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.

FRENCH ONION TART

Steps:

• Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper.
• On a work surface, roll the puff pastry into a roughly 10 by 16-inch rectangle. With a sharp knife, trim uneven edges to make a perfect rectangle. Evenly cut off the outer 1 inch of each side of the rectangle in strips; put the puff sheet on the baking sheet. Dip your finger in water and run around the top edges of the rectangle and replace the removed strips of pastry along the edges of the sheet, pressing lightly to adhere. With a fork, pierce the interior of the tart shell to prevent rising; do not pierce the adhered edges. Bake until the outer edges have puffed and are golden in color; about 15 minutes. Set aside.
• Heat 2 tablespoons olive oil in a large skillet over medium-low heat. Add onions and thyme sprigs and season well with salt and pepper, to taste. Cook, stirring occasionally, until the onions begin to brown. Add the stock, a tablespoon at a time, as the pan gets dry, scraping and stirring the brown bits that are stuck to the bottom oft the pan. When the onions are caramelized to a dark golden color, remove from the heat and discard the leafless thyme sprigs (the leaves fall off while cooking).
• When ready to serve, preheat the oven to 350 degrees F. Evenly spread the caramelized onions on the cooked pastry shell and heat in the oven until warmed through, 5 to 7 minutes. Remove from oven, to a cutting board and cut into wedges. Arrange on a serving platter and garnish each wedge with a sprig of fresh thyme. Serve immediately and enjoy!

THE ULTIMATE MAKEOVER: ONION TART

Steps:

• Slice the onions into small, thin, wedge-shaped pieces. Heat the rapeseed oil in a large, preferably non-stick, sauté or deep frying pan. Stir in the onions and fry over a medium heat for about 20 mins. Stir only occasionally so they can cook fairly undisturbed and caramelise underneath. When done, they should be well caramelised and sticky.
• Meanwhile, prepare the base. Heat oven to 190C/170C fan/gas 5 and put in a baking sheet. Put the flour and butter in a bowl with a pinch of salt and rub with your fingers until it resembles rough crumbs. Mix the yogurt and milk, pour it into the flour mixture and work together briefly with a knife until the dough just comes together. Remove from the bowl and gently press together to form a ball. Do not overwork the mixture.
• Roll dough out thinly on a lightly floured surface and use to line a 23cm round, fluted, loose-based flan tin, about 2.5cm depth, pressing it with your fingers into the flutes. Sit the tin on. If the dough is a little sticky, dust your fingers in some flour.
• Beat the eggs in a medium bowl, then stir in the crème fraîche, thyme, mustard and seasoning. Spoon and spread half of the onions into the lined base, season with pepper then scatter over half the cheese. Pour the egg mixture over the top, then scatter over the rest of the onions and cheese. Sit the tin on the hot baking sheet and bake for 25-30 mins until the base and filling are cooked. Remove and cool for about 10 mins, then remove from the tin and serve while fresh and warm.
