Preheat the oven to 425° F.
Cut the potatoes in half. If they are large, score each potato in a cross-hatch pattern.
Add the potatoes to a bowl. Add ¼ cup buffalo sauce, olive oil, thyme, parsley, garlic powder, and pepper. Toss to coat.
On the baking sheet mix the parmesan, cheddar, butter, and 2 tablespoons buffalo sauce and season with pepper. Mix to form a paste, then spread in an even layer.
Place the potatoes, cut side down over the cheese. Bake until crispy, 30 minutes.
Use a spatula to release the potatoes. Season with sea salt if desired. Serve with green onions and extra sauce.
