Step‑by‑Step Instructions for Crispy Parmesan
Step 1: Preheat the Oven
Begin by preheating your oven to 325°F (160°C). This temperature is ideal for gently baking your Crispy Parmesan Potato Gratin, ensuring the potatoes become tender and the cheese melts perfectly. While the oven heats up, gather your ingredients to set the stage for a smooth cooking experience.
Step 2: Simmer the Cream Mixture
In a small saucepan, combine 1 cup of heavy cream, 1 teaspoon of kosher salt, and 3 minced garlic cloves. Place the saucepan over medium heat and allow the mixture to simmer for about 5 minutes, stirring occasionally. This step infuses the cream with garlic flavor, enhancing the richness of your gratin. Remember to keep an eye on it to prevent boiling.
Step 3: Prepare the Potatoes
Using a mandoline slicer, thinly slice 5 medium Yukon Gold potatoes to about 1/8 inch thick. Aim for uniform slices to ensure even cooking throughout the Crispy Parmesan Potato Gratin. Once sliced, place the potatoes in a bowl filled with cold water to prevent browning while you prepare the next steps.
Step 4: Sauté the Shallots
In a well-greased cast-iron skillet, melt 1 tablespoon of butter over low heat. Add 1 diced small shallot and sauté for about 5 minutes until it softens and becomes translucent. The shallot adds a subtle sweetness to your gratin, so stirring occasionally ensures it caramelizes nicely without burning.
Step 5: Layer the Potatoes
Drain the sliced potatoes and layer them in a spiral pattern over the sautéed shallots in the skillet. As you layer, ensure you distribute them evenly for a memorable presentation. Carefully pour the garlic-infused cream mixture over the layered potatoes, allowing it to seep through.
Step 6: Bake the Gratin
Cover the skillet tightly with aluminum foil to lock in moisture, and place it in the oven. Bake for 1 hour and 15 minutes, ensuring the potatoes cook evenly. After this time, the potatoes should be tender when pierced with a fork.
Step 7: Broil for a Crispy Topping
Once baked, remove the gratin from the oven and set your temperature to broil. Remove the foil and sprinkle 1 cup of grated Gruyere cheese, ½ cup of grated Parmesan cheese, and 1 teaspoon of fresh thyme evenly over the top. Return the skillet to the oven and broil for about 5 minutes, watching closely until the cheese is golden and bubbly.
Step 8: Cool and Serve
Remove the gratin from the oven and let it cool for a few minutes. This resting period allows the layers to set beautifully, making it easier to serve. Slice into portions and enjoy your Crispy Parmesan Potato Gratin warm, and watch it delight your family and friends!

Make Ahead Options
These Crispy Parmesan Potato Gratin are perfect for busy weeknights or holiday gatherings, allowing you to enjoy the comforting flavors without the last-minute hassle! You can prepare the gratin up to 24 hours in advance by assembling it in the skillet and covering it tightly with foil before refrigerating. To maintain its quality and avoid sogginess, ensure the cream mixture is poured over the potatoes evenly. When you’re ready to serve, simply bake the gratin as directed, adding an extra 5-10 minutes to the initial cooking time if it’s coming straight from the fridge. Just like when made fresh, your family will love that it’s just as delicious, with the crispy cheese topping to make every bite irresistible!
