Christmas Scalloped Potatoes

You know those dishes that show up at every single holiday dinner and somehow never get old? That's Christmas scalloped potatoes at our house.

Last December, I was putting together our Christmas dinner menu when Bradley asked if we were making "those cheesy layered potatoes again." Even my teenage son who pretends he's too cool for family dinners was already counting on them. That's when I knew this recipe had officially become a family tradition.

Here's the thing about scalloped potatoes – they look fancy enough for your holiday table, but they're actually pretty straightforward to make. Thin potato slices swimming in a creamy garlic sauce, layered with sharp cheddar cheese, all baked until golden and bubbly. If you're looking for more classic holiday sides, my best mashed potatoes are another crowd favorite that pairs beautifully with this dish.

I learned to make scalloped potatoes during my cooking school days, but I've tweaked this version over the years to make it more family-friendly. The combination of whole milk and vegetable broth keeps the sauce rich but not too heavy, and the fresh thyme adds just the right amount of flavor without being too fancy for the kids.

Ingredients for Christmas Scalloped Potatoes

For the Creamy Sauce:

• 3 tablespoons unsalted butter, plus extra for greasing the pan
• ¼ cup all-purpose flour
• 2 cups whole milk
• 1 cup vegetable broth
• 4 garlic cloves, grated
• 1 tablespoon fresh thyme leaves, chopped
• 2 teaspoons sea salt
• ½ teaspoon freshly ground black pepper

For the Potato Layers:

• 3 pounds Yukon Gold potatoes, sliced ⅛-inch thick
• ½ medium yellow onion, thinly sliced
• 1½ cups grated sharp cheddar cheese

The Yukon Gold potatoes are my go-to for this recipe. Their creamy texture and thin skin means you don't even have to peel them, which saves a ton of time. Trust me on this one – I tried using russet potatoes once and they turned out way too starchy.

How to Make the Best Scalloped Potatoes

Prepare Your Baking Dish:

1. Preheat your oven to 400°F.
2. Grab a 9x13-inch baking dish and butter it generously – this prevents sticking and adds extra flavor to those bottom layers.

Make the Creamy Garlic Sauce:

3. In a medium skillet over medium heat, melt the 3 tablespoons of butter until it's bubbling gently.
4. Add the flour and whisk constantly for about 1 minute. This cooks out the raw flour taste and creates your roux.
5. Slowly pour in the milk while whisking continuously. Then add the vegetable broth, still whisking. The key here is going slow – if you dump it all in at once, you'll end up with lumps.
6. Add the grated garlic, chopped thyme, salt, and pepper to the sauce.
7. Keep cooking and whisking often for 2 to 3 minutes. You'll know it's ready when it lightly coats the back of a spoon. Remove from heat.

Honestly? This sauce is so good that Amy once asked if she could just drink it. I had to explain that's not exactly how dinner works.

Layer Your Scalloped Potatoes:

8. Arrange half of the sliced potatoes in an even layer at the bottom of your prepared baking dish. Try to overlap them slightly like shingles on a roof.
9. Scatter half of the sliced onion over the potatoes.
10. Pour half of your creamy sauce over the onions, making sure it gets into all the crevices.
11. Sprinkle 1 cup of the grated cheddar cheese evenly over everything.
12. Repeat the whole process with the remaining potatoes, onion, sauce, and the final ½ cup of cheese on top.

Bake Until Golden and Tender:

13. Cover the baking dish tightly with aluminum foil and bake for 30 minutes. This first covered baking helps the potatoes get tender without the top burning.
14. Remove the foil and continue baking for another 35 to 40 minutes. The potatoes should be fork-tender, and that cheese on top should be gorgeously browned and bubbly.
15. Let the dish stand at room temperature for about 20 minutes before serving. This resting time lets everything set up so your slices hold together better.

The hardest part is waiting those 20 minutes. Last Christmas, John tried sneaking a spoonful straight from the oven and burned his mouth. Patience is key here.

Storage and Reheating Tips for Scalloped Potatoes

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

To reheat, cover with foil and warm in a 350°F oven for about 20 minutes, or until heated through. You can also reheat individual portions in the microwave, though the oven keeps the texture better.

Honestly, these taste even better the next day once all the flavors have had time to marry together. Bradley has been known to eat them cold straight from the fridge for breakfast, which I pretend not to notice.

You can also freeze unbaked scalloped potatoes for up to 2 months. Just assemble everything in a freezer-safe dish, cover tightly, and freeze. When you're ready to bake, thaw in the refrigerator overnight and add about 10 minutes to the covered baking time.

Tips for Making Perfect Christmas Scalloped Potatoes

Slice those potatoes evenly. A mandoline slicer is your best friend here. It gets every slice exactly ⅛-inch thick, which means they all cook at the same rate. I learned this lesson the hard way when my first batch had some potatoes that were mushy while others were still crunchy.

Don't skip the resting time. I know 20 minutes feels like forever when everyone's hungry, but it really does make a difference. The sauce thickens up and everything holds together so much better.

Use freshly grated cheese. Pre-shredded cheese has anti-caking agents that can make your sauce grainy. It takes an extra few minutes to grate your own, but the creamy texture is worth it.

Try different cheese combinations. While I love sharp cheddar, you can use Gruyère for something fancier, or mix cheddar with Parmesan for extra depth. Just keep the total amount at 1½ cups.

Add bacon for a twist. Sometimes I'll cook up 6 strips of bacon, crumble them, and add them between the layers. Not exactly traditional, but Bradley acts like I'm the best mom in the world when I do this.

Watch the salt level if you're using salted butter or a salty cheese. You might want to cut back to 1½ teaspoons of salt in the sauce.

Variations for Scalloped Potatoes

Herb it up with different fresh herbs. Rosemary works beautifully, or try a mix of parsley and chives for something brighter.

Make it lighter by using half-and-half instead of whole milk, though it won't be quite as rich.

Add vegetables like thinly sliced carrots or turnips mixed in with the potatoes for extra nutrition and color.

Go all-cheese with a combination of Gruyère, fontina, and Parmesan for fancy dinner party vibes.

Spice things up with a pinch of cayenne pepper or some diced jalapeños in the sauce.

Make individual portions in ramekins for a more elegant presentation. Just reduce the baking time to about 45 minutes total.
