Ingredients:
– 1.5 kg (about 3 lbs) of potatoes, peeled and thinly sliced
– 1 cup heavy cream
– 1 cup milk
– 2 tablespoons all-purpose flour
– 1 teaspoon salt
– 1/2 teaspoon black pepper
– 1/2 teaspoon garlic powder
– 1/2 teaspoon onion powder
– 1/4 teaspoon paprika
– 1 cup shredded cheddar cheese
– 1/2 cup grated Parmesan cheese
– 1 tablespoon unsalted butter, cut into small pieces
Directions:
1. Start by greasing the inside of your slow cooker lightly with butter or non-stick cooking spray.
2. In a medium-sized mixing bowl, whisk together heavy cream, milk, flour, salt, pepper, garlic powder, and onion powder until smooth. This mixture will create the rich, savory sauce that the potatoes will cook in.
3. Place a layer of the thinly sliced potatoes in the bottom of the slow cooker. Pour a portion of the cream mixture over the potatoes and then sprinkle with some of the cheddar cheese and Parmesan.
4. Continue layering the potatoes, cream mixture, and cheeses until all ingredients are used, finishing with a layer of cheese.
5. Dot the top with the cut-up butter pieces and sprinkle with paprika for a hint of color and a little smoky flavor.
6. Cover the slow cooker and cook on low for 6 to 8 hours, or on high for 3 to 4 hours, until the potatoes are tender.
7. Once the potatoes have fully cooked and are tender, let them rest for a few minutes before serving. This allows the sauce to thicken slightly and the flavors to meld together perfectly.
