1. Cut potatoes into 1- to 1 1/2-inch-thick pieces. Stir together mayonnaise and seasoning in a large bowl; add potatoes, tossing to coat. Place potatoes in a single layer in a lightly greased broiler pan or 15- x 10-inch jelly-roll pan.
2. Bake at 450° for 40 to 45 minutes or until potatoes are tender and browned, stirring once after 20 minutes. Transfer to a serving dish, and sprinkle with parsley.
