Creating Crispy Roasted Potatoes is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 425°F (220°C).
2. Prepare Potatoes: Wash and dry the potatoes thoroughly. If using larger potatoes, cut them into equal-sized chunks or wedges for even cooking.
3. Seasoning Mix: In a large bowl, combine olive oil, garlic powder, onion powder, rosemary, salt, and pepper.
4. Toss Potatoes: Add the potatoes to the bowl and toss them until well coated in the seasoning mix.
5. Spread on Baking Sheet: Arrange the seasoned potatoes in a single layer on a baking sheet. Ensure they have enough space to roast evenly.
6. Roast: Place the baking sheet in the preheated oven and roast for 30-40 minutes, flipping the potatoes halfway through for even browning.
7. Check for Doneness: The potatoes are done when they are golden brown and crispy on the outside and tender inside. You can test this by piercing them with a fork.
8. Garnish: Remove from the oven and garnish with fresh parsley if desired.
9. Serve Warm: Transfer the potatoes to a serving dish and serve immediately while hot and crispy.

These steps will guide you in creating these incredible roasted potatoes effortlessly.
