Best Tomato Caramelised Onion Tart Tatin Recipes

TOMATO TART TATIN

Steps:

• Set up your grill for indirect heat. If using a charcoal grill, build the coals on one side only. If using a gas grill, heat one side only.
• Season the tomato halves with kosher salt and pepper and set aside. Place the sugar in a large enameled cast iron braiser or saute pan over the direct heat side of the grill. Shake out into an even layer and allow to melt then caramelize, 2 to 3 minutes. Add the vinegar and deglaze the pan, scraping the bottom of the pan for any brown bits. Stir in the garlic, onions and thyme, then the parsley and allow the liquid to melt back down. Remove from the heat.
• Place the tomatoes flesh side down on top of the onions. Place on the indirect heat side of the grill, close the lid and vents of the grill (this will make the temperature drop to 225 to 250 degrees F) and bake until the skins are wrinkly and the tomatoes have softened and given up more liquid, 2 hours.
• Brush another large enameled cast iron braiser or saute pan with the butter. When the tomatoes are ready, scoop the tomatoes out of their juices and place them in the buttered pan, cut side up and skin side down. Add the caramelized onions on top of the tomatoes. Using kitchen shears, cut off the square edges of the puff pastry, rounding the edges. Top the tomatoes and onions with the puff pastry round.
• Place the pan on the indirect heat side of the grill, with the air vents open, and cover the grill. The temperature should be around 425 degrees F. Bake until golden brown and the pastry is puffed, 25 to 30 minutes. Cool in the pan for 3 minutes before turning out on to a plate. Garnish with a sprig of basil in the center and sprinkle with flakey salt.

CARAMELIZED ONION TART

Steps:

• Thaw the pastry sheet at room temperature for 40 minutes or until it's easy to handle. Heat the oven to 400 degrees F. Line a baking sheet with parchment paper or spray with vegetable cooking spray.
• Heat the oil in a 12-inch skillet over medium heat. Add the onion and cook for about 15 minutes or until golden, stirring often. Season to taste and let cool.
• Unfold the pastry sheet on a lightly floured surface. Roll into a 12-inch square. Place on the prepared baking sheet. Brush the edges of the square with water. Fold over the edges 1/2 inch on all sides, pressing firmly with a fork to form a rim. Prick the pastry thoroughly with a fork.
• Spread the onion mixture over the pastry crust. Top with the gruyere and parmesan cheeses and sprinkle with the chives.
• Bake for 20 minutes or until golden and bubbly. Cool for 5 minutes on a wire rack. Cut into approximately 3 x 2-inch rectangles. Serve warm.

Steps:

• Preheat oven to 425 degrees. Unfold puff pastry sheet and cut into a 10-inch round; chill, covered, until ready to use.
• Melt butter in a large skillet over medium heat. Add onions and a pinch of sugar and cook, stirring, until onions are golden and caramelized, 15 to 20 minutes. Add 2 tablespoons water and let cook off, scraping brown bits from bottom of pan. Transfer onions to a bowl.
• In a clean, ovenproof 9-inch skillet, combine 1/4 cup sugar and 3 tablespoons water. Cook over medium heat, swirling pan gently (do not stir) until sugar melts and turns amber, 5 to 10 minutes. Add vinegar and swirl gently.
• Sprinkle olives over caramel. Scatter tomatoes over olives, then sprinkle onions on. Season with thyme leaves, salt and pepper. Top with puff pastry round, tucking edges into pan. Cut several long vents in top of pastry.
• Bake tart until crust is puffed and golden, about 30 minutes. Let stand for 5 minutes, then run a knife around pastry to loosen it from pan, and flip tart out onto a serving platter. Cut into wedges and serve immediately.
