Ingredients

• 800 grams Yukon Gold potatoes
• 200 grams Roasted red peppers (jarred or homemade)
• 250 ml Heavy cream
• 150 ml Whole milk
• 2 pieces Garlic cloves, minced
• 100 grams Gruyère cheese, grated
• 1 tablespoon Unsalted butter (for greasing)
• 1 teaspoon Fresh thyme leaves
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.25 teaspoon Nutmeg, freshly grated

Directions

Step 1

Preheat your oven to 180°C (350°F).

Step 2

Peel the Yukon Gold potatoes and thinly slice them into 2-3mm rounds using a sharp knife or mandoline slicer. Rinse the slices under cold water to remove excess starch, then pat dry with paper towels.

Step 3

Grease a baking dish (approximately 9x13 inches) with the unsalted butter, ensuring all corners are coated.

Step 4

Drain the roasted red peppers if using jarred ones, and slice them into thin strips.

Step 5

In a small saucepan, combine the heavy cream, whole milk, minced garlic, salt, black pepper, nutmeg, and thyme leaves. Heat over medium-low heat until warm but not boiling, stirring occasionally. Remove from heat and set aside.

Step 6

Arrange one-third of the potato slices in an even layer in the prepared baking dish. Top with half of the roasted red pepper strips. Sprinkle one-third of the Gruyère cheese over the layer.

Step 7

Repeat the layering process: Add another third of the potatoes, the remaining roasted red peppers, and another third of the cheese.

Step 8

Finish with the final layer of potatoes and pour the warm cream mixture evenly over the dish, ensuring it seeps through all the layers. Press gently to compact the layers.

Step 9

Sprinkle the remaining Gruyère cheese evenly across the top.

Step 10

Cover the baking dish with aluminum foil and bake in the preheated oven for 40 minutes.

Step 11

Remove the aluminum foil and bake for an additional 30 minutes, or until the top is golden brown and bubbling, and the potatoes are tender when pierced with a knife.

Step 12

Allow the dish to rest for 10 minutes before serving. Garnish with additional thyme leaves if desired.
