Directions
I love making this Vegan Portobello Wellington for guests because it’s just as satisfying as it is elegant. Follow my step-by-step directions for a flaky golden Wellington that’s bursting with vibrant plant-based flavors.
Prep the Portobello Mushrooms
- Gently wipe each portobello mushroom cap with a damp towel to remove any dirt.
- Remove stems and, if desired, carefully scrape out the gills with a spoon for a smoother texture.
- In a shallow bowl, whisk together 2 tablespoons olive oil and 1 tablespoon balsamic vinegar.
- Place the mushroom caps in the mixture and coat both sides.
- Sprinkle with a pinch of salt and pepper. Let them marinate for 15 minutes while you prep the filling.
Prepare the Filling
- Heat 1 tablespoon olive oil in a large skillet over medium heat.
- Sauté 1 finely chopped onion for 3 to 4 minutes until translucent.
- Add 2 minced garlic cloves and cook for 1 minute until fragrant.
- Stir in 3 cups fresh spinach. Sauté until wilted and bright green, about 2 minutes.
- Add 1/2 cup chopped walnuts, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
- Cook, stirring often, until walnuts are toasted, about 2 minutes.
- Turn off the heat. Let the mixture cool for 10 minutes before continuing.
Assemble the Wellington
- Preheat your oven to 400°F. Line a baking sheet with parchment paper.
- On a lightly floured surface, roll out your vegan puff pastry into a rectangle about 1/8-inch thick.
- Spread the cooled filling in the center of the pastry, leaving a 2-inch border on all sides.
- Place the marinated portobello caps, gill-side down, on top of the filling in a single layer.
Wrap in Puff Pastry
- Fold the long edges of the pastry over the mushrooms.
- Fold the short ends over to seal the package. Press gently to seal any gaps.
- Place the Wellington seam-side down on the prepared baking sheet.
- If desired, brush the pastry with a bit of plant-based milk for a golden finish.
- Use a sharp knife to cut a few diagonal slits on top for steam to escape.
Bake the Wellington
- Bake in the preheated oven for 30 to 35 minutes, until the pastry is puffed and golden brown.
- Remove from the oven and let rest for 10 minutes before slicing.
- Cut into thick slices using a sharp serrated knife and serve warm.
Make-Ahead and Storage Tips
I often recommend prepping Vegan Portobello Wellington in advance, especially for busy weeknights or hosting dinner guests. You can fully assemble the Wellington up to one day before you plan to bake it. After assembling, place the wrapped Wellington on a parchment-lined baking sheet, then cover it tightly with plastic wrap. Store it in the refrigerator until ready to bake.
If you want to freeze the Wellington, assemble it completely but refrain from baking. Wrap it tightly in plastic wrap and then in aluminum foil. Label with the date, then transfer it to the freezer. The unbaked Wellington can be frozen for up to one month. When ready to bake, let it thaw in the refrigerator overnight. Bake cold straight from the refrigerator, adding an extra 10 to 15 minutes to ensure the pastry cooks all the way through and gets that golden, flaky texture.
For storing leftovers, let the baked Wellington cool to room temperature. Wrap any remaining slices in foil or place in an airtight container. Refrigerate for up to three days. To reheat, place slices on a baking sheet and warm in a 350°F oven for 10 to 15 minutes until hot and crisp. Reheating in the oven keeps the pastry crispy rather than soggy.
If you want to prep components, the mushroom filling can be sautéed up to two days ahead and stored in an airtight container in the fridge. The filling can even be frozen for up to one month, then thawed before assembling the Wellington.
Below is a quick reference for planning ahead and storing your Vegan Portobello Wellington:
| Step | Storage Method | Max Time | Notes |
|---|---|---|---|
| Assembled, unbaked | Refrigerator | 1 day | Wrap tightly and cover with plastic |
| Assembled, unbaked | Freezer | 1 month | Wrap in plastic, then foil |
| Baked leftovers | Refrigerator | 3 days | Store in airtight container |
| Filling only | Refrigerator/Freezer | 2 days/1 month | Reheat and assemble when needed |
These make-ahead and storage strategies allow you to spend less time in the kitchen and more time enjoying nourishing, flavorful vegan meals with friends and family.
Serving Suggestions
I love serving my Vegan Portobello Wellington as the centerpiece of a balanced vegan feast. The flaky pastry and savory mushroom filling always look stunning on a large platter garnished with fresh herbs like thyme or rosemary. For a holiday table, I arrange thick slices on a large wooden cutting board surrounded by roasted seasonal vegetables like carrots, parsnips, or Brussels sprouts.
To make a complete meal, I pair slices of Wellington with a creamy vegan gravy or homemade mushroom sauce. A vibrant side salad with arugula, cherry tomatoes, and toasted walnuts offers bright, fresh flavors that balance the richness of the dish. When I want something even cozier, I serve the Wellington with garlic mashed potatoes or sweet potato purée.
If you are hosting a dinner party, you can cut the Wellington into individual portions before plating for a more elegant effect. I sprinkle each slice with microgreens and a drizzle of aged balsamic or beet reduction for added color and tang. For casual family meals, leftover slices reheat beautifully in the oven—just a few minutes bring back that satisfying crispness in the pastry.
