Ingredients You’ll Need
· 3 lbs Russet or Yukon Gold potatoes, peeled and thinly sliced (about 1/8-inch thick)
· 1 small yellow onion, finely diced
· 3 cloves garlic, minced
· 3 tablespoons unsalted butter
· 1 1/2 cups heavy cream
· 1/2 cup chicken broth
· 2 1/2 cups shredded sharp cheddar cheese, divided
· 1/2 cup grated Parmesan cheese
· 1 teaspoon salt
· 1/2 teaspoon black pepper
· 1/2 teaspoon smoked paprika
· Fresh parsley, chopped (for garnish)
Optional add-ins: 1 cup diced cooked ham, 1/2 cup cooked crumbled bacon, 1/4 teaspoon nutmeg, 1 teaspoon Dijon mustard, 1/2 teaspoon garlic powder, 1 cup caramelized onions, 1/2 cup Gruyère cheese for extra melt
Note: For a lighter version, use half-and-half instead of heavy cream and reduce butter. For a gluten-free version, ensure chicken broth is gluten-free. Russet potatoes break down slightly and create a creamier texture, while Yukon Gold hold their shape better. A mandoline slicer ensures uniform, thin slices for even cooking.
Step-by-Step Instructions
- Make the Cream Sauce: In a medium saucepan over medium heat, melt the butter. Add the diced onion and minced garlic, sautéing for 2-3 minutes until softened and fragrant. Don’t let the garlic burn.
- Add Liquids and Seasonings: Pour in the heavy cream and chicken broth. Stir in the salt, black pepper, and smoked paprika. Bring the mixture to a gentle simmer, then remove from heat. The sauce should be smooth and fragrant.
- Grease the Slow Cooker: Lightly grease the insert of your slow cooker with butter or non-stick cooking spray. Spread a thin layer of the cream mixture on the bottom to prevent sticking.
- Layer the Potatoes: Layer one-third of the sliced potatoes in the slow cooker. Top with one-third of the cream mixture and 1/2 cup of the shredded cheddar cheese. Repeat the layers two more times, finishing with the remaining cream mixture.
- Cook Low and Slow: Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours, until the potatoes are completely fork-tender. Avoid opening the lid during cooking to maintain consistent heat.
- Add the Final Cheese: During the final 20 minutes of cooking, sprinkle the remaining 1 cup of shredded cheddar cheese and the grated Parmesan cheese evenly over the top. Cover and let it melt completely.
- Broil for Golden Crust (Optional): For that golden-brown, bubbly crust, transfer the slow cooker insert (if oven-safe) to a broiler for 3-5 minutes, watching closely to prevent burning. Alternatively, use a kitchen torch to brown the top.
- Rest and Serve: Let the potatoes rest for 10 minutes before serving. This allows the sauce to thicken and the layers to set. Garnish with fresh chopped parsley and serve hot.
Tips for the Best Slow Cooker Cheesy Scalloped Potatoes
· Slice Potatoes Uniformly: Use a mandoline slicer for even 1/8-inch slices. Uniform slices ensure even cooking and a creamy texture.
· Layer Properly: Alternate potatoes, sauce, and cheese for even distribution of flavor in every bite.
· Don’t Skip the Saucepan Step: Sautéing the onions and garlic in butter and simmering the cream mixture adds depth of flavor that you can’t get from dumping ingredients directly into the slow cooker.
· Resist the Urge to Stir: Layering is key for scalloped potatoes. Stirring creates a mushy texture. Let the layers cook undisturbed.
· Check Doneness: Potatoes should be fork-tender. If they’re still firm after the minimum cooking time, continue cooking in 30-minute increments.
· Let It Rest: The 10-minute rest is essential. It allows the sauce to thicken and makes serving easier.
· Keep Warm: If serving at a party, keep the slow cooker on the “warm” setting and serve directly from it.
Variations & Substitutions
· Ham and Cheese Scalloped Potatoes: Add 1 cup diced cooked ham between the layers for a hearty main dish.
· Bacon Cheddar Scalloped Potatoes: Sprinkle 1/2 cup cooked crumbled bacon over the top with the final cheese.
· Gruyère and Thyme Version: Use Gruyère instead of cheddar and add 1 teaspoon fresh thyme for a French-inspired twist.
· Garlic Parmesan Version: Increase garlic to 6 cloves and use all Parmesan cheese for a garlicky, nutty flavor.
· Spicy Scalloped Potatoes: Add 1/4 teaspoon cayenne pepper or diced jalapeños to the cream sauce.
· Sweet Potato Version: Replace half the Russet potatoes with thinly sliced sweet potatoes for a colorful, slightly sweet variation.
Make-Ahead and Freezer Instructions
· Overnight Preparation: Assemble the entire dish in the slow cooker insert the night before. Cover and refrigerate. In the morning, place the insert in the slow cooker and cook as directed, adding 1 hour to the cooking time since it starts cold.
· Freezer Method: This dish can be frozen after cooking. Let it cool completely, transfer to a freezer-safe container, and freeze for up to 3 months. Thaw overnight in the refrigerator and reheat in the oven or microwave.
Frequently Asked Questions
Can I use a different type of potato?
Yes! Russet potatoes create a softer, creamier texture, while Yukon Gold hold their shape better. Red potatoes also work well. Avoid waxy potatoes like fingerlings, which don’t break down as nicely.
Do I have to peel the potatoes?
No! You can leave the skins on for a rustic texture and extra nutrients. Just scrub them well before slicing. Peeling creates a more classic, creamy texture.
Why are my potatoes still hard?
This usually means they weren’t sliced thin enough or the cooking time was too short. Use a mandoline for 1/8-inch slices and cook until fork-tender. Different slow cookers vary in temperature—add more time if needed.
Can I make this without heavy cream?
Yes! Use half-and-half or whole milk for a lighter version. The sauce will be slightly thinner but still delicious. You can also use evaporated milk for a creamier texture without as much fat.
How do I store leftovers?
Store in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or reheat the entire dish in a 350°F oven until hot.
Can I double this recipe?
Yes! Double all ingredients and use a larger slow cooker (6-8 quart). Increase cooking time by 1-2 hours on LOW. Check doneness at the minimum time.
Is this recipe gluten-free?
It can be. Ensure chicken broth is gluten-free and use all gluten-free ingredients. The recipe is naturally gluten-free if you use gluten-free broth.
What can I serve with scalloped potatoes?
Serve with roasted chicken, baked ham, meatloaf, grilled steak, or pork tenderloin. They’re also delicious alongside a holiday turkey or prime rib.
