Best 5 Upside Down Potato Onion Tart Recipes

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.

POTATO, ONION, CHEDDAR UPSIDE DOWN PIE

Steps:

• 1. The number of potatoes will depend on their size. I used red potatoes, but Yukon gold or russet would work fine too. Slice potatoes and onion very thin by hand or using your mandolin.
• 2. I used a cast iron skillet. I drizzled about 2 tbs. of olive oil in the bottom and brushed it around to cover well. Then I sprinkled black pepper and Mrs. Dash original blend in the bottom of the pan to suit my taste. Next layer slices of onion in the bottom.
• 3. Then I added a generous layer of potatoes, re-seasoned with Mrs. Dash.
• 4. Then a generous layer of cheddar.
• 5. Then another layer of potatoes with Mrs. Dash and a little drizzle of olive oil. Place an oven proof lid on and bake at 375° for 30 min., remove lid and bake another 20 min. or until fork slides in easily.
• 6. Let stand for about 10 min. then loosen sides with a spatula, and run it under potatoes to make sure they are not stuck to bottom. Then invert onto plate.
• 7. Next I decided to make a topping for them. I had planned to do a juicy roasted tomato and Thai chili sauce, but ended up adding sour cream and cilantro too.
• 8. First I cut enough cherry tomatoes in half to fill up my small non stick skillet, about 1/2 pint. I drizzled with olive oil and let them cook for about 20 min.
• 9. Once they were somewhat caramelized on the bottom I added 4 oz. of sour cream, 1 tbs. Thai chili sauce and 1/2 c. chopped fresh cilantro. Then I poured it onto the potatoes and spread it out. Super delicious!!!!

UPSIDE DOWN POTATO & ONION TART

• Place the potato, oil, cheeses, salt and pepper in a bowl and toss to combine.

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!
