I’m calling it – this has got to be the best butternut soup recipe ever! Best because it’s not just flavourful but it has minimal ingredients and requires very little effort.
- Simple to make – there is very little effort required on your part.
- So flavourful – from both the simple ingredients and the caramelisation after roasting them.
- Just 6 ingredients – in fact only 5 if you don’t add the optional chilli.
- Easily scalable – make more for a crowd or to freeze or less if you just want a simple meal.
- Perfect for dinner or a starter – fill up a big bowl and add some crusty bread for dunking or serve a small bowl to start a meal.
- Healthy – just wholesome ingredients turned into a cosy meal.
- Great for meal prepping – you can prep this ahead for weekday lunches or even freeze big batches when you see butternut on sale.
I call this sort of food soul soothing because it’s nourishing and healthy but tastes super comforting all at once. It’s served here with Sizzler cheese toast / parmesan toast (which I also freeze in big batches) or if I’m feeling extra, these mini grilled cheese are great too.
Has the cooler weather hit? Need a warming soup? Try this roasted tomato soup with the cutest mini grilled cheese sandwiches or this hearty roasted garlic and potato chowder.

How to make butternut soup
You could just throw all these ingredients in a pot and boil it all up until everything is tender but what makes this easy butternut squash soup really amazing is the flavour you get from roasting the squash instead, along with some onion and garlic.
Jump to the recipe for full ingredients and instructions.
- Roast the veggies: After chopping just a little off the ends to make them flat, carefully cut the butternut in half (photo 1). Scoop out the seeds (photo 2) and place them on a baking tray. Add the onions and garlic to the seed cavities (photo 3) and roast until soft and caramelised (photo 4).
- Blitz the soup: Add the butternut flesh, onion and garlic to a blender (photo 5) then add chicken stock (photo 6) and blend until super smooth.
- Heat the soup: It will cool after you add the chicken stock so heat it in a large pot.
This soup is also wonderful served with these Cheese and garlic croutons.
How to roast butternut squash
This is a roasted butternut squash soup recipe. Roasting the vegetables, caramelises them and gives them a sweeter flavour making it the perfect way to add extra flavour to this soup. To roast butternut squash:
- Start by cutting a thin slice off the base of your butternut – just so you have a flat surface, and remove the stem at the top end.
- Now stand it up on it’s flat end and use a sharp knife to cut directly down the centre.
- Use a spoon to scoop out the seeds and any string bits, leaving a round cavity.
- Place the butternut on a baking tray lined with baking paper.
- Score the flesh about 2-3mm in depth with a sharp knife into the flesh.
- Rub or brush a little oil over the top then sprinkle some salt and pepper over the top.
- Roast in a preheated 200C / 395F / 180C oven for 45 minutes to an hour or until the flesh is soft and the top is caramelised.
The roasting time will depend on how large your butternut squash is.
Pro tips and tricks
- Score the butternut: Use a sharp knife to score squares in the top of the butternut. This allows for more caramelisation of all those edges.
- Skip the blender: Using an immersion blender directly in the pot you’re heating the soup in is actually my preferred method but I know not everyone owns an immersion blender. Put all the ingredients in a dutch oven or large saucepan on the stove. Bring to a boil then either use an immersion blender right in the pot.
Variations
- Pumpkin: Swap the butternut squash for any type of pumpkin.
- Vegan butternut soup: Swap the chicken stock for a good vegetable stock to make it vegan.
- Cream: To up the creaminess and cosy factor, add some cream drizzled over the top before serving.
- Carrot: Add a large carrot when roasting for extra flavour and sweetness in the soup.
This soup is amazing topped with crispy bacon, croutons, pepitas and / or some thyme leaves. You could also try a little sage fried in butter first. Delicious! Always serve this with some crusty bread too for dunking.

2 kg equals 4.4 lbs. I’m assuming 2 kg is correct.
