Description
This casserole features tender slices of Yukon Gold potatoes enveloped in a silky blend of heavy cream, whole milk, garlic, Parmesan, and melted mozzarella.

Ingredients Quantity
2½ lbs Yukon Gold potatoes, thinly sliced
2 cups heavy cream
1 cup whole milk
3 cloves garlic, minced
1½ cups grated Parmesan cheese
1 cup shredded mozzarella cheese
Salt & pepper to taste
2 tbsp butter (for greasing)
Fresh parsley (for garnish)
Instructions
Preheat Oven:
Preheat your oven to 375°F (190°C).
Prepare the Baking Dish:
Generously grease a 9×13-inch baking dish with butter.
Prepare the Potatoes:
Wash and thinly slice Yukon Gold potatoes evenly (about ⅛-inch thick). A mandoline slicer works best for uniform slices.
Make the Cream Mixture:
In a saucepan over medium heat, combine heavy cream, whole milk, and minced garlic. Heat gently (do not boil). Season with salt and pepper.
Layer the Casserole:
Arrange a layer of sliced potatoes in the dish. Pour some cream mixture over them. Sprinkle Parmesan and mozzarella. Repeat layers until all ingredients are used, finishing with cheese on top.
Bake:
Cover with foil and bake for 40 minutes. Remove foil and bake an additional 20–25 minutes, or until the top is golden brown and the potatoes are fork-tender.
Rest & Garnish:
Let rest for 10–15 minutes before serving. Garnish with fresh parsley.
Origin and Cultural Significance
Cream-based potato gratins trace back to French culinary tradition, particularly dishes like Gratin Dauphinois. American steakhouses later adopted and enriched the concept, adding generous cheese and cream to create heartier versions. Restaurants such as Ruth’s Chris Steak House helped popularize indulgent steakhouse sides that complement premium cuts of beef. Today, creamy potato casseroles symbolize celebration, hospitality, and upscale comfort dining in American cuisine.
Optional Additions
Add crispy bacon bits between layers
Mix in caramelized onions for sweetness
Sprinkle Gruyère cheese for deeper flavor
Add a pinch of nutmeg to the cream sauce
Top with buttery breadcrumbs for extra crunch
Tips for Success
Slice potatoes evenly to ensure uniform cooking.
Do not skip resting time—it allows the sauce to thicken.
Warm the cream mixture before layering to promote even baking.
If browning too quickly, loosely tent with foil.
For extra richness, add a tablespoon of cream cheese to the sauce.

Embracing Healthful Indulgence
This dish is undeniably rich, but balance makes indulgence enjoyable. Serve alongside roasted vegetables or a fresh green salad to lighten the meal. For a slightly lighter version, substitute half-and-half for part of the heavy cream or reduce the cheese slightly while maintaining flavor.
