Caramelized Onion and Apple Tarts with Gruyère and Thyme
January 31, 2015
Here is a sophisticated hors d'oeuvre of Caramelized Onion and Apple Tarts with Gruyere and Thyme. Every party needs an easy and elegant appetizer to keep guests satisfied until the main event. This recipe from the Williams Sonoma website is just the thing: simple, pretty and delicious.
- Prep: 10 mins
- Cook: 1 hrs 5 mins
- Yields: Makes 32 tarts
Ingredients
1 1/2 pound yellow onions, halved and thinly sliced
1 teaspoon kosher salt, plus more, to taste
1 pound tart apples, peeled and sliced 1/8 inch thick
1 1/2 oz aged Gruyère cheese, coarsely grated
2 Tablespoons fresh chives, minced
1 teaspoon chopped fresh thyme
1/8 teaspoon freshly ground pepper, plus more, to taste
Directions
1In a large fry pan over medium heat, warm the oil. Add the onions and the 1 tsp salt and cook, stirring occasionally, until the onions are golden brown, about 30 minutes. Transfer to a large bowl and let the filling cool to room temperature.
2Position 1 rack in the upper third and 1 rack in the lower third of an oven and preheat to 400°F. Line 2 baking sheets with parchment paper.
3In the same pan over medium heat, melt the butter. Add the apples and sugar and stir to coat the apples. Cook, stirring, until the apples are just starting to caramelize and have softened, about 10 minutes. Transfer to the bowl with the onions and stir in the cheese, chives, thyme and the 1/8 tsp. pepper.
4Cut the puff pastry into 2-inch squares and place on the prepared baking sheets, spacing the squares about 1 inch apart. Brush the pastry squares with the egg mixture and place a heaping 1 Tbs filling in the center of each square. Season with salt and pepper.
5Bake, rotating the baking sheets from top to bottom and front to back halfway through baking, until the pastry is crisp underneath and golden brown on top, about 25 minutes. Transfer the baking sheets to wire racks and let the tarts cool to room temperature. Serve at room temperature.
