Gruyere Caramelized Onion Tarts Recipes

ONION GRUYERE TART

Steps:

• Cut onions into slices about 1/4 inch thick. Chop coarsely.
• Heat butter and oil in heavy skillet. Add onions and cook, covered, over medium heat about 10 minutes, or until onions are limp and begin to render liquid. Add pinch of sugar.
• Uncover onions and cook over medium-high heat 30 to 45 minutes. Stir frequently with a wooden spoon or spatula to scrape up brownings in pan. The onions should be a deep brown and reduced to a small mass. They must be watched carefully and stirred to prevent scorching and to ensure even browning.
• Transfer onions to a bowl. Add wine to skillet and boil, scraping up pan brownings, until liquid is reduced to a thick glaze. Add glaze to onions, along with salt, nutmeg, cream and egg. Adjust seasoning. (Dish may be prepared to this point a day in advance and refrigerated.)
• Preheat oven to 375 degrees.
• Grate cheese and distribute half of it on bottom of chilled pastry shell in pastry tin. Distribute onion mixture evenly over cheese; top with remaining cheese.
• Bake 40 to 45 minutes. If top browns too much, reduce heat slightly toward the end. Serve as a first course, warm or at room temperature. Tart can be made a few hours ahead, but do not refrigerate.

CARAMELIZED ONION, FIG & GRUYERE TART WITH FRESH THYME

Steps:

• Preheat oven to 400 degrees Fahrenheit.
• Lay thawed puff pastry sheet on a floured surface and roll until approximately 10" wide and 16" long. Carefully transfer puff pastry to a baking sheet. Trim edges if desired for a neater look, and prick the pastry several times with a fork.
• Bake the puff pastry sheet for about 10 minutes until puffed and golden. Remove from oven.
• In a large skillet over medium-low heat, heat the olive oil and butter until melted. Add the onions and saute, stirring occasionally, until soft, golden brown, and caramelized, about 40 minutes. Add thyme, garlic, salt, pepper, and vegetable broth to the onions and continue to cook over medium-low heat for about five minutes, stirring frequently. Remove from heat.
• Carefully spread 1/3 cup fig jam over the puff pastry, leaving a 1/2-inch border around the edges. Evenly spread the onions over the top, then sprinkle with the Gruyere cheese.
• Bake at 400 degrees Fahrenheit for 4 - 5 more minutes or until the cheese melts.
• Garnish with additional thyme leaves and serve immediately. This tart may be made several hours ahead and reheated before serving, but I recommend baking it right before serving, otherwise the pastry gets a tad soggy.
