Step 1
Preheat oven to 375°F. Grease a 9x13-inch baking dish with butter or oil.
Step 2
Peel and thinly slice the 2 lb potatoes (about 1/8-inch thick). Mince the 2 garlic cloves and chop the 1 tbsp rosemary.
Step 3
In a bowl, whisk together the 1.5 cups heavy cream, 1 egg yolk, minced garlic, chopped rosemary, 1 tsp salt, and 0.5 tsp pepper.
Step 4
Layer half the potato slices in the dish, pour over half the cream mixture, and sprinkle with 1 cup of the Swiss cheese. Repeat with remaining potatoes, cream, and cheese.
Step 5
Cover with foil and bake for 30 minutes. Remove foil and bake until potatoes are tender and top is golden and bubbly, about 15-20 more minutes.
Step 6
Let rest for 5 minutes before serving. Garnish with extra rosemary if desired.
