Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
Scrub potatoes clean (peel if desired) and cut into wedge-shaped halves or quarters.
In a bowl, toss potato wedges with olive oil, garlic powder, paprika, onion powder, thyme, salt, and pepper until evenly coated.
Spread wedges in a single layer on the baking sheet (avoid overcrowding).
Bake for 30–35 minutes, flipping halfway, until crispy and golden.
Sprinkle with Parmesan cheese and fresh parsley. Serve with ketchup, aioli, or your favorite dip!
