how long to cook a baked potato at 400

The cooking time for a baked potato at 400°F (200°C) depends on the size of the potato and your desired level of doneness. Here are some general guidelines:

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

To check if the potato is cooked, you can:

1. Check for softness: Insert a fork or knife into the potato. If it slides in easily, the potato is cooked.
2. Check the internal temperature: Use a food thermometer to check the internal temperature of the potato. It should be at least 205°F (96°C) for a fully cooked potato.

You can also wrap the potato in foil and bake it at 400°F (200°C) for a more even cooking and to retain moisture.

Keep in mind that these times are approximate, and the actual cooking time may vary depending on your oven and the specific potato you’re using.
