Making the butternut squash burgers healthier
This recipe for yummy butternut squash and sweet potato veggie burgers can be changed around. It can easily be made to be healthier.
Firstly omitting the mayonnaise or swapping to lighter mayonnaise can make a small difference.
If you use wholemeal bread rolls it would be a little healthier than a brioche bun.
The total flour used in the recipe is negligible and I wouldn’t worry about changing it or omitting it just to save a few calories.

Making these burgers on a budget
The total cost of this butternut squash and sweet potato veggie burgers recipe is pretty good. There are though a few places money could be saved. Watch out for when the Merchant Gourmet packs are on offer. They have a good expiry so will keep them until you need them.
Buying frozen diced butternut squash and sweet potato saves time and can often work out cheaper too. If you would like to use fresh then check out my butternut squash tips.

What about using a different squash?
The most common squash in the UK is the butternut squash but there are many other varieties of squash you may see in the shops, especially in the autumn. Have you considered experimenting with different squashes?
There is no reason you couldn’t make this with another squash of your choice if you are sure you enjoy it. They all have similar but distinct flavours so it is worth trying roasted squash first for different varieties and then if you enjoy it experimenting with that variety in recipes such as these burgers, risotto or soup.
Why does butternut squash go so well in veggie burgers?
As a vegetarian, I’m constantly looking for new and delicious meals to satisfy my hunger. One of my favourite go-to choices are veggie burgers, and I’ve recently found a secret ingredient that takes them to the next level: butternut squash!
I’ve always loved the sweet and nutty flavour of this versatile ingredient, and it turns out it packs a serious punch when added to veggie burgers. Not only does it add subtle sweetness to the patty, it also acts as a binding agent, helping to hold everything together.
And if you’re looking for an extra boost of nutrition, butternut squash is loaded with vitamins and minerals, making it a win-win choice for an irresistible veggie burger. Trust me, once you try it, you won’t look back!
What to serve the burgers with
I would recommend serving with a good size salad, chips and coleslaw or whatever takes your fancy. I have a coleslaw recipe you should try if you have time to make it healthier.

Description
A good healthy veggie burger that is perfect for all the family
Ingredients
350g diced butternut and sweet potato
250g pack Merchant Gourmet smoky spanish-style grains and rice
2 tsp smoked paprika
25g pack flat leaf parsley roughly chopped
1 lemon, zest plus juice to serve
1 tsp plain flour, plus extra for dusting
2 tsp frylight
4 brioche burger buns
2 garlic cloves, crushed
4 heaped tbsp mayonnaise with a sprinkle of pepper to add a bit of flavour
120g peppery salad or any salad you would like
Instructions
1. Simmer the squash and sweet potato in salt water for 8- 10 minutes until tender, then drain and mash. Let it cool then, mix with the grains and rice, 2 teaspoons of paprika, chopped parsley, lemon zest and 1 teaspoon of flour. Season well to your tastes. Shape into 4 burgers, dusting your hands with a little flour to help.
2. Heat the frylight in a non-stick griddle pan and cook the burgers over a medium heat for 5 minutes on each side until darkened and golden. Stir the garlic into the mayo (Ben had the idea of putting in a little parsley too, I thought he was mad but I was wrong!) and mix well.
3. Put a handful of salad leaves on each bun bottom and sit a burger on top. Add a good dollop of garlic mayo (we put in pepper to taste aswell). Put each on a plate and add the bun top and garnish with the salad and take a bite! Bon appetit!

Tasty veggie burgers. Took a while to find the Merchant Gourmet pack – glad I did though. Well worth the wait!
Hi, does the recipe require 350gs of sweet potato & 350gs of butternut squash or just 350gs as a combined weight?
Apologies, that is the combined weight
lovely recipe.
can i freeze them?
Yes they should freeze well but I would defrost before cooking to ensure they cook thoroughly.
