What Are Scalloped Potatoes?

Scalloped potatoes are a classic side dish made with thinly sliced potatoes baked or slow cooked in a creamy sauce. So by definition these are probably actually au gratin potatoes, because traditional scalloped potatoes typically do not include cheese, but these one have cheese!

This crockpot version keeps the classic creamy texture while making it easier to prepare. And adding cheese.

Ingredients for Crockpot Scalloped Potatoes

3 pounds Yukon Gold or Russet potatoes, thinly sliced
1 medium yellow onion, thinly sliced
3 tablespoons butter
3 tablespoons all-purpose flour
2 cups milk
1 cup heavy cream
3 cloves garlic, minced
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon dried thyme
½ teaspoon onion powder
1 cup shredded cheddar cheese
½ cup grated Parmesan cheese
Fresh parsley or chives for garnish

How to Make Crockpot Scalloped Potatoes

Step 1: Prepare the Potatoes

Wash and thinly slice the potatoes into even slices, about ⅛-inch thick.

A mandoline slicer works great for getting uniform slices, which helps the potatoes cook evenly.

Step 2: Make the Creamy Sauce

In a saucepan over medium heat, melt butter.

Whisk in flour and cook for 1 minute.

Slowly whisk in milk and heavy cream until smooth. Add garlic, salt, pepper, thyme, and onion powder.

Continue cooking until the sauce begins to slightly thicken.

Step 3: Layer in the Crockpot

Lightly grease the inside of your slow cooker.

Add a layer of sliced potatoes, followed by onions and a little sauce.

Repeat layers until all ingredients are used.

If adding cheese, sprinkle it between layers or on top.

Step 4: Slow Cook

Cover and cook until the potatoes are tender.

Cook:

LOW: 5–6 hours
HIGH: 3–4 hours

Avoid lifting the lid too often, as this releases heat and increases cooking time.

Step 5: Serve

Once the potatoes are fork tender, garnish with fresh herbs and serve warm.

Tips for the Best Slow Cooker Scalloped Potatoes

Slice Potatoes Evenly

Uniform slices cook at the same rate and help prevent some pieces from being undercooked while others become mushy.

Choose the Right Potato

Yukon Gold potatoes create a creamy texture, while Russet potatoes give a softer, more traditional scalloped potato texture.

Don’t Overcook

Potatoes can become too soft if cooked for too long. Check toward the end of the cooking time.

Add More Cheese at the End

If you prefer extra cheesy scalloped potatoes, top with additional cheese during the last 20–30 minutes for the best texture.

How to Store Leftover Scalloped Potatoes

Refrigerator: Store leftovers in an airtight container for up to 4 days.

Reheating: Warm individual portions in the microwave or reheat covered in the oven until warmed through. Add a splash of milk or cream if the sauce needs loosening.

Freezer: Scalloped potatoes can be frozen, but the creamy sauce texture may change slightly after thawing. For best results, freeze before baking and finish cooking when ready to serve.

Frequently Asked Questions

Can I put raw potatoes in the crockpot? Yes! Raw sliced potatoes cook beautifully in the slow cooker when layered with sauce and cooked until tender.

Can I make scalloped potatoes ahead of time? Yes. Prepare them up to a day ahead, refrigerate, and reheat before serving.

Why are my crockpot scalloped potatoes not creamy? Make sure your sauce is thickened before adding it to the crockpot. Also, avoid adding too much liquid, as potatoes release moisture as they cook.
