What oven temperature should you use to bake sweet potatoes for over 4 hours?

You shouldn't bake sweet potatoes for over 4 hours! It's likely they'll become dry and tough.

Here's a better approach:

* Optimal Baking Time: Sweet potatoes typically bake in a 400°F (200°C) oven for 45-60 minutes, depending on their size.

* Low and Slow: If you want to cook them at a lower temperature, you can bake them at 350°F (175°C) for about 1 hour.

Tips for Baking Sweet Potatoes:

* Prick: Use a fork to prick the sweet potatoes all over before baking to allow steam to escape.

* Foil: Wrapping them in foil can help them cook more evenly and prevent them from drying out.

* Check for Doneness: Use a fork or knife to check for tenderness. They should be soft to the touch.

Remember, adjusting the cooking time and temperature is key for achieving the perfect texture and flavor.
