Ingredients
4 tablespoons unsalted butter, softened and divided
3 pounds russet potatoes (about 4–5 medium potatoes), peeled
1 cup heavy cream
½ cup shredded white cheddar cheese
6 tablespoons grated Parmesan cheese, divided
3 garlic cloves, minced
Salt, to taste
Freshly ground black pepper, to taste
Instructions
Preheat oven to 375°F (190°C).
Grease a baking dish with 2 tablespoons of the softened butter.
Using a mandoline slicer or sharp knife, slice the potatoes very thinly.
In a large mixing bowl, combine the heavy cream, shredded white cheddar, 4 tablespoons Parmesan cheese, and minced garlic.
Add the sliced potatoes and toss until evenly coated in the cream mixture.
Season generously with salt and black pepper and toss again.
Arrange the potato slices vertically in the prepared baking dish, stacking them closely together until the dish is filled.
Pour any remaining cream mixture evenly over the potatoes.
Lightly season the top with additional salt and pepper.
Dot the surface with the remaining 2 tablespoons butter.
Cover the dish tightly with aluminum foil.
Bake for 35–40 minutes.
Remove the foil and sprinkle the remaining 2 tablespoons Parmesan cheese over the top.
Continue baking uncovered for 25–30 minutes, or until the potatoes are fork-tender.
Transfer the dish to the broiler and broil on high for 1 minute, or until the top is golden brown.
Remove from the oven and allow to cool for 10 minutes before serving.
Notes
Russet potatoes are ideal because of their high starch content, creating a creamy texture.
A mandoline slicer helps achieve uniform slices for even cooking.
White cheddar can be substituted with Gruyère, Fontina, or Swiss cheese for different flavor profiles.
Allow the dish to rest before serving to help the cream sauce set.
For extra richness, add a pinch of nutmeg to the cream mixture.
Store leftovers in an airtight container in the refrigerator for up to 4 days.
