Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with cooking spray.
Peel the potatoes and slice them into thin, even rounds about 1/8-inch thick. Use a mandoline slicer if available.
In a medium saucepan over medium heat, melt the butter. Stir in the flour and cook, stirring constantly, for 1 minute to form a smooth roux.
Gradually add the milk and heavy cream, whisking continuously to prevent lumps. Bring the mixture to a gentle simmer and cook until it begins to thicken, about 3-4 minutes.
Stir in the minced garlic, salt, and black pepper. Remove the saucepan from heat and stir in half of the grated Parmesan cheese and 1 cup of the cheddar cheese until melted and smooth.
Arrange half of the sliced potatoes in an even layer in the prepared baking dish. Pour half of the cheese sauce over the potatoes, spreading it evenly.
Repeat the layering with the remaining potatoes and cheese sauce, ensuring the potatoes are fully coated.
Sprinkle the remaining Parmesan cheese and cheddar cheese evenly over the top.
Cover the dish tightly with aluminum foil and bake in the preheated oven for 45 minutes.
Remove the foil and continue baking for an additional 25-30 minutes, or until the top is golden brown and the potatoes are fork-tender.
Allow the dish to sit for 10 minutes before garnishing with chopped parsley and serving warm.
