Irresistible Thanksgiving Scalloped Potatoes

If you ask me, scalloped potatoes are one of those dishes that belong on every Thanksgiving table.

This classic side dish features thin-sliced potatoes baked in a creamy sauce with four types of cheese. The cream gets flavored with nutmeg, thyme, and garlic powder for a sauce that coats every layer.

Shallots add a subtle sweetness while mozzarella, asiago, gruyere, and parmesan create a rich, melty topping. It bakes until the potatoes are tender and the top turns golden brown.

It’s a comforting dish that feeds a crowd, perfect for holiday gatherings when you need something hearty and satisfying.

What Kind of Potatoes Should I Use?

For scalloped potatoes, you’ll want to reach for starchy or all-purpose potatoes rather than waxy varieties. Russet potatoes are a classic choice because they absorb the cream beautifully and create that tender, melt-in-your-mouth texture we’re after. Yukon Golds are another great option – they have a naturally buttery flavor and hold their shape a bit better while still soaking up all that cheesy goodness. Avoid red potatoes or new potatoes for this recipe, as they’re too waxy and won’t give you that creamy, layered texture that makes scalloped potatoes so special.

Options for Substitutions

This recipe is pretty forgiving when it comes to swaps, so feel free to work with what you have:

• Cheese blend: The mix of mozzarella, asiago, gruyere, and parmesan creates a great flavor, but you can substitute with what’s in your fridge. Try using all gruyere for a classic approach, or swap in fontina, gouda, or white cheddar. Just keep the total amount of cheese the same.
• Gruyere: If gruyere is too pricey or hard to find, Swiss cheese makes a solid substitute with a similar nutty flavor.
• Shallot: No shallots? Use about 1/4 cup of finely chopped yellow onion or 2 minced garlic cloves instead.
• Heavy cream: You can use half-and-half for a lighter version, though the sauce won’t be quite as rich. For an even lighter option, try whole milk mixed with 2 tablespoons of flour to help it thicken.
• Fresh thyme: Dried thyme works fine here – just use about 1/2 teaspoon since dried herbs are more concentrated.
• Potatoes: Russets are traditional and give you a fluffy texture, but Yukon golds create a creamier dish. Either works great, so use whichever you prefer.

Watch Out for These Mistakes While Cooking

The biggest mistake when making scalloped potatoes is slicing them unevenly, which leads to some pieces turning mushy while others stay crunchy – aim for slices about 1/8 inch thick using a mandoline or sharp knife for consistent results.

Another common error is skipping the stovetop simmer before baking, as those 5 minutes help the cream thicken slightly and start cooking the potatoes, preventing a watery final dish.

To avoid burnt edges and undercooked centers, make sure your cream fully covers the potatoes during that stovetop step, and if the top starts browning too quickly in the oven, tent it loosely with foil for the last 10 minutes of baking.

Don’t rush the 5-minute rest after baking – this allows the sauce to set up properly so your scalloped potatoes hold their shape when you scoop them out instead of turning into a soupy mess on the plate.

What to Serve With Scalloped Potatoes?

Scalloped potatoes are the perfect side dish for any holiday meal, especially alongside roasted turkey, ham, or prime rib. The creamy, cheesy potatoes pair really well with green beans, roasted Brussels sprouts, or a simple arugula salad to balance out all that richness. If you’re serving these for Thanksgiving, they go great with cranberry sauce and stuffing, and honestly, they’re so good that they can almost steal the show from the main course. For a lighter meal, try serving them with roasted chicken or pork chops and some steamed broccoli on the side.

Storage Instructions

Store: Leftover scalloped potatoes keep really well in the fridge for up to 4 days. Just cover the baking dish tightly with foil or transfer them to an airtight container once they’ve cooled down. They actually taste pretty amazing the next day after all those flavors have had time to hang out together.

Make Ahead: You can assemble this dish completely the day before and keep it covered in the fridge until you’re ready to bake. Just add about 10-15 extra minutes to the baking time since it’ll be going in cold. This is a total lifesaver when you’re juggling a bunch of Thanksgiving dishes!

Reheat: Cover the dish with foil and warm it in a 350°F oven for about 20-25 minutes until heated through. You can also microwave individual portions for 2-3 minutes, though the oven method keeps them creamier and prevents the edges from drying out.

Ingredients

For the potatoes and seasoning:

• 2.25 lb potatoes (peeled and sliced into 1/8-inch thick rounds)
• 3 tbsp butter (I like Kerrygold unsalted butter for this)
• 1 large shallot
• 1.5 tsp thyme
• 1.25 tsp salt
• 0.75 tsp pepper
• 2.5 cups cream (I use Horizon Organic heavy cream for a richer sauce)
• 0.5 tsp nutmeg (freshly grated provides the best aroma)
• 0.5 tsp garlic powder

For the cheese blend:

• 0.5 cup mozzarella
• 0.5 cup asiago
• 0.5 cup gruyere (melted slowly to ensure a smooth texture)
• 0.33 cup parmesan

Step 1: Prepare Mise en Place and Preheat

• 2.25 lb potatoes, peeled and sliced into 1/8-inch thick rounds
• 1 large shallot, minced
• 1.5 tsp thyme
• 1.25 tsp salt
• 0.75 tsp pepper
• 0.5 cup mozzarella
• 0.5 cup asiago
• 0.5 cup gruyere
• 0.33 cup parmesan
• 0.5 tsp nutmeg
• 2.5 cups cream

Preheat your oven to 425°F.

While it heats, peel and slice the potatoes into 1/8-inch thick rounds—I find using a mandoline here saves time and ensures even cooking.

Mince the shallot finely.

In one small bowl, combine the thyme, salt, and pepper.

In another bowl, combine the mozzarella, asiago, and gruyere cheeses.

Have the parmesan, nutmeg, and cream measured and ready nearby.

Step 2: Layer Potatoes, Aromatics, and Cheese in Skillet

• 1.5 tbsp butter
• 1.5 lb potatoes from Step 1
• shallot-thyme mixture from Step 1
• cheese blend from Step 1
• 0.75 lb potatoes from Step 1
• remaining shallot-thyme mixture from Step 1

Melt 1.5 tablespoons of butter in a 10-12 inch oven-safe skillet over medium heat.

Create the first layer with half of the sliced potatoes, slightly overlapping them for even cooking.

Sprinkle two-thirds of the shallot-thyme mixture over the potatoes, then distribute half of the cheese blend from Step 1 evenly across.

Layer the remaining potatoes on top, followed by the last of the shallot-thyme mixture.

Step 3: Simmer the Potato Base on Stovetop

• 2.5 cups cream
• 0.5 tsp nutmeg
• 0.5 tsp garlic powder

Pour the cream evenly over the layered potatoes and sprinkle the freshly grated nutmeg and garlic powder across the surface.

Bring to a gentle simmer over medium heat and cook for about 5 minutes—this helps the potatoes begin to soften and allows the cream to infuse with the seasonings.

I like to use freshly grated nutmeg here because it releases its aromatic oils and tastes far superior to pre-ground.

Step 4: Top with Butter and Cheese, Then Bake

• 1.5 tbsp butter
• remaining cheese blend from Step 1
• 0.33 cup parmesan

Remove the skillet from heat and dot the top with the remaining 1.5 tablespoons of butter, cut into small pieces.

Scatter the remaining cheese blend from Step 1 over the surface, then finish with the parmesan.

Transfer the skillet to the preheated 425°F oven and bake for 25-30 minutes, until the top is golden brown and the cream is bubbling around the edges.

Step 5: Rest and Serve

Remove the skillet from the oven and let the scalloped potatoes rest for 5 minutes before serving.

This resting period allows the cream sauce to set slightly, making it easier to serve and ensuring each spoonful stays creamy.

I find this brief rest makes a noticeable difference in texture and presentation at the table.
