This dish is the definition of simple elegance. With just three main ingredients, it is budget-friendly, forgiving, and perfect for impressing guests without a lot of fuss.

Ingredients

2 pounds Yukon Gold or russet potatoes, peeled and sliced paper-thin (about 1/8-inch thick)
1/2 cup unsalted butter, melted
1 teaspoon salt

Black pepper and fresh thyme are considered free pantry staples and can be added to taste.

Directions

Preheat your oven to 400°F (200°C). Generously butter a 9-inch cast-iron skillet or round baking dish.
Using a mandoline or sharp knife, slice the potatoes paper-thin. Keep them in a bowl of cold water to prevent browning until ready to use.
Drain and pat the potato slices completely dry with a clean kitchen towel.
In a large bowl, toss the potato slices with the melted butter and salt until evenly coated.
Arrange a layer of potato slices in a spiral pattern in the bottom of the prepared skillet. Continue layering, pressing down gently with a spatula after every few layers, until all the potatoes are used.
Pour any remaining butter over the top. Cover tightly with foil and bake for 40 minutes.
Remove the foil and continue baking for another 20 to 25 minutes, until the top is deeply golden and the edges are crispy.
Let the potato Anna rest for 10 minutes before carefully inverting onto a serving plate or slicing directly in the skillet.

Variations

Garlic Herb Potato Anna: Add 2 minced garlic cloves and 1 teaspoon dried thyme to the melted butter.
Cheesy Potato Anna: Sprinkle 1 cup of grated Gruyère or Parmesan between the layers.
Rosemary Potato Anna: Tuck fresh rosemary sprigs between the layers for a fragrant, herbal note.
Sweet Potato Anna: Substitute half the potatoes with sweet potatoes for a colorful twist.
Duck Fat Version: Use melted duck fat instead of butter for an extra rich, savory flavor.

Expert Tips

Slice the potatoes paper-thin. A mandoline makes this quick and ensures even cooking.
Dry the potatoes well. Excess moisture prevents the layers from crisping.
Press the layers down. Firmly packing the potatoes helps the cake hold together when sliced.
Use a cast-iron skillet. It conducts heat beautifully and gives the potatoes a gorgeous golden crust.
Let it rest. Resting for 10 minutes allows the layers to set, making slicing much easier.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a 375°F oven for 10 to 12 minutes to restore crispiness, or in a skillet over medium heat. Avoid the microwave, as it will make the potatoes soggy. This dish does not freeze well, as the texture can become grainy upon thawing.

Frequently Asked Questions

Can I make this ahead of time?Yes. Assemble it, cover, and refrigerate for up to 24 hours. Add 10 minutes to the covered bake time.
What potatoes work best? Yukon Gold and russet potatoes are ideal because of their starch content.
Can I use a different pan? Yes. A round cake pan or baking dish works, but a cast-iron skillet gives the best crust.
Why did my potatoes stick? The pan may not have been greased well enough. Use plenty of butter and a nonstick pan if needed.
