Method
Preparation
Preheat your oven to 350°F (175°C).
In a greased baking dish, layer half of the sliced potatoes.
In a bowl, mix together the heavy cream, milk, minced garlic, salt, and pepper. Pour half of this mixture over the potatoes.
Sprinkle half of the cheddar cheese over the cream mixture.
Repeat the layering with the remaining potatoes, cream mixture, and top with the remaining cheddar cheese and grated Parmesan.
Dot the top with butter.
Cover with foil and bake for 45 minutes.
Remove the foil and bake for an additional 15 minutes or until the top is golden and bubbly.
Let it cool for a few minutes before serving. Garnish with fresh parsley if desired.
