Ingredient Snapshot
Choosing the right potatoes and cheese makes a world of difference here. I always use Russet potatoes for their starchy texture, which helps the layers meld beautifully without falling apart. For cheese, sharp cheddar gives a punchy flavor, but feel free to experiment with gruyère for a more French flair.
- Russet potatoes: Opt for firm, blemish-free potatoes for even slicing and a creamy texture when baked.
- Heavy cream: Provides richness and smoothness. Whole milk won't give the same luscious finish.
- Sharp cheddar cheese: Delivers that signature tang and a lovely melt. Avoid pre-shredded due to anti-caking agents.
- Butter: For greasing, helps prevent sticking and adds subtle flavor to the edges.

How to Make Creamy Potato Au Gratin Recipe
Step 1 - Prep & Season
First, preheat your oven to 375°F (190°C) and generously butter an 8×8-inch baking dish; this keeps the potatoes from sticking and adds a subtle richness around the edges. Peel and slice your Russet potatoes thinly - about ⅛-inch thickness is ideal. I find using a mandoline makes this quick and consistent, but a sharp knife works fine if you take your time. Make sure your slices aren't too thick, or they won't cook uniformly. In a bowl, whisk together the heavy cream with garlic powder, salt, and black pepper until the mixture is smooth and glossy - this will soak into the potatoes, infusing flavor throughout.
Step 2 - Build Flavor
Layer half of the sliced potatoes evenly in the prepared dish, overlapping just slightly. Pour half of your cream mixture over this layer, making sure it pools nicely between slices. Then sprinkle half of the shredded sharp cheddar cheese on top, watching the cheese melt into those nooks and crannies during baking. Repeat this process with the remaining potatoes, cream, and cheese. This layering sets the stage for that rich, satisfying texture you'll love. Resist the urge to stir or press down; letting the layers breathe keeps the au gratin light yet indulgent.
Step 3 - Finish for Best Texture
Cover the dish tightly with aluminum foil to trap steam and prevent the top from over-browning. Bake covered for 45 minutes. You'll notice a fragrant aroma beginning to fill your kitchen as the potatoes soften in the creamy sauce. After that, remove the foil and bake uncovered for an additional 15 to 20 minutes until the cheese bubbles vigorously and takes on a toasty golden crust. This step is key - it develops that lovely, slightly crispy top we all crave without drying out the creamy base. Let the dish rest for about 10 minutes before serving; this wait lets the sauce thicken just enough to hold its irresistible glossy layers.
Cook's Notes & Tricks
I like to slice potatoes in the morning if I'm prepping ahead - keep them submerged in cold water to prevent browning. When layering, avoid compacting too tightly; you want enough space for the cream to seep through. For best flavor, use freshly shredded cheddar instead of pre-shredded, as it melts smoother. Finally, don't skip the resting time - the flavors marry beautifully, and slicing is cleaner.
- Doneness Cue: Potatoes should be fork-tender and the top bubbling golden brown.
- Temperature Trick: Baking at 375°F lets the cream reduce gently without curdling.
- Make-Ahead Move: Assemble the dish a day ahead, cover tightly, and refrigerate before baking.
- Avoid This Pitfall: Don't slice potatoes too thick or they'll stay undercooked in the center.
Serve & Enjoy
Finishing Touches
I love adding a sprinkle of fresh thyme or chopped chives before serving to brighten up the richness of this creamy potato au gratin recipe. A small dusting of smoked paprika also adds a gentle warmth and a pop of color that makes each serving feel extra special. You'll notice how these little touches lift all the layers of flavor, turning a simple classic into a memorable centerpiece on your table.
Pairs Beautifully With
This creamy potato au gratin recipe pairs beautifully with roasted chicken or a simple pan-seared steak. I often serve it alongside steamed green beans or a crisp arugula salad dressed with lemon vinaigrette for freshness and texture contrast. The richness of the potatoes balances perfectly with light, bright veggies or juicy proteins to round out the meal.
Simple Plating Wins
For weeknight dinners, a rustic scoop straight from the baking dish onto your plate works wonderfully. On special occasions, use a spatula to create neat individual servings, garnishing with fresh herbs and a couple crispy potato chips or parmesan crisps on top for crunch. A casual wooden board or a simple ceramic dish always complements this cozy comfort food beautifully.
Make-Ahead, Storage & Reheat
Storing Leftovers
Leftovers store best in an airtight container in the refrigerator for up to 3 days. The texture remains creamy but solidifies a bit as the sauce cools. Simply reheat gently to bring back that luscious feel without drying it out.
Freezing Tips
This creamy potato au gratin recipe freezes nicely if covered tightly with foil or plastic wrap, for up to 2 months. Thaw overnight in the fridge before reheating. There may be slight changes in texture, but it still tastes delicious and satisfying.
Reheating Creamy Potato Au Gratin Recipe Without Drying Out
To reheat, I recommend warming it in the oven at 350°F (175°C) covered with foil for about 20-25 minutes, until warmed through. This keeps the creamy texture intact. If you're in a hurry, microwave on medium power in short bursts, covering loosely to trap moisture. Air fryer reheats well too - just cover with foil and heat 10-12 minutes at 350°F, checking frequently to avoid over-crisping.
