Mushroom Wellington - a #vegetarian twist on the classic Beef Wellington #recipe | via

Recently I was approached by Australian Mushroom Growers to join the Mushroom Masters Tournament of Taste.  Mushroom Masters is an annual competition between select bloggers in Australia, Canada and the United States who each week come up with delicious recipes showcasing mushrooms as the key ingredient.  As a huge mushroom fan how could I say no?

This week is the Dinner battle, and for dinner I wanted to come up with something that showcased the amazing flavour and versatility of mushrooms by making over a traditional meat dish into a delicious vegetarian recipe.  So I created a Mushroom Wellington!

We are all familiar with Beef Wellington, however I thought a Mushroom Wellington would be a great vegetarian re-interpretation of this classic recipe. Delicious and healthy mushrooms centre stage in this recipe it’s hearty enough to satisfy any meat eater. Even my husband!

Juicy portobello mushrooms surrounded by spinach and caramelised onions all encased in flaky and golden puff pastry.  What’s not to love about this mushroom wellington?

Here are a few more reasons to enjoy mushrooms:

  • Mushrooms are very low in calories mainly due to the fact they are 80 to 90% water
  • They are high in potassium, which helps lower blood pressure and reduce the risk of stroke.
  • Mushrooms are low in sodium, plus their umami counterbalances saltiness and allows for less salt to be used in a dish without compromising flavor.
  • They are high in copper which helps in the formation of red blood cells.
  • Mushrooms are high in selenium – a powerful antioxidant that plays a role in immunity.

UPDATE: My Mushroom Wellington won the Mushroom Masters Dinner Duel.  Thank you SO much to everyone who voted!!!

Vegetarian Mushroom Wellington recipe
Prep time
Cook time
Total time
Serves: 4
  • 6 medium or 4 large portabello mushrooms, stalks trimmed and cleaned
  • 3 onions, peeled and chopped
  • 2 tablespoons of olive oil
  • 2 tablespoons of butter
  • 300g of baby spinach
  • 4 sprigs of thyme
  • 1 sheet of frozen puff pastry, partially thawed
  • 1 egg, beaten
  • 1 tablespoon of dijon mustard
  • salt and pepper to taste
  1. Place a large frying pan over a medium heat. When the pan has come up to heat add olive oil followed by onion and reduce heat to low. Season with salt and pepper and cook for 15 to 20 minutes, stirring occasionally, until the onions are golden brown. Set aside to cool.
  2. Return the pan to the heat and add the baby spinach and cook until wilted. Remove from the baby spinach from the pan and set aside to cool.
  3. Return the pan to the heat again and increase the heat to medium. Add butter and when the butter has melted and started to froth add the mushrooms, top side down. Season with lightly with salt and pepper, and cook for a 5 minutes or until golden, before turning over and cooking for a further 5 minutes. Once both sides have been browned remove from the heat and brush both sides of the mushrooms with dijon mustard.
  4. Preheat the oven to 200 degrees Celsius (390 Fahrenheit). When the ingredients are cooled (you can pop them in the fridge to speed up the process) place a sheet of baking paper on the baking tray and then place the puff pastry sheet on top. Spread the caramelised onions over the middle third of the pastry, making sure to leave 1 to 2cm at the edges. Top with half the baby spinach and then the mushrooms. Finally, top the mushrooms with thyme sprigs and the remaining baby spinach.
  5. Very carefully roll the pastry over the top of the mushroom mixture until you have a log. Tuck the edges under the pastry, ensuring the seam is facing the bottom.
  6. Cut 2 holes in the middle of the pastry to allow steam to escape and very lightly coat with the egg wash. Place the pastry in the freezer for 10 minutes before repeating with another layer of egg wash and freezing the pastry for a further 10 minutes.
  7. Place the pastry back on the baking sheet and tray and place in the oven for 30 to 35 minutes, or until golden.
