Potato Onion Sage And Gruyère Tart Recipes

POTATO, ONION, SAGE AND GRUYèRE TART

Steps:

• Preheat the oven to 190C/170C Fan/Gas 5.
• Put the olive oil and sage leaves in a pan. Fry until crisp and then immediately remove the sage leaves and set aside.
• Add the sliced onions to the same pan. Cook over a low to moderate heat for 20-30 minutes, stirring occasionally, until soft and caramelised. Set aside.
• Lay the puff pastry out on a lined baking tray and top with the caramelised onions, leaving a border all around. Top with the potatoes and grated gruyère. Bake for 20-25 minutes.
• Remove from the oven when golden-brown, garnish with the crisp sage leaves and serve.

ONION AND SAGE TARTS

Steps:

• 1. Caramelizing the onions. Peel the onions and cut them in half from root to tip. Cut out the dense core at the root end and slice the onions 1/4 inch thick, again from root end to tip. Cook the bacon, stirring often, in a large (4-quart) saucepan over medium heat until almost crisp. Add the onions, sugar, and salt, and cook, stirring often until they cook down by two-thirds, about 10 minutes. Add 2 teaspoons vinegar, reduce the heat to medium-low, and continue to cook until the onions are an even golden brown and softened to a marmalade consistency, 15 to 30 minutes, depending on the onions. Stir often and scrape up any brown bits clinging to the bottom of the pan. The onions need almost constant stirring near the end to prevent them from sticking and burning. They'll let you know they need attention by giving off a sizzling sound. Stir in the sage, allow them to cool slightly, then taste and season with black pepper and additional salt if needed. If the onions seem overly sweet, stir in another teaspoon of vinegar. (The onions can be caramelized up to 2 days ahead and store covered in the refrigerator.)
• 2. Filling and baking. Preheat the oven to 350°F. Stir the cream and egg into the caramelized onions until thoroughly combined. Divide the filling among the tart shells and spread it evenly with the back of a spoon. Bake in the upper third of the oven until the filling is set, about 15 minutes. The filling should still be soft but not runny. Let cool slightly, then transfer the tarts to a cutting board using a large spatula. Cut each into 8 wedges with the downward pressure of a sharp chef's knife. Serve warm or at room temperature.
• Variations
• For large tarts, prebake 2 10-inch Free-Form Tart Shells. Divide the onion mixture between them and bake the tarts until the filling is set in the center, 20 to 25 minutes. Using a large spatula, transfer them to a cutting board and cut each into 12 wedges.
• Herb Substitutions
• In place of sage, use an equal amount of finely chopped rosemary, marjoram, savory, English thyme, or lemon thyme.

CARAMELIZED ONION POTATO TART

Steps:

• Preheat oven to 350 degrees F.
• Set a large skillet over medium heat and add 4 tablespoons of olive oil. Add sliced onions and cook over medium heat for 10 to 12 minutes until they are tender and brown all over.
• Using a mandolin (or sharp knife), finely slice the potatoes into rounds (you can place them in a bowl with a wet towel over the top to stop them from going brown while you work). Place the potatoes into a bowl and season with salt and pepper. When ready, add the onions and toss to combine without breaking potatoes.
• Add about 1 tablespoon water to the same pan the onions were cooked in and allow it to come to a bubble. Using layered paper towels, wipe the pan clean.
• Add some extra-virgin olive oil to the pan and add the potatoes to the pan, making sure the potatoes are flat. Top with the diced butter.
• Take a piece of parchment paper and fold in half. Find the middle of the parchment along the crease and hold in place with your finger. Taking the right side of the parchment, pull it towards the center and fold it straight down to create a diagonal edge. Fold the parchment in half to create a triangle. Place the pointed edge in the middle of the saute pan on top of the potatoes to find its radius. Make a marker of where the pan edge ends (or starts). At this point you can cut the parchment at this marker and open to reveal a circle.
• Cover the potatoes with the parchment paper and press down. Drizzle some extra-virgin olive oil over the top so it down burn and rub it in.
• Place the pan into the oven on the top rack and bake for about 45 minutes.
• When done remove from oven and run a knife around the edge to separate from the pan. Place a large plate on top of the saute pan and flip. Remove the saute pan. Allow to cool slightly before cutting into slices.
