Tools You'll Need

• 2-quart or 9x13-inch baking dish
• Sharp knife or mandoline
• Saucepan
• Whisk
• Aluminum foil

Ingredients

• 3 lbs russet or Yukon Gold potatoes, peeled and thinly sliced (⅛-inch thick)
• 3 tablespoons butter
• 3 tablespoons all-purpose flour
• 2 cups whole milk, warmed
• 1 cup heavy cream
• 2 cloves garlic, minced
• 1 teaspoon salt
• ½ teaspoon black pepper
• ¼ teaspoon ground nutmeg (optional)
• 1½ cups shredded sharp cheddar cheese, divided
• ¼ cup grated Parmesan cheese (optional)

Instructions

Prepare the Potatoes:

1. Preheat oven to 375°F (190°C). Grease a 2-quart or 9x13-inch baking dish.
2. Peel potatoes and slice them thinly (about ⅛ inch). A mandoline makes this quick and ensures even slices. Place sliced potatoes in a bowl of cold water to prevent browning while you prepare the sauce.

Make the Sauce:

1. In a medium saucepan, melt butter over medium heat. Add flour and whisk constantly for 1-2 minutes until the mixture is bubbly and light golden.
2. Gradually whisk in warm milk and heavy cream, stirring constantly to prevent lumps. Add garlic, salt, pepper, and nutmeg (if using). Continue to cook, whisking often, until the sauce thickens, about 5-7 minutes.
3. Remove from heat and stir in 1 cup of the shredded cheddar cheese until melted and smooth.

Assemble and Bake:

1. Drain potatoes and pat dry with paper towels. Arrange half of the potato slices in the prepared baking dish, overlapping slightly. Pour half of the cheese sauce over the potatoes. Sprinkle with a little of the remaining cheddar. Repeat with the remaining potatoes and sauce, ending with a final layer of sauce.
2. Top with the remaining ½ cup cheddar and the Parmesan cheese (if using).
3. Cover the dish with foil and bake for 45 minutes. Remove foil and bake for another 20-30 minutes until the potatoes are tender when pierced with a knife and the top is golden and bubbly.
4. Let rest for 10-15 minutes before serving. The sauce will thicken as it cools.

Pro Tips

• Slice potatoes evenly: Uniform slices ensure even cooking. A mandoline is the best tool for this.
• Use starchy potatoes: Russets break down slightly and create a creamier texture; Yukon Golds hold their shape a bit more and have a buttery flavor. A mix works well.
• Don't skip the resting time: Letting the dish rest after baking allows the sauce to set, making it easier to serve.
• Make ahead: Assemble the casserole (without the final baking) up to 24 hours in advance. Cover and refrigerate. When ready to bake, add 10-15 minutes to the covered baking time.
• Add a crispy topping: For extra crunch, sprinkle buttered breadcrumbs or crushed crackers over the cheese during the last 10 minutes of baking.

Recipe Variations

• Gruyère Scalloped Potatoes: Replace cheddar with Gruyère for a nutty, sophisticated flavor.
• Bacon: Sprinkle cooked, crumbled bacon between layers.
• Ham: Add diced ham between the layers for a heartier dish.
• Onion: Sauté 1 finely chopped onion with the butter before adding the flour.
• Herbed: Add 1 tablespoon fresh thyme or rosemary to the sauce.
• Dairy-Free: Use unsweetened almond milk or oat milk, vegan butter, and a dairy‑free cheese.
• Gluten-Free: Substitute all-purpose flour with a gluten‑free 1:1 blend or cornstarch (use 2 tbsp cornstarch mixed with 2 tbsp water as a slurry).

FAQs

What's the difference between scalloped potatoes and au gratin?
Scalloped potatoes are typically made with a cream sauce and no cheese, while au gratin includes cheese and often breadcrumbs. This recipe is a hybrid – creamy sauce with cheese – the best of both worlds!

Can I use heavy cream only?
Yes, you can use all heavy cream for a richer dish. Reduce the total liquid to 2½ cups of cream and omit the milk.

Why are my potatoes still hard after baking?
They may have been sliced too thick, or the oven temperature may have been too low. Ensure even, thin slices and test for doneness with a knife before removing from the oven.

How do I store leftovers?
Store in an airtight container in the refrigerator for up to 4 days. Reheat in the oven at 350°F for 15-20 minutes or in the microwave.

Can I freeze scalloped potatoes?
Yes, but the texture may change slightly. Assemble but don't bake; wrap tightly and freeze for up to 3 months. Thaw overnight and bake as directed.

What's the best cheese for scalloped potatoes?
Sharp cheddar is classic, but Gruyère, fontina, or a blend all work beautifully. A little Parmesan adds a nice salty kick.

Can I make this in a slow cooker?
Yes, layer potatoes and sauce in a slow cooker and cook on low for 4-5 hours, then top with cheese and let melt. The texture will be softer than baked.

These Scalloped Potatoes are the ultimate comfort food – creamy, cheesy, and irresistibly tender. Whether you're serving them for a holiday feast or a cozy weeknight dinner, they're guaranteed to be a hit. The rich sauce, the perfectly cooked potatoes, and the golden, bubbly topping make every bite pure bliss.

Make them ahead for stress‑free entertaining, or bake them fresh and enjoy the aroma filling your kitchen. However you serve them, they'll quickly become a family favorite. Pair them with ham, roast beef, or a holiday turkey for a meal that everyone will remember.
