Preheat oven to 425 degrees. Spray a large baking sheet (10x15 or larger) with cooking spray or rub with olive oil.
Mix together olive oil, dry soup mixes, garlic powder and pepper in a large mixing bowl.
Wash potatoes then cut into 1-inch pieces, leaving the skin on. Add potatoes to mixing bowl then toss to coat with your hands or a rubber spatula (just make sure the potatoes are evenly coated with oil and seasoning).
Arrange potatoes in a single layer in prepared pan(s). Top potatoes with any oil/soup mix left in the bowl.
Bake at 425 degrees for 35-45 minutes or until gold brown, flipping with a wide spatula halfway through cooking.
