Preheat your oven to 375°F (190°C).
Spray a 9x13-inch baking dish with non-stick cooking spray to prevent sticking.
Wash, peel, and thinly slice the potatoes into 1/8-inch-thick rounds. Use a mandoline slicer if available for even slices.
In a medium saucepan over medium heat, melt the butter. Once melted, whisk in the flour to create a roux and cook for 1-2 minutes until golden and bubbly.
Slowly pour the milk into the roux while whisking constantly to avoid lumps. Cook the mixture for 3-4 minutes, stirring frequently, until it thickens.
Reduce the heat to low and stir in the cheddar cheese, Parmesan cheese, garlic powder, onion powder, salt, and black pepper. Mix until the cheese is fully melted and the sauce is smooth.
In the prepared baking dish, arrange half of the sliced potatoes in an even layer. Pour half of the cheese sauce over the potatoes, spreading it evenly.
Repeat with the remaining potatoes and cheese sauce, ensuring all the potatoes are evenly coated.
Cover the baking dish tightly with aluminum foil and bake for 40 minutes in the preheated oven.
After 40 minutes, remove the foil and bake uncovered for an additional 20 minutes, or until the potatoes are fork-tender and the top is golden and bubbly.
Remove the dish from the oven and let it rest for 5-10 minutes before serving.
Garnish with chopped fresh parsley, if desired, and serve warm as a flavorful side dish.
