Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Potatoes are the foundation of this casserole. Russet or Yukon Gold potatoes work best, as they become tender while maintaining structure.

Heavy cream creates the rich, silky base of the sauce. It coats the potatoes evenly and delivers a luxurious mouthfeel.

Unsalted butter adds richness and enhances the overall flavor of the dish.

Cream cheese contributes tanginess and helps create a thick, cohesive sauce.

Parmesan cheese provides sharp, savory depth and defines the character of the casserole.

Garlic adds aroma and savory balance, preventing the dish from tasting flat.

Salt seasons the potatoes and enhances the dairy flavors.

Black pepper adds subtle warmth and contrast to the richness.

Fresh parsley is optional but adds color and freshness when used as a garnish.

Directions

Preheat the oven to 190°C (375°F) and lightly grease a baking dish. Peel and dice the potatoes into evenly sized pieces, then place them in a large pot of salted water. Bring to a boil and cook until the potatoes are fork-tender, then drain well.

In a saucepan over low heat, combine the butter, heavy cream, and cream cheese. Stir gently until melted and smooth. Add the garlic, salt, and black pepper, mixing until well incorporated. Remove from heat and stir in the Parmesan cheese until fully melted.

Add the cooked potatoes to the sauce and gently fold until evenly coated. Transfer the mixture to the prepared baking dish and spread evenly. Bake uncovered for 25 to 30 minutes, until heated through and lightly golden on top. Allow the casserole to rest for a few minutes before serving. Garnish with parsley if desired.

For added texture, a breadcrumb topping mixed with melted butter can be sprinkled on top before baking. Bacon crumbles or sautéed onions can also be folded into the potatoes for additional depth.

If you want a lighter version, substitute part of the heavy cream with whole milk, though the texture will be slightly less rich. Fresh herbs such as thyme or chives can be added for a subtle aromatic note. This dish pairs beautifully with beef, chicken, or roasted vegetables, making it versatile for many menus.
