Crockpot Scalloped Potatoes: The Ultimate Creamy, Cheesy Comfort Side

Tender, Thinly Sliced Potatoes Smothered in a Rich, Garlic-Herb Cheese Sauce — The Effortless "Dump-and-Go" Holiday or Weeknight Masterpiece

There is a specific, deeply comforting magic that happens when a pot of scalloped potatoes finishes cooking. The kitchen fills with the rich, savory aroma of melting cheese, toasted garlic, and earthy potatoes. It is the smell of family gatherings, Sunday roasts, and holidays spent with the people you love.

Enter the Crockpot Scalloped Potatoes.

While traditional scalloped potatoes require constant monitoring on the stovetop and precious oven space, this slow cooker version delivers all the creamy, cheesy, melt-in-your-mouth goodness with a fraction of the effort. By layering thinly sliced potatoes in a luscious, homemade garlic-cheddar sauce and letting the slow cooker do the heavy lifting, you get perfectly tender potatoes with a beautifully bubbly, golden cheese topping.

Best of all? It frees up your oven for the main course, making it the ultimate stress-free side dish for Thanksgiving, Christmas, or a cozy weeknight dinner.

🛒 Ingredients You’ll Need

The Potatoes

Ingredient	Amount	Pro Tips
Yukon Gold potatoes	3 lbs (about 6-8 medium)	Crucial: Yukon Golds hold their shape beautifully while becoming creamy. Russets work too but can break down more. Peel and slice thinly (⅛-inch thick).

The Rich Garlic-Cheddar Sauce

Ingredient	Amount	Pro Tips
Unsalted butter	4 tbsp (½ stick)	Provides a rich, savory base for the sauce.
Garlic	3 cloves, minced	Fresh is best for that aromatic depth.
All-purpose flour	¼ cup	Thickens the sauce so it clings to the potatoes rather than pooling at the bottom.
Chicken or vegetable broth	1 cup	Low-sodium is preferred so you can control the salt level.
Whole milk or half-and-half	1 cup	Half-and-half makes it richer; whole milk keeps it a bit lighter. Do not use skim milk.
Sour cream	½ cup	Adds a subtle tang and helps stabilize the dairy so it doesn't curdle in the slow cooker.
Sharp cheddar cheese	2 cups, freshly shredded	Divided: 1 ½ cups goes in the sauce, ½ cup goes on top. Shred it yourself for the best melt!
Seasonings	1 tsp salt, ½ tsp black pepper, ½ tsp smoked paprika, ½ tsp dried thyme	The paprika adds a beautiful color and subtle smokiness; thyme adds an earthy, classic note.
