Creating these crispy potato wedges is a breeze. Just follow the steps below for a perfect batch:

1. Preheat Oven: Preheat your oven to 425°F (220°C).
2. Wash and Cut Potatoes: Thoroughly wash the russet potatoes. Cut them into wedge shapes, approximately 8 wedges per potato.
3. Soak in Water: Soak the potato wedges in cold water for 30 minutes. This helps to remove excess starch.
4. Dry the Wedges: After soaking, drain and thoroughly pat dry the wedges with a clean towel. This step is crucial for achieving crispiness.
5. Season the Wedges: In a large bowl, combine the olive oil, garlic powder, onion powder, paprika, salt, black pepper, and rosemary. Toss in the potato wedges and mix until evenly coated.
6. Arrange on Baking Sheet: Place the seasoned potato wedges in a single layer on a baking sheet lined with parchment paper. Ensure they are spaced apart for even cooking.
7. Bake: Place the baking sheet in the preheated oven and bake for 30-40 minutes, flipping halfway through. Bake until they are golden brown and crispy on the outside.
8. Check for Doneness: You can check that the wedges are done by inserting a fork; it should slide easily through the potato.
9. Garnish: Once baked, remove from the oven and let them cool slightly. Sprinkle with fresh parsley for a touch of color and flavor.
10. Serve Hot: Enjoy your crispy potato wedges immediately while they are still warm and crispy.

These steps will guide you perfectly in creating amazing crispy potato wedges every time.
