Ingredients
- 1 sheet puff pastry, thawed
- 2 large beefsteak tomatoes, sliced
- 2 large onions, thinly sliced
- 2 tbsp olive oil
- 1 tbsp butter
- 1 tbsp fresh thyme leaves
- 1 tsp sugar
- Salt and pepper to taste
- 1 cup grated Gruyère cheese (optional)
- 1 tbsp Dijon mustard (optional)
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 are soft and golden brown, about 20-25 minutes. Sprinkle with sugar, thyme, salt, and pepper. Remove from heat and let cool.
2. Prepare the Puff Pastry
Preheat your oven to 375°F (190°C). Roll out the puff pastry on a lightly floured surface and transfer it to a baking sheet lined with parchment paper. If using, spread a thin layer of Dijon mustard over the pastry, leaving a 1-inch border.
3. Assemble the Tart
Spread the caramelized onions evenly over the puff pastry. Arrange the tomato slices on top of the onions, overlapping slightly. Sprinkle with grated Gruyère cheese if desired. Fold the edges of the pastry inward to create a rustic border.
4. Bake the Tart
Bake in the preheated oven for 25-30 minutes, or until the pastry is golden brown and the tomatoes are tender. Let the tart cool slightly before slicing and serving.
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.
- Prevent Soggy Pastry: To avoid a soggy crust, pat the tomato slices dry with a paper towel before arranging them on the tart.
- Add Extra Flavor: For an added depth of flavor, sprinkle the tart with fresh basil or a drizzle of balsamic glaze before serving.
- 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. The key is to use tomatoes that are meaty and flavorful.
Can I make this tart without cheese?
Absolutely! The tart is delicious with or without cheese. If you prefer a dairy-free option, simply omit the Gruyère cheese.
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.
