Ingredients
-
4 tablespoons unsalted butter, softened and divided
-
3 pounds (about 4–5 medium) russet potatoes, peeled
-
1 cup heavy cream
-
½ cup shredded white cheddar cheese
-
6 tablespoons grated Parmesan cheese, divided
-
3 garlic cloves, minced
-
Salt and freshly ground black pepper, to taste
Instructions
-
Preheat & Prep
Preheat oven to 375°F (190°C).
Grease a baking dish (around 9×13 inches or similar) with 2 tablespoons of the softened butter. -
Slice Potatoes
Thinly slice the peeled potatoes — a mandolin works best for even, paper-thin slices. -
Make the Cream Mixture
In a large mixing bowl, combine:-
1 cup heavy cream
-
½ cup shredded white cheddar
-
4 tablespoons grated Parmesan
-
3 minced garlic cloves
-
Salt and pepper to taste
-
-
Coat the Potatoes
Add the sliced potatoes to the cream mixture and toss gently until all slices are evenly coated. -
Arrange in Dish
Vertically arrange the coated potato slices in the greased dish, keeping them upright like a domino effect. Continue until all slices are used. -
Add Remaining Cream Mixture
Pour any leftover cream mixture evenly over the arranged potatoes. Lightly season the top with a little extra salt and pepper. -
Top with Butter
Dot the top with the remaining 2 tablespoons of butter, distributing it evenly. -
First Bake
Cover the dish tightly with foil and bake for 35 to 40 minutes. -
Uncover & Finish Baking
Remove foil, sprinkle the remaining 2 tablespoons of Parmesan over the top, and bake uncovered for an additional 25 to 30 minutes, or until potatoes are tender and golden. -
Broil for Crispiness (Optional)
If desired, broil on high for 1 minute to brown the top beautifully. Watch closely to avoid burning. -
Cool & Serve
Let the dish rest for 10 minutes before serving. This allows the cream to thicken slightly for easier slicing and serving.
