Preparing Perfect Au Gratin Potatoes
When it comes to comfort food, few dishes can compete with au gratin potatoes. Creamy, cheesy, and satisfying, this dish is an all-time favorite. Here’s how to prepare the perfect au gratin potatoes in a few simple steps!
Prepping the Potatoes
Start by selecting your potatoes wisely. Yukon Gold potatoes are ideal for this dish due to their moderate starch content, making them perfectly creamy when cooked. Peel them and slice into ⅛ to ¼ inch thick rounds—getting the slices uniform ensures even cooking. As you prepare the potatoes, consider soaking them in cold water to prevent browning while you gather the other ingredients.
Sautéing the Onions and Garlic
Grab a large saucepan, and melt 3 tablespoons of butter over medium-high heat. Once the butter is sizzling, toss in ½ cup of finely chopped yellow onion. Sauté until the onions become soft and translucent—this usually takes about 5-6 minutes. Then, add 2 minced cloves of garlic and cook for an additional minute. This step is essential as it builds a savory foundation that truly elevates your perfect au gratin potatoes.
Creating the Creamy Cheese Sauce
Next, it’s time to build your cheese sauce! Sprinkle in 3 tablespoons of all-purpose flour after the onion and garlic are nicely sautéed. Stir it well and allow it to cook for a minute or two until it forms a paste. Gradually add in 2 cups of whole milk and ½ cup of heavy cream while stirring continually to prevent any lumps. Bring this mixture to a gentle boil, then reduce the heat and let it simmer until it thickens slightly. Finally, mix in 1.5 cups of shredded cheddar cheese, ⅓ cup of grated Parmesan cheese, and 1.5 teaspoons of salt. Stir until everything is melted and combined into a luscious sauce.
Combining Everything Together
Once your cheese sauce is ready, gently fold in the prepared potato slices. Ensure all the potatoes are well-coated; this creamy sauce is what makes au gratin potatoes so divine. Transfer this mixture to a 2-quart casserole dish, making sure it’s evenly spread out. Sprinkle the remaining Parmesan cheese on top for that golden, crunchy finish.
Baking to Perfection
Now for the best part—baking! Cover the casserole dish with foil and pop it into a preheated oven at 350°F for 1 hour, or until the potatoes are tender (you can test this with a fork). After that, remove the foil and bake for an additional 20 minutes to achieve that beautiful, lightly browned top. Let the dish sit for a few minutes before serving, as this will help thicken the sauce.
Voilà! You now have the perfect au gratin potatoes, ready to be enjoyed. Top with a sprinkle of chopped parsley for a pop of color, and dive into the creamy goodness that awaits. This dish is not only a crowd-pleaser but also a wonderful way to impress your friends at your next dinner gathering!

Au Gratin with Chicken Ham
