Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.

Season potatoes: In a large bowl, toss wedges with olive oil, garlic powder, onion powder, paprika, oregano, salt, and pepper until evenly coated.

Coat with cheese: Add Parmesan cheese and toss again.

Arrange & bake: Spread wedges in a single layer on the baking sheet. Bake for 35–40 minutes, flipping halfway, until golden brown and crispy.

Garnish & serve: Sprinkle with parsley and serve with ranch or marinara sauce for dipping.
