Vegetable Roasting Times

The times indicated are based on the assumption that you place the vegetables in a conventional oven that has been pre-heated to 450 °F or 230 °C. If you are not using a conventional oven or if you use another roasting temperature, the roasting times may differ significantly. The chart below also show the preparation method/size of the vegetable required to achieve the indicated roasting time.

To roast vegetables in a pre-heated conventional oven, place prepared veggies in a baking pan lined with parchment paper in order to prevent them from sticking. Tossing the vegetables with oil will also reduce sticking.

*Roasting time longer than 10-15 minutes (refer to the other charts on this page for the appropriate roasting time for this vegetable). You can overcome the differences in roasting times by putting the longer roasting vegetables into the oven first or by cutting the slow-roasting vegetables into smaller pieces than recommended on this page.
