Mushroom, Lentil & Nut Wellington

An easy vegan mushroom, lentil and nut wellington made with ready rolled puff pastry. Perfect for special family gatherings like Sunday dinner, Thanksgiving and Christmas dinner.

Mushroom, Lentil & Nut Wellington

Just look at that mushroom, lentil and nut wellington. 

Now imagine it on a plate with just-cooked roast potatoes, all crispy on the outside and fluffy inside. On the side there is a selection of  vegetables. Now pick up the gravy jug and pour rich onion gravy over the wellington.

You're in your happy place now aren't you? I know I am.

Who could resist such a meal?

We won't mention my brother-in-law Lachlan who doesn't like mushrooms, because that's just plain odd, isn't it?

Psssst! Don't tell him I called him odd. He won't stumble across this recipe, not when it has mushroom in the title, so if he finds out I'll know who to blame.

Vegan Wellington

A traditional wellington is made with steak, pate and mushrooms in puff pastry. A thin crepe is often used between the pastry and filling to stop moisture leaking into the pastry, but I've found no need to do that with this vegan version.

This vegan mushroom wellington is a crisp, golden puff pastry pie stacked full of flavour and texture. 

Layers of hummus, wilted spinach, mushroom pate and a mixture of thyme scented mushrooms, lentils and nuts. 

It's the perfect family dish to serve for Sunday dinner or for special occasions such as Thanksgiving and Christmas where everyone is gathered around the table to enjoy good food and good company.

How to get the most flavour from Mushrooms

To get the best out of mushrooms and bring out all the flavour, you just need to take a little care. Before you think about cooking them you need first need to prepare them. NEVER and I mean never soak mushrooms as they will just end up wet and won't brown and take on all that lovely flavour. 

Peeling Mushrooms

My advice is to trim the stem and peel the mushrooms. You can clean with damp kitchen paper, but to be honest it is easier to just peel them catching the edge near the stalk and peeling towards the top of the mushroom dome. A small vegetable knife useful for this. You choose the method, but NEVER soak them!

Best way to cook mushrooms

Gently saute the mushrooms in a frying pan with a little olive oil over a gentle to medium heat. It really is worth taking your time with mushrooms.

The most important thing is to season mushrooms while they are cooking. The soak it up and taste wonderful. You can also add garlic, fresh or dry herbs, red or white wine and vegetable stock or sometimes just a crumble of stock cube for added flavour.

Vegan cooked breakfast with mushrooms, tattie scones, veggie sausages and baked beans

Mushrooms in a cooked breakfast

When I cook mushrooms to serve on toast or as part of a vegan cooked breakfast, I cook the mushrooms in a little olive oil and season with salt in pepper. It's best to keep the flavours simple and let the mushroom flavour shine.

Creamy mushroom sauce for pasta

When I'm making a creamy mushroom sauce for pasta, I cook the mushrooms with garlic, season them with black pepper. After they've been cooking for a few minutes and released their juices,  I add white wine, fresh herbs and sometimes a crumble of vegetable stock cube (not a whole cube, from a pinch to half depending on how much sauce I am making), then cook them gently for a few more minutes until most of the liquid has thickened. I then add the soya cream & creme fraiche. Delicious doesn't cover it.

Mushrooms in a rich stew or sauce

When I'm making a rich tomato based sauce or stew, I cook the mushrooms with garlic, salt and pepper, then add red wine and dried herbs, before adding the other ingredients.

Mushroom Wellington

For this mushroom wellington, I added the mushrooms to sauteed chopped onion and garlic and continued to cook gently, seasoning the mushrooms as they cooked. I then added thyme (you can use fresh or dried), wine and half a vegetable stock cube crumbled in. I whizzed up a third of the mixture with oats and nuts to make a pate and added lentils to the rest of the mushrooms.

Mushroom, Lentil & Nut Wellington

A rich mushroom, lentil and nut wellington in golden, crisp puff pastry. The most luxurious pie to serve up as a vegetarian and vegan main course with roast potatoes, vegetables and onion gravy for Sunday dinner, Thanksgiving or Christmas dinner.
prep time: 30 minscook time: 25 minstotal time: 55 mins


  • 2 tbsp olive oil
  • 1 small onion, finely chopped
  • 1kg chestnut mushrooms, chopped
  • 1 tsp thyme
  • 4 tbsp red wine
  • ½ vegetable stock cube
  • 100g salted cashew nuts or peanuts
  • 2 tbsp porridge oats
  • 200g tinned green lentils, rinsed and drained well
  • 375g/1 ready rolled puff pastry
  • 100g spinach
  • 6 tbsp hummus


  1. Preheat the oven to 200c/180c fan/400f/gas mark 6 and take the pastry out of the fridge. Remove it from the box and place the rolled up pastry on a plate and let it come to room temperature so it doesn't crack when it is unrolled.
  2. In a large frying pan saute the onion and garlic in 1 tbsp olive oil until it is soft, then add the mushrooms and cook them gently until they are soft as well. Season with salt and pepper then add thyme, red wine and then crumble in the half a stock cube. Gently cook until all the juices are gone, then turn of the heat.
  3. In a blender or food processor and whizz up a third of the mushrooms with the oats and nuts until you have a pate texture. Set aside.
  4. Add the lentils to the rest of the mushroom mixture in the frying pan and mix well. 
  5. Rinse the spinach in a colander, then wilt the spinach by pouring a kettleful of boiling water over it. Refresh it with cold water, squeeze out as much water as you can then pat dry on kitchen paper.
  6. Carefully unroll the pastry and place it on a large baking tray, still on the baking parchment it was rolled in or on a baking sheet.
  7. Spread the hummus along one (long) side of the pastry leaving a border. Top with a layer of wilted spinach and the mushroom pate. Next top with the mushroom and lentil mixture. 
  8. Brush a little water around the edges of the pastry. Pull the pastry over the filling and seal to make a large sausage roll shape.  Crimp the edges with a fork and use a knife to cut diagonal slits in the top to let out steam. Brush with the rest of the olive oil.
  9. Bake or 20-25 minutes until golden and crisp.
  10. Serve slices with roast potatoes, vegetables and onion gravy.
  11. Enjoy

Extra Veg Vegan Shepherd's Pie

My family love shepherd's pie, well veggie shepherds pie of course. It's the ultimate winter comfort dish.

Savoury mince full of soft onion, carrot and mushrooms in a rich gravy topped with creamy mash that's baked until the mash is golden with crispy bits. We all love the crispy bits don't we?

I recently shared my original recipe for veggie shepherd's pie from 11 years ago on the Tinned Tomatoes Facebook page and everyone was talking about how good shepherd's pie is. It got me right in the mood for some, so I headed to the kitchen and made a pie much to my husband's delight.

I decided to use up some of the veg in my salad drawer to make it even more delicious and healthy. Shepherd's pie or cottage pie as it is sometimes known usually contains onions, carrots and mushrooms, but I included celery and red pepper, which worked really well and was very tasty.

Vegan Cowboy Beans & Potato Bake

A simple one-pot recipe for cowboy beans. Oven-cooked in one dish, this is a real fuss-free family dinner.

A black bowl with Vegan Cowboy Beans & Potato Bake

I needed a name for this savoury bake recipe. It's basically beans and sausages so it had to be cowboy beans. 

I have no particular knowledge about cowboys and what they eat apart from the black and white cowboy films with John Wayne I watched with my dad as a child.

Did they eat cowboy beans? Maybe! They certainly seemed to cook bean dishes in a pot over their fire.

So I'm calling these cowboy beans and on doing some research I realised I was pretty spot on, although my bean pot was going to include potatoes and as it is wet and windy outside I definitely wasn't going to be cooking them outside over an open fire.

Nope, the oven was fine for me.

Vegan Spinach & Cream Cheese Stuffed Pasta Shells - Crock-Pot Recipe

A simple weeknight recipe for spinach and cream cheese stuffed pasta shells. Quick and easy to prepare with a few ingredients.

Vegan Spinach & Cream Cheese Stuffed Pasta Shells - Crock-Pot Recipe

Let me start by saying my son Cooper gave this a score of 9/10. Get in!

It all began when Crock-Pot asked me if I could come up with an easy weeknight meal in a crockpot that wasn't a soup or a stew.

I'd been thinking about a recipe I made years ago. A vegetarian Conchiglioni Al Forno, which is a stuffed pasta recipe. I've been thinking about trying it again for a while but making a vegan version, so when Crock-Pot challenged me I knew just what to make.

Pumpkin Spice Shortbread Cookies (vegan recipe)

A simple recipe for vegan pumpkin spice cookies with a free printable recipe. If you don't have the individual spices you can use pre-mixed pumpkin spice or mixed spice.

Pumpkin Spice Shortbread Cookies

The season is changing and we're moving into Autumn (or Fall if you're elsewhere in the world). It's getting cooler, so we're wearing cosier clothes and layers.  Here in Scotland, a coat and umbrella are essential when you head outdoors. It's rather wet and windy here right now. So much rain!

Meals are changing too. Soups and other comfort dishes like shepherd's pie and chilli are back on the menu in place of salads and outdoor BBQs.

I'm also noticing a change in the recipes appearing on Pinterest (yes I spend way to much time browsing over there) and pumpkin spice is appearing everywhere. From lattes to cookies and cakes.
