- Russet potatoes: Their high starch content ensures the slices soften and meld beautifully without becoming mushy.

- Heavy cream: Provides luscious creaminess that envelops each potato slice perfectly.
- Minced garlic: Adds aromatic depth, brightening the sauce’s flavor.

- Sharp cheddar cheese: The star ingredient that melts smoothly and develops that savory crust.
How to Make Homemade Au Gratin Potatoes Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 375º F. Greasing a 9×13 baking dish lightly ensures that your potatoes won’t stick and makes cleanup a breeze. This early step might seem simple, but a well-prepared dish sets the stage for everything that follows.
Step 2: Thinly Slice the Potatoes
After peeling the russet potatoes, slice them very thinly—about 1/8 inch thick. Using a mandoline or a sharp knife works well here. These thin slices are key to allowing the cream and cheese to soak every layer, ensuring tenderness and flavor in each bite.
Step 3: Whisk Together the Sauce
Combine melted butter, heavy cream, minced garlic, paprika, and onion powder in a large measuring cup or bowl. Whisk it vigorously until everything is evenly blended. This luscious, savory sauce will marry beautifully with the potatoes and cheese, giving the gratin its signature silky texture and tantalizing aroma.
Step 4: Layer Potatoes, Cheese, and Sauce
It’s all about the layers! Spread one third of the potato slices evenly in your baking dish. Sprinkle one cup of shredded cheddar cheese on top, then drizzle one third of the sauce over the cheese. Repeat with another third of the potatoes, cheese, and sauce. For the final layer, place the remaining potatoes first, followed by the remaining sauce, and top off with the rest of the cheese. Cover tightly with foil to seal in the moisture for perfectly tender potatoes.
Step 5: Bake Low and Then High
Bake the covered gratin at 375ºF for 60 minutes to cook the potatoes through. Then remove the foil and turn the heat up to 425ºF for 15 more minutes. This last step creates that beautiful golden, bubbly crust on top that is so irresistible. Allowing the dish to rest at least 10 minutes before serving lets the layers set beautifully and makes it easier to serve.
How to Serve Homemade Au Gratin Potatoes Recipe
Garnishes
While this dish is delicious on its own, a few simple garnishes can elevate it even further. A sprinkle of fresh chopped parsley or chives adds a fresh pop of color and a subtle herbaceous note that contrasts the rich cheese. For an extra touch of indulgence, a thin scattering of crispy bacon bits or a dash of smoked paprika can amplify the smoky, savory flavors beautifully.
Side Dishes
This Homemade Au Gratin Potatoes Recipe pairs wonderfully with roast meats like a tender beef roast, garlic butter chicken, or even honey-glazed ham. The creamy textures balance nicely with crisp green vegetables such as steamed green beans, roasted Brussels sprouts, or a light mixed green salad to brighten the meal.
Creative Ways to Present
For a special occasion, try presenting the gratin in individual ramekins for a charming personal touch. You can also experiment by mixing in finely chopped caramelized onions or a layer of sautéed mushrooms between the potatoes to add dimensions of flavor. For a fun twist, sprinkle breadcrumbs mixed with parmesan on top before the last bake to add crunch alongside the cheesy crust.
Make Ahead and Storage
Storing Leftovers
Leftover au gratin potatoes are a real treat the next day! Store them in an airtight container in the refrigerator for up to 3 days. As the flavors mellow overnight, they develop even more depth. Make sure to cool them completely before sealing the container to keep the texture intact.
Freezing
This dish freezes well, making it a perfect make-ahead option. After baking and cooling, portion out servings into freezer-safe containers or wrap the entire dish tightly with plastic wrap and foil. Freeze for up to 2 months. When you’re ready, thaw in the refrigerator overnight for best results.
Reheating
For reheating, warming in the oven is ideal to retain that crispy top. Set your oven to 350ºF, cover loosely with foil to prevent over-browning, and heat for 20-30 minutes until warmed through. Alternatively, microwave reheating works for a quicker option, but you might lose some crispness on top.
FAQs
Can I use a different type of cheese?
Absolutely! While sharp cheddar gives this recipe its distinct tang and melting quality, feel free to mix in Gruyère, Parmesan, or mozzarella for variations in flavor and texture. Just keep in mind the melting properties to maintain that perfect crust.
Do I need to peel the potatoes?
Peeling the potatoes creates a smoother texture and a cleaner presentation, but if you prefer a bit of rustic texture and extra nutrients, leaving the skins on is perfectly fine! Just be sure to wash them thoroughly before slicing.
Can I prepare this dish entirely ahead of time?
Yes! You can assemble the entire gratin the day before, cover it tightly, and refrigerate. When ready, bake it according to the temperature and time instructions, adding a few extra minutes if baking from cold.
What if I don’t have heavy cream?
If heavy cream is unavailable, you can substitute with a mixture of half milk and half melted butter to mimic the richness. Keep in mind the texture may be slightly lighter, but still delicious.
How do I prevent the gratin from becoming watery?
The key is in the thin, even slicing of the potatoes and using the right amount of cream and cheese. Baking covered first allows the potatoes to cook gently without drying out. Also, using russet potatoes helps avoid excess moisture compared to waxy varieties.

I truly believe this Homemade Au Gratin Potatoes Recipe is a timeless classic that deserves a spot on your recipe roster. It’s so simple, yet the results feel luxurious and special every time.
