Remember that cooking times may vary depending on the size and type of potatoes, as well as the specific air fryer or oven you're using. There are a few ways to determine if baked potatoes are cooked and ready to be enjoyed: Fork test: Use a fork and insert it into the center of the potato. If it goes in easily with little resistance and slides out smoothly, the potato is likely cooked through and tender. Squeeze: Gently squeeze the sides of the potato. If it gives slightly under pressure and feels soft, it is likely cooked. Internal temperature: Use a meat thermometer to check the internal temperature of the potato. A fully cooked baked potato should register around 205°F (96°C) to 212°F (100°C). Visual appearance: A well-cooked baked potato will have a uniformly soft interior without any raw or firm sections. The skin will also appear crispy and may have slightly pulled away from the flesh.
