Preheat your oven to 425°F (220°C).
Prepare a baking sheet with parchment paper.
Wash the red potatoes thoroughly and cut them into quarters.
In a large bowl, combine the olive oil, garlic powder, onion powder, rosemary, salt, and pepper.
Add the potatoes to the bowl and toss until evenly coated.
Spread the potatoes in a single layer on the prepared baking sheet.
Roast in the preheated oven for 30-35 minutes, flipping halfway through.
Check for doneness by piercing with a fork; they should be tender and golden.
Remove from the oven and let cool for a few minutes.
Garnish with fresh parsley before serving.
