How to Make Classic Au Gratin Potatoes

Step 1: Prepare the Potatoes

Peel and slice your potatoes into uniform, thin rounds about 1/8 inch thick. This ensures even cooking and creates the perfect tender layers within the dish.

Step 2: Make the Creamy Cheese Sauce

In a saucepan, melt butter and sauté minced garlic until fragrant. Stir in flour to form a roux, then slowly whisk in heavy cream, cooking until the sauce thickens pleasantly. Add in shredded cheddar cheese, salt, pepper, and a pinch of nutmeg, stirring until the cheese melts smoothly into the sauce.

Step 3: Layer the Potatoes and Sauce

Arrange a layer of potato slices in a greased baking dish, then pour over a portion of the cheese sauce. Repeat the layers until all potatoes and sauce are used, finishing with a generous cheese topping to create that irresistible golden crust.

Step 4: Bake Until Golden and Bubbling

Cover the dish with foil and bake at 350°F (175°C) for about 45 minutes. Remove the foil and bake for an additional 15 minutes until the top is bubbling and golden brown. Let it rest briefly before serving to set the layers.

Pro Tips for Making Classic Au Gratin Potatoes

• Consistent Slices: Use a mandoline slicer for evenly thin potatoes, ensuring uniform cooking.
• Don’t Skip the Roux: Thickening the cream sauce with flour prevents it from being too runny and helps it cling to potatoes better.
• Use High-Quality Cheese: Good cheddar makes a huge difference in flavor and melt, so choose one that’s sharp and fresh.
• Let the Dish Rest: Allow the au gratin to sit for 10 minutes after baking to thicken up, making it easier to cut and serve.
• Cover with Foil Initially: This prevents the top from burning while ensuring potatoes cook all the way through.

Make Ahead and Storage

Storing Leftovers

Place any leftover Classic Au Gratin Potatoes in an airtight container and refrigerate for up to 3 days. The flavors will deepen, and reheating will be just as delicious.

Freezing

You can freeze the dish either before or after baking. Cover tightly with foil or freezer wrap and store for up to 2 months. Thaw overnight in the refrigerator before reheating thoroughly.

Reheating

Reheat leftovers in the oven at 350°F (175°C) covered with foil until warmed through to maintain creaminess, or use a microwave for a quicker option if pressed for time.

FAQs

Can I use red potatoes for Classic Au Gratin Potatoes?

While red potatoes can be used, they tend to be waxier and less starchy than Russets or Yukon Gold, which means your dish may be less creamy and tender.

Peeling is traditional and results in a smoother texture, but you can leave the skins on if you prefer a rustic feel and added nutrients.

Can I prepare this recipe ahead of time?

Absolutely! Assemble the dish and refrigerate it for up to 24 hours before baking to make meal prep easier on busy days.

What cheese works best in Classic Au Gratin Potatoes?

Sharp cheddar is ideal for flavor and meltability, but you can mix in Gruyere or Parmesan for an extra savory twist.

How do I prevent the top from burning?

Covering the dish with foil during the first part of baking helps protect it, then removing the foil allows the top to become golden and bubbly without burning.
