Ingredients You'll Need
Here's what you'll need – nothing too fancy, just good ingredients that work together beautifully.
- 3 lbs Yukon Gold potatoes (peeled and thinly sliced)
- 3 cups Heavy cream
- 4 cloves Garlic (minced)
- 4 Fresh thyme sprigs
- 1/4 teaspoon Nutmeg (freshly grated)
- 1 teaspoon Salt (or to taste)
- 1/2 teaspoon Black pepper (freshly ground)
- 1 1/2 cups Gruyere cheese (shredded)
- 1/2 cup Parmesan cheese (grated)
- 2 tablespoons Butter (unsalted)
Step-by-Step Instructions
- 1
Preheat your oven to 375°F (190°C). Butter a 9x13 inch baking dish generously with 1 tablespoon of butter. This prevents sticking and adds a layer of flavor to the bottom of the potatoes.
~5 min
- 2
In a large saucepan, combine the heavy cream, minced garlic, thyme sprigs, nutmeg, salt, and pepper. Bring the mixture to a simmer over medium heat, stirring occasionally to prevent scorching. Simmering infuses the cream with the garlic and thyme, creating a flavorful base for the dish.
~8 min
Tip: Don't let the cream boil, or it might curdle. - 3
Remove the saucepan from the heat and discard the thyme sprigs. The thyme has already imparted its flavor, so removing the sprigs ensures a smooth, creamy sauce.
~2 min

In a large bowl, toss the sliced potatoes with half of the Gruyere cheese and half of the Parmesan cheese. This ensures each layer of potatoes is coated in cheesy goodness.
~5 min
- 5
Arrange a layer of potato slices in the prepared baking dish, overlapping them slightly. This creates a stable base and allows the cream to penetrate evenly.
~3 min
- 6
Pour about one-third of the cream mixture over the potato layer, ensuring all the potatoes are moistened. The cream adds moisture and flavor to each layer.
~1 min
- 7
Repeat layers of potatoes and cream, ending with a layer of potatoes. Try to arrange the potatoes in a visually appealing manner for a better final presentation.
~5 min
- 8
Pour the remaining cream mixture over the final layer of potatoes. Press down gently on the potatoes to ensure they are submerged in the cream.
~2 min
- 9
Sprinkle the remaining Gruyere and Parmesan cheese evenly over the top. Dot the top with the remaining tablespoon of butter cut into small pieces. This creates a beautiful golden-brown crust.
~3 min
- 10
Cover the baking dish with aluminum foil and bake for 45 minutes. Covering with foil prevents the top from browning too quickly and allows the potatoes to cook through evenly.
~45 min
- 11
Remove the foil and bake for an additional 15-20 minutes, or until the potatoes are tender and the cheese is melted and golden brown. A knife inserted into the potatoes should meet little resistance.
~17 min
- 12
Let the scalloped potatoes rest for 10-15 minutes before serving. This allows the sauce to thicken slightly and the flavors to meld together.
~13 min
Tip: Resting is important for optimal texture and flavor.
How Do I Know It's Ready?
Potatoes should be easily pierced with a fork or knife, and the cheese topping should be bubbly and golden brown.
