Caramelized Onion Mushroom Gruyere Tartlets Recipes

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.

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.
