Take potatoes, peel, and cut into 2"x2" cubes. Mush butter around potatoes until they are totally covered. Be careful not to put too much butter though, because they will remain in liquid instead of getting crispy. After butter is applied add pepper, salt, garlic powder, and McCormicks Montreal Steak Seasoning to taste (pepper, salt, garlic powder, and steak seasoning amounts are all approximate because I just do it to taste likes of my family). If you do not like a garlic taste, just remove the garlic powder. Then bake at 425 to 450 degrees for approximately 45 minutes to an hour (or until desired crispness). Take out of the oven and sprinkle freshly grated parmesan cheese on top. Allow the cheese to just melt or put back into oven for a few minutes to get the cheese more melted.
