Preheat the oven to 400 degrees F (200 degrees C). Line a baking sheet with aluminum foil.

Cut potatoes into wedges. Rinse and pat dry. Pour olive oil into a large bowl. Add wedges to the oil; mix until coated.

Mix black pepper, oregano, garlic powder, and seasoned salt together in another bowl or a large zip-top bag. Add potato wedges and mix around until evenly coated. Spread wedges on the prepared baking sheet.

Bake in the preheated oven until golden brown and starting to crisp, 20 to 25 minutes.
