What You’ll Need
Here’s what you’ll need to create this amazing Cheesy Au Gratin Potatoes Recipe. I’ve kept the ingredient list simple so it is as easy as possible for you.

- 2.5 pounds Yukon gold potatoes, peeled and thinly sliced: I prefer Yukon gold potatoes because they have a creamy texture that works really well in this Cheesy Au Gratin Potatoes Recipe.
- 1 medium yellow onion, thinly sliced: The onion adds a subtle sweetness and savory flavor to the dish.
- 4 tablespoons unsalted butter: Butter is essential for creating a rich and flavorful sauce.
- 1/4 cup all-purpose flour: The flour helps to thicken the sauce, creating a creamy consistency.
- 3 cups milk: I recommend using whole milk for the best flavor and texture.
- 1 teaspoon salt: Salt enhances the flavors of all the other ingredients.
- 1/2 teaspoon black pepper: Pepper adds a touch of spice to the Cheesy Au Gratin Potatoes Recipe.
- 1/4 teaspoon nutmeg: Nutmeg adds a warm, aromatic flavor that complements the cheese and potatoes perfectly.
- 2 cups shredded cheddar cheese: Cheddar cheese gives this dish a classic cheesy flavor.
- 1 cup shredded Gruyere cheese: Gruyere cheese adds a nutty, slightly sweet flavor that elevates the Cheesy Au Gratin Potatoes Recipe.
You’ll find everything you need for this Cheesy Au Gratin Potatoes Recipe at your regular grocery store. Feel free to adjust the amount of cheese to your liking. My family prefers a cheesier dish, so I sometimes add a little extra.
If you don’t have Gruyere cheese on hand, you can substitute it with Swiss cheese or Fontina cheese. The most important thing is to use a cheese that melts well and has a good flavor. Now, let’s move on to the instructions for making this delicious Cheesy Au Gratin Potatoes Recipe!
How to Make It
Follow these simple steps to make the best Cheesy Au Gratin Potatoes Recipe. It’s easier than you think!
- Preheat oven to 375°F (190°C). This ensures that the Cheesy Au Gratin Potatoes Recipe cooks evenly.
- Grease a 9×13 inch baking dish. This prevents the potatoes from sticking to the bottom of the dish.
- In a large saucepan, melt the butter over medium heat. Make sure the butter doesn’t burn.
- Add the flour and whisk constantly for 1-2 minutes until a smooth paste forms. This is called a roux, and it’s essential for thickening the sauce.
- Gradually whisk in the milk, salt, pepper, and nutmeg. Continue whisking until the sauce is smooth and starts to thicken.
- Remove from heat and stir in the cheddar cheese and Gruyere cheese until melted and smooth. This creates the creamy, cheesy sauce that makes this Cheesy Au Gratin Potatoes Recipe so irresistible.
- Arrange a layer of potato slices in the prepared baking dish. Overlap the slices slightly.
- Top with a layer of sliced onions. Spread the onions evenly over the potatoes.
- Pour about one-third of the cheese sauce over the potatoes and onions. Make sure the sauce covers everything evenly.
- Repeat layers of potatoes, onions, and cheese sauce twice more, ending with a layer of cheese sauce. This layering technique ensures that every bite is packed with flavor.
- Cover the baking dish with aluminum foil. This helps to prevent the top from browning too quickly.
- Bake for 45 minutes. After 45 minutes, remove the foil and bake for another 15-20 minutes, or until the potatoes are tender and the top is golden brown and bubbly. You’ll know your Cheesy Au Gratin Potatoes Recipe is ready when a fork easily pierces through the potatoes.
- Let the Cheesy Au Gratin Potatoes Recipe rest for 10-15 minutes before serving. This allows the sauce to thicken slightly and makes it easier to slice and serve.
This Cheesy Au Gratin Potatoes Recipe typically takes me about an hour and a half from start to finish, including prep time.

Your Questions Answered
Here are some frequently asked questions about making Cheesy Au Gratin Potatoes Recipe:
Yes, you can! Assemble the dish up to the point of baking, then cover and refrigerate for up to 24 hours. Add about 15-20 minutes to the baking time to ensure the potatoes are cooked through. I will say though, there is nothing like having this fresh out of the oven!
No problem! You can substitute it with Swiss cheese, Fontina cheese, or even provolone cheese. Just make sure to use a cheese that melts well and has a good flavor.
While I prefer Yukon gold potatoes, you can also use Russet potatoes or red potatoes. Russet potatoes will give you a starchier result, while red potatoes will be slightly waxier.
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through.
I don’t recommend freezing this dish, as the texture of the potatoes and sauce may change when thawed. For best results, make it fresh.
Cover the baking dish with aluminum foil for the first 45 minutes of baking. This will help to prevent the top from browning too quickly. Then, remove the foil and bake for another 15-20 minutes, or until the top is golden brown and bubbly.
Absolutely! You can add other vegetables such as sliced mushrooms, cooked bacon, or chopped ham to the dish. Just add them in layers along with the potatoes and onions.
If your sauce is too thick, simply add a little more milk until it reaches the desired consistency. Whisk well to combine.
Yes, you can leave out the onions if your family doesn’t like them. However, I find that they add a nice flavor to the dish.
Add a pinch of cayenne pepper or a dash of hot sauce to the cheese sauce for a spicy kick.
These are some of the most common questions I get asked about this Cheesy Au Gratin Potatoes Recipe. Remember, cooking is all about experimenting and finding what works best for you and your family. Don’t be afraid to adjust the recipe to your liking and make it your own!
