How to Make Potatoes au Gratin Recipe
Step 1: Prepare the Baking Dish and Oven
Start by preheating your oven to 375 degrees Fahrenheit and lightly buttering a 9×13 inch baking dish. This ensures your gratin won’t stick, and it sets the stage for even baking with a buttery undertone.
Step 2: Make the Cheese Sauce
In a medium saucepan over medium heat, melt the butter. Stir in the flour and cook for about one minute, creating a smooth roux—this is the thickening base that will make your sauce wonderfully creamy. Slowly whisk in the milk, salt, pepper, and nutmeg if using. Keep stirring constantly until the sauce thickens, roughly five minutes. Then remove the pan from heat and stir in 1 cup of shredded cheese and the Dijon mustard if you like that little boost of tangy richness, until melted and silky smooth.
Step 3: Layer the Potatoes and Sauce
Arrange half of your thin potato slices evenly in the buttered baking dish. Pour half of your luscious cheese sauce over this layer, spreading carefully so every slice gets coated. Then add the remaining sliced potatoes and cover them with the rest of the sauce, creating that irresistible cheesy blanket. Finish by sprinkling the remaining 1/2 cup shredded cheese and the Parmesan evenly on top to develop a golden crust while baking.
Step 4: Bake to Perfection
Cover the baking dish with foil to trap moisture and bake for 35 minutes. Then remove the foil and continue baking for another 20 to 25 minutes. You’ll want to see tender potatoes beneath a bubbly, golden-brown top. Allow it to rest for 5 minutes before serving—it lets all those amazing flavors settle perfectly.

Side Dishes
Potatoes au Gratin pairs beautifully with roasted meats like a juicy roast chicken or a tender pork loin. For a lighter alternative, a crisp green salad tossed with a tangy vinaigrette balances the richness perfectly. Don’t be afraid to get creative with steamed vegetables or even grilled asparagus to round out your meal.
Creative Ways to Present
If you want to impress guests or family, try serving this classic dish in individual ramekins or small cast iron skillets. Layering with additional ingredients like caramelized onions or fresh thyme between potato slices can add a gourmet twist. A light dusting of smoked paprika on top before baking gives a subtle smoky hint and an added pop of color.
Make Ahead and Storage
Storing Leftovers
Potatoes au Gratin keeps exceptionally well in the refrigerator. Store any leftovers in an airtight container, where it will stay tasty for up to 3 days. The flavors deepen overnight, making the second-day serving just as satisfying.
Freezing
If you want to freeze leftovers, place them in a freezer-safe container and cover tightly. It’s best consumed within two months to enjoy the full cheesy goodness. When you’re ready to eat, thaw overnight in the fridge before reheating.
Reheating
Reheat the gratin in the oven at 350 degrees Fahrenheit until warmed through, which usually takes about 20-25 minutes. This method helps preserve the crispy top while thoroughly warming the creamy interior. Microwaving works in a pinch, but you might lose some of the delightful texture.
FAQs
Can I use a different type of potato for this recipe?
While russet potatoes are ideal for their starchiness and ability to soften without becoming mushy, Yukon Golds can also be used for a creamier texture. Avoid waxy potatoes as they won’t achieve the perfect tenderness in this gratin.
What cheese works best for Potatoes au Gratin Recipe?
Gruyère is classic due to its nutty, melting qualities, but sharp cheddar is a delicious alternative that adds a bit more punch. Mixing cheeses like Gruyère with Fontina or even a mild mozzarella can create a complex flavor profile.
Is there a way to make this dish dairy-free?
You can substitute milk with unsweetened almond or oat milk, and use dairy-free butter and cheese alternatives. Keep in mind the flavor and texture will shift, but it can still be delicious and comforting.
How thin should I slice the potatoes?
About 1/8-inch thickness is ideal. Thin slices allow for even cooking and melding with the cheese sauce, but slices that are too thin may become mushy, while thicker slices take longer to cook through.
Can I add herbs or spices to customize the recipe?
Absolutely! Fresh thyme, rosemary, or a touch of smoked paprika work wonderfully. Just be mindful to keep additions balanced so the creamy cheese and tender potatoes remain the stars.
