Why You’ll Love These Homemade Scalloped Potatoes
There is a reason scalloped potatoes have remained a favorite comfort-food recipe for generations.
- Simple ingredients: You only need potatoes, dairy, butter, flour, seasonings, and a few pantry staples.
- Creamy and comforting: The sauce coats every layer of potato.
- Perfect for gatherings: A large baking dish makes this recipe easy to share.
- Make-ahead friendly: You can prepare portions of the dish ahead of time.
- Versatile: Serve it with chicken, beef, pork, vegetables, or a simple salad.
- Beginner-friendly: There is no complicated cooking technique involved.
The key is slicing the potatoes thinly and evenly so that they cook at roughly the same rate.
Ingredients
For about 6 servings, you will need:
- 2 pounds potatoes, preferably Yukon Gold or Russet
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- 2 cups milk
- ½ cup heavy cream
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon dried thyme
- ½ cup finely grated Parmesan cheese, optional
- 1 tablespoon chopped fresh parsley, optional
Although scalloped potatoes traditionally do not require cheese, Parmesan can add extra savory flavor. If you prefer a strictly traditional version, simply leave it out.
Which Potatoes Are Best?
Choosing the right potato can make a noticeable difference.
Yukon Gold potatoes are an excellent option because they have a naturally buttery texture and hold their shape while becoming tender.
Russet potatoes are also a good choice. They contain more starch, which can help create a thicker, creamier sauce.
You can even combine the two varieties if you have both available.
Try to choose potatoes that are similar in size so that they are easier to slice evenly.
How to Make Easy Scalloped Potatoes
1. Prepare the Potatoes
Start by washing and peeling the potatoes. Peeling is optional, especially if you are using thin-skinned potatoes, but peeled potatoes give the dish a smoother, more traditional appearance.
Slice the potatoes into thin rounds, ideally around ⅛ inch thick.
A mandoline slicer can make this step faster, but a sharp kitchen knife works perfectly well. The most important thing is consistency. If some slices are very thick while others are extremely thin, they may finish cooking at different times.
Place the sliced potatoes in a bowl while you prepare the sauce.
2. Make the Creamy Sauce
Preheat your oven to 375°F (190°C).
Melt the butter in a saucepan over medium heat.
Add the flour and whisk continuously for about a minute. This creates a simple roux that helps thicken the sauce.
Slowly pour in the milk while whisking. Add the heavy cream and continue stirring until the mixture becomes smooth.
Season with salt, black pepper, garlic powder, onion powder, and dried thyme.
Cook the sauce gently until it thickens slightly. You do not need it to become extremely thick because it will continue cooking and thickening in the oven.
If you are using Parmesan, stir it into the warm sauce until incorporated.
3. Layer the Potatoes
Lightly grease a baking dish with butter or cooking spray.
Arrange a layer of sliced potatoes across the bottom of the dish.
Pour some of the creamy sauce over the potatoes.
Repeat the layers until all of the potatoes and sauce have been used.
Try to distribute the sauce evenly so that every layer gets some of that creamy flavor.
4. Bake Until Tender
Cover the baking dish tightly with aluminum foil and place it in the preheated oven.
Bake for approximately 45 minutes.
Remove the foil and continue baking for another 20 to 30 minutes, or until the potatoes are completely tender and the top is lightly golden.
A knife should slide easily through the center when the potatoes are finished.
If the top starts browning too quickly while the center is still firm, loosely cover the dish again with foil and continue baking.
5. Let the Dish Rest
Once the scalloped potatoes are finished, resist the temptation to serve them immediately.
Allow them to rest for approximately 10 to 15 minutes.
This gives the sauce time to settle and thicken slightly. It also makes the potatoes easier to portion without the layers sliding apart.
Finish with a sprinkle of fresh parsley if desired.
Tips for Perfect Scalloped Potatoes
Slice the Potatoes Evenly
This is probably the most important preparation tip.
Uniform slices cook more evenly. Very thick pieces may remain firm while thinner pieces become overly soft.
Don’t Rush the Baking Process
Scalloped potatoes are a dish that benefits from gentle, thorough cooking. The potatoes need enough time to become tender and absorb the creamy sauce.
If your slices are slightly thicker than recommended, you may need to add extra baking time.
Season Every Part of the Dish
Potatoes have a mild flavor, so seasoning is important. Salt, pepper, garlic, onion, and herbs help keep the finished dish flavorful rather than bland.
Don’t Make the Sauce Too Thick
The sauce should coat a spoon but still be pourable. An overly thick sauce may not distribute evenly between the potato layers.
Let the Potatoes Rest
A short resting period makes a big difference. The sauce continues to set as the dish cools slightly, giving you creamier and more defined layers.
Should You Peel the Potatoes?
Peeling is completely optional.
For a classic, smooth-looking scalloped potato casserole, peeling is often preferred. However, leaving the skins on can save time and add a rustic appearance.
If you leave the skins on, scrub the potatoes thoroughly before slicing.
Thin-skinned varieties generally work better for an unpeeled version.
Can You Add Cheese?
Yes, although there is a distinction between traditional scalloped potatoes and cheesy potato gratins.
A classic scalloped potato recipe typically centers on potatoes and a creamy sauce without requiring cheese.
If you love cheesy potatoes, however, adding Parmesan, cheddar, Gruyère, or another melting cheese can create a richer variation.
For a simple homemade version, sprinkle a modest amount of grated cheese between the layers or over the top before baking.
Easy Flavor Variations
Once you have mastered the basic recipe, it is easy to create different versions.
Garlic and Herb Scalloped Potatoes
Increase the garlic slightly and add fresh rosemary, thyme, or parsley. This version pairs particularly well with roasted meats.
Cheesy Scalloped Potatoes
Add shredded cheddar or Gruyère between the layers for a richer, more indulgent side dish.
Bacon Scalloped Potatoes
Cooked, crumbled bacon can be scattered between the potato layers. The smoky flavor complements the creamy sauce beautifully.
Caramelized Onion Version
Add thinly sliced caramelized onions between the layers. Their natural sweetness creates a delicious contrast with the savory potatoes.
Spicy Scalloped Potatoes
For a little heat, add a small pinch of cayenne pepper or crushed red pepper flakes to the sauce.
What to Serve With Scalloped Potatoes
These potatoes are versatile enough to accompany many main dishes.
Serve them alongside:
- Roast chicken
- Baked chicken thighs
- Roast beef
- Pork tenderloin
- Grilled steak
- Turkey
- Baked ham
- Roasted vegetables
- Green beans
- A crisp garden salad
Because the potatoes are rich and creamy, a fresh vegetable or salad can provide a pleasant contrast.
Can You Make Scalloped Potatoes Ahead of Time?
Yes. Scalloped potatoes are a convenient choice when you are preparing a larger meal.
You can assemble the dish ahead of time and refrigerate it until you are ready to bake it, provided the ingredients and preparation method are handled safely.
If the assembled dish is cold when it goes into the oven, it may require additional baking time. Make sure the center is fully hot and the potatoes are tender before serving.
For the best texture, avoid leaving sliced raw potatoes exposed to air for an extended period because they can discolor.
How to Store Leftovers
Allow leftover scalloped potatoes to cool appropriately, then refrigerate them in a covered container.
They are generally best enjoyed within a few days.
To reheat, use an oven or microwave until the portion is thoroughly heated. A little extra milk or cream can help loosen the sauce if it has thickened considerably in the refrigerator.
Leftovers can make an excellent next-day side dish and may taste even more flavorful after the seasonings have had additional time to mingle.
Common Mistakes to Avoid
Cutting the potatoes too thick: Thick slices can take much longer to become tender.
Under-seasoning: Potatoes need enough seasoning to bring out their flavor.
Skipping the resting time: Serving immediately can result in a looser sauce.
Using excessive liquid: Too much milk or cream can leave the finished dish watery.
Baking at excessively high heat: Very high temperatures can cause the top to brown before the potato layers are cooked.
Not checking the center: The edges may look finished while the potatoes in the middle are still firm. Always test the center with a knife.
Frequently Asked Questions
What is the difference between scalloped potatoes and au gratin potatoes?
The terms are sometimes used interchangeably, but traditionally scalloped potatoes are made with thinly sliced potatoes and a creamy sauce, while potatoes au gratin typically include cheese and often have a more pronounced browned cheese topping.
Why are my scalloped potatoes still hard?
The potatoes may have been sliced too thickly, or the dish may simply need more cooking time. Oven temperatures can also vary, so test the center with a knife before removing the dish.
Can I use heavy cream instead of milk?
You can, although using only heavy cream creates a much richer dish. Combining milk and cream provides a creamy texture without making the sauce excessively heavy.
Can I make scalloped potatoes without cheese?
Absolutely. Cheese is not essential to traditional scalloped potatoes. The creamy sauce, seasonings, and potatoes provide plenty of flavor on their own.
Can I use a different type of potato?
Yes. Yukon Gold and Russet potatoes are particularly reliable, but other varieties can work. Keep in mind that potato varieties differ in starch content and texture, so the final result may vary.
How do I know when scalloped potatoes are done?
Insert a thin knife into the center of the dish. If it slides easily through the potato layers without significant resistance, the potatoes are ready.
Final Thoughts
These easy homemade scalloped potatoes are proof that a handful of everyday ingredients can create an incredibly satisfying side dish.
The combination of thinly sliced potatoes, creamy homemade sauce, savory seasonings, and a golden baked top makes this recipe suitable for everything from a casual family dinner to a special holiday table.
For the best results, focus on three simple things: slice the potatoes evenly, season the sauce well, and give the potatoes enough time to become completely tender.
Once you make this recipe a few times, you can easily adapt it with cheese, herbs, garlic, bacon, caramelized onions, or other favorite ingredients.
Whether served beside roast chicken, holiday turkey, juicy steak, or a plate of roasted vegetables, homemade scalloped potatoes bring warmth and comfort to almost any meal.
