This creamy scalloped potato dish is a timeless classic that turns simple ingredients into a rich, comforting side perfect for family dinners or holiday feasts. The tender slices of Yukon gold potatoes baked in a velvety sauce with a golden Parmesan crust always bring warmth and satisfaction to the table.
I first made this recipe for a family gathering and it quickly became a requested staple because of its creamy texture and crisp topping that everyone loves.
Ingredients
- Yukon gold potatoes: their creamy texture holds up well in baking and delivers buttery flavor
- Unsalted butter: for a clean, rich base to build the sauce
- Garlic: adds a fragrant depth that complements the creaminess
- All-purpose flour: creates a roux to thicken the sauce without lumps
- Heavy cream: provides the luscious, silky consistency that makes the dish indulgent
- Parmesan cheese: sharp and nutty, it melts into the sauce and crisps on top for texture
- Fresh thyme: offers an herbal brightness that cuts through the richness
- Kosher salt and black pepper: essential simple seasoning that brings all flavors together
Step-by-Step Instructions
- Sauté the Garlic:
- Melt the butter over medium heat in a large pot. Add the minced garlic and cook gently for one minute until the aroma fills the kitchen but without browning it, so it stays sweet and mellow.
- Make the Roux and Sauce:
- Sprinkle the flour into the butter and garlic mixture, stirring continuously to form a smooth paste. Cook it for one to two minutes to get rid of the raw flour taste. Slowly whisk in the heavy cream, keeping the mixture moving so it thickens evenly over about five minutes. Once thickened, stir in the Parmesan cheese, fresh thyme, salt, and black pepper until you have a rich, smooth sauce.
- Prepare the Potatoes:
- Peel the Yukon gold potatoes and slice them very thin, ideally using a mandoline for uniform thickness. This ensures they cook evenly and soak up the sauce.
- Combine Potatoes and Sauce:
- Place the potato slices in a large bowl, pour the creamy sauce over them, and toss gently to coat every piece completely, which helps the flavors penetrate during baking.
- Arrange and Bake:
- Grease a ceramic or glass baking dish well. Begin standing the potato slices upright along the sides and bottom of the dish, packing them tightly but carefully. Pour any remaining sauce over the top and sprinkle extra Parmesan cheese for that irresistible golden crust. Cover with foil and bake in a 400-degree oven for 30 minutes. Remove the foil and bake for another 30 minutes or until the top is bubbling and beautifully browned.
- Rest Before Serving:
- Allow the scalloped potatoes to rest for about 10 minutes out of the oven. This helps the creamy sauce settle, making it easier to serve and letting the flavors deepen.

Storage Tips
Store leftovers covered tightly in the refrigerator for up to four days. Reheat gently in the oven at a low temperature to preserve the creamy texture without drying it out. Avoid microwaving which can make the potatoes rubbery.
Ingredient Substitutions
Gruyere cheese works beautifully in place of Parmesan for a nuttier, richer taste. If you want a lighter option, half and half can replace heavy cream but expect a slightly thinner sauce. Fresh rosemary could replace thyme if you prefer a stronger herb flavor.
Serving Suggestions
This dish pairs wonderfully with roast chicken, glazed ham, or a simple green salad for some textural contrast. A squeeze of lemon or a light drizzle of balsamic reduction adds a bright finish if you’re feeling adventurous.
Cultural Context
Scalloped potatoes have roots in European cooking traditions where potatoes were a daily staple. The creamy, cheesy topping evolved over time into the versions we enjoy today in many Western households, especially in holiday meals.
