Potato Asiago Caramelized Onion Galette Recipes

POTATO ONION GALETTE

Steps:

• Make the pate brisee and roll into a cylinder. Chill for 1/2 hour or up to 3 days.
• Heat the butter and 1 tablespoon of the oil in a large skillet. Season with salt, pepper and thyme and cook the onions over medium low heat until caramelized. Remove the onions from skillet and set aside in a bowl to cool. Heat the remaining tablespoon of oil in the skillet and saute the potatoes, seasoned with salt and pepper, until about 3/4 cooked. Combine the potatoes with the onions, mix in 1/4 cup Parmesan and set aside to cool completely. Preheat oven to 400 degrees.
• Cut the cylinder of dough in half and refrigerate one half. Press the piece of dough into a rectangle and then roll it, on a lightly floured surface, into a rectangle measuring about 17 x 8 inches. Brush off any excess flour and transfer the dough to an ungreased cookie sheet. Position it so that there is room for the second piece. Refrigerate the tray while you roll out the second piece of dough in the same way and place it on the cookie sheet.
• Using a serrated pastry wheel, trim the edges of the rectangles to even them. Cut a "v" out of each corner to prevent the dough from bunching when it's folded. Spread half the potato/onion mixture on each, leaving a 1 1/2-inch border all around. Fold up the edges. Brush the dough with egg wash and sprinkle the remaining Parmesan over the dough and filling. Bake about 40 minutes, or until the crust is nicely browned. Slice each section on the diagonal into about 6 pieces.

CARAMELIZED ONION GALETTE

Steps:

• Prepare the dough: In a large bowl, whisk together flour, sugar, 1 1/2 teaspoons kosher salt and 1 1/2 teaspoons black pepper. Add butter and 1 cup grated Gruyère to the flour mixture and toss to coat. Using your fingertips, pinch the butter and cheese into the flour to make pebble-size pieces. Drizzle in the ice water and stir to make a shaggy dough. Dump the dough onto a large sheet of plastic wrap and knead a few times to combine. Wrap in plastic and refrigerate for at least 4 hours.
• Prepare the onions: In a large skillet, melt the butter over medium-high heat. Add onions and thyme sprigs, season with 1 teaspoon salt and 1/2 teaspoon pepper and cook, stirring occasionally, until the onions are translucent and lightly golden on the edges, 20 to 25 minutes. Reduce the heat to medium, add broth and sherry and cook until the onions are browned and the liquid has mostly evaporated but the mixture is still saucy, 16 to 18 minutes. Transfer to a bowl and set aside to cool for at least 30 minutes.
• Heat the oven to 375 degrees. Roll the dough into a 13-inch round on a sheet of parchment. Spread the cooled caramelized onions on the dough, leaving a 1- to 2-inch border. Fold the edges in, over the onions, transfer to a baking sheet and bake until the dough is golden brown and some of the onions have browned on the edges, 40 to 50 minutes, rotating the galette halfway into the baking process.
• Remove galette from the oven and sprinkle remaining 1/3 cup grated Gruyère on the crust. Bake another 5 minutes to melt the cheese. Remove and let rest for 10 minutes before slicing. Top with remaining thyme leaves, for garnish.
