how to cook sweet potatoes in oven

To cook sweet potatoes in the oven:

1. Preheat the oven to 400°F (about 200°C).
2. Wash the sweet potatoes thoroughly to remove dirt. Optionally, dry them and brush or spray with olive oil, and sprinkle with salt.
3. Place the sweet potatoes on a parchment-lined baking sheet.
4. Bake for about 40 to 90 minutes depending on their size; smaller ones take about 40-50 minutes, larger ones up to 90 minutes.
5. To check doneness, the flesh should be very soft and the skin should easily pull away or a fork should pierce the potato easily.
6. Optionally, flip the potatoes halfway through baking for more even cooking.
7. Remove from the oven and let cool slightly before serving.

This method results in tender, creamy sweet potatoes with crispy skin if oiled, which can be served plain or with toppings such as butter, cinnamon, or savory options.
