How long do you cook more than 1 potato in the oven?

The cooking time for multiple potatoes in the oven depends on several factors:

* Size of the potatoes: Larger potatoes will take longer to cook than smaller ones.

* Type of potato: Some varieties, like russets, are denser and require longer cooking times than others, like red potatoes.

* Oven temperature: A higher temperature will shorten the cooking time.

* Method of cooking: If you're roasting, the potatoes may take longer than if you're baking them.

Here's a general guideline:

* Small potatoes (1-2 inches in diameter): 20-30 minutes at 400°F (200°C)

* Medium potatoes (2-3 inches in diameter): 30-45 minutes at 400°F (200°C)

* Large potatoes (over 3 inches in diameter): 45-60 minutes at 400°F (200°C)

To check if your potatoes are done:

* Insert a fork into the center of the potato. If it goes in easily and the potato feels soft, it's done.

* Cut a potato open. If the inside is cooked through and fluffy, it's done.

Tips for cooking multiple potatoes in the oven:

* Space the potatoes out on the baking sheet: This allows for even cooking.

* Toss the potatoes with oil, salt, and pepper: This will give them a crispy exterior.

* Use a baking sheet with sides: This will prevent the potatoes from rolling around in the oven.

Remember that these are just general guidelines, and you may need to adjust the cooking time depending on your specific oven and potatoes.
