Recipe Ingredients and Notes

Vegan Wellington with Lentils and Mushrooms

  • Filo Dough or Puff Pastry: The key here is making sure to find a vegan-friendly pre-made dough (typically in the freezer section)
  • Brown or Green Lentils: To add a meatiness to the dish without needing to add nuts (to make it allergy friendly!) You can replace the lentils with beans or chickpeas if you'd like as well.
  • Veggies: I used tomatoes, mushrooms and carrots but feel free to choose any mixture of veggies you like! I just would keep the mushrooms - when paired with the lentils it helps bind the filling and gives it a meaty texture.

How to Make Vegan Wellington - Step by Step

Step 1: Rinse lentils and add to a small saucepan with 2 cups of water. Bring to a boil. Lower the heat to medium-low and allow to simmer for 25 minutes. Once complete, set aside.

Step 5: Preheat oven to 400 degrees. Remove phyllo dough from fridge. Add one sheet of phyllo dough at a time on a baking sheet. Brush olive oil on each layer of phyllo dough as you add another sheet. The top sheet will not have olive oil brushed on it.

What Makes This Vegan Wellington Healthy?

  • High in Plant-Protein: Lentils are full of plant-protein and make for an excellent meat substitute. Each serving of this vegan mushroom wellington has 11 grams of protein.
  • Rich in Vitamins and Nutrients: This mushroom wellington recipe is packed with veggies! Mushrooms are high in copper, potassium, magnesium, zinc and a number of B vitamins such as folate, and tomatoes are rich in inflammation-reducing antioxidants.
  • Healthy Fats: Using both coconut oil and olive oil gives you lots of healthy fats. Healthy fat is vital for strong hair and glowing skin.

Will Kids Enjoy This Vegan Wellington?

You won't believe your eyes when you see your kids devour every crumb of this and ask for more. The flaky pastry bakes up nice and crispy along with the balanced flavors of the filling is a nice balance for kids. Your kiddos will be content with the mild flavors and you can feel good about feeding them something filling and healthy.

For pickier kids, I recommend adding less stuffing to this vegan beef wellington, and serving them a smaller portion to start. Once they get used to it, you can serve them more of a regular "adult" portion!

Recipe FAQs

Is Puff Pastry or Phyllo Dough Vegan?

The good news is - yes! Most pre-made puff pastries or frozen phyllo dough is vegan. Wewalka makes a good quality, vegan friendly puff pastry, and every phyllo dough brand I've come across has been vegan friendly.

Can I make This Vegan Mushroom Wellington ahead of time?

Definitely! Follow the recipe as written and prepare the vegan wellington up to the baking point. Right before baking, wrap it in plastic wrap and place it in an airtight container in the fridge. Before baking, let the mushroom wellington come to room temperature and then place it in the oven (400 degrees for 25 minutes)

How to Store and Keep

While this vegan wellington can be saved for leftovers, it tastes better when it's served fresh. The phylo dough can lose its crispiness after it's been sitting or refrigerated.

If you happen to have leftovers, allow them to cool completely. Then transfer to a glass air tight food storage container and refrigerate for up to 3 days. Keep in mind that the dough may become a little bit soggy as it sits.

Reheat in the oven or air fryer to allow the phyllo dough to crisp back up. If you reheat in the microwave you will have soggy dough. Heat in the oven or air fryer at 325 degrees for 10 minutes or so until it's hot.

How to Serve

Serve this vegan wellington recipe at your holiday or Thanksgiving meal as the main dish! It pairs perfectly with mashed potatoes, and roasted vegetables, topped with vegan gravy.

Top Tips For Making Vegan Wellington

  • Chop, slice, and halve your veggies ahead of time and store them in the fridge for up to 2 days before making this vegan wellington. It's an easy way to meal prep.
  • Score the top of the phyllo dough to add some character to the dish. As an added bonus, it will also help release some of the steam.
  • The mushroom wellington is best eaten as soon as it comes out of the oven as the pastry will start to soften as the mushrooms release their juices as they cool.
  • Roasted potatoes or mashed potatoes are a wonderful accompaniment to this dish.
  • If your pastry sheet is frozen, be sure to thaw it for about 30 minutes before rolling it out and spreading olive oil on it.
