🥘Ingredients

For the Potatoes

3 pounds russet potatoes, peeled and thinly sliced (1/8 inch thick)
2 cups shredded sharp cheddar cheese
1 cup shredded Gruyere cheese
1/2 cup grated Parmesan cheese

For the Sauce

2 cups heavy cream
1 cup whole milk
3 tablespoons unsalted butter
3 tablespoons all-purpose flour
1 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon garlic powder
1/4 teaspoon paprika

👨‍🍳Directions

1Lightly grease the inside of a 6-quart slow cooker with butter or nonstick spray.
2In a large skillet over medium heat, melt the 3 tablespoons of butter.
3Whisk in the flour and cook for 1 minute, stirring constantly, until the mixture is bubbly and golden.
4Gradually whisk in the heavy cream and milk, stirring continuously to prevent lumps.
5Add the salt, pepper, garlic powder, and paprika.
6Continue cooking over medium heat for 3 to 4 minutes, until the sauce thickens enough to coat the back of a spoon.
7Remove the skillet from the heat and stir in 1 cup of the cheddar cheese, 1/2 cup of the Gruyere, and all of the Parmesan.
8Stir until the cheese is fully melted and the sauce is smooth.
Set aside.
9Layer one-third of the sliced potatoes evenly in the bottom of the slow cooker.
10Pour one-third of the cheese sauce over the potatoes, spreading it gently with a spatula.
11Sprinkle with a small handful of the remaining cheddar and Gruyere.
12Repeat the layering process two more times, using all the potatoes, sauce, and remaining shredded cheeses.
13Make sure the top layer is covered with sauce and cheese.
14Cover the slow cooker with the lid and cook on low heat for 4 to 5 hours, or on high heat for 2 to 3 hours.
15The potatoes are done when they are fork-tender and the edges are bubbly and golden.
16Let the dish rest, uncovered, for 10 minutes before serving to allow the sauce to set.

📝Notes

For best results, use a mandoline slicer to get even, thin potato slices. You can substitute half-and-half for the heavy cream for a lighter sauce. If your slow cooker runs hot, check the potatoes at the lower end of the cooking time to prevent overcooking.
