Scalloped potatoes are a classic comfort food, featuring tender sliced potatoes baked in a creamy, cheesy sauce. This recipe is perfect for a 9-inch baking dish, delivering a rich, flavorful side that pairs well with roast meats or holiday feasts. Its layered presentation and luscious texture make it a crowd-pleaser every time.
Ingredients
- 3 pounds (about 4-5 large) Russet or Yukon Gold potatoes, thinly sliced
- 2 cups shredded sharp cheddar cheese
- 1 cup grated Parmesan cheese
- 2 cups whole milk
- 1 cup heavy cream
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 1 small onion, finely chopped (optional)
- 2 cloves garlic, minced
- 1 teaspoon salt
- ½ teaspoon black pepper
<½ teaspoon paprika (optional)
<¼ teaspoon ground nutmeg (optional)
Instructions
- Preheat your oven to 375°F (190°C). Grease a 9-inch baking dish with butter or non-stick spray to prevent sticking.
- Prepare the potatoes: Wash and peel the potatoes if desired. Using a sharp knife or mandoline, slice the potatoes into thin, even rounds about 1/8 inch thick. Rinse the slices in cold water to remove excess starch, then pat dry with a clean towel.
- Make the sauce: In a medium saucepan, melt the butter over medium heat. Add the chopped onion (if using) and cook until translucent, about 3 minutes. Stir in the minced garlic and cook for another 30 seconds. Whisk in the flour and cook for 1 minute to eliminate raw flour taste. Gradually pour in the milk and heavy cream, whisking constantly to prevent lumps. Add salt, pepper, paprika, and nutmeg. Bring the mixture to a gentle simmer, stirring frequently, until it thickens slightly, about 3-5 minutes.
- Layer the potatoes: Spread a thin layer of sauce at the bottom of the prepared dish. Arrange a layer of sliced potatoes over the sauce, slightly overlapping. Pour a portion of the remaining sauce over the potatoes, then sprinkle with a handful of shredded cheddar and Parmesan cheeses. Repeat the layering process—potatoes, sauce, cheeses—until all ingredients are used, ending with a cheese layer on top.
- Bake the dish: Cover with foil and bake for 45 minutes. Remove the foil and continue baking for an additional 15-20 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork. Let it rest for 10 minutes before serving to allow the dish to set and make slicing easier.
- Garnish with chopped parsley if desired, then serve hot.
Tips
- Use a mandoline for perfectly even potato slices, which ensures consistent cooking and a professional look.
- If you prefer a richer flavor, add a splash of white wine or a teaspoon of Dijon mustard to the sauce.
- To make this dish dairy-free, substitute the milk and cream with almond or coconut milk, and use a dairy-free cheese alternative.
- Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave, adding a splash of milk if the dish has dried out.
Serving Suggestions
Scalloped potatoes make an excellent side dish for roasted meats like ham, chicken, or beef. They also pair beautifully with steamed vegetables or a fresh green salad for a balanced meal. For special occasions, serve with a crusty baguette or a glass of white wine to elevate the dining experience.
Variations
For a twist on the classic scalloped potatoes, consider adding cooked bacon bits, sautéed mushrooms, or caramelized onions between the layers. You can also swap the cheddar and Parmesan for Gruyère or Swiss cheese for a different flavor profile. To make it more filling, add cooked diced ham or cooked ground sausage within the layers. For a lighter version, replace heavy cream with more milk and reduce the cheese quantity slightly.
Storage and Reheating
Leftover scalloped potatoes can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, cover the dish with foil and bake at 350°F (175°C) for about 20-25 minutes until heated through. Alternatively, reheat individual portions in the microwave on high for 2-3 minutes, stirring halfway through. If the dish has dried out, add a splash of milk or cream before reheating to restore creaminess.
Frequently Asked Questions
Can I prepare scalloped potatoes ahead of time?
Yes, you can assemble the dish up to 24 hours in advance. Cover it tightly with plastic wrap and refrigerate. When ready to bake, remove from the fridge and let it sit at room temperature for 15-20 minutes before baking. Increase baking time by about 10 minutes to account for the chilled dish.
How do I prevent the top from burning or becoming too crispy?
To keep the top golden but not burnt, cover the dish with foil during the initial baking phase. Remove the foil in the last 15 minutes to allow the cheese to brown evenly. If your oven has hot spots, rotate the dish midway through baking.
Can I use sweet potatoes instead of regular potatoes?
Absolutely! Sweet potatoes add a lovely sweetness and vibrant color. Keep in mind that they may cook faster, so check for tenderness around the 40-minute mark. Adjust seasoning to balance the sweetness if desired.
What is the best way to slice potatoes for scalloped potatoes?
Using a mandoline slicer ensures uniform slices, which cook evenly and look professional. If you don’t have one, use a sharp knife and cut as evenly as possible, taking care to maintain consistent thickness for even baking.
Is it necessary to peel the potatoes?
No, peeling is optional. Leaving the skin on adds extra texture and nutrients, but for a smoother dish, peel the potatoes before slicing. Rinsing the slices after peeling helps remove excess starch.
