Ingredients

Potatoes:

• 3 pounds (1.4 kg) russet or Yukon Gold potatoes, thinly sliced
• 1 teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon paprika (for extra color and flavor)
• ½ teaspoon garlic powder (optional, for extra depth of flavor)

Creamy Sauce:

• 4 tablespoons (60g) unsalted butter
• 4 cloves garlic, minced
• ¼ cup (30g) all-purpose flour
• 2 cups (480ml) whole milk
• 1 cup (240ml) heavy cream
• 1 teaspoon Dijon mustard (for a subtle tang)
• ½ teaspoon nutmeg (optional, adds warmth)
• 1 ½ cups (150g) grated sharp cheddar cheese
• ½ cup (50g) grated Parmesan cheese

Topping:

• ½ cup (50g) grated Gruyère or mozzarella cheese
• 2 tablespoons chopped fresh parsley (for garnish)

Instructions

Step 1: Preheat Oven and Prepare Potatoes

1. Preheat your oven to 375°F (190°C).
2. Peel and thinly slice the potatoes to about ⅛-inch thickness. A mandoline slicer helps for uniform slices.
3. Place the potato slices in a large bowl and season with salt, black pepper, paprika, and garlic powder.

Step 2: Make the Creamy Sauce

1. In a medium saucepan over medium heat, melt the butter.
2. Add the minced garlic and sauté for 1 minute until fragrant.
3. Sprinkle in the flour and whisk constantly for 1-2 minutes to create a smooth roux.
4. Slowly pour in the milk and heavy cream, whisking continuously to prevent lumps.
5. Stir in the Dijon mustard, nutmeg, and bring the mixture to a gentle simmer, letting it thicken for about 5 minutes.
6. Remove from heat and stir in cheddar cheese and Parmesan cheese until melted and smooth.

Step 3: Assemble the Scalloped Potatoes

1. Grease a 9×13-inch baking dish with butter or non-stick spray.
2. Arrange half of the potato slices in an even layer in the dish.
3. Pour half of the cheese sauce evenly over the potatoes.
4. Repeat with the remaining potatoes and top with the remaining sauce.
5. Sprinkle Gruyère or mozzarella cheese over the top.

Step 4: Bake the Potatoes

1. Cover the baking dish with foil and bake for 45 minutes.
2. Remove the foil and bake for another 25-30 minutes until the top is golden brown and bubbling.
3. Let the potatoes rest for 10 minutes before serving.
4. Garnish with fresh parsley for a burst of color and flavor.

Tips for Perfect Scalloped Potatoes

• Use the right potatoes: Russet potatoes yield a softer texture, while Yukon Golds hold their shape better.
• Slice potatoes thinly and evenly: This ensures they cook evenly and absorb the creamy sauce perfectly.
• Don’t skip the foil: Covering the dish for the first part of baking prevents the top from burning while the potatoes cook.
• Rest before serving: Allowing the dish to rest helps the sauce thicken and set for perfect slices.
