Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish with a small amount of olive oil or butter.
Peel the potatoes and slice them into thin, uniform rounds about 1/8-inch thick. Use a mandoline slicer if available for even cuts.
Peel the onion, slice it in half, and then thinly slice into half-moons.
In a large skillet, heat the butter and olive oil over medium heat until melted and bubbling. Add the sliced onions and sauté for 5-7 minutes, stirring occasionally, until they soften and become slightly caramelized.
In a large mixing bowl, combine the sliced potatoes, sautéed onions, garlic powder, salt, and black pepper, mixing well to evenly coat the ingredients.
Layer half of the potato-onion mixture in the prepared baking dish, spreading it out evenly.
Sprinkle 1 cup of the shredded cheddar cheese over the first layer of potatoes and onions.
Add the remaining potato-onion mixture on top, spreading it evenly over the first layer.
Cover the dish tightly with aluminum foil and bake in the preheated oven for 35 minutes.
Remove the foil, sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top, and return the dish to the oven. Bake uncovered for another 15 minutes, or until the cheese is melted, bubbly, and golden brown.
Remove the dish from the oven and let it rest for 5 minutes before serving. Garnish with freshly chopped parsley if desired.
