Description

Golden Potato and Butternut Squash is a creamy, comforting baked dish that layers tender slices of potatoes and sweet squash in a savory herb-infused cheese sauce. Perfect for holiday spreads or hearty weeknight dinners.


Ingredients

Units Scale
  • 1.5 lbs golden potatoes (Yukon Gold), peeled and thinly sliced
  • 1.5 lbs butternut squash, peeled and thinly sliced
  • 1 cup heavy cream
  • 1 cup milk
  • 2 garlic cloves, minced
  • 1 teaspoon fresh thyme
  • 1/8 teaspoon ground nutmeg
  • Salt and pepper to taste
  • 1 1/2 cups grated Gruyère cheese (or a blend with Parmesan)
  • 1 tablespoon butter (for greasing and topping)

Instructions

  1. Preheat oven to 375°F (190°C) and butter a large baking dish.
  2. Thinly slice potatoes and butternut squash using a mandoline or sharp knife for uniform slices.
  3. In a saucepan, heat cream, milk, garlic, thyme, nutmeg, salt, and pepper over low heat until just warm. Do not boil. Remove from heat.
  4. Layer half of the potatoes in the bottom of the baking dish, overlapping slightly. Add a layer of butternut squash over the potatoes.
  5. Pour half of the warm cream mixture over the layers. Sprinkle with half of the cheese.
  6. Repeat with remaining potatoes and squash. Pour over the rest of the cream and top with remaining cheese.
  7. Dot with butter and cover the dish with foil.
  8. Bake for 40 minutes covered, then uncover and bake an additional 25–30 minutes until golden and bubbling.
  9. Let rest for 10 minutes before serving to allow the gratin to set.

Notes

  • Use a mandoline slicer for evenly thin slices and consistent cooking.
  • Add caramelized onions or crumbled bacon for extra depth and flavor.
  • Vegan version: Use plant-based cream, non-dairy milk, and vegan cheese.
  • Swap thyme for rosemary or sage to change the flavor profile.
  • This dish pairs well with poultry, pork, or as a vegetarian centerpiece.
