Oven Roasting Times for Different Vegetables

Oven roasting times for 60 vegetables

Roasting is a great way to prepare vegetables. To ensure your oven-roasted vegetable dishes tantalize your taste buds, it is important to keep in mind that different vegetables require different roasting times. Softer and moister vegetables such as peppers, leeks, zucchini, asparagus, tomatoes, mushrooms, and green beans take less time than hard root vegetables such as potatoes, parsnips, rutabagas, celery root, beets, and carrots.

Combining vegetables with similar roasting times is an easy way to create a delicious, evenly cooked vegetarian side or main dish (for foods with similar roasting times, see charts below). You can of course also combine foods with varied roasting times – just add the faster-cooking vegetables to the oven later or pre-cook hard root vegetables on the stove top.

The charts below show the approximate oven roasting times in minutes for different vegetables. Each chart lists vegetables with similar roasting times to allow you to easily see which vegetables can be roasted together. 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 (gas mark 8). If you are not using a conventional oven or if you use another roasting temperature, the roasting times may differ significantly. You should also note that the way you prepare your veggies will have an impact on how long the roasting time will be (whole vegetables take longer than finely diced or sliced vegetables). The vegetable roasting charts 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; however, if you like healthier recipes, skip the oil. If you are roasting without oil, moisten the vegetables by adding a small amount of water or vegetable stock to the bottom of the roasting pan. Alternatively, you can use chicken broth, wine, tomato juice, freshly pressed orange juice, lemon juice, vinegar, or soy sauce. After arranging the vegetables on the pan, place the pan on the middle rack in the oven. Stir occasionally and cook until tender and lightly browned.

*Roasting time shorter or longer than 15-20 minutes (refer to the other charts on this page for the roasting time for this vegetable). If you want to combine slower and faster roasting veggies, you can do so by putting the slow cooking vegetables into the oven first and by adding the faster cooking food later. Furthermore, cutting slow-roasting vegetables into smaller pieces will shorten the roasting time.
