Ingredients

• 800 grams Russet potatoes
• 50 grams Unsalted butter
• 250 milliliters Heavy cream
• 100 milliliters Milk
• 2 Garlic cloves
• 2 Thyme (fresh sprigs)
• 1.5 teaspoons Salt
• 0.5 teaspoons Black pepper
• 100 grams Gruyère cheese, grated
• 1 tablespoon Olive oil

Directions

Step 1

Preheat your oven to 180°C (350°F). Lightly grease a medium-sized ovenproof dish with butter or olive oil.

Step 2

Peel the russet potatoes. Grate them using a coarse box grater or a food processor with a grating attachment. Transfer the grated potatoes into a clean kitchen towel and wring out as much moisture as possible.

Step 3

In a small saucepan, combine the heavy cream, milk, peeled garlic cloves, and fresh thyme sprigs. Heat gently over medium-low heat until it just begins to simmer. Take off the heat and let it steep for 5 minutes to infuse the flavors. Remove the garlic and thyme, then stir in 1 teaspoon of salt and 0.5 teaspoons of black pepper.

Step 4

In a large skillet, heat the olive oil and half of the butter over medium heat. Add the grated potatoes, sprinkle with the remaining 0.5 teaspoon of salt, and stir to evenly coat. Cook for 5-7 minutes, stirring occasionally, until the potatoes just begin to soften but not become fully cooked.

Step 5

Transfer half of the potato mixture into the prepared baking dish. Spread evenly into a thin layer and press down gently. Sprinkle half of the grated Gruyère cheese over the potatoes.

Step 6

Pour half of the infused cream mixture evenly over the potato layer. Repeat with the remaining potatoes, spreading into another even layer, then top with the rest of the Gruyère cheese. Finish by drizzling the remaining cream mixture over the top.

Step 7

Dot the top with the remaining butter, cut into small pieces.

Step 8

Bake in the preheated oven for 45-50 minutes, or until the top is golden brown and the potatoes are tender when pierced with a knife.

Step 9

Remove from the oven and let it cool for 5-10 minutes before serving. Garnish with a few thyme leaves, if desired.
