Viral Christmas Recipe: Scalloped Potatoes – A Comforting Classic
Looking for a rich, creamy, and cheesy side dish that’s bound to impress? This Scalloped Potatoes recipe is perfect for holidays, family gatherings, or any time you crave a comforting classic. With layers of tender potatoes, savory sauce, and melted cheddar, it’s the ultimate crowd-pleaser.

What You’ll Need
Here’s everything required to create this decadent dish:
Ingredients
- Potatoes: Yukon Gold potatoes are ideal for their creamy texture and buttery flavor.
- Butter & Flour: These form the roux to thicken the luscious sauce.
- Vegetable Broth & Whole Milk: The perfect combo for a light yet creamy sauce. Using just milk can make it overly rich, so the broth balances it out beautifully.
- Garlic & Onion: Adds depth and savory flavor to the dish.
- Fresh Thyme: A touch of herbal freshness; dried thyme works in a pinch.
- Cheddar Cheese: For that tangy, nutty goodness that completes the dish.
- Salt & Pepper: Enhances all the flavors.
How to Make Scalloped Potatoes
1. Prep the Potatoes
Slice the potatoes into 1/8-inch-thick rounds. A mandoline slicer works great, but a sharp knife does the trick too. Aim for even slices so they cook evenly.
2. Make the Sauce
- Melt butter in a skillet and whisk in the flour to make a roux.
- Gradually add the milk and broth, whisking constantly to avoid lumps.
- Stir in garlic, thyme, salt, and pepper. Cook for 2-3 minutes or until the sauce lightly coats the back of a spoon. Avoid boiling to prevent the sauce from splitting.
3. Assemble the Casserole
- In a greased 9×13-inch baking dish, layer half the sliced potatoes and onions. Pour half the sauce over them and sprinkle with 1 cup of cheddar cheese.
- Repeat the process with the remaining potatoes, onions, sauce, and cheese.
4. Bake
- Cover the dish with foil and bake at 400°F for 30 minutes.
- Uncover and bake for another 35-40 minutes, or until the potatoes are tender and the top is golden brown.
- Let the dish rest for 20 minutes at room temperature before serving.
Pro Tips
- Even Slices: Thin, consistent potato slices ensure even cooking. Use a mandoline slicer for precision.
- Cheese Choice: Go for sharp cheddar for maximum flavor, but Gruyère or a cheese blend works wonderfully too.
- Herbs: Add a sprinkle of fresh parsley or chives before serving for a pop of color and flavor.
- Leftovers Are Gold: This dish tastes even better the next day as the flavors meld together!
