Follow these simple steps to create the most delicious Crispy Roast Potatoes with Rosemary and Garlic:

1. Preheat Oven: Preheat your oven to 425°F (220°C). This high temperature is key for achieving crispiness.
2. Prepare the Potatoes: Wash and peel the potatoes (if desired). Cut them into even chunks, about 1-2 inches in size to ensure even cooking.
3. Parboil the Potatoes: Place the cut potatoes in a large pot of salted water. Bring to a boil over medium-high heat, and let them simmer for about 10 minutes. This step helps create a fluffy interior.
4. Drain and Steam: Once parboiled, drain the potatoes in a colander and let them steam dry for a few minutes. This step helps to enhance the texture.
5. Coat with Oil: In a large mixing bowl, toss the steamed potatoes with the olive oil, minced garlic, chopped rosemary, salt, and black pepper. Ensure every piece is well-coated for the best flavor.
6. Spread on Baking Sheet: Spread the potatoes out in a single layer on a baking sheet. Make sure they are not overcrowded; this allows for maximum crispiness.
7. Roast in the Oven: Roast in the preheated oven for 25-30 minutes, flipping them halfway to ensure even browning. Keep an eye on the potatoes; they should be golden brown and crispy.
8. Check for Doneness: Potatoes are ready when they are crispy on the outside and tender on the inside. You can test by poking a fork through them.
9. Garnish: Once done, remove the potatoes from the oven and sprinkle a little more salt and fresh herbs if desired before serving.
