What You’ll Need For Scalloped Potatoes
- Potatoes – The best potatoes for scalloped potatoes are Yukon gold potatoes or red potatoes. They are thin-skinned, so they don’t require peeling, and they hold their shape well. Russet potatoes or Idaho potatoes can be used and taste great; however, they are more starchy and can break apart.
For the Sauce
- Onions – Use either white or yellow onion to flavor the sauce. Soften the onion in butter to bring out the natural sweetness.
- Flour and Butter – Flour and butter create a roux to thicken the sauce.
- Milk – Milk makes a creamy sauce without being too rich.
- Broth – Broth adds flavor and salt to the sauce.
- Seasonings – Since this is a classic scalloped potato recipe, the seasonings are simple. Salt, pepper, onion, and garlic—be sure to salt each layer of potatoes, too.
Variation: Add ½ teaspoon of dried thyme, crushed rosemary, or 1 tablespoon fresh parsley or chives to the sauce with the flour.
Cheese in Scalloped Potatoes
The word ‘scallop’ refers to how the potato is sliced, and generally, scalloped potatoes do not contain cheese. The difference between au gratin potatoes and scalloped potatoes is the cheese.
This recipe has a creamy onion sauce, while my Potatoes au Gratin have a cheese sauce. Of course, you can add cheese to this recipe (in the sauce or on top)—check the recipe notes for tips.
How to Make Scalloped Potatoes (overview)
Making scalloped potatoes from scratch takes time, but it is easy. There are four basic steps:
- Slice potatoes: Thinly slice the potatoes (a mandoline is helpful).
- Prepare sauce: Make the homemade sauce (recipe below).
- Assemble: Layer the potatoes and sauce in a baking dish.
- Bake: Cover and bake to make the potatoes tender. Uncover and bake to create a golden brown topping.
Busy Day Prep Tip
Scalloped potatoes will hold their heat for a long time, so they can be prepared up to 45 minutes early if needed as they retain heat well. Be sure to let them cool for at least 20 minutes before serving to allow the sauce to thicken.
Holly’s Tips for The Best Scalloped Potatoes
- Slice the potatoes thinly with a mandoline—about ⅛-inch thick.
- Season each layer of potatoes with salt and pepper.
- Cheese can be added to the sauce or the layers. Check the recipe notes.
- Cover with aluminum foil for the first 45 minutes so they steam and cook faster. Uncover towards the end for a golden brown top.
- Allow resting time for the sauce to thicken.
How To Prepare Scalloped Potatoes Ahead of Time
To make this scalloped potato recipe ahead, partially bake them and then finish baking on the day of serving. Partially baking ensures the potatoes don’t rust or turn grey.
- Prepare the recipe as directed below and bake covered for 50-60 minutes.
- Leave them covered and cool completely on the counter. Refrigerate for up to 48 hours.
- On the day of serving, remove from the fridge at least 30 minutes before baking. Bake uncovered for about 35 to 40 minutes or until heated through.
To freeze scalloped potatoes, cook them part way (about 25 minutes less than the recipe requires). Cool completely, then cover tightly and freeze. To cook, thaw the potatoes in the fridge overnight and follow the directions below, adding 20 minutes to the covered cooking time.
Leftovers, Storage & Freezing
Store leftover scalloped potatoes in the fridge for up to 4 days. They can be reheated in the microwave or oven. Chopped scalloped potatoes make great breakfast potatoes cooked until crisp in a nonstick skillet.

Scalloped Potatoes
Ingredients
- ¼ cup salted butter
- 1 large yellow onion diced
- 2 cloves garlic minced
- ¼ cup all-purpose flour
- 2 cups milk
- 1 cup chicken broth
- 1¼ teaspoon salt divided
- ½ teaspoon black pepper divided
- 3 pounds Yukon gold potatoes or red potatoes, *see notes, sliced about ⅛-inch thick
Instructions
- Preheat the oven to 350°F. Grease a 9×13-inch baking dish and set aside.
To Make the Sauce
- In a large saucepan, melt the butter over medium-low heat. Add the onion and garlic and cook until the onion begins to soften, about 3 to 4 minutes. Stir in the flour and cook for 2 minutes more.
- Combine the milk and broth. Gradually add it to the flour mixture, whisking until smooth after each addition. It will be very thick at first; continue adding a little bit of liquid at a time while whisking.
- Once all of the liquid has been added, increase the heat to medium and bring to a boil while whisking. Stir in ½ teaspoon salt and ⅛ teaspoon pepper and let the sauce boil for 1 minute.
To Assemble the Potatoes
- Layer ⅓ of the potatoes in the prepared dish and season with ¼ teaspoon salt and ⅛ teaspoon pepper. Pour ⅓ of the cream sauce over top.
- Repeat the layers, including salt and pepper, ending with sauce. Cover tightly with aluminum foil and bake for 45 minutes.
- Uncover and bake for an additional 35-45 minutes or until golden brown and potatoes are tender. Broil for 3-4 minutes if desired.
- Allow the potatoes to rest for at least 20 minutes before serving.

Delicious! I added a sachet of sour cream & chive popcorn seasoning into the cream sauce which really elevated the dish!
Easy and very useful recipe, its just perfect . Thank you, I’ve been using your recipe last 2 yrs.ago and hubby just love it.
I double the recipe but it took 2+ hours to cook!
Love these recipes!
fantastic recipe! thank you! your site is one of my go-to’s, always a hit :)
Whoops! My question was for the potato au gratin.
The potatoes au gratin recipe is versatile so feel free to change up the cheeses to your liking (cheddar and gruyere is a great combo). I haven’t had the cheese burn in the bottom but generally bake on the middle rack. I hope that helps!
This was really good. A little time consuming, even with using a mandolin, but it was fun, making the stocks with the hubby. However, I did not care for my choice of cheeses. I used Gruyere and Swiss. The Gruyere was good, the Swiss not so much (super stringy) And I also used pre-shredded cheese, won’t be doing that again! My only problem was that the cheese sauce burned on the bottom. I didn’t think that would have happened since it was covered in foil for the first hour of cooking. I used a glass baking dish. Any thoughts on what might have happened?
