Scalloped Potatoes vs. Potatoes Au Gratin: What’s the Difference?

Before we dive into the recipe, let’s clear up a common confusion. Many people use these terms interchangeably, but there’s a distinction:

Scalloped Potatoes traditionally feature a simple cream sauce and no cheese. They’re all about the creamy, onion-flavored sauce .

Potatoes Au Gratin include cheese, creating that signature golden, bubbly topping .

This recipe is technically Potatoes Au Gratin—but in most American kitchens, “Cheesy Scalloped Potatoes” is the more familiar term. Whatever you call them, they’re absolutely delicious .

Ingredients for Perfect Cheesy Scalloped Potatoes

Here’s everything you’ll need for this classic, comforting dish.

For the Potatoes:

· 2½ to 3 pounds Yukon Gold potatoes (about 5-6 medium potatoes)
· 2 tablespoons butter, softened (for greasing the dish)

For the Creamy Cheese Sauce:

· 4 tablespoons unsalted butter
· 1 small onion, finely chopped (or 2 shallots)
· 3 cloves garlic, minced
· ¼ cup all-purpose flour
· 2 cups whole milk, warmed
· 1 cup heavy cream (or half-and-half for a lighter version)
· 1 teaspoon salt
· ½ teaspoon black pepper
· ½ teaspoon dried thyme (or 1 teaspoon fresh)
· ¼ teaspoon nutmeg (optional but amazing)
· 2 cups shredded sharp cheddar cheese, divided
· 1 cup grated Parmesan cheese, divided

For the Topping:

· 2 tablespoons butter, melted
· ½ cup panko breadcrumbs (optional, for extra crunch)
· Fresh parsley, chopped, for garnish

Ingredient Notes and Substitutions

Potatoes: Yukon Gold potatoes are ideal. They have a buttery flavor, creamy texture, and hold their shape well . Russets work too but are starchier and may break down more. Red potatoes can be used but have a waxier texture .

Cheese: Sharp cheddar provides the most flavor. Gruyère is classic for au gratin potatoes and adds nutty complexity. A mix of cheddar and Parmesan is my favorite combination .

Milk and Cream: Whole milk and heavy cream create the richest sauce. For a lighter version, use all half-and-half or whole milk with an extra tablespoon of flour .

Thyme: Fresh or dried thyme adds earthy notes that complement the cheese. You can also use rosemary or a blend of herbs de Provence .

Step-by-Step Instructions

Follow these steps for perfectly creamy, cheesy scalloped potatoes.

Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C) . Generously butter a 9×13-inch baking dish (or a 3-quart casserole dish) with the 2 tablespoons softened butter .

Step 2: Slice the Potatoes

1. Peel the potatoes if desired (Yukon Golds have thin skins that are fine to leave on) .
2. Using a sharp knife, mandoline, or food processor slicing disc, cut the potatoes into ⅛-inch thick slices . Uniform thickness is crucial for even cooking .
3. Place the sliced potatoes in a large bowl of cold water to prevent browning while you prepare the sauce . Drain and pat dry before using.

Step 3: Make the Cheese Sauce

1. In a large saucepan, melt the 4 tablespoons butter over medium heat.
2. Add the chopped onion and cook until softened, about 3-4 minutes .
3. Add the minced garlic and cook for another minute until fragrant .
4. Sprinkle the flour over the onion mixture and whisk constantly for 1-2 minutes to cook out the raw flour taste .
5. Gradually whisk in the warmed milk and heavy cream, stirring constantly to prevent lumps .
6. Continue cooking, stirring frequently, until the sauce thickens enough to coat the back of a spoon, about 5-7 minutes .
7. Remove from heat and stir in salt, pepper, thyme, nutmeg (if using), 1½ cups of the cheddar cheese, and ½ cup of the Parmesan cheese. Stir until the cheese is melted and the sauce is smooth .
8. Taste and adjust seasoning as needed.

Step 4: Layer the Potatoes

1. Drain the potato slices and pat them dry with a clean kitchen towel or paper towels .
2. Arrange a single layer of potato slices in the bottom of the prepared baking dish, slightly overlapping .
3. Pour about ⅓ of the cheese sauce over the potatoes, spreading to cover evenly .
4. Repeat layers two more times, ending with a final layer of sauce on top .

Step 5: Add the Topping

1. In a small bowl, mix the remaining ½ cup cheddar cheese and ½ cup Parmesan cheese .
2. Sprinkle the cheese mixture evenly over the top layer of sauce .
3. If using breadcrumbs, mix the panko with the 2 tablespoons melted butter and sprinkle over the cheese .

Step 6: Bake

1. Cover the baking dish with aluminum foil and bake for 45 minutes .
2. Remove the foil and bake for another 20-30 minutes, until the potatoes are tender when pierced with a knife and the top is golden brown and bubbly .
3. If the top is browning too quickly, cover loosely with foil for the remaining time.

Step 7: Rest and Serve

1. Let the potatoes rest for 10-15 minutes before serving. This allows the sauce to set and makes serving easier .
2. Garnish with fresh parsley and serve warm.

Pro Tips for the Best Cheesy Scalloped Potatoes

1. Use a Mandoline for Even Slices

Uniform thickness is essential for even cooking. A mandoline makes quick work of slicing and ensures all your potatoes are the same thickness .

2. Don’t Skip the Resting Time

The potatoes need time to set after baking. If you serve them immediately, the sauce will be runny. Give them 10-15 minutes, and they’ll hold together beautifully .

3. Warm Your Milk and Cream

Adding cold liquid to the roux can create lumps. Warming the milk and cream ensures a smooth, velvety sauce .

4. Layer Carefully

Take your time with the layers. Arrange the potatoes in slightly overlapping rows for the most attractive presentation .

5. Test for Doneness

Potatoes are done when a knife inserted into the center meets no resistance. Don’t rely solely on time—test them .

6. Make Ahead for Easy Entertaining

Assemble the dish completely, cover, and refrigerate for up to 24 hours. Add 10-15 minutes to the covered baking time when cooking from cold .

7. Use Freshly Grated Cheese

Pre-shredded cheese contains anti-caking agents that can make the sauce grainy. Grate your own cheese for the smoothest, creamiest results .

Delicious Variations to Try

1. Classic Potatoes Au Gratin

Use Gruyère cheese instead of cheddar and add a pinch of nutmeg. This is the classic French version and absolutely divine .

2. Bacon and Cheddar Scalloped Potatoes

Add 6 slices of cooked, crumbled bacon between the layers. The smoky, salty bacon takes these potatoes over the top .

3. Garlic and Herb Scalloped Potatoes

Add an extra 3-4 cloves of roasted garlic to the sauce. Use fresh thyme, rosemary, and parsley for an herby twist .

4. Ham and Cheese Scalloped Potatoes

Layer diced ham between the potato layers. Perfect for using up holiday ham leftovers .

5. Loaded Baked Potato Style

Top the finished potatoes with crumbled bacon, extra cheddar cheese, and chopped chives. Serve with sour cream on the side .

6. Truffle Scalloped Potatoes

Add a drizzle of truffle oil to the sauce and use a mix of Gruyère and Parmesan. These are incredibly elegant and special .

7. Slow Cooker Version

Layer potatoes and sauce in a slow cooker, cover, and cook on LOW for 6-7 hours or HIGH for 3-4 hours. Top with cheese during the last 30 minutes .

Storage and Reheating

Refrigerator Storage

Store leftover scalloped potatoes in an airtight container in the refrigerator for up to 4 days .

Freezer Instructions

1. Cool completely.
2. Wrap tightly in plastic wrap, then foil, or transfer to a freezer-safe container.
3. Thaw overnight in the refrigerator before reheating.

Reheating Instructions
