Ingredients
- 1 sheet puff pastry, thawed
- 2 large beefsteak tomatoes, sliced
- 2 large onions, thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon butter
- 1 teaspoon sugar
- 1 tablespoon fresh thyme leaves
- Salt and pepper to taste
- 1 cup shredded mozzarella cheese
- 1/4 cup grated Parmesan cheese
- 1 egg, beaten (for egg wash)
Step-by-Step Instructions
1. Caramelize the Onions
Heat the olive oil and butter in a large skillet over medium heat. Add the sliced onions and cook, stirring occasionally, until they begin to soften. Sprinkle with sugar and continue cooking until the onions are golden brown and caramelized, about 20-25 minutes. Stir in the fresh thyme leaves and season with salt and pepper. Set aside to cool.
2. Prepare the Puff Pastry
Preheat your oven to 375°F (190°C). Roll out the thawed puff pastry on a lightly floured surface to fit your tart pan. Transfer the pastry to the pan and trim any excess edges. Prick the bottom of the pastry with a fork to prevent it from puffing up during baking.
3. Assemble the Tart
Spread the caramelized onions evenly over the puff pastry. Arrange the sliced beefsteak tomatoes on top of the onions, slightly overlapping them. Sprinkle the shredded mozzarella and grated Parmesan cheese over the tomatoes.
4. Bake the Tart
Brush the edges of the puff pastry with the beaten egg wash. Bake in the preheated oven for 25-30 minutes, or until the pastry is golden brown and the cheese is melted and bubbly.
5. Serve
Allow the tart to cool for a few minutes before slicing and serving. Garnish with additional fresh thyme leaves if desired.
Expert Tips
- Choose Ripe Tomatoes: For the best flavor, use ripe beefsteak tomatoes. They should be firm but slightly soft to the touch.
- Evenly Slice the Tomatoes: Use a sharp knife to slice the tomatoes evenly. This ensures they cook uniformly and look beautiful on the tart.
- Prevent a Soggy Crust: To avoid a soggy crust, you can blind bake the puff pastry for 10 minutes before adding the toppings.
- Experiment with Cheeses: Feel free to experiment with different cheeses. Gruyère or goat cheese can add a unique flavor to the tart.
- Add a Touch of Sweetness: A drizzle of balsamic glaze before serving can enhance the sweetness of the caramelized onions and tomatoes.
