Step‑by‑Step Instructions for Creamy Cheesy Potato Gratin

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that the Creamy Cheesy Potato Gratin will bake evenly, resulting in a perfectly golden top. A well-preheated oven is essential for achieving that bubbling, crispy layer we all love.

Step 2: Slice the Potatoes
Using a mandoline slicer, carefully slice your 2 pounds of potatoes into thin rounds, about ⅛-inch thick. The uniform thickness allows for even cooking and a creamy texture in every bite. Place the sliced potatoes in a bowl of cold water to prevent browning while you prepare the sauce.

Step 3: Prepare the Cheese Sauce
In a saucepan over medium heat, combine 2 cups of heavy cream (or béchamel sauce) with the finely chopped onion, minced garlic, 1 teaspoon of fresh thyme, and a pinch of nutmeg. Stir gently for about 5–7 minutes until the mixture is warm and fragrant, allowing the flavors to meld beautifully.

Step 4: Melt the Gruyère Cheese
Add 1 cup of Gruyère cheese to the warm cream mixture. Stir continuously for about 2–3 minutes until the cheese is melted and fully incorporated. The sauce should become creamy and smooth, full of cheesy goodness—this will coat your potatoes perfectly in the Creamy Cheesy Potato Gratin.

Step 5: Assemble the Gratin
In a greased baking dish, layer the sliced potatoes, slightly overlapping them for even coverage. Once you’ve created the layers, pour the creamy cheese sauce evenly over the potatoes, ensuring they are all well-coated. Visually, it should look luxurious and inviting.

Step 6: Add Extra Cheese Topping
Sprinkle additional cheese on top of your assembled gratin. This extra layer will brown beautifully during baking, creating a deliciously crispy finish. Use any good melting cheese to complement the Gruyère, enhancing the indulgence of your Creamy Cheesy Potato Gratin.

Step 7: Bake to Perfection
Place your baking dish in the preheated oven and bake for 1 hour and 10 minutes. As it bakes, watch for the top to turn golden and bubbly. The aroma wafting through your kitchen will be irresistible and signal that your comforting dish is nearly ready.

Step 8: Cool and Serve
Once baked, remove the Creamy Cheesy Potato Gratin from the oven and allow it to cool for about 10–15 minutes. This helps set the layers, making it easier to serve. The wait will be worth it, as each creamy, cheesy bite will warm your heart and nourish your soul.

Expert Tips for Creamy Cheesy Potato Gratin

Uniform Slices: Ensure potatoes are sliced uniformly for even cooking; a mandoline works wonders for this.

Layering Magic: Alternate layers of potatoes and cheese sauce for enhanced flavor and texture. Don't skip this step!

Watch the Bake: Keep an eye on the oven in the last 10 minutes to prevent burning the crispy cheese topping.

Rest Before Serving: Let the gratin cool for 10–15 minutes after baking for cleaner slices and intensified flavors.

Use Fresh Herbs: Fresh thyme is key; dried herbs may lack the vibrant flavor that makes the creamy cheesy potato gratin truly shine.

Make Ahead Options

These Creamy Cheesy Potato Gratin are perfect for busy home cooks! You can slice and soak the potatoes up to 24 hours in advance; just store them in a bowl of cold water in the refrigerator to prevent browning. Additionally, the cheese sauce can be prepared and refrigerated for up to 3 days. When you're ready to assemble, layer the potatoes in your baking dish, pour the chilled sauce over them, and sprinkle some extra cheese on top. Then, bake as directed, adding a few extra minutes to the cooking time if the dish is cold from the fridge. This way, you’ll enjoy a delicious, comforting meal with minimal effort on busy evenings!
