1-First, preheat your oven to 400 degrees Fahrenheit to ensure the galette bakes evenly.

2-Next, melt the butter and mix it with the olive oil, garlic, chives, and parsley in a bowl for a flavorful coating.

3-Then, slice the potatoes thinly and evenly using a mandoline or sharp knife to promote uniform cooking and crispy edges, but be sure to handle your slicing tools carefully learn more about safety tips in this article on staying safe with a mandoline.

4-Place the sliced potatoes in a bowl and toss them thoroughly with the butter and herb mixture to coat each piece.

5-Grease an 8-inch cast iron skillet with the additional olive oil, making sure the bottom and sides are well covered.

6-Layer the potato slices in the skillet in concentric circles, overlapping each slice, and sprinkle salt and pepper between each layer for balanced seasoning.

7-Continue layering until all slices are used, then pour any leftover butter mixture over the top.

8-Bake uncovered for 60 to 80 minutes until golden and fully cooked; check doneness by gently pulling back the center potatoes to see if they are tender.

9-Finally, remove from the oven, garnish with additional fresh parsley, and slice into wedges for serving. This method, with its emphasis on even slicing and immediate assembly, helps achieve that creamy center and crispy edges we all love.
