Preparation
- Preheat your oven to 375°F (190°C) and butter a 9x13 inch baking dish.
- Slice the potatoes about 1/8 inch thick; a mandoline can help achieve consistent thickness.
Cooking
- In a saucepan, combine heavy cream, minced garlic, salt, and pepper, then heat until simmering.
- Arrange one-third of the sliced potatoes in the baking dish, overlapping slightly, and sprinkle with one-third of the Gruyere cheese.
- Pour one-third of the hot cream mixture over the potatoes and cheese, then repeat these layers two more times.
- Cover the baking dish with foil and bake for 25 minutes, then uncover and bake for another 20-25 minutes until golden brown and bubbly.
Serving
- Let the au gratin potatoes rest for 10 minutes before serving, and garnish with fresh parsley if desired.
Tip 1: For extra flavor
- Add a pinch of nutmeg to the cream mixture for a subtle, warm spice that complements the cheese.
Tip 2: For lighter consistency
- Replace half a cup of heavy cream with chicken broth to reduce richness without sacrificing flavor.
Tip 3: For crispy topping
- Sprinkle half a cup of grated Parmesan cheese on top during the last 10 minutes of baking for a crispy, cheesy crust.
Notes
For best results, use firm, starchy potatoes like Russet or Yukon Gold. Ensure potatoes are sliced uniformly for even cooking. Adjust baking time as needed based on your oven and potato thickness.
