Preheat the oven to 400 degrees F.

In a large bowl, add the halved potatoes, then pour over the melted butter, garlic powder, dried oregano, salt, and black pepper. Gently toss until well coated.

In a 9x13 inch glass baking dish, add the melted butter and spread it evenly over the bottom. Sprinkle with grated Parmesan cheese.

Place potatoes cut-side down onto the cheese in a single layer. Roast for 35 to 40 minutes until fork-tender and the cheese is golden brown.

Optional: Spread roasted garlic feta dip on the bottom of a platter, then flip the potatoes onto it. Garnish with lemon zest, fresh herbs, and sprinkle with flaky sea salt.
