Description

A delicious vegan puff pastry filled with creamy caramelised onions, garlicky spinach, and a cheesy nutritional yeast blend. These golden, flaky pastries are perfect as a savory snack or appetizer, enhanced with warming spices and a touch of maple syrup for a slightly sweet finish.


Ingredients

Scale

Filling

  • 2 tbsp olive oil
  • 6-7 cups chopped spinach
  • 1 medium onion, thinly sliced
  • 2-3 garlic cloves, grated
  • 1/2 tsp thyme
  • 13/4 cup nutritional yeast
  • Salt, to taste
  • Chilli flakes, to taste
  • 1/8 tsp nutmeg (or a pinch)
  • 1/8 tsp black pepper (or a pinch)

Pastry and Glaze

  • 1 sheet puff pastry (pre-rolled)
  • 1 tbsp olive oil (for glaze)
  • 1/21 tsp maple syrup (optional, for drizzling)


Instructions

  1. Heat the olive oil and caramelise onions: In a pan, warm 2 tablespoons of olive oil over low to medium heat. Add the sliced onions and sauté, stirring frequently to prevent burning, until they are soft and caramelised.
  2. Add garlic, chilli flakes, and thyme: Mix in the grated garlic, chilli flakes to your taste, and thyme. Cook this combination for about 1 minute, allowing the flavors to meld.
  3. Cook the spinach: Pile the chopped spinach on top of the onion mixture in the pan. Cover with a lid and cook for 6 to 10 minutes until the spinach wilts.
  4. Reduce excess moisture: Continue cooking uncovered to evaporate most of the water released by the spinach.
  5. Finish the filling: Remove the pan from heat and stir in the nutritional yeast. Season with salt to taste. Let the mixture cool completely before assembling.
  6. Prepare puff pastry: Preheat your oven to 220°C (200°C fan). Lightly flour a clean workspace, then cut the pre-rolled puff pastry sheet into six squares.
  7. Assemble pastries: Spoon the cooled spinach and onion mixture onto one half of each pastry square. Fold the pastry over to form a triangle or rectangle, then seal the edges using a floured fork. Cut 2-3 slits on top to allow air to escape while baking.
  8. Chill pastries: Place the sealed pastries in the refrigerator for 10 minutes to firm up.
  9. Glaze and season: Combine 1 tablespoon olive oil with nutmeg and black pepper, then brush this glaze over the top of each pastry.
  10. Bake: Bake the pastries in the preheated oven for 30 to 35 minutes, or until they are puffed up and golden brown.
  11. Serve: Optionally drizzle with maple syrup for a hint of sweetness and enjoy warm.

Notes

  • The combination of caramelised onion and nutritional yeast gives a creamy, cheesy flavor while keeping the recipe vegan.
  • Adjust chilli flakes according to your spice preference.
  • Ensure the spinach mixture is completely cooled before filling the pastry to prevent sogginess.
  • Use a fork dusted with flour to seal the pastry edges to stop sticking.
  • Maple syrup drizzle adds a lovely sweet contrast but can be omitted if desired.
