1. Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup.
2. Wash and cut the potatoes into halves or quarters, depending on their size, to ensure even cooking.
3. In a large bowl, combine the olive oil, minced garlic, salt, black pepper, and Italian seasoning if using. Add the potatoes and toss until they are well coated with the mixture.
4. Spread the potatoes in an even layer on the prepared baking sheet, ensuring they have enough space to roast and not steam.
5. Roast in the preheated oven for 35-40 minutes, turning them halfway through, until the potatoes are golden brown and tender when pierced with a fork.
6. Remove the baking sheet from the oven and immediately sprinkle the hot potatoes with the grated parmesan. Toss gently to coat them evenly.
7. Transfer to a serving dish and garnish with fresh parsley for a pop of color and freshness.

As you make these potatoes, remember to let your senses guide you. The sizzle of the oil, the aroma of the roasting garlic – these are your cues that something delicious is happening.
