how long to bake a sweet potato at 425

The baking time for a sweet potato at 425°F (220°C) will depend on its size and your desired level of doneness. Here are some general guidelines:

– Small sweet potatoes (1-1.5 inches in diameter): 45-60 minutes
– Medium sweet potatoes (1.5-2.5 inches in diameter): 60-75 minutes
– Large sweet potatoes (2.5-3.5 inches in diameter): 75-90 minutes
– Extra-large sweet potatoes (3.5 inches or larger in diameter): 90-120 minutes

To check for doneness, you can:

1. Insert a fork or knife into the sweet potato. If it slides in easily, it’s done.
2. Check the internal temperature with a thermometer. A cooked sweet potato should be at least 205°F (96°C).
3. Squeeze the sweet potato gently. A cooked sweet potato will be soft and yield to pressure.

Remember to poke some holes in the sweet potato with a fork before baking to allow steam to escape. You can also wrap it in foil if you prefer a softer, more moist sweet potato.
