Description

The outside bakes to a golden, crunchy crust while the interior stays buttery and soft. It’s elegant enough for dinner guests and comforting enough for a weeknight family meal.

What’s Special About This Galette

This galette borrows the visual appeal of a classic French tart but swaps pastry for paper-thin potato slices. That swap creates a rustic, refined dish that showcases the humble potato’s versatility. With layers of aromatic garlic and herbs plus a hint of Parmesan, every bite is flavorful and balanced.

Ingredients

Use the following to make one 10-inch galette:

• 2 pounds medium unpeeled Yukon Gold potatoes — scrubbed and sliced about 1/8-inch thick for even cooking
• 1/4 cup grated Parmesan cheese
• 1 tablespoon cornstarch — helps bind the layers
• 1 teaspoon salt
• 1/4 teaspoon ground black pepper
• 3 tablespoons extra-virgin olive oil
• 3 tablespoons unsalted butter, melted — divided use
• 1/2 cup finely chopped sweet onion
• 3 large cloves garlic, minced
• 1 tablespoon fresh thyme, chopped — plus extra for garnish
• 3/4 teaspoon fresh rosemary, chopped — plus extra for garnish
• 3/4 teaspoon lemon zest — for a bright finish

Optional substitutions: Swap Parmesan for a dairy-free alternative or omit it if needed. For a deeper garlic note, substitute roasted garlic for raw minced garlic.

Instructions

Step 1: Prep the potatoes

1. Preheat the oven to 425°F (220°C).
2. Using a mandoline or a very sharp knife, slice the potatoes about 1/8-inch thick. Arrange the slices in a single layer between paper towels and press gently to remove excess surface moisture — this helps achieve crispness.

Step 2: Prepare the Parmesan mixture

1. In a small bowl, combine the grated Parmesan, cornstarch, salt, and pepper. Toss briefly so the cornstarch and cheese coat the salt and pepper evenly — this mixture will help season and bind between layers.

Step 3: Make the garlic-onion base

1. Heat 3 tablespoons olive oil and 1 tablespoon melted butter in a well-seasoned 10-inch cast-iron skillet over medium heat.
2. Add the chopped onion and minced garlic and cook, stirring frequently, until softened and translucent but not browned, about 2–3 minutes.
3. Stir in the chopped thyme, rosemary, and lemon zest. Transfer the mixture to a heatproof bowl so the skillet is clear for layering.

Step 4: Layer the galette

1. Grease the bottom and sides of the skillet with 1 tablespoon melted butter.
2. Arrange one-quarter of the potato slices in concentric overlapping circles to form the first layer.
3. Spread one-third of the garlic-onion mixture over the potatoes and sprinkle with one-third of the Parmesan mixture.
4. Repeat the layering two more times, finishing with a final overlap of potato slices. Brush the top with the remaining 1 tablespoon melted butter.

Step 5: Cook and bake

1. Place the skillet over medium-high heat and cook the layered potatoes for about 5 minutes, occasionally turning the pan slightly to prevent sticking and to develop a base crust.
2. Remove the skillet from the heat, cover tightly with foil, and bake in the preheated oven for 25 minutes.
3. Carefully press down on the foil to compress the galette, then remove the foil and bake uncovered for an additional 20–30 minutes, or until the potatoes are tender throughout and the bottom is golden brown.

Step 6: Serve

1. Allow the galette to rest briefly, then loosen the edges with a spatula and invert the galette onto a serving platter so the crisp bottom becomes the top. Garnish with extra thyme and rosemary if desired. Slice and serve warm.

Helpful Tips

• Uniform slices: A mandoline makes it easy to get consistent potato thickness for even cooking.
• Dry the potatoes well: Patting slices dry removes surface moisture that would otherwise steam and prevent browning.
• Use a cast-iron skillet: Cast iron develops a superior crust and holds heat evenly, which helps the galette finish beautifully in the oven.
• Season between layers: Distributing the Parmesan and garlic mixture between layers ensures every bite is flavorful.

Serving Suggestions

This galette pairs well with:

• Simple green salads dressed with a light vinaigrette
• Roasted or grilled meats such as chicken or lamb
• Sautéed greens, steamed asparagus, or roasted root vegetables
• A crisp, unoaked white wine or a light-bodied red for a heartier meal

Storage and Reheating

Refrigeration

Store leftovers in an airtight container in the refrigerator for up to 3 days.

Reheating

Rewarm in a 350°F (175°C) oven for 10–15 minutes to restore crispness. Avoid microwaving, which can make the potatoes soggy.

Freezing

Portion and wrap tightly in plastic wrap, then place in a freezer-safe container for up to one month. Reheat from frozen in the oven until warmed through and crisp.

Frequently Asked Questions (FAQs)

1. Can I use other potatoes?

Yes. Yukon Golds are ideal for their buttery flavor and creamy texture, but russets will also work; they may be slightly starchier and produce a different mouthfeel.

2. Can I make this vegan?

Yes. Replace the butter with a plant-based alternative and use a vegan Parmesan or omit the cheese altogether.

3. Can I assemble the galette ahead of time?

Yes. Assemble it in the skillet, cover, and refrigerate for up to one day. Bake just before serving to preserve texture.

4. What other ingredients can I add?

Try thinly sliced mushrooms, caramelized onions, or roasted peppers for variation. A drizzle of truffle oil after baking adds an indulgent finish.
