Step‑by‑Step Instructions for Potatoes Au Gratin
Step 1: Infuse Cream
In a medium pot, combine quartered shallot, smashed garlic, fresh thyme sprigs, heavy cream, and whole milk. Bring the mixture to a gentle simmer over medium heat, then cover and let it stand for 30 minutes. This infusion will enhance the creamy base for your Potatoes au Gratin, filling your kitchen with a warm aroma.
Step 2: Prep Baking Dish
While the cream mixture is infusing, butter a 13″ x 9″ baking dish generously, ensuring every corner is well-coated. Preheat your oven to 350°F (175°C). This step sets the stage for your beautiful Potatoes au Gratin to bake evenly, resulting in a golden, bubbling crust.
Step 3: Slice Potatoes
Peel the Yukon Gold potatoes, then slice them into 1/8″ thick rounds using a sharp knife or a mandoline for uniformity. Set the slices aside in a bowl, ready to absorb the creamy goodness that will envelop them in your Potatoes au Gratin. Even thickness ensures they cook evenly.
Step 4: Cook Potatoes
After the cream has infused, strain the mixture to remove the shallot, garlic, and thyme, returning the cream back to the pot. Add a generous pinch of kosher salt and the sliced potatoes, then simmer for about 4-5 minutes until they are fork-tender. This step allows the potatoes to start absorbing flavors before layering them in the dish.
Step 5: Layer and Bake
In the greased baking dish, begin layering the tender potato slices with the strained cream mixture, sprinkling Gruyère and Parmesan cheese between the layers. Continue until all ingredients are used. Bake the Potatoes au Gratin uncovered for 40-50 minutes, or until the top is golden brown and bubbly, signaling that it’s ready to come out of the oven.
Step 6: Rest Before Serving
Once baked, remove the Potatoes au Gratin from the oven and let it sit for about 5 minutes. This resting time allows the layers to settle, enhancing the flavors and making it easier to serve. You’ll have a stunning dish with a crispy top waiting to dazzle your guests!

Potatoes Au Gratin Recipe FAQs
How do I choose the right potatoes for Potatoes au Gratin?
Absolutely! Yukon Gold potatoes are perfect for this dish due to their creamy texture and ability to hold shape when baked. If you can’t find them, Russet potatoes can also work but may require a longer cooking time. Aim for potatoes that are smooth and free of dark spots or blemishes; these can affect the taste and texture of your gratin.
What is the best way to store leftovers of Potatoes au Gratin?
After enjoying your meal, make sure to store leftover Potatoes au Gratin in an airtight container in the refrigerator. They will stay fresh for up to 3 days. When reheating, I recommend using the oven to restore that delightful bubbly texture—just cover with foil to prevent the top from browning too much, and heat at 350°F (175°C) for about 20-25 minutes.
Can I freeze Potatoes au Gratin?
Yes, you can freeze Potatoes au Gratin! For best results, allow it to cool completely before transferring it to a freezer-safe container. It will last up to 2 months in the freezer. When you’re ready to enjoy it again, simply thaw in the refrigerator overnight, then reheat in a covered dish at 350°F (175°C) for 20-25 minutes to bring back that creamy goodness.
What should I do if my Potatoes au Gratin is too watery?
Very! If you find that your gratin is too watery after baking, it may be because the potatoes were not drained properly after simmering in the cream. Next time, ensure they are fork-tender but not falling apart before layering them in the baking dish. You can also try adding a bit more cheese or even a small amount of cornstarch mixed with cream before baking to thicken the sauce.
Are there any dietary considerations for Potatoes au Gratin?
Yes! If you have dietary restrictions or allergies, there are alternatives you might consider. For a dairy-free version, use plant-based cream and cheese substitutes. If you need to avoid gluten, all ingredients in the classic recipe are gluten-free, but always check for specific brands. Additionally, if you’re sensitive to garlic, you can simply omit it or reduce the amount used. Always feel free to personalize this dish to fit your dietary needs.
