Ingredients You’ll Need
This Creamy & Cheesy Au Gratin Potatoes Recipe uses simple ingredients that each play a critical role in the final masterpiece. From the buttery richness to the sharp tang of cheeses, every element contributes to the dish’s irresistible flavor and texture. Here’s a breakdown of everything you’ll need:
- 6–7 medium Yukon Gold potatoes: Their creamy texture and natural sweetness make them perfect for layering and absorbing the cheese sauce.
- ½ white or yellow onion: Adds a subtle sweetness and depth to the layers of potatoes.
- 2 tablespoons salted butter: Creates a rich base for the creamy sauce and adds richness.
- ¼ cup all-purpose flour: Used to thicken the sauce and give it that perfect gravy-like consistency; gluten-free alternatives work well too.
- 1½ cups unsweetened almond milk: Or regular whole milk for a creamier texture, providing the liquid foundation of the sauce.
- 8 ounces sharp cheddar cheese: Brings bold, tangy flavor and meltiness to the dish.
- ½ teaspoon garlic powder: Adds a subtle savory note enhancing the overall taste.
- ¾ teaspoon salt: Balances the flavors perfectly, with extra to taste.
- Freshly ground black pepper: Adds a gentle heat and earthy undertone.
- ½ cup Gruyere cheese: Or more cheddar, for that nutty, creamy layer that melts beautifully on top.
- ¼ cup grated Parmesan cheese: Offers a salty, sharp finish and helps create a golden crust.
- Fresh chopped parsley: For a burst of color and a fresh, herbaceous note as a finishing touch.
How to Make Creamy & Cheesy Au Gratin Potatoes Recipe
Step 1: Prepare Your Baking Dish and Potatoes
Start by preheating your oven to 375°F and greasing your baking dish with nonstick spray, butter, or oil. This step ensures the potatoes won’t stick and will brown beautifully. Then, slice your Yukon Gold potatoes thinly—about 1/8-inch rounds work best for even cooking. Thin slices are key because they soak up the creamy sauce and bake evenly without leaving a raw bite.
Step 2: Layer Potatoes and Onions
Arrange the potato slices in three slightly slanted rows in the baking dish, leaving tiny gaps to allow the sauce to pool between slices. Layer your onion slices both in between and on top of the potatoes. The onions add a sweet, mellow flavor that complements the richness of the cheese sauce.
Step 3: Make the Velvety Cheese Sauce
In a medium saucepan, melt your butter over medium heat. Gradually whisk in the flour, alternating with the almond or whole milk, until you form a smooth mixture. Keep whisking until it thickens to a gravy-like consistency—it only takes a few minutes but is vital for that perfect creamy texture. Reduce the heat, then stir in the sharp cheddar cheese, garlic powder, salt, and freshly ground black pepper. Taste and adjust the seasoning if needed because this sauce is the heart of the dish.
Step 4: Pour the Cheese Sauce Over the Layers
Evenly distribute the creamy cheese sauce over your layered potatoes and onions, making sure every slice is coated. This is where the magic starts as the sauce seeps into the potatoes, making every bite rich and flavorful.
Step 5: Bake Covered
Cover your dish tightly with foil and bake for 45 minutes. This step allows the potatoes to steam and start softening without browning the cheese topping prematurely.
Step 6: Add the Final Cheese Layer and Continue Baking
After removing the foil, sprinkle the Gruyere (or extra cheddar) and Parmesan over the top. Bake uncovered for another 30 to 45 minutes, or until the potatoes are fork-tender and the cheese on top has melted into a golden, bubbly crust that’s irresistibly crispy.
Step 7: Garnish and Serve Hot
Once baked, take your Creamy & Cheesy Au Gratin Potatoes Recipe out of the oven and finish with a sprinkle of fresh chopped parsley. It adds a lovely pop of color and a fresh note to lighten the richness just a bit. Serve immediately while warm and silky.
How to Serve Creamy & Cheesy Au Gratin Potatoes Recipe
Garnishes
Fresh chopped parsley is a classic and simple garnish that adds brightness and a splash of color to this hearty dish. For a little extra flair, try sprinkling some finely chopped chives or a pinch of smoked paprika to add a subtle smoky edge and vibrant contrast.
Side Dishes
This Creamy & Cheesy Au Gratin Potatoes Recipe pairs beautifully with roasted meats like chicken, pork, or beef, as its rich texture balances perfectly with savory protein. For lighter fare, serve alongside a crisp green salad dressed in a tangy vinaigrette to cut through the creaminess and provide a refreshing palate cleanser.
Creative Ways to Present
For a stunning presentation, bake the dish in individual ramekins for personalized servings. Alternatively, you can layer the potatoes and sauce in a cast-iron skillet, creating an impressive rustic look. Sprinkle extra cheese and herbs on top just before baking for an elevated golden crust that’ll wow your guests.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftovers of this Creamy & Cheesy Au Gratin Potatoes Recipe to an airtight container and store in the refrigerator. It will keep well for up to 4 days, making it perfect for meal prep or enjoying over several days without losing its deliciousness.
Freezing
You can freeze this dish after baking or before the final cheese topping step. Wrap the baking dish tightly with plastic wrap and aluminum foil or transfer portions to freezer-safe containers. Freeze for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator before reheating for the best texture and flavor.
Reheating
Reheat refrigerated or thawed portions in a 350°F oven covered with foil to keep moisture in, for about 20-30 minutes until heated through. For an extra crisp topping, remove the foil in the last 10 minutes. Microwaving is faster but may soften the crispy top.
FAQs
Can I use different types of potatoes for this recipe?
Yes! Yukon Gold potatoes are ideal for their creamy texture and natural buttery flavor, but you can also use Russet potatoes for a slightly fluffier bite. Just be sure to slice them thinly to ensure even cooking.
Is it possible to make this recipe dairy-free?
Absolutely! Use a plant-based milk like almond or oat milk, dairy-free butter alternatives, and vegan shredded cheeses that melt well. The recipe adapts nicely with these swaps, maintaining a delicious creamy texture.
How do I know when the potatoes are fully cooked?
The potatoes are done when you can easily pierce them with a fork or skewer with no resistance. Baking covered at first helps them soften through, while the final uncovered bake crisps up the topping perfectly.
Can I prepare the dish in advance and bake later?
Yes! Assemble the entire dish up through pouring the cheese sauce over the potato layers, then cover and refrigerate for up to 24 hours before baking. This makes it a convenient make-ahead meal.
What cheeses are best for the au gratin topping?
Traditional Gruyere and Parmesan cheeses give a nutty, sharp flavor and beautifully golden crust. Sharp cheddar adds richness and depth, and a combination of the three yields the best blend of meltiness and savory complexity.

- Letting the dish rest for 10 minutes after baking helps the sauce thicken slightly for easier serving.
