How to Make Vegetable Wellington
-
Sauté Vegetables: Begin by heating a skillet over medium heat. Add finely chopped onions and mushrooms, stirring often until the moisture evaporates and the mixture becomes golden brown, about 10-15 minutes.
-
Cool Filling: Once caramelized, remove the skillet from heat. Transfer the vegetable filling to a bowl and allow it to cool completely. This step is crucial for preventing a soggy pastry!
-
Wrap Filling: Take the thawed puff pastry and roll it out on a lightly floured surface. Place the cooled vegetable filling in the center, and fold the edges over to encase the filling completely.
-
Prepare for Baking: Brush the wrapped pastry with an egg wash for a beautiful golden color. Use a sharp knife to score a few slits on top, creating vents for steam to escape.
-
Bake: Preheat your oven to 400°F (200°C). Place the Wellington on a baking sheet lined with parchment paper and bake for 25-30 minutes, or until the pastry is puffed and golden brown.
Optional: Serve with a drizzle of balsamic reduction for an extra touch of flavor.

Make Ahead Options
These Vegetable Wellington are perfect for meal prep enthusiasts! You can prepare the vegetable filling up to 3 days in advance; just sauté your mushrooms and onions as directed, then let the filling cool completely before transferring it to an airtight container in the refrigerator. When you're ready to serve, simply wrap the cooled filling in the thawed puff pastry, brush with egg wash, and bake right before serving. This method not only saves you precious time on busy nights but also ensures that the pastry stays just as flaky and delicious when baked fresh. Trust me, these delightful Wellington will taste just as scrumptious, even when prepped ahead!
How to Store and Freeze Vegetable Wellington
Fridge: Store leftover Vegetable Wellington in an airtight container for up to 3 days. Ensure it's fully cooled before sealing to maintain crispiness.
Freezer: Wrap the Wellington tightly in plastic wrap and aluminum foil for up to 3 months. Thaw overnight in the fridge before reheating for best results.
Reheating: To reheat, place the Vegetable Wellington in a preheated 350°F (175°C) oven for about 15-20 minutes or until warmed through and crispy again.
Chef's Helpful Tips
- When making Vegetable Wellington, always ensure your vegetables are sautéed until fully cooked and the moisture has evaporated to avoid a soggy bottom.
- Be patient and allow the filling to cool completely before wrapping it in puff pastry; this step prevents steam buildup that can compromise the pastry's texture.
- When rolling out the puff pastry, keep your work surface lightly floured to avoid sticking, and use a sharp knife to score the top for steam vents, which helps in achieving an evenly baked crust.
- Finally, preheat your oven to 400°F to ensure the pastry rises beautifully and turns golden brown in 25-30 minutes of baking.
Vegetable Wellington Recipe FAQs
What kind of mushrooms should I use for Vegetable Wellington?
Absolutely! I recommend using cremini or button mushrooms as they provide a lovely earthy flavor. If you're feeling adventurous, add a mix including shiitake or portobello for a richer taste. The key is to ensure they are fresh and not slimy or darkened by age; they'll be perfect for a savory filling!
How should I store leftover Vegetable Wellington?
Very good question! After enjoying this delightful dish, store any leftovers in an airtight container in the fridge for about 3 days. Ensure it's completely cooled before sealing to keep the pastry crispy. You can always reheat it in the oven for about 15-20 minutes to restore its lovely texture!
Can I freeze Vegetable Wellington?
Yes, you can! To freeze your Vegetable Wellington, wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It will stay fresh for up to 3 months. When you're ready to enjoy it again, simply transfer it to the fridge to thaw overnight, and then reheat in a preheated oven at 350°F (175°C) for about 15-20 minutes until it's crispy and warmed through.
What should I do if my puff pastry isn’t rising?
Don't worry, this can happen! If your puff pastry isn't rising, first ensure it was kept cold before baking, as warmth can cause it to flatten. Also, make sure to score the top for steam to escape; without vents, the pastry might not puff up as expected. Lastly, always preheat your oven to the right temperature—around 400°F (200°C)—for that perfect puff!
Is this Vegetable Wellington suitable for vegetarians and vegans?
Yes, the Vegetable Wellington can easily be made vegetarian, and it's naturally vegan if you substitute the egg wash for a plant-based option, like almond milk or aquafaba (the liquid from chickpeas) for brushing the pastry. Just ensure any additional ingredients align with your dietary preferences!
Can I change the vegetable filling?
Absolutely! The more the merrier! Feel free to experiment with different vegetables like spinach, carrots, or bell peppers. Adding herbs like thyme or rosemary can elevate the flavor profile, making it uniquely yours. Just sauté them well until moisture is reduced for the best results!
