Ingredients
Servings: 6
-
3 pounds russet potatoes, scrubbed and thinly sliced (about 1/8–1/4 inch)
-
2 cups heavy cream
-
1 1/2 cups finely grated Parmesan cheese, divided
-
1 1/2 teaspoons kosher salt (plus more to taste)
Ingredient Notes
Russet potatoes: Russet potatoes are starchy and become creamy during cooking. Leave the skins on for texture, or peel them if you prefer.
Heavy cream: Creates the rich, velvety sauce. Do not substitute with milk or half-and-half.
Parmesan cheese: Use finely grated Parmesan for the best texture and flavor.
Kosher salt: Seasons the potatoes evenly.
Step-by-Step Instructions
Step 1: Prepare the Slow Cooker
Lightly grease a 5- to 6-quart oval slow cooker insert with a thin film of butter or neutral oil.
Step 2: Slice the Potatoes
Scrub the potatoes well and pat them dry. Using a sharp knife or mandoline, slice the potatoes into thin, even rounds about 1/8–1/4 inch thick.
Step 3: Make the Cream Mixture
In a medium bowl, whisk together the heavy cream, 1 cup of the Parmesan cheese, and the kosher salt until smooth.
Step 4: Layer the Potatoes
Layer about one-third of the sliced potatoes in the bottom of the slow cooker, overlapping them slightly. Drizzle about one-third of the cream mixture evenly over the potatoes. Repeat the layering process two more times, finishing with a layer of potatoes on top.
Step 5: Slow Cook
Cover the slow cooker with the lid and cook on LOW for 4 1/2 to 5 1/2 hours. The potatoes are ready when they are very tender when pierced with a knife and the cream has thickened into a rich sauce.
Step 6: Add the Remaining Cheese
About 20 to 30 minutes before serving, remove the lid and sprinkle the remaining 1/2 cup of Parmesan cheese evenly over the top layer of potatoes. Recover and continue cooking until the cheese is melted and lightly golden.
Step 7: Rest and Serve
Turn the slow cooker to WARM and let the potatoes sit for 10 to 15 minutes before serving. This allows the sauce to thicken slightly.
