Ingredients for Perfect Au Gratin Potatoes
Essential ingredients for creamy, cheesy potatoes
To achieve perfect au gratin potatoes, you'll need a few key ingredients that create that creamy, cheesy delight we all crave. Start with 2 pounds of Yukon Gold potatoes, which offer a buttery flavor and ideal texture. For the rich sauce, gather 3 tablespoons each of butter and flour, some finely chopped yellow onion, and minced garlic for that aromatic base. The creamy mixture relies on 2 cups of whole milk and ½ cup of heavy cream. Don't forget 1.5 cups of shredded cheddar cheese—opt for block cheese for better melting—and ⅓ cup of grated Parmesan to elevate the dish. Finally, season with salt and pepper to taste.
Alternatives and substitutions
If you're looking to mix things up or need alternatives, consider these substitutions:

Step-by-step Preparation of Perfect Au Gratin Potatoes
When it comes to comfort food, perfect au gratin potatoes stand out with their cheesy goodness and creamy texture. Follow these straightforward steps to whip up a dish that will impress friends and family alike!
Preparing the potatoes
Start by selecting the right potatoes. Yukon Gold potatoes are a fantastic choice due to their moderate starch content and buttery flavor. Begin by peeling your 2 pounds of Yukon Gold potatoes and slicing them into rounds, about ⅛ to ¼ inch thick. This thickness ensures even cooking and the perfect creamy texture. As you slice, you might want to soak them briefly in water to prevent browning—just remember to drain and dry them before use!
Making the creamy sauce
In a large saucepan, melt 3 tablespoons of butter over medium-high heat. Add ½ cup of finely chopped yellow onion and sauté for about 5–6 minutes until softened and translucent. This step enhances the flavor base of your sauce. Stir in 2 cloves of minced garlic and cook for an additional minute.
Once fragrant, sprinkle in 3 tablespoons of all-purpose flour and stir to combine. This will help thicken the sauce. Gradually pour in 2 cups of whole milk and ½ cup of heavy cream, whisking continually to avoid clumps. Bring the mixture to a gentle boil, then reduce the heat and let it simmer until thickened. Finally, incorporate 1 ½ cups of shredded Cheddar cheese and ⅓ cup of grated Parmesan cheese, along with 1 ½ teaspoons of salt and optional pepper. Stir until everything is melted and smooth.
Combining ingredients
Now that your sauce is ready, it's time to bring everything together. Add the sliced potatoes to the saucepan and gently stir until they’re thoroughly coated with the creamy mixture. Make sure all potatoes are well-covered to ensure a beautifully unified flavor in each bite.
Baking the au gratin
Preheat your oven to 350°F (175°C). Pour the potato mixture into a 2-quart casserole dish and spread it evenly. Sprinkle the remaining Parmesan cheese on top to create a delicious, crispy crust. Cover the dish with aluminum foil to lock in moisture and bake for about 1 hour, or until the potatoes are fork-tender.
After an hour, remove the foil and continue baking for another 20 minutes, allowing the top to turn lightly golden brown and ensuring any excess moisture evaporates.
Finishing touches before serving
Once out of the oven, let your perfect au gratin potatoes sit for about 5 minutes before serving. If you opted for Yukon Gold potatoes, this resting period is crucial for absorbing excess liquid. For a touch of color and a hint of freshness, sprinkle with some chopped parsley before serving.
Enjoy the delightful layers of flavor and texture, and watch as your guests savor each mouthful of this comforting classic!

Variations on Perfect Au Gratin Potatoes
Adding Veggies for a Twist
Why not brighten up your perfect au gratin potatoes by adding some vegetables? Think about incorporating sautéed spinach, roasted butternut squash, or even thinly sliced zucchini. These additions not only boost nutritional value but also provide vibrant color to your dish. Plus, the sweetness of roasted veggies pairs beautifully with the creamy decadence of the potatoes, creating a delightful balance.
Experimenting with Different Cheeses
Cheese lovers rejoice! While the classic cheddar is a stunning choice, branching out can yield delicious results. Try mixing in creamy Gruyere or tangy brie for a rich flavor. A blend of Fontina and Parmesan can also add a gourmet touch. Just remember to keep that cheese melty—maybe opt for cheese that’s freshly shredded for better texture! Your au gratin experience will elevate to a new level with these variations.
