 Vegan burger & onion bake is a super simple sheet pan dinner. Vegan burgers are roasted with vegetables then topped with a tasty sauce and cheese.

Vegan Burger & Onion Bake


This vegan burger and onion bake is super easy to make and oh boy did we enjoy it.

I started by parboiling some baby potatoes to get them started, but apart from that, everything was cooked in the oven on a sheet pan.

It's just delicious. 

I don't know why I didn't think of it before.


What type of vegan burgers to use in a bake?


This is not the type of dish where you use a bean burger or vegetable burger.

You are looking for a soya style of burger, that looks more like a traditional burger.

We've tried a few different types but decided we prefered the Green Cuisine Meat-Free Burgers, which are made with pea protein and include no artificial colours or flavours.

And no I don't work with them, but I thought you might ask which burgers I use.

An Easy Vegan Sunday Roast


If you are looking for a super easy vegan Sunday roast, this is a good option.

It is much less work than a normal roast as the veg all cooks together and you still get your little roast potatoes.

A roast usually comes with gravy, but this one includes a thick layer of sauce on the cooked burgers, so you just don't need it.

It's nice to taste the smoky flavour of the roast vegetables and not have them swamped with gravy.


What You Need to Make a Vegan Burger & Onion Bake


Equipment

  • Pot - to pre-boil the potatoes
  • Sheet Pan - if you don't have a sheet pan you can use a roasting pan or baking tray, or even two if your tray isn't big enough

Ingredients

  • Vegan Burgers - soya or pat protein burgers work well for this bake
  • Onions - white onions
  • Red Peppers - yellow or orange bell peppers would work well too
  • Mushrooms - any standard mushrooms (not wild mushrooms)
  • Baby Potatoes - you could use any potatoes you have, just chop bigger potatoes into smaller chunks
  • Olive Oil - just a drizzle
  • Salt & Pepper - to season
  • Tomato Sauce - loaded onto the cooked burgers
  • Vegan Cheese - grated cheddar or smoked cheese


Which Type of Tomato Sauce?



I used jarred tomato sauce for this bake, but you could make your own sauce.

This simple tomato and basil pasta sauce would be delicious on the burgers.

Supermarket own-brand tomato and chilli pasta sauce was my choice for this bake.

If you are buying jarred sauce, look for one that's quick thick and not an oily sauce. 

Leftover sauce can be used to make homemade pizza on naan bread, pitta bread or bagels. You could also keep it for a quick pasta or adding to a toastie.


Which Type of Vegan Cheese?



Use your favourite vegan cheese (or whichever cheese you love) for this bake.

Vegan smoked applewood cheese is a good option for this bake as it melts really well.

I used up what I had, so used two different kinds of cheese.

If your favourite vegan cheese doesn't melt well, a wee tip is to mix a little cream cheese into the cheese before spooning it over the sauce.

How to Serve Vegan Burger & Onion Bake



Here are some ideas for serving this bake:

  • JUST SERVE IT UP - Just serve it as it is
  • EXTRA VEG - Serve it with some green veg, broccoli and mangetout would be good
  • BURGER BUN - Serve your topped burger on a bun with the veg on the side


How to Tweak this Recipe



You can make a few tweaks to this recipe:

  • VEG SWAP - change up the veg, think of all the veg that tastes so good roasted - carrots, butternut squash, sweet potatoes, aubergine, courgettes ............
  • PULSES - why not add chickpeas to the bake
  • BBQ SAUCE  - swap the tomato sauce for BBQ sauce and skip the cheese

Vegan Burger & Onion Bake

A simple vegan burger & onion bake with extra veg. A whole meal cooked on one tray. Simply delicious.
Prep time: 10 MinCook time: 45 MinTotal time: 55 Min

Ingredients

  • 12 baby potatoes, halved
  • 4 vegan burgers (soya based or pea protein style work well)
  • 2 large onions, sliced
  • 1 red pepper, sliced
  • 4 mushrooms sliced
  • 8 tablespoons tomato pasta sauce
  • 8 tablespoons grated vegan cheddar
  • 1 tbsp olive oil
  • salt and pepper

Instructions

  1. Parboil the halved baby potatoes in a pot with boiling, salted water for 10-15 minutes until starting to become tender but not soft.
  2. Prep your veg.
  3. Preheat your oven to 180c/160c fan/350f/gas mark 4.
  4. Add your burgers to a sheet pan, baking tray (or two) or roasting tin.
  5. Add a layer of sliced onions, then add sliced peppers and mushrooms. 
  6. Now add the drained, parboiled potatoes. Try to keep everything in a single layer as much as possible.
  7. Drizzle with olive oil and season with salt and pepper.
  8. Pop in the oven to roast for 20-25 minutes until the burgers are well cooked.
  9. Top the burgers with a thick layer of tomato pasta sauce, then grated cheddar and pop the tray back into the oven to roast for another 10-15 minutes until the cheese is melted and the potatoes have nice roasty skins.
  10. Serve and enjoy!

Notes:

  1. You can easily add more burgers and veg to serve more people.
  2. Why not sprinkle some dried herbs over the cheese and vegetables for the last bake.
  3. You can use jarred tomato sauce (I used a tomato and chilli sauce), but look for one that is thick and not oily.
  4. You could also make a fresh tomato and basil sauce.
  5. This bake doesn't work well with vegetable or bean burgers.
  6. Why not serve the topped burgers on burger buns and the veg on the side?
