Tender sliced potatoes baked in a garlic cream sauce and topped with golden Parmesan cheese — the perfect side dish for holidays, gatherings, or comfort food dinners.
2½ lbs Yukon Gold or Russet potatoes, peeled and sliced ⅛-inch thick
1½ cups heavy cream
1½ cups whole milk
2 tbsp butter
2 garlic cloves, minced
1½ cups freshly grated Parmesan cheese
1 tsp salt
½ tsp black pepper
Optional: pinch of nutmeg, 1 tsp chopped fresh thyme
Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter.
In a saucepan, melt butter and sauté garlic until fragrant. Add cream, milk, salt, pepper, and optional nutmeg. Simmer for 2–3 minutes. Remove from heat.
Layer one-third of the potatoes in the dish. Pour over one-third of the cream mixture and sprinkle with Parmesan. Repeat two more times, finishing with a cheese layer.
Cover with foil and bake for 45 minutes. Uncover and bake another 25–30 minutes until golden and tender.
Rest 10–15 minutes before serving.
Make ahead up to 1 day. Try Gruyère or cheddar with the Parmesan. Slice potatoes evenly for best results.
