Ingredients for Homemade Au Gratin Potatoes

Create the best side dish with this homemade au gratin potatoes recipe! It is full of potatoes, garlic, and butter, with a creamy base that has a cheesy topping throughout. You will love the flavor combination of these homemade au gratin potatoes and how simple they are to make!

  • Yukon gold potatoes – Yukon Golds are a MUST-have for this homemade au gratin potatoes recipe. You can also use russet potatoes. Both of these potatoes are thick and withstand heat and won’t become mushy.
  • Cloves garlic – One clove of fresh garlic gives this dish so much flavor.
  • Butter – The butter helps the potatoes and sauce not stick to the sides of the pan. You don’t want to melt butter for this homemade au gratin potatoes recipe. It is used for buttering the edges instead.
  • Liquid – Milk and heavy cream warmed together to make a creamy, rich cheese sauce for the potatoes to sit in.
  • Gruyère cheese – See below for why we use gruyere cheese. You can use cheddar cheese if you don’t have gruyere, but I would recommend sharp cheddar cheese.

Best Potatoes to Use for Homemade Au Gratin Potatoes Recipe

The best potatoes to use for the dish are gold potatoes. They are smooth and creamy in texture and have a sweet flavor. The inside of the potato is a golden color – thus the name “Yukon Gold.” But if you have russets on hand, by all means, use them! They are flaky and light and can make delicious homemade au gratin potatoes.

What is Gruyere Cheese?

I tried a variety of cheese in this dish that I had never tried before – gruyere cheese. The semi-soft cheese is especially flavorful and rich. You can find gruyere cheese in the specialty cheese section in your local grocery store. I found it near the Swiss cheeses. Gruyere cheese is slightly salty and has a creamy, nutty flavor. It is known as being one of the finest cheeses for baking. It melts beautifully and turns a golden brown when baked on top of a casserole or dish in the oven.

How to Make Easy Homemade Au Gratin Potatoes

It doesn’t take long to prepare and enjoy these homemade au gratin potatoes! This potato side dish recipe is so simple to make and comes together in minutes. You will love how delicious it is and watching your kids enjoy a vegetable they love!

  1. Prepare – First, slice the potatoes. You can use a mandolin slicer or a very sharp knife. You want to get the slices to about ¼ inch. Then, place the potato slices in a bowl of cold water to keep them from turning brown.
  2. Cut and rub – Cut the clove of garlic in half. Rub the two halves all over the bottom and sides of a glass baking dish. Then rub the butter over the dish as well.
  3. Bubble boil – In a small saucepan, heat the milk and heavy cream until it starts to bubble slightly. Remove from heat. Then, drain the water from the potato slices.
  4. Assemble – In the bottom of the baking dish, layer half of the potatoes and then sprinkle with salt and pepper. Pour half of the cream mixture over the potatoes and then sprinkle half of the cheese on top of that. Repeat another layer of potatoes, salt and pepper, cream, and cheese.
  5. Bake – Bake until the potatoes are tender and the cheese is golden brown on top.

Tips for Perfect Homemade Au Gratin Potatoes

Creamy and cheese homemade au gratin potatoes are just what you want with this dish! It is so simple to make and assemble every time. Follow these helpful tips for some help when assembling and even a recipe for making it in the slow cooker. These tips will make the best homemade au gratin potatoes!

  • Cookie sheet – A helpful tip for baking these in the oven is to place the casserole dish on a rimmed cookie sheet lined with foil. This will help with clean up if the potatoes boil over while cooking, or if it tips when putting them into or pulling them out of the oven.
  • Slicing – Slice potatoes between ⅛ to ¼ inch thick. Any thinner and the potatoes will be too crisp. Thicker slices won’t cook as evenly.
  • Layering – Layer potatoes by overlapping the slices slightly. This will help keep the sauce in place so it won’t all seep to the bottom.
  • Extra cheese – Add more cheese like cheddar to the Gruyere mixture for even more cheesy flavor.
  • Add-ins – We love to add cooked bacon chopped up, chives, or green onions for extra texture. Try it with different herbs like fresh thyme or rosemary for flavor variations!
  • Slow cook recipe – For a slow cooker option, see our recipe for Slow Cooker Au Gratin Potatoes.
  • Garnish – Garnish with parsley on top for a beautiful appearance!

Different Names for Homemade Au Gratin Potatoes

These potatoes au gratin are also called scalloped potatoes or Dauphinoise (dah-feen-was) potatoes. This dish originally comes from the Dauphine region in southeast France. My family has always called them homemade au gratin potatoes, but my husband grew up eating “scalloped”. It took us having quite a little argument to realize we were talking about the same recipe! No matter what you call them, these potatoes are sure to disappear quickly at your next gathering.

“This recipe has the perfect combo of flavors. So creamy and cheesy. Thank you!”

  1. I’ve never made this type of potato dish from scratch but, I’m gonna give it a try for our Thanksgiving dinner!!!

  2. 5 stars
    I have tried a bunch of different scalloped style potatoes, but hands down this dauphinoise potatoes is the best one I’ve ever had. It is for sure going to be on my menu for the holiday as well!

  3. I just put this in the oven for tonight’s dinner. It was very easy to make. Instead of rubbing the dish with garlic, I bashed a couple of cloves and let them steep in the simmering cream. I pulled the cloves out as I poured the warm cream over the potatoes. Smells divine and will be the perfect side for my glazed ham and Brussel sprouts.

  4. I just found your website and I am over the moon. The recipes are absolutely wonderful and easy to make. I am now a very happy cooker. Thank youvso much.

  5. I am from the Dauphine area, and I love this dish. The original recipe does not use any cheese, only potatoes, heavy cream and garlic for taste (lots of it). Some recipe stickler will add laurel leaves.
