How to Make scalloped potatoes recipe

Creating these creamy potatoes is a rewarding process that involves slicing, simmering, and slow-baking. By following these clear steps, you will ensure that your potatoes are perfectly cooked and your sauce is thick and smooth.

Ingredients

3 lbs Yukon Gold or Russet potatoes, peeled and sliced 1/8 inch thick
1/4 cup unsalted butter
1 small yellow onion, finely diced
3 cloves garlic, minced
1/4 cup all-purpose flour
2 cups whole milk
1 cup heavy cream
1 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
Cooking spray or extra butter for the baking dish

Directions

Step 1: Oven and Dish Preparation

Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with cooking spray or a bit of butter to prevent the potatoes from sticking to the sides.

Step 2: Prepare the Potatoes

Peel the potatoes and slice them into thin, uniform rounds about 1/8-inch thick. Using a mandoline slicer is highly recommended to ensure they cook evenly. Place the sliced potatoes in a bowl of cold water to prevent browning while you make the sauce, then drain and pat them dry before use.

Step 3: Sauté Aromatics and Make Roux

In a large saucepan, melt the butter over medium heat. Add the diced onions and cook for 3 to 4 minutes until they become translucent. Stir in the minced garlic and cook for another minute. Sprinkle the flour over the butter and onion mixture, whisking constantly for 1 to 2 minutes to cook out the raw flour taste.

Step 4: Whisk the Cream Sauce

Slowly pour in the milk and heavy cream while whisking continuously to avoid lumps. Continue cooking and whisking over medium heat until the sauce thickens and begins to bubble. Stir in the salt, pepper, and thyme. Remove from heat.

Step 5: Layer the Dish

Arrange half of the potato slices in an even layer in the bottom of the prepared baking dish. Pour half of the cream sauce over the potatoes. Repeat with the remaining potatoes and the rest of the sauce, spreading it evenly to cover all the potatoes.

Step 6: Bake and Brown

Cover the baking dish tightly with aluminum foil. Bake in the preheated oven for 45 minutes. Remove the foil and continue baking for another 15 to 20 minutes, or until the potatoes are tender when pierced with a fork and the top is bubbly and golden brown.

Step 7: Rest and Serve

Remove the dish from the oven and let it rest for 10 minutes before serving. This allows the sauce to set and thicken further, making it easier to scoop and serve.

How to Serve scalloped potatoes recipe

Scalloped potatoes are best served warm, straight from the baking dish. They make a wonderful companion to a honey-glazed ham, a juicy roast beef, or even a simple rotisserie chicken. To add a pop of color and freshness, garnish the top with a sprinkle of fresh chopped parsley or extra thyme leaves. If you are serving this for a holiday, it looks beautiful placed in the center of the table as a shared side dish.

How to Store scalloped potatoes recipe

If you have leftovers, they store remarkably well. Place the cooled potatoes in an airtight container and keep them in the refrigerator for up to 4 days. To reheat, place a portion in the microwave or put the whole dish back in the oven at 350°F, covered with foil, until heated through. You may need to add a splash of milk if the sauce has thickened too much during storage. Freezing is not recommended as the texture of the cream sauce and potatoes can change significantly upon thawing.

Expert Tips for Perfect scalloped potatoes recipe

For the best results, use Yukon Gold potatoes; they have a naturally buttery flavor and hold their shape well while still becoming tender. If you use Russet potatoes, they will release more starch, which makes the sauce extra thick. Always try to slice the potatoes to the same thickness so they all finish cooking at the same time. If the top of your dish is browning too quickly, simply tent it loosely with foil for the remainder of the bake time. Lastly, don’t skip the resting period at the end! It is essential for the perfect sauce consistency.

Delicious Variations

While the classic version is hard to beat, you can easily customize this recipe. For “Au Gratin” style potatoes, add 1.5 cups of shredded cheddar or Gruyère cheese between the layers and on top. You can also add diced ham or cooked bacon pieces between the layers to turn this side dish into a hearty main course. For a different flavor profile, try adding a pinch of nutmeg to the cream sauce or using rosemary instead of thyme.

Frequently Asked Questions

Q: What is the difference between scalloped potatoes and potatoes au gratin?

Scalloped potatoes are typically cooked in a simple cream sauce (a roux-based sauce) without cheese. Potatoes au gratin usually include grated cheese between the layers and often have a breadcrumb topping.

Q: Why did my sauce curdle?

Sauce curdling usually happens if the heat is too high or if you use low-fat milk. Using whole milk and heavy cream, and baking at a moderate temperature, helps keep the sauce smooth and stable.

Q: Do I have to peel the potatoes?

While traditional recipes call for peeled potatoes for a silky texture, you can leave the skins on if you prefer a more rustic look. Just make sure to scrub them very well before slicing.

Q: Can I make this recipe ahead of time?

Yes! You can bake the dish fully, let it cool, and refrigerate it. Reheat it in the oven at 350°F until bubbly. Alternatively, you can prepare the sauce and slice the potatoes a few hours in advance, but keep the potatoes in water so they don’t turn brown.

Q: How do I know when the potatoes are done?

The best way to check is by inserting a sharp knife or a fork into the center of the dish. It should slide through the potato layers with absolutely no resistance.

Conclusion

Mastering the scalloped potatoes recipe is a gift to your kitchen and your guests. This dish brings a sense of warmth and tradition to any meal.
