Step‑by‑Step Instructions for Vegan Spinach and Caramelized Onion Puff
Step 1: Caramelize the Onions
In a large skillet, heat 2 tablespoons of olive oil over low to medium heat. Add the thinly sliced onions and sauté them gently for 15-20 minutes, stirring occasionally, until they’re soft and golden brown. The key is to allow them to develop that rich sweetness without burning, creating a flavorful base for your Vegan Spinach and Caramelized Onion Puff filling.
Step 2: Add Flavor Enhancers
Once the onions are beautifully caramelized, stir in 2 cloves of freshly grated garlic, a pinch of chili flakes, and a sprinkle of fresh thyme. Cook this mixture for an additional minute until the garlic becomes fragrant, which will elevate the flavors in your filling. The combination of these ingredients will add depth to the savory filling.
Step 3: Incorporate Spinach
Next, add a generous amount of chopped spinach to the pan. Cover the skillet and let the spinach wilt for about 6-10 minutes, stirring occasionally. Once wilted, remove the lid and cook off any excess moisture, ensuring the filling is not too wet, which is crucial for a crispy Vegan Spinach and Caramelized Onion Puff.
Step 4: Season the Filling
After the spinach has cooked down, transfer the mixture to a bowl and let it cool slightly. Mix in ¼ cup of nutritional yeast, the appropriate amount of salt, a dash of nutmeg, and freshly cracked black pepper to taste. This step will bring out the cheesy flavor without any dairy and create a well-seasoned filling that complements the caramelized onions beautifully.
Step 5: Prepare the Puff Pastry
Preheat your oven to 220°C (200°C fan). While the oven heats, roll out a sheet of vegan puff pastry on a floured surface, cutting it into 6 equal squares. The squares should be big enough to hold a spoonful of the savory spinach and caramelized onion filling, forming the base of your delightful Vegan Spinach and Caramelized Onion Puff.
Step 6: Assemble the Pastries
Spoon a portion of the cooled spinach and onion filling onto one half of each pastry square. Carefully fold the other half over the filling and press to seal the edges. For an extra decorative touch and to ensure a firm seal, use the tines of a fork to crimp the edges, giving your Vegan Spinach and Caramelized Onion Puff a beautifully finished look.
Step 7: Chill and Bake
Place the assembled puffs on a baking sheet lined with parchment paper. Chill them in the fridge for about 10 minutes while the oven finishes preheating. Just before placing them in the oven, brush the tops with a little olive oil for that golden finish. Bake for 30-35 minutes or until they puff up beautifully and achieve a lovely golden brown color.
Step 8: Serve and Enjoy
Optionally, drizzle a touch of maple syrup over your flaky Vegan Spinach and Caramelized Onion Puffs just before serving. The sweet contrast enhances the savory flavor profile and adds a gourmet touch, perfect for impressing guests or treating yourself to a delightful snack.
