Best 3 Spinach And Onion Tart Recipes

SPINACH AND ONION TART

Steps:

• Preheat the oven to 350 degrees. Oil a 10-inch tart pan and line it with the pastry. Keep it in the refrigerator while you prepare the filling.
• Steam the spinach above an inch of boiling water for 2 to 3 minutes, until wilted. You will probably have to do this in batches. I like to use a pasta pot with an insert for steaming spinach, as I can get a lot of it into the insert. Rinse briefly with cold water, squeeze out excess water and chop medium-fine.
• Heat the olive oil over medium heat in a large, heavy skillet and add the onion. Cook, stirring often, until it is tender and beginning to color, about 8 minutes. Add the spinach, thyme and salt and pepper to taste, and stir together. Remove from the heat.
• Whisk the eggs in a large bowl. Add salt to taste (I use about 1/2 teaspoon) and whisk in the milk. Stir in the onion and spinach mixture and the cheeses. Scrape into the pastry-lined tart pan. Place in the oven and bake 40 to 45 minutes, until tart is set and beginning to color on the top. Remove from the heat and allow to cool for at least 15 minutes before cutting. Serve warm or room temperature.

ONION, BACON AND SPINACH TART

Steps:

• 1. Heat oven to 375 degrees F. Fit piecrust into 9-inch tart pan. Trim excess crust from top edge of tart pan; refrigerate while preparing filling. 2. Heat a large nonstick skillet over medium heat. Add bacon to skillet and cook, stirring often, for 8 minutes. Add spinach to skillet and cook 1 minute, stirring until wilted. Using a slotted spoon, remove bacon mixture to a paper-towel-lined plate. 3. Return skillet to medium heat and add onions, 1/4 teaspoon salt and the thyme. Cover and cook 25 minutes over medium heat, stirring occasionally, or until browned. Remove from heat and allow to cool, uncovered, 5 minutes. 4. Whisk together eggs, half-and-half, pepper and the remaining 1/2 teaspoon salt. Stir bacon mixture and onions into eggs; stir to combine. Pour egg mixture into crust. Bake at 375 degrees F for 15 minutes. Reduce heat to 325 degrees F and continue to bake 20 minutes. 5. Heat broiler. Sprinkle tart with Gruyere and broil for 1 to 2 minutes. Let stand 5 minutes before slicing and serving.

SPINACH AND ONION TART

Steps:

• In a heavy, deep saucepan, melt butter over medium-low heat. Add onions. Cook, stirring frequently, until onions are soft and translucent, about 15 minutes. Remove and discard the tough center ribs from the sorrel leaves. Bring a large stockpot of water to a boil, and add 2 teaspoons salt. Add sorrel, and cook just until the leaves wilt, 1 to 2 minutes. Drain sorrel in a colander, let cool, and squeeze out any excess liquid. Add sorrel, the remaining teaspoon salt, and the pepper to the onions; cook over low heat until mixture breaks down and is almost soupy, about 20 minutes. Remove from heat, and let cool. Preheat oven to 400 degrees. Line two baking sheets with parchment. On a lightly floured surface, roll one sheet of puff pastry into a 7-by-11-inch rectangle, about 1/8 inch thick. Transfer the dough to one of the parchment-lined baking sheets, and chill in refrigerator 30 minutes. Repeat process with the second sheet of puff pastry. Remove both sheets of puff pastry from the refrigerator. Using a sharp knife, score a 1/2-inch border around perimeter of each sheet, creating a picture-frame look. Using a fork, prick the entire surface within the scored edges on each sheet. Make an egg glaze: In a small bowl, combine 1 egg yolk and 2 tablespoons heavy cream; carefully brush egg glaze onto the borders. Transfer both sheets of dough to oven, and bake until pastry has puffed up and is golden brown, about 15 minutes. Remove pastry from oven, and transfer to a wire rack to cool. Add the remaining egg yolk and remaining 2 tablespoons cream to the sorrel mixture, and stir to combine. Divide the filling in two, and spread one half over each puff pastry. Return the tarts to the oven, and bake until the filling is hot throughout, about 20 minutes. Remove the tarts from the oven, and transfer to a wire rack to cool, about 10 minutes. Cut tarts into 2-inch squares, and serve warm.
