Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper. Roll out the thawed puff pastry sheet on a lightly floured surface into a 12-inch circle, then transfer to the baking sheet.
  2. Step 2: Brush the pastry edge with 1 tsp beaten egg. Prick the center with a fork, then bake for 12 minutes until golden and puffed.
  3. Step 3: While the pastry bakes, heat 2 tbsp olive oil in a skillet over medium-high heat. Add 1/4 sliced yellow onion, 1/2 sliced red bell pepper, and 1 medium sliced zucchini. Sauté for 8-10 minutes until vegetables are tender and lightly caramelized.
  4. Step 4: Stir in 1 tbsp fresh thyme, 1 tsp fresh rosemary, 1/4 tsp salt, and 1/8 tsp black pepper. Remove from heat and let cool slightly.
  5. Step 5: Spread the roasted vegetable mixture evenly over the baked pastry base. Mix 1/2 cup shredded Gruyère cheese with 1 tsp Dijon mustard and 1 tsp beaten egg, then sprinkle evenly over vegetables.
  6. Step 6: Bake for 15-18 minutes until the cheese is melted and bubbly and the pastry edges are deep golden brown.
