Step‑by‑Step Instructions for Crispy Parmesan
Step 1: Preheat the Oven
Begin by preheating your oven to 325°F (163°C). This ensures the temperature is just right for creating that perfect creamy base and golden, crispy topping as your Crispy Parmesan potato gratin bakes. Use an oven thermometer for accuracy, and prepare your kitchen with all necessary ingredients at hand.
Step 2: Infuse the Cream
In a medium saucepan over low heat, add the heavy cream, kosher salt, and minced garlic. Gently simmer the mixture for about 5 minutes, stirring occasionally to prevent sticking. You’ll notice the aroma of garlic filling the air—this is your cue to remove it from heat, allowing the flavors to intensify for your creamy base.
Step 3: Slice the Potatoes
Using a mandoline slicer, carefully cut your Yukon Gold or White potatoes into 1/8-inch thick slices. Aim for uniform thickness to ensure even cooking and a beautiful texture in your Crispy Parmesan potato gratin. As you slice, place the potatoes in a bowl of cold water to prevent browning.
Step 4: Prepare the Skillet
In a cast iron skillet, melt a couple of tablespoons of butter over low heat. Add the diced shallots and sauté for about 5 minutes until they are soft and slightly caramelized. This step adds a wonderful sweetness to your gratin, laying down a flavorful foundation for the potato layers to come.
Step 5: Layer the Potatoes
Arrange the sliced potatoes in a spiral pattern over the caramelized shallots in the skillet. This not only looks appealing but also allows for even cooking. Layer them gently, sprinkling a little salt and pepper as you go, ensuring every potato slice is included in the magic of the Crispy Parmesan gratin.
Step 6: Add the Cream Mixture
Carefully pour the garlic-infused cream mixture over the arranged potatoes, ensuring they are evenly coated. Use a spatula to gently press down the layers if needed, so the cream seeps into the potato slices. This step is crucial for achieving that rich and creamy texture that defines your Crispy Parmesan potato gratin.
Step 7: Cover & Bake
Cover the skillet tightly with aluminum foil and place it in the preheated oven. Bake for 1 hour and 15 minutes. The steam created will help cook the potatoes perfectly, making them tender. While baking, the aroma will start to fill the kitchen, heightening your anticipation for this comforting dish.
Step 8: Broil for Crispiness
Once the baking time is complete, carefully remove the foil. Generously sprinkle the Gruyere and Parmesan cheese along with fresh thyme over the top of the gratin. Place the skillet under the broiler for about 5 minutes, watching closely until the cheese turns golden and bubbly. This final touch creates that irresistible crispy topping.
Step 9: Serve Warm
Once broiling is done, remove the skillet from the oven and let it sit for a few minutes before serving. Scoop out portions of this delightful Crispy Parmesan potato gratin to serve warm, allowing the flavors to meld beautifully. Leftovers can be stored in the fridge, but there’s a good chance everyone will be coming back for seconds!

Expert Tips for Crispy Parmesan Potato Gratin
Even Slices Matter: Ensure your potatoes are sliced evenly at 1/8-inch thickness for consistent cooking and the perfect creamy texture.
Choose Fresh Garlic: Always use fresh minced garlic for an aromatic depth in your Creamy Garlic potato gratin; powdered garlic won’t deliver the same flavor impact.
Monitor Broiling: Keep a close eye on the broiler to prevent burning the cheese; that golden, crispy layer is the star of your dish!
Avoid Waterlogged Potatoes: After slicing, soak the potatoes in cold water only if you’re not layering immediately. This prevents excess moisture, keeping your gratin from becoming soggy.
Alternate Cheeses: Feel free to mix in different cheeses for unique flavors; just ensure they’re good melt choices to maintain that deliciously gooey texture.
