Caramelized Onion Tart Recipe

Introduction:

A caramelized onion tart is a savory delight that combines the sweet, rich flavor of caramelized onions with a buttery pastry crust. This dish is perfect as an elegant appetizer, a light main course, or a sophisticated addition to any brunch or dinner party. The slow cooking of the onions brings out their natural sweetness, complementing the crisp, golden crust.

Ingredients:

• For the pastry:
  • 1 1/4 cups all-purpose flour
  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter, chilled and diced
  • 3-4 tablespoons ice water
• For the filling:
  • 3 tablespoons olive oil
  • 4 large onions, thinly sliced
  • 1 teaspoon sugar
  • 1 teaspoon balsamic vinegar
  • Salt and pepper to taste
  • 2 tablespoons fresh thyme leaves
  • 3/4 cup grated Gruyère cheese

Instructions:

1. Prepare the pastry: In a mixing bowl, combine flour and salt. Add butter and use a pastry cutter to blend until the mixture resembles coarse crumbs. Gradually add ice water, stirring until the mixture forms a dough. Wrap in plastic and refrigerate for at least 30 minutes.
2. Caramelize the onions: Heat olive oil in a large skillet over medium heat. Add onions and cook, stirring occasionally, for about 20 minutes until they are golden brown. Add sugar and balsamic vinegar, and cook for another 5 minutes. Season with salt, pepper, and thyme. Set aside to cool.
3. Assemble the tart: Preheat your oven to 375°F (190°C). On a floured surface, roll out the dough to fit a 9-inch tart pan. Transfer the dough to the pan and press it into the edges. Trim any excess dough. Spread the caramelized onions evenly over the crust. Sprinkle with grated Gruyère cheese.
4. Bake the tart: Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden brown.
5. Cool and serve: Let the tart cool for a few minutes before removing from the pan. Cut into slices and serve warm.

Conclusion: This caramelized onion tart offers a harmonious blend of sweet onions and nutty Gruyère cheese, all encased in a flaky, buttery crust. It’s a versatile recipe that can be served in any season and is guaranteed to impress your guests with its depth of flavor and elegant presentation.
