📋About the recipe

Have you tried your hand at a vegan Wellington before? This mushroom Wellington is certainly one of those recipes that will totally impress your guests! The golden outer crust, the crunch you get when you bite down on it, and the delicious healthy filling is going to steal the show. It’s similar to my Homemade Sausage Rolls.

Most importantly this lentil vegan wellington recipe has zero faffing around, it’s simple to make with accessible ingredients that won’t take up your whole day! While it may look like something you spent all day on, it really took a few minutes to prepare then 30 minutes in the oven.

So if you’re looking for vegetarian recipes for Christmas then make this vegan wellington!

🥘Ingredients to make Lentil Wellington

ingredient flatlay with mushrooms, lentils, chestnuts, mustard, tamari, garlic, tomato puree, gravy, rosemary, and thyme.
  • Lentils – Add the meatiness to this vegan wellington. They also contain good protein. If you have any tins spare then try making my Stuffed Butternut Squash recipe.
  • Mushrooms – Essential when making a vegetarian wellington for there umami meaty taste.
  • Chestnuts – A key ingredient in anything christmas. They add texture and extra flavour into this mushroom wellington.
  • Tamari – Is a gluten-free alternative for soy sauce.
  • Mustard – I use dijon mustard for it’s depth of flavour and hint of “spiciness”
  • Garlic – One of my go-to flavours – should be crushed.
  • Tomato Puree – Adds a umami flavour to this veggie wellington.
  • Gravy Granules – A secret weapon in this vegan wellington. It adds a real boost in flavour.
  • Rosemary – One of my favourite herbs. Check out my Rosemary Roast Potatoes.
  • Thyme – A versatile herb that works so well at Christmas time. If you have some spare then try making my Hasselback Potatoes.

💭Substitutions

If you haven’t got all the ingredients, here are a few swap suggestions.

  • Chestnuts – Try walnuts instead
  • Tamari – Soy sauce (if you’re not gluten-free)
  • Gravy granules – veg stock powder
  • Fresh herbs – dried herbs use 1 tbsp of each

👪Recipe FAQ’s

Below are some answers to commonly asked questions for this vegan Wellington.

Can I make this in advance of Christmas day?

Yes you can. I think it’s best served freshly baked but you can prepare it the day before (store in a sealed container at room temperature) and re-heat in the oven for 15-20 minutes.

Which pastry do you use?

I use the gluten-free Jus-Rol Puff Pastry (attached a photo in the top tips section below). It’s the most widely available in supermarkets.

Does it matter which mushrooms I use?

You will want to use a “meaty” mushroom for this mushroom wellington. Mushrooms such as cremini, button, and portobello are ideal for this.

💭Top Tips

  • I use the Jus-Rol gluten-free puff pastry (shown below). You can always use normal puff pastry if you don’t need it to be gluten-free. (This is NOT a sponsored recipe)
  • Be gentle when placing the pastry over the mix and also when crimping the edges with a fork!
  • Be sure to be gentle when scoring the pastry. If you’re looking to change things up, if you brush the pastry with olive oil before you score it, the score marks will stand out more. If you want more of a subtle pattern on your vegetarian Wellington, brush it after you score it. You can also score any decorative design you prefer. Regardless, it is important to score the Wellington to allow it to release steam as it bakes.
  • Allow to cool for 5-10 minutes before slicing so the moisture doesn’t evaporate immediately.
  • Slice with a cerated knife to easily cut through the pastry!

🍽Serving Suggestions

Some of my favourite sides to serve with this vegetarian Wellington are the following.

🥡Preparing ahead and storing

Yes you can prepare this ahead of Christmas day!

I think it’s best served freshly baked but obviously if this is for Christmas then there is a lot going on.

Simply cook as per the instructions and then store in a sealed container at room temperature.

Re-heat in the oven for 15-20 minutes until warm through-out.

Ingredients 

  • 2 sheets gluten free puff pastry, (I use Jus-Rol pictured above)
  • 200 g chestnut mushrooms, finely chopped (2 cups)
  • 150 g pre-cooked chestnuts , finely chopped (1 cup) (see notes for other ideas)
  • 2 tbsp tamari , (30ml) (see notes for other ideas)
  • 2x 400 g cans of pre-cooked lentils, drained and rinsed (4 cups)
  • 2 garlic cloves, crushed
  • 2 tbsp gluten free & vegan gravy granules/powder, (see notes for other ideas)
  • 2 tsp dijon mustard
  • 1 tbsp tomato puree
  • large sprig rosemary, finely chopped
  • large sprig thyme , finely chopped
  • olive oil

Instructions 

  • Firstly pre-heat your oven to 200C (390F)
  • Now to a large pan, add a drizzle of olive oil, 200g chopped mushroom, 150g chopped chestnuts and 2 tbsp Tamari and cook together for a few minutes until the mushrooms soften and brown off
  • Now add the drained lentils (make sure no excess liquid), 2 crushed garlic, 2 tbsp gravy powder, 1 tbsp tomato puree, 2 tsp dijon mustard, large sprig of rosemary and thyme finely chopped and mix
  • Cook together for a couple minutes, then take off the heat and allow to cool for 5-10 minutes
  • Meanwhile place your first pastry sheet onto a baking tray then spoon on the lentil mix making sure to not go right to the edges, give it some height I aim for 2 inches and keep it compact
  • Once the shape is formed (see the step by step photo in the photos above) place the next pastry sheet on top and press tightly round the edges
  • Cut off any excess pastry (save for shapes) then press round the edges with a fork before slicing a few lines into the top to release steam, now lightly glaze the top with olive oil
  • Place in the oven at 200C (390F) for 20 minutes until lightly golden, allow to sit for 5 minutes before slicing (make sure to cut carefully with a cerated knife)

    Made this today and it was amazing, so tasty! There’s so much flavour in it. I spread some cranberry sauce on the pastry before adding the mixture and this added some moisture but did not make the pastry soggy. I mistakenly only had 1 sheet of pastry so I halved the quantities and it still fed 3 hungry adults, could easily have served 4. Thanks so much, James!

  2. Could I make the stuffing separately and freeze ahead then defrost and assemble the Wellington Christmas morning?

  3. This looks (and smells) spectacular! I used walnuts instead of chestnuts and didn’t have tomato puree, so used home made chutney. It’s in the freezer to be eaten in early January for when family arrive (who may well be doing Veganuary). Great recipe, with very useful tips re scoring, etc.

  4. 5 stars
    I made this for the first time last Sunday and I’ve now earmarked it for Christmas lunch! It is so quick and easy to make and tastes scrummy! I love that it holds its shape when cut and the filling doesn’t fall out! It wasn’t all eaten on the day, so I heated slices up in the air fryer over the next few days and it tasted just the same as when first cooked! Thanks for much for a great recipe!

  5. Thank you for the delicious recipe. I have made vegan Wellington before many times but I’m going to use your recipe now for Christmas. The only problem now is that I’m allergic to most all gluten and wheat free vegan puff pastries because of the ingredients. I have found a pizza gluten and wheat free vegan flour. I’ve heard that it can substitute or is the closest thing to the puff pastry. Do you think it would work? Thanks

  6. Is there a reason why I cannot freeze it with pastry pre-baked if I cool the filling first before assembling?

    1. Hey Caroline, good question. I haven’t tested it that way so didn’t want to say about it. If this is something you have done before with other pastry recipes like this then I am sure it will be fine 🙂

  7. 5 stars
    Oooooo I’ve just made this, with a few tweaks. Added some dried cranberries and a dash of lemon juice.
    Wow it’s so tasty. Winner winner lentil dinner
    Well done James another excellent dish
    BTW CONGRATULATIONS

  8. Absolutely delicious. Tested this recipe for our family Sunday roast this weekend and in preparation for Christmas this year. The BEST vegan or vegetarian wellington I have made so far. Will be making it onto our Christmas table this year.
