Ingredients

• 1 sheet Puff pastry sheet
• 2 tablespoons Butter
• 1 tablespoon Olive oil
• 2 Large onions
• 2 Garlic cloves
• 1 teaspoon Fresh thyme leaves
• 4 Roma tomatoes
• 1 tablespoon Balsamic vinegar
• 1 cup Grated Parmesan cheese
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1 Egg
• 1 teaspoon Water

Directions

Step 1

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

Step 2

Unroll the puff pastry sheet onto the prepared baking sheet and set aside.

Step 3

In a large skillet, melt the butter with the olive oil over medium heat.

Step 4

Slice the onions thinly and add them to the skillet. Cook for 10-12 minutes, stirring occasionally, until caramelized and golden brown.

Step 5

Mince the garlic and add it to the skillet along with the fresh thyme leaves. Cook for another minute until fragrant.

Step 6

Stir in the balsamic vinegar, salt, and black pepper. Remove the onion mixture from the heat and allow it to cool slightly.

Step 7

Slice the Roma tomatoes into thin rounds. Set them aside.

Step 8

In a small bowl, whisk together the egg and water to create an egg wash.

Step 9

Spread the caramelized onion mixture evenly over the puff pastry, leaving a 1-inch border around the edges.

Step 10

Sprinkle half of the Parmesan cheese over the onions, then layer the tomato slices on top.

Step 11

Sprinkle the tomatoes with the remaining Parmesan cheese and lightly season with a pinch of salt and pepper.

Step 12

Brush the edges of the puff pastry with the egg wash to ensure a golden crust during baking.

Step 13

Bake the tart in the preheated oven for 25-30 minutes, or until the pastry is puffed and golden brown.

Step 14

Allow the tart to cool for 5 minutes before slicing. Serve warm or at room temperature.
