  • 1 teaspoon sugar
  • ½ teaspoon salt
  • ½ cup unsalted butter, cold and cut into cubes
  • ¼ cup ice water

the Filling:

  • 2 medium potatoes, thinly sliced
  • 1 tablespoon olive oil
  • 2 large onions, thinly sliced
  • 1 tablespoon balsamic vinegar
  • 1 teaspoon thyme leaves
  • 1 cup Asiago cheese, grated
  • Salt and pepper to taste

For the Glaze:

  • 1 egg, beaten
  • 1 tablespoon water

Ingredient Highlights

  • Asiago Cheese: Adds a sharp, nutty flavor that complements the sweetness of the onions and the earthiness of the potatoes.
  • Caramelized Onions: The slow-cooked onions bring a sweet, rich depth of flavor to the galette.
  • Flaky Butter Crust: The butter in the dough creates a crispy, golden crust that perfectly encases the filling.
  • Potatoes: Thinly sliced potatoes cook to a tender, creamy texture, enhancing the overall heartiness of the dish.

Step-by-Step Instructions

Make the Galette Dough:

  1. Prepare Dough: In a food processor, pulse together flour, sugar, and salt. Add cold butter and pulse until the mixture resembles coarse crumbs.
  2. Add Water: Slowly add ice water, one tablespoon at a time, pulsing until the dough begins to come together.
  3. Chill Dough: Form the dough into a disk, wrap it in plastic wrap, and refrigerate for 15 minutes.

Prepare the Filling:

  1. Caramelize Onions: Heat olive oil in a large skillet over medium heat. Add onions and cook slowly for about 25 minutes, stirring occasionally until they are soft and golden brown. Add balsamic vinegar and thyme, and cook for another 5 minutes. Remove from heat and set aside.
  2. Prepare Potatoes: In the same skillet, heat a little more olive oil and sauté the sliced potatoes for 5-7 minutes, just until slightly tender. Remove from heat and season with salt and pepper.

Assemble the Galette:

  1. Preheat Oven: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
  2. Roll Out Dough: On a lightly floured surface, roll out the dough into a 12-inch circle. Transfer the dough to the prepared baking sheet.
  3. Add Filling: Layer the sautéed potatoes in the center of the dough, leaving a 2-inch border around the edges. Top with caramelized onions and sprinkle with grated Asiago cheese.
  4. Fold Edges: Gently fold the edges of the dough over the filling, pleating as you go to create a rustic border.

Prepare the Glaze:

  1. Brush with Egg Wash: In a small bowl, whisk together the egg and water. Brush the edges of the dough with the egg wash for a golden finish.

Bake the Galette:

  1. Bake: Place the galette in the oven and bake for 45-50 minutes, or until the crust is golden brown and the filling is bubbling.
  2. Cool: Let the galette cool for 10 minutes before slicing and serving.

Serve:

  1. Slice and Serve: Slice the galette into wedges and serve warm.
