These creamy, cheesy scalloped potatoes are layered with a rich sauce and baked until golden and bubbly. Perfect for holidays, Sunday dinners, or any special occasion.
Ingredients
-
2 lbs potatoes (Yukon Gold or Russet), peeled and thinly sliced
-
2 tablespoons unsalted butter
-
1 small onion, finely diced
-
3 cloves garlic, minced
-
2 tablespoons all-purpose flour
-
2 cups whole milk (or 1 cup milk + 1 cup heavy cream for richer sauce)
-
1½ cups shredded cheddar cheese, divided
-
½ cup shredded mozzarella or Gruyère
-
1 teaspoon salt
-
½ teaspoon black pepper
-
¼ teaspoon paprika (optional)
-
2 tablespoons chopped fresh parsley (optional garnish)
Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter.
Step 2: Prepare the Potatoes
Peel the potatoes and slice them into thin rounds, about ⅛ inch thick. A mandoline slicer works well for even, consistent slices. Set aside.
Step 3: Make the Cream Sauce
In a medium saucepan, melt the butter over medium heat. Add the diced onion and cook for 3 to 4 minutes until softened. Stir in the garlic and cook for another 30 seconds until fragrant.
Sprinkle in the flour and whisk continuously for 1 minute to form a roux. Slowly pour in the milk, whisking constantly to avoid lumps. Cook until the sauce thickens slightly, about 3 to 5 minutes. Stir in 1 cup of the shredded cheddar cheese, salt, pepper, and paprika. Stir until the cheese is melted and the sauce is smooth.
Step 4: Assemble the Dish
Arrange half of the potato slices in the prepared baking dish, overlapping slightly. Pour half of the sauce evenly over the potatoes. Repeat with the remaining potatoes and sauce.
Step 5: Add Cheese Topping
Sprinkle the remaining ½ cup of cheddar cheese and the mozzarella (or Gruyère) evenly over the top.
Step 6: Bake
Cover the dish with foil and bake for 40 minutes. Remove the foil and bake for an additional 15 to 25 minutes, until the potatoes are tender when pierced with a knife and the top is golden and bubbly.
Step 7: Rest and Serve
Let the dish rest for 10 minutes before serving. This allows the sauce to thicken and makes serving easier. Garnish with fresh parsley if desired.
Tips for Perfect Scalloped Potatoes
-
Slice Potatoes Evenly: Uniform slices ensure even cooking. A mandoline slicer is highly recommended for consistent thickness.
-
Use Yukon Gold or Russet Potatoes:Yukon Golds have a buttery flavor and hold their shape well. Russets are starchy and create a creamier texture.
-
Do Not Overcrowd the Pan: Arrange the potato slices in a single layer with slight overlapping. Too many layers can cause uneven cooking.
-
Make a Smooth Sauce: Whisk constantly when adding the milk to prevent lumps. A smooth roux is the foundation of a creamy sauce.
-
Cover with Foil: Covering for the first part of baking ensures the potatoes cook through without the top burning.
-
Let It Rest: Allowing the dish to rest after baking helps the sauce thicken and set, making for cleaner servings.
Variations and Additions
-
Ham and Cheese Scalloped Potatoes: Add 1 cup of diced cooked ham between the layers.
-
Bacon Scalloped Potatoes: Sprinkle cooked, crumbled bacon over the top before baking.
-
Herbed Scalloped Potatoes: Add 1 teaspoon of dried thyme or rosemary to the sauce.
-
Gruyère and Parmesan: Substitute Gruyère for mozzarella and add ¼ cup of grated Parmesan to the topping.
-
Leek and Potato: Sauté 1 cup of sliced leeks with the onion for a delicate, sweet flavor.
-
Spicy Version: Add a pinch of cayenne pepper or red pepper flakes to the sauce.
What to Serve with Scalloped Potatoes
These creamy, cheesy potatoes pair beautifully with:
-
Roasted Chicken or Turkey: A classic holiday pairing.
-
Ham: The perfect companion for baked ham.
-
Steak or Prime Rib: A decadent side for special dinners.
-
Roasted Vegetables: Serve alongside green beans, Brussels sprouts, or asparagus.
-
Simple Salad: A crisp green salad balances the richness.
Storage and Reheating
-
Refrigerator: Store leftovers in an airtight container in the refrigerator for up to 4 days.
-
Reheating: Reheat in a 350°F oven covered with foil for 15 to 20 minutes, or until warmed through. Individual portions can be reheated in the microwave.
-
Freezer: Scalloped potatoes can be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating. Note that the texture may soften slightly.
Why This Recipe Works
This recipe succeeds because of its classic technique and balance of flavors. The roux-based sauce ensures a smooth, creamy consistency that coats every potato slice. Layering the potatoes and sauce allows the flavors to meld as they bake, while covering the dish first ensures the potatoes cook through before the top browns.
The combination of cheddar and mozzarella provides both sharpness and a beautiful, melty texture. Letting the dish rest after baking allows the sauce to thicken, resulting in perfectly sliceable portions.
