Savory Caramelized Onion and Two-Tomato Tart
This tart has a pleasant sweetness to it,
thanks to the caramelized onions and the fresh summer tomatoes.
Makes one tart (9 servings)
1 tablespoon unsalted butter
1 medium onion, halved and thinly sliced
2 garlic cloves, smashed
2 thyme sprigs, stems removed and discarded
¾ teaspoon kosher salt, divided
1 cup mixed red and yellow grape tomatoes, halved
1 sheet prepared puff pastry, defrosted
egg wash (1 large egg and 1 teaspoon water, whisked together)
½ cup plus 1 tablespoon shredded Comté cheese, divided
¼ cup fresh ricotta, strained of any excess water
2 large basil leaves, thinly sliced or torn into small pieces
1. Put the butter, onion, garlic, thyme and ½ teaspoon of the salt into a medium
skillet set over low heat. Cook until the onions are deeply golden, stirring
occasionally – the onion must cook slowly, so if it seems as though it is
browning too quickly or getting too dark, lower the heat. This process will
take about 45 minutes to 1 hour.
2. While the onion is caramelizing, toss the tomatoes in a small bowl with the
remaining salt; reserve.
3. Line the baking pan with parchment paper. Roll out the sheet of pastry on
a well-floured surface; cut to fit pan and place on the prepared pan, folding
over the edges to make a border. Using the tines of a fork, prick the surface
of the tart shell all over, in the center and on the border. Brush the egg wash
all over the tart shell.
4. Preheat oven on Convection Bake at 400°F with the rack in the lower
position. Place the empty tart shell on the rack and bake for 20 minutes.
Keep an eye on the shell to make sure the surface does not get too dark.
Cover with aluminum foil, if it gets dark before time expires.
5. Once shell is baked and cools slightly, press down center of tart shell
slightly to keep edges up. Scatter ¼ cup of the shredded cheese along
the bottom of the tart shell. Put ½-tablespoon dollops of the ricotta on top
of the cheese evenly across the tart; sprinkle with half of the remaining
salt. Top evenly with the onion mixture and then the tomatoes, and finally
the remaining cheese and salt. Place back into the oven in the upper rack
position. Set oven to Broil for about 8 to 10 minutes, until cheese is melted
and golden brown.
6. Scatter the basil on top of the tart before serving.
