Step‑by‑Step Instructions for Creamy Cheesy Au Gratin Potatoes
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This initial step is crucial for ensuring that your Creamy Cheesy Au Gratin Potatoes bake evenly and come out perfectly golden. While the oven warms up, prepare your ingredients for a seamless cooking experience.
Step 2: Make the Roux
In a medium saucepan, melt 2 tablespoons of butter over medium heat. Once melted, stir in ½ cup of all-purpose flour to create a roux. Cook this mixture for about 1 minute until it turns a light golden brown, ensuring to stir continuously to prevent burning. This roux will be the flavorful base of your cheese sauce.
Step 3: Prepare the Cheese Sauce
Gradually whisk in 2 cups of milk to the roux, stirring constantly until the mixture thickens, about 3-5 minutes. You’ll know it’s ready when it coats the back of a spoon. Once thickened, add in salt, pepper, 1 cup of sharp cheddar cheese, and 1 cup of Gruyère cheese, mixing until the cheeses are completely melted and the sauce is smooth.
Step 4: Layer the Potatoes
In a greased 9x13 inch baking dish, begin layering your Creamy Cheesy Au Gratin Potatoes by placing half of the thinly sliced Yukon Gold potatoes at the bottom. Pour half of the rich cheese sauce over this layer, making sure to cover the potatoes evenly. This combination of layers will create that irresistible creamy texture.
Step 5: Complete Layering
Repeat the layering process with the remaining potatoes, placing the rest on top, then pouring the rest of the cheese sauce for a hearty finish. Ensure that every potato slice is submerged in the cheesy goodness. This will make each bite delightful and fully infused with flavor.
Step 6: Add the Crunch
Sprinkle 1 cup of breadcrumbs evenly over the top layer of cheese sauce. This crunchy topping is essential for elevating your Creamy Cheesy Au Gratin Potatoes, providing that wonderful contrast to the creamy layers below. The breadcrumbs will toast beautifully in the oven.
Step 7: Bake Covered
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 45 minutes at 375°F (190°C). Keeping it covered during the first stage of baking helps to steam the potatoes, ensuring they become tender while absorbing all the cheesy flavors.
Step 8: Bake Uncovered
After 45 minutes, carefully remove the foil to expose the top layer. Continue baking for an additional 15-20 minutes until the top is golden brown and bubbly. This final step reveals the beautiful, crispy layer that everyone loves in Creamy Cheesy Au Gratin Potatoes.
Step 9: Rest Before Serving
Once baked to perfection, take the dish out of the oven and let it rest for about 10 minutes. This resting period allows the flavors to meld beautifully and makes serving easier. Garnish with freshly chopped chives just before serving to add a pop of color and a touch of freshness.

Expert Tips for Creamy Cheesy Au Gratin Potatoes
-
Choose the Right Potatoes: Yukon Gold potatoes are ideal due to their creamy texture, but other waxy potatoes work well too. Avoid starchy potatoes like Russets for this dish.
-
Perfect Your Roux: Cook the roux just until it turns light golden brown to avoid a raw flour taste. Stir continuously to achieve that perfect creamy base for your cheese sauce.
-
Control the Cheese Melting: Add the cheese to the thickened sauce off the heat to prevent it from becoming grainy. This ensures a smooth and luscious cheese sauce for your au gratin potatoes.
-
Layer Wisely: Ensure that all potato slices are completely covered with cheese sauce for even cooking and flavor infusion. Skipping this step might lead to unevenly cooked potatoes.
-
Breadcrumb Technique: For extra crunch, consider toasting the breadcrumbs lightly in a skillet before sprinkling them on top. This will enhance the crispy texture of your Creamy Cheesy Au Gratin Potatoes.
-
Let It Rest: Allowing the dish to rest after baking helps it set up nicely, making serving easier and enhancing those fabulous flavors you’ve created.
Make Ahead Options
These Creamy Cheesy Au Gratin Potatoes are perfect for meal prep enthusiasts looking to save time during busy weeknights! You can slice the Yukon Gold potatoes and prepare the cheese sauce up to 24 hours in advance. For best results, keep the cheese sauce refrigerated and layer the potatoes in a greased baking dish, covering with plastic wrap to prevent browning. When you're ready to bake, simply remove the wrap, pour the sauce over the potatoes, and top with breadcrumbs. Bake according to the recipe instructions, and you'll enjoy the same creamy, cheesy goodness just with a little less fuss on your hands!

How do I store leftover Creamy Cheesy Au Gratin Potatoes?
For sure! Store any leftovers in an airtight container in the fridge for up to 3 days. When reheating, I recommend using either the microwave or placing the dish in the oven covered with foil until warmed through, ensuring the creamy texture remains intact.

Yes, definitely! You can freeze the unbaked assembled dish, tightly wrapped in plastic wrap and then foil, for up to 3 months. Make sure to thaw it overnight in the fridge before baking. And remember, if you're baking it straight from the freezer, add an extra 10-15 minutes to the baking time to ensure it's heated through and bubbly.
What if my cheese sauce does not thicken properly?
Very common! If your cheese sauce isn’t thickening, you might need to cook it a bit longer after adding the milk, stirring continuously.

Remember, patience and continuous stirring will yield a luscious sauce!
