What temperature is best for roasting vegetables?

Different vegetables roast for varying amounts of time. This is why it is important to cut vegetables close to the same same size and to roast them with like vegetables for the most uniform cooking.

Root vegetables- Parsnips, carrots, and potatoes take longer (30 min.) to cook at 400 degrees because of their firmness.

Cruciferous- Broccoli and cauliflower will cook for closer to 20 minutes.

Less firm vegetables– Squash, peppers, green beans, and zucchini may only need 15-20 minutes.

When roasting vegetables, should they be covered?

No, becasue the foil will cause them to steam instead of roast.

Can you roast frozen vegetables?

It is not preferred because the water keeps them from getting as crispy as fresh. However, if you need to roast frozen vegetables, do it at a higher temp of 425 to evaporate some of the water.

Tips and Techniques

Double the recipe- To serve a crowd but you will have to use two sheet pans.

How do you prevent vegetables from sticking to the sheet pan? Line the sheet pan with foil and make sure the vegetables are coated adequately with oil. Flip vegetables half way through baking to further prevent sticking.

Why aren’t the vegetables browning? If the vegetables aren’t browning, increase the cooking temp by 15 degrees or roast longer

Size matters- Cut vegetables to similar sizes in order to help them cook evenly

Do I need to flip the vegetables? Yes, make sure to flip the veggies half-way through roasting so they don’t stick and they brown evenly.

How much oil should I use? Don’t use so much oil that there is oil pooling on the pan. This will make them too greasy. Coat the vegetables completely though to help them roast properly.

Does the temperature matter? Don’t roast at too low of a temp. or the vegetables won’t caramelize. Too high of a temp will burn them while still being raw inside. The best range is 400-425 degrees.

Overcrowding- Try not to overcrowd the vegetables. This will prevent caramelization and will take longer. Use a second sheet pan if needed to avoid this.

How long do these vegetables last? They last 1-2 days in the fridge, but will be soft unless you reheat them in the oven to crisp them up again. They taste best fresh from the oven.
