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
- 1 tbsp Dijon mustard
Step-by-Step Instructions
1. Caramelize the Onions
Heat olive oil and butter in a pan over medium heat. Add the sliced onions and cook until soft and translucent. Sprinkle with sugar and continue cooking until the onions are golden brown and caramelized. Stir in the thyme leaves and season with salt and pepper. Set aside to cool.
2. Prepare the Puff Pastry
Roll out the thawed puff pastry on a lightly floured surface. Transfer it to a baking sheet lined with parchment paper. Spread a thin layer of Dijon mustard over the pastry, leaving a small border around the edges.
3. Assemble the Tart
Sprinkle the grated Gruyère cheese evenly over the mustard layer. Arrange the caramelized onions on top of the cheese, followed by the sliced beefsteak tomatoes. Season the tomatoes with salt and pepper.
4. Bake the Tart
Preheat the oven to 375°F (190°C). Bake the tart for 25-30 minutes, or until the pastry is golden brown and the cheese is bubbly and melted.
5. Serve
Allow the tart to cool slightly before slicing. Garnish with additional fresh thyme leaves if desired. Serve warm and enjoy!
Expert Tips
- Choose Ripe Tomatoes: For the best flavor, use ripe 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.
- Experiment with Cheese: While Gruyère adds a rich, nutty flavor, you can also try using Parmesan or sharp cheddar for a different taste.
