Creamy, cheesy, tender potatoes made effortlessly in the slow cooker—perfect for holidays, Sunday dinners, and cozy family meals.
Crockpot Scalloped Potatoes are the kind of comforting side dish that makes any dinner feel special. Thinly sliced potatoes slowly cook in a rich, creamy sauce with plenty of melted cheese, creating tender layers with golden, bubbling edges.
The slow cooker also frees up valuable oven space, making this recipe especially useful when you’re preparing a large holiday meal. Similar slow-cooker versions commonly use Yukon Gold or russet potatoes, cream or milk, broth, and cheese, with cooking times generally around 3–6 hours depending on the cooker and potato thickness.

- 1 small yellow onion, thinly sliced
- 2 tablespoons unsalted butter
- 2 cloves garlic, minced
- ¾ teaspoon salt
- ½ teaspoon black pepper
For the Creamy Sauce
- 1½ cups heavy cream

- ¾ cup freshly grated Parmesan cheese

- ½ teaspoon garlic powder
- ¼ teaspoon paprika

This combination is inspired by several successful crockpot approaches that layer thin potatoes with cream, broth, Parmesan, and cheddar.
How to Make Crockpot Scalloped Potatoes
1. Prepare the Potatoes
Wash and peel the potatoes if desired. Slice them into thin, even rounds, approximately ⅛ to ¼ inch thick.
Keeping the slices similar in thickness is important because it helps them cook evenly. A mandoline can make this easier, but a sharp knife works perfectly well.
Place the sliced potatoes in a bowl of cold water while you prepare the remaining ingredients. Drain and pat them thoroughly dry before layering.
2. Prepare the Cream Sauce
In a medium bowl, whisk together:
- Heavy cream
- Chicken broth
- Garlic powder
- Paprika
- Thyme
- Salt
- Black pepper
Stir until everything is well combined.
For an especially rich version, you can gently warm the cream mixture before assembling the potatoes, but it isn’t absolutely necessary.
3. Prepare the Slow Cooker
Lightly grease the inside of a 6-quart slow cooker with butter or nonstick cooking spray.
Spread a small amount of the sliced onion across the bottom.
4. Start Layering
Arrange about one-third of the potatoes over the onions.
Pour approximately one-third of the cream mixture over the potatoes.
Sprinkle with some Parmesan and cheddar.
Repeat the layers two more times until all the potatoes, sauce, onions, and Parmesan have been used.
Try to finish with a layer of potatoes and sauce.
5. Add the Cheese
Sprinkle about 1 cup of the cheddar over the top.
Reserve the remaining ½ cup for the end of cooking. Adding some cheese later helps create a fresher, more melted topping instead of letting all of the cheese disappear into the sauce.
6. Cook
Cover the slow cooker with the lid.
Cook on HIGH for about 3–4 hours, or until the potatoes are completely fork-tender.
Cooking time can vary considerably between slow cookers, so begin checking around the 3-hour mark. Some recipes using similar thin potato slices recommend around 4 hours on HIGH, while other versions cook longer on LOW.
7. Finish With More Cheese
When the potatoes are tender, sprinkle the remaining cheddar over the top.
Cover for another 5–10 minutes, just until the cheese melts.
Turn off the slow cooker and let the potatoes rest uncovered for 10–20 minutes. This allows the creamy sauce to thicken and the layers to set.
Garnish with fresh parsley or thyme and serve warm.
Tips for the Best Crockpot Scalloped Potatoes
Slice the potatoes evenly
This is probably the most important tip. Thick slices can remain firm while thinner slices become overly soft.
Aim for approximately ⅛–¼ inch thickness.
Don’t skip drying the potatoes
If you soak the potatoes before cooking, dry them very well. Excess water can dilute the creamy sauce.
Use freshly grated cheese
Freshly grated cheddar and Parmesan generally melt more smoothly than many pre-shredded cheeses.
Don’t overcrowd the slow cooker
A 6-quart slow cooker works well for this quantity. The potatoes should be layered rather than packed into one huge pile.
Let them rest
Don’t immediately scoop out the potatoes when the cooking time ends. A short resting period allows the sauce to thicken.
Check the potatoes with a fork
The potatoes are ready when a fork slides easily through the center of the thickest slices.
Delicious Variations
Scalloped Potatoes With Ham
Add 1½–2 cups diced cooked ham between the potato layers. This turns the side dish into a much more substantial meal.
Garlic Herb Potatoes
Increase the garlic and add fresh rosemary, thyme, and parsley.
Bacon Cheddar Scalloped Potatoes
Cook and crumble 6–8 slices of bacon, then scatter it between the layers with the cheddar.
Loaded Scalloped Potatoes
Add cooked bacon, green onions, extra cheddar, and a little sour cream when serving.
Gruyère Scalloped Potatoes
Replace some or all of the cheddar with Gruyère for a richer, more sophisticated flavor. Gruyère is also commonly used in slow-cooker scalloped potato recipes.
Spicy Scalloped Potatoes
Add ¼–½ teaspoon cayenne pepper or a few sliced jalapeños to the layers.
What to Serve With Crockpot Scalloped Potatoes
These potatoes are incredibly versatile and pair especially well with roasted or grilled meats.
Try serving them with:
- Glazed ham
- Roast beef
- Prime rib
- Roast chicken
- Turkey
- Pork chops
- Grilled steak
- Meatloaf
- Green beans
- Roasted carrots
- Steamed broccoli
- Fresh garden salad
They’re particularly useful for holiday dinners because the slow cooker keeps the potatoes separate from the oven dishes.
Make-Ahead Instructions
You can prepare the potatoes and sauce several hours ahead.
For the best results, avoid leaving raw sliced potatoes sitting at room temperature for an extended period. Prepare the ingredients, cover them, and refrigerate until you’re ready to cook.
When possible, slice the potatoes relatively close to cooking time to minimize discoloration.
Storage
Allow leftover scalloped potatoes to cool, then transfer them to an airtight container and refrigerate.
They are best enjoyed within 3–4 days.
To reheat, warm individual portions in the microwave or reheat larger quantities gently in the oven until hot throughout.
If the sauce becomes thick after refrigeration, adding a small splash of milk or cream before reheating can help restore its creamy texture.
Frequently Asked Questions
Can I use russet potatoes?
Yes. Russet potatoes work very well and tend to produce a soft, creamy texture. Yukon Gold potatoes are another excellent choice and have a naturally buttery texture.
Can I use milk instead of heavy cream?
Yes. Whole milk will produce a lighter sauce, although it won’t be quite as rich. For a good middle ground, use half-and-half.
Why are my crockpot scalloped potatoes still hard?
The most common causes are potatoes that were sliced too thickly, uneven slices, or insufficient cooking time. Continue cooking until the thickest potato slices are completely fork-tender.
Can I cook them on LOW?
Yes. A LOW setting generally takes longer. Depending on the slow cooker and thickness of the potatoes, expect approximately 5–7 hours and begin checking for tenderness before serving. Slow-cooker recipes vary significantly in timing.
Are scalloped potatoes the same as au gratin potatoes?
They’re very similar, but traditionally scalloped potatoes are made primarily with a creamy sauce, while potatoes au gratin are more specifically associated with cheese. In modern recipes, however, the terms are often used interchangeably.
Final Thoughts
These Crockpot Scalloped Potatoes are creamy, cheesy, comforting, and wonderfully easy to prepare. Thin potato slices slowly cook in a flavorful cream sauce until tender, while cheddar and Parmesan create rich layers throughout the dish.
Whether you’re preparing Thanksgiving dinner, a Sunday roast, or simply want an easy comfort-food side, this slow-cooker version gives you delicious potatoes while keeping your oven free for everything else.
