Ingredients

• 1 sheet puff pastry
• 3 tablespoons Dijon mustard
• 3 medium ripe tomatoes
• 1 cup grated Gruyère cheese
• 1 tablespoon olive oil
• 1 teaspoon dried herbes de Provence
• 5 leaves fresh basil leaves
• 0.5 teaspoon salt
• 0.5 teaspoon black pepper

Directions

Step 1

Preheat your oven to 400°F (200°C).

Step 2

Roll out the puff pastry sheet on a lightly floured surface to fit a 9-inch tart pan or baking sheet. Gently press it into the pan and trim any excess edges.

Step 3

Prick the bottom of the puff pastry with a fork to prevent it from puffing up excessively during baking.

Step 4

Spread the Dijon mustard evenly across the base of the pastry.

Step 5

Slice the tomatoes thinly and arrange them in overlapping layers over the mustard-covered base.

Step 6

Sprinkle the grated Gruyère cheese evenly over the tomatoes.

Step 7

Drizzle olive oil over the top and sprinkle with herbes de Provence, salt, and black pepper.

Step 8

Bake in the preheated oven for 25–30 minutes, or until the pastry is golden brown and crisp.

Step 9

Remove the pie from the oven and let it cool for 5 minutes.

Step 10

Garnish with fresh basil leaves before serving. Serve warm or at room temperature.
