Instructions

  1. Step 1: Preheat oven to 190°C (375°F). Roll out puff pastry on a floured surface to a 30x20cm rectangle, then transfer to a parchment-lined baking sheet.
  2. Step 2: Thinly slice zucchini, eggplant, and red onion into 3mm rounds; arrange in concentric circles over pastry, leaving a 2cm border.
  3. Step 3: Whisk together 100ml heavy cream, 10g chopped thyme, 3g sea salt, and 2g black pepper, then drizzle evenly over vegetables.
  4. Step 4: Sprinkle 50g grated Gruyère cheese over the top, then dot with 15g butter.
  5. Step 5: Fold pastry edges over the vegetable layers to create a neat, high border, then brush with beaten egg (1 egg, beaten with 1 tbsp water).
  6. Step 6: Bake for 35-40 minutes until crust is golden brown and vegetables are tender when pierced with a fork.
  7. Step 7: Let rest for 10 minutes before slicing to allow filling to set, then serve warm.

Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.

Can I substitute ingredients in Sober Vegetable Tart?
