highly recommended for best flavor. Serve immediately as a vibrant side dish or let cool and add to salads for added sweetness and depth of flavor.
