How to Make Potatoes Au Gratin
-
Preheat the oven to 375°F (190°C). Grease a baking dish with 2 tablespoons of softened unsalted butter to create a non-stick base for your gratin.
-
Slice the russet potatoes thinly using a mandolin for evenly cooked layers. Aim for about 1/8-inch thickness to ensure creamy, tender bites throughout.
-
Mix the heavy cream, shredded white cheddar, 4 tablespoons of grated Parmesan, and minced garlic in a bowl. Then, gently fold in the sliced potatoes, seasoning with salt and pepper to taste.
-
Layer the potato mixture neatly in the prepared baking dish, ensuring every slice is coated. Pour the creamy sauce over the stacked potatoes, dotting the top with the remaining butter for extra richness.
-
Cover the dish with foil and bake for 35-40 minutes. This step helps the potatoes steam and become tender while allowing flavors to meld beautifully.
-
Uncover the dish, sprinkle the remaining Parmesan on top, and bake for an additional 25-30 minutes, until the potatoes are fork-tender and the top is bubbling and golden.
-
Broil on high for 1 minute for that perfect crispy top, then cool for about 10 minutes before serving to let the dish set for easy slicing.
Optional: Garnish with fresh herbs like thyme for a pop of color and additional flavor!

Tips for the Best Potatoes Au Gratin
Uniform Slices: Ensure potato slices are even for consistent cooking. Taking the time to slice them uniformly results in perfectly tender layers.
Avoid Excess Moisture: Waxy potatoes contain too much water, which can make the gratin watery. Stick with russet potatoes for optimal creaminess.
Steam and Bake: Wrapping the dish tightly with foil allows potatoes to steam, ensuring they’re tender before uncovering for browning.
Resting Time: Let the gratin cool for 10 minutes post-baking. This resting period helps flavors meld and prevents burning when serving.
Customization Galore: Feel free to mix in caramelized onions or sautéed mushrooms for a twist on your classic Potatoes Au Gratin!
Storage Tips for Potatoes Au Gratin
Room Temperature: Refrigerate leftovers within 2 hours of baking to maintain freshness. Potatoes Au Gratin should not be left out for more than 2 hours.
Fridge: Store tightly wrapped in plastic wrap or in an airtight container for up to 3 days to keep the creamy layers intact and flavorful.
Freezer: For longer storage, freeze portions of the gratin in an airtight container for up to 2 months. When ready to use, thaw overnight in the fridge.
Reheating: Preheat the oven to 350°F (175°C) and reheat the gratin, covered, for about 20-25 minutes or until heated through, then uncover for a few minutes to crisp the top.

Potatoes Au Gratin Recipe FAQs
How do I choose the best russet potatoes for my gratin?
Absolutely! Look for russet potatoes that feel firm without any soft spots or blemishes. Ideal potatoes should be free of dark spots or excessive bruising, which can indicate age or decay. To ensure a creamy texture, pick potatoes that are on the larger side; these generally have a better starch content.
How should I store leftover Potatoes Au Gratin?
Very! After cooling, wrap your leftover Potatoes Au Gratin tightly in plastic wrap or transfer them to an airtight container. They can last in the refrigerator for up to 3 days. Just be sure to refrigerate them within 2 hours of baking to maintain their freshness.
Can I freeze Potatoes Au Gratin for later?
Absolutely! To freeze, let the dish cool completely, then cut it into individual portions. Wrap each portion tightly in plastic wrap and place them in an airtight container or heavy-duty freezer bag. They’ll keep well for up to 2 months. To reheat, thaw overnight in the refrigerator and then heat in the oven at 350°F (175°C) for 20-25 minutes until warmed through. Uncover for the last few minutes to re-crisp the top.
What should I do if my gratin is too watery?
Oh no! If your gratin turns out watery, it’s often due to using waxy potatoes or too much liquid. To prevent this, ensure that you use russet potatoes, which are high in starch and absorb cream well. If you find yourself with a watery gratin, try baking it uncovered for an extra 10-15 minutes. This helps evaporate excess moisture and allows the top to crisp up beautifully.
Are there any dietary considerations I should keep in mind?
Absolutely! If you’re cooking for someone with dairy allergies or lactose intolerance, you can substitute heavy cream with a plant-based alternative, such as coconut cream or cashew cream. For a vegan option, swap the cheese for nutritional yeast or a store-bought dairy-free cheese. Don’t forget to check for gluten-free options if necessary, though this recipe is naturally gluten-free!
Can I prepare Potatoes Au Gratin in advance?
Very! You can assemble the gratin up to 24 hours in advance. Simply prepare it as instructed, then cover it tightly and store it in the refrigerator. When you’re ready to bake, just add an extra 5-7 minutes to the initial baking time to ensure it heats through properly. This is perfect for busy days when you want to impress without the last-minute rush!
