Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper.
In a large bowl, combine the halved baby potatoes, olive oil, oregano, garlic powder, onion powder, salt, black pepper, and red pepper flakes. Toss until the potatoes are evenly coated.
Arrange the potatoes cut-side down on the prepared baking sheet in a single layer, ensuring they are not overcrowded.
Roast in the preheated oven for 25-30 minutes, or until the potatoes are golden brown and crispy on the outside. Flip them halfway through for even cooking.
Once done, remove from the oven and let them cool for a few minutes. Garnish with fresh parsley before serving.
