In a small bowl, combine the spices for the Big Daddy seasoning.
In a large bowl, combine cut potatoes and olive oil. Add rosemary, thyme, garlic and Big Daddy Seasoning. Toss to coat.
Place in a single layer on a greased baking sheet. Bake uncovered for 20 to 25 minutes or until tender, turning once. Remove from oven and toss with chopped parsley.
