Recipe Information
Ingredients
- 6 medium potatoes
- 2 large yellow onion
- 4 tablespoons butter
- 1 cup heavy cream
- 1.5 cups shredded cheddar cheese
- 1 teaspoon garlic powder
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 2 tablespoons chopped fresh parsley
Instructions
Preheat your oven to 375°F (190°C).
Peel the potatoes and slice them thinly, about 1/8 inch thick. Use a mandoline slicer if available for consistent thickness.
Peel and slice the onions into thin rings.
In a large skillet over medium heat, melt 2 tablespoons of butter. Add the sliced onions and cook, stirring frequently, until they caramelize and turn golden brown, about 10-12 minutes. Set aside.
Grease a 9x13-inch baking dish with 1 tablespoon of butter.
Layer half of the potato slices evenly in the baking dish. Sprinkle with half the salt, half the pepper, and half the garlic powder.
Top the potatoes with half of the caramelized onions and 1/2 cup of shredded cheddar cheese.
Repeat the layering process with the remaining potatoes, seasonings, onions, and 1/2 cup shredded cheddar cheese.
Pour the heavy cream evenly over the entire dish.
Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes.
Remove the foil, sprinkle the remaining 1/2 cup of shredded cheddar cheese on top, and bake for an additional 10 minutes or until the cheese is bubbly and golden.
Remove from the oven and let the dish cool for 5 minutes. Garnish with freshly chopped parsley before serving.
