Preheat: Set your oven to 400°F (200°C). (Higher heat than the original recipe helps the potato sugars caramelize naturally).
Prep: Cut potatoes into wedges, soak for 30 mins, and pat dry.
Coat: In a large bowl, toss wedges with the oil, salt, garlic powder, and onion powder. Ensure every side is glistening but not dripping.
Roast: Spread them out on the pre-heated baking sheet, skin-side down.
Bake: Roast for 30–40 minutes. You don’t need to flip them if they are skin-side down; the bottoms will get beautifully golden and the tops will stay fluffy.
Finish: Taste one. If it’s still too plain, add a tiny extra pinch of salt while they are hot. Salt is the "volume knob" for potato flavor.
