Each ingredient in this Cheesy Potatoes Au Gratin Recipe plays a key role in creating a luscious, creamy dish. Here’s a bit more on why these favorites work so well together and some shopping tips to nail this recipe.
- Russet Potatoes: Their high starch content helps achieve that creamy interior without turning mushy—you want sturdy slices that cook through but hold their shape.
- Garlic: Freshly minced gives you a fragrant depth without being overpowering; it infuses the cream beautifully.
- Butter: Melted into the cream, it lends richness and a silky texture to coat the potatoes.
- Heavy Cream: This is the star of the sauce, providing the creamy base that keeps everything luscious and dreamy.

- Herb Swaps: Rosemary or sage work beautifully instead of thyme if you're in the mood for a different aromatic profile.
- Cheese Choices: You can mix Gruyère with sharp cheddar or mozzarella for a bit of a twist on flavor and melt.
Step-by-Step: How I Make Cheesy Potatoes Au Gratin Recipe
Step 1: Prep Your Potatoes with Care
Start by peeling your russet potatoes, then slicing them thin—about ⅛ inch thick is just right. I like using a sharp chef’s knife or a mandoline for consistent slices because it helps the potatoes cook evenly and layer beautifully in the dish.
Step 2: Build Your Creamy Layers
Whisk together heavy cream, minced garlic, and melted butter in a small bowl. Then arrange a third of your potato slices in the baking dish. Pour in a third of the cream mixture, sprinkle some fresh thyme, salt, and pepper, and top with a third of the grated Gruyère cheese. Repeat twice more, but save the last bit of cheese for later.
Step 3: Bake Low and Slow
Cover the dish tightly with foil and bake at 350°F for about 1 hour to 1 hour and 15 minutes. Check by poking a knife in the center—it should pierce easily. This slow baking makes the potatoes tender and allows all flavors to meld without drying out.
Step 4: Finish with a Golden Crunch
Remove the foil and sprinkle the reserved Gruyère on top. Pop it back in the oven for 10-15 minutes until the cheese turns a gorgeous golden brown and starts bubbling. Let it rest for 5 minutes before serving to let everything settle.
Top Tip
Over the years, I’ve learned a few tricks that really elevate this Cheesy Potatoes Au Gratin Recipe — little things that make a big difference between good and unforgettable.
- Use a Mandoline: Getting those potato slices thin and even ensures a perfect, tender result every time—and prevents undercooked potatoes in the center.
- Don’t Skip the Rest: Letting the dish rest after baking allows the cream to thicken up just right so your au gratin isn’t runny.
- Double Up on Cheese at the End: I always hold back some cheese for topping because that final golden crust is what folks rave about.
- Foil Tightly: Covering well traps moisture to soften the potatoes as they bake without drying out your creamy sauce.
How to Serve Cheesy Potatoes Au Gratin Recipe
Garnishes
I love sprinkling a little fresh thyme or chopped parsley on top right before serving. It adds a pop of color and a fresh herbaceous note to balance the richness perfectly.
Side Dishes
This dish pairs beautifully with roasted meats like chicken or beef, or alongside a fresh green salad to cut through its richness. I often serve it with glazed carrots or steamed green beans for some crunchy contrast.
Creative Ways to Present
For special occasions, try making individual au gratin servings in ramekins. It’s a fun way to present this comfort food with a touch of elegance, and everyone gets their own cheesy crust masterpiece.
Make Ahead and Storage
Storing Leftovers
I like to cool leftovers completely before transferring to an airtight container. Stored in the fridge, the au gratin keeps well for up to 3 days. Reheat gently to keep that creamy texture intact.
Freezing
This dish freezes nicely if you want to prep ahead. Just assemble but don’t bake, then wrap tightly and freeze. When ready, thaw overnight and bake as usual, adding an extra 10-15 minutes to ensure the center is tender.
Reheating
I reheat leftovers in a moderate oven at 325°F, loosely covered with foil to avoid drying out, until warmed through. A quick broil at the end brings back a bit of that crispy cheese topping magic.
Frequently Asked Questions:
You can, but russet potatoes are preferred for their starchiness and texture which holds up well when sliced thin and baked. Waxy potatoes like red potatoes may become too soft or creamy, changing the texture of the dish.
Make sure to slice your potatoes evenly and not too thick. Using heavy cream and melting the butter into the sauce helps keep it creamy. Also, baking covered traps moisture, so the potatoes cook thoroughly without drying out. Letting it rest before serving helps the sauce thicken.
Absolutely! You can prepare the entire dish except for the final cheese topping, then cover tightly and refrigerate or freeze. When ready to serve, bake as directed, adding extra time if frozen. Adding the cheese topping before the final baking step ensures a fresh golden crust.
If Gruyère isn’t available, Swiss cheese is a great substitute due to its similar melting qualities and flavor profile. Other good options include Emmental or a mild sharp cheddar, but avoid super-strong or crumbly cheeses that won’t melt smoothly.
Final Thoughts
This Cheesy Potatoes Au Gratin Recipe is one I keep coming back to because it’s both a nostalgic comfort and a dish that always impresses. It’s surprisingly straightforward to tailor and make your own, and with a little patience, you get a rich, creamy, cheesy masterpiece every time.
