Tips
Cut vegetables into similarly sized pieces so they roast evenly and finish cooking at the same time. Uneven cutting causes some pieces to burn while others remain undercooked.
Don't crowd the baking sheet. If vegetables are packed tightly, they steam rather than roast. Spread them in a single layer for caramelization.
Toss the vegetables halfway through roasting to ensure even browning on all sides and prevent sticking to the pan.
Good to Know
Refrigerate in an airtight container for up to 4 days. Reheat in a 180°C oven for 5-10 minutes or serve cold.
Prepare vegetables and the herb-oil mixture up to 8 hours ahead. Store separately. Assemble and roast just before serving for best texture.
Serve warm or at room temperature as a side dish to grilled proteins, with crusty bread, or as part of a vegetarian spread.
Common Mistakes
Cut vegetables into uneven sizes to avoid some pieces burning while others undercook.
Overcrowd the baking sheet to avoid steaming instead of roasting; spread in a single layer.

FAQ
Can I prepare this dish ahead of time?
Yes, chop vegetables and make the herb-oil mixture up to 8 hours ahead. Store separately in airtight containers. Combine and roast immediately before serving for the best texture and flavor.
Can I freeze roasted vegetables?
Frozen roasted vegetables work best in soups, stews, or grain bowls rather than eaten as-is, as they lose their firm texture when thawed. Freeze in a single layer on a baking sheet before transferring to containers.
What can I serve with roasted vegetables?
Pair with grilled chicken, fish, steak, or lamb. Serve alongside rice, couscous, or pasta. Also works as a topping for hummus bowls, salads, or crusty bread with feta cheese.
