What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to create a dish that’s rich in flavor and texture. Most of these are pantry staples, with a few fresh additions to elevate the dish.

• Puff pastry: Look for a vegan-friendly brand—most store-bought versions are accidentally vegan, but double-check the label.
• Cremini mushrooms: These add a deep, earthy flavor. You can substitute with portobello or button mushrooms if needed.
• Onion: Finely chopped for sweetness and depth.
• Garlic: Minced, for that irresistible aroma.
• Spinach: Fresh or frozen, wilted and drained to add a pop of color and nutrients.
• Bread crumbs: Helps to bind the filling; use gluten-free if needed.
• Balsamic vinegar: Adds tangy sweetness to balance the savory flavors.
• Fresh thyme: Or substitute with dried thyme; herbs make all the difference.
• Salt and pepper: To taste.
• Olive oil: For cooking the filling.
• Plant-based milk: For brushing the pastry to achieve that golden finish.

Feel free to get creative—add roasted chestnuts, chopped walnuts, or even sun-dried tomatoes for a twist.

Equipment Needed

• Skillet: For sautéing the mushroom filling.
• Rolling pin: To flatten and shape the puff pastry.
• Baking sheet: Make sure it’s large enough to hold your Wellington comfortably.
• Parchment paper: Prevents sticking and makes cleanup a breeze.
• Sharp knife: For scoring the pastry to create a decorative pattern.
• Pastry brush: For applying plant-based milk to the pastry for that golden sheen.

If you don’t have a rolling pin, a clean wine bottle works in a pinch! And while a pastry brush is ideal, you can use a spoon to gently spread the milk.

Preparation Method

1. Prepare the mushroom filling: Heat olive oil in a skillet over medium heat. Add the chopped onion and garlic, sautéing until fragrant, about 3 minutes.
2. Add the mushrooms: Stir in the cremini mushrooms, cooking until softened and most of the liquid has evaporated, about 8-10 minutes.
3. Season the mixture: Add balsamic vinegar, thyme, salt, and pepper. Stir well to combine. Remove from heat and let cool.
4. Wilt the spinach: In the same skillet, cook the spinach until just wilted. Drain any excess liquid and mix the spinach into the mushroom filling.
5. Add breadcrumbs: Stir breadcrumbs into the filling mixture to help bind it. Taste and adjust seasoning if necessary.
6. Roll out the puff pastry: On a lightly floured surface, roll out your puff pastry into a rectangle large enough to encase the filling.
7. Assemble the Wellington: Spoon the mushroom filling onto the center of the pastry, shaping it into a log. Fold the pastry over the filling, sealing the edges with a little water.
8. Create your design: Use a knife to score the top of the pastry lightly. Brush with plant-based milk.
9. Bake: Preheat the oven to 400°F (200°C). Place your Wellington on a parchment-lined baking sheet and bake for 25-30 minutes, or until golden brown.
10. Rest and slice: Let the Wellington cool for 5 minutes before slicing and serving warm.

Pro tip: If your pastry starts browning too quickly, cover it lightly with foil for the remainder of the baking time.

Cooking Tips & Techniques

• Don’t skip the cooling step: If the mushroom filling is too hot, it can make your pastry soggy.
• Seal the edges properly: Use a little water or plant-based milk to ensure the pastry doesn’t open up while baking.
• Use cold puff pastry: Warm pastry can tear or stretch too much. Keep it chilled until you’re ready to use it.
• Score for beauty: Lightly scoring the pastry creates a gorgeous, professional-looking finish.
• Watch your bake time: Every oven is different, so keep an eye on it to avoid over-browning.

Following these tips will help you achieve a perfect Wellington every time—crispy on the outside, tender and flavorful on the inside.

Variations & Adaptations

• Gluten-free option: Use gluten-free puff pastry and breadcrumbs.
• Seasonal twist: Add roasted root vegetables like butternut squash or sweet potatoes to the filling.
• Nutty addition: Mix in chopped walnuts or pecans for a crunch.

If you’re feeling adventurous, try adding some vegan cheese to the filling for an extra layer of richness. I once added a touch of truffle oil—game changer!

Serving & Storage Suggestions

Serve your Vegan Mushroom Wellington warm, sliced into generous portions. Pair it with a side of roasted vegetables, a crisp green salad, or even creamy mashed potatoes. For drinks, a glass of red wine or sparkling water with lemon complements the flavors beautifully.

To store leftovers, wrap them tightly and refrigerate for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through to maintain the crispiness of the pastry. You can also freeze the baked Wellington for up to 1 month; just thaw overnight before reheating.
