Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with olive oil.
Wash and peel the potatoes, then slice them into thin, even rounds about 1/8-inch thick using a sharp knife or mandoline slicer.
In a large mixing bowl, toss the potato slices with olive oil, salt, black pepper, garlic powder, and Italian seasoning until evenly coated.
Layer one-third of the potato slices into the prepared baking dish, slightly overlapping the edges.
Spread 1/2 cup of marinara sauce evenly over the potatoes, then sprinkle 1/3 cup of Parmesan cheese and 1/2 cup of mozzarella cheese on top.
Repeat the layering process two more times, ending with the cheese layer on top for a total of three layers.
Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes.
Remove the foil and bake for an additional 15 minutes, or until the cheese is golden and bubbly, and the potatoes are fork-tender.
Let the casserole cool for a few minutes, then garnish with fresh basil leaves if desired. Serve warm and enjoy!
