How Long Does It Take to Roast Carrots and Potatoes in the Oven?

In an oven set to 375 F, cubed potatoes and cut carrots can roast to completion in one hour. However, at a higher temperature, such as 450 F, they are done within 40 to 45 minutes.

Almost all vegetables can be roasted to create a caramelized exterior and intensified flavor. According to Better Homes & Gardens, a particular advantage to roasting is the freedom it gives the cook to prepare a combination of vegetables that may not all yield good results with other techniques, such as boiling or steaming. However, it should be noted that green and non-root vegetables, such as broccoli and green beans, may discolor or dry out at such high temperatures.
