Scale
Potato Mixture:
- 2 lbs Yukon gold potatoes, thinly sliced
- 1 packet (1 oz) French onion soup mix
- ½ cup sour cream
- ¼ cup milk
- ½ teaspoon garlic powder
- Salt and black pepper to taste
Caramelized Onions:
- 2 tablespoons olive oil

Additional Ingredients:

- 2 tablespoons fresh parsley, chopped (optional)
Instructions
- Preheat the Oven: Preheat the oven to 375°F (190°C) and grease a 9×13-inch baking dish.
- Caramelize Onions: In a large skillet, heat olive oil over medium heat. Add sliced onions and cook until golden and caramelized, about 15–20 minutes.
