🍄 INGREDIENTS (WITH SUBSTITUTIONS)

ingredients-vegan-mushroom-wellington
  • Puff Pastry – Store-bought puff pastry is easiest. I use Pepperidge Farm Puff Pastry Sheets which are 100% vegan.
  • Mushrooms – you can use any kind or mushrooms for the mushroom filling: Portobello mushrooms, cremini mushrooms, porcini or Baby Bella mushrooms also known as white button mushrooms. Also, if you love mushrooms, try my Vegan Mushroom Stroganoff or my sticky Shiitake Mushrooms Recipe.
  • Olive Oil – extra-virgin olive oil is best for this recipe, however, if unavailable, you can use melted vegan butter. 
  • Garlic – fresh minced garlic adds a savory flavor to the sweet potato mushroom blend. If fresh is unavailable, you can substitute with garlic powder.
  • Onion – I prefer using sweet, yellow onions in this Vegan Mushroom Wellington, however, any type of onion will work.
  • Coconut Sugar – used to caramelize the onions. If you don’t have coconut sugar on hand, you can use organic brown sugar.
  • Sweet Potato – I stick these in the microwave for 3-4 minutes, then allow them to cool. Once room temperature, remove the flesh from the skins and mash in a bowl.
  • Dijon Mustard – adds a pungent, spicy flavor to the mushroom mixture that pairs really well with the other ingredients. If unavailable, you can use any kind of yellow mustard. 
  • Rosemary – or other fresh herbs like thyme or sage.
  • Vegan Egg Wash – this is made by mixing aquafaba (chickpea brine), plant milk, vegetable oil and maple syrup in a small bowl. You can also use olive oil instead.

🔪 STEP-BY-STEP INSTRUCTIONS

Before you begin making Vegan Mushroom Wellington, remove a single puffed pastry from the freezer and set it on a baking sheet lined with parchment paper. Allow it to thaw for 25-30 minutes while you’re preparing your ingredients.

Step 1: Add olive oil to a medium skillet. Sauté the onion over medium heat until the onions are translucent.

vegan-mushroom-wellington-41

Step 2: Once translucent, add coconut sugar and increase to medium-high heat to caramelize. Cook until brown and slightly crispy. Remove from pan and set aside.

Step 3: Heat olive oil in a small saucepan. Sauté sliced mushrooms and minced garlic in the olive oil until they are brown and slightly crispy.

Step 4: Set mushrooms on a plate lined with several paper towels. Fold paper towels completely around mushrooms, turn over and let them sit to absorb excess moisture.

Step 5: Carefully unfold puffed pastry onto parchment paper (you may also use a lightly floured surface). You may use a rolling pin to spread the dough out a little if you want. Spread the caramelized onions over the center of the puff pastry leaving about a 3/4 inch border at the edge of each side of the pastry.

Step 6: Next, top with mashed sweet potato.

Step 9: Carefully roll the pastry over the top of the mushroom mixture until you have a lovely log. Press down to seal the edges.

Step 10: Gently roll the log over so the seam is on the bottom.

Step 11: In a small bowl, whisk together ingredients for vegan egg wash. Using a pastry brush, brush the top of the pastry with a light coat. Using a sharp knife, cut lines across the pastry one way, and then the other in a cross-hatch pattern. Place in freezer for 10 minutes. Remove and reapply a thin coat of vegan egg wash.

Step 12: Bake in a preheated oven at 375F/191C degrees for about 40 minutes, depending upon your oven. It’s done when the crust turns a nice, golden brown. Remove from oven and allow to cool for 10 minutes before slicing. And, by all means, enjoy!

👩🏻‍🍳 EXPERT TIPS

  • This vegan mushroom wellington is best served right out of the oven, but, as long as you drain the mushrooms properly, you can cover with foil or plastic wrap and stick in the refrigerator until you’re ready to cook it.
  • You can also cook it ahead of time and stick in back in fridge until ready to serve.
  • If you don’t have ingredients for vegan egg wash, just use olive oil.
  • For best results, use a sharp knife for slicing.
  • To prevent the edges of the pastry from burning, or becoming more done than the top, place foil over them during the last 10 minutes of the baking process.

💭 Frequently Asked Questions

Is puff pasty vegan?

Not all brands of puff pasty are vegan. However, Pepperidge Farms is naturally vegan and widely available in the USA.

Can I make this recipe ahead of time?

Yes. Simply follow the instructions above and bake 1 or two days ahead of time. Remove from oven and allow to cool to room temperature. Wrap tightly in plastic wrap and refrigerate. To reheat, place on a baking tray and heat in the oven at 350F/177C until heated through.

How do I reheat leftovers?

I have reheated leftovers in the microwave, because I didn’t want to wait for them to reheat in the oven. You can do this, however, it will change the texture of the loaf. For best results, reheat slices on a baking sheet at 350F/177C for about 10-12 minutes.

Vegan Mushroom Wellington can be stored in the refrigerator for up to 5 days after being cooled to room temperature, wrapped in plastic wrap and placed in an airtight container.

To reheat, place slices on a baking sheet and heat through 350F/177C for about 10-12 minutes.  Alternatively, you can reheat slices in the microwave, however, doing so will change the texture of the vegan wellington.

Freezing is NOT recommended.

    I love this mushroom Wellington recipe; it is so easy to make and absolutely delicious. One of our family favourites. Thank you for sharing this recipe!

    1. I have never froze it before but not sure I’d recommend as the pastry dough may get soggy with all the ingredients in it, especially the mushrooms. Thank you for your comment

    Hi Deborah!!
    I was so excited to see this recipe, I’m going to make it for the vegans in the family for Christmas dinner. It looks tasty and I can’t wait to cook one of your creations ❣️

    1. Hey Beth. How awesome to read your comment. Thanks so much. Please take a picture and tag #veganvigilanteblog on Instagram. I’d love to see it. Hope your doing great. Miss you.

      1. I don’t understand why you don’t put it in a proper pie plate or something similar and I especially don’t understand why you’d waste so much paper towels to dry them given mushrooms are 100% tastier if the water is cooked out of them and they’re caramelized too. The ingredients make sense but nothing else does IMO.

        1. Mike. You criticize the recipe yet you’re never even tried it? The mushrooms are caramelized in the recipe. Wasting paper towels? Proper pie plate? It’s not a pie I don’t get what you mean. The recipe is delicious. It’s been kitchen tested and replicated by others. Maybe just give it a try before you criticize it.

    I’m in the middle of making this and find myself confused. The recipe says to spread half the onions on the pastry but there is no mention of what to do with the other half. Can you clarify this for me please. Melanie.

    1. Hi Melanie. Sorry for the confusion. There is a picture in the step by step that shows that you should spread all the mushrooms over the middle of the dough. You have to leave room on the edges for folding. Does that make sense? I see where it says half of the mushrooms in the recipe card and I changed that. Thanks for pointing that out. I again apologize. If you look at the step by step pictures, and still have questions, please get back to me. I’m here all day.

    Made it on the weekend and it was delicious. Decided it will be our main for Christmas lunch. Was so easy!!! And I’m not the best of cooks.

  5. 5 stars
    What a gorgeous looking recipe and it makes a wonderful sounding appetizer. It certainly would steal the show on the appetizer tray. Vegans can certainly be grateful for this recipe but it has so much flavor going on that anyone would be happy to enjoy it. A beautiful presentation.

    1. Last night, I had to run out and put it in the fridge. When I came home, I just sliced a couple of pieces and threw them in microwave and they came out great. Hope that helps and thanks for such a great question. If microwaving slices, only heat for about 1 minute or it gets too soft. To maintain its flakiness and crispiness, it’s best reheated in oven. You can cover with foil to prevent over-browning crust.

        Thanks so much! What temp and how long do you reheat in the oven? I want to bring this to a Xmas party. This is a great recipe!

        1. Good question, Danielle. I would heat it for about 20 to 30 minutes on say 300 degrees. Cover it with foil to keep it from getting too brown. Maybe remove last 5 minutes or so to keep it crisp and flaky.

    1. Cheese Curd in Paradise, what is your name, anyway? I know you’ll love it if you try it. Thanks for commenting.
