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
- 2 sprigs fresh thyme, leaves stripped
- Salt and pepper to taste
- 1 cup ricotta 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 thinly sliced onions and cook, stirring occasionally, until they begin to soften. Sprinkle with sugar and continue cooking, stirring frequently, until the onions are golden brown and caramelized. This process should take about 20-25 minutes. Stir in the 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 or baking sheet. Transfer the pastry to the pan and trim any excess edges. Prick the base of the pastry with a fork to prevent it from puffing up too much during baking.
3. Assemble the Tart
Spread a layer of ricotta cheese evenly over the puff pastry base. Top with the caramelized onions, spreading them out in an even layer. Arrange the beefsteak tomato slices on top of the onions, slightly overlapping them. Season the tomatoes with salt and pepper.
4. Bake the Tart
Brush the edges of the puff pastry with the beaten egg to create a golden, glossy finish. Bake in the preheated oven for 25-30 minutes, or until the pastry is golden brown and the tomatoes are slightly roasted.
5. Serve and Enjoy
Allow the tart to cool for a few minutes before slicing and serving. Garnish with additional fresh thyme leaves if desired. This tart pairs beautifully with a simple green salad or a refreshing Peach Heirloom Tomato Salad.
Expert Tips
- Choose Ripe Tomatoes: For the best flavor, use ripe, in-season beefsteak tomatoes. They should be firm but slightly yielding to the touch.
- Even Slicing: Slice the tomatoes evenly to ensure they cook uniformly and look beautiful on the tart.
- Prevent Soggy Pastry: To avoid a soggy crust, pat the tomato slices dry with a paper towel before placing them on the tart.
- Add Cheese: For an extra layer of flavor, sprinkle grated Parmesan or crumbled feta cheese over the tomatoes before baking.
- Make Ahead: You can prepare the caramelized onions a day ahead and store them in the refrigerator. Assemble and bake the tart just before serving.
FAQ
Can I use a different type of tomato?
Yes, you can substitute beefsteak tomatoes with heirloom tomatoes or large vine-ripened tomatoes. However, beefsteak tomatoes are ideal due to their meaty texture and rich flavor.
How do I store leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheat in the oven at 350°F (175°C) for about 10 minutes to restore the crispiness of the pastry.
Can I freeze this tart?
While it’s best enjoyed fresh, you can freeze the tart before baking. Assemble the tart, wrap it tightly in plastic wrap and aluminum foil, and freeze for up to 1 month. Bake directly from frozen, adding a few extra minutes to the baking time.
