How to Make Slow Cooker Scalloped Potatoes
Step 1: Prepare the Slow Cooker
Lightly grease the inside of your slow cooker with butter or non-stick cooking spray.
Step 2: Make the Cream Sauce
In a medium mixing bowl, whisk together 1 cup heavy cream, 1 cup milk, 2 tablespoons flour, 1 teaspoon salt, 1/2 teaspoon black pepper, 1/2 teaspoon garlic powder, and 1/2 teaspoon onion powder until smooth. Set aside.
Step 3: Layer Potatoes and Cheese
- Place a layer of thinly sliced potatoes in the slow cooker.
- Pour a portion of the cream sauce over the potatoes.
- Sprinkle some shredded cheddar and grated Parmesan over the top.
- Repeat layers until all potatoes, cream sauce, and cheese are used, finishing with a layer of cheese.
Step 4: Add Butter and Paprika
Dot the top layer with small pieces of 1 tablespoon unsalted butter. Sprinkle 1/4 teaspoon paprika over the top for color and subtle flavor.
Step 5: Slow Cook the Potatoes
Cover and cook on LOW for 6–8 hours or on HIGH for 3–4 hours, until the potatoes are fork-tender and the sauce is creamy.
Step 6: Rest and Serve
Allow the scalloped potatoes to rest for 5–10 minutes before serving. This helps the sauce thicken slightly and allows the flavors to meld beautifully.
Chef’s Tips
- For extra flavor, stir in a teaspoon of Dijon mustard or a pinch of nutmeg into the cream sauce.
- Layering thinly ensures even cooking; a mandoline slicer can make slicing quick and consistent.
- For a golden top, you can briefly place the slow cooker insert under a broiler for 2–3 minutes before serving.
These Slow Cooker Scalloped Potatoes are a hassle-free, comforting side dish that pairs perfectly with roasted meats, poultry, or a holiday feast.
