Ingredients

Scale
  • 2 lbs Yukon Gold potatoes, peeled and sliced into 1/8-inch rounds
  • 3 tbsp unsalted butter, plus extra for greasing the pan
  • 5 large cloves fresh garlic, minced
  • 1 cup heavy cream
  • 1/2 cup chicken broth (or vegetable broth for vegetarian)
  • 3/4 cup freshly grated Parmesan cheese
  • 1/3 cup sour cream (optional)
  • 1 1/4 tsp salt (adjust to taste)
  • 1/2 tsp freshly cracked black pepper
  • 1 tbsp fresh thyme leaves (or 1 tsp dried thyme)
  • 1/4 cup chopped fresh parsley (for garnish)
  • Extra grated Parmesan (for serving)

Instructions

  1. Peel Yukon Gold potatoes and slice into thin rounds (about 1/8-inch thick) using a mandoline or sharp knife.
  2. Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish generously with butter.
  3. In a medium saucepan over medium heat, melt 3 tbsp unsalted butter. Add minced garlic and cook for about 1 minute, stirring, until fragrant but not browned.
  4. Pour in heavy cream and chicken broth. Whisk to combine, then add grated Parmesan, sour cream, salt, black pepper, and thyme.
  5. Continue whisking until cheese melts and sauce is smooth (about 2-3 minutes). If sauce is too thick, add a splash more broth. Taste and adjust seasoning.
  6. Arrange half the potato slices in the baking dish, overlapping slightly. Pour half the garlic cream sauce over the first layer and spread evenly.
  7. Layer remaining potatoes on top and pour the rest of the sauce over. Use a spatula to gently press down so sauce coats all slices.
  8. Cover dish tightly with foil and bake for 30 minutes.
  9. Remove foil and bake uncovered for another 15-20 minutes, until top is golden and bubbling. For extra browning, broil for 2-3 minutes, watching closely.
  10. Let cool for 5-10 minutes before serving. Sprinkle with chopped parsley and extra Parmesan. Potatoes should be fork-tender and sauce creamy but not runny.

Notes

For best results, use freshly grated Parmesan and thin, even potato slices. You can make this dish vegetarian by swapping chicken broth for vegetable broth. For dairy-free, use plant-based cream, butter, and cheese. Let the dish rest before serving for a creamier sauce. Leftovers reheat well and flavors deepen overnight. For extra crispy edges, use a metal pan.
