Slow Cooker Scalloped Potatoes
Introduction
Slow Cooker Scalloped Potatoes are the ultimate comfort food — thinly sliced potatoes layered with a rich, creamy cheese sauce that melts together into a luscious, savory masterpiece. Cooking them in a slow cooker makes this traditionally oven-baked dish nearly effortless, freeing up your oven while still delivering tender, golden perfection.
Perfect for holidays, potlucks, or cozy family dinners, this recipe turns humble potatoes into something indulgent, warm, and soul-satisfying.
Origin and Cultural Significance
Scalloped potatoes trace their roots to European peasant cooking, where simple, affordable ingredients — potatoes, milk, and butter — were baked together to stretch meals. The term “scalloped” likely comes from the Old English word collop, meaning “slices of meat,” which later evolved into referring to layered dishes.
In France, the dish’s close cousin is Gratin Dauphinois, which adds cream and sometimes cheese, creating the elegant French gratin that inspired American variations.
In the United States, scalloped potatoes became a beloved staple in home kitchens throughout the 20th century — a symbol of warmth, generosity, and family-centered meals. The slow cooker adaptation reflects modern cooking traditions: preserving classic flavors while embracing convenience.
Ingredients and Quantities
Serves 6–8 | Prep time: 20 minutes | Cook time: 4–5 hours (on high) or 6–7 hours (on low)
For the Scalloped Potatoes:
- 2 ½ pounds (1.1 kg) russet or Yukon Gold potatoes, peeled and thinly sliced
- 1 small onion, finely chopped (optional for flavor depth)
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups whole milk (or 1 cup milk + 1 cup cream for richer texture)
- 1 cup shredded sharp cheddar cheese
- ½ cup shredded mozzarella or Gruyère cheese (optional)
- ½ teaspoon garlic powder
- ½ teaspoon salt (adjust to taste)
- ¼ teaspoon black pepper
- ½ teaspoon dried thyme or parsley (optional for aroma)
- Nonstick cooking spray or butter, for greasing the slow cooker
Optional Additions
- Protein: Add diced ham, cooked bacon, or shredded chicken for a heartier meal.
- Vegetables: Layer with sliced mushrooms, spinach, or broccoli for extra nutrition.
- Cheese Swap: Try Monterey Jack, Parmesan, or Gruyère for a gourmet twist.
- Herbal Note: Add rosemary or chives for an aromatic finish.
- Topping: Sprinkle breadcrumbs or extra cheese during the last hour for a golden crust.
Tips for Success
- Slice evenly: Uniform slices (about ⅛-inch thick) ensure even cooking.
- Don’t skip the roux: The butter-flour base thickens the sauce perfectly.
- Grease the slow cooker: This prevents sticking and makes serving easier.
- Layer carefully: Start and end with potatoes for the best texture.
- Avoid curdling: Don’t add cold milk directly to the hot roux — whisk gradually.
- Rest before serving: Let the dish sit for 10–15 minutes to thicken naturally before plating.
Instructions
1. Prepare the Cheese Sauce:
- In a medium saucepan, melt butter over medium heat.
- Stir in flour and cook for 1 minute to form a roux.
- Gradually whisk in milk, stirring until smooth and thickened (about 5 minutes).
- Add garlic powder, salt, pepper, and half the cheese. Stir until melted and smooth. Remove from heat.
2. Layer the Potatoes:
- Lightly grease the slow cooker with butter or cooking spray.
- Layer half the sliced potatoes evenly on the bottom.
- Sprinkle with onions (if using) and pour half the sauce over the top.
- Add remaining potatoes and pour the rest of the sauce evenly over them.
- Sprinkle the remaining cheese on top.
3. Cook:
- Cover and cook on High for 4–5 hours or Low for 6–7 hours, until potatoes are fork-tender.
4. Finish:
- Turn off heat and let rest, covered, for 10–15 minutes before serving. This allows the sauce to set and thicken.
