Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with a bit of olive oil or cooking spray and set aside.
Peel the russet potatoes and slice them into 1/8-inch-thick rounds. Place the sliced potatoes in a large bowl of cold water to prevent browning.
Heat a skillet over medium heat and melt 2 tablespoons of butter. Add the thinly sliced onion and cook until caramelized, about 10 minutes, stirring occasionally. Transfer the onions to a small bowl and set aside.
In a saucepan, melt the remaining 2 tablespoons of butter over medium heat. Add the flour and whisk continuously for 1-2 minutes to form a roux. Slowly pour in the milk while whisking to avoid lumps.
Cook the sauce over medium heat, stirring constantly, until it thickens, about 5 minutes. Remove from heat and stir in 1 1/2 cups of cheddar cheese, 1/4 cup of Parmesan cheese, salt, pepper, and garlic powder until smooth.
Drain the potatoes and pat them dry with a clean kitchen towel. Layer 1/3 of the potato slices in the prepared baking dish, overlapping them slightly.
Spread 1/3 of the caramelized onions over the potatoes, then pour 1/3 of the cheese sauce on top. Repeat this layering process two more times, finishing with the cheese sauce on top.
In a small bowl, combine the breadcrumbs, olive oil, remaining 1/2 cup of cheddar cheese, remaining 1/4 cup of Parmesan cheese, and chopped parsley. Sprinkle this mixture evenly over the top of the casserole.
Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 20 minutes, or until the top is golden and bubbly and the potatoes are tender when pierced with a fork.
Let the Oakhill Potatoes rest for 10 minutes before serving. Garnish with additional parsley, if desired. Serve warm and enjoy!
