Ingredients
Main Ingredients:
- 2 pounds (900g) Yukon Gold potatoes, thinly sliced
- 1 ½ cups shredded Gruyère cheese
- ½ cup grated Parmesan cheese
- 2 cups heavy cream (or half-and-half for lighter version)
- 2 tablespoons unsalted butter
- 2 garlic cloves, minced
- 1 teaspoon salt
- ½ teaspoon freshly ground black pepper
- ½ teaspoon dried thyme (or 1 teaspoon fresh)
- ¼ teaspoon nutmeg (optional but recommended)
Cooking Directions (Short Format)
- Preheat oven to 375°F (190°C).
- Layer thin potato slices into a buttered baking dish.
- Heat cream, garlic, spices, and butter until warm, then pour over potatoes.
- Add Gruyère and Parmesan cheese between layers and on top.
- Bake until golden, bubbling, and tender — about 55–70 minutes.
- Rest 10 minutes before serving.
Step-by-Step Preparation Method
Step 1 — Prep the Potatoes
- Peel (optional) and slice potatoes very thinly — ideally ⅛ inch (3 mm) thick.
- A mandoline slicer ensures even slices and perfect cooking texture.
Step 2 — Prepare the Cream Mixture
- In a saucepan, add:
- Heavy cream
- Garlic
- Butter
- Salt, pepper
- Thyme
- Nutmeg
- Warm gently over medium heat until butter melts and mixture steams.
(Do not boil.)
Step 3 — Assemble the Dish
- Grease a baking dish with butter.
- Arrange a single overlapping layer of potatoes.
- Sprinkle Gruyère and Parmesan.
- Pour warmed cream mixture over the layer.
- Repeat layers until ingredients are used.
- Finish with a thick layer of cheese on top.
Step 4 — Bake
- Cover with foil and bake 45 minutes.
- Remove foil and bake an additional 15–25 minutes, or until golden and bubbly.
Step 5 — Rest Before Serving
- Let rest 10–15 minutes to set and slice easily.

How to Serve
Serve warm alongside:
- Roast turkey or chicken
- Beef tenderloin or steak
- Baked salmon
- Holiday ham
- Green vegetables (e.g., asparagus, roasted Brussels sprouts)
Garnish with fresh parsley for color.
Recipe Tips
- Use Yukon Gold or Russet potatoes for best tenderness and creaminess.
- Shred Gruyère fresh — pre-shredded cheese won’t melt as smoothly.
- If potatoes brown too quickly, loosely tent with foil.
- Let it rest before slicing — this prevents runny layers.
