Leek and Potato Galette with Pistachio Crust
Ingredients
Dough:
- 1/2 cup raw pistachios
- 2 1/2 cups all-purpose flour
- 1 tsp kosher salt
- 1 cup unsalted butter chilled and cut into pieces
Filling and Assembly
- 1 tbsp olive oil more for drizzling
- 1 large leek white and pale-green parts only, halved lengthwise, thinly sliced
- 4 oz. fresh goat cheese
- 5 tbsp heavy cream
- 2 cloves garlic finely chopped
- kosher salt
- freshly ground pepper
- all-purpose flour for surface
- 4 tbsp coarsely chopped dill divided, plus sprigs for serving
- 2 large Yukon Gold (or similar) potatoes thinly sliced
- 1 large egg beaten to blend
- crushed pink peppercorns for serving (optional)
Instructions
Dough:
- Pulse pistachios in a food processor until coarsely ground. Add flour, salt, and sugar and pulse to combine. Add butter and pulse just until a coarse meal forms. With motor running, gradually stream in ½cup ice water and process until dough comes together. Transfer dough to a work surface; form into a ball, then flatten into a disk. Wrap in plastic and chill at least 30 minutes. Dough can be made 1 day ahead. Keep chilled.
Filling and Assembly
- Preheat oven to 400º. Heat 1 Tbsp. oil in a small skillet over medium-low. Cook leek, stirring occasionally, until softened but without taking on any color, about 5 minutes. Transfer to a plate. Mix goat cheese, cream, and garlic in a medium bowl to combine; season.
- Divide dough into 4 pieces. Roll out 1 piece of dough on a lightly floured surface to an 8" round; transfer to a parchment-lined baking sheet. Using an offset spatula, spread one-quarter of goat cheese mixture over dough, leaving a 1" border. Scatter 1 Tbsp. dill evenly over, then top with a thin layer of potato slices. Drizzle with oil;season with salt. Scatter one-quarter of leeks over potatoes. Fold edges of dough over filling, tucking and overlapping slightly as needed. Repeat with remaining dough, goat cheese mixture, chopped dill, potatoes, and leeks and more oil and salt to make 3 more galettes. Brush top of dough with egg.
- Bake galettes until crusts are golden brown and potatoes are soft, 30–40 minutes. Drizzle with honey and top with dill sprigs. Sprinkle with pink peppercorns, if using; season with salt and black pepper.
