So, what exactly is this glorious dish? At its heart, a scalloped potato gratin is a beautiful symphony of thinly sliced potatoes baked in a creamy, savory sauce, usually with a generous helping of cheese. Think of it as the ultimate comfort food elevated. The “scalloped” part refers to how the potatoes are sliced – thinly and often overlapping, like little overlapping scales, which helps them cook evenly and absorb all that luscious sauce. The “gratin” comes from the French word “gratter,” meaning to grate, referring to the crispy, golden-brown cheesy crust that forms on top during baking. It’s rich, it’s decadent, and it’s just incredibly satisfying. This isn’t your grandma’s dry potato bake, oh no. This is a creamy, dreamy, cheesy masterpiece.
Why you’ll love this recipe?
Honestly, where do I even begin with why this scalloped potato gratin is a kitchen staple in my home? First off, the flavor is just out of this world. The potatoes become so tender, almost melting in your mouth, and they soak up all the cheesy, garlicky goodness of the sauce. It’s a flavor explosion that never gets old. Then there’s the simplicity. I know, it looks fancy, but trust me, it’s surprisingly easy to put together. You don’t need any fancy techniques, just a bit of slicing and stirring. What I love most about this is how budget-friendly it is too! Potatoes, cream, cheese – these are all relatively inexpensive ingredients, but they come together to create something that tastes like it came from a high-end restaurant. Plus, it’s so versatile! It’s fantastic as a side dish for almost anything, but honestly, sometimes I just eat it with a big salad and call it a meal. Compared to other potato dishes, this one just hits differently. It’s got that extra layer of creaminess and indulgence that makes it truly special. It’s the kind of dish that people rave about and ask for the recipe!
How do I make Scalloped Potato Gratin?
Quick Overview
The magic of this scalloped potato gratin lies in its straightforward assembly. You’ll start by thinly slicing your potatoes and then creating a luscious, creamy sauce that’s infused with garlic and herbs. We’ll combine these, layer them into a baking dish with plenty of cheese, and let the oven do the rest. The result is a bubbling, golden-brown dish of pure comfort that’s unbelievably easy to achieve, even on a busy weeknight. The key is in the details of the sauce and the thinness of the potato slices, which I’ll walk you through!
Ingredients
For the potatoes: For the potatoes: For the potatoes: For the potatoes: For the potatoes: For the potatoes: For the potatoes: For the
2.5 pounds Yukon Gold potatoes (about 4-5 medium-sized). I love Yukon Golds because they hold their shape beautifully and have a lovely creamy texture. Russets can work too, but they can sometimes get a bit too mushy for my liking in this dish. Make sure they’re fresh! No one likes sad potatoes.
For the Creamy Sauce:
3 cups heavy cream. This is non-negotiable for that ultra-rich, velvety texture. Don’t even think about using milk; it just won’t be the same! You *could* try a mix of half-and-half and whole milk if you’re really trying to lighten it up, but I find heavy cream is the star here. A splash of half-and-half could be used to thin it if it gets too thick.
1 cup whole milk. This helps to make the sauce a little less dense while still keeping it rich.
3 cloves garlic, minced. Fresh garlic is key for that wonderful aromatic punch. No powders here!
1 teaspoon salt. Adjust to your taste, but start here.
½ teaspoon black pepper. Freshly ground is always best, it makes a difference.
¼ teaspoon nutmeg. Just a tiny pinch adds a subtle warmth that complements the cream and cheese beautifully. You won’t taste it overtly, but it’s there!
For the Cheesy Goodness:
1.5 cups grated Gruyère cheese. This is my absolute favorite for its nutty, slightly sweet flavor and excellent melting properties. It’s what makes this gratin truly sing! If you can’t find Gruyère, a good quality sharp cheddar or a mix of Gruyère and cheddar is also fantastic.
½ cup grated Parmesan cheese. For that extra salty, sharp kick and to help with browning.

Step-by-Step Instructions
Step 1: Preheat & Prep Pan
First things first, let’s get the oven preheated to 375°F (190°C). This ensures it’s nice and hot when our potato mixture is ready. Now, grab a 9×13 inch baking dish. I like to give mine a really good buttering – use about 1 tablespoon of softened butter and spread it all over the bottom and up the sides. This prevents sticking and adds a little extra flavor. You can also use cooking spray if you’re in a hurry, but butter just feels right for this dish.
Step 2: Slice the Potatoes
This is probably the most crucial step for texture. You want to slice your potatoes *very* thinly and uniformly. A mandoline slicer is your best friend here. Seriously, if you don’t have one, consider it an investment for this recipe alone! Aim for about 1/8-inch thickness. If you don’t have a mandoline, a sharp knife and a lot of patience will do the trick. Try to keep them as consistent as possible so they cook evenly. I usually slice them right into a large bowl.
Step 3: Mix Wet Ingredients & Garlic
In a separate medium saucepan, combine the heavy cream, whole milk, minced garlic, salt, pepper, and that little pinch of nutmeg. Place this saucepan over medium heat. We’re not looking to boil it vigorously, just to warm it through and allow the garlic to infuse its flavor into the cream. Stir it gently as it heats. You’ll start to smell that wonderful garlic aroma – it’s a good sign!
Step 4: Combine & Gently Heat
Once the cream mixture is warm (not boiling!), carefully pour it over the sliced potatoes in your large bowl. Add about half of your grated Gruyère cheese and all of the grated Parmesan cheese to the bowl with the potatoes and cream. Now, using your hands or a gentle spatula, toss everything together to ensure every single potato slice is coated in the creamy, cheesy mixture. This is where the magic starts to happen!
Step 5: Layer into Baking Dish
Pour the potato and cream mixture into your prepared baking dish. Try to arrange the potato slices somewhat evenly, but don’t stress too much about perfection. They’ll settle and cook beautifully. Make sure all those delicious little bits of garlic and cheese are distributed throughout. If any potatoes are sticking out too much, gently tuck them in.
Step 6: Top with Remaining Cheese
Now for the crowning glory! Sprinkle the remaining Gruyère cheese evenly over the top of the potatoes. This is going to melt into a glorious, golden, bubbly crust. You want good coverage here for maximum cheesy goodness!
Step 7: Bake Until Golden and Bubbly
Cover the baking dish tightly with aluminum foil. Place it in your preheated oven and bake for 45 minutes. This initial covered baking time is crucial for allowing the potatoes to steam and become tender without drying out the top. After 45 minutes, carefully remove the foil. Continue baking, uncovered, for another 20-30 minutes, or until the top is beautifully golden brown and bubbly, and the potatoes are fork-tender when you gently pierce them. If the top starts browning too quickly, you can loosely tent it with foil again.
Step 8: Rest Before Serving
This is a tough one, but it’s important! Once it comes out of the oven, let your scalloped potato gratin rest for at least 10-15 minutes. This allows the sauce to thicken up beautifully and the flavors to meld. If you cut into it immediately, it will be a bit too soupy. Patience, my friends, is rewarded!

Step 9: Slice and Serve with Joy
After resting, slice into generous portions and serve. The smell alone will have everyone clamoring for a plate. It’s perfect on its own or alongside your favorite roast chicken, pork chops, or even a nice steak. Dig in and enjoy that creamy, cheesy perfection!
What to Serve It With
This scalloped potato gratin is so incredibly versatile, it’s become a go-to for so many occasions. For a truly decadent breakfast or brunch, I love serving a small portion alongside some crispy bacon or a perfectly poached egg. The richness of the potatoes complements the other breakfast staples beautifully. For a more elegant brunch spread, I’ll pair it with a light green salad with a bright vinaigrette to cut through the richness, and maybe some smoked salmon on the side. It’s just divine! As a dessert, hear me out! While it’s savory, a smaller, slightly less cheesy version can be a delightful savory course before a sweet dessert, especially if you’ve got a multi-course meal planned. Or, for those times when you just need pure comfort food, it’s absolutely heavenly as a main dish. Pair it with a simple side salad, some steamed green beans, or even just a crusty baguette to sop up every last bit of that sauce. My family loves it most with grilled chicken or pork tenderloin. It’s the kind of side dish that makes any meal feel special, turning an ordinary Tuesday night into a mini celebration.
Top Tips for Perfecting Your Scalloped Potato Gratin
Over the years, I’ve learned a few little tricks that take this scalloped potato gratin from great to absolutely unforgettable. For the potatoes, slicing them uniformly thin is *key*. I cannot stress this enough! If you have thick pieces, they won’t cook evenly with the thinner ones, and you’ll end up with a mix of perfectly tender and still-firm potatoes, which is never ideal. If using a mandoline, always, always use the safety guard. I’ve had a couple of close calls, and it’s really not worth it! When it comes to the sauce, don’t rush the heating process. Gently warming the cream and milk allows the garlic to infuse its flavor beautifully without scorching the dairy. Also, a tiny pinch of nutmeg is a game-changer; it adds a subtle warmth that just elevates everything. Don’t skip it! If your sauce seems too thick when you’re mixing it with the potatoes, don’t panic. Add a tablespoon or two more of milk or cream until it reaches a nice, pourable consistency. For the cheese, I highly recommend grating your own. Pre-shredded cheeses often have anti-caking agents that can make your sauce a bit grainy. Freshly grated cheese melts so much smoother and tastes so much better. When it comes to baking, if you notice the cheese is browning too quickly before the potatoes are tender, simply tent the dish loosely with foil. This will slow down the browning while allowing the potatoes to finish cooking. And remember that resting period after baking? It’s vital! It lets the sauce set up, making for cleaner slices and a more cohesive dish. Trust me on this one!
Storing and Reheating Tips
This scalloped potato gratin is so good, you’ll likely have leftovers, and thankfully, they store and reheat beautifully. For best quality, I recommend storing any leftovers in an airtight container in the refrigerator. It will keep well for about 3-4 days. Make sure it’s completely cooled before you put it in the fridge. When you’re ready to reheat, the oven is definitely the way to go for the best texture. Place a portion in an oven-safe dish and reheat at around 325°F (160°C) until heated through. This usually takes about 15-20 minutes. You can cover it loosely with foil if you notice the top getting too brown. If you’re in a real pinch for time, the microwave can work, but the texture might be a little softer and less crispy on top. Just heat in short intervals, stirring gently if possible, until warm. I don’t recommend storing this dish at room temperature for more than two hours, as it contains dairy and cheese, which can spoil. Freezing is also an option, though I find it’s best enjoyed fresh. If you do freeze it, wrap it very well in plastic wrap and then foil, and it should keep for about 1-2 months. Thaw it overnight in the refrigerator before reheating in the oven. The glaze, if you made one, would ideally be added after reheating to maintain its texture, especially if you’re serving it in individual portions.
