Ingredients
- 2 pounds russet potatoes, peeled and thinly sliced
- 1 cup heavy cream
- 1 cup whole milk
- 2 cups shredded sharp cheddar cheese
- 1 cup shredded Gruyère cheese (or more cheddar if preferred)
- 3 cloves garlic, minced
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon cayenne pepper (optional, for heat)
- 1/4 cup unsalted butter, melted
- Fresh chives or parsley, chopped (for garnish)
Instructions
- Step 1: Preheat your oven to 375°F (190°C). Peel and thinly slice the russet potatoes to about 1/8 inch thickness, using a mandoline if available for even slices.
- Step 2: In a medium saucepan over medium heat, combine heavy cream, whole milk, minced garlic, salt, black pepper, and cayenne pepper if using. Heat until just simmering, then remove from heat.
- Step 3: Stir in the shredded cheddar and Gruyère cheese until fully melted and the sauce is smooth.
- Step 4: Grease a 9×13 inch baking dish. Layer half of the sliced potatoes in the dish, then pour half of the cheese sauce over them.
- Step 5: Add the remaining potatoes and top with the remaining cheese sauce. Drizzle the melted butter evenly over the top.
- Step 6: Cover the dish with aluminum foil and bake for 30 minutes. Then remove the foil and bake for another 20 to 30 minutes, until the potatoes are tender and the top is golden brown and bubbly.
- Step 7: Remove from the oven and let cool for a few minutes. Garnish with chopped chives or parsley. Serve warm as a comforting side dish.

Cheese Sauce
- 1 cup heavy cream
- 1 cup whole milk

- 1 cup shredded Gruyère cheese (or more cheddar if preferred)

- 1/2 teaspoon salt
- 1/2 teaspoon black pepper

Finishing
- 1/4 cup unsalted butter, melted
- Fresh chives or parsley, chopped (for garnish)
Instructions
- Prepare the Potatoes: Preheat your oven to 375°F (190°C). Peel and thinly slice the russet potatoes to about 1/8 inch thickness, preferably using a mandoline slicer for uniform slices.
- Make the Cheese Sauce: In a medium saucepan over medium heat, combine the heavy cream, whole milk, minced garlic, salt, black pepper, and cayenne pepper if using. Heat the mixture just until it begins to simmer, then remove from heat. Stir in the shredded sharp cheddar and Gruyère cheeses until fully melted and the sauce is smooth.

Repeat by layering the remaining potatoes and topping with the remaining cheese sauce. Drizzle the melted unsalted butter evenly over the top.
- Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes. After 30 minutes, remove the foil and continue baking for an additional 20 to 30 minutes, or until the potatoes are tender and the top is golden brown and bubbly.
- Serve: Remove the potatoes from the oven and let them cool for a few minutes. Garnish with freshly chopped chives or parsley and serve warm as a delicious side dish.
