Ingredients List for Sunday Scalloped Potatoes

Sunday scalloped potatoes start with a short, simple list of ingredients that come together to create pure magic. You likely have most of these in your pantry right now.

• 3 pounds russet potatoes, peeled and thinly sliced (about 1/8-inch thick)
• 1 medium yellow onion, thinly sliced
• 3 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 2 cups whole milk
• 1 cup heavy cream
• 2 cloves garlic, minced
• 1 teaspoon dried thyme (or 1 tablespoon fresh)
• 1/2 teaspoon freshly grated nutmeg
• 1 1/2 teaspoons kosher salt, plus more for seasoning
• 1/2 teaspoon freshly ground black pepper
• 2 cups shredded sharp cheddar cheese, divided
• 1/2 cup grated Parmesan cheese

Smart Swaps: For a gluten-free version, swap the all-purpose flour for a 1:1 gluten-free blend. You can use half-and-half instead of heavy cream for a slightly lighter sauce, though it will be less rich. For a dairy-free take, use a rich, unsweetened plant-based milk and cream alternative, along with your favorite dairy-free cheeses. And if you’re dreaming of scalloped potatoes and ham, simply stir in 2 cups of diced cooked ham between the layers.

Timing for Your Sunday Scalloped Potatoes

• Prep Time: 25 minutes
• Cook Time: 1 hour 15 minutes
• Total Time: 1 hour 40 minutes

While this isn’t a 30-minute meal, the active prep is straightforward. The oven does the heavy lifting, transforming simple slices into a bubbling, cheesy masterpiece. I often prep the dish in the afternoon, cover it, and pop it in the oven an hour before we want to eat. That quiet baking time is a gift—it fills the house with the most incredible aroma.

Step-by-Step Instructions for Perfect Scalloped Potatoes

Making these cheesy scalloped potatoes is a gentle, rhythmic process. Follow these steps for a flawless, creamy result every time.

1. 
   

   Prep Your Pan and Potatoes. Preheat your oven to 375°F (190°C). Butter a 9×13 inch baking dish. Peel your potatoes and slice them uniformly thin—about 1/8-inch. A mandoline makes this quick and ensures even cooking, but a sharp knife and a steady hand work perfectly. Place the slices in a large bowl of cold water to prevent browning while you make the sauce.

   
   
2. 
   

   Build the Creamy Sauce. This is the heart of the dish. In a medium saucepan over medium heat, melt the butter. Whisk in the flour and cook for about 1 minute until it’s fragrant and golden. This is your roux—it will thicken the sauce beautifully. Slowly pour in the milk and cream, whisking constantly to prevent lumps. Add the garlic, thyme, nutmeg, salt, and pepper. Bring the mixture to a gentle simmer, whisking frequently, until it thickens enough to coat the back of a spoon, about 5-7 minutes. Remove from heat and stir in 1 cup of the cheddar cheese and all of the Parmesan until smooth.

   
   
3. 
   

   Layer with Care. Drain your potato slices and pat them dry with a clean kitchen towel. This step is key for a non-watery sauce! Arrange a single, slightly overlapping layer of potatoes in the bottom of your prepared dish. Scatter some of the sliced onions over the top. Ladle a portion of the cheese sauce over the layer, just enough to cover. Repeat the process—potatoes, onions, sauce—until all ingredients are used, ending with a final layer of sauce on top.

   
   
4. 
   

   Bake to Golden Perfection. Cover the dish tightly with aluminum foil and bake for 45 minutes. This covered time allows the potatoes to become tender in the steam. Then, remove the foil, sprinkle the remaining 1 cup of cheddar cheese over the top, and return the dish to the oven. Bake, uncovered, for another 25-30 minutes, or until the top is a gorgeous, spotted golden brown and the potatoes are fork-tender. Let the dish rest for 10-15 minutes before serving. This rest allows the sauce to set slightly, making serving much easier.

You don’t need any fancy tools. A 9×13 inch baking dish, a good saucepan, a whisk, a sharp knife or mandoline for slicing, and a mixing bowl are all you need. A box grater for the cheese is helpful, but pre-shredded works in a pinch.

Healthier Alternatives for the Recipe

You can tweak this classic to fit different dietary needs without losing its soul.

• Gluten-Free: Use a certified gluten-free all-purpose flour blend in the roux.
• Dairy-Free/Lighter: Substitute the milk and cream with an unsweetened, full-fat oat or cashew milk. Use vegan butter and your favorite meltable dairy-free cheeses. For a lighter sauce, use 3 cups of 2% milk and thicken it a bit longer, skipping the cream.
• Lower-Carb: While potatoes are the star, you can substitute half the potato slices with thinly sliced turnips or rutabaga for a similar texture with fewer net carbs.
• Higher-Protein: Stir in two cups of diced, cooked ham or turkey ham between layers. You can also use a sharp, aged white cheddar for more protein per ounce.

Serving Suggestions for Your Cozy Meal

These Sunday scalloped potatoes are a magnificent sidekick to a simple protein. I love serving them alongside my Sheet Pan Lemon Chicken or Creamy Dijon Chicken—the bright, tangy flavors cut through the richness of the potatoes perfectly. For a heartier, all-in-one meal, pair them with a green salad or some steamed green beans.

For a holiday spread, they’re a must next to a glazed ham or roast turkey. And don’t forget the leftovers! They reheat beautifully for a comforting lunch. If you love this style of cozy, cheesy baking, you might also enjoy my Cheesy Chicken Rice Bake.

Common Mistakes to Avoid with Scalloped Potatoes

1. Skipping the Roux: Don’t just pour milk over the potatoes. The flour-butter roux is essential for creating a stable, creamy sauce that won’t separate.
2. Not Drying the Potatoes: Wet potato slices will steam and water down your beautiful sauce. A quick pat-dry makes all the difference.
3. Slicing Too Thick: If your potato slices are more than 1/4-inch thick, they won’t cook through in the allotted time, leaving you with crunchy potatoes in a creamy sauce. Thin and even is the goal.
4. Skipping the Rest: Cutting into your cheesy scalloped potatoes right out of the oven is tempting, but it leads to a soupy mess on the plate. Letting it rest for 10-15 minutes allows the sauce to thicken and set.

Storing Tips for Sunday Scalloped Potatoes

• Leftovers: Cool completely, then store in an airtight container in the refrigerator for up to 4 days.
• Freezing: You can freeze baked scalloped potatoes. Portion into freezer-safe containers for up to 2 months. Thaw overnight in the fridge before reheating.
• Reheating: The best way to reheat is in the oven. Cover with foil and warm at 350°F until heated through (about 20-30 minutes for a full dish). For single servings, the microwave works in a pinch—heat in 60-second intervals, stirring in between.
