Cast Iron Potato Galette Recipe
There’s something undeniably satisfying about a dish that combines simplicity with elegance.

Whether you're aiming to impress guests or elevate a weeknight dinner, this recipe delivers on both taste and presentation.
How To Make a Potato Galette
Ingredients
2.5 lbs russet potatoes
12 tablespoons unsalted butter
2 teaspoons coarse kosher salt
Freshly ground black pepper, to taste
1 teaspoon fresh thyme leaves (optional)
Instructions
1. Preheat the Oven
Set your oven to 350°F (175°C) to get it ready for baking.
2. Clarify the Butter
In a No. 10 Chef Skillet, melt the butter over medium-low heat.
Once it starts bubbling and the foaming subsides, remove from heat.
Skim off any foam from the top.
Carefully pour the butter through a fine mesh sieve into a heatproof bowl, leaving the milk solids behind.
You should have about ½ cup of clarified butter.
3. Prepare the Potatoes
Peel the russet potatoes.
Using a mandolin or sharp knife, slice them into very thin rounds, about ⅛-inch thick.
4. Assemble the Galette
Without cleaning the skillet (the residual butter adds flavor), arrange half of the potato slices in concentric circles, starting from the center and working outward.
Pour half of the clarified butter over the arranged potatoes.
Season with 1 teaspoon of kosher salt, freshly ground black pepper, and ½ teaspoon of thyme leaves.
Repeat the layering with the remaining potato slices, butter, salt, pepper, and thyme.
5. Bake Covered
Cover the skillet with a lid or aluminum foil.
Place it in the preheated oven and bake for 30 minutes.
6. Bake Uncovered
After 30 minutes, remove the lid or foil.
Increase the oven temperature to 425°F (220°C).
Continue baking for an additional 30-40 minutes, or until the top is golden brown and the potatoes are tender.
7. Serve
Let the galette cool for a few minutes before slicing. Serve warm as a side dish to your favorite main course.

FAQs
Can I use a different type of potato?
Yes, while russet potatoes are ideal for their starch content and texture, you can also use Yukon Gold potatoes for a creamier consistency.
Do I have to clarify the butter?
Clarifying the butter removes milk solids, preventing burning and giving a cleaner flavor. However, if you're short on time, you can use melted unsalted butter, but watch closely to prevent burning.
Can I add cheese to the galette?
Absolutely! Adding grated Gruyère or Parmesan between the layers can enhance the flavor.
How do I store leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven to maintain crispiness.
Can I make this dish ahead of time?
Yes, you can assemble the galette a few hours in advance and refrigerate it. Bring it to room temperature before baking.
What can I use if I don't have a cast iron skillet?
A heavy-bottomed, oven-safe skillet or a baking dish can be used as an alternative, though cooking times may vary slightly.
