Preheat oven to 400˚F.
Line a large baking sheet with parchment paper and set aside.
Cut each potato in half, then continue to cut each half into four wedges, so you have 8 wedges total from each potato.
Transfer potatoes to prepared baking sheet.
Melt butter in a medium bowl or glass measuring cup; add olive oil to melted butter and whisk in salt, Italian Seasoning, garlic powder, paprika, onion powder, and black pepper.
Pour oil mixture over the potatoes and toss to coat.
Arrange potato wedges in one layer on the baking sheet.
Sprinkle with Parmesan cheese.
Bake for 35 minutes, turning potatoes to opposite cut side halfway through cooking.
If you want to crisp up the wedges, broil during the last 2 minutes.
Remove from oven.
Sprinkle with more Parmesan cheese.
Garnish with parsley and serve warm.
