This Gruyere Potato Gratin is a creamy and cheesy dish that’s sure to warm your heart. Layers of tender potatoes meet rich Gruyere cheese, making every bite a delight!
I adore how this dish makes any meal feel a bit fancier. It’s like a warm hug on a plate! Don’t be surprised if you sneak an extra serving or two—it’s just that good! 😄
Key Ingredients & Substitutions
Yukon Gold Potatoes: These are my favorite for gratin. Their creamy texture and buttery flavor make them perfect. You can use Russet potatoes if you need a firmer texture, but avoid waxy potatoes like red potatoes, which don’t hold up as well.
Gruyère Cheese: This cheese gives a rich flavor and melts beautifully. If you can’t find it, Swiss cheese is a good substitute. For a sharper taste, try aged cheddar or even a mix of mozzarella and Parmesan.
Heavy Cream: While heavy cream is key for richness, you could use half-and-half for a lighter version. Just keep in mind that the gratin may be less creamy. Coconut cream can be a good non-dairy option, but it will change the flavor slightly.
Nutmeg: This adds warmth and depth to the dish! If you’re not a fan, you can skip it, but a pinch will elevate the flavor. You might also try a little cumin for a different twist.
How Do I Get My Gratin Perfectly Creamy Without Being Watery?
The key to achieving that creamy texture lies in how you layer and cook your potatoes. Make sure to slice them thinly and uniformly to ensure even cooking. Using a mandoline slicer can really help with this!
- Start with a buttered dish and layer your potatoes evenly with slight overlaps.
- Pour in your warm cream mixture gradually and make sure every layer of potatoes gets some moisture.
- Cover the dish with foil during the first part of cooking to retain steam, ensuring the potatoes soften without drying out.
- Once it’s done, let it sit for about 10 minutes before serving. This helps everything set nicely.

How Much Time Will You Need?
This recipe takes about 15 minutes to prep and approximately 1 hour to bake, making the total time around 1 hour and 15 minutes. Perfect for a cozy dinner or special occasion!
Step-by-Step Instructions:
1. Prepare Your Oven and Dish:
Start by preheating your oven to 350°F (175°C). While that’s heating up, take a 9-inch round baking dish or casserole dish and grease it well with the unsalted butter. This will help prevent the gratin from sticking.
2. Make the Cream Mixture:
In a medium saucepan, combine the heavy cream, whole milk, minced garlic, salt, freshly ground black pepper, and ground nutmeg. Heat this mixture gently over medium heat. You want it warm and infused with garlic but not boiling—so watch it closely! Once warm, remove it from heat and set aside.
3. Layer the Potatoes and Cheese:
Now it’s time to get layering! Start by arranging a layer of your thinly sliced potatoes at the bottom of the buttered dish. Overlap the potatoes slightly so they form a nice, even base. Next, sprinkle a portion of the grated Gruyere cheese evenly over the potatoes. Don’t be shy—this is where the flavor comes in!
4. Drizzle with Cream:
Pour a little of your warm cream mixture over the cheese and potatoes to moisten everything nicely. This helps bring all the flavors together!
5. Repeat the Layers:
Keep repeating the process of layering potatoes, Gruyere cheese, and drizzling with the cream mixture until you’ve used up all your ingredients. Make sure to finish with a layer of Gruyere cheese on top. This will create that lovely golden crust.
6. Bake the Gratin:
Cover the dish tightly with aluminum foil to keep the steam in, and bake in your preheated oven for about 45 minutes. After that, carefully remove the foil and bake for an additional 20-30 minutes until the top is golden brown, bubbly, and the potatoes are tender when you poke them with a fork.
7. Let it Rest:
Once baked, let your gratin rest for about 10 minutes before serving. This will help it set up a bit, making it easier to serve.
8. Garnish and Enjoy:
If you like, sprinkle some chopped fresh parsley or thyme on top for a touch of color and flavor. Now, dig in and enjoy your creamy, cheesy, and aromatic Gruyere Potato Gratin!
Can I Use Different Types of Potatoes?
Absolutely! Yukon Gold potatoes are ideal for their creamy texture, but you can substitute Russet potatoes if you prefer a firmer bite. Just avoid using waxy potatoes like red potatoes, as they won’t hold their shape as well.
Can I Substitute Gruyere Cheese?
Yes, if you can’t find Gruyere, Swiss cheese is a great alternative that melts well. For a sharper flavor, consider using aged cheddar, or a mix of mozzarella and Parmesan for a different taste.
How Do I Store Leftover Gratin?
Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. To reheat, simply warm it in the oven at 350°F (175°C) until heated through, or microwave individual portions for quick serving.
Is It Possible to Make This Ahead of Time?
Definitely! You can prepare the potato layers and cream mixture in advance, assemble the gratin in the dish, cover it tightly with foil, and refrigerate for up to 24 hours. Just add an extra 10-15 minutes to the baking time if cooking straight from the fridge.
