Step-by-Step Instructions
  1. Preheat your oven to 375°F (190°C). Gather ingredients and prepare your baking dish.
  2. Melt 2 tablespoons of butter and 2 tablespoons of olive oil in a skillet over medium heat. Add sliced onions and sauté for 15–20 minutes until caramelized.
  3. Add minced garlic for the last 2 minutes of sautéing. Stir until fragrant.
  4. In a mixing bowl, combine heavy cream, beef broth, Worcestershire sauce, dried thyme, salt, and black pepper. Whisk until smooth.
  5. Grease a 9x13-inch baking dish. Layer the sliced potatoes and onions tightly, finishing with a top layer of potatoes.
  6. Pour the cream mixture evenly over the layered potatoes and onions.
  7. Cover the dish tightly with aluminum foil and bake for 45 minutes.
  8. Remove the foil and sprinkle Gruyere and Parmesan cheese on top. Bake uncovered for an additional 15–20 minutes until golden brown.
