Place the potatoes in a pot, cover with water, and add a pinch of salt. Bring to a boil and cook until the potatoes are fork-tender. (About 10-15 minutes.) Drain and let cool for a few minutes.
Preheat your waffle maker and oil it (important, to prevent sticking).
Place a potato on your waffle maker and smash it.
Then raise the lid and sprinkle on the cheese and spices.
Close the waffle iron and cook for about 5-7 minutes or until the potatoes are crispy and golden brown, and the cheese is melted. Cooking times may vary, depending on your waffle iron.
Carefully remove the cheesy waffle iron potatoes and let them cool for a minute. Serve with your favorite baked potato toppings.
