Ingredients
- 5–6 medium potatoes, thinly sliced

- 1 cup heavy cream or milk
- 2 tablespoons butter, melted
- 1 teaspoon garlic powder
- 1 teaspoon salt
- ½ teaspoon black pepper
- Optional: chopped parsley or green onions for garnish
Instructions
- Prep the slow cooker
Lightly grease the inside of your slow cooker with butter or cooking spray. - Layer the ingredients
Add a layer of sliced potatoes at the bottom, followed by a layer of onions. Sprinkle some cheese, salt, pepper, and garlic powder. - Repeat layers
Continue layering potatoes, onions, and seasoning until all ingredients are used, finishing with cheese on top. - Add liquids
Pour the cream (or milk) evenly over the layers, then drizzle melted butter on top. - Cook
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until the potatoes are tender. - Serve
Let it sit for 10–15 minutes before serving. Garnish if desired.
Description
This dish is creamy, cheesy, and melt-in-your-mouth tender. The potatoes absorb all the flavors from the onions, butter, and cream, creating a rich and satisfying texture. It’s similar to scalloped potatoes but even easier thanks to the slow cooker.
Tips
- Slice potatoes evenly so they cook at the same rate.
- Use starchy potatoes (like Russet) for a softer texture, or waxy ones (like Yukon Gold) for a firmer bite.
- Add cooked bacon or ham for extra flavor.
- For a golden top, transfer to an oven-safe dish and broil for a few minutes after cooking.
- Don’t overfill the slow cooker—leave a little space at the top for even cooking.
Correction / Common Mistakes
- Undercooked potatoes: This usually happens if slices are too thick—keep them thin (about ⅛ inch).
- Too watery: Avoid adding too much liquid; potatoes release moisture as they cook.
- Lack of seasoning: Season each layer to ensure balanced flavor throughout.
