Ingredients
2 lbs potatoes, thinly sliced
1 cup heavy cream
1/2 cup whole milk
1 cup shredded Gruyère cheese
1/2 cup grated Parmesan cheese
2 cloves garlic, minced
2 tbsp butter
1 tsp fresh thyme leaves
1/2 tsp salt
1/2 tsp black pepper
1 tbsp olive oil
Instructions
Preheat the oven to 375°F (190°C) and lightly grease a baking dish with butter.
In a saucepan, warm the cream, milk, minced garlic, salt, and pepper over medium heat until hot but not boiling.
Arrange half of the thinly sliced potatoes in the baking dish, slightly overlapping them.
Pour half of the cream mixture over the potatoes and sprinkle with half of the Gruyère and Parmesan cheeses.
Add the remaining potatoes in another layer, then pour the rest of the cream mixture on top.
Sprinkle the remaining cheeses evenly over the surface and drizzle lightly with olive oil.
Cover with foil and bake for 35 minutes.
Remove the foil and bake an additional 20–25 minutes until the top is golden and bubbling.
Garnish with fresh thyme before serving
