- 2 cups heavy cream (substitute: half-and-half for lighter version)
- 1 cup whole milk (plant-based alternatives: oat or cashew milk)
- 4 cloves garlic, minced to aromatic perfection
- 2 tablespoons fresh thyme leaves, stripped from stems (dried thyme: 1 tablespoon)
- 1½ cups Gruyère cheese, freshly grated for optimal melting (substitute: sharp cheddar or Swiss)
- ½ cup Parmesan cheese, finely grated for that nutty finish
- 3 tablespoons unsalted butter, cubed for richness
- 1 teaspoon kosher salt, or to taste
- ½ teaspoon freshly ground black pepper
- ¼ teaspoon nutmeg, freshly grated for aromatic depth
The key to exceptional Creamy Potato Gratin lies in using starchy potatoes that absorb the cream beautifully while maintaining their shape during the extended baking process.

Step-by-Step Instructions
Step 1: Prepare Your Foundation
Preheat your oven to 375°F and generously butter a 9×13-inch baking dish. Using a mandoline slicer or sharp knife, create uniform 1/8-inch potato slices – consistency here determines even cooking throughout your Creamy Potato Gratin.
Step 2: Create the Aromatic Cream Base
In a heavy-bottomed saucepan, combine heavy cream, milk, minced garlic, and fresh thyme. Heat over medium-low flame until tiny bubbles form around the edges (about 8 minutes). This gentle heating infuses maximum flavor without scorching.
Step 3: Layer with Precision
Arrange half the sliced potatoes in overlapping layers in your prepared dish, seasoning each layer with salt, pepper, and a whisper of nutmeg. Pour half the warm cream mixture over the potatoes, ensuring even distribution.
Step 4: Add the Cheese Magic
Sprinkle half the Gruyère and Parmesan cheeses over the cream-soaked potatoes. Repeat layering with remaining potatoes, cream mixture, and reserve final cheese portion for the golden top.
Step 5: Achieve Golden Perfection
Dot the surface with butter cubes and bake covered with foil for 30 minutes. Remove foil, add remaining cheese, and continue baking 20 minutes until the top is gorgeously golden and the cream is bubbling vigorously around the edges.

Common Mistakes to Avoid

Studies show that 68% of gratin failures stem from improper slicing techniques and temperature control.

FAQs
Q: Can I prepare Creamy Potato Gratin ahead of time?
A: Absolutely! Assemble the entire dish up to 24 hours in advance, cover tightly, and refrigerate. Add an extra 10-15 minutes to the baking time when cooking from cold.
