Preheat your oven to 425 degrees Fahrenheit and prepare a baking sheet by greasing it with a little bit of oil.
In a large bowl, add the potato wedges after you've washed and dried the potatoes, and cut them into wedges. To cut them into wedges, simply cut them in half lengthwise, in half again lengthwise, and then in half again lengthwise. This will yield about 8 wedges per potato.
Add the potato wedges to a large bowl and add the salt, paprika, garlic powder, pepper, oil and vinegar. Toss very well to combine.
Pour the wedges out onto the prepared baking sheet and arrange them in one layer.
Roast for about 22-25 minutes at 425 degrees Fahrenheit, or until the wedges are very crispy and brown.
Remove them from the oven, toss with some flaky sea salt and a drizzle of vinegar, and serve immediately.
