Recipe Information
Ingredients
- 3 medium Red potatoes
- 3 medium Sweet potatoes
- 1 large Yellow onion
- 3 tablespoons Unsalted butter
- 2 tablespoons Olive oil
- 1 teaspoon Fresh thyme
- 2 cloves Garlic
- 1 teaspoon Salt
- 0.5 teaspoon Black pepper
- 0.5 cup Heavy cream
- 0.25 cup Parmesan cheese, grated
Instructions
Preheat the oven to 375°F (190°C) and grease a 9-inch baking dish with olive oil or butter.
Peel the red and sweet potatoes, then slice them into thin, uniform rounds about 1/8-inch thick using a knife or mandoline slicer.
Peel and thinly slice the yellow onion. Mince the garlic cloves and set them aside separately.
In a large skillet, heat 1 tablespoon of butter and 1 tablespoon of olive oil over medium heat. Add the sliced onion and cook, stirring frequently, for about 10-12 minutes, or until golden and caramelized. Reduce heat if necessary to prevent burning.
Add the minced garlic to the skillet with the caramelized onions and cook for an additional 1-2 minutes until fragrant. Remove from heat and set aside.
In a small bowl, stir together the heavy cream, fresh thyme, salt, pepper, and half of the grated Parmesan cheese. Set the mixture aside.
Arrange the potato slices in the greased baking dish, alternating between red and sweet potato slices in a spiral or overlapping pattern. Start from the outer edge and work your way to the center.
Pour the cream mixture evenly over the arranged potatoes, ensuring the liquid seeps between the layers.
Top the potatoes with the caramelized onions, spreading them evenly across the surface.
Sprinkle the remaining Parmesan cheese over the top.
Cover the dish with aluminum foil and bake in the preheated oven for 40 minutes.
After 40 minutes, remove the foil and dot the surface with the remaining 2 tablespoons of butter. Bake for an additional 15-20 minutes, or until the potatoes are tender and the top is golden brown.
Let the dish cool for 5 minutes before serving. Garnish with additional thyme if desired, and enjoy!
