Whether you need to peel hot or baked potatoes before adding toppings and baking again depends on personal preference and the specific recipe you are following. Here are a few considerations:
Texture: Leaving the potato skins on can add texture and flavor to your dish. The skins can become crispy when baked and provide a contrasting texture to the soft interior.
Nutritional value: Potato skins contain additional nutrients such as fiber, vitamins, and minerals. By keeping the skins on, you retain these beneficial elements.
Recipe requirements: Some recipes may call for peeled potatoes to achieve a certain texture or appearance. For example, if you're making mashed potatoes or a dish that requires a smooth consistency, peeling the potatoes would be necessary.
Ultimately, it's up to you whether you prefer to peel the potatoes or leave the skins on. If you enjoy the flavor and texture of potato skins, you can certainly leave them intact when adding toppings and baking again.
