Mash Topped Vegetable Pie (Veggie and Vegan Options)

A simple pie of vegetables in a cheese sauce topped with mashed potato. Comfort food at it's best. Vegetarian and vegan options.

Comforting Pies

It's getting cooler up here in Scotland, so salads are being pushed aside in favour of more comforting dishes like this mashed potato topped vegetable pie.

I do love a comforting pie and it seems like you do too as my pies are all really popular.

If you haven't seen my other pies, check out my Vegan Lentil Shepherd's Pie which is also topped with mashed potato; my Cottage Vegetable Pie which is a bit like a veggie shepherd's pie but has a lot of vegetables in it and my Cheesey Vegetable Pie which is also vegetables in cheese sauce, but topped with golden, crispy pastry.

Family Recipe

This isn't one of my best photos, but it's a great family dish.

A mixture of vegetables in a creamy sauce topped with mashed potato and baked until the surface of the mash is crisp and golden and the sauce is bubbling.

We all love the crispy bits on a bake like this, don't we?

This pie is frugal, it's comforting, it's filling and we all really enjoyed it.

I made two versions of this dish, a veggie one for Cooper and I with a mature cheddar cheese sauce and one with a vegan cheese sauce for Graham.

Blender Cheese Sauce

I made the cheese sauce for this pie (both a vegan and a vegetarian sauce) in my power blender.

Did you know you can make a cheese sauce in a blender?

I was inspired to make sauce in my Optimum 9400 blender after seeing a blender white sauce over at The Crafty Larder.

The blender sauce was a little thinner than usual, but it was silky smooth and so quick to make.

I'll definitely be making cheese sauce this way again. Of course if you don't have a powerful blender like mine, you can whisk the sauce in a pot the traditional way.

Frugal Recipe

You can use any vegetables you have languishing in the fridge or freezer or simply choose your favourite veg.

This is a really frugal recipe that doesn't break the bank.

It's also a great way of getting your 5 a day in one meal. I think we all need to try and eat more vegetables than we currently do. Don't you?

I do hope you try this recipe and enjoy it as much as we did.

Mash Topped Vegetable Pie 


This pie is a real comfort dish and although it has a cheesey comforting sauce, which contains fat, it isn't too calorific and because it has so many vegetables it can still be seen as a reasonably healthy dish.

There are 524 calories in 6 portions and 786 calories in 4 large portions.

The pie is high in potassium, vitamin D and iron and a good source of calcium.

A comforting and economical family pie of vegetables in a creamy sauce topped with mashed potato and baked until golden.


  • 4 carrots, sliced thickly
  • 1 cauliflower, cut into florets and then halved
  • 340g  tin/2 cups  sweetcorn
  • 1kg potatoes, peeled and quartered
  • 5 tbsp olive oil (for the mash)
  • 2 tsp olive oil (for the mushrooms)
  • 4 large flat mushrooms, sliced
  • 60g butter (dairy free spread) for the sauce
  • 7 tbsp plain flour
  • 300ml milk (unsweetened soy milk)
  • 120g mature cheddar grated (vegan cheddar & vegan parmesan)
  • ½ tsp English mustard powder (optional)
  • a good grinding of salt and pepper


How to cook Mash Topped Vegetable Pie

  1. Preheat the oven to 220c/fan 200c/gas mark 7
  2. Steam or boil the cauliflower and carrots until just tender, drain and set aside.
  3. Steam or boil the potatoes until soft, mash with olive oil and season with salt and pepper.
  4. Gently fry the mushrooms in the olive oil, season these too.
  5. While the vegetables are cooking, make your cheese or dairy free sauce. Either whizz in a high power blender for a few minutes, then leave to thicken or whisk over a low heat in a pot until smooth and thick.
  6. Mix together the cooked vegetables and corn and coat in the sauce, then pour into an ovenproof dish and top with the mashed potato. 
  7. Bake for 20 to 25 minutes until golden and bubbling.
  8. Serve with crusty bread or garlic bread.
  9. Enjoy!


I have added vegan parmesan to the ingredient list as vegan cheddar can be quite mild, so the parmesan adds extra flavour.

You can also add veggie parmesan to the vegetarian cheese sauce if you want more of a punch of flavour.

Comforting Recipes for Cold Days

comforting recipes - chilli and curry

Disclosure: I mentioned my power blender in this post. I've been using it for 6 years now and love it. I do work with Froothie, but I was not expected to write a positive review and comments are my own.


  1. oooh, I really like the inclusion of sweetcorn in this, I often get stumped with the same veggies in my pies but never use sweetcorn, that's lovely... so glad we're approaching pie weather!

    1. Cooper loves sweetcorn so we do tend to include it a lot. but it is actually great for little bursts of sweetness.

  2. Looks for hearty and comforting Jac! Like Dom, I'm liking the fact we are approaching pie weather. And Iike the idea of the sauce. Another great use for the Optimum 9400!

    1. I'd rather keep the heat of summer for another month or two. The cold weather approaching just makes me sad.

  3. Love how you;ve made the sauce in the blender. Must give that a go. I have a quick method but this looks even quicker which is always good on a weekday!

    1. I know, It's super quick, so ideal for weeknights.

  4. The past few days have been very disappointing weatherise. Usually we are still in short sleeves but today I contemplated wearing gloves! (I'm a southern US softy though). But the consolation is yummy, comfort dishes like this family-frienly pie. Like Dom I don't think to use sweetcorn this way but it is a great idea. I can't digest corn but I could keep a corner a corn-free zone just for me. ;-) Thank you for linking to my black bean quinoa chilli too. I think it is time to pull out my slow cooker...

    1. It's just to early in the year fr it to be this cool. I mean its still August. It's a pity corn doesn't agree with you Kellie, it' such a nice addition to dishes.

  5. Mmmm yum that pie looks good. Cold here too now so that's just the thing.

    1. I know. I had planned for lots of salads but I don't think that is going to happen now.

  6. I think it's a fab photo, I just want to get a fork and dive in... Any Ieft?

    1. Thanks Fanny, although I am still not happy with it, but it was very tasty. And no sorry, it's all gone now.

  7. This looks fantastic! It's definitely getting towards pie season; can't wait! It's getting a little cooler down here too, and salads aren't looking as appealing as earlier in the summer. Will certainly give this a go, and the sauce in the Optimum too!

    1. The optimum is definitely a time saver. Pity about the weather though. I am fighting against putting the heating on until October, but it is cool today.

  8. Goodness this sounds dreamy! I have a craving for a veggie shepherds pie now :)

  9. There is something beautiful in the ugliness of the irregular imperfection of the topping and the drips. This is how home cooked food should look! A great dish for the veg gardener, I can add a bit of everything.

  10. Looks a great dish. Really hearty and warming. Plus very filling. Excellent thank you.

  11. This looks so rustic and delicious! Something very Jamie Oliver about it... It is still hot here in the States but I look forward to trying this :)

  12. My goodness you love your optimum blender don't you. I like the idea of making thins sauce in a blender.

    1. Haha you've noticed and yes I do. Such a time saver.

  13. Now this is the sort of food I want to eat this season in all its comforting, nourishing and tasty wonderful ease x

  14. Hi, I made the pie, but it seems to me the ratio of the cheese sauce are not correct, more milk is needed to make the cheese sauce for all the vegetables to be coated properly in the white sauce. Overall, a very delicious pie!

    1. Always add more if you think you need it in a cheese sauce I measure what I use but a simple difference in cooking temperature can mean the milk evaporates quicker. Hlad you enjoyed it. Have a wonderful Christmas x

    2. Goodness you are right, that must have been a typo. Let me find my notes and update it.
