What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Cut vegetables into uniform 1-inch pieces to ensure even roasting.
- 2Spread vegetables in a single layer; overcrowding traps steam and prevents browning.
- 3Toss garlic cloves with the vegetables whole or roughly chopped to prevent burning.
- 4Use a heavy-duty rimmed baking sheet for better heat conduction and caramelization.
- 5Add balsamic vinegar immediately after roasting while vegetables are still hot for best absorption.
- 6Leftovers keep well in the fridge for up to 3 days; reheat in a skillet to restore crispness.
