1. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. In a large mixing bowl, combine the cubed potatoes, Lipton Onion Soup mix, olive oil, and garlic powder. Toss until the potatoes are well coated.
3. Spread the potatoes in a single layer on the prepared baking sheet. This ensures even cooking and a nice, crispy exterior.
4. Roast in the preheated oven for about 25-30 minutes, or until the potatoes are golden brown and tender when pierced with a fork. Halfway through, give them a little toss for even crisping.
5. Once done, remove from the oven and let them cool slightly before sprinkling with fresh parsley and black pepper.

From my experience, the best way to gauge doneness is the aroma—when your kitchen smells like a cozy family gathering, you know these potatoes are ready to be devoured!
