Roasted Butternut Squash Soup

This Roasted Butternut Squash Soup is easy to make and bursting with flavour. It’s creamy (without cream), rich and totally delicious!

Butternut squash makes such a quality soup. There are a few different ways you can make it, but today I’m going to show you what I deem to be the BEST way 😋. Follow me…

Roasted Butternut Squash

The absolute key to this soup being so delicious is roasting the butternut squash. When you roast the butternut squash low and slow, it releases the natural sugars, that in turn caramelize. It completely transforms the flavour. I don’t know if you’ve ever made soup by boiling butternut squash or even sweet potato, but the flavour of this soup in comparison is next level.

Roasted Garlic

In with the squash, we’re going to add some whole cloves of garlic. Roasted garlic compliments the flavour of the squash so beautifully. When you roast garlic it goes gorgeously sweet and nutty. No need to peel the garlic, just whack it straight inside the squash (I mean c’mom, how neatly do they fit in those dents!?).

Alrighty, when it comes to roasting butternut squash, I promise you it couldn’t be easier.

How to Roast Butternut Squash Whole (quick summary)

1. Cut off the very end of the butternut squash.
2. Slice horizontally and scoop out the seeds.
3. Make a crosshatch pattern, slicing as deep as you can without going right through.
4. Brush with olive oil, honey, cayenne pepper, salt and rosemary, then add a clove of garlic to each one. Roast in the oven until soft and caramelized.

Roasted Butternut Squash Soup

Once you’ve roasted the butternut squash, it’s pretty straightforward from there. Whilst they’re roasting you’ll start frying your onions low and slow in butter. The butter will offer an extra creaminess to the soup, without having to use cream.

90% of the time I make this soup I’ll use chicken stock, as I feel it offers slightly more richness than veg stock. But veg stock does work as a great sub.

How to make Roasted Butternut Squash Soup (quick summary)

1. Allow the roasted butternut squash to cool.
2. Scoop out the flesh and squeeze out the garlic.
3. Meanwhile fry the onions in butter until caramelized.
4. Add butternut squash/garlic into the pot, pour in stock and blitz with a hand blender.

Butternut Squash Soup FAQ

What if I don’t have a hand blender?

If you don’t have a hand blender, you can use a regular blender. Just check the temperature limits of the blender and make sure you blitz with the small top opening off (place a tea towel over it). This will ensure the steam doesn’t burst/crack the blender.

Can I make this soup in advance?

Absolutely! In fact, the flavours are likely to develop as it rests so it’ll be extra tasty. Just allow it to cool, then store it in an airtight container in the fridge for a few days or in the freezer for a few months. Reheat on the hob.

How many will this soup feed?

It’ll give you 4 hearty bowls for dinner, or 6 as a starter/side.

Serving Butternut Squash Soup

As you’ll see in the video/photo below, I served this with a grilled cheese. More specifically a cheddar, gouda and apple grilled cheese. This is completely optional though. Alternatively you can’t go wrong with just chunks of buttered bread!

Butternut Squash Soup Toppings

Two absolute game changers to add to this soup are crispy pancetta and toasted pine nuts. I HIGHLY recommend using both. I also use a dash of fresh parsley for a pop of colour and a touch of flavour.

Alrighty, let’s tuck into this homemade butternut squash soup recipe shall we?!

Instructions 

• Slice off the very end of the squashes and carefully slice them in half lengthways. Gut out the seeds, then slice a crosshatch pattern in each one (don't slice all the way through, this is just to allow the flavour to seep in). Place on a large baking tray.
• In a small bowl combine 2 tbsp olive oil, 1 tbsp honey, 1 tbsp fresh rosemary, 1/4 tsp cayenne pepper and 1/4 tsp salt. Brush the squashes, then pop a clove of garlic in each of the dips.
• Place in the oven at 190C/375F for 45-60mins, or until very soft and caramelized. Don't be tempted to rush this, low and slow is key to getting beautifully caramelized and fork-tender butternut squash. Pull the tray out 1 or 2 times to baste them in the juice that collects in the dips.
• Meanwhile, in a large pot begin frying the onion in 2 tbsp butter over low-medium heat until soft, golden and caramelized. Again, low and slow is best.
• Scoop out the flesh from the squashes and place into the pot, then squeeze the garlic out of the skins and add that in too. Pour in stock and blitz with a hand blender until smooth. If you want it thinner then just gradually add in more stock. If you go overboard just simmer to thicken. Season generously (to taste) with salt and pepper.
• Serve hot with toasted pine nuts, pancetta and a teeny pinch of parsley.

Notes

a) Grilled Cheese - As you can see in the video above I've served this with a grilled cheese consisting of Gouda, Cheddar and Apple. Apple + butternut squash is a glorious combo, plus the apple adds a nice crunch to the sandwich. You don't have to add apple (if you do just make sure it's preferably a red variety and thinly sliced into rounds). Also make sure the cheddar is mature/sharp, just for a punch of flavour.

b) Spice - I highly recommend using cayenne pepper, the gentle spice plays beautifully with the sweetness of the butternut squash. 1/4 tsp adds a nice gentle background tingle, but if you're really not good with heat consider 1/8 tsp or just a pinch, then adjust accordingly at the end.

c) Seasoning - Bring out the best in this simple soup with a good amount of salt and pepper. Keep taste testing until 100% happy!

d) Toppings - I HIGHLY recommend adding the pancetta and pine nuts on top. They compliment the soup amazingly. If you're struggling with pancetta, bacon would sub. Parsley is to add a pop of colour and a smidge of flavour, but definitely don't go overboard. Just a teeny bit to finish. You can leave this out if you wish.

e) Stock - I recommend pouring it in gradually and working to preference. Feel free to add more or less for a thicker/thinner soup. I mostly use chicken stock as I find it to be richer, but veg stock does work well too.

f) Blender - If you don't own a hand blender, you can use a regular blender. Just check its heat resistance before using it. You'll have to take off the small bit at the top and place a hand towel over it. This is so the steam doesn't get trapped inside and causes the blender to crack.

g) Leftovers/Make in advance - You can certainly make this in advance! Store in the fridge for a couple of days or freezer for a few months. Let it cool before storing. Reheat back in the pot, if it's frozen I recommend letting it come to room temp first.

h) Calories - Based on just the soup shared between 5 people.
