Ingredients
Before we dive into the cooking, let’s gather our ingredients:
- 2 ½ pounds Yukon Gold potatoes (beautifully waxy and creamy)
- 1 ½ cups heavy cream (for that luscious texture—yes, please!)
- 1 ½ cups shredded Gruyère cheese (nutty and melty goodness)
- 1 cup shredded sharp cheddar cheese (for a tasty bite)
- 4 cloves of garlic, minced (fresh garlic adds more punch than powdered)
- 1 teaspoon fresh thyme leaves (herbaceous brightness)
- Salt and pepper to taste
- 2 tablespoons unsalted butter (for greasing your baking dish)
Make sure you pick good quality ingredients for the best flavor. Fresh herbs are always recommended, but if you’re in a pinch, dried could work as well!
Step-by-Step Instructions
Now, let’s get those layers of creamy, cheesy potatoes into the oven!
- Preheat your oven. Start by preheating your oven to 375°F (190°C). A hot oven means crispy, bubbling edges—yum!
- Prepare your baking dish. Generously butter a 9×13-inch baking dish to ensure your potatoes don’t stick while baking.
- Slice those potatoes. Using a mandoline or a sharp knife, slice the Yukon Gold potatoes into thin, even rounds—around ¼-inch thick. Uniform slices help everything cook evenly.
- Create your creamy mixture. In a bowl, combine the heavy cream, minced garlic, thyme leaves, and a good sprinkle of salt and pepper. Taste it and adjust seasoning as needed. This is the base of your creamy layers!
- Layer, layer, layer. Start placing a layer of potato slices in the bottom of your baking dish, overlapping them slightly. Pour over some of your creamy mixture and sprinkle a layer of Gruyère and cheddar cheese on top. Repeat this layering process until you’re out of potatoes and finish with a generous amount of cheese on top.
- Cover with foil. Tightly cover your baking dish with aluminum foil—this keeps the steam in so your potatoes cook perfectly!
- Bake it! Pop it in the oven and bake for 45 minutes. After 45 minutes, remove the foil and bake for an additional 30 minutes or until the top is golden brown and bubbly. This part is essential for getting those delicious crispy layers.
- Let it rest. Once out of the oven, allow it to cool for about 10-15 minutes. This setting time will help the layers firm up so you can slice them beautifully.
And there you have it—a gorgeous, comforting dish that’s sure to become a family favorite! Just a heads-up: don’t be tempted to rush this recipe; the resting time is crucial for the perfect slice!

Pro Tips & Variations
Want to switch things up a bit? Here are some fun twists and tips to make this dish your own:
- Cheese Swap: Try swapping the Gruyère for Fontina or Monterey Jack for a different flavor profile.
- Herb Fun: Experiment with different herbs like rosemary or chives for a fresh twist.
- Add Veggies: Sneak in some sautéed mushrooms or spinach between the layers for an extra veggie boost!
- Spice it Up: A pinch of cayenne or smoked paprika can add a delightful kick.
- Make it Gluten-Free: This recipe is naturally gluten-free, but do check your cheese labels to ensure no hidden gluten.
The possibilities are endless, and that’s what I love about this recipe! Each variation makes it uniquely yours.

Serving Suggestions
Now that your Potatoes Au Gratin are ready, let’s talk about how to serve this delectable side! Pair it with a fresh leafy green salad dressed in a light vinaigrette to cut through the richness. The crunch of the salad is the perfect contrast to the creamy potatoes.
You could also serve it alongside a juicy roast chicken or grilled steak for an elevated family dinner. And honestly, a crusty slice of rustic bread isn’t a bad idea either—it’s fabulous for scooping up all that cheesy goodness!
Don’t forget a nice glass of white wine—perhaps a crisp Sauvignon Blanc—to enjoy alongside your meal. Trust me; it’ll enhance that flavor explosion!
Storage Tips
Now, if you have leftovers (which, let’s be honest, is a rarity), here’s how to store your delicious creation:
- Refrigeration: Allow the au gratin to cool completely, then cover with plastic wrap or transfer it to an airtight container. It will keep well in the fridge for up to 3 days.
- Freezing: To freeze, cut the potatoes into portions and freeze in an airtight container or freezer-safe bag. It can be frozen for up to 2 months.
- Reheating: When ready to enjoy, thaw in the refrigerator overnight if frozen. Reheat in a 350°F (175°C) oven, covered with foil, until heated through—about 30 minutes for refrigerated and longer for frozen. You can remove the foil during the last 10 minutes to restore that glorious bubbly top!
FAQs
Can I use different types of potatoes for this recipe?
Absolutely! While Yukon Gold holds its creaminess beautifully, you can try Russet potatoes for a fluffier texture. Just keep in mind that they might absorb more liquid, so you might need to adjust your cream slightly.
Can I prepare this ahead of time?
Yes, you can prepare the layers ahead of time and assemble them in your baking dish. Just cover and store them in the fridge for up to 24 hours before baking. Just add a few extra minutes to the baking time if going from cold!
What’s the best way to slice the potatoes thinly?
A mandoline slicer is your best friend here! It makes uniform slices, which ensures even cooking. If you don’t have one, a sharp knife will do the trick—just take your time to keep the slices consistent!
How can I make this dish healthier?
You can substitute half of the heavy cream for milk or use low-fat cheese options. Throw in some spinach or other veggies to add nutrients and fiber without compromising flavor!
What’s the secret to preventing watery layers?
The key is to not skimp on the cheese and ensure your cream mixture is thick enough. Always allow your dish to rest before cutting; this will help it set and maintain those lovely layers!
