Preheat oven to 400F, with rack on middle position.
In a large bowl, combine potatoes with 2 TB parmesan, dried onion, garlic powder, salt, pepper, and olive oil. Toss until potatoes are completely coated.
Arrange potatoes into a single layer on large baking sheet. Sprinkle tops of potatoes evenly with remaining 2 TB parmesan.
Cover with foil and bake for 20 minutes. Uncover and bake 20-25 min more, or until potatoes are to desired tenderness and golden brown on top.
Notes
For the best results, make sure to slice your red potatoes to a 1/2 inch thickness. This will allow them to cook evenly and soak up all the delicious flavors.
If you'd like your Parmesan Roasted Potatoes to have crispier edges and more browning, bake them a bit longer. Just keep an eye on them to make sure they don't burn.
These potatoes are the perfect side for a gazillion meals. We love serving ours with some Juicy, Tender Meatloaf for a match made in heaven.
