Step-by-Step Instructions

1. Prepare Your Potatoes

Wash 3 lbs of russet potatoes under cold running water, rubbing them gently with your hands to remove any dirt
Peel the potatoes using a vegetable peeler, working downward from the top to remove just the thin skin
Fill a large bowl with cold water and add a squeeze of fresh lemon juice (this prevents oxidation and browning)
Using a mandoline slicer set to 1/8-inch thickness, carefully slice each peeled potato into thin, even rounds
Immediately place each slice into the cold water to prevent discoloration and help keep them from sticking together
Once all potatoes are sliced, gently drain them in a colander, then pat them dry with paper towels to remove excess moisture

2. Make the Cream Sauce

Melt 4 tablespoons of unsalted butter in a medium saucepan over medium heat, allowing it to foam gently but not brown
Add 4 minced garlic cloves to the melted butter and stir constantly for about 30 seconds until fragrant (be careful not to let the garlic burn)
Sprinkle 4 tablespoons of all-purpose flour over the garlic and butter, stirring continuously with a whisk for about 2 minutes to create a smooth roux
Slowly pour in 2.5 cups of warmed whole milk while whisking constantly to prevent lumps from forming
Continue whisking until the mixture is smooth and starting to thicken, which should take about 3-4 minutes
Add 1 cup of warmed heavy cream, whisking until fully combined and smooth
Remove from heat and season with 1 teaspoon salt, 1/2 teaspoon black pepper, 1/4 teaspoon nutmeg, and 1 teaspoon fresh thyme leaves
Stir in 1.5 cups of the shredded sharp cheddar cheese until completely melted and incorporated into the sauce

3. Prepare the Baking Dish

Position your oven rack to the middle position and preheat your oven to 350°F (175°C)
Lightly butter a 9×13-inch baking dish, making sure to coat the bottom and sides evenly
Arrange a single layer of the dried potato slices on the bottom of the prepared baking dish, slightly overlapping them like roof tiles
Season this first layer lightly with a pinch of salt and pepper

4. Layer the Potatoes and Sauce

Pour about 1 cup of the cream sauce evenly over the first layer of potatoes, tilting the dish to distribute the sauce throughout
Create another layer of potato slices, again slightly overlapping them for even cooking
Pour another 1 cup of sauce over this layer, using your spoon to ensure it reaches into the nooks and crannies between potatoes
Continue alternating layers of potatoes and sauce, ending with a layer of sauce so all potatoes are covered
You should have enough sauce to completely coat all layers with a thin layer remaining on top

5. Prepare the Topping

In a small bowl, combine 1/2 cup panko breadcrumbs, the remaining 1/2 cup shredded cheddar cheese, and 2 tablespoons grated parmesan cheese
Drizzle 2 tablespoons of melted butter over the breadcrumb mixture and stir gently with a fork until the mixture resembles coarse sand
Sprinkle this topping evenly over the entire surface of the scalloped potatoes, covering any exposed sauce

6. Bake Until Golden

Place the baking dish in the preheated 350°F oven on the middle rack
Bake uncovered for 45-55 minutes, until the top is golden brown and you can see the sauce bubbling around the edges of the dish
To test for doneness, insert a thin knife or skewer into the center—potatoes should slide through easily with no resistance
If the top is browning too quickly before the potatoes are tender, loosely tent with aluminum foil and continue baking
Remove from the oven and let cool for 5-10 minutes before serving, which allows the sauce to set slightly and makes serving easier

Tips for Success

Following these tips will help you create the most delicious scalloped potatoes possible. They come from years of making this dish.

Pro tips for perfect results:

Slice your potatoes uniformly thin so they cook at the same rate; use a mandoline slicer for consistent results
Keep your sliced potatoes in cold water until you’re ready to use them to prevent browning and oxidation
Warm your milk and cream before adding to the roux to prevent lumps and achieve a silky smooth sauce
Make the sauce slightly thinner than you’d normally want it, as it will thicken as the potatoes bake and release their starch
Don’t skip the nutmeg—just a pinch adds sophisticated depth that elevates the entire dish
Layer your potatoes carefully so they cook evenly and look beautiful when plated
Allow the dish to rest for 5-10 minutes after baking before serving to let the sauce set and make cutting cleaner
Use real cheddar cheese rather than pre-shredded varieties, which contain anti-caking agents and won’t melt as smoothly
Taste your sauce and adjust seasoning before layering if possible so you don’t need to over-salt
If making ahead, assemble the dish completely, cover with plastic wrap, and refrigerate for up to 24 hours before baking

Storage and Reheating

Scalloped potatoes store beautifully and actually taste just as good, if not better, the next day. The flavors continue to meld together as it sits.

Storage and reheating guidelines:

Store leftover scalloped potatoes in an airtight container in the refrigerator for up to 4 days
The creamy sauce and potatoes naturally keep well due to the dairy and starch content
To reheat in the oven, cover loosely with aluminum foil and warm at 350°F for about 15-20 minutes until heated through
For quicker reheating, cover individual portions and microwave on medium power for 2-3 minutes, stirring halfway through
You can also reheat on the stovetop in a skillet over medium-low heat, stirring gently to prevent scorching
Reheated scalloped potatoes are perfect for lunch the next day, either served hot or even cold straight from the refrigerator
Freeze completely cooled scalloped potatoes in an airtight freezer container for up to 2 months for longer storage

Frequently Asked Questions

1. Can I Make Scalloped Potatoes Ahead of Time?

Absolutely, and this is one of the best features of the dish. Assemble the entire scalloped potatoes recipe in your baking dish, cover it tightly with plastic wrap, and refrigerate for up to 24 hours.

Bake as directed, though you may need to add 5-10 minutes to the cooking time since the dish will be cold when it goes into the oven.

2. Why Is My Scalloped Potatoes Recipe Watery?

This usually happens when potatoes release too much starch during baking or when the sauce is too thin to begin with. Pat your sliced potatoes very dry before layering, and make sure your cream sauce is slightly thicker than you want the final dish to be.

The potatoes will release some starch during baking, which actually helps thicken the sauce naturally.

3. Can I Use a Different Type of Potato?

Yes, though you may need to adjust cooking time slightly. Yukon gold potatoes work beautifully and create a creamier dish naturally.

Avoid waxy potatoes like red potatoes, as they don’t absorb the sauce as well, but starchy varieties like russets or Idaho potatoes are ideal.

4. How Do I Keep the Cheese Topping From Getting Too Dark?

If your cheese topping is browning too quickly while the potatoes underneath are still firm, simply tent the dish loosely with aluminum foil. Remove the foil during the last 10-15 minutes of baking to allow the top to re-crisp.

Lower your oven temperature slightly if browning occurs consistently in your oven.

5. Is There a Dairy-Free Version of Scalloped Potatoes?

You can certainly make a dairy-free version by substituting full-fat coconut milk for the cream and using a plant-based milk of your choice in place of dairy milk. Use dairy-free butter and nutritional yeast for that cheese flavor if needed.

The texture will be slightly different but still delicious and satisfying.
