Step‑by‑Step Instructions for Creamy Cheesy Potato Gratin
Step 1: Preheat and Prep
Begin by preheating your oven to 375°F (190°C). This allows the oven to reach the perfect temperature for baking your Creamy Cheesy Potato Gratin. Meanwhile, grab a mandoline or a sharp knife to slice the 2 pounds of potatoes thinly, aiming for even slices about ⅛ inch thick for optimal cooking.
Step 2: Sauté the Aromatics
In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add the finely chopped onion and sauté for about 5 minutes, stirring occasionally until they become translucent. This will build a flavorful base for the cream sauce. Next, mix in 2 cloves of minced garlic, 1 teaspoon of fresh thyme, ¼ teaspoon of nutmeg, salt, and pepper; cook for an additional minute until fragrant.
Step 3: Prepare the Cream Sauce
Stir in 2 cups of heavy cream to the sautéed mixture and bring it to a gentle simmer while continuously stirring. Allow it to bubble lightly for 2 minutes but do not let it boil. Once simmered, remove the saucepan from heat, allowing the flavors to meld together in this rich sauce destined for your creamy cheesy potato gratin.
Step 4: Layer the Potatoes
In a greased baking dish, lay down half of the sliced potatoes, overlapping them slightly for a cohesive layer. This ensures that each bite will contain deliciously creamy potato goodness. Once done, pour half of the cream sauce evenly over the potatoes, ensuring they are nicely coated.
Step 5: Cheese It Up
Sprinkle half of the grated Gruyère cheese over the first layer of potatoes and cream, letting it fall gently for even coverage. The melty Gruyère will bring unparalleled flavor to your Creamy Cheesy Potato Gratin. Repeat with another layer of the remaining sliced potatoes, followed by the remaining cream sauce, and finish by topping it with the rest of the cheese.
Step 6: Bake to Perfection
Place the assembled gratin in your preheated oven and bake for 1 hour and 10 minutes. You'll know it's ready when the top is golden brown and the potatoes are tender when pierced with a fork. This final baking transforms all the layered components into a luscious, creamy masterpiece.
Step 7: Rest Before Serving
Once baked, remove your creamy cheesy potato gratin from the oven and allow it to rest for about 10 minutes before serving. This resting time helps everything set a little, making it easier to cut and serve. Enjoy this comforting dish with family and friends!

How to Store and Freeze Creamy Cheesy Potato Gratin

Expert Tips for Creamy Cheesy Potato Gratin
- Potato Choice: Use starchy potatoes like Russets or Yukon Gold for a creamier texture. Avoid waxy potatoes, as they won’t yield the same lusciousness.
- Slice Evenly: Aim for uniform slices about ⅛ inch thick. Thicker slices may not cook through, leading to uneven results in your creamy cheesy potato gratin.
- Cheese Variety: Experiment with different cheese combinations beyond Gruyère. Cheddar adds sharpness, while mozzarella gives a gooey texture—play around to find your favorite!
- Resting Time: Allow the gratin to rest for 10 minutes before serving. This helps everything set, making it easier to cut and serve without falling apart.
- Bubbling Top: Broil for an additional 2-3 minutes if you want a golden, bubbling top. Keep an eye on it, as things can take a turn quickly!
Make Ahead Options
These Creamy Cheesy Potato Gratin are perfect for meal prep enthusiasts and busy weeknights! You can slice the potatoes and prepare the cream sauce up to 24 hours in advance. To do this, keep the sliced potatoes submerged in cold water to prevent browning and store the cream mixture in an airtight container in the refrigerator. When you’re ready to bake, simply layer the prepped ingredients in the baking dish, add the cheese, and bake as directed. This way, you’ll have a comforting meal ready with minimal effort, and it’ll be just as delicious as if made fresh!
