Ingredients You’ll Need

Simple yet essential, these ingredients are each carefully chosen to create the creamy, dreamy layers that make Cheesy Scalloped Potatoes such a showstopper. From the star potatoes to the secret seasoning touches, every element transforms this classic into something extraordinary.

• Russet or Yukon Gold Potatoes: Choose potatoes that hold their shape well and absorb all that rich sauce—Yukon Golds give a buttery flavor, while Russets turn ultra tender.
• Sharp Cheddar Cheese: The sharper the better, for extra tang and ooey-gooey meltiness in every layer.
• Gruyère Cheese: For a nutty depth and beautiful browning on top, Gruyère brings the wow factor.
• Heavy Cream: The secret to that luscious, velvety sauce that clings to each potato slice.
• Whole Milk: Balances out the richness of the cream, keeping the sauce from getting too heavy.
• Unsalted Butter: Adds a silky base and helps sauté the aromatics for deeper flavor.
• Yellow Onion: Sautéed until sweet and soft for a foundation of savory goodness.
• Garlic: Just a couple cloves make a big difference, delivering a subtle warmth throughout.
• All-Purpose Flour: Thickens the sauce without making it too dense.
• Fresh Thyme: Bright, herbal notes cut through the richness and elevate the whole dish.
• Salt and Black Pepper: Essential seasoning to bring out all the flavors and tie them together.
• Nutmeg: Just a pinch adds cozy, subtle depth to the cheesy sauce.

How to Make Cheesy Scalloped Potatoes

Step 1: Prep and Slice Your Potatoes

Start by peeling your potatoes to achieve that classic, tender texture. Using either a sharp knife or a mandoline slicer, cut the potatoes into thin, even slices—about 1/8-inch thick is perfect. Consistency here is key so the layers cook uniformly and absorb the creamy sauce beautifully. Once sliced, you can place the potatoes in a bowl of cold water to prevent browning while you prep the other ingredients.

Step 2: Make the Cheesy Cream Sauce

In a large saucepan, melt the butter over medium heat. Add the chopped onion and cook until it turns soft and translucent, about 5–6 minutes; stir in the minced garlic and sauté for another minute to deepen the flavor. Sprinkle the flour over the onions and cook, whisking constantly, to form a smooth roux. Gradually pour in the heavy cream and milk, whisking the whole time to prevent lumps. Once smooth, add half of your cheese blend, reserving some for the luscious top layer. Stir in the nutmeg, thyme, salt, and pepper, and let the sauce simmer until thickened and creamy.

Step 3: Layer the Potatoes and Sauce

Preheat your oven to 375°F (190°C) and grease a large baking dish so nothing sticks. Arrange half of your sliced potatoes in even, overlapping layers on the bottom of the dish. Pour half of your cheesy sauce over the potatoes, spreading it gently with a spatula. Repeat with the remaining potatoes and sauce, making sure every bit is coated and ready to soak up those flavors.

Step 4: Top with Cheese and Bake

Sprinkle the remaining cheddar and Gruyère generously over the sauced potatoes so every bite gets that stretchy, golden piece of goodness. Cover the dish with foil and bake for 35 minutes; then uncover and continue baking another 25–30 minutes, until the cheese on top bubbles and browns and a fork effortlessly pierces the potatoes. Let the Cheesy Scalloped Potatoes cool for 15 minutes—they’ll slice neatly and taste even better.

Step 5: Serve and Savor

Use a sharp knife or spatula to cut generous wedges or squares and serve hot. The irresistible aroma and the sight of that crusty, cheesy lid give everyone a reason to gather around the table. Your Cheesy Scalloped Potatoes may just vanish before the main course even arrives!

How to Serve Cheesy Scalloped Potatoes

Garnishes

For an extra burst of color and freshness, sprinkle some freshly chopped chives, parsley, or a few thyme sprigs right before serving. The herbs aren’t just pretty—they add brightness that cuts through the cheesy richness. A gentle twist of black pepper or a dusting of smoked paprika on top can also make your Cheesy Scalloped Potatoes look and taste extraordinary.

Side Dishes

These potatoes pair perfectly with everything from a classic glazed ham to roasted poultry or a simple green salad. The richness of Cheesy Scalloped Potatoes complements lighter sides like steamed asparagus, crisp green beans, or citrusy arugula. If you really want to go bold, serve them alongside grilled steaks or BBQ for an indulgent feast.

Creative Ways to Present

You can bake Cheesy Scalloped Potatoes in individual ramekins for an elegant plated dinner, or use a cast iron skillet for rustic charm on family nights. For a fun twist, layer in sautéed leeks, cooked bacon bits, or roasted garlic in between the potatoes. And if you’re hosting a brunch, serve smaller squares on a platter topped with a dollop of crème fraîche for a crowd-pleasing appetizer.

Make Ahead and Storage

Storing Leftovers

After enjoying your meal, let any leftover Cheesy Scalloped Potatoes cool completely. Transfer them to an airtight container or tightly wrap the baking dish with foil. They’ll keep beautifully in the refrigerator for up to 4 days, making lunch or weeknight dinners that much more delicious.

Freezing

If you want to prep ahead or save extra portions, Cheesy Scalloped Potatoes freeze surprisingly well. Let the dish cool fully, then cut into portions and wrap tightly in foil and plastic wrap, or use a freezer-safe container. They can stay frozen for up to 2 months. When you’re ready, thaw overnight in the fridge before reheating to keep the texture cozy and creamy.

Reheating

To recapture that fresh-from-the-oven flavor, reheat portions of Cheesy Scalloped Potatoes covered with foil in a 350°F oven until hot, about 20 minutes. For crispier edges, remove the foil for the last few minutes. You can also microwave single servings, but for the ultimate melted cheese experience, the oven is your best friend.

FAQs

Can I use a different type of cheese?

Absolutely, feel free to experiment! While sharp cheddar and Gruyère are classic for that signature Cheesy Scalloped Potatoes flavor, you can swap in Swiss, Monterey Jack, or even pepper jack for a kick. Just choose cheeses that melt well and bring flavors you love.

Can I make Cheesy Scalloped Potatoes gluten-free?

Yes! Substitute the all-purpose flour with your favorite gluten-free flour blend or cornstarch. Just use equal amounts and make sure to whisk well for a smooth, lump-free sauce.

What’s the best way to slice the potatoes evenly?

A mandoline slicer is truly your best friend for this job, providing perfectly uniform, thin slices every time. If you don’t have one, a sharp chef’s knife and a careful hand will also work. Just aim for consistent thickness so the potatoes cook at the same rate.

Can I add vegetables or proteins?

Definitely! Feel free to layer in spinach, sautéed mushrooms, caramelized onions, or slices of ham for a one-dish wonder. Cheesy Scalloped Potatoes are wonderfully adaptable to your taste and can become a stand-alone meal with a few creative add-ins.

Why are my scalloped potatoes watery?

This sometimes happens if the potatoes weren’t sliced thinly enough or if the sauce was too thin to start. Using starchy potatoes like Russets, thickening your sauce well, and ensuring a slow, steady bake helps achieve that signature thick, creamy texture.
