What are scalloped potatoes or Quick Potato Dauphinoise?

Scalloped potatoes are considered to originate from England where the word ‘scallop’ literally means thinly sliced. Scalloped potatoes feature thin slices of potatoes tucked into a casserole dish with onions, herbs, and garlic and generously blanketed under a creamy cheesy homemade sauce. The result is a delicious savory crispy and golden on-the-top scalloped potato casserole. 

Origins of scalloped potatoes 

The origin of scalloped potatoes can be traced back to the European culinary traditions, particularly those of France and Ireland. Both countries have their own versions of dishes that involve layering thinly sliced potatoes with cream or milk and baking them to create a comforting and delicious dish. 

In France, the dish “Gratin Dauphinois” hails from the Dauphiné region and is believed to be one of the earliest forms of scalloped potatoes. It consists of thinly sliced potatoes layered with milk or cream and seasoned with garlic, nutmeg, and other spices. The shallow baking dish is then baked until the potatoes are tender and the top forms a golden crust. This French classic has been enjoyed for centuries and remains a staple in French cuisine. Gratin dauphinoise is always one of everyones favorite meals, and a great dish on the holiday table. 

In Ireland, a similar dish known as “Potato Hotpot” or “Potato Bake” has been a part of traditional Irish cooking. It involves layering sliced potatoes with onions, butter, and sometimes cheese, before baking until the potatoes are tender and the top is golden and crispy. This creamy potatoes dish has been enjoyed by Irish families as a hearty and comforting side dish.

Scalloped potatoes throughout Europe

Over time, as European immigrants brought their culinary traditions to different parts of the world, variations of scalloped potatoes emerged in different cultures. In the United States, for example, scalloped potatoes became a popular dish, especially during holiday gatherings and family meals. American versions often include layers of cheese, making them even more indulgent.

The exact origin of scalloped potatoes is not definitively documented, but its presence in European cuisines suggests that it has been a beloved comfort food for centuries. Regardless of its exact origin, scalloped potatoes continue to be enjoyed around the world, offering a delicious combination of creamy, tender potatoes with a satisfyingly golden top.

Tips and tricks for making the best scalloped potatoes: The ultimate Au Gratin 

Tips for Perfect Scalloped Potatoes

    1.    Choose the Right Potatoes: Opt for starchy potatoes like Russet or Yukon Gold, as they hold their shape and absorb the creamy sauce well.

    2.    Uniform Slicing: Slice your potatoes evenly, around 1/8-inch thick, for consistent cooking and a beautiful layered presentation.

    3.    Prevent Browning: After slicing, place the potatoes in a bowl of cold water to prevent them from browning while you prepare the rest of the dish.

    4.    Flavorful Base: Sauté onions or garlic in butter before layering to infuse the dish with extra flavor.

    5.    Create a Creamy Sauce: For a classic sauce, warm milk or cream and whisk in grated cheese until smooth. For gluten-free options, use cornstarch to thicken.

    6.    Season Well: Layer the potatoes with generous sprinkles of salt, pepper, and herbs like thyme or rosemary.

    7.    Layering Technique: Arrange the potato slices in overlapping layers, ensuring each layer is coated with the creamy sauce.

    8.    Baking Temperature: Preheat your oven to 375°F (190°C) for a gentle and even bake.

    9.    Cover and Bake: Tent the dish with aluminum foil for the first part of baking to prevent excessive browning.

    10.    Golden Crust: For a crispy top, remove the foil during the last 15 minutes of baking to allow the top layer to turn golden.

Gluten free au gratin potatoes recipe Substitutes:

    1.    Flour Substitute: Use a gluten-free flour blend or cornstarch to thicken the sauce.

    2.    Breadcrumb Topping: Instead of breadcrumbs, try crushed gluten-free crackers or bread for a crispy topping.

    3.    Gluten-Free Cheese: Opt for a grated gluten-free cheese, such as cheddar or Gruyère, for a flavorful layer.

Classic Scalloped Potatoes: Tips and tricks

    1.    Creamy Base: Use whole milk or a mixture of milk and heavy cream for a rich, classic flavor.

Vegan Au Gratin: The main ingredients to make one pan scalloped potatoes recipe (Quick Potato Dauphinoise)

Potatoes – Yukon gold potatoes or red potatoes have tender thin skin that makes them ideal for making scalloped potatoes. They don’t require peeling and will hold the sliced shape well. Other baking potatoes can also work, but not all potatoes will hold the sliced shape while cooking. No matter what potatoes you use the casserole will taste delicious though. 

Onions – onions add freshness and depth to the dish. Traditionally, white or yellow onions are used to make scalloped potatoes, but I also like to use red onions or even leeks. I find that every type of onion goes well in this recipe.

Homemade vegan creamy cheese sauce – this quick easy vegan and dairy-free creamy sauce are simple and delicious. Featuring almond milk (or other plant milk of your choice), herbs, nutritional yeast, garlic, and cashew cream this delicious velvety sauce is luxuriously cheesy. It’s thickened with corn starch which also makes it a great gluten-free vegan creamy cheese sauce.

Herbs – we’re working with thyme, nutmeg, paprika, salt and pepper to get all the flavors of winter with a tiny hint of Yuletide. 

How to make the best easy vegan scalloped potatoes 

Making this easy plant-based scalloped potatoes recipe is very straightforward. All you need is a sauté pan to make the vegan cheese sauce and a deep dish pan or casserole dish for the potatoes.

Note: You can make these delicious plant based French potatoes Au Gratin in the oven, air fryer, instant pot, or slow cooker, just like the classic potatoes. To do so, simply make the vegan cheese sauce and use the vegan ingredients; then otherwise follow the cooking instructions listed on the recipe card for the classic potatoes au gratin.

Let’s break down how to make plant-based scalloped potatoes step by step

  • Preheat oven to 400F (200 Celsius). 
  • Peel or scrub the Potatoes and slice them thinly. You can use a food processor for this step to speed up the process.

Making the vegan cheese Sauce:

  • Melt the vegan butter in a pan and add diced onions and garlic. Sauté for a few minutes while stirring occasionally.
  • Next, pour in almond milk and season with salt, paprika, thyme, nutritional yeast, and nutmeg. Add the vegetable stock, and cashew cream. Stir to combine and bring the sauce to a quick boil. 
  • In a small mixing bowl, whisk together 1 1/2 tablespoons cornstarch with 3 tablespoons water. Whisk the cornstarch mixture a little at a time into the sauce to thicken it. Once all the cornstarch has been combed with the sauce, remove it from the heat and set aside.

Making the scalloped potatoes casserole 

For the scalloped potatoes we want thinly sliced potatoes. You can use a food processor with a slicer to get thin and even potato slices in seconds…or you can use a handheld slicer (a mandoline) if you have one. Don’t have either? Don’t worry. You can also just do thinly sliced potatoes by hand (that’s what I usually do and it works great although it’s more time-consuming).

To peel or not to peel your scalloped potatoes?

That’s a matter of preference. If the peel looks nice and thin I usually leave it on…that’s part laziness and part knowing that most of the vitamins in the potatoes are right underneath the potato skin and we lose a lot of nutrients when we peel the potatoes. However, if the potato peel is thick and gnarly I always recommend peeling the potatoes because it will give you a more tender and melt-in-your-mouth delicious potato texture. 

How to make plant-based scalloped potatoes (Quick Potato Dauphinoise) step by step:

Layer the finely sliced potatoes in a baking pan or tray. Gently pour the sauce on top of the potatoes, trying to cover all the potatoes as you pour. Season with black pepper and top with vegan Parmesan cheese. Cover the pan with tin foil and bake the potatoes in the oven for 50-60 minutes, or until the potatoes gratin is golden on top. You can remove the tinfoil lid for the last 10-15 minutes of baking for extra golden crunchy goodness. Serve with a garnish of fresh herbs and enjoy.

Scalloped potatoes vs au gratin

Scalloped Potatoes vs. Au Gratin Potatoes: What’s the Difference?

Au gratin and Scalloped potatoes are two classic potato dishes that are often confused due to their similarities, but they have distinct differences in preparation, ingredients, and texture. Let’s dive into the key characteristics of each dish:

Scalloped Potatoes:

Scalloped potatoes are a simple and comforting dish made with thinly sliced potatoes that are typically layered in a baking dish. The layers are often seasoned with salt, pepper, and sometimes garlic. A creamy sauce, usually made with milk or cream, is poured over the layers of potatoes before baking. The dish is baked until the potatoes are tender and the top is golden brown and slightly crispy. Scalloped potatoes have a creamy and tender texture with a mild flavor, allowing the natural taste of the potatoes to shine.

Au Gratin Potatoes:

Au gratin potatoes, on the other hand, take scalloped potatoes a step further by adding a layer of cheese on top. The term “au gratin” refers to the crispy and golden-brown crust that forms on the top layer during baking. In addition to the creamy sauce, grated cheese is sprinkled over the layers of potatoes before baking. This cheese forms a flavorful and slightly crispy topping as it melts and browns in the oven. The result is a dish with a creamy interior and a cheesy, crispy exterior.

Key Differences:

1. Cheese Layer: The primary difference between scalloped and au gratin potatoes is the addition of cheese in au gratin potatoes. The cheese creates a crispy and flavorful crust on top.

2. Texture: Scalloped potatoes have a creamier and more tender texture due to the absence of cheese on top. Au gratin potatoes have a combination of creamy and crispy textures, thanks to the melted cheese.

3. Flavor Profile: While both dishes have a potato and creamy base, au gratin potatoes tend to have a richer flavor due to the addition of cheese.

4. Baking: Scalloped potatoes are baked until the potatoes are tender and the cream has thickened. Au gratin potatoes are baked until the cheese on top is melted and forms a crispy crust.

In summary, the main difference between scalloped and au gratin potatoes lies in the addition of cheese to the latter. While both dishes are comforting and delicious, au gratin potatoes offer an extra layer of flavor and texture with their cheesy and crispy topping. Whether you prefer the creamy simplicity of scalloped potatoes or the indulgent allure of au gratin potatoes, both dishes are perfect choices for warming and satisfying meals.

Notes and tips to make the best scalloped potatoes

How to prepare the scalloped potatoes (Quick Potato Dauphinoise) in advance 

To prepare vegan scalloped potatoes in advance simply make the scalloped potatoes following the recipe instructions. Once the potatoes are cooked, leave the casserole to cool on the counter. Once the scalloped potatoes are cold, you can store them covered in the refrigerator. I like to leave them in the casserole pan, cover them with cling film or tinfoil and leave them in the refrigerator overnight. Then you just reheat the oven to 350F (190 degrees Celsius), put the scalloped potatoes back in the oven covered with tin foil, and reheat for 20-25 minutes or until the potatoes are warmed all the way through.

How long to cook scalloped potatoes (Quick Potato Dauphinoise)

Scalloped potatoes or potatoes gratin needs to cook for nearly one hour, sometimes longer. The potatoes take a while to cook as they become tender and create creamy potato magic in the pan.

Will scalloped potatoes cook faster covered or uncovered?

Scalloped potatoes take a while to cook (usually around 1 hour). That makes it important to keep the potatoes covered for most of the cooking time, and only remove the cover for the remaining 1/3 baking time to allow the potatoes to become golden brown and crispy on top

How to reheat scalloped potatoes in a microwave

To reheat scalloped potatoes in a microwave, place the potatoes on a microwave-safe plate. Reheat for 2 minutes at a high temperature. If the potatoes are still cold in the center, stir them around and reheat them for 1 more minute. Repeat the process by heating for 1 minute at a time until the potatoes are heated all the way through.
Serve with a little drizzle of olive oil for extra deliciousness.

Tips to make the best vegan cheese sauce

Dairy-free plant milk options to make a vegan cheese sauce

I like to use almond milk and cashew cream to get the most luxurious creamy thick sauce. But there’s plenty of other great dairy-free choices that work just as well. Here’s my top picks
– Oat milk and oat cream 
– Coconut milk and coconut cream
– Soy milk and soy cream
– Rice milk and soy cream

Herbs

we are working with ground nutmeg, paprika, thyme, black pepper, and garlic to season this delicious scalloped potato casserole. You can use fresh or dried herbs to make scalloped potatoes. Both work equally well. I like to use dried herbs in the winter because it’s much easier to get, and the flavor is great with dried herbs.

Dinner ideas with scalloped potatoes: What to serve with scalloped potatoes 

Frequently Asked Questions 

Can I substitute potatoes with sweet potatoes?

Absolutely. You can easily make scalloped potatoes using sweet potatoes. The cooking time will reduce a bit, so you need to keep an eye on when they are ready. Note: sweet potatoes become more mushy when cooked than regular potatoes and won’t keep the sliced potato shape. It will still taste absolutely delicious though.

What kind of potatoes are best in scalloped potato casserole?

Russet potatoes, Yukon gold potatoes or other large baking potatoes are great to use to make scalloped potatoes. Any baking potatoes should work. I’ve also tried making scalloped potatoes with small fresh potatoes and it came out a treat.

How do I know when my scalloped potatoes are done?

The scalloped potatoes are done when you can easily pierce them with a knife or mush them with a fork. They should be tender all the way through. I like to test the potatoes by piercing them with the tip of a knife in the center of the casserole. If the potatoes in the center are done the dish is ready to serve.

Can potatoes be sliced ahead of time for scalloped potatoes?

Yes. If you want to slice potatoes ahead of time, simply store them completely covered in water in the refrigerator. You can store sliced potatoes covered in water for 12-24 hours in the refrigerator. 
Another option is to freeze the sliced potatoes right away. If doing it this way, it’s best to store the potatoes in the cooking pan, cover them with plastic wrap and freeze them. That way you can simply remove the plastic wrap, pour the sauce on top, and bake without even defrosting first. Sliced potatoes can be stored for 3-5 months in the freezer.

Freezing au gratin FAQs

Can you freeze scalloped potatoes

Yes, you can freeze potatoes au gratin, but there are a few things to keep in mind to ensure the best results:


1. Cool Completely: Allow the potatoes au gratin to cool completely before freezing. This will help prevent excess moisture from forming ice crystals and affecting the texture when you reheat them.

2. Portion and Package: If you’re planning to freeze individual servings, portion the potatoes au gratin into serving-sized containers or freezer-safe bags. Alternatively, you can freeze the entire casserole in a freezer-safe dish.

3. Wrap Well: Make sure the containers or bags are tightly sealed to prevent freezer burn. If using bags, squeeze out as much air as possible before sealing.

4. Label and Date: Clearly label each container or bag with the name of the dish and the date it was prepared. This will help you keep track of how long they’ve been in the freezer.

5. Freeze Quickly: Place the potatoes au gratin in the coldest part of the freezer and try to freeze them as quickly as possible to maintain their quality.

Reheating frozen scalloped potatoes

How to reheat frozen French augratin potatoes

Reheating: When you’re ready to enjoy the frozen potatoes au gratin, you can bake them from frozen. Preheat the oven to about 350°F (175°C), cover the dish with foil to prevent the top from burning, and bake for about 30-40 minutes or until heated through. For individual servings, you can reheat them in the microwave.

Texture Changes: It’s important to note that freezing and reheating potatoes au gratin can slightly alter their texture. The creamy sauce might become slightly separated, and the potatoes could be a bit softer. However, the flavor should remain intact.

Best Consumed Soon: While freezing is possible, potatoes au gratin are best enjoyed fresh. Freezing might impact the dish’s original texture and flavor to some extent.

Remember that while freezing potatoes au gratin is possible, the results might not be exactly the same as when they’re freshly made. It’s always a good idea to test freezing a small portion before freezing a larger batch, especially if you have specific expectations for the dish’s texture and flavor.

2. Place the desired amount of scalloped potatoes in an oven-safe dish. If they were refrigerated, you can let them sit at room temperature for about 15-20 minutes to take the chill off.
3. Cover the dish with aluminum foil to prevent the top from over-browning.
4. Bake in the preheated oven for about 20-30 minutes or until the potatoes are heated through. You can remove the foil during the last 10 minutes of baking to allow the top to crisp up a bit.

Microwave Method:
1. Transfer the desired amount of scalloped potatoes to a microwave-safe dish.
2. If you have a large portion, consider dividing it into smaller portions for more even heating.
3. Cover the dish with a microwave-safe lid or microwave-safe plastic wrap, leaving a small vent to allow steam to escape.
4. Heat the potatoes on medium power (50%) in intervals of 1-2 minutes, stirring in between, until they are heated through. Be cautious not to overcook, as the potatoes could become mushy.

Stovetop Method:
1. Place the desired amount of scalloped potatoes in a saucepan.
2. Add a splash of milk or cream to the potatoes to prevent them from sticking and to help rehydrate them as they heat.
3. Heat the potatoes over low to medium heat, stirring frequently, until they are heated through. Be gentle with the stirring to avoid breaking the potatoes.

Regardless of the method you choose, keep an eye on the potatoes to avoid overcooking or drying them out. It’s best to reheat scalloped potatoes gently to maintain their creamy texture and flavor.

Vegan French au gratin instructions

  • Preheat oven to 400F (200 Celsius). 

Peel or scrub the Potatoes and slice them thinly.
  • Melt the vegan butter in a pan and add diced onions and garlic. Sauté for a few minutes while stirring occasionally.
  • Next, pour in almond milk and season with salt, paprika, thyme, nutritional yeast, and nutmeg. Add the vegetable stock, and cashew cream. Stir to combine and bring the sauce to a quick boil. 

In a small mixing bowl, whisk together 1 1/2 tablespoons cornstarch with 3 tablespoons water. Whisk the cornstarch mixture a little at a time into the sauce to thicken it. Once all the cornstarch has been combed with the sauce, remove it from the heat and set aside.
    Note: at this point you can follow the instructions above if you want to make the plant based potato dish in instant pot, air fryer, or slow cooker.
  • Now, layer the finely sliced potatoes in a baking pan or tray. Gently pour the sauce on top of the potatoes, trying to cover all the potatoes as you pour. Season with black pepper and top with vegan Parmesan cheese.
    Cover the pan with tin foil and bake the potatoes in the oven for 50-60 minutes, or until the potatoes gratin is golden on top.
    You can remove the tinfoil lid for the last 10-15 minutes of baking for extra golden crunchy goodness.
    Serve with a garnish of fresh herbs and enjoy.
