Ingredients
Potatoes
- 2½–3 lb (1.1–1.4 kg) Yukon Gold or russet potatoes, peeled and thinly sliced (⅛ inch)
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
Cream Sauce
- 2 cups heavy cream
- 1 cup sour cream
- ½ cup chicken broth
- 1 packet (1 oz) ranch seasoning mix (or 2 tablespoons homemade ranch seasoning)
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried parsley
- ½ teaspoon dried thyme
- ½ teaspoon black pepper
- ¼ teaspoon paprika
- 2 tablespoons melted butter
Topping
- 1 cup shredded cheddar cheese
- ¼ cup grated Parmesan cheese
- Fresh parsley, chopped
Instructions
- Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray.
- Arrange half of the sliced potatoes in the baking dish. Sprinkle with half of the diced onion, garlic, mozzarella, and Parmesan.
- Add the remaining potatoes and sprinkle with the rest of the onion and garlic.
- In a large bowl or measuring jug, whisk together:
- Heavy cream
- Sour cream
- Chicken broth
- Ranch seasoning
- Garlic powder
- Onion powder
- Dried parsley
- Thyme
- Pepper
- Paprika
- Melted butter
- Pour the cream mixture evenly over the potatoes, making sure it seeps between the layers.
- Cover tightly with foil and bake for 50 minutes.
- Remove the foil, sprinkle with the cheddar and Parmesan cheeses, and bake uncovered for 20–25 minutes, until the potatoes are fork-tender and the top is golden and bubbly.
- Let the dish rest for 10–15 minutes before serving to allow the sauce to thicken.
