CARAMELIZED ONION AND MUSHROOM TARTLETS

Steps:

• Heat oven to 375°F. Unroll dough on work surface (if using crescent rolls, pinch seams to seal); cut into 24 (2-inch) squares. Press 1 square in bottom and up side of each of 24 ungreased mini muffin cups.
• In 10-inch skillet, heat oil over medium heat. Add onion and thyme; cook 8 to 10 minutes, stirring frequently. Reduce heat to medium-low; cook 6 to 9 minutes, stirring constantly, until onions are caramelized. Stir in brown sugar and wine; cook 2 to 3 minutes, stirring constantly, until liquid is gone. Stir in mushrooms. Spoon about 1 tablespoon onion-mushroom mixture into each cup. Top with walnuts and cheese.
• Bake 12 to 15 minutes or until golden brown. Remove tartlets from pan immediately. Serve warm.

CARAMELIZED ONION, MUSHROOM & GRUYERE TARTLETS

Steps:

• Preheat oven to 400 degrees F and line two baking sheets with parchment paper.
• Heat the olive oil in a wide, heavy-bottomed pan over medium-low heat and add the onions. Cook, stirring occasionally, until they begin to caramelize, about 20 minutes.
• Add the butter to the pan. Once melted, add the mushrooms and saute, stirring occasionally, until they are completely soft and all of the liquid evaporates, about 20 minutes.
• Add the garlic and the thyme and saute until fragrant, about 1 minute. Season with salt and pepper to taste.
• Add the wine, scraping the bottom of the pan to pull up all of the browned bits, and cook until all of the liquid has evaporated. Remove from heat.
• Unfold the thawed sheets of puff pastry and cut out circles from the dough, placing them evenly spaced on the baking sheets. Using a very sharp knife, make four small scores around the perimeter of the dough, about ¼ to ½-inch from the edge.
• Top the rounds of puff pastry with a small spoonful of the onion and mushroom mixture, trying to keep the filling within the score marks. Top with the shredded Gruyere cheese. Brush the edges of the dough rounds with the egg wash.
• Bake until the pastry is golden brown, about 15 to 25 minutes. Garnish with fresh chopped parsley.

EASY TART WITH CARAMELIZED ONIONS, MUSHROOMS AND GRUYèRE

Steps:

• Heat a large saucepan over medium-high heat. When the pan is hot, add the olive oil and the butter together, followed by the sliced onions. Cook for about 10 minutes or until the onions wilt and start to brown. At that point add the next three ingredients (sugar, vinegar, salt and pepper). Reduce the heat and cook gently, uncovered for about 20 more minutes or until the onions are completely caramelized. Add a little water if the onions look like they are drying out. Taste and adjust the seasoning. Remove the onions to a separate bowl.
• Add the sliced mushrooms to the same pot and sauté (without oil) for a few minutes until they release their moisture. At that point, add a little olive oil and the thyme leaves and cook for a few minutes, stirring frequently. Once the mushrooms start lightly brown, add the sliced potatoes and the fennel seeds. Season everything with some salt and pepper and cook for a few more minutes, until the potatoes soften a little. Set the mixture aside to cool.
• Unfold the thawed sheet of puff pastry and place it on a work surface. Roll it out into a 10"x14" rectangle and remove it to a baking sheet lined with parchment paper. Prick with a fork every few inches to prevent the pastry from bubbling while it bakes. Using a very sharp knife, score the perimeter of the dough about ¼- to ½-inch from the edge.
• Spread the cooled onions evenly over the puff pastry. Top with the sautéed mushrooms and potatoes and sprinkle with the Gruyère cheese. (Refrigerate if not baking immediately).
• Preheat the oven to 375°F. Bake the puff pastry on the middle rack for 25-30 minutes or until the cheese is bubbling and crust is nice and golden. Allow the tart to cool for 10 minutes then cut it into 20 little rectangles. Serve warm or at room temperature.

CARAMELISED MUSHROOM TARTLETS

Steps:

• Heat the oil in a generous frying pan, add the onion and fry over moderate heat for about 7 mins until soft and golden. Stir in the sugar and seasoning, turn up the heat and add the mushrooms. Sizzle for 5 mins until you have driven off any moisture and the mushrooms are golden. Stir in the garlic for a few further mins, until fragrant, then turn off the heat and stir in most of the thyme (save some for sprinkling). The mushroom mix can be chilled at this point.
• To make the tartlet bases, cut 7-8cm circles out of the bread using a cookie cutter or glass. Butter one side and stick buttered-side down into a 12-hole tartlet tin. Freeze any leftovers to make breadcrumbs.
• When ready to bake, heat oven to 220C/200 fan/gas 7. Divide the mushroom mixture between the tartlets and top with a sprinkle of cheese. Don't be too tidy about this - any cheese on the tin will form a lacy edge to the tartlets. Bake for 10-15 mins until golden and bubbling. Sprinkle over the reserved herbs and serve.

CARAMELIZED ONION, MUSHROOM AND GRUYERE QUICHE WITH OAT CRUST

Steps:

• Preheat the oven to 400 degrees F. Spray a 9-inch pie dish with cooking spray.
• To prepare the crust, put the oats, flour and salt in the bowl of a food processor and pulse 3 times to combine. Add the butter and pulse about 12 times, until you get a pebbly course texture. Add the buttermilk and pulse 3 to 5 times more to combine. Form the mixture into a ball and place it between 2 large pieces of waxed paper. Roll out into a circle about 10 inches in diameter.
• Remove the top sheet of waxed paper. Transfer the crust, still on the other piece of waxed paper to the pie dish, then remove the waxed paper from the top. Press the crust gently into the dish. Bake for 9 minutes, then let cool.
• To prepare the filling, heat 2 teaspoons of oil in a large nonstick pan over a medium-low heat. Add the onion and cook, stirring occasionally, until golden brown and caramelized, about 20 minutes. Transfer the onions to a bowl. Add the remaining 2 teaspoons of oil to the pan and heat over a medium-high heat. Add the mushrooms and cook, stirring occasionally, until they have released their water and begin to brown, about 6 minutes. Add the onions back to the pan, stir in the salt, pepper, mustard and thyme.
• In a medium bowl whisk together the eggs, egg whites and evaporated milk.
• Sprinkle the cheese into the pie crust. Top with the mushroom-onion mixture and pour the egg mixture on top. Reduce oven temperature to 350 degrees F. Bake for 35 minutes or until knife inserted in the middle comes out clean. Let stand for 5 minutes before cutting into 6 wedges and serving.
