Detailed Directions and Instructions
Step 1: Preheat the Oven
Preheat the oven to 180°C (350°F).
Step 2: Prepare the Cream Mixture
In a jug, combine the melted butter, cream, and minced garlic. Stir well to ensure the ingredients are fully combined.
Step 3: Slice the Potatoes
Peel the potatoes and slice them into 3 mm (1/8 inch) thick rounds. Ensure that the slices are uniform for even cooking.
Step 4: Layer the Potatoes
In a baking dish, layer one-third of the potato slices. Evenly pour one-third of the cream mixture over the potatoes, and then sprinkle with one-third each of the salt, pepper, thyme, and grated cheese.
Step 5: Repeat the Layering Process
Repeat the layering process twice more until all ingredients are used, finishing with the remaining cheese on top.
Step 6: Cover and Bake
Cover the dish with foil and bake for 1 hour. This helps the potatoes to cook through and absorb the flavors.
Step 7: Uncover and Brown the Top
Remove the foil and bake for an additional 25-30 minutes, or until the top is golden and bubbly. Keep an eye on it to prevent burning.
Step 8: Let it Rest
Allow the dish to rest for 5 minutes before serving. This will help the layers settle and make it easier to serve.
Notes
Potato Selection
Choose starchy potatoes such as Russet, Sebago, or Maris Piper for the best texture and flavor in the dish.
Thyme Usage
Fresh thyme leaves are optional but recommended for added flavor. If unavailable, dried thyme can be used in a pinch, but reduce the quantity.
Grating Cheese
For optimal melting and flavor, use freshly grated Gruyère cheese. Pre-packaged cheese often contains anti-caking agents which can affect melting.
Resting Time
Do not skip the resting time; it allows the layers to firm up slightly, making serving easier and helping the flavors meld.

Cook techniques
Layering
Layering involves stacking ingredients in a dish to create depth and flavor. In this recipe, potatoes, cheese, and cream are alternately layered to ensure even cooking and distribution of flavors.
Peeling and Slicing Potatoes
Peeling removes the skin to achieve a smooth texture. Slicing the potatoes into uniform 3 mm (1/8 inch) rounds ensures even cooking and prevents some slices from becoming mushy while others remain hard.
Combining Ingredients
Mixing the melted butter, cream, and minced garlic creates a rich sauce that will infuse the potato layers with flavor. This step is crucial for achieving a creamy texture.
Baking
Baking solidifies the dish, allowing the flavors to meld and the top to become golden and bubbly. Initially covering it with foil traps steam, promoting cooking, while removing it later aids in browning.
Resting
Allowing the dish to rest for 5 minutes before serving lets the layers set, making it easier to serve while enhancing the flavors.
