⏱ 1 hr 20 min · medium · 🍽 serves 4

Ingredients

• 4 lb sweet potatoes, peeled and sliced 1/8 inch thick
• 2 cups heavy cream
• 4 garlic cloves, smashed
• 6 sprigs thyme
• 2 cups grated Gruyere
• Fresh nutmeg
• 2 tsp kosher salt
• Black pepper

Steps

1. Heat the oven to 375F and butter a 9x13 dish.
2. Warm the cream with the garlic and thyme until steaming, then take it off the heat and let it sit 10 minutes. Fish out the garlic and thyme.
3. Layer a third of the sweet potatoes in the dish, season with salt, pepper and a scrape of nutmeg, then a third of the cheese. Repeat twice.
4. Pour the infused cream over the top and press down so the potatoes are submerged.
5. Cover with foil and bake 40 minutes, then uncover and bake 25-30 more until the top is deeply browned and a knife meets no resistance.
6. Rest 15 minutes before serving or it will run.
