roasted sweet potatoes oven temperature is about 2-25℃, and the time is about 25-3 minutes. The temperature of roasted sweet potatoes in the oven is not invariable, and it needs to be determined according to the size of the sweet potato. If the selected sweet potato is small, then adjust the oven to 22℃ and bake for 25 minutes. If the selected sweet potato is large, you need to raise the oven temperature to about 24℃ and bake for 3 minutes. In addition, there is another situation that our baked sweet potatoes have been heated to half-cooked. At this time, we only need to adjust the oven to 15℃ and bake for about 15 minutes.
