Rinse your potatoes and slice each of them in half and score the insides in a diamond pattern.
Place a stick of butter in a 9X13 baking dish and place it in the oven. Heat the oven to 400 degrees F and once the butter is melted in the pan, take it out and set the pan aside.
In a medium mixing bowl, add parmesan, garlic salt, onion powder, italian seasonings and seasoning salt and whisk together.
Now pour the parmesan and seasoning mix into the melted butter in the 9X13 pan and stir together to evenly coat the bottom of the pan.
Place your potatoes sliced side down in the parmesan butter mixture until you fill the pan.
Spray the tops with olive oil and sprinkle with salt.
Bake for 45 minutes then remove and allow the potatoes to cool and crust for about 5 minutes then serve warm.
