Hot Skillet: Heat a large cast-iron skillet in a 450°F (232°C) oven, then place the baked potatoes in it to keep warm. The skillet will retain heat and keep the potatoes crispy. Warming Drawer: Set your warming drawer to 200°F (93°C) to keep baked potatoes hot and delightful. Sheet Pan on Warming Tray: Keep the baked potatoes on the original sheet pan and set it over a warming tray to maintain their warmth. Caution with Foil, Slow Cookers, and Coolers: While wrapping in aluminum foil, using a slow cooker, or placing in a sealed cooler can keep potatoes warm, these methods may trap steam, potentially making them soggy. Use with care.
