Best Kind of Potatoes for Au Gratin
The best potatoes for au gratin are high in starch and have a firm, dense texture. This will allow them to hold up well during cooking without turning mushy or falling apart. For best results, I recommend Russet or Yukon Gold.
- Russet potatoes are a great option for au gratin as they have a high starch content and are known for their firm texture.
- Yukon Gold potatoes are another good option for starchy potatoes with a buttery flavor and complement the creamy sauce in potatoes au gratin.
It’s important to slice the potatoes evenly for even cooking. A mandoline slicer or food processor with a slicing attachment makes the process easier and quicker. The best potatoes for au gratin are Russet or Yukon Gold potatoes for a deliciously creamy texture.

Substitutions
You can make several substitutions to the classic au gratin potatoes recipe to accommodate dietary restrictions or personal preferences. Here are some ideas:
- Use non-dairy milk and cheese: If you’re lactose intolerant or vegan, you can use non-dairy milk like almond or soy milk and non-dairy cheese like Daiya or Violife instead of regular milk and cheese.
- Use gluten-free breadcrumbs: If you’re gluten-free, you can use gluten-free breadcrumbs or omit them altogether.
- Use different types of potatoes: Instead of using traditional Russet or Yukon Gold potatoes, you can use sweet potatoes, red potatoes, or even turnips.
- Protein: Add protein to the dish by adding cooked chicken, ham, or shrimp to the potato layers. I prefer adding protein as the main dish rather than in the potatoes au gratin dish.
Variations
There are many variations to the classic au gratin potatoes recipe that you can try to change things up and add different flavors. Here are some ideas for the next time you make them:
- Add bacon or ham: Cook bacon until crispy, chop it up, and add it to the potato layers before adding the sauce and cheese. This will add a delicious smoky and salty flavor to the dish. You can add chunks of leftover ham as well.
- Use sweet potatoes: Swap out some or all of the potatoes for sweet potatoes to add a sweet and earthy flavor to the dish. Add some cinnamon or nutmeg to the sauce for extra warmth and spice.
- Add herbs and spices: Add fresh herbs like thyme, rosemary, or sage to the sauce for a fragrant and aromatic flavor. You can also add some garlic or onion powder for extra depth of flavor.
- Heavy Cream: use half heavy cream and half milk for a super-rich and creamy sauce.
- Use different cheeses: Instead of using the classic cheddar or gruyere cheese, try blending different cheeses like Mozzarella cheese, Monterey Jack, Gouda, or Blue Cheese. This will add different textures and flavors to the dish.
- Add vegetables: Add some vegetables like spinach, broccoli, or mushrooms to the potato layers for extra nutrients and flavor. You can also sprinkle some breadcrumbs on top for added crunch.
These are just a few ideas to get you started, but the possibilities are endless! Don’t be afraid to experiment and find your own favorite variation of au gratin potatoes.
Equipment
Storage
To store leftover au gratin potatoes, transfer them to an airtight container and store them in the refrigerator for 3-4 days.
To reheat the leftover au gratin potatoes, there are a couple of methods you can use:
- Oven method: Preheat the oven to 350°F (175°C). Place the leftover potatoes in an oven-safe dish and cover with foil. Bake for 15-20 minutes or until heated through. Remove the foil and bake for 5-10 minutes or until the top is crispy.
- Microwave method: Place the leftover potatoes in a microwave-safe dish and cover them with a lid or plastic wrap. Microwave on high for 1-2 minutes or until heated through.
Reheating the potatoes in the microwave may produce a softer texture, while reheating in the oven will produce a golden brown and crispy top layer.
Enjoy your reheated au gratin potatoes as a delicious side dish, or add some additional protein or vegetables to turn it into a main course.
Top tips
Here are some top tips to help you make delicious au gratin potatoes:
- Use a mandoline: Slicing potatoes uniformly can be difficult. Using a mandoline will help ensure that your potato slices are even and will cook evenly.
- Grate your own cheese from the block: This is key to a smooth sauce. Pre-shredded cheeses have caking agents that interfere with the creaminess of the sauce texture.
- Use a mixture of cheeses: Instead of just one cheese type, use a combination of different cheeses for added flavor and texture. Try using a variety of cheddar, gruyere, and parmesan cheeses to create the creamy cheese sauce.
- Don’t overcook the sauce: Be sure to cook until it thickens and coats the back of a spoon. Overcooking the sauce can cause it to break and become grainy.
- Season generously: Don’t be afraid to season the potatoes and sauce well with salt and pepper. This will help bring out the flavors of the dish.
- Let it rest: Allow the dish to rest for at least 10 minutes before serving. This will help the cheese set and the sauce to thicken, making it easier to serve and enjoy.
Following these tips, you can make a delicious batch of au gratin potatoes to impress your family and friends.
FAQs
Scalloped potatoes and au gratin potatoes are classic potato dishes that are popular in many parts of the world, but they are prepared differently and have some distinct differences. The main difference between scalloped potatoes and au gratin potatoes is that scalloped potatoes are typically prepared with a cream or milk-based sauce and do not have a crispy breadcrumb or cheese topping, while au gratin potatoes are covered with cheese to create a crispy crust.
Yes! You can make these cheesy au gratin potatoes up to three days ahead. Pour the sauce over the potatoes as directed, then cover the greased baking pan with foil- do not bake. Cover with aluminum foil and place in the fridge until ready to bake. Add 15-20 minutes for baking time if baking straight from the fridge.
The term “au gratin” comes from the French word “gratter” which means “to scrape” or “to grate,” referring to the crispy golden-brown crust that forms on top of the dish. “Au gratin potatoes” is a French term that refers to a dish of thinly sliced potatoes baked in a creamy sauce with cheese on top. The dish is typically baked until the cheese on top is golden brown and crispy, giving it a gratin-like texture.

Such a delicious recipe and really easy. Thank you so much for sharing. I paired it with your baked chicken recipe and our dinner was fantastic!!
Sounds wonderful! Happy you loved it!
I made these for Easter dinner and everyone loved them so much they begged me to make them the next Sunday as well!
So happy everyone loved them. They are always a hit!
I also made these potatoes for Easter dinner and what a hit they were! I just bought a new Mandoline so slicing was a breeze. Easy recipe to make and absolutely delicious. I will make these over and over. I used fresh raw full fat milk from a local farm. Yum!
Yay!! Happy everyone loved them as much as we do here. They are a big hit at any gathering. I love that you used fresh raw milk.
Elena, thank you for posting this incredibly delicious recipe. I followed it as written with Yukon Gold potatoes and used your substitution idea of half cream and half whole milk. I whisked the sauce for the stated time and added fontina, gruyere and parmesan. This dish was a hit at Easter dinner. I knew that if it tasted half as good as it smelled while baking, it would be delicious. It exceeded all expectations, and I received glowing compliments that I pass on to you. Thank you, again, for your contribution to our family gathering. The hostess was thrilled. I recently started following you on Instagram @cucinabyelena, and I received your email newsletter. I’m looking forward to trying more of your delicious recipes. P.S. I love the quality of your apron and pasta utensil I purchased from your website.
What a wonderful compliment! I am thrilled you loved the recipe and are loving the timeless products. Here’s to many more recipes. Enjoy.
Mmmm! Loved this au gratin. The cheeses were perfect. I did a little of it with sweet potatoes (and omitted the onions). Fantastic.
Wow- I love the addition of sweet potatoes. I want to try it.
Made these potatoes for Easter. Everyone loved them!
Hi Grace! Thrilled they were a hit with everyone 🙂
I made this recipe for Easter dinner and it was delicious.
Thank you! They are always a crowd-pleaser!
This recipe was a hit for Easter! Everyone loved it. I had never made my own cheese sauce etc before and directions were easy to follow. Loved the tips for cheese substitutions as I couldn’t find one of the main ones mentioned. Also did the half heavy cream half milk tip. I found the cooking time/temp to be perfect. Will definitely make again.
I made it in the AM and put it in the fridge until about 15 minutes before putting it in the oven. Prep wasn’t as long as I thought either.
Yay! I am glad the extra recommendations were helpful. It is an easy recipe to customize. I love to make it ahead of time like you did when I am making a large meal for a holiday.
