Follow these simple steps to create roasted red potatoes that are crispy, flavorful, and utterly irresistible:

1. Preheat the Oven: Start by preheating your oven to 425°F (220°C).
2. Wash the Potatoes: Rinse the red potatoes thoroughly under cold water to remove any dirt. Pat them dry with a towel.
3. Cut the Potatoes: Chop the potatoes into bite-sized pieces, aiming for uniform sizes to ensure even cooking.
4. Season the Potatoes: In a large bowl, combine the olive oil, garlic powder, onion powder, paprika, rosemary, salt, and pepper. Mix well.
5. Toss the Potatoes: Add the chopped potatoes to the bowl and toss until they are evenly coated with the seasoning mixture.
6. Spread on a Baking Sheet: Arrange the seasoned potatoes in a single layer on a baking sheet lined with parchment paper or aluminum foil for easy cleanup.
7. Roast in the Oven: Place the baking sheet in the preheated oven and roast for 30-35 minutes, or until the potatoes are golden brown and crispy.
8. Stir Occasionally: Halfway through the cooking time, give the potatoes a good stir to ensure even browning.
9. Check for Doneness: The potatoes should be tender when pierced with a fork and have a crispy exterior.
10. Garnish and Serve: Remove from the oven, sprinkle with chopped fresh parsley, and serve immediately.

These steps will guide you in creating roasted red potatoes that are not only delicious but also visually appealing.
