Ingredients

Scale

Onion Caramelization

  • 2 tablespoons unsalted butter
  • 2 large yellow onions, thinly sliced
  • 1 teaspoon granulated sugar (optional, for faster caramelizing)
  • 1 tablespoon olive oil (optional, if onions look dry)
  • 1/2 teaspoon kosher salt (for onions)

Creamy Pour-Over Mixture

  • 2 cups heavy cream
  • 1 cup finely grated Parmesan cheese
  • 1 teaspoon kosher salt
  • 1 teaspoon freshly ground black pepper
  • 2 teaspoons fresh thyme leaves, chopped (or 1 teaspoon dried thyme)
  • Caramelized onions (from above step)

Potatoes and Assembly

  • 3 pounds russet or Yukon Gold potatoes, peeled if desired and thinly sliced (about 1/8-inch thick)
  • 1 tablespoon unsalted butter or cooking spray, for greasing the casserole dish
  • 2 tablespoons grated Parmesan cheese for topping

Instructions

  1. Preheat and Prepare Dish: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch glass casserole dish with 1 tablespoon unsalted butter or cooking spray and set aside.
  2. Caramelize the Onions: In a large skillet, melt 2 tablespoons butter over medium heat. Add sliced onions and 1/2 teaspoon kosher salt. Cook, stirring occasionally, for 20–25 minutes, reducing heat if they brown too quickly. If onions dry out or scorch, add 1 tablespoon olive oil and a splash of water. Optionally, add 1 teaspoon sugar to speed caramelization. Continue until onions are soft, golden brown, and fragrant. Remove from heat and let cool slightly.
  3. Make the Creamy Pour-Over Mixture: In a medium bowl or large measuring cup, whisk together 2 cups heavy cream, 1 cup grated Parmesan, 1 teaspoon kosher salt, black pepper, and chopped thyme. Stir in the warm caramelized onions until well combined. This creamy mixture will coat the potatoes.
  4. Prepare Potatoes: If desired, peel the potatoes. Slice them into thin, uniform 1/8-inch rounds using a sharp knife or mandoline to ensure even cooking.
  5. Layer Potatoes: Arrange potato slices evenly in the greased casserole dish, spreading them out to avoid clumping. Aim for one or two even layers to allow the cream to reach all slices.
  6. Pour Cream Mixture Over Potatoes: Give the creamy mixture a quick stir, then slowly pour it over the potatoes, ensuring onions and herbs distribute evenly. Gently shake the dish or use a spoon to nudge potatoes so cream seeps between slices.
  7. Add Topping and Cover: Sprinkle the remaining 2 tablespoons grated Parmesan cheese over the top. Cover the dish tightly with foil to retain moisture and promote steaming.
  8. Bake Until Tender: Place covered dish on the middle oven rack and bake for 45–55 minutes, until potatoes are fork-tender in the center.
  9. Brown the Top: Remove the foil and bake uncovered for an additional 15–20 minutes until the top is bubbly, lightly golden, and the edges are crisp and browned.
  10. Rest and Serve: Let the baked potatoes rest for at least 10 minutes before serving to allow the creamy sauce to thicken slightly. Serve warm and enjoy this rich, comforting dish.

Notes

  • Using a mandoline helps achieve evenly thin potato slices for uniform cooking.
  • Leaving the potato skins on adds texture and nutrients if you prefer.
  • The optional sugar in onions speeds caramelization but is not essential.
  • For extra flavor, you can add minced garlic to the caramelizing onions.
  • Covering with foil keeps moisture in and helps potatoes steam and cook evenly.
  • Letting the dish rest after baking helps the sauce thicken and makes serving easier.
  • Use fresh thyme if possible for the best herbal aroma.
