How to Make Vegan Mushroom Wellington
-
Caramelize Onions: Heat olive oil in a pan over medium-low heat, adding onions seasoned with salt and pepper. Cook for 15-20 minutes until the onions turn golden brown and fragrant.
-
Sauté Spinach: In the same pan, toss in the baby spinach and sauté until wilted, about 3-4 minutes. Remove from heat and let cool completely.
-
Cook Mushrooms: Increase the heat and add the portobello mushrooms to the pan. Sear for about 5 minutes on each side until they’re golden brown. Afterwards, place on paper towels to drain excess moisture.
-
Cool Ingredients: Transfer the cooked onions, spinach, and mushrooms to the refrigerator so they can cool completely; this keeps the pastry from becoming soggy.
-
Prepare Pastry: Preheat your oven to 200°C (390°F). Roll out the vegan puff pastry on a lined baking sheet, layering the caramelized onions, sautéed spinach, and cooked mushrooms. Sprinkle thyme and additional seasoning atop the filling.
-
Assemble Wellington: Carefully fold the pastry over the filling, sealing the edges tightly. Brush the top with the prepared vegan egg wash and place it in the freezer for 10 minutes to set.
-
Bake: Pop the wellington into your preheated oven and bake for 30-35 minutes or until the pastry is gloriously golden and crispy.
Optional: Serve with a side of crispy roast potatoes for an unforgettable meal.

How to Store and Freeze Vegan Mushroom Wellington
-
Room Temperature: It’s best to enjoy your Vegan Mushroom Wellington fresh out of the oven, but if you must leave it out, it can sit at room temperature for up to 2 hours.
-
Fridge: Store leftover slices in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the oven to maintain the pastry’s crispiness.
-
Freezer: You can freeze the unbaked wellington for up to 2 months. Wrap tightly in plastic wrap and foil before placing it in a freezer-safe container. Bake from frozen, adding extra time to the baking process.
-
Reheating: To reheat, place slices in a preheated oven at 180°C (350°F) for about 15-20 minutes, until heated through and the pastry is crispy again.
Expert Tips for Vegan Mushroom Wellington
- Keep it Chilled: Ensure all ingredients, including the puff pastry, are chilled before assembling. This crucial step helps prevent the pastry from becoming soggy.
- Avoid Pre-Made Onions: Making your own caramelized onions adds depth and flavor. Pre-made versions can lack the sweetness and richness needed for this Vegan Mushroom Wellington.
- Watch the Bake Time: Keep an eye on the baking process; every oven varies. Aim for a golden, flaky crust, and avoid overcooking to ensure the filling remains juicy.
- Customize Your Fillings: Feel free to experiment with different mushrooms or herbs. Mixing shiitake or baby bellas into your filling can elevate the taste profile of your Vegan Mushroom Wellington.
- Serve Immediately: This dish is best enjoyed fresh out of the oven, as the pastry retains its crispness. Have your guests ready to dig in as soon as the wellington is baked!

Make Ahead Options
Preparing the Vegan Mushroom Wellington in advance can save you precious time, especially during busy holiday gatherings! You can make the filling (caramelized onions, sautéed spinach, and cooked portobello mushrooms) up to 3 days ahead of time—just store it in an airtight container in the refrigerator to maintain freshness. Additionally, after assembling the Wellington, wrap it tightly in plastic wrap or foil and refrigerate it for up to 24 hours before baking. To keep the crust perfectly crisp, ensure the filling is cool before wrapping. When you’re ready to serve, simply bake the wellington right from the refrigerator, adding a few extra minutes to the baking time for that golden, flaky crust you crave!
Vegan Mushroom Wellington Recipe FAQs
How do I choose ripe and fresh portobello mushrooms?
Absolutely! Look for portobello mushrooms that are firm to the touch and have a smooth, unbroken surface. They should be dark brown in color without any dark spots—these indicate that they’re past their prime. If possible, buy mushrooms that are similar in size for even cooking.
What’s the best way to store leftover Vegan Mushroom Wellington?
Very good question! To keep it fresh, store leftover slices in an airtight container in the refrigerator for up to 3 days. Make sure it’s completely cooled before sealing to avoid condensation that can make the pastry soggy. When it’s time to enjoy the leftovers, simply reheat in a preheated oven to maintain that crispiness!
Can I freeze the Vegan Mushroom Wellington?
Yes indeed! You can freeze the unbaked Wellington for up to 2 months. To do this, wrap it tightly in plastic wrap and then in foil to prevent freezer burn. When you’re ready to bake, remove the wrapping and place it in the oven directly from the freezer, adding approximately 10-15 minutes to the baking time.
What should I do if my pastry becomes soggy?
If you find your pastry turning soggy, there are ways to troubleshoot! First, ensure all your filling ingredients are cooled completely before assembling, as excess moisture can seep into the pastry. If you notice it’s soggy after baking, you can place it back in the oven for a few more minutes to help firm it up again.
Is this recipe suitable for someone with nut allergies?
Yes! While the standard recipe calls for almond or cashew milk in the egg wash, you can easily use other plant-based milks like oat or soy milk as a substitute. Just make sure to double-check any pastry brand for nut contents if you’re sensitive.
Can I make the Vegan Mushroom Wellington ahead of time?
Absolutely! This Wellington can be prepared ahead of time and stored in the refrigerator for up to 24 hours before baking. Just remember to cover it tightly with plastic wrap to keep the pastry from drying out. When you’re ready to bake, remove the plastic and simply pop it in the oven!
