Creating The Best Crispy Roast Potatoes Ever is straightforward if you follow these detailed steps:

1. Preheat the Oven: Start by preheating your oven to 425°F (220°C).
2. Prepare the Potatoes: Wash and peel the potatoes. Chop them into even-sized chunks, approximately 1.5 inches.
3. Parboil: Place the potato chunks in a large pot of salted water. Bring to a boil and cook for about 10 minutes until just tender.
4. Drain: After parboiling, drain the potatoes in a colander and let them steam dry for a couple of minutes.
5. Rough Up the Surface: Shake the colander gently to fluff up the edges of the potatoes. This will create a crispy texture when roasted.
6. Coat with Oil: In a roasting pan, combine olive oil, salt, black pepper, garlic powder, and rosemary. Add the steamed potatoes and toss until well-coated.
7. Spread Evenly: Arrange the potatoes in a single layer in the roasting pan, ensuring they’re not crowded.
8. Roast: Place the pan in the preheated oven and roast for 40-45 minutes, turning every 15 minutes until golden brown and crispy.
9. Serve Immediately: Once roasted, remove from the oven and, if desired, sprinkle with fresh parsley for garnish.

Following these steps will help you achieve the amazing crispy roast potatoes that will leave everyone wanting more!
