How to Make Au Gratin Potatoes

Step 1: Prep the Potatoes

Start by peeling your potatoes and slicing them thinly and evenly, about 1/8-inch thick. Consistent slices ensure even cooking and that perfect melt-in-your-mouth texture.

Step 2: Make the Cheese Sauce

In a saucepan, melt butter over medium heat, then whisk in flour to create a classic roux. Slowly add heavy cream while whisking to eliminate lumps. Once the sauce thickens, stir in shredded cheddar and gruyere cheese, garlic, salt, and pepper until smooth and melty.

Step 3: Layer the Dish

Arrange a layer of potato slices in your baking dish. Pour a bit of cheese sauce over them, then repeat layers until all potatoes and sauce are used, finishing with a generous layer of cheese on top for a golden crust.

Step 4: Bake Until Golden

Bake uncovered at 350°F (175°C) for about 60 minutes, or until the potatoes are tender through and the top is golden brown and bubbling. Let it rest for a few minutes before serving to set the sauce.

Pro Tips for Making Au Gratin Potatoes

• Use Starchy Potatoes: Russet or Yukon Gold potatoes hold sauce well and become perfectly tender without turning mushy.
• Slice Evenly: Consistent thickness ensures all potatoes cook uniformly every time.
• Don’t Skip the Roux: Thickening the sauce properly prevents watery or runny potatoes.
• Rest Before Serving: Let the dish cool briefly after baking so the sauce thickens for easier serving.
• Fresh Cheese Works Best: Pre-shredded cheese often contains anti-caking agents that can affect how well it melts.

How to Serve Au Gratin Potatoes

Garnishes

Top your freshly baked Au Gratin Potatoes with a sprinkle of chopped fresh parsley or chives for a pop of color and fresh flavor. Some grated Parmesan on top adds an extra savory touch before serving.

Side Dishes

This creamy and cheesy potato dish pairs beautifully with hearty proteins like roasted chicken, beef brisket, or grilled pork chops. It also complements vegetable sides such as steamed green beans, sautéed spinach, or crisp roasted Brussels sprouts for a well-rounded meal.

Creative Ways to Present

For an elegant twist, serve Au Gratin Potatoes in individual ramekins or small cast iron skillets. Layer small portions with microgreens or crispy shallots on top to add texture and visual appeal at your dinner table.

Make Ahead and Storage

Storing Leftovers

Place leftover Au Gratin Potatoes in an airtight container in the refrigerator. They’ll stay fresh for up to 3-4 days, making them perfect for next-day enjoyment or easy reheating.

Freezing

You can freeze this dish before baking. Cover tightly with aluminum foil and freeze for up to 2 months. When you’re ready, bake it from frozen, adding extra time until heated through.

Reheating

Reheat leftovers gently in the oven at 325°F (160°C) until warmed through to maintain the creamy texture. Microwaving works for a quick fix but may result in uneven heating or a loss of that crispy top layer.

FAQs

What is the difference between Au Gratin Potatoes and scalloped potatoes?

Au Gratin Potatoes include cheese in the sauce and on top, giving a richer, cheesier flavor, while scalloped potatoes typically use a cream sauce without cheese.

Can I use other types of cheese in Au Gratin Potatoes?

Absolutely! Cheese like mozzarella, fontina, or parmesan can be added or substituted to offer different flavors and textures.

How thin should the potato slices be?

Slices about 1/8-inch thick work best to ensure even cooking and a tender yet structured bite.

Is it necessary to peel the potatoes?

Peeling is traditional and gives a smooth texture, but leaving the skins on adds extra nutrients and a bit of rustic charm if you prefer.

Yes, swap dairy cream for coconut or almond milk-based cream and use vegan cheese alternatives to create a delicious dairy-free version.
