Ingredients
Scale
Sauce Ingredients
- 1 1/2 cups heavy cream (or half and half)
- 4 cloves garlic, minced
- 1/2 teaspoon dried thyme
- 1/2 teaspoon dried rosemary
- 1/2 teaspoon dried basil
- 1/4 teaspoon nutmeg
Main Ingredients
- 2 pounds russet potatoes, peeled and cut into 1/8-inch thick slices
- Kosher salt, to taste
- Freshly ground black pepper, to taste
- 1 cup shredded Gruyere cheese
- 1 cup shredded cheddar cheese
- 1/4 cup freshly grated Parmesan cheese
- 1/2 teaspoon fresh rosemary, chopped
- Chopped parsley, for garnish
Instructions
- Make the sauce: In a medium saucepan, whisk together heavy cream, minced garlic, dried thyme, dried rosemary, dried basil, and nutmeg. Heat the mixture over medium heat for about 1-2 minutes until warmed through and fragrant.
- Layer the potatoes: Arrange a layer of the thinly sliced potatoes in an overlapping pattern inside a 4-quart slow cooker. Season the layer with kosher salt and freshly ground black pepper to taste.
- Add creamy sauce and cheese: Pour approximately 1/3 cup of the cream mixture evenly over the potatoes and sprinkle with a portion of the shredded Gruyere and cheddar cheese. Repeat this layering process two more times, finishing with cream and cheese layers.
- Cover and cook: Cover the slow cooker with its lid and cook on the high setting for 4 to 5 hours, or until the potatoes are tender when pierced with a fork.
- Sprinkle with Parmesan: Once the potatoes are fully cooked, sprinkle the freshly grated Parmesan cheese evenly on top. Cover again and continue cooking for an additional 5 to 10 minutes until the Parmesan melts and forms a slightly golden crust.
- Uncover and rest: Remove the lid and let the scalloped potatoes rest in the slow cooker for 15 minutes to allow the dish to set and cool slightly for easier serving.
- Garnish and serve: Garnish the top with freshly chopped parsley and chopped fresh rosemary before serving to add color and fresh herbal flavor.
Notes
- For a lighter alternative, substitute half and half for heavy cream.
- Use a mandoline slicer to get evenly thin potato slices for consistent cooking.
- Low and slow cook on low setting may require 6-7 hours instead of 4-5 hours on high.
- Make sure the slow cooker insert is at least 4 quarts to accommodate the layers.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
- Reheat covered in the oven at 350°F (175°C) until warmed through, about 20 minutes.
