Let the potatoes cool enough to cut into wedges. Place potatoes in large bowl.
Drizzle a bit of the oil into two 15 x 10 x 1 inch baking pans and brush the oil to coat bottoms; place remaining oil on the potatoes and toss to coat. Combine the Parmesan cheese and seasonings in the small bowl and add to the potatoes. Toss to coat. Lay potatoes skin-side down onto pans. Bake, uncovered, at 375° for 20 to 35 minutes or until crispy brown.
