Ingredients

Potatoes

  • 6 medium-sized potatoes, peeled and thinly sliced

Sauce Mixture

  • 1 packet French onion soup mix
  • 2 cups sour cream
  • 1/4 cup milk
  • 1/2 cup butter, melted

Toppings

  • 2 cups shredded cheddar cheese
  • Salt and pepper to taste

Instructions

  1. Preheat Oven: Preheat the oven to 350°F (175°C) to ensure the dish cooks evenly.
  2. Prepare Baking Dish: Grease a 9×13-inch baking dish with butter or non-stick spray to prevent sticking.
  3. Mix Sauce: In a large bowl, combine the sour cream, milk, melted butter, and French onion soup mix. Stir well until all ingredients are fully blended.
  4. Layer Potatoes: Arrange the thinly sliced potatoes evenly in the greased baking dish, creating a single or slightly overlapping layer.
  5. Add Sauce Mixture: Pour the prepared sour cream and onion soup mixture evenly over the layered potatoes, ensuring all slices are coated.
  6. Bake Covered: Cover the dish tightly with aluminum foil and bake for 45 minutes, allowing the potatoes to cook and absorb flavors.
  7. Add Cheese: Remove the foil carefully, then sprinkle the shredded cheddar cheese evenly on top of the potatoes.
  8. Bake Uncovered: Return the dish to the oven uncovered and bake for an additional 15 minutes, until the cheese is bubbly and golden brown.
  9. Cool and Serve: Let the dish cool slightly for a few minutes before serving to allow it to set and to prevent burns.

Notes

  • For best results, use starchy potatoes like Russets for a creamier texture.
  • You can substitute sour cream with Greek yogurt for a tangier flavor and lighter option.
  • Add chopped fresh herbs like thyme or parsley for extra freshness.
  • Adjust salt and pepper to taste; the soup mix typically contains salt.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven.
