Vegan Sausage and Sweet Potato Bake

I love an easy savoury stew baked on a tray or in a roasting pan. The kind of stew where you just throw it all in and let the oven do it's work.

They are so easy, so delicious and so satisfying.

The star of the show in this bake are the sweet potatoes and vegan sausages.

But let us not forget about the gravy.

Oh the gravy!

What are the best vegan sausages?

We like Linda McCartney Vegetarian Sausages, which are made from soya protein. They fry well, are great in bakes and don't fall apart. 

They are also accidentally vegan and no I have never worked with them, they are just our family favourite.

Of course there are a lot of different vegetarian and vegan sausages out there. Some are soya based, some are tofu based and some are vegetable based.

So much choice.

When you choose a vegan sausage, think of the final dish and the texture you are looking for before you choose.

Of course you could make your own sausages. Try my homemade puy lentil and mushroom sausages.

Do you have to brown sausages before adding them to a stew or casserole?

You can add sausages to stews and casseroles uncooked if they have a long slow cook, but they are much better if you cook them first.

Give them a good grill or fry until they are lovely and brown and crisp, then add them to the casserole. I really do think it improves the flavour and texture.

Or as with this bake, you can roast the sausages until crisp and brown, along with the vegetables.

What is the best vegan gravy?

When you make a bake, stew, casserole or something rather fabulously comforting like Slow Cooker Scottish Stovies and you want to add some gravy, it's easier to make it from gravy granules.

We like Bisto Onion Gravy Granules. It's easy to make a delicious gravy from these granules (just add hot water and stir) and it tastes great.

Of course you can make your own gravy if you have time. 

Try this vegan vegetable gravy or this homemade vegetarian gravy both from Easy Cheesy Vegetarian.

What's so good about this sausage and sweet potato bake?

  1. It's vegan
  2. It's easy to make
  3. It's full of healthy veg
  4. It it full of protein (thanks to the sausages)
  5. It is also packed with fibre (thanks to the sausages and vegetables)
  6. It's comforting
  7. It's filling
  8. It has the most amazing rich gravy
  9. It's cheap to make
  10. It's an instant family favourite

What do you eat with a sausage stew?

A sausage stew like this one is perfect when served with creamy mashed potatoes and vegetables.

You could also serve it as it is with some buttered crusty bread, but I like it with mash.

What to do with leftover vegetables?

The vegetables in this bake can be changed depending on what you have leftover in your fridge.

However if you make this recipe using the vegetables I used you could find yourself with leftover vegetables.

This recipe won't use a whole butternut squash and you may have red onions and sweet potatoes leftover.

So here are a few ideas:

Use leftover vegetables to:

  • Make soup - just cook them with onion and garlic and add stock and season with salt and pepper. You can whizz it smooth or keep it chunky.
  • Roast - roast vegetables can be tossed through pasta with some pesto, added to sandwiches or wraps or pilled up on a baked potato with some grated cheese.
  • Smoothies - leftover veg can be added to smoothies. If you aren't confident, start with a fruit base then add some veg. Turnips and onions should be avoided.
  • Stews - add them to stews and casseroles.
  • Sauce - add vegetables to a basic tomato sauce to add more flavour and make it more nutritious.
  • Grated - grate or shred them - and add them to sandwiches, salads and coleslaw. Like this Tex-Mex coleslaw.

Vegan Sausage and Sweet Potato Bake - Step 1 - Sausages

Step 1 - Sausages

Cut your sausages into chunks and add them to a large baking tray.

Whether you are roasting vegetables or sausages, they need a bit of room, if they are piled on top of each other they will steam and not roast.

Vegan Sausage and Sweet Potato Bake - Step 2 - Onions

Step 2 - Onions

Add peeled onions, cut into wedges.

I used red onions for their sweet flavour, but you could use regular onions.

Vegan Sausage and Sweet Potato Bake - Step 3 - Root vegetables

Step 3 - Root Vegetables

Next add some generous chunks of root vegetables. 

I added sweet potato and butternut squash as they are in season and give a wonderful flavour to stews, but you can add what you have or your own favourite vegetables.

Vegan Sausage and Sweet Potato Bake - Step 4 - Peppers

Step 4 - Peppers

Finally add a red pepper which has been washed, deseeded and cut into chunks.

If you have a different colour of bell pepper, fell free to use them instead.

Vegan Sausage and Sweet Potato Bake - Step 5 - Roast

Step 5 - Roast

Spray the vegetables and sausages with a little oil and season with salt and pepper and some dried thyme.

Roast in a pre-heated moderately hot oven until the sausages are brown and the edges of the vegetables are starting to char.

Vegan Sausage and Sweet Potato Bake - Step 6 - Gravy

Step 6 - Gravy

Make up your gravy in a jug, then pour it over the vegetables and sausages, giving them a stir.

Pop it bake into the oven to cook for a while longer.

Vegan Sausage and Sweet Potato Bake - Step 7 - Serve

Step 7 - Serve

Serve with mashed potatoes and extra veg.

  1. I love a good vegie bake - haven't done it with sausages so need to try that - I hope we have seen the last of the really hot weather and have some good baking season coming!

    1. I can't remember what hot weather feels like, it's been so damp and cold here for so long.

      Yes do try adding sausages it makes a bake really substantial. A meal in one pan.

  2. That looks so easy. I am going to try it. Jill

    1. Oh good, I hope you enjoy it Jill. Remember you can use up what you have in the fridge or buy the veg I used. Either would be good.

  3. This looks like such a satisfying recipe! I'm pinning this so I remember to make it later. :)

  4. What an easy and flavor-filled sheet pan meal. This came together in minutes and was incredibly delicious - thank you for a wonderful, easy to make recipe.

    1. Oh I am so glad that you tried it and enjoyed it Joanie. I do like to create easy recipes for my readers that my family and friends enjoy too.

  5. Great protein packed comfort meal! That gravy looks and sounds amazing!

  6. This bake is so delicious and easy to make! Great weeknight recipe.

    1. Yes it's totally easy enough to make midweek and so satisfying.

  7. I just love how easy this is to make! Perfect for a busy weeknight. :)

  8. Really like the sound of this! So easy to prepare and a great way to use all sorts of veg.

  9. Really not into sausages so I thought I'd just take a quick look but I ended up checking everything. I had tried cooking similar stuff before and that online delivery service, Feast Box, really helped me out try some ingredients that are hard to find like some listed above. Anyway, will forward this page to a couple of friends who are starting to get fond of cooking!
